Application August 18, 1934, Serial No. ‘740,388 4 Claims. This invention ‘relates to a system of building structures, wherein the walls are provided with .or ‘formed of exposed building units. ‘The chief object of this invention is to provide a system of building units whereby certain ar chitectural ornamental formations in structural walls maybe obtained witha minimum of special 0 units, special equipment, special workmanship andspecial labor. it) _ The chief feature of the invention consists in providing a minimum number of building units (01,. 72-18;) pared with previous installations constructed as aforesaid and this reduction is obtained through the overlapping feature ‘possible with the use of units embodying this invention, whereby exact predetermined positioning of ends of Walls, open commodate the regular coursing of mortar joints, is not required; neither is “humoring” of the joints of the included structural units in any one course required or necessary; and neither is‘it formation and of the desired shape, depending necessary to bring the vertical coursing to any predetermined height of ‘wall or opening which heretofore has been necessary for the placing of upon the particular purpose for which it is to be sills, lintels and underbeams. which may be of any desired outline or surface ' used and providingr therein one or more angularly ,outlined arranged portions which are relatively detachable, whereby the composite unit may be completed and handled in its entirety until im ‘ .rmediately prior to its. incorporation in the wall :structure, whereupon the detachable portion, or portions, is readily removed by the use of a trowel, hammer or like instrument. .Another and useful corollary feature of the invention consistsin the ‘formation of a masonry 25 unitof the aforesaid character, which, when one ,or more readily detachable portions is removed therefrom, is adapted to overlap and/or shroud a portion of a wall comprised of a plurality of standard building units, such as facing brick, 30 structural facing tile and machine made terra cotta, as well as of plaster and other like sur faced constructions. i) ings, and the like, heretofore necessary to ac ’ A further feature of the invention consists in the elimination of the precise cutting of’ many mitres of the standard abutting units for arched openings andinclined ornamental units, such as stair ‘risers, ramps, et cetera. ' ‘It is to ‘be understood that units of this general 20 ‘character, although not necessarily, preferably ‘are of ‘a ‘structural facing tile type in that they are of a ?red material. While structures of ?red materials, by reason of the variation in shrinkages during the ?ring operation, heretofore have increased the cost of building structures of this type, because the vari ation in each unit had to be held to a predeter mined minimum, thereby resulting in an enor mous culling cost, withthe present invention, due to the accommodation feature provided by the overlapping inherent in the invention, most of To appreciate the utility of this invention, it need only be mentioned that heretofore in build ing wall structures of structural facing tile, fac ing brick, and the like, and particularly with structural tile, it was and is necessary for the the culled units are susceptible of inclusion in the structural wall of the character set forth, thereby furtherdecreasing the cost of the com 35 architect to position according to predetermined formation ,of [the several units in substantially block form with a removable angle, reduces defor mationduring the ?ring andbreakage to a mini 40 mum during handling and transportation, until positions, his various openings precisely as de 40 termined by the standard sizes of said units. Whenever such openings were thus not posi tioned, the aforesaid standard structural units had to be cut to special lengths or heights with a smooth edge, thus resulting in an enormous wastage or the consumption of a large amount of time,,-or the use of expensive machinery such as‘ carborundum saws, and the like, thereby in creasing the cost of a wall structure of this character to the extent that the same can only be utilized in the more expensive homes and buildings. ‘The present invention through its overlapping feature permits the use of structural tile, brick, and the like, whenever and wherever desired and 55 at a very materiallyless cost of the same as com pleted structural wall. ' It is also apparent from the aforesaid that the the ,unit is .to be actually installed, thereby fur ther-reducingthe cost of a structural wall em bodying this invention. -It will also be apparent from-the aforesaid that by reasonof the accommodation factor inherent in the invention that the architectural cost is reduced to aminimum because accurate and pre cise positioning of openings is not required and second, exact and precise positioning of the archi 50 tectural features inthe wall are not required and this accommodation factor also permits of con— siderable ?exibility in architectural design at sub stantially lesser cost than present construction, wherein it is more expensive to provide an open 55 2 2,036,131 ing than it is to build a flat wall, particularly if the opening has any decorative value, whereas with the present invention, decorative openings may be provided at substantially the same or lesser cost than the cost of the plain wall. The chief purpose, therefore, of the present invention is to bring the heretofore relatively ex— pensive, ornamented tile wall within the price Fig. 7 is a view similar to Figs. 1 to 6, inclusive, but shows an oppositely directed overlapping por tion associated with an angularly removable por tion, and the dotted lines extending across the two adjacent walls representing an additional alternative removable L-shaped portion, the dot ted line I01’ at the corner representing a modi ?ed form of contour. range of plain wall structures, which use struc tural units and are without architectural orna Fig. 8 is a transverse sectional view of an in ternal corner or cove unit, there being two units mentation. shown back to back and arranged for parting at the median plane. The present invention permits the employment of different colors and textures between the wall structure proper and the architectural ornamen 15 tation. Also the wall structure units and the architecture ornamentation units need not be of a predetermined ratio as to size, which hereto fore has been necessary by reason of the precise engineering determination. In general also this invention in its incorpora tion in the building structure permits the build ing of the wall structure of the standard units, leaving the desired openings for subsequent ?n ishing with the architectural ornamentation units embodying this invention and at a later date if necessary, permitting the owner of the building to select diiferent colors and textures as desired, which will furnish the desired color combination and desired architectural ornamentation that the ‘owner of the building determines by comparison with the wall to be what he wants. Also, this invention has the advantage that if the architectural ornamentation should be in corporated in the wall structure as it is being Fig. 9 is a transverse sectional view of a two wall external corner unit provided with two L-shaped detachable portions providing oppositely direct ed overlapping portions and a central corner forming portion, the dotted lines illustrating a modi?ed form, wherein an additional central portion may be included. Fig. 10 is a transverse sectional view of a unit similar to Fig. 9, the detachable portions being of angular arrangement in cross section, rather than of L-shaped and the dotted lines extending across the two connected walls representing al ternative additional reliefs, permitting further ' detachment or reduction of the unit as required, the central dotted lines extending from the top to the bottom of the ?gure representing an al ternative modi?ed form, wherein a central ad ditional wall is provided. Fig. 11 is a transverse sectional view of a form of the invention which is of recessed type on its face and is provided with two oppositely directed overlapping portions, two oppositely directed, 35 built up and if for some reason or other one or more architectural units become lost, broken or for some other reason, or the architectural units readily detachable, L-shaped portions and a cen- ‘ are delayed in manufacture, then such delay, for whatever cause, does not delay the progress to 40 ward completion of the building. In other words, unit of Fig. l of the reverse form united by the common wall, the dotted lines representing an the building may be entirely completed, except for the architectural ornamentation just as at the present time in building structures, the en tire building is completed and then the wood trim 45 is applied to the several openings. While the invention has been shown speci? cally applied to a structural unit wall, it need not necessarily be applied thereto, because in re modeling or in redecorating the ornamental pan 50 els may be utilized to replace wood trim in the present structures. Likewise, the same replace ment may be e?ected for the framing of windows when the Wood trim only is to be replaced. The full nature of the invention will be under stood from the accompanying drawings and the following speci?cations and claims: In the drawings, Fig. 1 is a transverse sectional View of a building unit used generally as a clo sure and having an L-shaped removable portion to provide a projecting wall for overlapping pur poses. Fig. 2 is a View similar to Fig. 1 and of a simi lar type of unit; however, of slightly different surface contour. Fig. 3 is a view similar to Figs. 1 and 2, and of a similar unit and of slightly di?erent surface contour. Fig. 4 is a view similar to the preceding ?gures and of a unit having a diiTerent surface con 70 tour. Fig. 5 is a view similar to Figs. 1 to 4, and of a still further modi?ed form of contour of the unit. Fig. 6 is a similar view of still a further modi ?ed form and is similar to Figs. 1 to 5 inclusive. tral connecting wall or portion, Fig. 11 being substantially a duplicate of Fig. 1 plus another additional modi?ed form, permitting the removal 40 of additional detachable L-shaped sections. Fig. 12 is similar to Fig. 11, as illustrated, by the full lines thereof, except that in this form the central partition wall is omitted and in this respect is a duplicate of the upper two-thirds of Fig. 1, plus the addition of a reversed portion equal to the upper two-thirds of Fig. 1. Fig. 13 is an enlarged transverse sectional view of a false sill unit and previous to the removal of the two readily detachable L-shaped sections and 50 is somewhat similar to the form of unit shown in Fig. 7. Fig. 14 is a transverse sectional view of the composite unit similar to that shown in Fig. '7 in that it illustrates a rounded corner and the "5 molded contour shown dotted in Fig. 7 and it in cludes a successive series of L-shaped, readily removable sections associated each with the other and with a common integral wall. Fig. 15 is a transverse sectional view of the unit similar to Fig. 14 showing an additional L-shaped removable section for the same overall dimensions and outline. Fig. 16 is a transverse sectional view of a unit similar to Figs. 14 and 15 having a still greater number of L shaped removable sections for the same over-all dimensions and outline. Fig. 17 is a sectional view of a double cove unit similar to that shown in Fig. 8, each half unit having an integral extension and an L-shaped readily detachable portion. Fig. 18 is a front view of a right hand sill starter unit embodying the invention. Fig. 19 is an end view thereof. Fig. 20 is a top plan view thereof. 75 '3 2,036,131 In the drawings, Figs. 1 to 6, inclusive, illus trate different contoured units which are sub stantially alike functionally. In Fig. 1 of the drawings, the numeral 4I indicates the front wall ‘of the unit. This is the exposed and suitably ?nished face. The numeral 42 indicates another exposed and ?nished wall and the two are shown connected by the Walls 43 and 44, forming a tubular unit. For doweling purposes, and the like, at suitable 10 intervals, and preferably at corners, the recesses or openings 50 may be provided. Projecting from the wall M, as a continuation thereof but offset from the face of wall III, is the wing extension 45. ,15 In other words herein the back of wall 450. is positioned so as to lie in a plane forwardly of the front of wall 4Ia by the difference of a mortared joint. The purpose of this will be set forth more fully hereinafter. ,20 United to the end of wall 45 and to the junction of walls 43 and 44 and at 4-8 and 49, is an L-shaped ‘portion 46 and 41, the portions 48 and 49 being reductions in the walls 46 and 41. These reduc tions permit the L-shaped portion 46-41 to be readily detached by a trowel or the like, from the remainder of the unit, leaving a tubular unit with the projecting wall 45 when thus detached. In Fig. 2 similar parts of the unit shown therein bear numerals from 5i to 50, inclusive, corre sponding to the same parts in Fig. 1. In Fig. 3 the similar parts bear numerals from BI to 10, inclusive. In Fig. 4 the similar parts bear numerals from "H to 80, inclusive. In Fig. 5 the similar parts bear numerals from 8| to 90, inclusive. In Fig. 6 the similar parts bear numerals from 9| to I00, inclusive. The aforesaid represents various different forms .40 or outlines of a jamb unit having a single wing extension arranged for overlapping a wall at an opening and providing a structural unit at the wall opening for ?nishing the same. In Fig. 7 there is illustrated a modi?ed form of 45 the invention. In this form of the invention the unit is shown in a reversed arrangement—that is, the detachable portion is shown at the lower left hand corner of the ?gure, whereas in Figs. 1 to 6, inclusive, the detachable portion is shown in the upper left hand corner of the ?gure. It will be quite apparent that mere reversal of the units shown in Figs. 1 and 2 would approximate the showing of the positionof the unit shown in Fig. '7. Fig. 7 illustrates two features that may be in corporated with equal facility in any one of the units shown in Figs. 1 to 6, inclusive. In Fig. 7, by the numeral I'III‘a, lies in a plane slightly in front of or in some instances coincident with the plane of the front face of the overhanging wall I05, said face being designated by the numeral I05a. Thus, Fig. 7 shows a still further modi?ed form of the invention. Also, as indicated at IIlI ', the two walls I02 and IOI instead of meeting in a square corner, may have a rounded surface connection. As a further modi?cation of the invention, 10 which may be included also in any one of the units shown in Figs. 1 to 6, inclusive, the wall I03 may be united to wall I05 by a reduced por tion IE8’ and similarly wall I04 may be united to wall I02 by a reduced portion I09’. In other words, this modi?ed form of the invention illus trates broadly a succession of L-shaped detach able portions similarly associated in the unit. The unit shown in Fig. "I, while suitable for use as a jamb unit whenever the space is insufficient 520 to permit the utilization of the tubular forma tion, is primarily a sill unit. As heretofore stated, the units shown in Figs. 1 to 6 inclusive, are primarily jamb units. Fig. 3 illustrates a unit which may be used £25 as a plinth block. For internal ccrners or cove units, in order that a complete disclosure of the entire system may be set forth, there has been illustrated in vFig. 8 such a unit and for production purposes 30 and reduced handling and also to reduce break age, the internal corner or cove unit is preferably made double. The main wall is indicated by the numeral III has a concave, ?nished surface contour II2 with ornamentation I I8 at each end. 35 The back wall portion is indicated by the numeral H3 and an extension IIII projects therefrom. Suitable recesses or passages ill for doweling are also provided. rI‘he two portions I Ir'i as united by reduced portions H6 and the two adjacent portions of the meeting walls III are united by the reduced portion M5. Thus the two units are positioned back to back and are tied together like the Siamese twins by the reduced portions I I5 and IIS and are readily separable by the use 45 of a trowel or other suitable instrument. In each of Figs. 9 and 10, there is illustrated a two-wall corner unit of external or convex type. In Fig. 9 the numeral III} indicates the rounded corner wall which at the ends is pro vided with dowel recesses or openings I21. Pro jecting laterally from each end of the curved or suitably contoured wall I I9, is a ?nished Wall or wing extension I201; and an oppositely directed ?nished wall or wing extension I202). Extending 55 towards each other from each of the junctions of the numerals beginning with IN and terminating said wings with the curved corner portion I I9, are with IIO represent like or similar parts similar to the same parts similarly designated by con la0 secutive numerals 4| to I00 in Figs. 1 to 6, inclu the walls I280. and 62873‘ which are united together sive, respectively. In other words, I05 and I0‘! represent an L-shaped portion united by the re duced portions I08 and I09 to the overlapping wing extension I05 and the back wall I04, re ; spectively. Wall I03 together with wall I02 form with wall WI and wall I04, the tubular body struc ture. Wall I02 and wall IIII constitute the ex posed surfaces. The overlapping wall or wing extension in shown at I05. In this form of the invention, however, there is a distinct reversal. Heretofore, the overlapping wall has been shown positioned so that its rear face lies in a plane ahead of the ?nished face of the tubular portion. In the present form of the 7.5. invention, the rear wall of portion IOI, designated 50 at I24. Suitably secured to the portion I24 at I23 and 60 suitably secured to the overlapping wing wall I200. at I23, is an L-shaped structure having, the wall portion IZIa and I22a associated with the wall I28a and the wall portion IZIbI and IN?) is similarly associated with the wall I201). 65 The dotted lines indicated at I25 in Fig. 9 represent a central or partition wall which may be utilized whenever desired. It extends from wall I24 to wall He. Also, if, as and when desired, the walls I28a 70 and I28b may be associated with the junction of walls I20a and the adjacent corner of wall “9 and wall I20b with the adjacent‘corner of wall H9 by the reduced portions I25aI and I251); re spectively. 785 4 10 15' 20 25 2,036,131 The unit shown in Fig. 9 embodying the cen tral wall I25 and having the two L-shaped por tions removed, is shown at 203 in Fig. 17 and is illustrated in elevation in Fig. 16. In Fig. 10 a slightly modi?ed form of the inven tion shown in Fig. 9 is illustrated. In this form of the invention, I29 indicates the curved corner wall at the ends of which may be provided the recessing or passages I37 for dowel reception and from the opposite ends of corner wall I29 project the overlapping walls or wing extensions I30a and I 305. Extending towards each other from said connections, are the walls I38a and I381) united together at portion I34. Extending across from portion I34 to wall I29, there may be pro vided an intermediate central wall I35, shown dotted. If desired, walls I33CL and I38b may be connected to walls IBM and I301) by the reduced portions I35, shown dotted, if, as and when desired. Extending towards each other from the ends of each of the‘ overlapping portions I390, and I361) are the walls I 3i a and I3Ib, respectively, associ ated together by the reduced portions I33. A continuation of each of said walls is indicated at I32a and I321), respectively, and the same are as sociated with walls I 33a and I331), respectively, at the junction I34 by the reduced portions I33. In this form of the invention, the readily detachable 30 portion I3Ia and I32a or I3Ib and I32b are of angular formation, as distinguished from the right angular or L-shaped form heretofore illus trated in all of the ?rst nine ?gures, excluding Fig. 8. Broadly, therefore, the invention con templates the formation of the readily detach able portion of angular outline and as a speci?c form of the invention, such angularity is L shaped. In certain types of production, the cor ner unit with the angle arrangement shown in Fig. 10 will lend itself to more rapid and less expensive production than the form of the unit shown in Fig. 9. Whenever additional architectural ornamenta tion is desired, as for paneling and border work, a 45 duplication, as it were, of units I to 6 may be em ployed and herein two forms of such duplication are illustrated in Figs. 11 and 12. The unit shown in Fig. 11 includes primarily a front wall I49, 2. back wall I54, and two side walls I58a and I581). said walls being provided at suitable positions with recesses or passages I5'I for the reception of doweling, or the like. If desired, wall I581) may be connected to wall I49 by the reduced portion I56a and when so connected, the wall I54 is con 55 nected to the central wall I55 interposed ‘between wall I54 and Wall I49 by the reduced por tion I56b. Each of said walls I580. and I581) may be thus connected if, as and when desired. Extending laterally from wall I49 and at each end of said wall, are the walls or Wing exten sions I50a and I551). The back face of wall I5Ila or I561) as illustrated in Fig. 11, lies in a plane slightly in front of the front face of wall I49. The end of each wall I59 of the respective sub scripts, is connected to one end of an L-shaped readily detachable portion, including the wall I5I of the same subscript and the wall I52 of the same subscript. The reduced connection I53 70. connects the last mentioned wall to the wall I58 of the same subscript. The unit shown in Fig. 11 is of the reentrant type. It is similar in a way to the unit shown in Fig. 7 but constitutes, as it were, a duplication , of the same. As previously set forth, when thus constructed it includes four readily detachable L shaped sections. The unit shown in Fig. 11 is similar to the unit shown in Fig. 13, in that the L shaped portions which are detachable, are oppo sitely directed and in that respect the unit shown in Fig. 11 is similar to Figs. 9 and 10 but as re s'pects the two successive L-shaped portions, which are similarly directed, Fig. 11 is compa rable to the unit in Fig. 7 and of the modi?ed form thereof and is similar also to the unit shown 10 in Figs. 14, 15 and 16, which show the successive arrangement of a plurality of L-shaped detach able portions. In Fig. 12 a modi?ed form of the unit is illus trated. This also is of the reentrant type, al 15 though it will be readily understood it may be of the opposite type. The wall I39 is connected at its ends to two parallel walls, I48a and I482), and these are connected at their ends by wall I44 forming a tubular unit. Extending outwardly 20 from each end of wall I39, are the overlapping walls or wing extensions M011 and I4lJb. The rear faces of the walls Mud and I405 lie in a plane slightly ahead or in front of the ?nished surface of wall I39. When the structure is not 25 of the reentrant type, the arrangement of the walls is preferably that as shown in Fig. '7, where in the overlapping wall is offset rearwardly so that its ?nished surface lies somewhere behind the surface of the front wall of the tubular unit 30 and preferably in line with or behind the rear face of the front wall thereof. Each end of the overlapping extension is con nected by a reduced portion I43 to‘ an L-shaped Wall bearing the corresponding numeral sub 35 scripts. Thus wall I40a is connected to the wall I44 at the junction of the wall I48a by the re duced portion I43 and the angularly arranged portions I4Ia and I42a. Similarly, wall M01) is connected by an L-shaped structure bearing‘ sim ilar numerals with the subscript “b”. It will be apparent from the comparison of Figs. 11 and 12, that Fig. 12 is a simpler unit, in that it only illustrates two L-shaped removable portions op positely directed and it includes a tubular struc 45 ture with two diverging wings which are in sub stantial alignment. In this respect, unit I2 is similar to Figs. 9 and 10, except the two overlap ping wings of the units in Figs. 9 and 10 extend angularly of each other. Fig. 11 differs from Fig. 12 in that the tubular portion, instead of being a single unit, as shown in Fig. 12, is of a double unit type with the cen tral partition wall and in this manner broadly conforms to the original disclosure in Figs. 9 and 55 10, wherein the wall I25 and wall I35, respec tively, are comparable to‘ wall I55. However, in this form the two overlapping wings are in align ment with each other, whereas in Figs. 9 and 10 they are angular of each other. However, Fig. 11, 60 as stated, includes two successive L-shaped de tachable portions and two oppositely directed L shaped portions as well. Figs. 9 and 10 do not show anything more than two oppositely directed L-shaped portions or two oppositely directed 65 angular portions, respectively, with which may be associated a substantially v-shaped portion that is readily detachable, as shown dotted therein. While in Figs. 9 and 10, the wing walls are shown of equal length as to the extension and as 70 of similar contour in each wing, the wings of either of said forms may be of unequal length and also to dissimilar outline. Also, the units shown in Figs. 11 and 12 may be similarly modi?ed. 76 2,036,131 The‘ brick manufacturer only makes full length and half brick. The facing tile manufacturer makes short lengths of the 12” unit, to wit, 4", 6", 8" and 10”‘ short length units. The overlap ac commodation, of the invention therefore, is suffi tachable L-shaped portions and in that respect particularly, said units correspond to the modif ?ed forms shown by full and dotted lines in. Figs. 7, 9, 10 and 11. cient‘to cover any variation of length of span and the same general outline so that for exterior‘ pur utilize the closest length without cutting the lat poses and architectural ornamentation, they all‘~ ter. Probably the biggest ?eld of the invention for are the same. 10 the present is for single face wall or veneer con struction, and the overlap is bonded to the end and a portion of the face by a mortar joint which insures perfect plumbness in the ornamentation in spite of slight variation or irregularity in the 15 contour of wall units proper. The provision of spacing for a mortar joint between the overlapping portion and'the over lapped face of the wall provides for the aforesaid accommodation. The projection of the end of the overlap is 20 sufficient to cover a projection from a wall of such standard brick and facing tile units, as the “sani tary cove” and the ogee Wainscot cap, and, therefore, these units may be used in conjunction with the units embodying this invention, without the necessity of using the many various hand molded closures heretofore necessitated. Unit 255 is clearly illustrated in Fig. 13 and it will be noted that Fig. 13 illustrates a further modified‘ form of the general arrangement shown in. Figs. 1a to‘ 6, and Fig. 7. It will be noted that in‘ Figs. 1: to 7 but one L-shaped portion is de tachable, while in Fig. 7 in the modi?ed form, two L-shaped portions are detachable, leaving but two 35K exposed walls. In Fig. 13, the unit has two L slraped portions which are readily detachable and a central or partition wall projecting rearwardly from the main wall body portion and interme diate'the ends. In Fig; 13, the exposed wall portion is indi cated by'the numeral 291 and the transverse wall is ‘indicated’ by the numeral 289. The corner is shown rounded and in that respect is similar to. the modi?cation indicated at HM’ in Fig. 7. ‘Extending parallel to the wall 29!] and of greater length and at the opposite end of the portion 291‘, is a wall 293. Extending oppositely from the wall 29! and from the wall 293 is the wall portion 292. In this form of the invention also, 501 the. front face 292a cf portion 292 lies behind the 40." rear face, 229m of portion 28!, and in this par ticular also this unit is similar to the unit shown in Fig. 7. The walls 2% and 293 are united by L-shaped readily detachable portions 29419 and 29152) by the reduced portions 29% and 2911), respectively, the latter constituting the reduc tions in said walls to facilitate ready and prede termined detachment. Similarly, Walls 292 and 293 are connected by an L-shaped readily de 60 tachablewall having portions 295a and Etta, the same being attached to said walls by the reduced portions 291a and 296a, respectively. The unit 255 shown in Fig. 13 or one like it, may have the‘ two L-shaped detachable portions removed therefrom‘. In Figs. 14 to 16, inclusive, there is illustrated a unit which is similar in many respects to units shown in Figs. 1 to 7, 9 to 11 and 13. It will be noted in Fig. 13 the two L-shaped portions, or 70: broadly speaking the angular portions, are op positely directed and in that respect, Fig‘. 13 is comparable broadly to Figs. 9 to 12, inclusive. With respect to Figs. 14 to 16, inclusive, these ?gures represent units that have a multiplicity of 75 successively and similarly arranged readily de Figs. 14 to 16 also represent a single unit of For structural purposes, however‘, and for different requirements, they differ, be~ cause while the units have the same overall dl-i 10" mansions as to width and depth and can have the same overall dimension as to length, unless’ full and fractional length units are formed, these units provide different degrees of detachment. In Fig. 14, there are three successive and simi-i larly arranged detachable portions. In Fig. 15 there are four and in Fig. 16 there are five. In Fig. 1a, the numeral 260 indicates the top wall which is ?nished, numeral 263' a wall: ap proximately at right angles thereto, numeral 264' 20 an extension thereof, numeral 2640!. a further extension and numeral 26% a still further exf~ tension. Wall 250 is united to wail 263, in addi tion to the direct connection, by Walls 26! and 252. The junction of walls 262 and 26! is united to the wall 264 by the L-shaped portions 265 and 266, the connection being by reduced pore tions 261 and 2%, respectively. Successive L shaped portions bearing the subscript “a” andv “b” are similarly united by the reduced por~ tions 261a and 26117, and ‘268a and 2681), re‘ spectively. One or more of the L-shaped portions suc cessively may be detached from the unit. In Fig. 15, wall 2'5!) is positioned similarly to wall 266. Wall 213 is similar to 263 andv walls214, 211411, 21%. and 2140 are continued exten~~ sions of Wall 214 and are similar in outline and‘ total length tov the unit shown in Fig. 14. Walls 2'“ and 212 are similar to walls 26! and 262 40 of Fig. 14. The L-shaped portions 2'15 and 216 are’ united in a similar manner by the reduced Wall portions 211 and 218. Similar L-shaped’ extensions and similar reduced connecting por tions bearing similar numerals with the sub scripts “a”, “b” and “o”, are illustrated. In, Fig. 16, wall 286 is similar to walls 260 and 216' of’ Figs. 14' and 15. Wall 283 is similar to walls 2%‘ and 213 and the extensions 284, 284d, 28%, 2860 and 284d constitute an extension of 50$ the same length and outline as wall portions 264, 261300 and 26th in Fig. 14 and 214, 214a, 2141) and 2M0 in Fig. 15. The connecting walls 28l and 282 complete the permanent portion of the unit and a plurality of successive L-shaped readily 55' detachable portions, herein ?ve in number, are associated therewith. The ?rst of these is indi cated by the numerals 285 and 286 connected by‘ the reduced portions 281 and 288 to the junc tion of walls 281 and 282 and wall 284. Suc-> 60% cessive L-shaped readily detachable portions are similarly positioned and are similarly connected, the several successive portions being designated by similar numerals bearing the successive sub ila77, Mb)!’ ‘(C3, ‘(d,,. In. Fig. 17, there is illustrated a modi?ed and multiple form of the unit shown in Fig. 8 and which embodies the singie wing extension and an L-shaped readily removable portion, and in this respect the unit shown in Fig. 17 is similar to a combination of the disclosures of units illus trated in Figs. '7 and 8. In said Fig. 17, the numeral M2 indicates the finished reentrant sur face of the cove or corner unit, the body por 6 2,036,131 tion being formed by two oppositely directed portions 4H and M3, Extending oppositely from the portion 413, is the wing “4. It is not ?n ished. The corners of the cove unit may be .?nished either as shown at H8 in Fig. 8 or as illustrated in Fig. 17 and indicated by the numeral M8. The cove units may also have the dowel openings All. The L-shaped portion is indicated by the numerals M9 and 42D and por 10. tion M9 is united to the portion MI by the re_ duced portion 4 I5 adjacent the surface M8, while portion 420 of the L-shaped, readily detachable portion is united to the wing extension 4“ by the reduced portion M6. For manufacturing purposes, this type of cove unit readily lends itself to dual production and when so produced, the portions 413 are united by a readily detach able connecting portion HI and portions 4| 4 adjacent their free ends are similarly united by the readily detachable portion 422. In Figs. 18 to 20, inclusive, a right hand end sill starter unit is illustrated. This unit has the same outline or architectural ornamentation as the sill unit shown in Fig. '7. In Figs. 18 to 20, the front face is indicated by the numeral 5H]. The face 5| l is un?nished and substantially abuts the adjacent sill and (of course, separated by the mortar joint therefrom). The opposite face 5“ suitably merges with face 5| 0 and 5| 2. 30 An L of these units are suitably glazed, if, and when desired, and may be suitably colored so that any desired tint or color may be obtained; further— more, the surface may be any desired texture or ?nish. To illustrate the advantage of the present sys tem in a certain proposed installation, it was esti mated that with the old method of construction for a certain architectural ornamentation, elimi nating entirely the question of increased cost due to exactness of laying, increased cost due to pre cise architectural design and other expenses in cidental thereto, that ?fty-?ve different types of present standard construction units were neces— sary to secure the architectural ornamentation desired and to secure the requisite ?nishing of the several 'walls and openings. However, this same desired construction and ornamentation with the new units embodied therein, required but sixteen different types of new 20 units. The volume of structural work remained substantially the same. It is quite apparent that due to the saving factor in the elimination of breakage, the saving factor in the elimination of cutting and the elimination of special ?tting of 25 the units together, all permitted a much lower price to be quoted for the proposed construction when it was to be built of units of the present invention. shaped portions 5I3--5l4-see Fig. 20,-is pro Furthermore, the present invention has the ad vided at one corner, and herein is shown dotted vantage that the number of units are a minimum having been removed. It is secured by reduced portions 515 and 5H5, respectively, to the main for any given job and are of predetermined lengths, it, of course, being understood that the units may be made in half, full and double lengths. This eliminates the complexity and con 35 body portion. This cutout or corner 5|‘! is pro vided to accommodate the jamb unit. The unit—~ see Fig. l9—also includes the L-shaped readily detachable portion 5l8-5I9 united by the re duced portions 520 and 52I, respectively, to the under the old and standard type of construction, with the predetermined positioning of each piece body portion, having the depending overlapping in an exact location in the architectural design. wing 522 to overlap the upper course of the wall at the opening. It will be apparent from the foregoing descrip tion that the basic form of the ornamental struc tural unit comprises a unit having at least two ?nished faces or the equivalent thereof, and at least one angularly outlined, and usually L is no interchangeability with these ?fty-?ve pieces, as a general rule. With the present con struction there is a considerable range of inter changeability so that should a piece be broken, become lost or be missing, the construction can 45 shaped in outline, readily detachable portion. fusion resulting from the use of ?fty-?ve shapes Furthermore, in the actual construction, there 40 proceed, leaving the gap for that particular piece, Other forms of the invention disclose the utiliza tion of two angularly arranged, readily detach if necessary, and no other duplicate unit is avail able. Furthermore, due to the fact that but sixteen able portions and in some instances, these are different types are required, it is possible to in 50 of L-shaped outline. A further form of the invention contemplates the positioning of the angularly or L-shaped outlined extensions when of plural character, either in succession and similarly directed or op positely directed and in certain instances, both oppositely and successively directed and in cer tain instances in longitudinal alignment and in other instances in angular relation. Each of the 60 units has the fundamental distinction that by re moval of a portion of the same, there is provided a ?nished portion adapted for overlapping pur poses and in most instances, except the multiple attached form in Fig. 13, the form shown in Fig. clude in any bill of material at least one extra piece of each size at a very small cost, whereas with ?fty-?ve different shapes, such a procedure is practically prohibitive. As further evidence of the utilitarian value and 55 the savings that are possible, it is pointed out that for any given construction, there are at the pres ent time, excluding the present invention, three desirable sanitary types of permanent struc tures—?rst, the salt glazed type which includes 60 no, or but little, architectural ornamentation or color ?exibility; second, the terra cotta construc~ tion with all of its advantages, and third, the standard tile structural construction in ceramic 8 and a detached form of the unit, as installed, glazes. The cost of these is as follows: The salt 65 usually includes a tubular type structure. Each of the units may, if desired, be provided with dowel receiving recesses, although they have, for the sake of clearness, been omitted in Figs. 13 to 16, inclusive, although it is to be understood they are usually included therein. The doweling is not illustrated in those ?gures, wherein the sev~ eral units in their structural application are shown glaze is the lowest, the terra cotta usually is the highest, and the ceramic glaze is usually a very on a relatively small scale. It will be quite apparent that the exposed faces close second to the terro cotta. With the present invention, which is especially adapted to the ceramic glaze type, there is ob 70 tained three distinct advantages; all of the ad vantages of ornamentation and color selectivity possible with terra cotta or ceramic glaze and at a price that is very close to the salt glaze con struction, without any ornamentation for a ?n 75 2,036,131 ished wall. Most of this saving is effected in the matter of installing the units in construction of the wall, the speci?c advantages having been set forth hereinbefore. While the invention has been described in great detail in the foregoing speci?cation and various modi?cations thereof have been speci?cally illus trated and described, the aforesaid is not to be considered as restrictive in character nor the sole 10 modi?cations that are possible. The several modi?cations illustrated and described here, as well as others which will readily suggest them selves to persons skilled in the ceramic and ma sonry art, are all considered to be within the 15 broad scope of this invention, reference being had to the appended claims. The invention claimed is: 1. An architectural unit including a body pre senting a plurality of ?nished exterior faces dis 20 posed at angles to each other, a pair of walls integral with and disposed at angles to each other and detachably connected at their ends to said - body, the outer face of one of said walls disposed in the same plane with an exterior ?nished face 25 of said body. 7 2. An architectural unit including a body pre senting a plurality of ?nished exterior faces dis posed at angles to each other, a pair of walls integral with and disposed at angles to each other, the edges of said walls detachably con nected to the rear of exterior ?nished faces of said body. 3. An architectural unit including a body hav ing substantially right angularly disposed ex terior ?nished faces, a pair of Walls disposed at 10 right angles to each other, the ends of said walls detachably connected to the rear of said body so that the outer faces of said Walls are disposed in substantially the same planes as said ?nished faces whereby the unit assumes a substantially 15 rectangular shape in cross section. 4. An architectural unit including a hollow body bounded by walls and assuming a substan tially rectangular shape in cross section, certain adjacent walls of said body having ?nished ex 20 terior faces, and the remaining walls of said unit connected along weakened lines to the interior faces of the ?rst mentioned walls.
