with» the accompanying drawing, Sets forth the‘
preferred embodiment of the invention
Referring to the drawing in which a preferred
embediment 0f the invention is illustrated
Figure 1 is e Perspective View, partially in Sec
tion, through a wall construction embodying me—
tallic sheathing and supporting members there- 20
for. In this ?gure several forms of application
are illustrated.
With the economic developments of sheet and
extruded aluminum stock, .stainles steel and
vitreous enameled products it has been found
feasible to employ such materials in building construction as a sheathing medium for both interior
10 andexterior wall surfaces. In the development
15 the frame of the building structure. In such constmction it has been found dif?cult during e'rection to maintain the assembly tolerances necessary to assure uniform securement of the panels
upon' the supports. In fact in many instances it
20 was found that the anchorage of the sheathing
was inadequate to withstand wind pressure in
certain portions of the construction, while in
other areas of the same construction the plates
had been distorted under the compressive effort
25 necessary to snap the ?anged edges of the plates
upon their keepers during assembly.
The improvements embodying the present invention contemplate certain re?nements in the
supporting structure and sheathing plates which
30 in addition to obviating the foregoing objections,
facilitates the production of more rigid structure,
an assembly of superior msthetic appearance
and an organization which will accommodate the
support of structural forms of building mate35 rials other than the aforesaid sheathing members.
Among the various objects of the invention the
present improvements comprehend a retention
strip which is formed to effect tensional strain

A further object of the invention is to provide
45 a supporting rail which is adapted to accommodate the retention of a glass plate or similar
panel without structural modi?cation of said rail
section, of another modi?ed form of glass plate
As illustrated in Figures 1 and '7 the metallic
sheathing I0 comprises rectangular pressed metal
and which moreover is formed to accommodate . panels having marginal ?anges H, the edges

50 the opposed face of the glass in the same manner
as that employed to secure the metallic sheathing.
Another object of the invention is to construct
a sheathing supporting rail which is adapted to
thereof being ?ared‘ outwardly at suitable angles
for engagement upon the faces of a channel or 50
groove l2 in the supporting rail l3. The rails
i 3 are adapted to be secured upon the vertical
or transverse frame members of a building struc
ture, as for instance, upon the angle iron or purlin
55 accommodate the ready assembly of such rail
strips l6 shown in Figure 1. Although the frame 55
' 2
members shown herein are disposed in transverse
position it is to be understood that any of the
conventional forms of framing or an uninter
rupted wall surface will accommodate the sup
port of the sheathing supports or rails it.
The supporting rail is preferably formed of
extruded aluminum bars and comprises in detail
‘a pair of opposed ?anges i5, the upper faces
whereof are slightly inclined‘ inwardly in order
10 to compress the
glnal edges of paneled heat
insulating material it disposed between the
sheathing it and said faces of the ?anges i5;
Intermediate the ?anges it there is a pair of
ribs i1, theiree ends of the inner faces thereof
being formed with arcuate faces to accommodate
irregularities in the corners between the sheath
ing and the ?anged portions ii thereof. The
con?guration of the rail intermediate the ribs
5 ‘i which constitutes the groove 5 2 is formed with
20 converging faces disposed at suitable angles to re
ceive the outwardly ?ared edges of the sheathing
plates it. The outer faces of the ribs ill con
verge slightly toward the base of the strip and
‘are formed with grooves it throughout their
25 length which, as illustrated in Figures 1 and 5,
provide a chamber for the reception of putty or
caulking material within which the glass plate
is is set. The lower faces of the ?anges it are
formed with grooves or scores ‘2d disposed in
30 aligned relation with the outer walls of the ribs
ll provided to serve as guides in shearing or cut
ting portions of the ?anges it from the rails,
which, in assembly, would interfere with con
tiguous ?anges of appurtenant members. The
35 lower faces oi the rail E5 is recessed to accom
construction is illustrated in Figure 4, where, as
indicated, the ribs i ‘l of the transversely disposed
rail is notched to permit the entry of the corner‘
portions of the ?anges H oi’ the sheathing. In
assembly, in order to provide a more rigid struc
ture, the molding strip 2| is preferably positioned
within the grooves i2 of the abutting members
and extended through the notched portion of the
unbroken rail.
Inthe lower portion of Figure '1 an alternate
glass supporting medium is illustrated. In this
embodiment the molding 2i is adjusted so that
the ribs 25 will abut the glass '30 and the outer
edge of one of the ribs ll of the supporting rail
i3. Putty or other suitable caulking. material
may be applied coincident the application of the
molding strip and the strip may be anchored upon
the supporting rail by machine screws or other
suitable locking devices. Should it be desired
to provide a water shed or drip plate above the 20
glazed opening such member may be readily re
tained by forming the inner ?ange thereof to
conform to the angular face of the groove 82 in
the supporting rail and assembling the molding
to effectuate the'retention thereof in the same 25
manner as the sheathing. In structures having
large. glazed areas muntln strips til may be
employed which, ‘as illustrated in Figure 8, com
prise a ?anged base portion at with a. longitudinal
rib 62 extended upwardly therefrom. ‘The glass 30

groove it of the supporting members by a mold
ing strip 26 which likewise is preferably formed
of extruded aluminum and embodies a cylindrical
body portion 22, having a concave upper face 23
and a ‘?attened base portion 2%. The molding is
also provided-with opposed ribs ‘25, which, as il
lustrated in Figures 1, 5 and 6, are arranged for
intimate engagement with the ?anges ii of the
sheathing plates and preferably adapted to lie

the molding strips to facilitate transverse move

ing sections and above the molding are ?lled with
caulking material of any of the well known types.
It will be noted that as the screws for retaining
the molding strips are drawn in place the arcuate 65
surfaces ‘22 of the molding will draw the outwardly
bent ?anges i i of the sheathing into intimate en
gagement with the angular surfaces of the grooves

tween the sheathing plates and the supporting
members. Moreover, the ribs 25 of the molding
strip, when drawn to seated position, will snugly
engage the ?anges ii and overcome any warped
or longitudinal irregularities therein which would
tend to hold such distorted portion of the ?ange
away from its seated engagement with the rail.
It will be noted .that the inwardly inclined faces
of the ?anges i5 and the ribs ll provide adequate
