This invention relates to clipsemployed to re tain pens, pencils» andv other articles ofv manu facture againstv displacement from a pocket or other support and the object of the invention is to provide a clip-on the class described formed from plastic material and particularly such ma terials‘ having a- reasonable amount of spring properties and materials which may be molded or die-cast; a further objectibeing to provide means for reinforcing pl'astic clip bodies of’ the charac (or. 24-11) an' angularly'extending‘mounting plate 2|, which passes through a T-shaped‘ aperture 22‘ in the fountain pen cap 23 and. adjacent the end wall 24 of said cap. The plate 2| has a prong 215 formed from the material thereof; which extends into the bore of the cap 23. Theprong 25 force ably enters a thimble shaped. retaining plug‘ 26 upon insertion‘ of this plug into the bore of the cap. With this construction, the‘ necessity to ce ment the plastic clip 20'to the cap 23 is elimi ter described, as well as, including means for nated. It will be‘understood, however, that the retaining such clip bodies-in connection with the cement can also be'used if deemed necessary. caps of fountain pens“ and with these and other In Figs. 3 and 4- of the drawing is shown an other adaptation of the invention-and in this con objects in view; the invention consists-in a de vice of the class-'an‘di for the purpose speci?ed, 15 struction the‘ clip‘ 21 is molded or cast with a channel 28 in the lower surface thereof extend which is simple‘in construction, ef?cient in use, and which is constructed‘ as hereinafter described ing from the point 29 to the point 30 and. in this and claimed. channel is arranged a reinforcing and preferably spring strip 3| which may be retained in posi speci?cation, of which the accompanying drawing 20 tion in any desired manner. For‘example, by ap forms a part, in which-the separate parts of my plying cement to the clip at the ends of the strip improvement are designated.‘ by suitable reference 3|v as indicated at 32. With this construction, the mounting end 33 of the clip becomes substan characters in each of the ‘views, and in which: Fig. 1 is aside .view of‘thecap' of. afountain tially box shaped in ‘form that is to say, it has penfshowinggone. of my" improved caps mounted 25 a closed end wall“, the lower surface 35 of which thereon with part of the. construction broken is curved to ?t the contour of the .cap 36, and away and in section. spaced side walls 31, the lower surfaces 38 of The invention is fully disclosed in the following . Fig. 2 is a sectional detailed view of the crossed which are also fashioned to conform with the end of a lfountain pen cap showing another adap cap 35. With the construction shown in Figs. 3 tation of the invention. 30 and 4, the mounting end 32 will be cemented to Fig. 3 is very similar to Fig. 1 showing another the cap. It will also be apparent that the side form of ‘construction and walls 39 of the clip which extend from the mount Fig. 4 is a partial section on the line 4—4 of ing end 32 to the rounded end 40 conceal the strip Fig. 3. 3| when the lclip is mounted upon the cap. In Fig. 1 of the drawing I have indicated at 35 It will be understood that various types and ID the side elevation of a fountain pen cap and kinds of plastic materials may be employed, that at l I one of my improved plastic clips. One clip is to say, plastics of the moldable type, as well comprises an elongated spring arm portion I2 as, those which can be die-cast, the latter being terminating, at its free end in a rounded knob generally clari?ed as the thermoplastics, cellu I3, engaging the outer wall of the cap l0, and 40 lose acetate being one form of such thermoplas the other mounting end M of the clip has a ‘con ti-cs. With some of these materials, the neces sity of utilizing a reinforcing member is not es caved lower surface l'5 conforming to the curva ture of the outer surface of the cap [0 and ce sential as these materials in themselves have am ple spring properties to perform the desired func mented or otherwise secured thereto arranged longitudinally of the arm I2 and extending into tion. However, the other types of plastics and the mounting end I4, is a spring strip or rod 16. where relatively thin arms are employed in the This rod can be molded or cast as an insert in clips, it will be desirable to include spring rods the clip body I I, or an elongated bore or passage may be formed in the clip and the spring l6 in serted through the open end I‘! of this bore 01'' passage and the open end may be sealed by a or strips as a part of the arm structure and the present illustrations are given to indicate a few plastic plug I8. _ In Fig. 2 of the drawing is shown a slight modi ?cation wherein a rein-forcing member l9 molded of the possible adaptations of the invention where the reinforcement constitutes an integral part of the molding or casting or a part insertable therein.
