Aug. 12, 1930; w. J. REINKE WIRE ATTACHING DEVICE Filed Aug. 23, 1928 Patented Aug. 12, 1930 UNITED STATES PATENT OFFICE WALDEMAR REINKE, F CHICAGO, ILLINOIS, ASSIGNOR T0 JUSTRILE MANUFAC- TUBING COMPANY, 013 CHICGO, ILLINOIS, A CORPORATION OF ILLINOIS WIRE-ATTACHNG DEVICE Application filed August 23, 1928.
This invention has for its object to provide a simple, cheap and eflicient device for securing electric wires along the trim of rooms of buildings without injuring the trim or the walls as by driving staples, brads or screws into the same, and which is of such a nature as to permit of its use by unskilled persons to quickly and neatly string lamp-cords and the like in the home along base-boards, under window casings, etc., to thus maintain such cords o1f the floor and out of reach of brooms, Z1PGt sweepcrs, vacuum cleaners and the The invention may be variously embodied and in the accompanying drawings, I have illustrated a plurality of embodimcnts of the same. In the drawings:
Fig. 1 is a fragmentary perspective sectional view showing a Wall and trim go equipped with wire attaching devices constructed in accordance with the invention.
Fig. 2 is a fragmentary Vertical section of the wall and trim shown in Fig. 1 with a device of my invention engaged therebetween.
Fig. 3 is a front elevation of the wire attaching device in its preferred embodiment.
Fig. 4 is a perspective view of the metalfic part of the device.
Fig. 5 is a side elevation of the metalfic part of the same.
Fig. 6 is a front view of an insulation strip employed.
Fig. 7 is a perspective view of a modified form of construction of the device.
In building construction it is the usual practice to apply the wood or metal trim, such as base-boards, door and window casings, picture moulding, etc. after the plastering of the walls has been completed, the said trim overlapping the plastcr and, generally, leaving shallow free spaces between the plaster and the opposed surface of the trim.
Thedevice of this invention is designed to take advantage of this free space by providing a wire engaging substantially semicylindrical member 1 having a shank 2, the latter being adapted for insertion in said free space. Howevcr, in order that said shank may be firmly held in place in said free spac without the use of fastening devis,
Serial No. 301,685.
I provide for a wedge like engagement of said shank betwecn trim and plaster. This, in the structure shown in F igs. 1 t0 5 and 7 inclusive, is obtained by causing the plane of the flat shank 2 t0 intersect the arcuate formation 1 at some distance from its free end. At the latter I provide a flange or lip 3 which bears upon the Wall and slides along the same without scratching or marring the same as the shank 2 is inserted between trim and plaster. During such insertion the shank 2 will be bent as shown in Fig. 2 so as to exert pressure upon the plaster behind the trim and upon the corner of the latter opposed to the plaster, it being understood, of course, that the device is made of a spring metal such as steel, brass or the-like.
By refercnce t0 Fig. 5 it Will be noted that the curved or hook formation 1 of the device is ofiset outwardly from the outer face of the shank 2 and that the lip 3 at outer end of said formation 1 is offset inwardly from the plane of the other or inner face of said shank 2, these faces being termed inner and outer With respect to this position on the Wall or surface against which the lip 3 bears as shown in Figs. 1 and 2. it will also be noted that the shank 2 is devoid of any securing means such as brads, screws and the like.
Obviously, the shank 2 of the device may be bent t0 vary the degree, of offset o f the lip formation 3 from the plane of its inner face to better accommodate the clip t0 engage in spaces varying in width.
It Will be obvious that the recesscs 4 of the shank 2 serve t0 weaken the latter laterally and increase its flexibility at this point. This has been found advantageous aside from the function of said recesscs with respect to retaining the strip 5 of insulation in place, in that, in instances where the crack or space receiving the shank 2 is very small, the insertion of the said shank is less resisted and the flcxing thereof confined alm0st entircly to this weakened portion.
The structure of Fig. 7 is very similar to that of Figs. 1 to 5 inclusive in that the arcuate porton 12 terminates in the fiat shank 13 from which the spring tongue 14: is struck,
the latter being curved bctween its ends and naviflg, preferably, i1ss ree on& opposei to flze upper Wal1 of he slot 15 resulting from the strikin out of the tongue 14 from the shank 13. ad tongue 14 preferaby eztens outwardly from the shank to beau: upon the trim surface opposed to the piaster while its fiat portion beurs on the p1aster.
I daim as my invention A wire engaging clip for e1ectric wre comprising a plane shank devoid of securng means and terminating at one end in a bock formation to receive a wre, said hook formaton being ofiset outwardly from the our face of said shank and termnating in a lip formation ofiset inwardly-from the plane of the inner ace'of said shank.
