in SPRING CMPANY, OF CLEVELAND, GEH), .l CURPRATIGN QF @E10 Application filed August 22, 192?.

rIhis invention relates to bumpers for automobiles, and has reference particularly to bumpers in which the impact bars are proJ vided with longitudinal grooves for the reception of decorative wires.

One object of the invention is the provision of a clamp for holding such wires in place in their grooves, particularly where the wires do not lie flush with the surface of the bar, and at t-he same time for clamping the bar to hold it against movement in its own plane, that is, upward or downward, the latter result being accomplished exclusively through the wire engaging portions of the clamp plate.

Other objects and features of novelty will appear as l proceed with the description of that embodiment of the invention which, for the purposes of the present application, l have illustrated in the accompanying drawings, in which Figures 1 and 2 are plan and elevational views, respectively, of a bumper embodying my invention.

Figure 3 is a cross sectional view on a larger' scale, the section being taken substantially on the line 3 3 of Figure 2.

Figure l is a front view of the outer clamping plate shown in Figure 3.

Figure 5 is a transverse section taken substantially on the line 5-5 of Figure 2.

Figures 6 and 7 are plan and elevational views, respectively, of a bumper in which is embodied a different form of the invention.

Figure 8 is a section on a larger scale, taken substantially on the line 8-3 of Figure 7.

Figure 9 is a front view of the outer clamping plate shown in Figure 8.

Figure 10 is a rear view of the same plate.

Referring first to Figures 1 to 5 inclusive, l have illustrated the invention as applied to a full bumper having impact bars 10 and 11 spaced apart evenly throughout their length and provided with rebent ends 12. llhese ends are attached to plates 13 of generally triangular shape. A rear bar 111 is also riveted at its ends to the plates 13, whereby a closed loop is formed with a single bar in the rear and two spaced impact bars on the front vor outer side. T his particular arrangement of the bars may be varied considerably Serial No. 214,535.

without departing from the spirit of my invention.

Each of the bars 10 and 11 is provided with one or more longitudinal Grooves 15 extend ing through the length of the bar. The bar itself will ordinarily be painted, enameled or otherwise cheaply finished in a darli color, or in a color to harmonize with the colors of the automobile upon which the bumper is to be used. N ow in order to provide an attrae* tive appearance l mount within the grooves 15 ornamental wires which, in the present in stance, take the form of thin metal strips 16, preferably of a color to contrast with the color of the bars, a nichel plated wire being ornamental and satisfactory for the purpose as a rule. These wires are preferably riveted to the bars at their enc s, as indicated at 17.

Intermediate the points 1'? l provide one or more clamps to assist in retaining the wires 16 in place, three such clamps being the number preferably employed, these clamps having in addition the other usual functions of such clamps. The central clamp comprises an outer plate 18 and an inner plate 19, which plates overlie the opposite surfaces of both impact bars l() and 11 and have aligning open ings through which extends a clamping bolt 2O that also passes through a hole in the bar 14, a nut 21 on the rear of the bolt bearing, through a lock washer 22, on the bach of the bar 14 and serving to draw the parts up into clamping relation. Across the rear surface of the plate 18 there are elongated bosses 23 which entend into the grooves 15 and engage the outer faces of the strips 16. The bosses 23, therefore, serve to retain the wires 16, but in addition they engage the side walls of the grooves 15 and thereby prevent any relative motion of the two bars 10 and 11 either toward or away from each other.

TWhen clamps other than the center' clamp are employed they may be identical with the center clamp except when, as shown in Figures 1 and 2, they do not engage the rear bar of the bumper and in such cases the bolt 2a is shorter than the bolt 20.

In the modification of Figures G to 10 inclusive there are shown impact bars 25 and 26 and a rear bar Q7 similar in general form to the bars 10, 11 and 14E and secured together in the same manner. The bars 25 and 26, however, are provided with one or more grooves 28 of a semi-circular cross section, in which are mounted ornamental wires 29 of circular section, these wires preferably extending around the rebent ends of the bars 25 and 26 and being clamped in place by plates 30 which form the means for attach ment between the ifipact bars and the rear bar 27. The wires 29 may be nickel plated or otherwise finished to contrast with the finishing of the bars themselves.

ln this modification the clamp comprises the same rear plate 19, the same bolt 20, nut 2l and washer 22, but the front plate 3l is formed on its rear surface with substantially semi-circular grooves 32 for embracing the wires 29. `When the nut 2l is drawn up tightly the wires 29 are held securely in the grooves 28 of the bars 25 and 26. At the same time and by the same means these bars are also held against relative movement toward or away from each other, inasmuch as the clamp plate 3l holds the wires and the bars 25 and 26 are immovable with respect vto each other. f

Throughout the foregoing specification and in the appended claims I have employed the term wire in its generally understood commercial sense, that is as applying to a material furnished in coils, regardless of its cross section.

Having thus described my invention what l claim is:

l. In a bumper, a pair of 'impact bars spaced apart vertically, each of said bars having a plurality of longitudinal grooves in the outer surface thereof, a decorative wire mounted in each sai-d groove, said wires being of a cross section different from that of the grooves, clamping means for holding said wires in said grooves, said means comprising a plate overlying the outer surfaces of the two bars, said plate being formed to engage said wires substantially throughoutthe ywidth of the same.

2. ln a bumper, a pair of impact bars spaced apart vertically, each lof said 'bars having a plurality oflongitudinal grooves in the outer surface thereof, a decorative wire mounted in each said groove, said wires being of a cross section different from that ofthe grooves, clamping means for vholding said wires in said grooves, said means comprising a plate overlying the'outer surfaces of the two bars and having an inset portion between the bars, said plate being formed to engage said Wires substantially throughout those portions thereof which are out of contact with the walls of said grooves.

In testimony whereof, I hereunto affix my signature.

GEORGE W. VEALE.
