My invention relates to bumpers. It is the object of my invention to provide a shock absorbin supporting plate and a buffer plate or p ates forming a relatively broad surface in a single unitary structure. It is my object to provide such a structure ina vcheap and economical manner, eliminating vertical joining and'supporting members which are customary to use, to prevent rattling and to lend strength to the structure. lt is my object, by eliminating such members, to not only reduce the expense, but to increase the strength of the composite structure, to improve the appearance and to eliminate duplicate parts as well as to facilitate the finishing of the bumper.

Heretofore it has been the practive to provide a back bar member and front buer plates joined together by bolts with vertically 2o disposed attaching plates for connecting the buffer bars together to prevent their rattling and to insure their adequate assembly into a composite structure. rlhis necessitated a large number of parts which were apt to become loose and rattle, or which did not furnish the strength without increasing the size of the parts which in turn increased the expense. It'also necessitated finishing of the bumper in a complicated and expensive way and detracted from the stream line appearance and the relinement of design of an automobile, and these supplemental structures provided ornaments that were frequently out of harmony with automobile design.

It is my object to provide the back bar supporting member in such a manner that it may be easily, permanently and rigidly attached to the front buffer bars and so that it will serve as a connecting member between the bars without the use of bolts, clamps and other equipment.

Referring to the drawings# Figure 1 is a perspective from the rea of the bumper struc-ture showing it in assembled condition.

Figure 2 is an enlarged rear elevation of one end of the buffer bars and supporting bar.

Figure 3 is a section on the line 3--3 of Figure 1 through the center of the bars.

Figure 4 is a rear perspective showing a modified form of attaching the bars to one another.

Figure 5 is a view similar to Figure 2.

Figure 6 is a section on the line 6 6 oi Figure 4.

Referring to the drawings in detail, 1 and 2 represent front bumper bars having an interndiate flat portion andi curved ends 3 an Within these curved ends and overlap ing such ends, forming a connecting me um there between, is a rearwardly bent plate 5 constituting one end of the supporting bar 6, which has portion 7 for attachment to the vehicle frame. These ends 5 are welded at 8 to the inner surface of the curved ends of the bumper bars 3.

I have provided a cut away section 9 in this plate 5 so that this cut away portion 9 may overlap as at 10 portions of the inner surface of the ends 3 of the bumper bars 1 and 2 This overlapping space is used in aream which material 11 is inserted for welding the plate 5 to the respective bars 1 and 2. A tti This supporting bar 6 extends from the plate 5 rearwardly as at 12 until it arrives at the flat late'7 on which a suitable clamp is mounted or attaching to the vehicle chassis. It then extends forwardly as indicated by the portion 13 to the center of the structure where it joins a similar portion 13 through the medium of an intermediate plate 14 that 1s parallel to the bumper bars 1 and 2 and overlaps partially the inner central walls thereof on the rear side thereof so that the plate 14E can be welded as at 15 to these bars 1 and 2. A central aperture 16 is provided in this plate 14 for facilitating welding as at 17. These welds 15Y and 17 provide shoulders for engaging either side of the plate 14: so that a rigid, firm and neat structure is provided.

It will be noticed that by this construction I have provided a' buffer of great strength and resiliency due to the fact that the bumper bars are arched from points of attachment to points of attachment, that is, from the center to the ends, and as the ends of the bumper bars are arcuate, this provides a resilient bridge structure for absorbing shock.

Likewise, the su porting bar 6 has orwardly extending diverging arms 12 and 13 to lform a spaced, truss-like structure with the bumper bars so that the free ends thereof may adequately take the shock.

It is to be understood that I desire to comprehend within my invention such modifications as may be desirable within the scope un of my claims to adapt the invention to varyin conditions of use.

laving thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is: v

1. In a bumper spaced bumper bars and a supporting bar ada ted to overlap the space between the bumper ars and join said bumper bars, being attached thereto at each end and the center. A l

2. In a bumper, spaced bumper bars and a supportin bar adapted to overlap the space between t e bumper bars and join said bumper bars, being attached thereto and formed integrally therewith at each end and the center.

3. In a bumper, spaced bumper bars and a supporting bar adapted to overlap the space between the bumper bars and join said bumper bars, being attached thereto and formed integrally therewith by Welding at each end and the center.

4. ln abumper, spaced bumper bars and a supporting bar adapted to overlap the space between the bumper bars and join said bumper bars, -being attached thereto and formed integrally therewith .by welding on the sides and face of the supporting bar against the rear walls of the bumper bars.

5. ln a bumper, a plurality of vertically disposed spaced bumper bars and a supporting bar having its ends and intermediate portion attached thereto inoverlapping relationship to space said bars and connect them to the supporting bar.

6. ln a bumper, a plurality of vertically disposed spaced bumper bars and a supporting bar having its ends and intermediate portion attached thereto in overlapping relationship to space said bars and connect them to the supporting bar, said supporting bar and bumper bars being welded to one another at their points of attachment to form an integral structure.

7. lin a bumper, a plurality of vertically disposed spaced bumper bars and a supporting bar having its ends and intermediate portion attached thereto in overlapping relationship to space said bars and connect them to the supporting bar, said supporting bar and bumper bars being welded to one another at their points of attachment to form an integral structure and the ends of the bumper bars being curved backwardly.

8. ln a bumper, a plurality of vertically disposed spaced bumper bars and a supporting bar having its ends and intermediate ortion attached thereto in overlapping relationship to space said bars and connect them to the supporting bar, said supporting bar and bumper bars being welded to one another at their points of attachment to form an integral structure the ends of the bumper bars being curved backwardly and the intermediate portions -between the central and end` attachment betweenthe supporting bar and bumper bars being spaced from one another, said bumper bars being attached to a vehicle adjacent to the points of maximum spacing.

9. In a bumper, a supporting bar and spaced bumper bars, saidf supporting `bar adapted to support and space the bumper bars being mounted in overlapping relationship on the spaced bumper bars, said support` ing bar having an aperture bridging the space between the bumper bars and overlapping a portion of the inner surfaces of the bumper bars, and welds in said space overlapping the rear of the bumper bars.

10. In a bumper,la supporting bar and spaced bumper bars, said supporting bar adapted to support and space the bumper bars being mounted in overlapping relationship, on the spaced bumper bars, said supporting bar having an aperture bridging the space between the bumper bars and overlapping a portion of the inner surfaces of the bumper bars, and welds in said space overlapping the rear of the bumper bars, and welds on the outside of said supporting bar engaging the rear surface of the bumper bars.

11. ln a bumper, a plurality of bumper bars and a supporting bar having its ends overlapping the rear faces of the bumper bars at the ends, the center thereof and welds on either side of a juncture between the supporting bar and the inner surfaces of the bumper bars.

l2. In a bumper, a plurality of bumper bars and a supporting bar having its ends` overlapping the rear faces of the bumper bars at the ends, the center thereof and welds on either side of a juncture between the supporting bar and the inner surface of the bumper bar, and additional welds in apertures provided within said supporting bar where the apertures overlap the inner surface of the bumper bars.

in testimony whereof l affix my signature.

EDWARD H. MCCLOUD.
