' BUMPER.

Application filed December 18, 1924. Serial No. name.

To all whom it may concern:

Be it known that I, WILLIAM G. Kerr, a citizen of the United States, residing at Oakland, in the county of Alameda and State of 5 California, have invented certain new and useful Improvements in Bumpers, of which the following is a specificatio The present invention relatesto bumpers for automobiles and other likelvehicles.

an improvement in bumpers of the nonhook type, which improvement consists essentially in the particular construction of the central or main contact bar and the mounting brackets extending therefrom, and also consists in the formation of the nonhook ends and their manner of attachment to the ends of the main bar, whereb a stronger and more efiicient bumper of t is type is provided.

With the above mentioned and other ob 'jects in view, the invention consists in the novel construction and combination of parts hereinafter described and illustrated in the accompanying drawings and pointed out in $5 the claims hereto appended, it being understood that various changes in form, propor-v tion, size and minor details of construction may be resorted to without departing from the spirit'or sacrificing any of the advan- 3 t es of the invention.

0 more fully comprehend the invention, reference is directed to the accompanying drawings, wherein- Figure 1 is a fragmental plan view of the i front end of an automobile showing the bumper attached thereto.

Figure 2 is a fragmental plan view enlarged showin one of the hinged members, in art only, t e rear face being omitted.

igure 3 is a vertical sectionalview taken inthe direction of the arrows on line 3-3 of Figure 2.

In the drawings, wherein like characters of reference designate 7 corresponding parts, '1 indicates the central melhber of the bumper, constructed preferably of flat strap material, the ends 2 of which are turned backward and form a meansof securing the cantI al member 1 to-the frame horns 3 of the chassis of an automobile by means of the bolts 4' or other suitable attachiniedevices. The outer faces of the rearwardly The object of the invention is to produce forwardly onl nt ends I 2 also form an abutment against which the their front faces 6 being shaped to continue the contour of the front face of the central member 1 theirrear'faces 7 being inclined toward the apex, as shown in Fig. 1, and

their base faces 8 lying parallel with and abutting a ainst the outer faces of the bent ends 2 of t e central member 1.

.The triangular end members 5 are secured to the ends of the central member 1 by means of a spring hinge 9, the tension of the sprin being sufiicient to hold the triangular end members 5 substantially rigid against the abutments formed by the bent ends 2 of the central member 1.

The operation of the end members 5 when struck by an impact from the rear is such that said members will yield forwardly to permit the vehicle to pass the obstruction, thus eliminating any possibility of the bumper being caught and displaced or injure V After the obstruction has passed the end members 5 are returned to their normal position'due to the tension of the springhinge 9.

On the other hand, if the force of impact comes from the front, the same will be met by substantially rigidresistance due to the relatively extensive and solid abutments 2 and 8.

I claim l. A bumper comprising a central member having rearwardl v bent ends adapted for attachment to ave 'cle frame; end members consisting of substantially triangular sections the front faces of which are shaped to continuethe face contour of the central member,their rear faces being inclined forwardly to an a x, and their base faceslymg parallel with and. abutting a ainst the outer faces of the bent ends of t e central memher and a spring hin e connection between said end membersan the ends of the central member located in the line of their front faces, adapting said end -membersto,
