"Application filed January 2,5192? Serial No. 883,876.

T 0 all cv/zomz't may concern: I

Be it known that I, JOHN Coo'rn, a

citizen of the United States, and resident of- Elizabeth, in the county of Union andfState of New Jersey, have invented certain new and useful Improvements in Bumpers, of which the following is a specification.

This invention involves certain improvements in automobile bumpers, and more particularly to that type in which the main structural-parts are formed of flat spring steel bars or strips each so mounted as to present its wider face in a vertical plane ()ne object of my invention is to provide improved means for connecting a double bar bumper to a resilient support.

A further object is to. provide improved means for mounting-the general type of impact bar shown in my prior Patent 1,441,400 issued January 9, 1923. Other objects and advantages will be pointed out hereinafter, or will be apparent from a consideration of the various forms hereinafter described.

In the accompanying drawings:

Fig. l is a top plan view of a bumper constructed in accordance with my invention.

Fig. 2 is a similar view of a slightly modified form.

Fig. 3 is a front elevation of the bumper shown in Fig. 1. V

Fig. 4 is an end view of the construction shown in Fig. 1.

Fig. 5 is a section on the line 5-5 of Fig. 1. I

Fi 6 is an elevation of. the clamping mem er shown in Fig. 5.

Fig. 7 is a section similar to Fig. 4, but showing a modified form of clamp, and

Figs. 8 to 16 inclusive are plan views of other forms of bumpers showing other forms of supporting means for the impact bar.

The impact member shown in Figs. 1, 3-

and 4 includes two bars having central portions 10 and 11 in substantially the same vertical plane and spaced apart. The terminal portions 12 of one bar are in the same vertical plane as the terminal portions 13 of the other bar, but the twobars cross each other at two points so that the lower terminal portions 13 are integral 'with the upper central portions 10, and the upper terminal portions 12 are integral with the lower central portion 11. The two points at ,which the bars cross are preferabl substantially directly in advance of t e spring.

hornsor chassis frame members A and B of the vehicle. The two bars are secured together at the crossing points in any suitto able manner, as for instance. -by clamps or rivets 14.

For supporting this impact member there is provided a supporting structure preferably formed of substantially the same char- 5 acter of flat spring steel stock as is em-' ployed in making the two bars of the impact member. The supporting structure includes a bar section 15 at each end which extends between the'two superposed terminal portions 12 and 13 of the impact member, and is secured to' said terminal portions by a clamping member which forms one important feature of my invention, and two forms of which are shown in Figs. 5, 6 and t. In. the form shown in Figs. 5 and 6 this clamping means includes a bolt 16 having a slot 17 extending lengthwise thereof from the threaded end 18' nearly to the opposite end 19 which may berounded or provided with any suitable form ofhead. The slot is of a width substantially equal to the thick ness of the bar sections 12, 13 and 15, and the bolt is of such length as to receive these three sections in superposed relationship,

and in the same vertical plane. The bar sections 12, 15 and 13 are preferably spaced by washers 20 which encircle the stud bolt and hold the two side sections 21 and 22 from spreading apart. They thus serve as clamping members as well as spacing members. If desired the bar sections may be made slightly narrower at the points where they are clamped together by the bolts 16 so thatthe total height of the bumper will be substantially equal to the sum of the heights of the three bar sections. As shown in Fig. 5-, the center bar section 15 is cut away slightly at its upper and lower edges to receive the washers 20. In assembling the bumper, the bar sections 12, 15 and 13 are inserted in the slot 17 with the spacing washers and the parts clamped or locked in position by means of a nut 22 secured to the threaded end 18. This nut forces all of the parts toward the closed end of the slot and prevents endwise or other movement of' the bar sections in the slot. A lock nut or looking washer 23 may be employed to bet ters insure the retention of the nut 22. By 1 I means of this clamping construct omith I impact bar j may be detached- .1 from the su porting-means iii-"case ofrep a i r ment, and it is not necessalfy the supportin In 'ig..7

This sup ma in some cases make the bar sections '15 form 'from the clamp 14: to the securing the -'opposite side to that at whichgthe baring an extension 27 integralwith a section sections12 and 13 enter the. clamping bolt., 15 secured to the clamping bolt 16.

In Fig. 12 I have illustrated aconstruction similar to that shown in Fig. 8, except that the rear bar 26 and its extensions 27 are not integral with the bar section 15 which leads to the connecting bolt 16. The bar section 25* which forms the diagonal connection between the attaching bracket 28 and the clamping bolt 16 is integral with the bar section 15. y

In Fig. 13 I have illustrated a construc tion in which the bar section 15 connecting the clamping bolt 16 and the supporting bracket :38 is separate from but riveted to the rear bar 26 and the bar section 31 from the cross over to the supporting bracket is also separate from the rear bar 26" and the bar section 15 The construction shown in Fig. 14 is similar to that shown in F 13 except that the bar section 31 connecting the cross over to the supporting bracket 28 is bowed in the opposite direction, as shown in Figs. 10 and 11, and is integral with the bar section 15% which connects the clamping bolt 16 to the extension 27 of the rear bar.

In Fig. 15 I have shown a construction similar to that shown in Fig. 12, except that the rear bar is omitted and the two ends of the bar which includes the section 15 are directly secured to a supporting bracket 28 of the type shown in Fig. 11. o

In Fig. 16 I have shown a form similar to that shown in Fig. 15, except that the bar sections 15 and 25 are connected to a supporting bracket 28.

Although my improved bar supporting means is intended primarily for use with an impact member having a double cross over, as shown in Fig. 3, it may be employed in connection with a double bar bumper in which there is no cross over. This isparticularly true in such forms'as those shown in Figs. 8, 12, 15 and 16, where the only'support of the impact member is at the clamping bolt 16. In Fig. 15 Ihave indicated such an impact member without the double cross over feature. Even with such forms as those shown in Figs. 1, 2, 9, 10, 11, 13 and 14 where there is a double support for each end portion of the impact member, the support at the point directly in front of the chassis frame members maybe to a cleat connecting the two parallel bars which do not cross over.
