BUMPER.
Application led November 2, 1920, Serial 11o. 421,209.. Renewed July 14, 1922. SerialA No. 574,982. l
To all whom it may concer/r1 Be it known that I, EDWARD A. BANsoH- BACH, a citizen of the United States, resid-Y ing at Chicago, in the county ofCook and State 1of Illinois, have invented certain new and useful Improvements in a Bumper, of which they following is a specification.
This invention relates particularly to a fender `or bumper foran automobile, although of course, it may have a more general applica-tion wherever it can be used. The principal object of the invention is to provide a new and improved construction of this kind having several ldiiierent resil- V15 ient-\constructions which are brought into action successively depending upon the intensity of the impact. The invention consists in the novel construction, combination and arrangement of the several parts.
In the accompanying drawing, Fig. 1 is a plan view with parts shown in section of a bumper constructed in accordance with the principles of my inventionFig. 2 is a sectional view of a bumper; Figs. 3 and 4 are plan and side views respectively, of a modllied form; and Figs. 5 and 6 are side and plan views respectively, of a different modification.
Many bumpers now in use are merely in s0 the nature of fenders and have no resilient action; if they are at all resilient they usually have but a single spring action which is all right for a slight impact, but is entirely insuliicient to cushion a harder impact. The prescrit invention is designed and intended to overcome these objections by providing a lurality of springs whose actions are cumuative because they act or are brought into action successively.
In carrying out this invention, a supporting back plate 1 is mounted at the ends of automobile side lframes 2 by means of brackets 3a extending from the top of the front plate 1 to the side frame 2 and brackets 3 .45 at the -bottom of the plate through which the ordinary end bolts 4 extend, and in advance of the plate 1 a front plate 5 is supported by means of bars 6 attached to the inner face thereof and extending slidably so through openings 7 in the back plate 1. The
rear end of each baris preferably ofsettoward and into the channelled side frame andr is slidable through a fixed guide 8 therein with a spring 9 surrounding'this end of the bar and pressing against a projection 10 at a distance from the end of the bar so that the outer plate 5 vis pressed outwardly from the back plate 1.A
Intel-posed between the front and back plates 1 and 5 are a plurality of coil springs 11 whichv are graduated in diameter from one end to the other so that they will fold compactly inspiral form when compressed. The ends of these springs are attached to the plates or to one of them in any suitable manner, and although only 4 of them are shown, any desired number of such springs may be interposed between the plates.
Supported by thefront plate 5 is a guard member 12 which is bowed outwardly at the center, and has rounded portions 13 at the ends which extend over the rear side of the back plate 1 which projects laterally beyond the side frames 2. Thisv rd member is also of spring material an `is secured to the front plate by means of projecting pins 14 and slots 15 in the guard in order to permit the flattening of the bowed portlon. Interposed between the guard 12 and the 'front plate 5 is a Hat spring 1,6 preferably secured adjacent its center to the front plate 5 and having bowed portions 17 at each side thereofwhich bear against the guard 12 with the extremities bearing against the outer face of the front plate.
It will be apparent that when this bumper is engaged upon impact, the various resilient members act in conjunction to cushion the shock. The springs may be proportioned so that the coil springs 11 will first be compressed, and then if the impact is sulicient, the guard member 12 will be flattened against the front plate which in turn will. g
be opposed by the spring 16. The springs 9 are preferably to assist in returning the supporting bars 6 and the front plate 5 to normal posi-tion, but it is obvious that these springs 9 may also be made of greater resiliency so that they will assist the spiral springs 11 in opposing the compression of the front plate against the rear one. A construction of this kind is illustrated in Figs. 3 .and 4, in which the bar 18 is similar to the supporting bar 6, and in addition, there is a side bar 19 at the outside of the framfe`2 .supported in guides 20 and extending to a extending them for a distance alon pression sprn 21 which is interposed .between one of t e guides 2O and a projectlon 22 from the bar so that the spring will force the bar 19 and consequently the front plate 5 outwardly. This spring 21 may be a heavy and strong spring which will supplement the action of the spiral springs 11 1n a well known manner.
Instead of supporting the front plate of the bumper by means of compression springs 9 and 21, the extremity 23 of the front plate 5 may be rounded behind the rear plate l, as shown in Figs. 5 and 6, corresponding to the rounded extremities 13 of the guard member 12. Each extremity 23 may be connected to a fiat spring 24 which is bent downwardly and then upwardly directly over a front wheel 25 and under a fender 26 therefor with the extremity 27 thereof attached to a fixed support 28 for the tender 26. This rounded front plate construction is also shown in Figs. 3 and 4, but the addition of the flat s ring 24 not onl adds the resilience of the fiat springs 24, ut also it will be observed that the downwardly bent portion 29 of this spring 24 is positioned close to the surface of the wheel 25 so that when the front plate 5 of the bumper is engaged and pressed rearwardly to a predetermined extent, the wheel is engaged by the flat spring 24 which not only adds the resiliency of the wheel in assisting the bumper action, but it also acts as a brake upon the wheel tending to stop the automobile.
ln all of these forms-it will be observed that the action of the different springs are supplementary to the other ones; their effect is the combined effect of all, and their action, by proportioning the strength of the springs, is made successive and cumulative. -By having the two plates forced'apart by the spiral springs 11 with the rounded ends 13 or 23 projecting the extremities of these plates, there is no danger of the interlocking of these bumpers with that of any other car which is so commonly seen in automobile accidents, and there is very little danger that the front of the fender 26 will be engaged when protected by these rounded bumper ends. Furthermore, it will be seen that the wheel of an automobile may be engaged by the round extremities 13 or 23 when the bumper is engaged, in the other forms as well as that shown by Figs. 5 and 6, so that in any case the final action of the bumper adds the resiliency of the tire, after which the bumper acts as a brake upon the Wheel.
By connecting the outer plate to the spring 24 or to the supporting bars 19 not only is this outer plate strengthened and braced against bending up and down, but also theV bars 19 strengthen the side frames 2, andtpxy e frame, a greater leverage is exerted y it upon the outer plate 5. It is obvious that Meana other variations in construction may be made without departing from the spirit and scope of this invention.
