SHOCK-ABSOBBING DEVICE.

A ncatioh area June e, 1923, serial No. 643,693. ,Renewed March 14, 1927. I

The present invention relates to means for cushioningand modifying blows and shocks in all kinds of apparatus and machinery which are subject thereto in the ordinary or extraordinary course of operation. While the invention is applicable to a, great variety of uses, including, for instance, the cushioning of the recoil of guns, etc., it is particularly useful in absorbing the shocks transmitted to the bodies of automobiles'and other vehicles; and,in the following description, the invention is set forth with particular reference to this last named embodiment. I p

In a pending application of lVilliam l. Amory, Serial No. 490,081, filed August 5th,

1921, there is described his discovery that,

by using a hollow rubber cushion capable of supporting the weight of a vehicle while quiescent, and forcing into such cushion a small quantit of air, not only can the action of theor inary springs be supplemented in a manner to prevent the disagreeable long swinging movements which follow from the use of springs alone, but the cushions in question can be usedv as substitutes for such springs, making it possible to suppress their use altogether.

In that embodiment of the present invention herein described, this principle has been taken advantage of, although it is to be understood that certain features of the invention ma be used in combination with resilient e ements other than .that just mentioned. I

The principal object of the present invention is the provision of a form of mounting for a cushioning device ofthe general character above mentioned which is adapted to be applied to vehicle springs arranged in the manner common in the well known Ford car or wherever the shackle operates in ten sion, wherein the chassis rests upon the middle of a spring placed over and parallel with the axle, the ends of said spring being attached just over the axle by means of short shackles.

In the case of a spring mounting of this character there is notenough room between the points of attachment ofeach shackle to insert a cushioning device. 011 the other hand there is ample vacant space over each end of the spring and under the car body, and one object of the present invention is to provide a form of mounting which, while either in connection with springs, or attached to rigid members as a substitute for springs. I do not limitmyself to its use in the preferred manner herein shown and described.

In the accompanying drawings,Figure 1 is a side elevation of the cushioning device proper which is preferably used, Figure 2 i is a plan viewthereof, and Figure 3 is a side elevation of the preferred mounting as applied to one end of a Ford spring and ax e.

In Figuresl and 2, a pneumatic cushion, preferably offlat lenticular form, is shown at 10, with the usual air inlet nipple at 11. This cushion is confined between what I term compression plates, 12 and 13, which are in direct contact with-the two circular faces of the cushion; and outside of the compressionplates are the

transmission plates

14 and 15 which lie flat upon the compression plates. The plates14 and 15 are preferably narrower in one direction than the other, and the longer dimension in one preferably lies at right angles to that of the other. In Figure 2 the transmission plate 14: is shown in.

full lines, while the dotted lines indicate the outline and positionof the plates15 on the under side.

to each other.

and 17 pass downward through the upper transmission plate 14:, the upper compression plate 12, and the lower compression plate 13, in that order. The heads 18, at the upper ends of these bolts, and the nuts 19 at their lower ends serve to hold the plates named in the positions shown in Figure 1; that is to say with the

plates

12 and 13 held fiat against the cushion 10, and with the plate 14 in contact with the upper surface of the plate 12. At the same time, since the

bolts

16 and 17 are free to slide in the holes in the various plates, it is clear that the

plates

12 and 14 may be freely moved toward the plate 13 to compress the cushion 10.

In the same manner and with the same eiiect,

bolts

20 and 21 pass upward through the lower transmission plate 15, the lower From this it will be seen that these plates lie substantially at rightangles compression plate 18 and the upper com: pression plate" 12, in the order named. The

heads 22 and the nuts 23 on these bolts-holdthe. plates together in the same manneras the heads18 and 19..

In order to attach the cushioning devlce to the relatively movable members thirougl-i.v

which any shocl; is transmitted, each transmission plate is provlded wlth a pair otears,

those on the upper plate being shown at 24' and those on the lower plate at 25.

plates

14 and 12 which: again press the cushion 1-0 against-the plate 13. The second movement, or downward blow, is again cushioned bv the elementlO in the same manner.

What is claimed. is

In apparatus for the purposes described, a cushioning device comprising a. cushion unconfined at its periphery, compression plates-thereon, transmission plates outside of said compression plates. and slidable bolts uniting eachtransmission plate with the opposite compression. plate, incombination with a pair of transmission levers united; by a pivotal joint and having their ends on one side of said joint pivotally secured. to the respective transmission plates of" said cushioning device.
