CUSHIONINGSPRING SUPPORT FOR VEHICLES,

Specification of Letters atent.

Patented Nov. 9, 1920.

Application filed .Tnly 24, 1919. Serial No. 312,952.

To all whom t may concern Be it known that I, ALrHoNsUs MICHAEL CRUNICAN, a subject of the King of (Jrreat Britain, and resident of the city of London, in the county of Middlesex, in the Province of ntario, Canada, have invented certain new and useful Improvements in Cushioning-Spring Supports for Vehicles, of which the following is a specification.

The object of the invention is to devise a simple construction of resilient support, which may be utilized for cushioning various parts ot a vehicle such as the seat and the like, in such a way that the shook received is distributed evenly so that it is equalized and the supported member carried evenly when under shock producing an even yield and` preventing any teetering oir' the carried member as the shock is absorbed, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Figure l is a side elevation-oi my device showing it interposed between a carrying member and a member to be supported thereby.

Fig. 2 is a plan view of my resilient suport. p Fig, 3 struction.

In the drawings like characters of reference indicate corresponding parts in the various figures.

l indicates the supporting member and 2 a member adapted to be carried by my resilient support 3 and e indicate lever arms set crosswise one or' the other and connected together intermediately of their length by a pivot pin 5, the members 3 and 4 being spaced apart as indicated in Fig. 2. 6 indicates a pin extending inwardly from the lower portion oit the member Ll. 7 indicates a pin extending inward from the lower portion ot' the member 3. 3 indicates a bowed spring which is carried at its ends by the pins 6 and 7 and bows upwardly so as to i'orm a bearing support for the pivot pin 5.

The extreme ends of the members 3 and 4: may be suitably connected to the carrying member l and to the supported member 2 by means of projecting pins 9 operating in slotted brackets l() or by any other suitable means desired.

It will thus be seen that when the vehicle is subjected to jar the members 3 and 4 is a plan view of a modiiied con- Vwill tend to aline themselves one with the other, carrying the pivot pin 5 downwardly and the pins 6 and 7 upwardly thereby producing a cushioning action which will take up the shock produced by the jar.

In Fig. 3, I have shown an alternative form in which two springs are utilized. in this form ll and l2 are the cross members pivotally connected together by a pin 13, which projects laterally from each side of the cross members. 14 indicates a pin, which is secured .in the lower portion of the member ll and l5 indicates a pin which is secured in the lower portion of the member 12. 16 indicates a bowed spring secured to one end of each of the pins la and 15, being bowed upwardly so as to resiliently carry the correspondingly projecting end of the pivot pin 13. The opposite endsof the pins 14 and l5 projecting from the opposite side oi' the cross members carry a bowspring 17 which is bowed upwardly-so as to carry the opposite end of the projecting pivot pin 13.

From this description it will be seen that l have devised a very simple form of cushioning means whereby the various parts of a vehicle may be resiliently carried so as to take up the jar evenly and which acts as a shock absorber distributing the shock equally so that the carried member is held level during the absorption'of the shock.

Vhat I claim as my invention is.

l. A cushioning spring support for vehicles comprising a pair of crossed bar members, a pivot pin connecting the bar members together intermediately of their length, and a bowed spring carried by the lower portions of the crossed members and extending upwardly to form a bearing support for the pivot pin.

2. A cushioning spring support for vehicles comprising a pair of crossed bar members spaced apart, a pivot pin connecting the bar members together intermediately of their length, pins extending inwardly from the lower portions of the bar members at each side of the pivot pin, and a bowed spring carried at its ends by the inwardly projecting pins and extending upwardly to form a bearing support for the pivot pin between the crossed bar members.

3. A' cushioning spring support for vehicles comprising a pair of crossed members pivotaliy connected together intermediate of their length and disposed in spaced re- Q f Leens@ lation, a bowed spring arranged between the members with the intermediate bowed por-V tion of the spring engaging the underside of the pivot and the ends of the Yspring se- 5 cured to the Crossed members'on oppogite sides of the pivot and below the Same.

4t. A cushioning spring support for vehi'ees ,comprising pair of crossed members' pivotally Connected together intermediate of their length and resilient means attached to l0 the lower ends of `said members-providing a Vcushioning support engaging the under side of the pivot connecting the members.
