To all whom it may concern:

Be it known that I, J OHN A. JACKSON, a citizen vof the United States ofY America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in DraftRigging, of which the following is a Specification, reference being had therein to the accompanying drawings.

It is desirable that the thrust and pull of the couplers of a car be ,carried to its main or longitudinal sills in a direct line and be distributed among them as evenly as possible. It is alsopreferable that any yshocks or strains in excess of the capacity of the shocleabsorbing appliances in the draft rigging be conveyed likewise to the members of the frame by a rigid, continuous or solid connection. It is further an advantage if the absorption Or cushioning members, usually springs, be under the same direction of strain, `either pulling o1' buiing, and be v all acted on simultaneously.

This invention relates toa draft rigging wherein .the shock .absorbing or cushioning members are under compression, either in pulling, or. in bu'liing, and whereby all strains or shocks are carried directly to the body bolster, and thus distributed evenly to the main sills, andwhereby substantially continuous and rigid connections both for pnlliii or for buiing are provided for transinitting strains or shocks above the vcapacity of the shock absorbers. i

This invention Consists in the matters hereinafter set forth, and m'ore'particularly pointed out in the appended claims.

In the drawings, Figure l is a view in side elevationl of a draft rigging embodying the invention, with the adjacent portion ofthe `cai." body, nia-in sills and body'bolster. Fig.

Furthermore, the full action of all the springs is obtained both in pulling and buing', and this is done within the same 1i n'1it"-of motion as if only a single spring `were used,`all the springs being brought into Play Simultaneously,

When fully compressed, theV draft rigging presents a substantially continuous solid connection in direct line with-the coupler thrustffrom the coupler to the body bolster so lthat/the latter receives the final'shock and arrests the coupler movement.

When desired the eye bolts 18 may be carried back to the center of the car as indicated'in Fig. l. The draft timbers. are thus relieved of alll buiing strains.,

Obviously, changes in the -construction may be made Without departing from the spirit of theinvention and I do not care to ran limit myself to any particular form or arement of parts.
