IMPROVEMENT IN CAR-TRUCKS.

` Specification forming part of Letters Patent No. 99,77 dated February 15, 1870; reissue No. 5,452, dated June 17, 1873 application filed December 18, 1872.

so arranged in relation to each other that the.

body of the said car when on the truck shall have a longitudinal and transverse freedom of movement, thereby relieving the body of the car from sudden and violent` shocks while in motion, in stopping and starting, as hereinafter more fully described. lIt also has for its obiect the method. of preventing the boxes or pedestals from moving too far out of place in their relation with the frame and axles, and securing of a swing motion. by means of an elastic spring which is interposed between the body and truck of the car, one end of said spring being so secured as to move with the body of the car, while the other end of the same spring is controlled by the truck, allowin g the body and truck of the car to move one independently of the other, as herein set forth.

Figure l is a side view of a car-truck. Fig. 2 is an end view of the same; Fig. 3, a vertical section of some of the details on an enlarged scale; Fig. 4, a perspective view ofthe spring-collar on an enlarged scale.

Like letters of reference refer to like parts in the several views.

A represents the wheels of the truck, connected with the axles, on which rests the axleboxes or housing C. To each end of the boxes C are arms or projections C', having a recess sunk in the arms or projections C', in which rests the bottom of spring D. F is a cap or disk resting on the top of the spring D, and having a liange projecting over the top edge of said spring, and a hub .projecting into the interior of spring D. On the top o f the cap F is placed the spring G on which rests the sill or frame A of the car. The top of cap F may or may not have a fiange to receive the spring Gr.

E are stay-posts, the top of which are fastened rigidly to the sills of the car', the bottom of said posts, being held at right angles to the sill of the carbody by means of the stay-brace H, which brace is fastened to the lower end of saidposts and to the beam or sills of the carbody. The spring G and cap F flt snugly around the posts E, there being play enough, however', to allow them to work up and down easily. In the projection C thereisa hole through which the post E passes, the hole being enough larger than the post to allow the -body of the car to swing freely. Also, in the center of spring D there is a large hole having a space, e, between the spring and the post E, as seen in Fig. 3, which allows the post to move with the car-body, said posts being held in the center'of the top of spring D by means of the cap F.

It will be observed that the top of the spring D is always held in the same relative position with the body of the car by means of the cap F and the posts E, said posts being rigidly fastened to the car-body. Also, that the bottom of the spring D is always held in the same relative position with the journal-bearin g and car-truck by means of the recess in the arms C', there being space to admit a large-amount of play between the post E and the sides of the holes in the arms C', and inthe spring D", and by means of the elastic nature of the spring D the body of the car and the truck can move one independent of the other. By this arrangement ample lateral play is given to secure an easy and comfortable swing motion to the car-body.

It will be observed that the spring 4D and the arms Cl of the axle-box, through which the post passes to the stay-brace H, being' loosely fitted about the post, will, in consequence, allow the frame A" or car-body a longitudinal` and lateral movement, thereby allowing it to sway gently and easily to the varied end and sidewise movements of the wheels, and thus relieve the ear from all violent and sudden shocks while in motion, and in stopping, and starting, and at the Same time the elastic nature of the springs gives to to secure by Letters Patent, is-

the earan easy and gentle support and a spring to its vertical movement. It also permits the car to pass over the curves of thel road with more ease and less strain than cars -of the usual construction.

What I claim as'fmy invention7 and desire 1; The combination of the springs D G and collar F with the arms C', stay-brace H, and post E, the several parts constructed and arranged substantially to operate inthe manner and for the purpose specified.

2.".1he oapor collar F, in combination with 4 substantially set forth.

3. The combination of the post E, cap F, and spring D, the post being connected rigidly with the brace H and frame A, substantially as and for the purpose set forth.
