DRAFT-RIGGING FOR CARS.

SPECIFICATION forming part of Letters Patent N 0. 474,996, dated May 17, 1892. Application filed November 9, 1891. Serial No. 411,278. (No model.)

1'0 all whom it may concern:

Be it known that 1, WILLIAM H. MINER, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvementin Draft-Rigging forCars, of which the following is a specification.

My invention relates to improvements in draft-rigging for freight-cars, and more particularly to certain improvements upon the draft-rigging heretofore patented to me in Letters Patent of the United States No. 464,443, of October 20, 1891.

My present improvement consists in the novel devices and novel combination of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts throughout all the figures, Figure 1 is a plan View of a device embodying my invention. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is a cross-section on line 3 3 of Fig. 1. Fig. 4 is a horizontal section. Fig. 5 is a perspective view of the guide and stop-plate, which is secured to the draft timbers, and Fig. 6 is a face View of the same.

In the drawings, A represents one of the cross-sills of the car-body; B, the draft-timbers; O, the draw-bar; D cl and D d, the tandem-arranged graduated coil-sprin gs, through which the draw-stem 0 passes.

F F F F are the followers, which abut against the ends of the coil springs and through which the draw-stem 0 passes. The draw-stem G fits in a suitable socket c in the end of the draw-bar C, and is secured therein by a strong steel key 0. The squared end a of the draw-bar O abuts against the follower F. A button or collar 0 secured to the draw-- stem 0 or integral therewith between the followers F F abuts against said follower. A

key 0 in the end of the draw -stem abuts against the follower F The followers F F F F are preferably rectangular blocks, and they reciprocate back and forth in suitable guides G G, one secured to each of the draft-timbers B B. The guides are preferably made of malleable iron and cast to the required shape, each guide consisting of a plate lettered G and furnished with-t1] ree integral projections g g g constituting the stops, against which the followers F F F F abut. The guide-plates G have each a web 9 at their upper edges, forming one wall of the guide-recesses in which the followers fit. The lower wall of the guide-recess -is formed by a plate or bar g, which is senotched or recessed at b to receive the guide blocks or plates G. The guide-plate and all the stops on one side for all the followers of the tandem-springs being thus made integrally in one piece, it materially lessens the number of parts and adapts the apparatus to be more conveniently and quicklyapplied to a car, while at the same time the strength and resistance of each stop audits attachment to the draft-timber is increased by that of all' the others.

I claim- 1. In a draft-rigging for railway-cars, the combination, with the draft-timbers B B, of the draw-bar G, secured thereto, draw-stem C, secured to said draw-bar, followers F F F F, tandem-arranged springsDdD d, and guide-plates G, furnished with integral stop projections g g g for said followers to abut against, said guide-plates being secured to said draft-timbers, substantially as specified.

2. In a draft-rigging for railway-cars, the combination, with the draft-timbers B B, of the draw-bar G, draw-stem O, secured to said draw-bar, followers F F F F tandem-arranged springs D d D d, guide-plates G G, furnished with integral stop projections g g g for said followers to abut against, said guide-plates being secured to said draft-timbers, said guide-plates having an upper Web g and a lower guide-bar g bolted thereto, substantially as specified.

3. In a draft-rigging for railway-cars, the combination, with the draft-timbers B B, of the draw-bar O, draw-stem C, secured to said furnished with integral stop projections g g plates being secured to said draft-timbers,

said guide-plates having an upper web 9 and a lower guide-bar g bolted thereto, said stop projections g g g havingholes through them for the bolts to pass through, substantially as specified.

4:. In a draft-rigging for railway-cars, the

combination, with the draft-timbers B B, of

the draw-bar C, draw-stem O, secured to said draw-bar, followers F F F F, tandem-arranged springs D d D d, and guide-plates-G,

g for said followers to abut against, said 1 guide-plates being secured to said draft-timbers, said guide-plates G having hollow proections or bosses g on the back face thereof, through which bolts pass to secure the same to the draft-timbers, substantially as specified. 5. In a draft-rigging for railway-cars, the combination, with the draft-timbers B B, of draw-bar C, having socket 0, stem 0', fitting in said socket in said draw-bar and secured therein by a key, of followers F F F F tandem-arranged springs between said followers F F and F F a collar Q secured to said draw-stein between said followers F F and a key 0 secured to said draw-stem at the end thereof, and stops secured to said draw-timbers for said followers to abut against, substantially as specified.

6. In a draft-rigging for railwey-cars, the cornbination,with the draft-timbers B B, of the draw-bar 0, having socketc, stem 0, fitting in said socket in said draw-bar and secured therein by a key, of followers F F F F ,tandem-arranged springs between said followers F F and F F a collar Gh'securedto said drawstem between said followers F F a key 0 secured to said draw-stem at the end thereof, and stops secured to said draw-timbers for said followers to abut against, said draw-bar having a squared end, against which said follower F abuts, substantiallyas specified.

7. The combination,with the draft-timbers B, having guide-plates Gsecured thereto furnished with stops g g 9 of draw-bar O, drawstem 0, fitting in a socket in the end of said draw-bar and secured therein by a key, follow-' ers F F F F, tandem-arranged springs D d D d, said draw-stein having a collar C keyed thereto, and a key a, substantially as specified.
