DRAFT-RHGGING FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 692,()74, dated January 28, 1902 Application filed July 22, 1901. Serial No. 69.243. (No model.)

TO ctZZ ww it it may conccrn;

Be it known that I, DELMAR C. Ross, a citizen ot' the United States, residing at Detroit, in the county of Wayne and State of Michigran, have invented certain new and useful Improvements in Draft-Rigging for Ralway- Cars, of which the following is a speeification, reference being had therei n to the accompanying drawings.

The invention relates particularly to a draftrigging or draw-gear adapted when applied to a car to relieve the body of the latter from the strains and shocks incident to coupling and buffing; and the invention consists in the novel construetion of the draft-rigging and in the peculiar arrangement and combination of its various parts, whereby a more durable draw-gear is obtained and one that may be more cheaply manufactured than those now in use. i

In the drawings illustrating my invention, Figure 1 is a horizontal section through the draft-rigging, some of the parts above the plane of section being shown; and Fig. 2 is a perspective view of the parts of the rigging.

The reference-letters A and B designate the usual longitudinal sills or draft-timbers of the car, to the inner faces of which are Secured bers are preferably malleable-iron platesof like Construction, each being provided at its opposite ends with shoulders &and b, forming therebetween a poeket or chambcr c. The draft members are also provided each with a carrier-bar D, which is adapted to be detachably secured to the draft-bar by suitable bolts extending through openings (l and e in the draft memberand carrier-bar, respectively.

E and F designate spring-supporting followers which have a slidingengagement with the draft members, the followers intel-looking one with another and being mounted upon and supported by the carrier-bars. As shown, each follower comprises a body member or section f, having oppositely-arranged spring retaining arms g and h projecting from one of its sides, and an end section t' independent of the arms and body member and adapted to abut against the tree ends of the arms, as indicated in Fig. l. The inner 'faces of each pair of spring-retaining arms are curved or grooved out in the manner indicated in Fig. 2, the arms being substantially L or angle shaped in cross-section for the purpose of embracing the coiled draft-springs G, which the followers carry. The followers interlock, as indicated in Fig. 1, with the inner faces of the body members in proximity one to the other, so that the two draft-springs upon the draft or thrust of the draw-bar will be simultaneously' compressed. When the followers are arranged in position within the housing formed for the same by the draft members, the parts are so proportioned and the shoulders a and b so arranged that the body members of the followers are prevented from abutting under all circumstances. Thus I have provided means whereby the liability ot' breakage of parts due to the striking of portions of the followers against each other as the springs are released is prevented. I have also provided means for limiting the inward movement of the followers, and thus limiting the compression of the springs, the means consisting of stops I-I, one at the upper edge and in proximity to one end of each of the draft members, and similar stops I, arranged at the opposite end in proximity to the lower edges, as plainly indieated in the drawings' In this manner it will be observed that when the springs are compressed under the draftor thrust of the draw-head the opposite ends of each follow'er abut against the shoulders described, and thus the strain incident to coupling and bufiing is distributed equally and evenly to the draft members and to the car-body, the liability of breakage' being thus reduced to a minimum. i The draw-bar (not shown) maybe of any suitable eonstruction, the shank J of which abuts against one of the detachable end sections I of the followers and is 'connected to the followers by means of a yoke or strap K, Fig. 1, which eneircles the followers and is attached at each end to the shank in the usual manner.

From the Construction of the draft-rigging as of the same are all interchangeable, being IOO lowers travel.

of like Construction. Furthernore, When it is desired to remove the foiiowers for the purpose of repair or replaeement they may be disengaged from the draft-bars by simply removing the carrier-bars upon which the foi- To allow of the insertion or withdrawai of the foliowers in the manner set forth, the stops I of the draft-rigging are earried by the carrier-bars, so that they may be detached with the latter. Also for convenience I preferably form recesses, such as I', in the draft members for the reeeption of the stops I, as plainly shown in Fig. 2.

What I claim as my nvention is- 1. The combination with the draft members Secured to the ear-sills, of interiocking followers having a sliding engagement with the draft members, said followers beingheld from abutting one against the other, and springs carried by the followers.

2. The combination 'with the draft members adapted to be secured to the car-sills, of a plurality of aXiaHy-arranged spring-supporting; -followers having a sliding engagement With the draft members, said followers inter-looking and being held from abutting one against another upon their ontward movement, and springs arranged within the followers.

3. The combination with the draft members adapted to be seenred to the ear-sills, of two interlocking and axially-arranged springsupporting followers having a sliding engagement With the draft members, sprinzs within the followers, and fixed stops upon said draft members against which the inner and outer ends of each follower are adapted to strike upon the compression of its springsl 4 The combination with the draft members adapted to be Secured to the car-sills, of carrier-bars detachably Secured to the draft members, a piuraiity of interioeking and spring-supporting followers mounted and adapted to travel upon the carrier-bars, springs carried by the followers and stops rigidly Secured' to the carrier-bars and detachable with the latter, said steps limiting the inward movement of the foHoWers.

5. The combination with the draft members adapted to be Secured to the ear-sil ls, of
