DRAFT-HIGGINS FOR RAlLWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 775,606, dated November 22, 1904.

T0 at whom it may concern.-

Be it known that I, WILLIAM H. MINER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Draft-Rigging for Railway-Cars, of which the following is a specification.

My invention relates to improvements in draft-rigging for railway-cars.

In railway draft-rigging heretofore in use the car-coupler has usually been furnished with a long integral draw bar or shank and with a draw strap or yoke rigidly secured to the rear end of the draw-bar, the strap or yoke embracing or surroundmg the springs and followers and reciprocating between the side plates or stop-castings which are attached to the car-frame. Considerable difficulty has heretofore been experienced, especially where the draft-rigging is of the tandem type, having two or more springs arranged tandem, or one behind the other, owing to the greatlength of the draft-rigging as a whole interfering with the proper and necessary lateral or swinging movement of the coupler when the train passes around curves, and thus causing the couplers to be subjected to lateral or binding strains tending to uncouple the cars or to break the coupler or draft rigging or to wrench or disengage the same from the car.

The object of my invention is to provide a railway draft-rigging of astrong, simple, and durable construction by which the objections or difficulties'experienced may be avoided or overcome and in which the cost or expense of manufacture may be materially reduced, as well as the length of the draft appliance as a whole, and by which the draft-springs and followers may be brought near the front end of the car.

My invention consists in the means I employ to practically accomplish this object or resultthat is to say, it consists, in connection with the car-frame or its center sills or draftsills and the front or cross sill and carry-iron and the spring or springs and followers, of a pair of side plates or stop-castings having the customary stops for the followers to abut against and provided on their inner faces at their front ends with. curved or rounded guides or bearings adapted to engage and guide the longitudinal movement of the coupler drawhead and to limit its lateral or horizontal swinging movement and a draw strap or yoke projecting at its front end between the crosssill and carry-iron and a coupler draw-head having a pivot-lug projecting from its rear face connected by an upright pivot-pin with the front end of the draw strap or yoke, the pivot-pin extending between the front sill and carry-iron and prevented thereby from being disengaged from the parts which it connects. My invention further consists in the novel construction of parts and devices and in the novel combination of parts and devices herein shown or'described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation, partly in longitudinal vertical section, of a draft-rigging embodying my invention. Fig. 2 is a vertical cross-section on line 2 2 of Fig. 1. Fig. 3 is a plan view, partly in horizontal section, with some of the parts removed; and Fig. 4 is a detail cross-section on line A L of Fig. 1.

In the drawings, A A represents the center sills or draft timbers or sills of a car, to which the side plates or stop-castings are secured.

A is the front or cross sill, and A is the carry-iron. a

The side plates or stop-castings B extend to the front end of the car and are furnished with the customary stops or shoulders Z) Z) 6 I) for the followers C C C C to abut against and also on their inner faces at their front ends with rounded or curved guides or bearings 6*, which are adapted to engage the pivot-lug cl, which projects from the rear face d of the coupler draw-head D and which serves to guide the coupler in its longitudinal or forward and backward movement and also to limit the lateral or horizontal swinging movement of the draw-head on its upright pivot D, by which it is pivotally connected to the front end of the draw strap or yoke F. The draw strap or yokeF extends at its front end between the cross-sill A and carry-iron A and the vertical pivot-pin D, connecting it to the s, ASSIGNOR TQ w. n. MINER pivot-lug of the draw-head, is located between the cross-sill and carry-iron and is prevented thereby from all possibility of. accidental disengagement.

The pivot-lug d, projecting from the rear face of the draw-head D, is provided with upper and lower countersinks (Z d which receive corresponding pivot-bossesff on the inner faces of the upper and lower limbs of the draw-head D, at the front end thereof, and which enlarge the bearing or pivotal connection between the draw strap and coupler draw-head and serve to relieve the connecting pivot-pin D from a portion of the buffing and pulling strains to which the coupler is subjected. The pivot-lug 61 of the coupler draw-head is also provided with a rounded or curved rear end D, which bears directly against the front follower C and while permitting the draw-head to turn or swing horizontally on its pivot D also serves to communicate a portion of the buffing strains directly to the front follower and to relieve the pivot-pin D therefrom.

The draw-strap F is furnished with an abutment-blockf at its middle portion, secured thereto by rivets f to bear against the two middle followers. The pivot-pin D is preferably furnished with a head d and nuts cl, which fit in suitable countersinks f in the upper and lower faces of the strap or yoke F, a seat-block G, having flanges g, fitting astride the carry-iron and a slot g extending longitudinally of the draw-bar to receive the end and nut of the pivot-pin is preferably interposed between the carry-iron and the draw strap or yoke.

The coupler is of the ordinary Master Car- Builders type and has the customary knuckle D pivoted to the draw-head D and lock D for holding the knuckle in its closed position.

The side plates or stop-castings B have an upper integral guide or flange b and a lower removable guide or plate 6 for the followers 0 C C C to reciprocate between and to support and guide the same.

I claim 1.
