DRAW-BAR ATTACHMENT FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent NO. 427,990, dated May 13, 1890.

Application filed March 10, 1890. Serial No. 343,381. (No model.)

To 60% whom it may concern.-

tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a draft-rigging or draw-bar attachment for railway-cars, and it has for its object to provide simple, durable, and comparativelyinexpensive means for this purpose, by which the draw-bar will not be unduly restricted in its movement back and forth and yet be held firmly in position, said means being of greater strength and better adapted to remain firmly in the position where secured, no matter how great the strain exerted thereon through the draw-bar, than-the means now commonly employed to secure draw-bars to cars; and it consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical longitudinal section through my improved attachment, showing the draw-bar partly broken away; Fig. 2,a plan View of the coupler and attachment; Fig. 3, a detail plan view of attachment with draw-bar and spindle removed; Fig. 4, a perspective view of the inner face of one of the draw-bar lugs or castings; Fig. 5, a perspective view of the outer face of one of the draw-bar lugs or castings; Fig. 6, a perspective view of the spindle and key locking device; Fig. 7, a perspective detail view of the looking or retaining key; Fig. 8, a perspective view of the thimble, and Fig. 9 a detail view of the end of the spindle.

Similarletters refer to similar parts throughout the several views.

A represents the end sill of a railway-car, B the draft-timbers for the support of the draft-rigging or draw-bar attachment, and O the bu i'fer head'block. The draft-timbers are rigidlysecured to the longitudinal sills D of the car by means of bolts, and are arranged at a suitable distance apart to permit the insertion of the draw-bar. of the coupler between them.

and prevent it from being pushed or thrown out of line in coupling cars. A thimble 19 (see Figs. 1 and 2) surrounds each of the bolts a, in order to prevent the breaking of said bolts if the draw-bar should happen to be forced violently against the same.

The draft-timbers are recessed on theircontiguous faces, as at c, in order to receive the ribs cl, formed 011 the rear or outer faces of the lugs or castings F, which are secured to said timbers by means of screw bolts and nuts 6, said bolts passing through perforations f formed in said lugs or castings. As clearly shown in Figs. 4 and 5, three of the perforations f for bolts e are arranged at'each end of the lugs or castings, and one at the center to insure the rigid and secure attachment of the lugs or castings to the draft-timbers and, in

connection with the ribs, preventing the lonside of the lugs or castings, and the thickened and enlarged ends '6 at the lower side of the lugs or castings, the end or cross pieces j, and the ribs d on the outer or rear face of the lugs or castings, all of which are cast together or in one piece.

The side pieces or flanges h and the crosspieces j project from the back portion g of the lugs or casting and form a rectangular inclosed space or recess for the ends of the follower-plates G, the edges of said plates resting on and between said side pieces or flanges and sliding thereon as they follow the movement of the draw-barback and forth, and the end or cross pieces j form shoulders or stops at both ends against which the follower-plates press alternately as the draw-bar is moved in or out by the movement of the cars. Thus it will be seen that I provide ample workingspace for the follower-plates, and a firm support for the same, as well as means for holding them in position and guiding them in their movemen t, and shouldersor stops against which they press and which prevent them being drawn or pushed out of place, and that the whole is lirmlyheld in position in the draft-timbers and consists of but two pieces or parts. One of the bolts at each end of the castings or lugs F passes clear across to the opposite casting and passes through the same, and surrounding these bolts are thinr bles ll, which rest at each end against the enlarged endsj of the flanges 71, the object of which is to prevent the castings and drafttimbers being drawn too closely together in bolting the same in place, and thus narrowing or eontractin g the working-space between the castings and pinching or tightening the follo\\'er-plates, so that their free movement is either rendered difficult or uncertain, or they are tightly held in place against movement in either direction.

The follower-plates are inserted between the castings after the latter are bolted in place by simply passing them up between the castings from the under side thereof until they are between the flanges 71, and then turning them crosswise and into place, as shown in Fig. 3, in which figure one of the plates is shown in position with its ends between the flanges and the other as having one end inserted between the flanges at one side and the other end in such position that by simply pushing it in the direction of the arrow it will be forced between the flanges into position, as indicated by dotted lines, for operation.

Between the castings F the springs K, one within the other, as is usual, are located and are prevented dropping out in case of thebreaking of the spindle l. by the lower or bottom flange 71, which, as shown, is of slightly greater width than the upper flange h. The springs K surround the spindle, and their ends rest against the follower-plates G, through the centers of which the spindle passes. The spindle is formed with an enlarged head 0, which may be of any desired shape or configuration of greater diameter than the openings in the follower-plates, thus preventing the spindle working through the openings, and also when in use forming a stop, so as to catch against the interior flange or shoulder 1,), formed at the inneror rear end of thedrawbar M, to hold said draw-bar in place, as shown in Fig. '1. The spindle is inserted through the front or forward end of the draw-bar and through the plates and springs. At one end two slots m andm are formed in the spindle at a short distanceapart and in linewithcach other, the outer of which slots in being of greater length than the inner slot in, and lo cated a short distance from the extreme end of the spindle, as best shown in Fig. 9, a thimble N, having a flange 71 at one end and a slot (1 through its body portion, and having its other end formed with a double incline or bevel r, and diainetrically-opposite reccsess .5, said incline or bevel commencing at the opposite sides of the recesses and running outward toward the end of the thi mble, as clearly shown in Fig. 8. A key 1, having a shoulder 15 at one end, and a perforation 11, adapted to receive a split ring 1*, is provided to lock the thimble in place on the spindle, and a retaining-key R, having a projection 11 on one side edge and adapted to enter slot m, is provided to force the thimble against the f ollower-pl ate. After the spindle is in place the thimble is slipped thereon and turned until its recesses s coincide with the slot m. The key R is then passed down through. the slot and recesses until the ends of its projection '11, which is of the same or slightly less diameter than the end of the spindle,completely enters the slot in said spindle, when the thimble is given a quarter-turn, locking the key R in the slot and bringing the slot in said thimble in line with the slot in of the spindle, and, owing to the inclined or beveled end of the thimble, forcing the same up against the follower-plate and compressing the spring so that the key 1 may be readily inserted in the slot m. By this arrangement all slack that may exist between the ends of the springs and the plates is taken up and the thimble is held rigidlyagainstthe plate.

llavingthus described my invention,whatl claim as new, and desire to secure by Letters Patent, is

l. The combination, in a draw-bar attaehment for railway-cars, with the draft-timbers having recesses on their contiguous faces, of the castings having ribs formed 011 their rear faces adapted to fit said recesses, and the iongit-udinal flanges and the cross-pieces formed on their front faces, the whole being cast in one piece, substantially as described.
