2 SHEETS-SHEET l- Q N @WN S JOHN F. OCONNOR, OF CHICAGO, ILLINOIS, ASSIGNOR T0 WILLIAM H. MINER, 0F OHAZY, NEW YORK.

To all whom it may concern:

Be it known that 1, JOHN F. OCoNNoR, a citizen of the United States, residing at 0hr cago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Railway-Car Draft- Riggings, of which the following is a full, clear, concise, and exact description, reference being had. to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in railway car draft riggings.

Objects of the invention are to provide a draft'rigging for railway, cars which comprises few parts, compactly arranged and readily assembled and disassembled.

Other objects of the invention are the provision of: A rigging for railway cars wherein a oke is detachably connected to the draw-bar; a yoke comprising two members and together having a' friction shellformed integrally therewith; integral means on the two pieces of the yoke and elements of the friction mechanism which cooperate to prevent lateral separation of the yoke members;

- and a single fixed key by which all the bud and draft shocks are transmitted to the sills, said key preventin rearward movement of the yoke under bu and preventing forward movement of certain elements of the friction mechanism under draft.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices, as herein shown, described and claimed. i

In the drawing forming a part of 12,213 specifica ion, Figure 1 is a central, longit inal vert cal section view of a draft rigging embodying my improvements, the coupler being shown in side elevation. Fig. 'is a horizontal combined sectional and plan view, the r on t e line 22 of Fig. 1. Fig. 3 is a transverse vertical sectional viewi taken on the line 3-3 of Fig. 1.1 Fig. 4 is a view similar to Fig. 3 illustrating another embodiment Speoiflcation of Letters Patent.

plarts in section being taken substantially Patented Mar. 12, 1918.

Application filed March 3, 1915. Serial No. 11,717

inforcing plates 1111, said plates and sills being slotted to 'removably receive therethrough a relatively fixed transverse key 12', the key being held in place by any suitable means such as cotters 13. The draw-bar 14: is shown as of the M. C. B. type and provided with upper and lower shoulders 15 with which cooperate under draft, inturned shoulders 16 formed at the front ends of two loop-like members 1717 which together form a'yoke designated generally by the ref- 'erence A. Each of said yoke members 17-17 is preferably of like construction and comprises an upper arm 18, lower arm 19 and side wall 20 which extends from the front to a point somewhat to the rear of the longitudinal center thereof. The upper and lower arms 1819 of each yoke member are provided on their inner faces, as clearly indicated in Figs. 1 and 3, with friction suffaces 21-21, each of said surfaces as shown in the structure illustrated in. Fi s. 1 to 3, being longitudinally grooved as i dicated at- 22. Reinforcing ribs 23 are provided on the outer surfaces of the yoke members surrounding the friction shell formed integ-' 27. The sides 20 of th'e'yoke members are also provided with elongated slots 28 through which the key 12 extends, said slots being so arranged that the yoke is permitted'forward movement relatively to. the key but is prevented from rearward movement. Said slots 28 are surrounded by laterally extendin'g flanges 29 arranged to strengthen the 1yoke and also to assist in centering the yoke etween the center sills.

As clearly shown. in Fig. 1, the follower wedge block 27 has an elongated centrally located slot 30 through which the key 12 extends, said slot 30 being open at its front end and s0 arranged, as to permit the in ward. movement of the wedge but preventing its outward movement. The friction shoe-26 and wedge'block 27 areprovided with inclined faces inthe usual manner and having anti-friction rollers 31 therebetween.

,As most clearly shown in ,Fig. 3, each of the friction shoes26 is provided with a pair of integral longitudinally extending ribs 32 arranged to'slide and engage in the longie Milo ,lly eiitehding grooves 22 fort-iced on llllkfilf' feces of the friction shell portions interi I eduelly compres ed U11- is prevented from thus causing the $38.1 con portion oi the yoke to serve: as e v p for the spring 24:. The draw-bets .23 free to move inwardly relatively to the yolgze under but", thereby forcing the Wedge block 2? inwardly and exerting pressure from the Wedge through the shoes to the friction. shell, which is resisted by the s; m; 4!; ii; the usual manner.

Although I have herein shown and described what 1: now consider the best means of carrying out my invention, yet it will be understood by those skilled in the art that nun'ierous changes and modifications may be made in the details of. construction and em rengement of parts, Without departing from the spirit of the invention, and all such changes and modifications are contemplated come Within the scope of the cl eiins appended hereto,
