DRAFT-RIGGN G F OR RAILROAD-CARS.

Application filed July 13, 1916.

To all "1r/7mm 'it may concern it known that l, donn F. OCoNNon, a citizen of the United States, residing at Chicago. in the county of Cook and State of lllii ois, have invented certain new and useful lmprovement in lDraft-Rigging for Railroad-Cars, 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.

My invention relates to improvements in draft rigging for railroad cars, and more particularly to the means for connecting a draw-bar to a draft yoke.

The object of my invention to provide a readily detachable connection between a draw-bar and a draft yoke.

lu the drawings forming a part of this 'f specification, Figure 1 is a side elevation of a draw-bar (only the rear end thereof being shown) and a draft yoke embodying my invention. Fig. 2 is a horizontal section taken on line 2 2 of Fig. 1. Fig. 3 is a transverse section taken on line 3-3 of Fig. 1. Fig. et is a transverse section taken on line 4 Yl of 1. Fig. 5 is a perspective view of one of the draw-bar shoulder blocks.

Referring to the drawings, the numeral 6 indicates draw-bar, (only the shank and butt thereof being shown) the butt being referenced 7 and having the usual top and bottom draw-bar shoulders 8, 8, The yoke comprises an upper limb 9, a lower limb 10, a rear connecting member 11, and has at its forward end a hollow head 12, preferably integral therewith, to receive the rear end of the draw-bar. rllhe yoke is adapted to employ locking mechanism to secure the same to the draw-bar, which engages the draw-bar at its sides and which may be conveniently removed from underneath; and my invention is adapted to be employed either with draw-bars specially made with shoulders at either side, or it may be used with the usual d 1aw-bar with top and bottomA shoulders, by reason of the special structure which l will now describe.

l provide on either side of the draw-bar the draw- bar shoulder blocks 13, 13. These blocks are counterparts of each other, and therefore l will describe only one. lt consists of a side plate 14 having upper and lower inwardly extended members 15, 15 which together with the side plate 14 form Specification of Letters Patent.

Serial No. 109,005.

a recess 1G within which the butt of the draw-bar is received. rlhe members 15, 15 are provided near their forward ends with the shoulders 17, 17 that engage the shoulders 8, 8 of the draw-bar, and the plate 1l is provided with a lug or' short key 18 which is adapted to enter the usual transverse slot 19 with which the draw-bar is provided. rl`he outer face of the draw-bar shoulder block is provided with a vertical shoulder 20. YWhen the shoulder blocks are placed in position upon the coupler, they are fastened together by a rivet 21 or similar suitable means passing through the perforations 22, 22 in the blocks. `When thus arranged, the draw-bar is provided through the medium of the said blocks with vertical shoulders 2O at its sides, and the inner faces of the side plates 2li, 24- of the yoke head are provided with the vertical grooves 25, 25 which receive from underneath each a key 26, the said keys each engaging the adjacent shoulder 20 provided upon the draw-bar. The yoke head is provided with a pair of dependent lugs 27, 27 transversely perforated for the passage of the pin 28 which extends through the perforation 29 found in the lower ends of each of the keys in order to hold the same against accidental displacement from their position in the yoke head.

ln assembling the draw-bar and yoke, the draw-bar is inserted through the forward opening' of the yoke, the keys are slipped into their position from underneath and locked therein by means of vthe pin 28, which is held against accidental loss by suitable means such as the cotter and to remove the draw-bar, the reverse operation is employed.

l claim:

1. ln a draft rigging, the combination with a draw-bar having shouldered sides, of u draft yoke having a hollow head to receive the draw-bar, and keys, the sides of the vhead being provided with vertical grooves, the keys entering said grooves and engaging the shoulders of the draw-bar, said keys being removable downwardly when the yoke and draw bar are in position on a car.

2. ln a draft rigging, in combination: a draw-bar. a yoke having sides adjacent the sides of the draw-bar, vertical keys inter posed between the said sides of the yoke and the draw-bar to secure the drawebar within the yoke, said keys being removable downwai-diy when the yoke and draw bar are in position on a car.
