MEANS OF CONNECTING DRAW-BAB- TO DRAFT-YOKE IN RAILWAY DRAFT -RIGGING.

Specification of Letters Patent.

Patented Sept. 18, 191?.

. Application filed September 13, 1912. Serial No. 720,153.

To all whom it may concern:

Be it known that I, STACY Bl HASELTINE, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Means of Connecting Draw-Bar to Draft-Yoke in Railway Draft-Rigging, 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 means of connecting the drawbar to the draft yoke in railway draft rigging.

The object of my invention is to provide a simple and eflicient means of connecting the drawbar and draft yoke in railway draft rigging, and one in which the drawbar and draft yoke may be easily connected and disconnected.

In the accompanying drawings forming a part of this specification, Figure 1 is a side elevation of the forward end of a draft yoke and the rear end of the drawbar embodying my invention. Fig. 2 is a plan view, partly in horizontal section on

line

2, 2 of Fig. 1. Fig. 3 is a longitudinal, vertical section on line 3, 3 of Fig. 2. Fig. 4 is a cross-section on

line

4, 4 of Fig. 1. Fig. 5 is a perspective view of a block. Figs. 6 to 10 inclusive illustrate a modification; Fig. 6 being a side elevation, Fig. 7 a par'ial section on line 77 of Fig. 6, Fig. 8 a longitudinal vertical section on line 8-8 of Fig. 7, Fig. 9, a cross-section on line 9-9 of Fig. 6, and Fig. 10 a perspective view of ablock.

Referring to the drawings, 11 reperesents the shank of a draw bar of usual construction, 12 the butt of the draw bar, 13 a draft oke, the forward portion of which is shown 1n drawing, 14 the upper strap and '15 the lower strap thereof. The draw bar is pro vided with the upper and lower

transverse shoulders

16 and 17 respectively. The upper strap 14 of the yoke is forwardly provided with a downwardly turned gib 18, engaging the upper shoulder 16 of the draw bar. Substantially at a point in line with the rear face 19 of the butt of the draw bar, the lower strap 15 of yoke 13 has a downward turn 20, in front of which the lower strap is forwardly extended in a plane substantially parallel with the opposite portion of the upper strap and a suflicient distance therefrom to permit the butt of the draw bar to clear the gib 18, in inserting it through the forward opening of the yoke. The upper and lower straps of the yoke are forwardly joined by the lateral webs or

plates

21, 21, thus giving the yoke a head with the box-like opening 22 formed between the webs and the yoke straps.v The webs or

plates

21, 21 are each provided near their lower portions with the L-shaped slot 23 to receive the transverse L-shaped block 24. The block 24 has an upright member 25 and a flat member 26, having the shoulder 27 against which the lower shoulder 17 of the butt 12 of the draw-bar engages in normal position with the draft rigging. The block 24 extends at its ends beyond the outer edges of the

plates

21, 21 and is provided with the

perforations

28, 28 to receive the

keys

29, 29 which hold it against accidental displacement. The top face 30 of the member 26 75 of the block 24, when within the

slots

23, 23 is substantially even with the portion of the inner or upper face 31 of the lower yoke strap 13 back of the bend 20 therein. In the modification illustrated in Figs. 6 to 10 inclusive the draw-bar shank 32 and the butt thereof 33 are provided with the usual upper and lower

transverse shoulders

34 and 35 respectively; the draft yoke 36, the forward end of which is shown in the drawing, has an upper strap 37 and a lower strap 38; the upper strap 37 being provided with a downwardly turned gib 53 engaging the upper shoulder 34 of the draw-bar. The lower strap 38 is provided with the downward turn or bend 39, in front of which it is forwardly extended in a plane parallel with the opposite portion of the upper strap and a sufiicient distance therefrom to permit the butt of the draw-bar to clear the gib 38 in inserting the draw-bar through the forward opening of the yoke. The upper and lower straps of the yoke are forwardly joined by the lateral webs or

plates

40, 40, thus roviding a head for the yoke with the box-like opening 100 41 into which the draw-bar is received. The

webs

40, 40 are transversely provided near their lower edges with the slot 42 to receive the transverse key 43, which passes therethrough and through the transverse perfora- 105 tion 44 in the L-shaped block 45. The block 45 has an upright member 46 and a flat member 47, forming the shoulder 48, against which the lower shoulder 35 of the butt of the draw-bar engages in normal position 110 I with'the draft rigging. lhe top face 49 of portion orupper face 50 of the lower yoke strap 38, back of the bend 39 therein. The

key 43 is provided with the perforations 51 51 at its ends to receive the cotters or pins 52 52.

The operation of my device will be clear. To remove the drawbar, the block is withdrawn, permitting the butt of the draw-bar to be moved downwardly so that the upper shoulder thereof may clear the gib of the upper yoke strap and be forwardly withdrawn. To connect the draw-bar with the Y yoke, the butt of the draw-bar is inserted in the box-like opening of the member of the yoke, lifted to position so that the upper shoulder of the draw-bar engages the g'ib in the upper strap of the yoke and then the block is secured in the lower portion of the said'opening so that the shoulder thereon engages the lower shoulder of the draw-bar and the block is then secured in position in the preferred form by inserting the pins in the ends thereof and in the modified form by passing the key therethrough. It will be seen that on the rearward movement of the draw-bar, the butt of the same will engage directly with the followers or compression resisting members within the yoke and without strain upon the yoke, that is, the draw bar is free to move rearwardly independently of the yoke, while on the forward movement of the draw-bar the shoulders of the same will be in engagement with the shoulders provided. on the upper strap of the yoke and upon the block, v

I claim:
