DRAFT-RIGGING FOR RAILWAY-CARS.

Application filed December 26, 1911.

i lllinois, have invented a certain new and useful Improvement in Draft-Rigging for Railway-Cars, of which the following s a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specifica-- My invention relates to improvement in draft ri ging for railway cars.

One oiject ofmy invention is to provlde a draft rigging employing a draft yoke n which the side members of the yoke extend in a horizontal plane and commonly known as a horizontal yoke, and-a draft rigglng in which the cushioning mechanism or compression resisting device may. always be maintained in longitudinal alinement both in a horizontal and a vertical plane between the draft members of the railroad car, and thus insure an even distribution of shocks. to all the parts of the cushioning mechanism, and an even transmission of shocks therefrom to the draft members.

A further object is to furnish a draft rigging employing a horizontal draft yoke n which effective provision is made for limiting the movement of the followers and the travel of the draw bar, and one having a 11miting stop casting suitably constructed to permit the easy insertion. removal and replacement of the cushioning mechanism of the draft rigging.

A further object is to provide a railway draft rigging which may be readlly at tached to the draft members and in which the shocks transmitted thereto may be evenly distributed alongthe draft members -of the car.

I have shown one form of means to prac ,tica-lly accomplish these objects, the means in part comprising a cradle in the'form of two substantially rectangular blocks of novel construction within and upon which the longitudinally movable cushioning member of the draft rigging is supported; the blocks composing the cradle further serving as lower limiting strip members for the followers to abut against.

The inventioif'consists in the novel construction of parts and devices, and in the novel combination of parts and devices here- Specification of Letters Patent.

I .in shown and described, and more particularly pointed out in'the claims.

In the drawings forming a part of this specification Figure 1' is an inverted plan view partly in-longitudinal horizontal section of a draft rigging embodying my inven-tion, and showing the parts in normal position. Fig. 2 is a view similar to that inv Fig. 1 showing the parts in full buff. Fig. 3 is a vertical cross section on line 3, 3 of Fig. 1. Fig. 4 is a perspective view of one of the blocks or limiting stop members which forms one of the two members of the cradle, and showing the inner face thereof. Fig. 5 is a view similar to that in Fig. 4 and showing the outer face of the block or the face thereof engaging the draft member and Fig. 6 is a detailed side elevation of one of the side castings with a block of the cradle applied thereto.

In the drawings 10-1O are the draft members or center sills. of a railway car, 11 the buffer block, v12 the draw bar carry iron, 13 the draw bar, 14 a horizontal slot through the draw bar t receive the coupler key 15, the slot 14 being elongated longitudinally of the draw bar. 16 is the horizontally disposed draft yoke comprisingthe side memsecured thereto as by means of a rivet 20.

and an open front end for the insertion of the draw bar 13, the sides of the yoke adjacent the open front end being provided with horizontal slots 21 to receive the key 15.

Within the draft yoke 16 is the front follower 22, which normally abuts against the rear end of the draw bar 13, the rear follower 23..and between the followers, the 1011- gitudinally movable cushioning member or compression resisting device 24, preferably a friction cylinder with contained friction mechanism. The friction mechanism within the cushioning member may be of any suitable type. Side plates or stop cas ings 2525 are suitably secured to the draft members 10 as by means of rivets 26-26. Slots 27 are provided in the side cast-ings and draft members and are longitudinally extended to permit the movement of the ends of the key 15 therein upon movement of the draw bar. Longitudinally ex tending follower guides 2898 are suitably secured at their ends to the lower portion of the side plates 25 by bolts or other suitable means, and preferably rest, intermediate their ends, upon the tie plate 29, which is removably secured to the draft members 10, as by the bolts 3030. The follower guides serve also to support the followers in position within the yoke.

' Each of the side plates or stop castings is furnished with preferably integral main upper and lower front stops or shoulders 31 and .32 respectively, and main upper and lower rear stops or shoulders 33 and 34 respectively for the followers to abut against. The side plates are each also provided with a longitudinal median groove 35 .which the sides 17 of the draft yoke 16 travel in reciprocating movement. Each side plate also has preferably formed integrally therewith upper front and rear intermediupper inner edge 41 shaped to conform with the adjacent surface of the cushioning member 24, and is furthermore provided preferably with a plurality of quadrilateral tapered bosses 42, preferably three in number, arranged upon its outer vertical side 43. The bosses 42 of each block are received within corresponding quadrilateral tapered sockets 44 provided in the adjacent wall. of each sideplate 25. Each block is provided with openings 45 to permit the passage and the insertion through alined perforations 46 in the bosses, 47 in the side plates, and 48 inv the draft members, of the bolts 49, each provided with 'a suitable head 50, and

threaded at its outer end to receive the nuts I 51 by means of which the blocks 4040 are tightly drawn into position. The bolts 49 serve to hold the blocks 4040, to the side plates, and also assist in securing the side plates to the draft members.

In preferable construction the central socket 44 in each stop plate receives the head of. a rivet passing through the side plate and draft member. The blocks 40-40 are attached, one to each side plate, and form at the ends, lower, front and rear intermediate limiting stops or shoulders 52 and 53 respectively. The intermediate stops or shoulders 36- 37-52-63 effectively limit the movement of the followers and the travel of the draw bar, and prevent the within tain it in its proper position horizontally and vertically and hence in its position of greatest shock absorbing efficiency.

In the drawings, I have shown one form of a draft rigging embodying my improvements, but I wish it to be clearly understood that the same is merely illustrative, and that all changes and modifications are contemplated as fairly fall within thescope of the appended claims. Claims 1. In a draft rigging for railway cars, the

combination with the thaw bar, draft yoke, followers and compression resisting device, of side plates each provided with upper and lower main and intermediate:stops,

the lower intermediate stops comprising a substantnilly rectangular block, each of said blocks being removable.

2. In a draft riggingfor railway cars the combination with the draw bar, hori. draft yoke, followers, side plates and c ioning member, of a cradle supper-til cushioning member, the side plates being provided with upper and lower front '5 rear main stops'for the followers to abut against and havingupper intermediate steps, the cradle forming lower intermediate stops to' limit the travel of the draw bar. said side plates being also each provided with longitudinal median grooves to receive the draft yoke.

3. In a draft rigging for railway cars, side plates provided with removable limiting stops, and means for securing said stops to the side plates, each stop connarising a hollow member outwardly provided with perforated bosses, said hollow member having openings to receive said means within the hollow portion thereof, and the side plates being provided with sockets adapted to receive saidbosses therein.

4. In a draft rigging for railway cars, the combination of side plates provided with quadrilateral tapered sockets with removable stopsfor' said side plates, said stops having quadrilateral tapering bosses adapted to be received within said sockets.
