In said drawings, 1O denote the usual center or draft sills of a railway car, preferably of channel section; 11, an angle end sill of the car; 12, end wall sheathing; 13, a floor plate or cover plate for the sills; and 1 1, a buffer block secured to the angle 11 and end sill member 15, the latter being secured to the center sills 10 by the tie plate 115.

In carrying out my invention, the draft sills 10 are provided with suitable slots to accommodate portions of two reinforcing or check plates 1616 secured to the outer sides of the sills. Each of said plates 16 is provided at the front end thereof with an elongated key-receiving opening 17 intermediate its ends with another elongated key-rcceiving opening 18; and at the rear with a third key receiving opening 19. The plates 16 are provided with flanges 117, 118, and 119, sur rounding each of the openings 17 18 and 19 respectively, portions of said flanges being extended through the corresponding slots in the draft sills as best indicated in Figure 2, it being apparent that said flanges provide larger bearing and wearing areas for the respective keys which are received therein.

In the draft rigging as shown, is included a standard coupler indicated broadly by the reference character A; a pair of links or side arms BB; a front follower C; a rear fol lower D; a friction shock absorbing mechanism indicated conventionally at E; a conpler key 20; a front follower key 21; arear follower key 22; and a fourth key 23, function of the latter being hereinafter described.

The front and rear followers 0 and D are supported by the keys 21 and 22, respective ly, which are passed through suitable slots in said followers and corresponding slots 121 and 122 in the links. To sustain the shock absorbing mechanism. E, a detachable saddle plate 24 may be employed, the same being detachably bolted to the draft sills and the front follower C may have bosses 25 projecting into the end wall of the friction shell casing to help support the latter.

The rear follower-supporting key 22 is normally disposed at the rear end of the slots 19. The front follower key 21 normally disposed at the forward ends of the slots 18; and the coupler connecting key 20, which extends through the coupler shank, is normally disposed intermediate the ends of the slots 1? and somewhat nearer the front ends thereof than the rear ends. The slots 121 in the links are so arranged as to permit the links to move forwardly a short distance relative to the key 21, and the slots 122 permit the links to move rearwardly with respect to the key 22, so that, in buff, load is not transmitted through the links to the key 21 and the links are free to move rearwardly independent of the key 22. In draft, the links are free to move forwardly a limited distance relative to the key 21, but move the rear key 22 forwardly in unison therewith. The slots in the links for the key 20 will be so disposed as to move the key 20 and links in unison when the coupler A is pulled outwardly under draft.

As will be evident from the drawings, the links B are confined practically to a straight line movement, but lateral play or angling of the coupler A is permitted with reference thereto, due to the slotted key connection between the coupler shank and links and the fact that the links are spaced apart a greater distance than the maximum width of the coupler shank, it being evident that the slot in the coupler shank is somewhat wider than the key 20, so as to permit lateral motion of the coupler with respect thereto. It will also be noted that the keys and slots are so arranged that the movement under bull is con-' siderably greater than that permitted under draft, the illustration indicating an arrangement wherein the buff movement may be approximately five inches and the draft about two or two and one-half inches.

In carrying out my invention, the links 13 are straight for the greater part of their length, that is, from points in line with the coupler key 20 to the rear end. Forwardly of the coupler key 20, each link 13 is provided with an extension 26, inclined downwardly and provided at the front end thereof with a key-receiving opening 27. The supporting key 23 is detachably received within the openings 27, the vertical height of the latter bein greater than the thickness of the key and or the turned ends thereof, so as to permit insertion or removal of the key 23 as indicated in Figure 3. Tl e extended portions 26 are of such length and the location of the key 23 is such that the key provides a support for the coupler shank at a point closely adjacent the coupler head, as clearly illustrated in Figure 1, and when the weight of the shank is on the key 23, the latter will be prevented from coml ing out laterally on account of the turned ends 123 thereof, shown in Figure 3.

In the arrangement which I have shown, it will be observed that no carry iron of usual character is employed or necessary, and preferably the draft sills will. be suitably cut away as indicated at 110, to accommodate movements of the key 23. l/Vith the parts in the normal or full release position as shown in the drawings, it will be observed that in all positions of the parts the coupler is sup ported closely adjacent the head thereof by the key 23 at a point forwardly of the coupler key 20, whereby the weight of the coupler head is overbalanced by the combined weight of the links rearwardly of the key 20 and the followers, and to some extent also by the shock absorbing device proper. I-lence, as the links are supported at three spaced points by the keys 20, 21 and '22, and the forwardly extended portions sustaining rig d wlth thelinks,

all tendency'of the coupler to drop or sag or fulcrum about the coupler key 20,is prevented and the coupler'head of the coupler'sh'ank is maintained in its proper horizontal position in axial alignment withthe followers and shock absorbing means. the coupler key 20- is relieved of the usual twisting or torsional, strain thereon sincethe coupler is supported the key 23. o

With my arrangement as shown and'described, it is evident that a-constant axial alignment of the coupler shank and shock absorbing device is at all times maintained in all operative positions, of "the parts whereby the construction is particularly adapted for draft riggings having long travel. It is manifest that the improvements which I have shown do not appreciably add'to the cost'of manufacture, v i

I have herein shown andfde scribed' what I now consider the preferred manner of carrying out my invention, but the same is by way of illustration only and not byway of limitation.
