The upper portion'of each rear edge of the intermediate webs is forwardly inclined, as indicated at 8, so as to permit the ready insertion and entry of the follower between the rear of the cushioning mechanism and the interior face of the loop end of the yoke member. The upper edges of the vertical web 7 are joined by a top web portion or flange. 9, said portion forming a horizontal closure wall for the spaced hollow recesses or chambers 10 formed between said vertical .rearwardly projecting webs 7 in the upper part of the casting. A bottom wall 11 extends rearwardly from the front wall 5, said bottom wall uniting .the lower edges of the vertical webs 7 and forming a closure for the recesses or chambers 12 formed between said vertical webs 7 and .adjacent the bottom of the casting:-

The rear wall 13 Vof the follower is arranged intermediate the top and bottom portions thereof, said rear wall-uniting intermediate portions of the rear edges of the rearwardly projecting vertical webs 7. Rounded .or cur-ved portions 141 are provided at the corners uniting the rear wall with the outermost vertical webs, said curved portions being arranged and adapted to lit within the rounded interior face ofthe yoke loop joining the side arms ofsaid yoke, as shown in Figure 1. The rear wall 13 constitutes a relatively large and effective bearing area contacting .the yoke whereby the drawing stresses are transmitted through the rear of the yoke to the cushioning mechanism and excessive loads transmitted to the Vcar underframing without cutting or otherwise mutilating the yoke. Y

Means is provided for bracing said Lbearing surface, said means including the vertically arranged webs 7, thickened slightly, .as shown at 15, and a plurality of ytransverse horizontally disposed webs 16 uniting the vertical webs 7 and the front and rear walls of the casting. A plurality of chambers or rectangular recesses 17 are formed between the intersecting vertical and horizontal webs,`a series of transversely arranged and substantially alined openings 18 being provided in the thickened wall portions 15 to light-en the casting and provide for the rem val of the cores.

The follower is also provided with means at each side thereof for supporting-.the rear end of the yoke in horizontal alinement and Contact with the bearing surface, said means including projections 19 arrangedupon the outermost vertical webs 7 adjacent the front wall of the follower and adapted to for-m seats for the side arms ofthe yoke. The upper surface of the projections are disposed substantially in a horizontal plane passing through the lower edge .of the rear wall. The projections 19 on the :follower support the yoke, and the follower is in turn slidably mounted upon a plate 2O connected to the draft sills by means of the bolts 21. The plate is shown as extending under the rear follower and under the rear end of the cushioning mechanism, and serves to support both of these elements of the draft rigging to permit their sliding movement when'op erating in service. Openings 22 are preferably `provided in the front wall 5, said openings extending through to the respective up'` per and lower recesses or pockets 10 and l2 hereinbefore referred to.

It will be apparent that by means of the internal flanges and-webs on .a follower con st-ructed in accordance with my present invention, one wall .is so formed as to provide a full and complete bearing surface with which a movable element of the draft' rigging may .cooperate without mutilation and that all stresses to which the associated parts may be subjected in service are amply resisted by sufiicientsections so economically arranged that the casting while pos-y sessing great strength is comparatively light in weight and is, moreover, a-vsimple .cast- .ing both to mold and cast.

The distance between the front and rear faces of the follower, thatis, the depth or .lil-ler distance between the outer surface' of the front wall 5 andthe outer surface of the rear wall 13 is made to correspond with the difference vbetween :the standard distance lof twenty-four and iive-eighths inches, required vbetween the rear end ofthe coupler butt and the front face of the draft yoke loop and the length of the cushioning mechanism be used. Before this distance was standardized, the difference between it and the length yof the cushioning mechanism could be made so small that a simple solid follower plate', suoli vas shown at 1.9 in the Patent No. 1,097,738 to Symington, could be used or, if desired, the fol-lower yplate or plates could be dispensed with. lilith the Standardization yof this distance, the problem of filling the relatively large space, when a short cushioning mechanism is used, without unduly adding .to the weight of the draft rigging, presented itself. This has been satisfactorily lsolved by ,thje present device. y
