0 all whom it may concern .MITGHELL,

a citizen of the United. States, residing at Chicago, inthe county of Cook and State of Illinois, haveinvented a certain new and useful Improvement 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 an improvement in draft rigging'for-railway cars.

' One of the objects'of my invention isto promotethe safetyof railway employees by providing a railway draft rigging in which an increased space between the railroad cars to which'it is applied may be obtained.

Myjinvention is of such a nature that it permits the use of the present equipment and so rearranges the-present equipment that this additional spaceijsxprovided. In one form of application of'my in-vention to certain kinds of cars I use a draw bar or coupler shank of the usual length and do not change the place of attachment of the railthe frame of the railroad car. H

invention is fully described in the specification and shown in the accompany in which- 7 Figure 1 is a side elevation of a portion of a draft rigging embodying my invention.-

Fig. 2 is a top plan of a yoke and coupler and other parts. Fig. 3 is a vertical longitudinal section of an extension block on line 3-3 of Fig. 4.. Fig. 4 is a horizontal section of an extension block on line H of Fig. 3. Fig. 5 isa vertical longitudinal section on line 5-5 of Fig. 6. Fig. 6 is part top plan and part horizontal sectional view of the modification shown in Fig. 5.

Referring to the drawings,8 is a yoke of ordinary form.

10 is'a coupler shank or draw bar of ordinary length, which may be provided'with an ordinary coupler head, 9, and the rear end or butt of which coupler shank extends into an extension block, 11, preferably made integral with the block-like casting, ,13, which is'preferably made hollow, as indicated in Figs. 3 and- 4 at the numerals 14, and provided in its with reinforcing collars, bottom, the said casting being vertically with openings, 17, to receive 15, at its top and perforate the means, preferably rivets,

preferably hollow form 16,which attach the same to the yoke, 8. The coupler shank, 10, is provided near its rear'end with a transverse slot, 18, into which securely fits the removable coupler key, 19. The side plates, 12, are provided with slots, 20, also through which the coupler key, 19, passes. The coupler shank, 10, abuts at its rear end against the front face, 21, of the block-like casting, 13, and is held in place by means of the said removable key, 19, passing through the sideplates, 12. The extension block, '11, is preferably made with its forwardly extending side plates, 12, narrower vertically than the blocl -like end of said extension block, so as to provide shoulders, 22, into which the gibs, 23, of the yoke, 8, fit.

Fig. 5 is a modification of the'extension blockin which the side plates, 12, are'of a greater vertical width than the block-like portion, 13, of the extension block, to receive the rear end of a coupler shank, of comparatively greater dimensions and also illustrates a modification in which the side plates, 12, may be joined at either top or bottom by integral plates or pained at both top andbottom by integral top and bottom plates. 25, 26, thus forming a hollow box-like head,

27, projecting forwardly from the block-like .part 13 of the extension block, 11, to receive draw bar of usual length, the extension.

block,l?1, is attached to the ordinary yoke. 8, preferably by rivets, 16, being in the same manner usually employed to attach the coupler shank to the yoke. The coupler shank, 10, is then inserted into the forward part the extension block, 11, between its side plates 12 and attached. to the extension block .by means of the key, 19; thus the coupler.

head, 9, is extended forwardly from the position in which it is foundwhen the coupler shank is attached at, its rear end-directly to the yoke, 8. The modification in which the extension block is shown in Figs. 5 and 6 'provided with a hollow box-like head with a gib extending from the upper manner.

mits the coupler to be easily removed and,

replaced. a

I realize that, considerable variation is possible in the construction herein described 7 without departing from the spirit of my invention and therefore by the foregoing accurate description I do not intend to be limited thereto, except as pointed out in the following claims 1. In a railway draft rigging, in combination, a draw-bar, a draft yoke forwardly extension block being provided with forwardly extended lateral plates spaced apart,

having shoulders engaging said gibs, said to receive the draw-bar, the rear face of the draw-bar abutting the 'gibs of the yoke.

provided with inturned gibs, an extension block secured between the limbs of the yoke 2. In a railway draft rigging, in combinai tion, a U-shaped draft yoke, a draw-bar abutting against the free ends thereof, an extension block secured between the limbs of the yoke, a key, forward slotted extensions from said block spaced apart to receive the draw-bar, the key passing through the said extensions'and draw-bar.
