To all whom't may concern Be it known that I, Lnwis* T.l GARFIELD, a citizen of the United States, and resident of Chicago, county of Cook, and Stateof lllinois, have invented certain new and useful llmprovements in yDraft-Gear, of which the following is a specification, and which lare illustratedin the accompanying drawings, forming a part thereof.

The invention relates'to yokes or pockets for inclosing the shock absorbing elements for gear of a draft rigging, its object being to secure great strength coupled with simplicity ofpartsand ease of assembling.

The invention comprises a pocket in the forni of a continuous loop and a coupler engagin stirrup passing through the forward end 0 the loop and having its end members provided with suitable meanssuch as apertures and slots for receiving pins or keys for securing the stirrup to a coupler. lin' the accompanying drawings, Figure 1 is a view in perspective of the pocket and stirrup; Fig. 2 is a detail vertical longitudinal section through the stirrup and forn ward end of the pocket; Fig. 3 is 'a similar view showing a modilied form of construction; Fig. 4 is a sectional View on the line 4 4 ofFig. 3; and Fig. 5 is a view similar to Fig. 2, showing a further modification;

The pocket 10 is shown as oblong rectangular in form, but its shape may be varied as may be necessary to accommodate the particular construction of gear with which it is to be associated. As shown. in Figs. 1 and 2, this pocket isiwithout joint or seam, and may be made of cast or wrought metal. lThe vstirrup 11 is made of similar metal, is lli-shaped in form, its base being flat and its length being substantially equal to the `width of the pocket. rlhe side members 12, 13, of the stirrup project forwardly from the pocket when the parts are assembled. They are preferably tapering in form and are aperturcd, as shown at 14, 15, for the recep-l tion of a key whichwill also pass through a suitable aperture in the butt of a coupler when the latter is inserted between the stirrup sides. The sides of the stirrup may be strengthened by suitable ribs, such as those Specication et Lettera Patent.l

shown as extending along-their margins and surrounding the apertures.

In the construction illustrated in Figs. 3 and 4, the pocket 10 will be preferably made of a wrought metal strap bent to give lthe pocket its proper configuration, ythe ends of the st rap meeting along the median line of the forward end of the pocket, as indicated at 16, and being provided with short gibs 17, 18, which are folded inwardly. In this instance the base or cross memberv 19 of the stirrup is apertured, as shown at 20, to receive the gibs and thereby serve as a lock to hold the ends of the strap together and to prevent the spreading of its top and bottom members. In the construction illustrated in Fig. 5, the pocket 10 is shown as made of a wrought metal strap having its Vends moet ing on the median line of the forward end of the pocket and welded together, as represented at 21. The pocket member is adapted to receive any suitable shock-absorbing elements, whether springs or a combination of springs and friction members. The usual followers will be insertedand will normallyr bear against the rearward end of the pocket and the other against the cross member of the stirrup. The coupler, when secured between the side members of the stirrup will bear any buling against the forward end of the pocket and transmit bufiing stresses U-shaped lstirrup extending through the loop and having an'- aperture for receiving the gibs, the side members of the loop being adapted to embrace and engage a coupler.
