DRAFT-HIGGINS 1 9B RAILWAY-CARS.

Specification of Letters Patent.

Patented Mar. 2, 1915.

To all whom it may concern Be it known that we, CHARLES B. YOUNG and Gmrn G. GILPIN, citizens of the United idtates, residing at Aurora, in the county of Kane and State of Illinois, and Riverside, in the county of Cook and State of Illinois, respectively, have invented a certain new and useful Improvement in Draft-Rigging for Railway-Cars, of which the following 1s a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specltication.

Our invention relates to improvements in draft rigging for railway cars.

The object of our invention is, to provide a draft rigging for railway cars of simple construction and etficient operation.

In the drawings forming a part of this specification, Figure 1 is a plan view of a draft gear yoke forming a part of the draft rigging embodying our invention; Fig. 2 1s a side elevation of a draft rigging embodying our invention; Fig. 3 is a vertical longitudinal section of the frontendthereof; Fig. -l is a cross section taken on line 4-4 of Fig. 2; Fig. 5 is a cross section taken on line 55 of Fig. 2; and Fig. 6 is a perspective view of one of the locking members employed in connecting the draw-bar to the draft yoke.

Referring to the drawings, the numeral 7 indicates a draw-bar, the rear end thereof only being shown in the drawings, having a' butt S provided with the usual vertical rivet holes 99, and having the oppositely arranged shoulders lO--1O thereon. The draft yoke 11 has an upper limb 12, lower limb l3, and a rear member ll connecting the said limbs at their rear ends, and a forward connecting member 15 having an opening comprising the vertical plates 1616, preferably integral with the limbs of the yoke, and spaced apart, forming an opening 17 adapted for the passage of the draw-bar. The upper and lower limbs of the yoke are provided at their forward ends with the 1nturned gibs at6 l6, the rear faces thereof being preferably concave to receive the forward convex ends 47 of the upper and lower locking members 18 and 19, respectively. The locking members are oppositely arranged upon the draw-bar, each being provided with in-turned gibs 20 forming shoulders 2121 adapted to engage against the shoulders 10 of the draw-bar. The locking members are each provided with a perforation 22, the said perforations registering with one of the rivet holes 9 through the draw-bar to receive a key or pin 23, which is adapted to hold the locking members in position upon the upper and lower faces of the draw-bar, and to prevent accidental displacement therefrom. ln connecting the draw-bar to the yoke, the draw-bar is eX- tended rearwardly through the forward opening 17 in the yoke, and turned laterally, as illustrated by the dotted lines indicated by the numeral 24 in Fig. 1 of the drawings. When so positioned, the locking members are placed in engagement with the draw-bar, and secured against lateral displacement therefrom by the insertion of the pin or key 23 through the draw-bar and locking members. The draw-bar is then drawn forwardly, and in its operative position in connection with the yoke is adapted on forward movement to draw the yoke forwardly through the engagement of the locking members against the yoke.

On rearward movement of the draw-bar, the draw-bar and locking members slide rearwardly in the yoke. The yoke is provided with front and rear pockets, and is of the type adapted to be employed with tanelem-arranged draft gear units, the front pocket 25 in the yoke being separated from the rear pocket 26 by a vertical thimble 27, which is preferably integral with the limbs of the yoke. Within the front pocket 25 is mounted the front follower 28 and the front intermediate follower 29. Between the followers is mounted a compression resisting member, consisting preferably of an outer spring 30 and an inner spring 31 nested therein. The front intermediate follower is provided with a perforation 32 adapted for the passage of a plunger 33, the plunger at its forward end engaging the front follower and extending through the: thimble 27 and engaging against the front face of the rear intermediate follower 34. The rear intermediate follower 34, the rear follower 35, and the rear compression resisting member, comprising preferably the outer spring 36 and the inner spring 37 nested therein, are mounted within the rear pocket 26 of the yoke. The thimble 27 is formed integrally with the yoke and comprises a longitudinally extending centrally located vertical web 38,

and a pair of transversely extending,- vertical webs 41-41 at the ends of the web 38, said webs l1 being notched or recessed to coincide with a recess formed in the web 38 by means of a U-shaped portion 39 whereby the plunger 33 may be inserted and Withdrawn by moving the same laterally with respect to the yoke. In preferable con- 7 struction, the yoke is provided with a strengthening rib 42 extending along the outer faces of the limbs and rear connecting member, and being preferably integral with pression resisting member in the rear pocket against the rear intermediate follower.

On rearward movement of the draw-bar, the front follower is forced rearwardly by the draw-bar compressing the front compression resisting member against the front intermediate follower 29, the Plunger 33 being forced rearwardly by the front follower and compressing rearwardly the rear intermediate follower 34, which compresses the rear compression resisting members within the pocket '26 in the yoke against the rear follower 35.

In assembling the compression resisting parts within the yoke, it will be apparent that the plunger 33 may be inserted later- 40 ally into its position in the thimble 2? with thefront intermediate follower 29 in its position upon the plunger.

We claim 1. A tandem yoke for railway draft rig- 45 gin'gs, comprising upper and lower arms connected at the rear and an intermediate integral thimble, said thimble comprising longitudinally and transversely extending vertical webs provided with a recess open at the side to permit the insertion and withdrawal of a rod or plunger from the side of the yoke.

2. In a draft rigging for railway cars,

the combination with a draw-bar, front,

front intermediate, rear, and rear intermediate followers, compression resisting de; vices between the followers and a plunger N extending from the front follower to the rear intermediate follower, of a tandem yoke having an intermediate thimble provided with a recess on the side thereof in which recess said plunger operates, the plunger being removable from said recess from the side of the yoke.
