EMERGENCY DEAETeEAE.

ApplicationA led March 7, 1917. Serial No. 153,0'68.

To all whom t may concern:

Be it known that I, 4IRA S. DOWNING, a

citizen of the United States, residing at In-v dianapolis, in the county of Marion and State of Indiana, have invented certain new, and useful Improvements in Emergency Draft-Gears, of which the following is al specification.

The invention relates to emergency draft gear devices designed for use in case of accif It has for its. principal object; the provision of a simpley dent to the regular draft.

construction, (1) which can be easily and readily applied without returning the car to a repair point, (2) which shall be'sub-Y with it or to the cars with which the equipped car is used, and (4L) which shall be much more secure than the temporary repair means commonly used and which at the same time may be applied with only slighty delay and with the tools ordinarily available on a train. Certain embodiments of the invention are illustrated in the accompanying drawings, whereinl Figure 1 is a longitudinal section through one end of a car provided with my invention showing the coupler partially in side elevation and partially in section; Fig. 2 is a plan view of the coupler taken by itself; Fig. 3 is a side elevation view showing the application of a modification of the coupler to'a car; and Fig. t is a partial plan view of the construction shown in Fig. 3.

rEhe construction is designed to occupy the space ordinarily occupied by the regular draft gear and comprises a yoke adapted to be secured to the coupler shank and provided with means for attaching the coupler to the car truck or to the connection between the car truck and the car body. The construction is so designed that it may readily be applied upon removing the regular `draft gear and jacking up the body of the car slightly. After the emergency draft gear has been applied, it may be used an indenite period as it has substantially the strength of the ordinary draft gear. The car may, therefore, be

used as long as is desired before returning it Specification of. Letters Patent.

to the car. shops for the application of thev regular draft gear. Referring to the construction of Figs. 1 and 2, reference numeral 1 designates the lower portion of the car body carrying upon its under side the usual center sills 2lbetween the ends of which it is customary to mount the draft gear; 3 is the car truck havingthe end axle 1 and inner axle 5 and provided with the ybearing member-6opposingthe bearing member 7 carried by the car body;

and 8 is the usual pin extending throughthe bearing members 6 and 7.

The emergency draft gear comprises a yoke), preferably of cast steel, and havinga rearwardly extending shank or extension 10 formed so that'its rear end may fit between the bearing members'6 and-7. The upper` portion of the rear end of the extension 10 is recessed as illustrated, so as to interlock with the bearing member 7, andthe pin 8 extends through the two bearing members 6 and 7, and the interposed' end of the extension 10.

The forward end of the yoke 9 is providedv with a slot, and the `shank 11 of the coupler may be secured in the yoke by means of a key '12 extending throughl the. slotted yoke and through the rear end ofthe coupler shank. The coupler and itsfshank may be of the ordinary standard type.

In orderto provi le for the support of the.

yoke from beneath, the strut13 is employed, such strut beingv secured at its forwarclend to the yoke by means of the p in 14.. The rear of the strut 13 is secured to the end axle 4 of the truck by means of the two-part axle collar 15 and the bolt 16, such bolt 16 extending through the lugs carried by the collar. Lying inside the collar is a bushing 17 of cast iron or other relatively soft metal. kThe strut 13 not only serves to supportth'e yoke against downward movement but also reinforces the holding action of the extension 10 when the yoke is either in compression or under tension. The` lower portion of the yoke carrying the pin 14 'is also provided with a shelf 19 extending beneath the shank of the coupler-and the position of the cou* pler shank may be adjusted vertically by means of the insertion of wedges or plates 20 of wood or other material.

described, the regulation draft gear is fir removed from the car after the Patented May 29, 1917.

19,5... In applying the emergency gear as abovef.v

body is Vjacked up to separate the bearing members 6 and 7 and the yoke is positioned with its rear end between the bearing members 6 and 7, at which time the ller plate 18 is also inserted to increase the bearing surface upon the lower side of the end of the extension. The pin 8 is then applied and the strut 18 is secured to the axle 4, thus completing the installation of the yoke to which the coupler shank may be attached in the manner heretofore described.

Figs. 3 and 4 illustrate al modification wherein the yoke is built up of'wrought metal straps and wood, the general construction being along the same lines as the first type of constructionv except that the strut is replaced by support which bears 'con' of the end axle.

As illustrated in Figs. 2 and 3, the yoke comprises a pair of sections 2l and 22 with the interposed wood block 23, the forward ends of the members 21 and 22 being riveted to the rear end of the coupler shank 24. rIhe rear end of the plate or strap 22 is extended and lies between the bearing members 25 and 26 carried respectively by the truck and car body, a pin 27 being extended through the end of the plate 22 and the two bearing members. The support upon the axle 28 of the truck is formed by the two straps 29 and 30 riveted in position as illustrated, so that the coupler mechanism is supported from beneath by the axle 28. The improvement might be embodied in a number of different forms but the foregoing will be suflicient to illustrate the principle of 'the invention. Y

`What I claim is:

l. In combination, an emergency draft gear, comprising a coupler holding member adapted to occupy the space between.

the draftsills of a car, an extension secured at its rear end upon the car truck, and a strut between the end axle of the truck and the said member.

2. In combination, an emergency draft gear, comprising a coupler holding member adapted to occupy the space between the draft sills of a car, an extension secured at its rear end at the connection between the car truck and body of the car, and a strut between the end axle of the truck and the said member.

3. In combination, an emergency draft gear, comprising a yoke adapted to occupy the space between the draft sills of a car, an extension with its rear end encircling the truck pin, and a support between the yoke and the front axle of the truck.

4. In combination, an emergency draft gear, comprising a yoke adapted to 'occupy the space between the draft sills of a car, an extension secured at its rear end at the connection between the car truck and body of the car, and a strut secured at its front end to the yoke and provided at its rear end with securing means encircling the end axle of the truck.

5. In combination, an emergency draft gear, comprising a yoke adapted to occupy the space between the draft sills of a car, an extension secured at its rear end at the connection between the car truck and body of the car, a collar encircling the end axle of the truck, and a brace between such collar and the yoke.

6. In combination, an emergency draft l gear, comprising a yoke adapted to occupy the space between the draft sills of a car, a rearward extension for the yoke having its rear end clamped between the car truck and the body of the car, and a support for the yoke upon the end axle of the truck.
