SAFETY DEVICE FOR CAR-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 629,923, dated August 1,1899. Application filed time 13,1899. $erial No. 708,812. on model.)

To all whom, it may concern:

Be it known that I, J OHN DANIEL Boone, a citizen of the United States, and a resident of the town of Union, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in-Safety Devices for Oar-Couplers, of which thefollowin g is a specification, reference being had to the accompanying drawings,forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to safety devices for car-couplers, and has for its object to provide simple and efficient means for preventing vertical disengagement of two interlocked coupler-heads if one of said heads 'shouldbe disengaged from the car by breakage or other cause. V

My invention is designed to obviate all danger of accident to cars in rear of a broken or disengaged coupler, by reason of the fact that with my improved safety device the broken or disengaged coupler-head will be supported by theadjoining coupler-head, and thus prevent it from falling beneath thecars.

The invention will be hereinafter fully described, and specifically set forth in the annexed claims.

In the accompanying draw'ings,forining part of this specification, Figure lis a plan view showing two interlocked couplers provided with my improved safety device. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of a detail of my invention.

Referring to the drawings, A designates an upright or post, which is provided upon the top of the draw-head B. This post is prefercoupler;

pointimmediately in rear ably arranged at a by .which the knuckle d is of the pivot-pin c,

pivotally connected to the jaw of the couplerhead when my improved safety mechanism is applied to car-couplers of the twin-jaw or Janney type.- be noted that I have herein illustrated my invention in connection with a Janney-type but I do not restrict myself-to such specific'use, and it will be understood that the safety device will be applied'to any form or type of coupler to which it is adapted. The post A is carried upon a horizontal'base e, provided with an eye or opening through which the hinge-pine isadapted to pass, the

In this connection it will i relative construction and arrangement being preferably such that the head g of the pin 0 rests upon the base e and serves to retain the'latter and its post A in connection with the draw-head and in normal position; I do not, howeveiyldesire to limit myself to this manner of securing the base and its post in position; but in couplers where no pivot or hinge pin is employed the base can be bolted or otherwise secured to the draw-head in any suitable-or adapted manner.

H designates an upright which is secured by bolts, as at t, or in any other suitable maniner, to the top of the draw-head B ata point in rear of and to one side of the post A. This post H carries a horizontal forwardly-projecting arm J, provided at its outer end with a ring or loop 75, as shown. It willbe understood that one post device A and one arm device J are provided upon each coupler-head,

so that said devices upon the respective coupler-heads are relatively located opposite to each other on a transverse plane, as shown in Fig. 1 of the drawings. The ring or loop 7: therefore comes directly over the post A of the opposite draw-head when the parts are in normalposition and the coupler-heads are in terlocked. The projecting arm J can have a hinge connection with the post H, if desired, as illustrated by Fig. 3 of the drawings, so that the arm can be swung back out of operative position under any circumstanceswhich would make this requisite, and it is maintained normally in horizontally-extended position by means of a plate-spring h.

The operation and advantages of my invennary independent vertical movement of the coupler-heads is not interfered with; butshould either coupler-head become accidentally disengaged from' its car the same will drop until the ring 76 will encircle or engage the post A of the opposite coupler-head, and the disengaged coupler-headwill thus be suspended and carried without danger of its falling on the road-bed or dropping beneath the cars. V

I do not confine myself'to the details of mere mechanical construction and design as herein shown and described, as it is obvious that underthe scope of my invention I am entitled to structural variations.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As a means for preventing vertical disengagement of car-couplers, the combination of an upright or post and a projected arm, said arm being provided with an end ring or loop, whereby the coupler may be suspended from the arm by means of an engagement of said' ring or loop with said upright or post,

'substantiallyas shown and described.

a base-piece, and a projected arm carried by an upright and provided with an end ring or loop, the said parts being secured, to the upper surface of the coupler, substantially as shown and described.

4. As an improvement in safety devices for car-couplers, the combination, with an upright or post secured upon one coupler-head, of a projected arm secured upon the opposite coupler-head, and adapted to engage said upright or post, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in pres- 1 ence of two witnesses, this 6th day of March,

JOHN DANIEL ROCHE. Witnesses:
