CAR COUILER.

Application filed July 19, 1924. Serial No. 726,913.

To all whom itmag concern:

Be it known that I, PnRoY B. CAMP, a citizen of the United States, and resident of Maywood, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Car Couplers, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to car coupling devices and has for its principal objects to provide a connection between the locking pin and the operating lever that can be readily applied to existing cars as well as to new cars; that will endure the stresses and strains of use and abuse, and that will accommodate itself to all the necessary movements between the coupler head and the operating lever. Further objects and advantages of the invention will become apparent as the disclosure proceeds and the description is read in connection with the accompanying drawings illustrating a selected embodiment of the invention and in which F ig. 1 is an end elevation of a fragment of a car with the invention applied thereto;

Fig. 2 is a side elevation of a similar fragment of a car;

Fig. 3 is a perspective view of a link made according to the invention before it is assembled with the other parts, and

Fig. 4 is a similar perspective view of a' link assembled with fragments of the operating lever and the locking pin.

Coupling devices usually include a looking pin such as that shown at 10, slidably mounted'in a coupler head 11 carried by the draw bar 12 suitably connected with the car 18. An operating lever 14: is rotatably mounted in bearings 15, has a hand arm 16 and a lifting arm 17, the latter being equipped at its end with an eye 18 located above the eye 19 of the locking pin 10.

According to the present invention the arm 17 and the pin 10 are connected by a link 20 looped through the eyes 18 and 19. Preferably this link is constructed as shown in Fig. 3, comprising a rod having a substantially straight portion 21 reversely bent at 22 and 23. Below the bend 22 one end portion of the rod is formed into an eye 24 and above the bend 23 the other end portion is inclined laterally, as indicated at 25 and provided with an eye-forming bend, or member, 26, lying in position to extend through the eye 24 when the portion 25 is moved to'the dotted line position, shown in Fig. 3.

In assembling, the eye-forming member 26 is first threaded through the eye 18, then through the eye 19 and then the part 25 is forced to take the dotted line position in F 1g. 3 after which the eye-forming member 26 is bent to the form shown at 27 in Fig. 4. By proceeding in this manner an extremely strong and serviceable connectionis made between the operating lever and the locking pin. The strains developed by jerking on the hand lever 16 are resisted first by the reverse bends 22 and 23, and only stresses produced after these bends yield are brought to bear upon the interlocking eyes by which the link 20 is closed. At the same time the link is very readily assembled with the operating arm and the locking pin, and will permit all the necessary movements between the two in the operation of a train. In some coupling devices the eye 18 lies in a vertical plane, but it can be easily brought to the horizontal plane by twisting the arm 17 and hence the invention is easily applied to those coupling devices also.

The link may take Various forms in compliance with individual preference, but it will always be of advantage to make use of the inclined portion 25 to place the eyeforming member 26 in position to engage the eye 24:, for in this way the ends of the link are brought together by an easy twisting movement in the region of the bend 23.

Use has been made of specific description and illustration in order to disclose the inv vention. but it is intended that nothing contained herein shall unnecessarily limit the following claims, or require a construction thereof that would permit the substance of the invention to be used without infringement.

I claim as my invention 1. In a device of the class described, a coupler, a locking pin having an eye at its upper end, an operating lever including a crank arm having an eye located above the eye of the locking pin, and a rod looped through said eyes and having interlocking reverse bends at its ends.

2. As an article of manufacture, a link for car uncoupling mechanism comprising an open loop formed from a single piece of material having an eye member at one end" and provided at its other end with an eye cludes forming an elongated link Open at forming member arranged laterally With reone side and provided With a closed and an 10 spect to said eye member whereby, When the Open eye, threading the link through the ends of said 100p are bent to occupy subeye of the pin and the lever, engaging the stantially the same plane, said members Will open eye with the closed eye and forcing it inter-engage. closed.

3. The process of connecting locking pins and operating levers of couplers Which in- PERCY B. CAMP.
