CAR- COUPLING.

Specification of Letters Patent.

Patented Apr. 8.1913.

Application filed March 14, 1912. Serial No. 683,683.

To all whom it may concern:

Be it known that I, BENJAMIN H. BUR-- NETT, a citizen of the United States, re-

siding at Columbus, in the county of Frank- 'lin and State of Ohio, have invented certain new and useful Im rovements in Car- Couplings, of which t e following is a specification.

The object of this invention is to provide an improved car couplingof the J anney type and in which the locking pin can be set forpermitting the separation of they cars and afterward further manipulated for I opening the knuckle'to automatic coupling on the line wm Fig. 1 showing the locking pin supportedpart way up. Fig. 3 is a similar view on the line 2--2 showing the in down. Fig. 4. is a plan view of the l ower side of the coupling. Fig. 5 is an elevation of the left hand side of the coupling. Fig. 6 is a view of the left hand side In the views 10 designates the draw bar which is provided with a head '10 having a suitable cavity in its forward end to receive operative parts. On the head at the left hand side of the cavity are two perforated projections 11 and 11 to receive vertically alined pivoting pins 12 and 12 on corresponding projections on the knuckle l5.- The projections 11 and 11 are spaced sufliciently apart to permit the pins 12 and 12 to be centered over and inserted into the perforations in the projections 11 and 11 while the knuckle is opened -to more than normal. The lower pin 11 is made long enough to project below the ear where it has secured to it a keeper 13 in such position that said pin will abut against a stop 14 on the lower side of the head and prevent the knuckle from turning so far from open position as to render it liable to be lifted off the projections 11 and 11*.

The knuckle has an inwardly projecting tail piece l5 from the lower side of which projects a pin 15". Pivoted at- 16 in the rear wall of the cavity of the head is a lever or kicker, so called, that has at one side a curved arm 17 reaching behind the pin 15 and at the other an angular arm l7 reaching forwardly in proximity to the right hand side of the locking pin. The locking pin includes a shank port-ion 18 that extends upwardly through a vertical hole 10 in the draw head and is accessible for manipulation at the upper side of the head. At its lower endthe locking pin is provided with a blade-like member 18" extending rearwardly in a plane inclined to thevertical plane of the axis of the draw bar, and said blade has an inclined edge 18 that, when the pin is raised, is adapted to act on the angular arm of the kicker and throw the arm 17 forward. A suitable opening in the lower side of the draw head is Provided, as shown, for the operation of the said blade. The locking pin is also provided with a lateral tooth 18 adapted to rest on a tooth 10 on the wall of the cavity where the pin works.

In Fig. 2 the locking pin is shown as raised and supported by the superposition of the tooth 18 on the tooth 10. This position of the pin can be had when the knuckle is in closed position, as shown in Fig. 1 and while two couplers are coupled and it is desired to separate the cars. It is obvious that in this position of the parts the knuckle can be pulled out to open position, as shown by broken'lines Fig. 1. If afterseparation of the carsthe knuckle be not in proper open posit-ion for'coupling that member can be thrown to proper open position by rais-, ing the pin to actuate the kickerthereby' causing the arm 17 to operate on the pin 15 and throw the knuckle to full open position. When the knuckle has been thus turned out the pin is lowered to rest on the tooth 10, and when the open knuckle of another car enters the coupling so placed the angular arm of the kicker by the action of the pin 10 on the arm '17, unseats the locking pin permitting it to drop to position to lock the knuckle from opening at all. The locking pin has a shoulder 10 to support it in low ered position. i

What I claim is:

In a car coupling, the combination of a draw head having a suitable cavity, a knuckle having a tail to work horizontally into said cavity, a lever having two arms 17 and 17 fulcrumed to swing horizontally in said cavity,'the arm 17 to engage the tail 2Q: onnie? 1 of the knuckle, a vertically and rectilineeifly i raised position to permit the opening of the sliding locking pin 18 having a tooth 18 I knuckle, the arm 1? 0f sai'cl lever being actuon its shank and n blade-like member 18 ated by the tail of the knuckle to throw the at its lower end, said blade-like member haw arm 1'? directly against the locking pin to 5 ing an inclined eclge 18* which When raisell i'eleaee the same to knuckle locking position 15 acts on the arm N of said lever to throw when the knuckle is closed.
