CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 449,633,,dated March 31, 1891.

Application filed December 5, 1890- Serial No. 373,684. (No model.)

To all whom it may concern:

Be it known that I, FRANK MILLER, a citizen of the United States, residing at Batesville, in the county of Noble and State of Ohio, have invented a new and useful Car- Coupling, of which the following s a specification.

This invention relates to car-couplings; and the object of the same is to effect improvements upon couplings of this same general character heretofore constructed.

To this end the invention consists in the details of construction hereinafter more fully described and claimed, and as illustrated in the drawings, in which- Figurel is an elevation of the end of a boxcar, showing my improvements as applied thereto. Fig. 2 is a central longitudinal section of the draw-head in its normal position without the link. Fig. 3 is a similar section with the pin raised to release the link and the link supported by the link-lifter. Fig. 4 is'a similar section showing the linklocked in position and under tension.

Referring to the said drawings, the letter O designates the body of the car, below which is arranged a draw-head I which is of the ordinary construction, except as hereinafter specified. Mounted in eyes H in the ends of the car-body is a horizontal rod h, having depending ends h and anupwardly-extending handle 7L2. Depending from this rod is a lever K,'which is connected with the pin J in a manner hereinafter described, and connected to the end of the car is a spring M, preferably of the construction shown, which bears upon the lever K and forces it normally inward.

g is. a cleat secured to the end of the car, and pivotally mounted on a pin G therein is a lever 2', one of whose ends is connected by a chain S with an eye P in the top of the draw-head. By this means an operator standing by the side of the car can manipulate the lever '11 to raise and lower the draw-head for the purpose of guiding the link 'into the mouth of an approaching draw-head.

Pivotally mounted on a horizontal bolt S through the draw head is the link-lifter D, which is of the shape shown in the drawings.

In eyes 0 in the bottom of the draw-head is mounted a bar E, around which are passed the coils of a springF, whose free end presses downwardlyon the rear end of the link-lifter and throws its front end upwardly. Said front end is provided with a notch N, whose rear approach a is beveled, as shown, and the notch passes over a square bar Q, which is seated through the draw-head. The spring F causes the front end of the link-lifter to be normally raised, as above stated, and the link T is therefore normally held in direct alignment with the draw-head, as shown in Fig. 3, exceptunder conditions hereinafter stated.

The letter J designates the pin, which is of L shape, pivoted at its angle on a bolt Q, passing transversely through the draw-head, and the upper end of this pin is connected by a link L with the lower end of the depending lever K. By reason of the fact that the spring M bears this depending lever K to the rear the upper end of the link J is also borne in that direction and the lower end thereof normally thrown downward through the link.

As the latter is driven intothe draw-head, the

pin is turned to the rear on its pivot Q and the link-lifter D is slightly depressed.

tension beingimp'arted to the link,the pin is drawn forward until its lower end rides up the beveled approach a and depresses the link-lifter D, as shown in Fig. 4:, the lower end of the pin then striking the square bar Q and firmly holding the link. A continued tension upon the link will hold the parts in this position with the front end of the linklifter depressed and out of contact with the link, whereby the latter will be allowed a limited amount of play in all directions, ac-

cording as the exigencies of the case may deceases the link-lifter will rise and the link will be rigidly held, as shown in-Fig. 3. The pin may be then. raised by operating one of the ends it or the handle 7L2 from either side or from the top of-the car. The advantages .mand. As soon as the tension on the link be made therein Within the skill of a mechanic without departing from the spirit or scope of the invention.

\Vhat is claimed as new is 1. I11 a car-coupling, the combination, with a draw-head loosely supported beneath the car, a lever pivoted to the end of the ear, and a chain connecting said lever with the draivhead, of a pin pivoted in said draw-head, a shaft journaled across the end of the car and carrying operating-handles, a lever connected to and depending from said shaft, and a link connecting said lever with the pin substantially as described.

2. Ina ear-coupling, the eombi11ation,witl1 a draw-l1ead, a spring-actuated link-lifter pivoted in the bottom of said draw-head and having a deep notch in its upper face, Whose rear approach is beveled, and a bar through the draw-head normally resting in said notch, of a pin pivoted in the upper side of the draw-head with its lower end normally in contact with said approach, and means for oper ating said pin, substantially as described. i In a ear-coupling, the combination, with l a draw-head loosely supported beneath the car, a lever pivoted to the end of the car, a chain connecting said lever with the drawhead, a spring-actuated link-lifter pivoted in the bottom of the draw-head and having a deep notch near its front cnd in its upper face, the rear approach to said notch being beveled, and a bar through the draw-head resting in said notch of a pin pivoted in the upper side of the draw-head with its lower end normally in contact with said approach, a pin-operating lever. a spring" pressing the same to the rear,a link connecting the lower end of said lever with the coupling-pin, and handles for operating said lever, all substantially as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as myown I have hereto affixed mysignature in presence of two witnesses.
