. CAR-COUPLING.

SPECIFICATION forming partA of Letters Patent No. 59736175, dated January 18, 1898.

Appiicatgn ld September 22, 1897. Serial No. 652,619 (No model) To @ZZ 107mm it may c07tcer7t.. l Be it known that I, JOHN LINDEN, a citize of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Car-Coupling, of

which the following is a speciiication.

The'invention relates to improvements in cancouplings.

The object of the present invention is to improve the construction of'car-couplings of the Janney type, more especially the mechanism for locking and releasing the knuckle, and to provide a car-coupling which will be closed at the top and sides to prevent the accumulation of ice or other matter which might interfere with the operation of it.

A further object of the invention is to provide a car-coupling adapted to couple autoinatically and capable of being readily uncoupled without going between cars.

Another object of the invention is to provide an operating mechanism for releasing the knuckle which will not interfere with the longitudinal play of the draw-head.

The invention. consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out inthe claims hereto appended.

In the drawings, Figure l is a perspective view of a car-coupling constructed in accordance with this invention and shown applied to a car. Fig. 2 is a horizontal sectional view. Fig. 3 is a transverse sectional view. Fig. 4 is a detail perspective View of the weighted bell-crank-locking lever.

Like numerals of reference designate corresponding parts in all the figures of the drawings,

1 designates a knuckle pivoted to a drawhead 2, at one side thereof, in the usual manner by a knuckle-pin 3, which is secured in place by a split key 4, passing through a perforation of the llower end of the knuckle-pin and located beneath the draw-head. The knuckle is provided With a slot 5 and perforations 6 to enable it to receive an ordinary link and pin, and its arm 7 is beveled at its at its angle on a longitudinal pin or pivot 12, is disposed transversely oi' the draw-head within the saine, and its horizontal arm l0 is beveled at its vlower edge at its front face to enable it to be readily lifted by the arm of the knuckle. The end of the horizontal arm 10 of the lever abuts against the front or outer face of the arm of the knuckle when the latter is closed and locks it inits closed position, and it is adapted to be swung upward out of engagement with the knuckle to release the same, which is automatically thrown open by a spring 13 when released. The other arm of the bell-crank lever depends through a slot 14 of the bottoni of the draw-headand is connected with an ,operating-rod 15, disposed transversely of a car 16 and having its outer end, supported by a bracket 17. The sides and top 'of the draw-head are closed, as illustrated in the accompanying drawings, and accumulation of ice and other matter which might interfere with the operation oi' the carcoupling is thereby prevented.

The operating-rod 15, which is provided at its outer end with a handle-loop, is adapted to be drawn outward to swing the weighted arm of the bell-crank-locking lever upward, and the bracket, which is provided with a horizontal loop 17, permits the inner end of the rod to have sufficient play or swing to permit the longitudinal play of the drawhead. The bottom of the loop is provided near its outer end with an upward bend 1S, forming an outer eye, which is adapted to receive the operating-rod and hold the same in convenient position for instant use.

The shank or draw-bar of the draw-head is provided with a horizontal slot 1S and ver tical perforations 19, and its lower face-is recessed in order to adapt it to be. readily conneeted with the various forms of draft mechanism. i

The invention has the following advantages: The car-coupling is automatic in operation and couples and uncouples Without necessitating a train -hand going between cars. The operating mechanism is exceedL ingly simple and is unaffected by the longitudinal play of the draw-head. It dispenses with chains and other lifting mechanism for raising a locking-pin and prevents injury to such rigging resulting from its connection to IOO the draw-head and the car-body. The sides and top of the draw-head are closed, soV that moisture is excluded and the accumulation of ice is prevented.

Changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacricing any of the advantages of this invention.

That I claim isl. In a car-coupling, the combination of a draw-head, a knuckle, a locking-lever engaging the knuckle, the bracket designed to be mounted on the car and provided with ahorizontal loop having an upwardly-extending bend at its bottom to form an outer eye, and a transverse operating-rod arranged in the loop of the bracket and connected With the locking-lever, substantially as and for the purpose described.

2. In a car-coupling, the combination of a draW-head, a knuckle pivoted to the saine at one side thereof, a transversely-disposed bellcrank lever fulcrurned at its angle Within the draw-head at the opposite Side thereof, and having one arm beveled at the lower front edge and arranged to be lifted by the arm of the knuckle and adapted to engage the same,

said lever having `its other arm extending throufghthe bottom of the draw-head, and operating mechanism connected With the depending arm of the lever, substantially as described.

3. In a car-coupling, the combination of a draW-head,a knuckle, a transversely-disposed bell-crank lever fulcrumed Within the drawhead and having one arm arranged to engage the arlnof the knuckle, the other arm of the lever being extended through the bottom of the 'draw' -.head, a bracket designed to be mounted on a car and provided with a horizontal loop having an upwardly-extending bend at its bottom to form an outer portion or eye, and an operating-rod arranged in the loop of the bracket and connected with the depending arm of the lever, substantially as described.

In testimony that I claim the foregoing as my oWnI have hereto affixed my signature in the presence of two Witnesses.

JOHN LINDEN.
