JAMES S. FISHER, OF BALTIMORE, MD., ASSIGNOR TO B. BERNARD BROWN E AND GEORGE F. ADAMS, OF SAME PLACE, ONE-FOURTH TO EACH.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 225,583, dated March 16, 1880. Application filed J annary 20, 1880.

To all whom it may concern Be it known that I, JAMES S. FISHER, of the city of Baltimore and State of Maryland, have invented an Improved Oar-Coupler, of which the following is a specification; and I do hereby declare that in the same is contained a full, clear, and exact description of my said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to certain improvements in that class of car-couplers which are specially designed to admit of the coupling and uncoupling of cars with safety, the presence of an attendant between the platforms of the cars not being necessary to perform the operation of connecting and disconnecting the coupling-link.

In the description of my said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which 7 V Figure I is an exterior side view of the improved coupler. Fig. II is a plan of the invention. Fig. III is a cross section of the coupler on the dotted line w y, Fig. I.

Similar letters of reference indicate similar parts in all the views.

A is a bar bent so as to form the frame of the coupler. The ends of the bar A are affixed to a plate, 13, the central portion of which is removed to allow of the insertion to the coupler of the coupling-link G. V

The sides of the coupler are slotted where they extend from the plate B to accommodate the coupling-link, which in width is greater than the frame.

D is a hook, secured by means of a bolt, a, within the frame. The bolt to is on a horizontal dotted line marked 12 w, which passes through the coupling-link and a point about the center of the projection bet the hookD, the face of which projection is at aright angle with the said line. 7

The position of the'bolt a with reference to the projection b and the link, as described,

while it counteracts the tendency of the hook to automatically alter its position and release the coupling-link, also admits of the uncoupling of the link when moderate power is applied to the hook in the proper direction, the hook being practically lengthened as it is elevated. A stop, 0, may be used to prevent the hook being raised higher than is necessary to release the link.

The mechanism for operating the hook D consists of a curved bar, E, hinged to the free end of the said hook, and a lever, F, which is pivoted to thesaid bar in such manner as to allow of its being thrown over sidewise to not interfere with the passage between the platforms of the cars. l

The end of the curved bar, where hinged to the hook, isfurnished with a projection or flat tened surface, as shown in the drawings, in order that the said bar and its lever can only be moved in one direction-via, that indicated by the arrow when the hook is in place. 7 The curved bar E, when the lever Fis pulled back, lifts its end which bears upon the coupler, sliding thereon and forming a movable fulcrum for the lever.

The object of this construction is to enable the person uncoupling to uncouple without the necessity of pulling directly up from the hook, the work being facilitated by the leverage gained.

I do not claim, broadly, a car-coupler having a frame formed of a slotted bar combined with a pivoted hook for securing the couplinglink, as such combination is not new but What I claim is The slotted bar A, bent to form the frame of the coupler, and having the end perforated plate B affixed thereto, combined with the hinged hook D, curved bar E, and lever F, all constructed and arranged for operation. substantially as set forth. 7 1
