SAR-COUPLING.

SPECIFICATION forming part of' Letters Patent No. 477,561, dated Ji une 21, 1892. Application filed January 29,1392. Serial No. 419.723. (No model.)

.To all whom it may 00u/cern:

Be it known that I, HENRY LESLY, a citizen of the United States, residing at Birmingham, in the county of .letterson and State of Alabama, have invented a new and useful Improvement in Car-Couplers, of which the following is a specification.

My invention relates to improvements in self-couplers; and the object of my improvement is: lirst, to Aprovide a coupler that will be self-connecting by two ears coming in contact with each other; second, for uncoupling while there is a strain upon the coupler without going between the cars; third, to provide a hook of such form as to prevent draw-heads from falling to the ground when pulled out by breakage or other accident. I attain these objects by mechanism illustrated in the aecompanying drawings, in which Figure l is an isometrical viewof a pair of couplers connected', as in use. Fig. 2 is an isometrical sectional view of Fig. I at dotted lines A A, showing the special form and construction of internal mechanism.

Similar letters referto similar parts th roughout the several views.

l) is a east-metal casing cored to receive lock-block t, with rod f, (connected therewith or made a part thereof,) and coupling-hook C and spring 7L, furnished with partition or wall J.

C is a cast hook with a slot and hole Z, as shown in Fig. 2, for holding ordinary link and pin, when used in connection with oldfashioned link draw-heads, and swings on pin 7s when disengaged from block g in order to unccuple from draw-head of corresponding form, also furnished with lip or extension d at its lower extremity.

CZ is a lip or extension at the lower extremity of hook C for the purpose of preventing opposite draw-head from falling to the ground in case of drawbolt breaking or an accidental loosening from car.

e is a lever passing through a slot in rod f and held in place by a pin or bolt through end next to casing b for the purpose of disengaging block g and hook. C when uncoupling, and is operated by pressing forward at end farthest from casing in the direction of hook C, the edge of cover m acting as a fulcrum, thus compressing spring h and drawing block g from hook C, releasing same, which swinging on pin 7o will uncouple from opposite drawhead. In coupling, the opposite draw-heads coming in contact with each oth er, the hooks C being disengaged from blocks g and swung outward, press each other toward the center, the back end of hook C presses against a correspondingly rounded or beveled end on block g, forcing the same in the direction of spring 7L, which it compresses until they can pass eachother, when spring 7i expands, returning block g to its former position, holding hook C locked until released by means of lever e.

I am aware that prior to my invention, couplers have been made that were selfacting and could be released without going between the ears. I do not therefore claim such a combination, broadly; but

What I do claim as my invention, and desire to secureby Letters Patent, is-- l. In a car-coupler, the hook C, formed with a lip or extension that will prevent the opposite draw-head from falling to the ground when accidentally drawn from the opposite ear.

2. The combination, in a car-coupler, of the lever e, operated by a forward movement over a short fulcrum to obtain increased leverage for tjifncoupling under strain, with block g and rod 3. In a car-coupling, the block g, provided with the beveled front face and the plain rear face corresponding in width with the tail of the hook, in combination with the wall .I within the coupling-head and the spiral spring h and suitable means for actuating` the said block, all substantially as described.

HENRY LESLY.
