|MPRovMENT IN cAR-couPLlNc-is.

i Specification forming part of Letters Patent No. 149,574, dated April 14, 1874 application filed March 27, 1874.

To all whom it may concern: Be it known that we, SILAs V. GARPENTE and GHAUNCEY l?. CARPENTER, of Wellington, county of Lorain, State of Ohio, have invented a certain new and useful Improvement in Car- Couplings, of which the following is a full description, showing ythe construction and operation thereof, reference being had to the accompanying drawing.

The object of this invention is to render the coupling of cars automatic; to provide for the setting of the coupling-pin from the top or sides of the cars, and to insure coupling when the draw-heads are at different heights. y

Figure 1 represents a side view of the device, the coupling-pin and slide being in position for coupling 5 Fig. 2, a similar view, showing the draw-heads coupled, and the slide suspended beneath the draw-head, where it falls when not in use; Fig. 3, a top or plan view of the draw-heads when coupled 5 Fig. 6, a transverse vertical section with the pin in position for automatic coupling; Fig. 7, the rod and fastening used to operate the couplingpin from the top of the car; and Figs. 4 and 5, detached views.

A represents a draw-head, having a perfora- V tion, a, for the coupling-pin b. `At the upper end of the pin is an eye, c, to receive the hooks c of the lifting-rod d, which is supported in an upright position by brackets attached to the end of the car. By means of this rod the pin can be operated from the top of the car.

e The neck of the pin is perforated at e to receive a pivot, by which the lever B is attached to the pin. The support f projects upward from the draw-head, and has an arm, f', that serves as a fulcrum for the lever B. The lever is held to the fulcrum by a guard, which permits the Vlever to have a sliding motion as the pin rises or falls vertically. By means of this lever the pin can be operated from between the cars.

.C is a slide to support the pin when drawn up for the admission of the coupling-link D. The slide is connected, by a plate, g, to a block, g', in the draw-head. When the link strikes the block the slide is carried back from under the pin, which drops intoposition and fastens the link. On the under side of the slide is a proj ection, h, and in a recess .in the top of the drawhead is a spring, h. Over ,the recess and spring is placed a plate, a', having a perforation for the pin. As the slide is forced back the spring is compressed by means of the projection, and when the pressure is removed from the block the elasticity of the spring forces the slide against the pin. The pin is set for the admission of the link by being drawn up by the rod d or the lever b until the slide enters a groove, b, in the pin and holds it in position, preventing its being drawn entirely out of the drawhead or falling until the link has entered and pressed the block. A represents another drawhead perforated to receive a coupling-pin. The sides of the draw-head are grooved near the front, as at z', to receive the slide E. The slide crosses the front of the draw-head, and is designed to hold the link in position for coupling when the draw-heads are at different heights. The slots k in the slide are for the admission of projections lc on the sides of the draw-head.

The slots and projections are designed to support the slide when not in use under the drawhead out of the way. F is a lever pivoted at the lower end to the draw-head, and having teeth l and l. The slide is held in position by the teeth Z and the lever, and the lever is held in position by the teeth l and the teeth m on the lever mf, which is pivoted on the top of the draw-head and pressed against the lever F by spring n.. As the draw-heads approach each other and the coupling is effected, the projecting arm G, fastened to the projection j' on the opposite draw-head, strikes the lever F, throwing it back and disengagin g the slide E, which drops and becomes suspended under the drawhead. In the back part of the draw-head a rubber cushion is placed to reduce the concusA hooks c', with the pin b, having the eye c and slots 7c, leverF7 having teethl l', lever m', havthe groove b', plate a, slide G, having downing` teeth m, spring n, and draw-head A', havward projection h., spring h', plate g, block g', and draw-head A, having recess d', substantially as and for the purpose set forth.

2. The combination of lever B,having fulcrumf on projection f, pin b, having pivot-hole e and the groove b', plate a', slide C, having downward projection h, spring hf, plate g, block g', and draw-head A, having .recess d', substantially as andior the purpose set forth.

3. The combination of the slide E, having ing grooves i, and arm G on the draw-head A7 substantially as and for the purpose set forth.

4. The combination of the draw-head A A',

slide E, and link D, substantially as and for the purpose set forth.
