CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 454,045, dated June 16, 1891.

Application filedIebrnary 26, 1891. erial No. 382,917. (No model.)

To all whom it may concern:

Be it known that I, DORA HIRSH, a citizen of the United States, residing in Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Oar-Couplings, ofwhich the following is a specification.

This invention relates to improvements in automatic car-couplers; and the invention consists in the construction and combination of the several parts, as hereinafter fully described, and specifically pointed out inthe claims.

In the accompanying drawings, which form a part of this specification, Figure l is a side View of one of my couplers, shown detached from the car and having both the draw-bars engaged therewith, and Fig. 2 a vertical longitudinal section of the same. Fig. 3 is a vertical longitudinal section of a modified form of the coupler. Fig. 4 is a top or plan view of the ends of two cars connected by the coupler. Fig. 5 is an enlarged view of the lever for uncoupling the cars. Fig. 6 is an end View of the draw-head shown in Figs. 1, 2, and 4, the draw-head being connected therewith; and Fig. 7, an end view of the modified form of draw-head shown in Fig. 3, the draw-bar being detached.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A A indicate hollow draw-heads, which may be either circular or rectangular in cross-section, as shown, respectively, in Figs. 0 and '7.

The draw-heads illustrated in the drawings are divided internally into two sections by transverse partitions a and have openings a in their ends. The partitions prevent the draw-bars from being driven too far into the head, and at the same time form a bearing for the draw-bar in backing the train.

The cylindrical draw-head A (shown in Figs. 1 and 2) has a longitudinal slot to cut in the top of both sections thereof, the metal closing the outer ends of which forms a bearing g, that is engaged by the drawbar, as will be explained. The bearing g is carried down somewhat, so that it closes the upper part of the end of the cylinder, thus increasing the bearing-surface.

In Fig. 3 is shown a modification in the construction of the draw-head, in which the slot is omitted and the bearing formed by a lip h covering the upper part of the end opening a 5 5 The slot may also be omitted in the cylindrical form of the draw-head, or the rectangular form may be made with the slot, as is most desirable.

B indicates draw-bars constructed of spring metal, the outer ends I) of which are bent back over the main portions and constitute spring. bars, which make vertical angles therewith. The vibrating ends of the spring-bars are bent downward and then again upward, so as to form shoulders I), which engage the bearings g or it and loops 12 that embrace said bearings, as seen in Figs. 2 and 8. lVith the slotted draw-heads th e shoulders of the springbars pass upward through the slots to, but in the modified construction they rest against the tops of the draw-heads. The outer arms of the loops 17 extend upward outside of and above the ends of the draw-heads and have bosses 1) formed thereon, that serve as a rest for the heads d of the operating-levers D. These heads engage the reduced ends of the said arms of the loops, being retained thereon by nuts and have jaws (Z formed on their ends, between which the levers are pivoted, as shown in Figs. 5 and 6. Upon the lever D there is constructed a lug d, provided with an elongated slot (1 Fig. 6, through which a fulcrum-pin E, fixed in the platform of the car, passes, the lever being held thereon by the enlarged head 6.

In Fig. 4- is shown two cars G connected by a cylindrical draw-head constructed as just described. This draw-head is detachable from the draw-bars B of one or both cars; but, if preferable, the d raw-head may be permanently secured to one of the cars in the same manner as with any other coupler, and have only one end constructed to be detachably engaged .by a draw-bar.

To couple the cars, the draw-head being connected with. one, the draw-bar to be e11- gaged therewith is guided by its lever D, having the end elevated or depressed by the vertical movement of said lever and a horizontal movement communicated thereto by a longitudinal movement of the lever on the fulcrum-pin E.

To uncouple the draw-bar, the end thereof is depressed, as shown by the broken lines F, Fig. 3, by a vertical movement of the lever D, (shown by dotted lines f, Fig. 6,) so as to disengage the shoulder b from the bearings g or h.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a car-coupler, the combination, with a hollow draw-head having an opening in the end, of a bearing formed in said open end, a draw-bar, and a spring-actuated shoulder connected with the draw-bar and adapted to engage the bearing of the draw-head, substantially as and for the purpose specified.

2. In a car-coupler, the combination, with a hollow draw-head open at the end and having a slot cut through the wall thereof, of a drawbar and a spring-actuated shoulder connected with the draw-bar and adapted to engage the slot in the draw-head, substantially as and for the purpose specified.

3. In a car-coupler, the combination, with a hollow draw-head having an opening in the end, of a bearing formed at said opening, a draw-bar having the end bent back over the body thereof and forming a spring-bar, and a shoulder formed 011 the spring-bar adapted to engage the bearing of the draw-head, substantially as and for the purpose specified.

4. In a car-coupler, the combination, with a hollow draw-head having an opening in the end, of a bearing formed at said opening, a draw-bar, a spring-actuated bar connected With the draw-bar and having a shoulder and loop, and a lever connected with the outer arm of said loop, substantially as and for the purpose specified.

5. In a cancoupler, the combination, with a hollow draw-head having an opening in the end, of a bearing formed at said opening, a draw-bar, a spring-actuated bar connected with the draw-bar and having a shoulder and loop, and a lever connected with the outer arm of said loop and having an elongated slot, and a pin secured to the car and engaging the elongated slot of the lever, all constructed and operating substantially as and for the purpose specified.
