CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 503,855, dated. August 22, 1893.

Application filed February 25, 1893. Serial No. 463,740. (No model.)

To all whom it may concern.-

Be it known that'I, EDWARD B. HYRE, a citizen of the United States, residing at Red Knob, in the county of Roane and State of West Virginia, have invented a new and useful Oar-Coupling, of which the following is a specification.

The invention relates to improvements in car couplings.

The objects of the present invention are to improve the construction of car couplings, to provide a simple and comparatively inexpensive one which will couple automatically with draw-heads at different elevations, and which may be readily uncoupled and set for coupling from either side and top of a car and without going between cars.

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

In the drawings-Figure 1 is a perspective View of a car couplingconstructed inaccordance with this invention. Fig. 2 is an elevation of the draw-head. Fig. 3 is a longitudinal sectional View, showing the position of the parts whenthe pin is set for coupling. Fig. 4 is a similar view showing the coupling pin elevated preparatory to setting for coupling. Fig. 5 is a transverse sectional view. Fig. 6 is a horizontal sectional view on line 6-6 of Fig. 2. Fig. 7 is a detail view of the coupling pin.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a draw-bar havinga draw-head 2 and provided on its upper side or top with a hinged section 3, pivoted at 4 by a transverse pin 5 and provided with a rearwardly extending shank 6, beneath which is arranged a spiral spring 7. The draw-head has laterally extending stop-flanges or shoulders 8, and is provided at the top of the upper sec tion 3 with a horizontal way 9, which receives a pin supporting and carrying slide 10 and which is open at the front to permit the slide 10 to project beyond the draw-head when moved forward. The slide has opposite longitudinal flanges 11 to fit in the grooves of said way 9, and is provided with a vertical cavity 12,

which is open at the bottom and which is adapted to register with a coupling pin perforation 13 of the draw-head to permit a coupling pin 14 to drop to engage a link 15.

In the bottom of the ways 9 is a recess 16 receiving a sliding plate, and having its rear portion enlarged to form stop shoulders 17 to be engaged .by lateral projections 18 of the sliding plate 19 to limit the forward movement of the plate. The plate is adapted to support the coupling pin in an elevated position, and when the coupling pin is raised the plate is moved forward under the coupling pin to cover the perforation, by means of a rock-shaft 20, which is journaled at the back of the slide and is provided witha depending arm 21 to engage a socket opening 22 of the plate, and with a forwardly extending spring arm 23 having its front end bent inward and pointed to engage aboss 24 to hold the plate positively beneath the coupling pin. Theda pending arm is arranged in a tapering slot 25 of the slide; and the resilient or spring arm 23 is loosely connected by a chain 26 with a bar 27, which is connected with the coupling pin. The bar 27 extends upward from the coupling pin to the top of the car, to which the coupling is applied, and terminates in a handle to enable the coupling pin to be lifted from the top of the car; and the coupling pin is lifted from the sides of the car by inclined rods 28 arranged in guides 29 and having attached to their upper ends chains 30, which pass through blocks 31 and are attached to the bar 27 and thereby connected with the coupling pin. The chain 26 has sufficient slack when the coupling pin islowered to permit the coupling pin to be raised above the sliding plate 19 before the rock-shaft is turned to advance the plate to a position beneath the coupling pin.

When it is desired to set acoupling pin for automatic coupling, after it is raised and is supported by the plate 19 as described, the slide 10 is moved forward by a bell-crank lever 32 to carry the coupling pin forward beyond the plate 19, and to cause the slide to project beyond the front of the draw-head, whereby when cars come together forcoupling the slide will be moved inward from its extended position and will carry with it the coupling pin, which is in front of the plate draw-head and adapted to extend across the coupling pin'pert'orati'on when the coupling pin is raised tosupport the latter, and a rockshaft provided with a depending arm to engage and actuate the sliding plate, and having arforwardlyextendingresilient arm provided at its outer endwith an inwardly extending. portion and loosely connected with L thecoupling pin, substantially as and for the ing 35 of the draw-head. The rear end ot the bell-crank lever is connected to a lifting rod 36 whlch extends upwardto the top of-the car and terminates in a handle; and in order to enable the coupling pin to be set for automatic coupling from either side of the. car

1 rods 37v and chains 38 are provided and are extension or vertical arm 42 of the coupling 3 P mounted on the end of the carsimi'lar to the rods and-chains 28 and 30.

' Inorderto enable the coupling pin toyieldf readfl-y'm' itsconnectionwith the verticalbarj 27' to. the. movements of the slide, it has its upper end provided with an inwardly curved arm 39', which isa-rranged' in an opening t'O' of the "bar 27, and'v it is provided with asocket 5 41 to receive thel'ower end of the-bar27'. The

pin proper at the rear. or inner side thereof,

and the curved. arm extends inward from an in.v It will vbe seen that the car coupling is vpositive and reliable in operation that'i'tpwifllf couple automatically and that it may be readily'uncouplfed and set for automatic'coup li-ngfro'm eithersi'de or top ofa car without necessitating going between cars. o

I desire it to. be understood thatchanges the form, proportion and the minor details of; construction may be resorted to without d'eparting from th'eprinciple or. sacrificing any of the advantages of this invention.

The front of the drawhead is provided at I the-bottom. of the link cavity with an inclined I or beveled portion to enable a. link atsdiifer- I out elevations-to readily enter the draw-head.

The particular construction of the drawhead enables. it to yield readily to the link and to-- assist in. springing the link back to a level position when uncoupled from the ad-' jacent-cart What I. claim is- 1 I. In a. car coupling, the combination of-fa drawehead having av coupling pin perforation,
