CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 487,662, dated December 6, 1892. Application filed February 15, 1892- Serial No. 421 6419- (No model.)

.To'all whom, it may concern.-

Be it known that I, HENRY DEITZ, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Oar-Couplers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in car-couplings; and the object of the invention is to provide a coupler of simple and economical construction, reliable, durable, efficient, and automatic in use.

To these ends the invention consists of the features, arrangements, and combinations hereinafter described and claimed.

The invention will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a vertical longitudinal section taken through the center of two adjacent draw-heads, the coupling device on the right being in the locked position, while that on the left is in the unlocked position. Fig. 2 is a top or plan view of two adjacent draw-heads. Fig. 3 is a top view of the coupling device.

Similar reference characters indicating corresponding parts or elements in the several views, let the numeral 5 designate the drawhead provided with the link-recess 6, the vertical opening 7 for the ordinary coupling-pin, the Vertical slot 8, leading backward from opening 7 and extending downward to the central longitudinal opening 9, and the recess 10, leading downward from opening 9 and forming a socket in the bottom of the draw-head and in the rear of the link-recess for the reception of the spherical or ball extremity 12 of the coupling device 14, provided with the hooked forward extremity 15 and the enlarged top 16. (Shown cylindrical in the drawings.)

, The entire body portion of the coupling device, including the hook and excepting the extremities 12 and 16, is of the same width and adapted to enter the vertical slot 8 of the draw-head, while the spherical or ball extremity 12 is adapted to enter the vertical opening 7. Hence the draw-head being cast integral the locking device is placed in position by inserting the ball 12 in the top of opening 7 and moving the same downward to the longitudinal opening 9. It is then moved backward in this opening sufficiently to allow the hook 15 to enter the openingin the top of the draw-head, when the ball is moved downward into its socket 10, the device 14 being thenin either of the positions shown in Fig. 1; but if left to itself it will fall by gravity to the looking position or that shown at the right in this figure.

The outer face of the hook 15 is curved, be ing so fashioned as to cause the device to rise when the link extremity engages the same. As soon, however, as the extremity of the link passes to the rear of the hook the locking device falls to the couplingposition unless supported.

The top or weighted extremity of the locking device is provided with an aperture 18 for the attachment of any suitable unlocking mechanism, which may be of ordinary construction and adapted to temporarily support the locking device in the unlocked position whenever for any reason this may be desired.

It will be observed that in the construction of my improved coupler care has been taken to leave su'fficient room forward of the guard 20, which engages the dead-wood for the operation of the locking device.

It will be observed that when the device is in the locking position its front portion engages the draw-head both at the top and bottom, while the curved face of the hook 15, forward of the vertical front wall of the opening 7, makes it impossible for the device to become unlocked, except by the backward movement of its weighted or upper extremity.

The socket 10 is provided with an opening 10, leading downward therefrom through the bottom of the draw-head, permitting the escape of water, sand, dirt, &c., that might otherwise accumulate within the hollow drawhead.

Having thus described my invention, what I claim is 1. In a car-coupler, the combination of the the same below and in the rear of the link-' recess, and the coupling device provided with the spherical or ball-shaped lower extremity adapted to enter said socket, and the curvefaced hook in front, substantially as described.

2. In acar-coupling, the combination of the draw head provided with an independent socket formed in the rear of the link-recess and the loose hook-shaped coupling device having its lower extremity fashioned to enter said socket, substantially as described.

3. In a car-coupler, the combination of the drawhead having an independent socket formed in the rear of the link-recess and the loose locking device having its lower extremity fashioned to engage this socket, its forward portion being formed into a hook fashioned to cause the device to rise when engaged by the link of the oppositedraw-head, the upper extremity being fashioned to cause the device to fall by gravity to the locking position, substantially as described.

4. In a car-coupling, the combination of the draw-head provided with the pin-hole in front, the slot extending backward therefrom on the top of the draw-head, the longitudinal opening 9, and the socket formed in its bottom in the rear of the link-recess, and the locking device having its lower extremity fashioned to engage said socket, its forward portion hook-shaped and its upper extremity so fashioned as to cause the device to fall by gravity to the locking position, substantially as de scribed.

5. The combination of the draw-head having an independent socket formed below and in the rear of the link-recess and the loose locking device consisting of a body portion having its lower extremity engaging said socket, a weighted upper extremity and a curve-faced front portion formingahook and bearing against the draw-head both at the top and bottom, substantially as described.

6. A draw-head provided with an independent socket formed in the rear of and below the link-recess for the reception of the pivoted lower extremity of the locking-device, the loose locking device, and an openingleading from the socket through the bottom ofthe draw-head for the escape of water, sand, &c., that might otherwise accumulate in the hollow draw-head, substantially as described.

7. In a car-coupling, the combination of the draw-head provided with the link-recess-and a socket independent thereof, and the loose coupling device having its lower extremity fashioned to enter said socket, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

HENRY DEITZ.
