CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 488,857, dated December 27, 1892.

Application tiled October 8, 1892. Serial No. 448,256. (No model.)

To all whom it may concern.-

Be it known that I, AUGUST G. VOGT, residing at Boerne, in the county of Kendall and State of Texas, have invented a new and useful Improvement in Oar-Couplings, of which the following is a specification.

Thisinvention is an improved car coupling seeking among other improvements to provide simple, easily operated devices by which the cars may automatically' couple, and be uncoupled, or the link be adjusted to properly enter a meeting drawhead Without requiring the operator to go between the cars at any time and the invention consists in the novel constructions and combinations of parts hereinafter described and pointed out in the claims.

In the drawings-Figure 1 is a perspective view,Fig. 2 a top plan View, parts being broken away, and Fig. 3 is a side view part in section of my improvements, and Figs. 4, 5 and 6 are detail views.

The drawhead A has its drawbar B made hollow and open at its rear end so the buffer spring C employed on the ordinary drawbars may be inserted in said rear end and held between the keys D D passed through slots b in the drawhead and into receiving slots in the draft beams of the car frame. This construction it willbe seen is simple, permits the use of the springs O and keys D D now used and allows the drawhead to yield both forward and back. If at any time the spring should be broken the rear key can be removed anew spring inserted and the key be replaced in a few minutes.

The drawhead has the Haring link mortise in which the link holder operates. This link holder is formed of two sections E E arranged one below the `other and slightly separated.

Near their rear ends the said sections are piv-l oted at e to the drawhead and a spring E2 bearing between the rear extension e2 of said sections operates to adjust said sections normally toward each other at their front ends. Near their forward ends the sections E E have vertical coincident openings E for the coupling pin.

An adjusting frame F is fitted over the sections E E and is arranged to slide vertically in the drawhead. This frame F operates to depress the lower and upper sections E E', the frame having two such end shoulders or surfaces f f to rest above and below the lower section E', the former f also resting under the upper section so that the raising of the frame will lift both sections positively while the lowering of the frame will only depress the lower section positively the upper section ordinarily following by gravity and the section of the spring. It will be seen that the sections have a certain independence of movement this being desirable because when adjusted to hold thelink they may be set up and down together while when set to receive an entering link it is desirable that they should be dared apart at their front ends. In securing this last adjustment the lower section E may be depressed by the frame F,'while the upper section E may be raised by the means presently described. At its lower end the frame F has a rod F extending below the drawhead and through a bracket F2 and receiving actuating springs FE'F4 above and'below said bracket. At its upper end the frame has an extension F5 slotted at f5'for the passage of the operating lever G, which for convenience of reference I shall term the main lever to distinguish it from the lever H which may be termed the pin lifting lever. The main lever thus operates to adj ust the link lifting jaws. This lever Gis supported so it can rock and also move longitudinally being to such end pivoted on a bolt or stud I passed through alongitudinal slot i in the lever. I also form the main lever at g with a lateral offsetbywhich it may when moved longitudinally be set into and out of positiop to engage the lateral offset h on the pin lifting lever. The lever H is pivotedy at J and is connected with the upper link adjusting section E by a rod K pivoted to said section and passed upward through an opening in a joint block K connected with the lever H and having above such joint piece a nut or other head la for engagement by the leverH when the IOO pivoted at its upper end to the lever and pivotally connected at its opposite end with the lower end of the rod M which has at its upper end a transverse arm connected with the coupling pin so that the movement of thelever may operate to raise and lower the pin. The arrangement of rods L and M is desirable because it enables the pin to be moved to the full extent of the swing of the lever and at the same time permits the pivoting of the lever to the drawhead. A rod N may connect with the lever H and extend to the top of the car to enable the uncoupling of the cars from such point.

A latch O is pivoted at 0 to the drawhead to swing in the direction of length thereof. This latch has a weight O at its lower end and a hook or shoulder O2 at its upper end and such hook or shoulder is arranged to engage the main lever G when the latter is adjusted longitudinally and moved to swing the pin to uncoupled position so that the hook may hold the main lever in position to secure the pin in uncoupled position. When the drawheads meet the jar of the impact swings the latch and releases the lever G which permits the pin to fall and automatically couplethe cars. To permit the said hook to catch, a part of the lever is cut out or notched at P forming a seat for the hook but the said lever is made so wide at other points that the hook cannot engage it thus avoiding the latching of the lever when it is used simply for adjusting the link.

A casing Q is provided upon the drawhead for in closing some of the operating parts, such casing having a hinged lid q which may be raised and lowered with the movements of the pin dac.

In operation if the link be in place the main lever may be adjusted clear of engagement with the lever I'I and then be operated to raise or lower the link to enter a meeting drawhead. If the approaching drawhead also has a link in it, the link in the rst can be readily ejected by setting the main lever to engage the lever G and then operating the same to raise the coupling pin and spread the link lifter sections when the link will drop out and the parts be left in position to receive the approaching link. When so adjusted the main lever will be held by the swinginglatch until the drawheads meet when the jar will release the latch and the levers and pin will adjust to coupled position. 'When the link is ejected as before described it does not drop to the ground but lis caught by a link receiving hook R supported to swing below the drawhead and projecting at its point beyond the same. This hook R is carried by swinging links S dropped from the drawhead. It will be seen that the pin is braced against both the drawhead and the sections of the holder so that there is no danger of bending even a lighter pin than is commonly used.

In order that the link catcher may not be in the way when the cars are coupled I proof the hook back from the end of the draw-` head or the latter may be released to permit the hook to adjust forward into position to catch the link.

Having thus described my invention, what I claim is l. In a car coupling, the combination of the drawhead and the sectional link holder therein, both the drawhead and the link holder having openings for the coupling pin, and the openings in the link holder being closed at the front, substantially as set forth.

In a car coupling, the combination of the drawhead having coupling pin openings, the link holder arranged in said drawhead and formed with upper and lower sections pivoted together near their rear ends to the drawhead and provided near their front ends with pin openings closed at their front sides and the spring arranged between the rear extended ends of said sections, substantially as set forth.
