CHARLES LEISOHER, OF EASl PIERRE, SOUTH DAKOTA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 488,078, dated December 13, 1892.

Application filed August 2 1892.

To all whom it may concern:

Be it known that 1, CHARLES LEISCHER, a citizen of the United States, residing at East Pierre, in the county of Hughes and State of South Dakota, have invented certain new and useful Improvements in Car-Couplers; and I do hereby 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.

This invention relates to car-couplings and its object is to make the same auto maticthat is-to say, to produce the coupling by the simple introduction of the link, extending out from one of the draw-heads on one car into the other car when the cars are pushed together. It has for its object, moreover, to so construct the parts that the rain and water will be shed off from the interior of the drawheads, and thus protect the interior mechanism of the coupler against corrosion and other injurious actions.

For this purpose my invention consists in the features and combination of parts hereinafter set forth and covered in the claims.

In the drawings accompanying this specification, Figure 1 represents a vertical longitudinal central section of a coupler embodying my invention. Fig. 2 represents a perspective view of one of the draw-bars; and Fig. 3 a transverse vertical section on line 3 3, Fig. 1.

By referring to the drawings it Will be noted that the draw-bars A A, which are of any ordinary or suitable construction and which may be attached to the cars in the usual way, are provided with the usual draw-heads having abell-shaped mouth A, and are, moreover, formed with the vertical transverse slotsa a in the top and bottom of the draw-bars, respectively. Each draw-bar is provided at its top with a yoke B, pivoted at its rear at b, and having a rearward extension 12', whereby its yoke is adapted to swing upwardly in a vertical plane, the upward motion being limited by the rear extension I). A coupling-pin O is pivoted to and depends from the front end Serial No. 441,990. (No model.)

of each yoke B at its under side and is provided with a lug 0, extending forwardly and limiting the motion of the pin in a forward direction by bearing against the'under side of yoke B. This coupling-pin (J in the normal position of the parts extends downwardly through both slots at and a, as shown at the left side of Fig. 1, and thus serves to lock the coupling-link D in position. The upper surface of each draw-bar is provided with two retaining-ribs 01. 0. with which two corresponding longitudinal grooves b b on the under side of the yoke B are adapted to engage, as best shown in Fig. 3, and thereby prevent anylateral play of the yoke, whereby damage to the mechanism may result.

The yoke B extends entirelyover the upper side of the forward part of the draw-bar A, and is preferably beveled off at the sides and front, as shown at b so as to shed the water and prevent its access to the interior of the draw-bar and consequent damage to the operating parts.

A chain E may be attached to the upper faces of the yokes to raise the same for uncoupling, and these chains may be carried to any convenient part of the car where it can be handled by the brakeman conveniently and without danger or risk to himself.

The operation of this coupler is apparent from the foregoing. When a car is pushed toward another, the link D from one drawhead enters the mouth of the other drawheadand pushes the coupling-pin 0 rearwardly until it passes the same, when the said coupling-pin will drop back into the vertical position and lock the link, thusefiecting the coupling. When it is desired to uncouple the car, the yoke Bis simply raised by the chain E, or otherwise, thus permitting the link D to be withdrawn.

What I claim, and desire to secure by Letters Patent, is

1. In a car-coupler, the combination of a draw-head having longitudinal slots in top and bottom with a yoke pivoted to the top of. the draw-head and a coupling-pin depending from the under side thereof and provided with an upper forward lug, as 0, adapted to draw-head, and a coupling-pin depending bear against the under side of the yoke to from the yoke, substantially as set'forth. IO limit its motion, substantially as set forth. In testimony whereof I aflix mysignature in 2. In a ear-coupler, the combination of a presence of two Witnesses. 5 draw-head having vertical slots and 1ongi-' CHARLES LEISOI-IER.
