CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 618,886, dated February '7, 1899.

Application filed April 7, 1898. Serial No. 676,760- N modem To all whom it may concern.-

Be it known that I, PATRICK JOSEPH LEE, a citizen of the United States, residing at Velasco, in the county of Brazoria and State of Texas, have invented certain new and useful Improvements in Oar-Couplings, of whichthe following is a full and complete specification, such as will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to automatic carcouplings; and it has for its object to provide a simple and improved coupling device of this character which will eifectively operate to automatically couple, which can be used in connection with the ordinary pin-and-link coupling, and which is adapted to be uncoupled from the sides or top of the car.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same letters of reference in each of the views, and in which Figure 1 is a side view, partly in section, of a car-couplin g mechanism embodying my improvements and showing two opposite drawheads in coupled position. Fig. 2 is a side View of one of the draw-heads with the mech- Fig. 3 is a vertical longitudinal sectional view of the drawhead, showing the mechanism 'in uncoupled position. Fig. 4 is a top or plan View of the draw-head with the latch removed, and Fig. 5 is a horizontal sectional view illustrating the bottom plan of the draw-head.

Referring to the drawings, A designates the draw-head, which is provided with the usual link-recess at, having the flaring mouth a. The draw-head permanently carries a link B, having a pointed or wedge-shaped outer end I), said link being retained in connection with the draw-head and also normally maintained in horizontal position by means of a weighted pin 0, arranged at the rear of the recess C6 and embodying a weighted head 0, passing through a corresponding opening din the top of the draw-head, and a lower end 0, passing through a corresponding opening d in the bottom of the draw-head. The head 0 forms a shoulder 0 which bears upon the rear end of the link 13, and the lower end portion 0 of the pin passes through the link, as shown. The head 0 of this weighted pin and the open ing 61 are preferably of corresponding angular contour in cross-section, so that turning of said pin in its vertical sliding movement is obviated.

E designates the coupling pin, which is adapted to operate in a. corresponding vertical opening f in the front portion of the drawhead and is pivotally connected, as at e, with a swinging bracket or arm G, by which said pin is carried. Said bracket G carries a crosspiece 9 at a point in rear of the pin E, and the bracket is preferably of approximately A shape, with its front ends embracing and pivotally connected to the top of the couplingpin, while its rearwardly-divergent arms g g are pivotally connected at their rear ends, as at g to the top of the draw-head.

H designates a gravity-latch which is arranged in front of the cross-piece g of the swinging bracket G and has a pointed or beveled lower end it, projecting through an openingi in the top of the draw-head and in rear of the coupling-pin openingf. The lower end of this latch and the openingc'are preferably of angular contour in cross-section, whereby turning of the latch in its vertical operation is prevented. This latch is adapted to form a support by which the swinging bracket or arm G is retained in elevated position and r the coupling-pin E is lifted upto the position shown in Fig. 3 of the drawings and ready for the automatic coupling operation. The latch has a trip engagement with the bracket G and is fulcrumed and sustained with its pointed end h projecting a proper distance within the draw-head recess a by means of a cross-pin h, which normally rests upon the top of the draw-head. At the top end of the latch is provided a counterbalance-head 712, and in its rear edge, beneath said counter balance-head, is provided a notch or recess h adapted to receive the cross-piece g of the swinging bracket-arm and forming a shoul der k u on which said crossiece rests.-

The rear edge of the latch, between the shoulder 7L and its pointed end portion 7;, is preferably inwardly curved or inclined, as at 715, so that it forms a way down which the crosspiece 9 will travel when the latch is tripped or released and the bracket or arm G drops downwardly. The link B is provided with a cross-piece I), having a downwardly and rearward] y beveled rear edge N, which is adapted to engage the pointed end h of the latch and operate to lift the latter and disengage it from the cross-piece g of the swinging arm when said link in elevated within the drawhead.

It will be understood that in operation when the swinging bracket G is lifted to its elevated or raised position its cross-piece 9 will travel upwardly against the guide edge or way 7L5 of the latch H until it reaches the shoulder 71/, when the top end of the latch will drop rearwardly by reasonof its counterbalance weighted head If and the cross-piece g will be received within the recess h and rest upon the shoulder If. The coupling-pin E will thus be retained in elevated position with its lower end projecting within the top portion of the vertical opening f, and the latch will operate to sustain the parts in the position just stated. The link B is then in normal horizontal position, and is thus maintained by operation of its Weighted governing-pin C. Now with the parts in this position the automatic coupling is effected in the following manner: WVhen the point of the link of the adjoining draw-head enters the recess a of the opposite draw-head, it will ride up over the link contained therein and operate by engagement with the pointed end It to lift the latch H, or said link will ride under the link contained in the opposite drawhead and operate to lift said link, so that the inclined edge b of its cross-bar b will operate to lift the latch. When the latch is thus lifted by the entrance of the link of an adjoining draw-head, the shoulder 77, will be disengaged from the cross-piece g of the swinging arm G, and as soon as the latch is thus tripped and the swinging arm released the latter will automatically drop downwardly and carry in its movement the coupling-pin E, which will pass through the two links and effect the coupling. To uncouple, it is only necessary to lift the swinging arm to the position first above described until the same is again engaged by the latch, so that it is sustained in elevated position.

To enable the convenient and safe uncoupling of the mechanism, a rod J is pivotally mounted upon the end of the car and comprises opposite end portions j, extending across the ends of the car and to the respective sides of the same, and a forwardly-projecting arm or projection j, the outer end of which is connected, preferably by a chain it, with the outer end of the swinging bracket G. The top arm j may be A-shaped, if desired. A convenient means for operating the mechanism from the top of the car may be provided by a vertical sliding rod L, mounted at the end of the car and connected by a chain on with the outer end of the front arm j of the rod J.

The operation and advantages of my invention will be readily understood. In construction-it is simple and durable, and it will effectively operate under various conditions and circumstances. It will be obvious that it maybe conveniently used for coupling with an ordinary pin-and-link coupling without changing the links, and it will also be noted that the links when coupled will adjust themselves at any requisite angle within the drawhead by reason of the sliding movement of the governing gravity-pin O.

The general construction and arrangement as embodied in my invention provides a double-link coupling, which insures additional strength and security against accident. Each draw-head carries a link and two pins, one being the coupling-pin and the other pin governing the position of the link, in combination with a lifting mechanism for operating the coupling-pin and a latch mechanism operated by the link and governing the opera tion of the lifting mechanism.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
