CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 506,314, dated October 10, 1893.

Application filed February 23, 1893. Serial No. 463,434- (No model.)

To aZZ whom it may concern.-

l 3e it known that I, REUBEN L. GARLIOK, a citizen of the United States, residing at Watertown, in the county of Oodington and State of South Dakota, 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.

My Invention relates to improvements in car couplers,-and it has for its general object to provide a coupler embodying a head adapted tosupport the coupling pin in an elevated posltion, and mechanism for automatically releasing the pin when the cars come together,

so that said pin will take down through thelink and effect a coupling.

A further object of the invention is to provide a device through the medium of which a person standing at the side of the car may ralse the pin, and means for locking said dev ce m such a position that it will hold the pln 1n an elevated position and prevent a coupling when the cars come together, and: a st1 ll further object of the invention is to provide a draw bar and .a stirrup for connecting said bar to a car, so constructed thatwhile the-bar may be moved vertically and laterally, it will be caused to resume its normal, central position when released.

Other objects and advantages of the inventlon will be understood from the follow- 1ng descriptionand claims when taken in connection with the annexed drawings, in

which- Flgure 1, is a view illustrating my improved coupler in position upon a car; the draw head and a portion of the draw bar being illustrated in section. Fig. 2, is a perspective View of the weight for inclining the link.

Fig. 3,is a detail, side elevation of the bracket for locking the pin-raisin g device or rock shaft so that it will hold the pin in its elevated'posltion; and: Fig. 4., is a section taken transversely through the draw bar and one of the stirrups, and: Figs. 5, and 6, are similar views of modifications.

Referring by letter to said drawings and more particularly to Figs. 1, to 4, inclusive: A, indicates a car which may be of any approved construction. 1 Y

a pin aperture 0; and it has the bottom wall (1, of its throat inclined forwardly and upwardly, as illustrated, for a purpose presently to be described. Seated and adapted to move vertically in an opening formed in the upper wall of the draw head B,is the reduced shank e, of a weight D, which has its lower end beveledas shown, and is designed and adapted to bear upon the link f, so as to elevate the forward end of the same and enable it to take into a draw head higher than the one in which it is secured. This weight D, is provided in its shank with a transversely disposed slot g, and it is connected to the draw head by a transverse bolt h, which takes through the slot g, as shown.

E indicates an enlargement which is suitably connected to or formed integral with the upper side of the draw head B, in advance of the pin opening a. This enlargement E, is designed to protect the weight D, from damage when the cars come together, and it is provided in its rear side with a vertical recess '5, which aligns with the pin opening 0, and is designed to serve in conjunction with a similar recess j, in the weight D, to form a passage for the coupling pin F. The recess j, of the weight D, communicates with agroove 10, as better shown in Fig. 1, and this groove is, which has its rear wall inclined upwardly and rearwardly, as illustrated, communicates in turn with a countersunk seat or opening Z, formed in the upper side of the weightD. By this construction it will be readily perceived that when the coupling pin F, which has abeveled head m, is pulled upwardly and rearwardly, it will seat itself in the groove 70, and its head will engage the wall of the seat or opening I, and it will be supported in its elevated position, so as to allow a link to enter the draw head.

In order to unseat, and displace the pin F, so that it will take down throughthe link when the cars come together, I provide the slidable bolt G, which takes through a bore 19, formed in the weight D,'as shown. This IOO.'

bolt G, normally bears at its forward end against the pin F, and its rear end extends I, is provided at an intermediate point in its length with a crank branch q, with which the pin F, is connected as shown, so that when the shaft isrocked rearwardly, the pin will be pulled upwardly and rearwardly into its sea In order to enable a trainman standing at the side of a car to prevent the pin F, from falling when the cars come together, I provide the bracket H, with a recess 03; the bottom wall 5, of which serves to form a stop for t the crank branch q. By this construction it will be readily perceived that when the shaft I, is rocked rearwardly so that the branch g,

rests upon the wall 3, the chain i, will meeta j dead center at a, and the pin will be held elevated, but on the other hand, it will be seen i that when the shaft is rocked forwardly so that the branch q, will rest upon the forward end of the wall the pin will be permitted to fall when itis unseated as before described.

As better illustrated in Fig. 4:, of the drawings, the stirrups C which are of a general rectangular form, have the middle portion of their lower bar o, depressed so as to form a seat to, for the reception of the longitudinal projection 4r, upon the under side of the draw bar C. This draw bar 0, is smaller in crosssection than the stirrups O, and is consequently free to move therein; and the projection m, of the said draw bar is of a shape in cross section corresponding to that of the seat to, whereby it will be seen that while the draw bar may be moved vertically or laterally so as to carry its draw head against the draw head of another car, it will be caused, when released, to resume its normal, central position, which is an important desideratum. By reason of the draw bar being permitted to move vertically and laterally as just described, it will be further seen that a great portion of the strain upon the draw bars, incidental to the swaying of the cars, will be removed which is an important advantage.

In Fig. 5, of the drawings I have illustrated a modified form of stirrup C the lower bar 0, of which is of an obtuse form as shown so as to form a seat to, for the lower side of the draw bar 0 This lower side of the bar 0'', is beveled from its edges to its longitudinal center, as illustrated so as to form the projection 00', which is designed to rest in the seat to when the bar is in its normal position.

In Fig. 0, of the drawings I have shown a stirrup G which has its lower bar v rounded or concaved to form a seat 10 This stirrup G, is designed and adapted to be employed .in conjunction with the draw bar G which has a convex projection m upon its lower side as shown,

In all of the constructions illustrated in Figs. 4, to 6, it will be seen that when the draw baris moved out of its normal position, and is released it will return to its normal position and rest upon the middle of the lower bar of the stirrup.

It will be seen from the foregoing description that my improved coupler is very simple, durable and easily operated and that it is well adapted to withstand the shock and jar, which is an important desideratum.

Having described my invention, what I claim is 1. In a car coupler, the combination with a draw head having a pin opening, a recess a groove 70, communicating with the recess 3, and the pin opening and having its rear wall inclined upwardly and rearwardly, and a countersunk seat Z, communicating with the groove 7c; of a coupling pin havinga head at its upper end adapted to rest in the countersunk seat Z, substantially as specified.
