CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 422,532, dated March 4, 1890.

' Application filed December 19, 1889. Serial Ne. 334,341. (No model.)

To all whom. it may concern..-

Be it known that I, ABRAHAM KIMBER, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Oar-Couplings, of which the following is a specification.

My invention relates to an improvement in that class of car-couplings in which an ordinary coupling-link is used in connection with a swinging automatic stop or coupling-pin.

The objects of my improvement are, first, to provide improved means for handling the link and the coupling-pin, whereby either the free end of the link may be raised orlowered or thecoupling-pin may be raised by means of the same lever,-at' the will of the operator; and, second, to provide improved means for limiting the outward movement of the coupling-pin, all as hereinafter fully explained.

The accompanying drawings illustrate my invention.

Figure 1 represents a longitudinal vertical section; Fig. 2, a front elevation; Fig. 3, a side elevation; Fig. 4, an elevation showing the opposite sides, and Fig. 5 a plan. Fig. 6 is a view in perspective of the coupling-pin.

A is the draw-bar, having in the under side of the throat a central rib B, adapted to pass between the sides of the ordinary couplinglink 0, and having on its upper side and outer end an upwardly-projecting lip d.

F is a shaft arranged across the throat of the draw-bar at its entrance and flush with its floor. Shaft F is provided with a pair of flat arms 71 h, which extend backward from the shaft along the floor of the draw-bar on each side of the rib B. One end of the shaft F projects through one side of the draw-bar and is provided with a crank 'L, Fig. 3.

J is the coupling-pin,which is substantially rectangular in section at its upper end, and is provided on two opposite sides w th projecting shoulders 7c 70. Coupling-pm J 1s mounted in a mortise Z in the upper side of the draw-bar and projects downward across the throat, the shoulders k is resting in corresponding recesses m m in opposite sides of the mortise. Pin .I is pivoted at its upper forward cornerto the draw-bar by means of a shaft N, which rests in bearings in the sides of the draw-bar, and projects through on one side and terminates in a crank 0, Fig. 4., the arrangement being such that the shaft passes through the coupling-pin and the pin turns with the shaft.

Mounted on the front end P of the car, above the draw-bar, is a hollow shaft R,having an arm S, which is sustained in a substantially horizontal position by a cord or chaint, which is attached at its upper end to the car. Arm Sis connected with crank O by a short chain a, the arrangement being such that when arm S is turned upward by the rotation of the hollow shaft R the coupling-pin is swung upward and backward out of the throat of the drawbar. Passing through shaft B, so as to turn easily therein, is a shaft T, having an arm V secured there'- on. Both ends of shaft T are bent downward to form cranks WV and X, and the arrangement of arm V and crank WV is such that the shaft is free to move longitudinally in shaft B, said movement being limited by the contact of arm V and crank W, respectively, with the ends of the hollow shaft. Arm V is connected at its free end with crankvlof shaft F by a chain y, the arrangement being such thatthe chain hangs slack, as shown in Fig. 3, so that crank t' is not affected by the upward movement of the arm until the arm has moved through nearly a quarter-circle. That end of hollow shaft R which is next to crank W is cut away, so as to leave on one side a projecting point 2', adapted to engage one side of crank W.

In operation, the parts being in their normal position, arms h of shaft F lying along the interior bottom of the draw-bar, and the coupling-pin standing vertically across the throat, its free end engaging the lip 01 of rib B, one end of link 0 is introduced into the throat, the free end of the pin is pushed backward by the end of the link, and then drops back to its normal position and within the link. On pulling link 0 outward it is held by the pin, and the pin'is prevented from swinging outward both by its engagement with the lip d of rib B and by the engagement of the shouldersk k on the pin with the bottoms of recesses m m in the draw-bar. The outeror free end of the link is normally depressed when not coupled with another draw-bar, and is raised, as indicated in dotted lines in Fig.

1, by the operator sliding shaft '1 lengthwise in shaft R until crank V therein is clear of engagement with the projection 2 on shaft R, and then turning shaft T in shaft R, thus raising the free end of arm V, thus turning shaft F outward and raising arms 7b 7b thereon, on which arms the link rests in such a manner that its outer end is tilted upward. For the purpose of swinging the couplin g-pin backward, and thus releasing the link, shaft '1 is slid lengthwise in shaftR until crank WV on shaft '1 engages the point z on shaft R. Then by the turning of shaft R shaft T is also turned and its arm S is raised, thus by means of chain a and crank O turning shaft N and swinging the coupling-pin backward and upward out of the path of the link. The coupling-pin may be secured in its raised position, so as .to avoid catching the link, by securing the end of cord to a stud p, projecting from the car-body.

I claim as my invention- 1. In a ear-coupling, the combination, with the draw-bar, the shaft F, having arms h h and crank 1 the shaft N, having pin J mounted thereon so as to turn therewith, and crank O, of the hollow shaft R, having arm S, shaft'l, mounted in shaft R, adapted to slide longitudinally and to turn therein, and having arm V and cranks V. and X, means for detachably connecting shafts R and '1, so as to turn in unison or separately, and chains 1 and 10, whereby the couplingdink is tilted by means of shaft R when disconnected from shaft '1, and the coupling-link is released when shafts R and T are connected, as set forth.

2. In a car-coupling, the combination of the draw-bar, having mortise Z and recesses m m, and the coupling-pin J, pivoted to the drawbar, as shown and described, and provided with shoulders 75 is, arranged to engage the bottoms of recesses 1n, as and for the purpose specified.

3. In a car-coupling, the combination, with the draw-bar having rib Bend the coupling link 0, of the shaft F, arranged across the front lower edge of the throat of the draw-bar and having arms h h extending within the throat beneath the link, and the crank 1', whereby the coupling-link maybe tilted, as and for the purpose set forth.
