vCAR-COUPLING.

,SPECIFICATION forming part of Letters Patent No. 746,729, dated December 15, 1903.

Application tiled July 27, 1903. Serial No. 167,152. (No model.) A

vin the county of Licking and State of Ohio,

have invented certain new and useful Improvements in Car-Couplings; and Ido hereby declare the following to be a full, clear,and exy act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved coupling of simpliiied construction of the kind adapted to automatically couple the cars.

The invention consists in the construction hereinafter described and claimed.

In the accompanying drawings, showing an embodiment of the invention, Figure 1 is a horizontal sectional view of the draw-head, exposing in top plan view the operative parts of one coupler in the coupled position. Fig. 2 is a similar view showing the same parts in uncoupled position. Fig. 3 is a similar view showing the same parts in coupled position on a curved track. Fig. 4 is a vertical sectional view showing in full lines the lock down and in broken lines the lock up. Fig. 5 is a front or end view showingthe coupled position oi' the parts. Fig. 6 is a perspective of the lock. Fig. 7 is a perspective view of a lever or kicker for moving the knuckle to open position. Fig. 8is a perspective of the knuckle.

Like characters of reference designate corresponding parts.

The draw-head 1 has an appropriate cavity to receive the inner leg ofthe knuckle 2, the lock 3, and the kicker 4. The draw-head also has a boxed-in cavity or hood la above the main cavity, into which the lock can he lifted and guided. The knuckle 2 has a leg 2?, on the outer side of the end of which are formed lock-engaging shoulders 2b and 2, the shoulder 2c being set back of the shoulder 2" and having adjacent thereto a seat 2d, upon which the lock rests when engaging the said shoulder 2. rear side a toe 2e, adapted to engage a projection 1b in the head of the cavity, as hereinafter described.

The lockl 3 consists of a rectangularly- K shaped block having avertical rib 3a project- The knuckle-leg 2a also has at its ing from its side and at its lower end a stud 3b projecting horizontally from the rib. The lock slides vertically in an opening in the upper wall of the draw-head, the edges 3 and 3d serving to guide and hold the lock from horizontal play. Attached to the upper end of the lock is a rod 3e, passing up through the hood la, by means of which the lock can he lifted.

The kicker or knuckle-opening device 4 consists of a bell-crank lever. ThisV is fulcrumed on a pin 4? in the upper wall of the draw-head in rear of the knuckle and in such position that the lower end of the depending arm 4b' of the lever may strike the legv of the knuckle and .impel it outward to open position. The end of the arm 4J can be made rounded, so asr to properly bear upon the leg. The upper arm 4. of the kicker reaches forward, soas to lie above and in the path of the stud 3b on the lock 3.

The operation is as follows: Assuming the parts to be iu the position indicated in Fig.

l and it is desired to put the parts into position to couple, the lock is lifted until the stud 3b strikes and lifts the upper arm of the kicker. ward, as seen in Fig. 2. In this position the lock will rest on the upper face oi' the end of 'the leg, and iu this position the coupling will be ready to connect with another.. When hit with another approaching coupling, the lock will drop by gravity, rst on the seat 2d and then to the floor of the draw-head cavity. lf the cars come together ona curved track, the lock will stop on the seat 2d and the knuckle will be locked and the cars coupled by the engagement of the. rib 3a and projection 3b with the shoulder 2C. When the cars run onto a straight track, the knuckles are automatically, by the alinement of the cars, turned into position where the lock will drop, so that the rib 8a and projection 3b will engage the shoulder 2b. When the cars come together, in the first instance,'on a straight track, the lock Will not stop on the seat 2d, but pass immediately down to the last-described position. tion shown does not operate the kicker until it is lifted high enough to permit the leg of the knuckle to pass under the lower end of The lock in the construc- This will` throw the knuckle outthe lock. The lower end of the lock when completely down is braced by a projection 1c on the bottom of the coupler-cavity.

What I claim, and desire to secure by Letters Patent, isv l. In a car-coupling, the combination of the knuckle having a leg with a lock-engaging shoulder, a lever having one arm adapted to actuate the leg to throw the knuckle into uncoupled position, a sliding lock having a rib 3LA with a projection 3b at its lower end, said rib and projection 3b to engage the leg of the knuckle, and the projection 3b also to actuate the other arm of the aforesaid lever.

2. In a car-coupling, the combination of the knuckle having a leg with two lock-engaging shoulders, a lever having one arm adapted to actuate the leg to throw the knuckle into uncoupled position, a sliding lock having a rib 3a with a projection 3b at
