Specification of Letters Patent.

Patented Nov. *3, 1916.

Application filed July 12, 1913. Serial No. 778,670.

To all whom it may concern:

Be it known that I, ARTHUR J. BAZELEY, a citizen of the United States, and a resident of Cleveland, Cuyahoga county, Ohio, have invented new and useful Improvements in Car-Couplings, of which the following is a specification, reference being had to the accompanying drawings, in which,

Figure 1 is a sectional plan of my improved coupler with the parts in locked position; Fig. 2 is a section on the lines IIII of Fig. 1 and with the knuckle removed; Fig. 3 is a sectional side elevation showing the parts in locked position; Fig. 4 is a view similar to Fig. 3 but with the parts in lock-set position; Fig. 5 is a sectional plan with the knuckle in open position; Fig. 6 is a sectional side elevation of the parts in the same position as Fig. 5; Fig. 7 is a detail view of the side opening lever; and Fig. 8 is a detail view of a modified form of this lever.

My invention relates to car couplers of the same general typeas that shown in my Letters Patent No. 1,144,316, dated June 22, 1915, and provides novel means for operating couplers of that type.

My invention also relates to the various parts which I shall hereinafter describe and claim.

Referring to the drawings, A indicates a coupler-head, B the knuckle, C the lock, D the knuckle thrower, and E the actuating mechanism. The actuating mechanism is comprised of a lever 2, shaped somewhat like an inverted T, and a connecting rod 3. The arm 4 of the lever 2 terminates at its upper end in an apertured forked-shaped portion 5, by which attachment is made to the uncoupling mechanism. One end 6 of the cross-piece of the lever 2 is pivoted to the coupler-head at 7, and the remainder of the cross-piece of the lever comprises a sleeve 8 for the reception of the connecting rod 3. The connecting rod 3 consists of a straight shaft journaled within the sleeve 8 and an angular upwardly-extending portion 9, the inwardly-turned end 10 of which is adapted to fit within an inclined recess 11, in the bottom of the leg of the lock C. At the end of the connecting rod 3 opposite to the portion 9, is an annular groove 12, which, when the rod has been inserted in position in the sleeve 8, comes opposite a small lug 13 projecting inwardly from the sleeve portion of the member 2. When the rod has been inserted into the sleeve 8 so that the groove 12 and the lug 13 are in alinement a blow is struck at the point a: on the exterior of the sleeve, and the wall at such point is bent inwardly to such an extent that the lug 13 will enter the annular groove 12. The engagement between these parts will hold the rod 3 against movement endwise of the sleeve 8, while permitting it to rotate freely therein.

When the parts are in locked position the arm 1 of the member 2 will lie closely against the outside rear wall of the couplerhead out of the way of injury, as is best shown in Fig. 1. With the parts in locked posltion the upper end of the rod 3 is adapted to underlie a shelf 14 on the couplerhead, and thereby prevent the lock from creeping. Upon the under side of the coupler-head there are transverse walls or flanges 15 and 16, which form a guideway for the lower end of the lever 2 and maintain the lever 2 and the rod 3 in aline ment with the leg of the lock C regardless of looseness at the pivot 7.

The knuckle throwing lever D has a trunnion portion 17 which is ournaled in a hole 18 in the floor of the coupler-head to permit said lever to-rotate in a horizontal plane to actuate the knuckle. The hole 18 is made considerably larger than the trunnion 17, thereby permitting the rear end 19 of the body portion of the knuckle throwing lever and of the trunnion 17 to roll against a vertlcal wall to the rear thereof in the couplerhead as shown in Figs. 1 and 3, thereby eliminating friction and permitting the knuckle thrower to rotate with a free movement.

In Fig. 8 I have shown a modified form of operating mechanism in which the rod 3 is. mounted 1n journals 20 and 21 formed on the cross-piece of the lever 2 When the uncoupling mechanism is actuated, a pull on the arm 4 of the lever 2 to the left as shown 1n F 1g 2 will rotate the lever about its fixed pivot 7, and this rotation will lift vertically the sleeve 8 of the lever, and with it the rod 3, whose curved end 10 which engages the slot 11 in the lock, will rise and at the same time will also rotate in a clockwise d1 I'QCt10Il (as will be seen by reference to Fig. 3). The initial upward movement of the lever 2 will cause the end 10 of the rod.

3 to slide upwardly and rearwardly in the slot 11 in the legof the look. This move ment is limited bythe length of the slot 11, serves to clear the end 10 of the lever from. the lock-to-the-lock position Whichit occupies beneath the shelf 1 and ceases as soon as the end 10 comes into contact with the upper edge of the slot 11. A further rota tive movement of the lever 2, about its pivot 7 will cause the arm 10 to lift the rod, the rod 3 meanwhile rotating farther in its journals in the sleeve 8 and exerting a lifting force on the look, as well as a tendency to move the leg of the lock rearwardly. As the lock rises it will go into loch-set position as shown in Fig. 4, or if the knuckle is unrestrained will cause the knuckle-thrower D to rotate in the manner described in my Letters Patent No. 1,144,316 mentioned above.

It is obvious that various modifications may be made in the device which I have shown and described herein without depart ing from my invention.

What I claim is:

1. In coupler operating mechanism, a le ver pivotally mounted on the coupler head. and arranged to swing transversely thereof, a rod secured to the lever having an actuat ing connection with the lock, said rod being adapted to swing transversely with the lever and having a rotative movement independent thereof about its own longitudinal axis.

2. In coupler operating mechanism, a lever pivotally mounted on the coupler head and a rod forming an actuating connection between the lock and the lever, said rod be ing adapted to be rotated with the lever about the pivot of the lever and being ar ranged longitudinally thereof, said rod having an actuating connection with the lock and being adapted to swing transversely with the lever and having a rotative movement independent thereof.

l. In coupler operating mechanism, a le ver pivoted to a coupler-head, and a rod secured to said lever and having an actuating connection with the lock and being adapted to be rotated about the axis of said lever, said rod being adapted to engage the under side of the coupler-head to prevent the look from creeping.

5. In coupler operating mechanism a lever mounted on an axis arranged longitudinally of the coupler-head, and an actuating connection between the lever and the lock, the said actuating connection being arranged to rotate about the axis of the lever and also to rotate about an axis arranged at right angles to the axis of the lever.

6. In coupler operating mechanism, a lever pivoted to the coupler-head, said lever having an arm portion and a sleeve portion, a rod rotatably mounted in said sleeve portion and having an operative connection with the locking device. I
