BOTTOM-OPENING CAR-COUPLING.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Original application filed July 3, 1908, Serial No. 441,797. Divided and this application filed March 5, 1910. Serial No. 547,389.

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 a new and useful Improvement in Bottom-Opening Car-Couplers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings. forming part of this specification, in wh1ch Figure 1 is a front elevation of my improved coupler in position, showing the bottom-operating connections; Fig. 2 is a vertical longitudinal section of the coupler; Fig. 3 is a view similar to Fig. 1, but showing a modified form of operating connections; Fig. 4 is a view similar to Fig. 2,

showing the modified form of Fig. 3; and Fig. 5 is a cross sectional. View showing a lock of either form.

This application'forms a divisional part of my application Serial No. 441,797, filed July 3rd, 1908, for a car coupler.

In the drawings, referring to the form of Figs. 1, 2 and 5, 2 represents the coupler body, and 3 the usual swinging knuckle, this being of the usual M. C. B. type. The part 4 is the locking and opening piece, which is preferably of angle form, as shown in Fig. 5, having the locking head 4 and the member 4*, which fits back of the tail of the knuckle, and is adapted to open the same. The lockin and opening piece is provided with a notchor recess 4", adapted to en age a bearing 5 on the coupler, when the lifting piece is lifted and tipped thereon to swing the knuckle open. The portion 4 of the locking and opening piece is also provided with an upwardly projecting hook or eye 6, which is preferably formed on or cast integral therewith, and within this hook or eye fits the bent arm portion 7 of a lifting rod 8, projecting upwardly through a hole in the floor of the coupler. This lifting rod is formed with a vertical slot 9, within which is loosely pivoted a swinging link member 10, by a pin or rivet 18* passing through holes in the bottom portion of the rod. At

the lower forwardly projecting end of the' link member 10 is an eye 11, for receiving the end of the uncoupling rod 12, this eye being forward of the pivotal connection of the member 10, so that when the knuckle is in locked position, the free upper end of the member 10 will move forward by gravity under the floor of the coupler. in front of the hole for the rod, as shown in Fig. 2. This link member, therefore, acts as a stop to prevent the accidental creeping or jumping of the look. When the uncoupling rod is actuated to lift the lifting rod, the first action is to tilt the member 10 rearwardly, so as to free its upper end from engagement with the coupler and bring its upper end portion Within the slot, so that both of these members will be free to rise, either into lockset position, or into knuckle-throwing position. The forward movement of the member 10 is limited by a stop 13, at the lower end of the lifting rod, and its rearward movement is limited by an intermediate stop 14, on the lifting rod, in the rear portion of the slot, which engages the upper end of the link member. The projection 7 on the bent upper portion of the rod engages the hook or eye 6, when the lock is lifted, thus avoiding friction between the rear surface of the lock and the vertical portion of the lifting rod. The lifting rod 8 and the link member 10, though made as separate pieces, are functionally united, in lifting the look, while having motion relative to each other in locking the lock, thus giving an advantage in simplicity and efficiency.

In the form shown in Figs. 3 and 4, the construction is similar to that of Figs. 1 and 2, except that instead of the uncoupling rod 12, I employ a longitudinally extended uncoupling lever 16, whose rear end is pivoted at 17, to the coupler shank, while its forward end is hooked through the eye 11 of the link member 10. This uncoupling lever is operated by an uncoupling rod 18, which extends beneath lever 16, in the form of a crank. When this crank is rotated on its axis, it raises the lever 16 and operates the members 8 and 10.

The advantages of my invention result from the simplicity and compactness of the coupler and opening device in the bottomopenlng coupler.

Many changes may be made in the form and arrangement of the coupler knuckle, the locking and opening piece, and the opening members, within the scope of my claim.

I- claim:
