CAR-COUPLING.

To all whom it may concern Be it known that I, ARTILUR J. Baznmn', a. citizen of the United States, and a resident of Cleveland, Guyahoga county, Ohio, have invented a new and useful Car-Coupler, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification, in which Figurel is a front elevation of a car coupler constructed in accordance with my invention, and provided with a lock-lifting mechanism operated from above; Fig. 2 is a vertical longitudinal section of the coupler; Fig. 3 is a detail side elevation; and Fig. t an edge view of the lifting link; Figs. 5 and (3 are similar views of the locking de vice for the lock; Fig. 7 is a detail view of the lock; and Fig. 8 is a vertical cross section through the coupler head showing the attachment of the parts to the lock.

Referring to the top opening coupler shown in l to S, 2 represents the cou pler head and 3 is the knuckle of the coupler; and l; is the locking and opening piece of the coupler, which is preferably of angled form, as shown in detail in Fig. 7, having a limiting-head 4i and a member t. which fits back of the tail of the knuckle and is adapted to open the same. The locking and opening piece has also an intermediate member having preferably a notch or recess t" adapt ed to engage the head of the coupler and to tip thereon for the purpose of swinging the knuckle open, as illustrated in Fig. 8. The lower link 5 of the lifting chain is connected with an eye (3 formed on or cast integral with the top of the locking member a and this link 5 has at its upper end an elongated hole 5, a forward projection 5" and a rear projection 5. Between these is an intermediate recess 5.

The upper link 7 of the chain within the coupler head is preferably of fork or clevis form, and is attached to the lower link by means of a pin 7 secured with a suitable cotter. This link has a recess between two vertical walls 7 and 7 divided by an intermediate rib 7 and at the top of the link 7 is an eye 7 through which extends the arm of the tmcoupling rod 8. The link 7 extends through a hole at the top of the coupler head and is preferably made larger at its upper portion, of suitable size to fill this hole Specification of Letters Patent.

when the link is in its lo\\"ermost position so as to exclude dirt from the coupler.

When it is desired to lift the lock, the lifting rod 8 is operated by means of a lever handle 9 so as to lift the links 7 and 5, the link 5 fitting within the fork of the link 7 and being held thereto by a pin 7 which passes through the elongated hole 5. The lifting of the links pulls them into alincment and draws the link 5 into line with the hole in the coupler head and enables it to pass freely through the hole. \Vhen, however, the lifting rod is released so as to permit the links and the lock to descend, the elongated hole 5 will permit the pin 7" to drop downwardly with the link 7, so that the wall 7" of the link 7 will engage the link at the top of the projection 5", and as this point of engagement is back of the atlachnu-nt of the link 5 to the lock at (S, the link 5 will be caused to move lmckward at its upper end so as to bring the inner side of the projection 5* into engagement with the middle rib 7", thus holding the link 5 from further backward movement. The projection 5", being thus brought beneath the upper wall of the coupler head, is held posilivel from rising, and any tendency of the lock to jump or creep upwardly is resisted. it, however does not prevent the free lifting of the links and of the lock, for as soon as the link 7 is lifted it will draw the link 5 into alinement with it and thus free the projection 5" from engagement with the coupler head, taking it out of the path thereof. As the middle rib 7 of the link 7 is between the projections .1" and 5" of the lower link, the movement of the two links relatively to one another is limited and the upper link is kept in a substantially upright position when the lock is raised.

This device may be modilied by applying it to looks of other descriptions, and it may be operated by lifting mechanism other than the kind shown in the Fig. l of the draw ings.

I, claim:

1. A coupler having a swinging knuckle, a lock engaging the knnckletail and movable independently of the knuckle, the top of the lock being below the top wall of the coupler cavity, leaving a space between said wall and lock when the knuckle is locked, and a lock lifting device comprising a plurality of jointed members extending through the space in the upper part of the head and through a hole in the top Wall of the coupler head, said members being arranged to cause the lower member to move laterally by gravity under a stop shoulder on the coupler head to prevent creeping of the lock, and the upper member having an enlargement arranged to seat against the rim of the top hole in the coupler head when the knuckle is locked, the jointed members having a slotted connection and being angled therein and the lower member being held in an inclined position to engage the stop on the coupler head, said members also having co-acting portions which limit their angular movement in both directions.

2. In a car coupler, a lifting link adapted to have a locking engagement with the upper wall of a coupler head, a clevis pivoted to said link and having a slot to receive the upper portion of the link, said slot having a stop portion, and a shoulder on the link arranged to be engaged by said stop to limit the backward movement of the upper end of the link under the upper wall of the coupler; substantially as described.

In testimony whereof, I have hereunto set my hand.
