CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 572,794, dated December 8, 1896.

Application led November lJ 1895. Serial No. 569,082. (No model.)

To coll whom t may concern.-

Be it known that I, JOHN GOETTEL, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Car-Couplings, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of carcouplings that have automatic lateral hooks and is embodied in a device by which the opening jaw is unlocked and thrown open by a single movement, the Object being to make a car-coupling which is self-connecting and self-locking and which can be unlocked and disconnected by the 4movement of one part, which movement may be made bythe trackman without danger to himself. This obj ect I attain by the mechanism shown in the accompanying drawings, in which Figure l is a horizontal section taken through one member of a pair of couplings. Fig. 2 is a perspective view. Fig. 3 shows in perspective the lock-block and a part of its bolt.

As the two members of my improvement are exactly alike, I will describe one of them in detail.

A in the drawings represents the main casting, forming the body of the coupling.

A' and A2 are' shoulders cast integrally with the part A. To the shoulder A', I connect by a pivot-pin B a jaw B B2, Fig. l. This jaw is held in its normal position by a spring B2, located in the interior of the part A and held by a stud B4, as shown.

The object of making the jaw B B2 a yielding one is to prevent its breaking by the shock when two cars are caused to strike violently together. This part of my coupling need not be more fully described, as it is not claimed in this application, and is fully described in Patent No. 388,856, granted to me September 4, 1888 subject, car-couplings.

To the shoulder A2, I attach an openin g and closing jaw O. This jaw C is pivoted on the pin C' and is free to open and close, except when locked closed by the lock-block D. The action of the locking device is as follows: The jaw C has a part C2 extending rearward, as shown in Fig. 2, which part is made with a vertical rabbet C2, adapted to receive the lock-block D when the lock-block is let down into its locking position, as shown in Fig. 2, but when the block D is raised up the rear part C2 of the jaw C is free to swing under it, thus allowing the jaw C to be opened.

To Open the jaw C, I have the followingdescribed device: H is a bent lever .pivoted at H. The upper end H2 of the bent lever H overhangs the top of the block D, but does not come in contact with it except when the block is raised up. Then the bottom of the recess d (see Figs. 2 and 8) will engage with the under side of the arm H2 of the bentleverv ment of the arm H2 will throw the rear extension C2 of the jaw C inward and thus open the jaw and uncouple the cars, or, in case the cars are to be coupled, allow the two members of the coupling to come together and be joined.

The lock-block D is attached by a pin D3 to the bolt D'. This bolt D' serves to keep the block in place and also as a means of lifting the block when it is desired to unlock the coupling and to Open it. For this purpose the bolt D is provided at its upper end with an eye D2, to which a cord, chain, or rod may be attached and by which the bolt and lock-` block may be raised or lowered. If desirable, the bolt D may be connected to a hand-lever and be operated from the side of the car.

It is obvious that the block D and bolt D' may be cast'in one piece, in which case the block D should extend through the upper wall of the shoulder A2 and should have a projection or lug or some other means for engaging with and operating the bent lever H.

It will be noticed that in case the jaw C is open then the lock-block D will rest upon the top of the rear or locking end of the jaw, and that if the jaw C is closed the lock-block will fall into position and lock the coupling automatically.

I claim- In a car-coupling the swinging jaw C having a rearward projection C2 made with a ver- ICO tical rabbet Cfs adapted to receive the lool;- nanle to this specification, in the presence of block D, und the lock-block D: With the bent two subscribing Witnesses, on this '23d day of lever I-I pivoted at H and having an over- August, A.

hanging end H2 adapted to engage with the JOHN GOETTEL. 5 look-block D substantially as and for the pur- Titnessesz pose set forth. H. H. BERRY,

In testimony whereof I have signed my VILLIAM SEARS.
