CAR-COUPLING.

SPECIFICATION 'forming' part 'of Letters Patent No. 685,802, dated. November 5, 1901.V Application filed J'nly 20, 1901. Serial No. 69,116. (No model.)

T0 @ZZ whom t may concern:

Be itknown that I, JAMES TIMMS, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

AMy invention relates to an improvement in car-couplings, one object of the same being to provide improved locking mechanism which when operated will throw open the knuckle, but which can be so set as to permit the knuckle to be opened by a pull thereon.

A further object is to provide a single block which can be operated to lock the knuckle, open the same, and which can be set in position to permit the knuckle to be opened, and is designed particularly as an improvement on my Patent No. 678,145,granted me July 2,1901.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view, partly broken away, illustrating myimprovements. Fig. 2 is a top view, partly in section. Fig. 3 is a View illustrating the locking-block removed. Fig. 4 is a viewshowing the latter set. Fig. 5 is a view in section looking at the rear of the knuckle, showing the locking-block in its locked position; and Fig. 6 is a view of a modified form of my invention.

1 represents the coupling-head, to which is pivotally connected the knuckle 2 by a pin 3, and said knuckle 2 being made on its inner end with a tail 5, curved approximately con,- centric with the axis of the knuckle, and the coupling is made with a hollow enlargement 6 to receive the tail of the knuckle when the latter is closed.

7 represents the angular locking-block, which is mounted to move in a chamber 8 in the coupling-head and is confined and operated within said chamber, so that no portion of said block will project beyond the wall of the head,where it would be liable to be broken. The locking-block thus confined is operated by a chain 9, secured thereto and extended up through an opening 10 in the couplinghead, which opening is located to one side of the center of the block 7, so as to give a lateral as well as a vertical pull on the block to tipit to an inclined position, as will more fully hereinafter appear. A suitable cap or closure 10a is secured on one of the links of the chain to close the opening 10 when the knuckle is 6o locked and prevent the chain from falling into the-coupling-head. The block 7 is chambered, as at 11, to form the shoulder 12, which latter is beveled or undercut, as shown in Fig. 4, to engage the hook or seat 19, secured to or formed integral with the head 1 above the tail of the knuckle, the upper face of the hook or seat 19 being similarly curved or beveled,

so as to positively retain the block in its elevated position against accidental displace 7o ment. The block is made with a vertical groove'13 to receive a tongue 14 on the knuckle and securely lock the same in the head. The lower portion of the block 7 is cut away or recessed, as at 15, sufciently to permit the tail of the knuckle to pass freely betweena beveled or inclined lip 16 at the lower end of the block and a shoulder 17, formed by the recess in the block and located abouty midway between the endsthereof, for a purpose which 8o will more fully hereinafter appear.

When it is desired to open the knuckle, th chain 9 is pulled upward to lift block 7, drawing the grooved portion 13 thereof free from the tongue 14, and when the tail 5 of the 85 knuckle alines with the recessed portion 15 of the block a further upward pull on the chain will draw the lip 16 in an oblique direction against the beveled or inclined lower face of the tail 5, and owing to the cam action 9o 0f the lip 16 against the tail of the knuckle throw the latter to its extreme openposition. Vhen the pull on the chain is released, the shoulder 17 will rest on the knuckle-tail and remain thereon until the knuckle is closed, when the block will fall into'its locked position above described.

If cars are coupled together and it is desired to unlock the knuckle Without opening the same, the block 7 is drawn up far enough Ioo to aline the tail of the knuckle with the recessed portion 15 thereon, the chain exerting a lateral as well as a vertical pull on the block, tilting it and pulling the lip 12 over onto the seat 19, secured to orintegral with the drawhead in a position above the tail of the knuckle, as clearly shown in Figs. 1 and 4, and as the lip 12 and the seat 19 are slightly inclined the block will be retained in this inclined position, and thereby make it difficulttoshake or jar it from off its seat. When the cars pull apart, the knuckle will be drawn to its open position, and the tail thereof will move through the recessed portion 15 of the block and support the latter during its opening and closing movement.

The upper face of the tail of the knuckle from the tongue 14 rearwardly is approximately fiat or horizontal, as shown at 5a, for

-the purpose of permitting the knuckle to turn in its opening movement some little distance before engaging the shoulder 17 of the locking-block for dislodging the latter from its set position, and the upper surface of the curved edge of the tail from the point 5a to its 'rear end is upwardly inclined to engage the shoulder 17 of the locking-block and disengage it from its seat 19. The upper surface of the tail between the pivot-pin and the outer curved edge is made slightly convex or is inclined upwardly from its curved edge toward the pivot-pin of the knuckle, so as to engage the shoulder 17 near its free edge or its edge adjacent to the tail, and thus cause the locking-block to tip outwardly and carry the lip 12 out of the path of the hook 19, so

vthat in the locking action of the knuckle when the locking-block is supported wholly on the tail of the knuckle the lip 12 descends in a plane outside of the plane of the seat 19,

thus permitting the block to fall to its lockedposition Without interference.

The locking-block is,as before stated chainbered to form a beveled shoulder 12, which when the block 7 is raised so that the locking-surface thereof clears that of the knucklearm it (the lock) will by reason of the diagonal or oblique movement given it by the chain engage with or rest on the corresponding seat or projection 19,t`ormed on the coupling-head, and thus hold the lock in a suspended position independent of the knuckle-tail when the latter is in its closed or locked position. The locking-block 7 maintains this independent position relative to the knuckle-tail up to a position of the latter between that of fully closed and fully opened.

As the knuckle-tail swings outwardly a point in its movement is reached when it engages the locking-block, and continuing its movement moves the latter up and away from its support, completely disengaging the two, as before explained, and thus carrying the lock on the upper surface of the knuckletail and putting it in a position to drop into a locked position when the knuckle-tail shall have been swung to a closed or locked position.

In Fig. G I have shown a construction wherean opening 21 in the wall of the couplinghead. locking-block is at or near the top of the lat- .70757 In both instances the support of the V: l.

It sometimes happens that after the lockk Y Y has been set it becomes necessary to again 1 lock the knuckle without permitting the latter to open. Y

can be accomplished by inserting the finger, stick, or any other object through the hole 22 from its seat.

plished by simply pushing the tongue on the block, which is exposed through the side, offy its supportingseat.

Various other slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my ,in-

vention, and hence I would have it under- V8o been set the lock remains so until released.V Should itY therefore be desirable or necessary to lockV jA the knuckle without first opening same, thisV f 7.

stood that I do not wish to be limited to the f precise details set forth, but consider myself at liberty to make such slight changes and4V alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a car-coupling the combination with a draw-head, anda knuckle mountedtherein,

of a locking-block having a shoulder located at or nearits top and adapted when elevated to engage a seat within the coupling-head above the knuckle for suspending the block in a position to be engaged by the tail of the f f knuckle as the latter moves to its open position. Y Y

2. The combination with a coupling-head and a knuckle pivotally supported therein, of

a locking-block inclosed within said head and Y.

provided at or near its top with a shoulder Y adapted to engage a seat within the head Y 1220y .7

above the tail of the knuckle, the said block normally located in position to lock the knuckle and means thereon for throwing the knuc- Y 'Y kle open, substantially as set forth.

3. In a car-coupling the combination with tially as set forth.

4. In a car-coupling the combination with draw-head and a pivoted knuckle, the drawhead having a seat above the knuckle and an opening through its wall adjacent to the seat, of a locking-block for locking the knuckle in place and provided near its upper end with a shoulder, which when the block is raised to uncoupling position, rests on said seat in the draw-head.

5. In a car-coupling a knuckle having a rearwardly-projecting tail, the said tail having its lower face inclined upwardly from its front to its rear end, and its upper face approximately horizontal from its front edge rearwardly a distance to permit the tail to move within a recess in the locking-block without engaging the latter, and then inclined upwardly so as to make contact with said locking-block.

6. In a car-coupling the combination with a draw-head, and a knuckle pivotally mounted therein, and having a rearwardly-projecting tail, of a locking-block inclosed within the draw-head, the said block provided with a beveled lip to engage the tail of the knuckle, said tail being constructed to permit the block to remain inert during the early opening movement of the knuckle, and by the continued movement of said tail, to be disengaged from its seat and deposited on the tail and maintained thereon in a position to lock automatically during the closing movement of the knuckle.

7. In a'v car-coupling, the combination with a draw-head and a pivoted knuckle, of a locking-block inclosed entirely within the drawhead and provided with a beveled lip to engage the tail of the knuckle and open the knuckle, said locking-block normally disposed in position to lock the knuckle, rigid supporting means within the draw-head to hold the locking-block out of its locked position, and a tail on the knuckle to release the locking-block from said unlocked position.

In testimony whereof I have signed this speciiication in the presence of two subscrib` ing witnesses.
