L'h all whom it .tay concern:

Be it known the.. l, ARNOLD STUcKi, a. resident oi Allegheny, isz the county of Allegheny' and State of Pennsylviini., have invented a new and useful improvement in Car-Couplers; end I do hereby declare the following to be a full, clear, and exact description thereof. This. invention relates to car-couplers of vide n. couplerprovided with knuckle-locking ineens so arranged that it cannot creep or juinp upuiider the iolting of the car and riccidenta ly unlock the knuckle, which can be 'set in unlocked osition, so that it need not he held by the rakenien even though the cars do not immediately pull spart, which will be dislodged from seid set position when the knuckle open, end'which is also arrenged to throw open the knuckle.

The invention consiste in the special construction and arrangement of parts hereinafter described end cieiined.

ln the accompanying drawings, Figure i is a plan view 0l' 'my improved coupler, showing the knuckle in unlocked position. Fig. 2 is a horizontal section of the companion coupler, teken on the line 2 2, Fig. 4t, and showing the knuckledn loclredposition. Fig. 3 is a. siniilar View taken on the line 3 3, Fig. e, and showing the knuckle in unlocked po- Fig. 4 is e vertical longitudinal section onthe li'ne 4 Il, Fig. 1,'showing the lock ing-hlock in locking ositioii. Fig. 5 is e similar view showing t e locking-block in uil-- locked set position. Fig. 6 is a. similar view showing the locking-block at its extreme upper osition. Fig. 7 is a horizontal section on tie line 7 7, Fig; 5. Fig. 8 is c view looking lupwardly into the recessed head, end Fi s. 9 `and 10 are perspective views of the loc ing-block.

My invention may be applied to any automatic car-coupler having a pivoted or swinging knuckle. lt comprises e, suitable head 1,

.having therein e recess or chiiinher 2 and provided. with lugs 3, between. which the knuckle 4 is pivoted by ineens' of the pin. 5.

V The heed is also provided with the horn 6, as

is common iii this type of couplers, and with the shrink 7 for sttachincnt to the draft mechanism.

The knuckle is provided with a teil 8, which projects heck into the recess 2 of the heed and which at its end is provided with the hook 9 `for engaging a lug or similar inea-ns l() on; the heed, so as to prevent the `knuckle swings open.

knuckle from pulling out even though the ivot-pin 5' should become broken ci lost.

The lifting-chain, link, or rod is attached to the block eceeiitricelly, being shown loceted in front of the center of gravity oli said block. The hole 19 in the floor of the heed ol or parallel with the exis of the coupler.

This block is sub# The floor of said heed is higher et the rear of seid slot at 24 than it is et the front end of seidslot. The recess in the heed .is provided with suitable ouides 25 for guiding the `block verticallvend et its upper portion is provided with oppositelydncliiied feces 26 and 27, which serve to rotate the hloek on .its vertical exis. The Awell et the 'iront ci" the recess is provided with nninwnrdlyproiect ing lug, shoulder, or ledge 28, which lies enh stantifilly in the piene of tlie'top ci the lolock when in its locking;r position. v

The kniickleeteil is provided Wit? verLA ticzil fece 129, iigsinst which the end ci the erin 17 beers when throwing the knuckle open. This erin nojecte upwardly end then curves downwei' ly and in the locked position ol the oiirts lies in fi cavity 3G, formed'in the tail of t e lgiuckleithis hein done merel lto save space. .i lll/"hen the kinic. le is locke the hook 9 on 'its teil will engco'e theiug. lil -onv the couplerhecd, the locking-block i3 l2 on the knuckle-tail, and. its opposite end' bearing afainst the wall 31 ofthe headreeess. T e block, therefore, has a solid thrust-bearing on the side op osite to the knuckle-tail, so that it is impossi le to break or bend said block. The-arm 17 projects above the tail, and its outer end 32 rejects down into the cavity 28 of the knuc le-tail. The block 13 will rest upon the licor 20 of the head, and since the rear part of the floor is igher, as at 24, this block will be supported n Y at its rear edge, and consequent y will tip forward by gravity. This will bring lits upperjrcnt edge underneath the ledge 28, and as a consequence if said block should jump er cree upwardly under the jolting of the car it wil merely strike against this ledge and cannot accidentally unlock the knuckle.

' W hen the knuckle is raised by means of the lifting-chain 23, the first effect is to swing said lock on its transverse horizontal axis, thus straightening same and withdrawing its front upperedge from 'underneath ledge 28. Then said. block will move vertically until it clears or releases the tail of the knuckle and its lower edge is above the ledge 28. lnasmuch as the lifting means is attached eccen- .rically to the block, said block will swing so that its'front edge will be over the ledge 28. Consequently, ifthe cars are jammed tight together the brakeinan need not hold the operating-lever until the cars pull a art, but can at once release the lever and liiave his position. The block will merely fall by gravity until its forward bottom edge rests en ledge 28, thus being in lock-set7 position. Vhcn the cars pull apart, the tall of the knuckle will swing out underneath the bloek and the curved end 1l thereof will bear against the cur-ved face 2l on the prong or pin 1S, thus shoving the saine baelfiwardly sufficiently to dislodge the block from the ledge 258,k and said. block will then drop by gravity and rest upon the end of the knuckletail. '(.onsequentlw when the tail again swings inwardly when coupling the cars the block will be free to fall by gravity to locking position. lf the knuckle has swung open before the brakeman releases the operatinghandle, the lmucklc-tail will bear against the pronr 18 and hold it so far back that when the lilock drops it will not strike 'the ledge 28, but will come to rest on the tail of the knucklo, Consequently, when the knuckle swings to locked position the block will drop by gravity to lock said knuckle and will automatically tip forwarr-lly, so that its front edge will come underneath the ledge` 28.

The block moves substantially vertically l.: a height somewhat greater than necessary to release the knuckle-tail. At its extreme upper movement the inclined faces l5 aiid 16 on the upper `side of said block contact with ond, a vertical sliding the oppositely-inclined faces 26 and 27 on the walls of the head-recess. As a consequence said block will be given a rotary movement on its vertical axis, of this movement being such as to swing the arms 17 around, so that its end will engage the face 29 on the knuckle and swing the same open. It will be observed that this knuckle-throwing movement of the lookin block does not occur until the knuckle is ful y;

released, so that unnecessary 'friction isV avoided. The block, however, is given sufficient rotary movement to throw the knuckle entirely open. 4,

The locking-block hasthe following movements: first, a forward tipp its rear edge to come un er the ledge 28 ,sec-

moveinent; third, a reverse swinging movement on its horizontal transverse axis due to the eccentric connection of the lifting Ameans to the block, and the fourth, a rotary motion on its vertical axis occasioned by the oppositely-inclined faces on the roof-walls and upper face of the block. The in or prong 18, projecting through the s ot 19 in the floor, guides and steadies the block during these movements, permits said Vblock to swing on its transverse horizontal axis, merely riding along one ofl the walls of the slot. lts rounded lower end serves practically as a pivot to steady lthe rotary movement of the block, and said prong also prevents movement of the block transversely in the coupler-head.

While both the block head are shown as provided with oppositelyinclined faces, this is merely to prevent friction. lt would be suiiieient if one member only had such faces, and, indeed, a spiral groove or rib on one member engaging a lug on the' other would answer the purpose.

lt is obvious that many changes may be made in the details of construction of this coupler without departing from the spirit of my invention. lt is extremely simple and cannot get out 0f order. The means of unlocking and opening the knuckle, together with the lock-set feature, is all accomplished by the use of a one-piece block, thus greatly simplifying the device and rendering it less liable to derangen'ient.
