- a clevis connection in a situation of this sort is objectionable because the nut on the bolt may easily be lost.
- the repair man replacing it on the car may forget to connect the clevis or may lose the bolt which is taken out when the clevis is dis connected for the purpose of removing the coupler.
- the chain connection is particularly objectionable because it is likely to become kinked and thereby, in effect, shortened, with the result that the locking pin of the coupler is accidentally pulled by a normal outward movement of the coupler.
- My invention utilizes, in place of the chain, a rigid link 20 formed preferably with an open spirally formed hook 21 at its lower end engaging the eye 14: of the unlocking pin and with a closed loop 22 through which the crank of the operating rod extends.

- To maintain the connection between the crank and the link I provide a casting 23 formed with stop shoulders 24 and with a slot 25.
- the casting is secured to the end of the crank by a rivet 26, or other suitable fastening means, which extends through the perforation 19, in the crank formerly used for the upper clevis of the chain.
- the link has consider able freedom of movement with respect to the crank of the operating rod. It willslide freely up and down to accommodate for the vertical movements of the coupler. It is capable also of a certain amount of angular movement on the crank to permit the forward and backward movements of the coupler.
- the loop 22 is of a sufficient width so that the coupler is not impeded in its normal lateral movements.
- the link is not, in the preferred form of my invention, capable of axial rotation. For this reason it is possible to use an open hook for making the connection between the link and the eye of the coupler pin without (lan ger that the parts will be disengaged bythe buff- The ing, or rounding curves, for instance.
- the center bracket for example, consists of a strip of metal 28 bent so as to form an upper flange and a lower flange 30, the latter formed preferably with an upturned lip 31; and of a channel-shaped closure piece 32 which fits within the flange 30, 31 of the bracket, and is provided with a shank 33 extending through an opening 34: in the upper flange 29.
- the upper end. of the shank is prefer-- ably bent over at 35 to form a. stop.

- the end bracket 36 may be identical in construction with the center bracket just described. Preferably, however, it is provided with an angular 'stop flange 37 for the handle 16 of the operating rod.
- the rod When brackets of the sort above described are employed the rod may be demounted from the car very expeditiously and without the removal of any parts, such as bolts or cotters, which are likely to become lost. ⁇ Vhcn the rod has been de-mounted the hook 21 can be disengaged from theeye of the locking pin.
- the link does not have to be removed from the operating rod so that the release rigging, when taken from the car, can be handled as -a unit. If a. coupler is to be repaired it is, however, necessary for the repairman to demount the rod, since the shape of hook 21 is preferably such that the link cannot be disengaged from the cou pler with the rod on the car.

- the fixed member thereof. .This arrange rying out the above stated objects, and such.
other objects as will appear from the following description. The invention, however, is
to the exact construction and arrangement shown except so far as certain of the claims hereto appended are specifically so limited.
A The invention is illustrated, in 'certain' ing drawings in which Figure 1 is a fragmentary view,'in perspective, of the end sill andcoupler of a railway car' with the uncoupling mecha nism of my invention applied thereto.

Fig. '7- is a similar bracket opened so that the uncoupling rod may be removed therefrom.
Fig. 8 is a view similar to Fig. 1 showing a modified construction of the supplemental casting on the end of the crank of the operating rod, and I Fig. 9 is a detail perspective of this cast- Referring first to Figs. 1 to 7 inclusive, 10 represents the end sill of the car, 11 the deadwood and 12 the coupler, which latter parts in the several figures of of the parts rod together for supporting the operatview showing the views, in elevationpat right angles to each other, of the connecting may be of any preferred type. The lockof a chain and clevises,
movements of the coupler in drawing,
pin of the coupler is shown at 13 and g 15 is the is formed with the usual eye 14:. operating rod. of the release rigging formed at one end with a handle 16 and at the other with a crank 17. In the chain type of uncoupling mechanism referred to above, the crank of the uncoupling rod is connecte to the locking pin of the coupler by means the end of the crank being flattened, as shown at 18, and formed with a perforation 19 for the bolt of the upper clevis. A clevis connection in a situation of this sort is objectionable because the nut on the bolt may easily be lost. Furthermore, when the coupler is repaired the repair man replacing it on the car may forget to connect the clevis or may lose the bolt which is taken out when the clevis is dis connected for the purpose of removing the coupler. The chain connection is particularly objectionable because it is likely to become kinked and thereby, in effect, shortened, with the result that the locking pin of the coupler is accidentally pulled by a normal outward movement of the coupler.
My invention utilizes, in place of the chain, a rigid link 20 formed preferably with an open spirally formed hook 21 at its lower end engaging the eye 14: of the unlocking pin and with a closed loop 22 through which the crank of the operating rod extends. To maintain the connection between the crank and the link I provide a casting 23 formed with stop shoulders 24 and with a slot 25. The casting is secured to the end of the crank by a rivet 26, or other suitable fastening means, which extends through the perforation 19, in the crank formerly used for the upper clevis of the chain.
The arrangement shown in Figs. 8 and 9 is the same as that shown in the preceding figures except that the casting 23 is provided with another pair of stop shoulders 27 1pn the other side of the loop 22 of the lin It will be seen that the link has consider able freedom of movement with respect to the crank of the operating rod. It willslide freely up and down to accommodate for the vertical movements of the coupler. It is capable also of a certain amount of angular movement on the crank to permit the forward and backward movements of the coupler. The loop 22 is of a sufficient width so that the coupler is not impeded in its normal lateral movements. However, the link is not, in the preferred form of my invention, capable of axial rotation. For this reason it is possible to use an open hook for making the connection between the link and the eye of the coupler pin without (lan ger that the parts will be disengaged bythe buff- The ing, or rounding curves, for instance.
connection is made quite safe if the hook be given the spiral shape shown in the drawings.
The use of an open hook in this connection permits the disconnection of the link from the locking pin of the coupler when the coupler is to be repaired or replaced, provided, however, that the operating rod is removed from its supports on the car.
These supports may consist of any ordinary brackets used in apparatus of this sort but I prefer to employ the special form of bracket shown in the drawings. The center bracket, for example, consists of a strip of metal 28 bent so as to form an upper flange and a lower flange 30, the latter formed preferably with an upturned lip 31; and of a channel-shaped closure piece 32 which fits within the flange 30, 31 of the bracket, and is provided with a shank 33 extending through an opening 34: in the upper flange 29. The upper end. of the shank is prefer-- ably bent over at 35 to form a. stop. The operating rod 15 rests in the closure piece, as shown in Fig. 6, when the rod is in op erative position. When the rod is to be removed it and the closure piece are raised and the latter is turned to the {position shown in Fig.
The end bracket 36 may be identical in construction with the center bracket just described. Preferably, however, it is provided with an angular 'stop flange 37 for the handle 16 of the operating rod.
When brackets of the sort above described are employed the rod may be demounted from the car very expeditiously and without the removal of any parts, such as bolts or cotters, which are likely to become lost. \Vhcn the rod has been de-mounted the hook 21 can be disengaged from theeye of the locking pin. The link does not have to be removed from the operating rod so that the release rigging, when taken from the car, can be handled as -a unit. If a. coupler is to be repaired it is, however, necessary for the repairman to demount the rod, since the shape of hook 21 is preferably such that the link cannot be disengaged from the cou pler with the rod on the car. -If the whole release rigging has to be taken from the car when the coupler is remoyed the chances are that it will be put back on the car when the coupler is replaced. A clevis connection is very easily forgotten. If the hook at the lower end of the link were formed so that it could be detached from its locking pin conditions might arise causing this disengagement accidentally. The apparatus employs no clevises, bolts or devices of that sort. The connection between the operating rod and the locking pin of the coupler consists of a single rigid link having a perm:
nent engagement with the operating rod and a simple hook engagement with the locking 7 .fThese engagements are sufliciently iiexible'for"allfmovements of the coupler.
as long as the operating position there. can be no disengagement as a between the umbupung rigging and the" flocking pin of the coup :At the same timeflthey are positive so" that rod is in its, normal ler.
f l'It will be junder'stood that the locking pin nectlon between the link and crank Finis d w r f will return to its normal as shown in Fig. 8. If the drawattachmentsshould fail the: connection between the operating rod and the locking pin is such that the latter will be automatically withdrawn so as to uncouple the car. from the adjacent car of the train.
