COUPLER-PIN LIFT.

, Application filed May 31, 1923. seriaino. 642,693.

This invention relates to car coupling devices and more particularly to the uncoupling mechanism or devices for lifting the coupler or locking pins of couplers employed for connecting the cars of railway trains and the like.

Oneof the objects of the invention is the provision of newand improved uncoupling rigging or mechanism that is constructed of a minimum number of parts but at the same time will permit the necessary longitudinal, lateral and vertical movements of the coupler, incident to the travel of the car.

Another object of the invention is the provision of a simple, strong and durable improved device of this character which may be easily manipulated and one that is efficient and reliable in operation. 7

Other and further objects and advantages ofthe invention will appear from the fol lowing description, taken in connection with the accompanying drawings, in which Fig. 1 is a plan view of a portion of a railway car showing the invention in position thereon, parts in section and parts broken away;

Fig. 2 is a front elevation of Fig. 1 with the coupler removed and with parts broken away; 7

Fig. 3 is a side elevation of Fig. 1; and

Figs. 4: and 5 are details of a modified form of the device.

On the drawings, the reference character 10 designates a car, and 11 a coupler there for including a coupler pin 12 for locking the knuckle 18, all of which are of the usual or well known construction.

Referring to Figs. 1, 2 and 3, a horizontally arranged rock shaft 14 is pivotally or rotatably mounted in loops or brackets 15 and 16 suitably secured along the endoof the car. The outer end of the shaft 13 is provided with the usual laterally extending arm or handle 17 by means of which it is turned or rotated. The shaft l is also provided with an apertured flattened portion 18 which is normally in horizontal position. The parts are so arranged that the flattened portionis in a substantially horizontal plane while the arm or handle ex tends downwardly. v Suitable mechanism connectingthfi shaft and the in 1.52. provided :tsti

, eacept, that the fzfr'i.-.

the knuckle 13. This mechanism is so con recess forv engaging the flattened portion of the rock shaft. In other words, the arm is bifurcated at its inner end, forming the plates 23 and 24 which engage each side of the flattened portion and are provided with.

suitable apertures through which the pivot pin 19 may extend. Thepivot pin merely holds the. parts in assembled relation. This interlocking connection between the arm and the shaft causes the arm to move when the shaft is rotated. From the pivot 19 the arm extends downwardly and outwardly at an angle to the shaft 14 and has its free end bent, to. extend substantially parallel with said shaft for slidably engaging the eye of the pin 12, the free end of the arm being reduced for this purpose, as shown at 25.

The end 25 of the arm 21 makes a: loose fit in the eye of the pin 12 in order to permit sliding, turning and a limited pivotal movement of the end 25 in the eye 12. By this arrangement, vertical movement of the pivot 19 and a slight pivotal movement in the eye 12.

The modified form of thedevice shown in Figs. 4 and 5 differs from that just described only in the manner in which the arm is pivotally connected to the rock shaft. In this form, an interlocking connection is provided for this purpose whereby the use of a pivot pin is unnecessary. As shown, the rock shaft 14. is provided with flatteaed pertion ,18 arrame as, in the other forth rear sages struck on the arc of a circle from the center of the flattened portion, as shown at 28. The arm 21 is provided with an'elon'gated recess or slot 26 having curved ends to correspond with the curved edges 28. The shorter dimension of the recess orslot is slightly less than the diameter of the rock shaft. The recess or slot has a lateral extension 27 in one wall arranged at right angles'to the arm whereby the arm may he slipped in position on the shaft by turning thes'a-rne at right angles thereto so that the round portion 29 on the corresponding side of the shaft 1 9 will register with the depression. After the arm engages the flattened portion, it is turned to thereby prevent its removal. \Vhile the shaft and arm have been described in both forms of thedeviceas being provided-with a flattened portion 'and :a' recess, respectively, it is understood that the parts maybe interchanged, if desired. The operation ofthis form of the device is substantially the same as that just described.

It will be understood that various changes in the form, construction, composition and arrangement of the several, parts 'may be resorted to'without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictlyto the structure herein-set forth, but f hat I claim is':

1. In a device of the class described, a rock shaft, means for operating said shaft, an arm having a slot. in one end for engaging said shaft, "and apin extending through said shaft and the slotted end of said arm for pivotally connecting said armtofsaid shaft, said arm extending at an angle to'sai'd shaft and provided with an extension for operating coupling pin. t

2. In a device of the class described, a rock shaft having a. flattened portion between its ends, a handle forxoperating said 'shaft,'an arm, means for; pivoting said arm to said flattened port-i'onwhereby the latter may function as a lever to raise said pin, and means on said arm forslidably engaging the eye of'a coupling pin.

3. In combination, a car, coupler mechanism for said car including a coupler pin, a comparatively straight rockshaft memher, a pair of bearings for rotatably'mounting said rock shaft member on said car, an arm member pivotally connected to said rock shaft -member between said bearings,

one. of said members being provided with a distorted portion and the other withme'ans for engaging said distorted. portion, and

"means for holdingsaid members inpivotal 6O engagement. ,7 a I, 4. In combination, aifcar, coupler mechanism for said car including a coupler pin,

' "a'rock shaft comprising an approximately straight body portion, "ands'a handle portion extending at an angle therefrom, means for wardly "extending handle at its outer end,

and having aflattened intermediate portion in a plane at right angles to said 'handle,an arm-having one end bifurcated for engaging said flattened portiomanda pin extending downwardly through said flattened. portion and the bifurcated end o'fsaid arm, said arm being provided with an off-set portion for slidahly engaging anxeye in the upper 7 end of said pin. a v a 6. :In an uncoupling mechanism for ra l way cars, a rock'shaft'com-prising a substantially straight body'portionand an operatinghandle secured to said body portionand extending at an angle therefrom, means for rotatably mounting said shaft on'a car, an arm, a pivot extending parallel to saidhandle and pivotally connecting said, arm to said body portionand meansrigidly connected to said arm for'slidably engaging the eye of a'coupler pin for operating the same.

7. In combination, "a car, coupler mechanism therefor including a coupler pin provided with aneye, a -substantially straight rock shaft comprising a substantially straight body portion, means for rotatably mounting's'a'id body portion on said car, an uncoupling arm, a normally vertically a'r ranged pivot connecting said arm to the straight body portion of said shaft, said arm being provided with'a reduced portion for ivotallly' and slidably engaging said eye for permitting relative lateralandvertica'l'movements betwe'ens'aid arm and said pin, and a handle-on said shaft normally extending downwardly for rotating said shaft to elevate said arm and pin '8 ln'combination, acar, coupler mechanisrn therefor including acoupler pin havan interlocked pivotal connection with said shaft between said bearings, saidconnection being adapted to elevate or depress said a'rni whensa'ld shaft is rotated in one direction "or the other, said arm beingprovided with means for rotatably and slidably engaging "said eye, and a handle for rotating said shaftfor lifting said fpin.
