COUPLER 'Filed oct. 29, 19218 Patented Nov. 20, 1934 i y? COUPLER Edmund P. Kinne, Alliance, Ohio, assignor to American Steel Foundries, Chicago, Ill., a corporation of New Jersey Application October 29, 1928, Serial No. 315,624

- Claims. (Cl. 213-167) This invention pertains, to coupler mechanism, and more particularly to means, for operating a coupler from the side of the car.

An object of the invention is to improve the l operation of couplers,k and more particularly standard A. R. A. rotary type couplers, in a manner whereby the coupler can always be operated Dosi-tively and easily through the medium of the uncoupline rod.

1Q Another` Object is` to provide simple, reliable,

etlicient, and inexpensive coupler operating mechanism having cooperating parts whereby a maximum operating force may be transmitted to the lock for facilitating the operation of the coupler.

1l Still another object is to provide coupler operating mechanism which will fulfill all requirements, of service and manufacture and in which thev operati-ng handle will always seek ai position such that there will be no tendency to disrupt V2Q the parts nor to have any interference with the relative movement of the coupled cars or cooperating parts.

A further objecty is to provide a coupler mechanisml which will effect a great saving inthe number of parts now in use, asfor instance, the elimination of slack devices between the operating rod and the coupling lifter.

Still further object is to provide uncoupling mechanism having lost motion provided therein se tovr permit the return of the operating handle to inoperative position upon release thereof but which has no substantially lost motion between the uncoupling rod and the coupler mechanism in operating the coupler to full knuckle throw position.

' With these and various other objects in- View,

the invention may consist of certain novel features of` construction and operation, as will be more fully described and particularly pointedout 44) in the specification, drawing and claims appended hereto.

the drawing, whichfillustrates an embodiment of the device and wherein like; reference characters are used to designate like parts- Figure 1 is an end elevation of a portion ofv a l railway car embodying the invention;

Figure 2 is a top plan view of the mechanism illustrated in` Figure 1;

Figure 3 is a side elevation of the coupler and 5,0 uncoupling rod mechanism illustrated in Figures 1 and 2;

Figure 4 is a representationk of the. position of the uncouplng rod after release from lock set or knuckle, throw position; and

5,5 Figure 5. is a. sectional' elevation showing. an'

eye connection between the parts of the operating rod, the same being taken substantially in the plane as. indicated by the line 5--5 of Figure 1.

Figure 6 is a View in side elevation of the rotor 60 eye disclosing the oppositely disposed shoulder portions.

The car end sill 10 is provided with the usual operating. gear including the striking casting 11 and associated parts cooperating with the coupler 12, said coupler being of the usual A. R. A, rotary type of the bottom lift type and including a movable knuckle 13 pivoted as at 14 to the coupler head. The lift mechanism, including the link 15 Vfor controlling the operation of theY knuckle 70 13, operates the usual mechanism within the coupler head and is controlled by the lifter 16 pivoted to the link as at 17, said lifter bei-ng rotated through a rotor provided with an eye 18 having oppositely disposed shoulder portions 18a, 75 said rotor being rotatably supported in depending lugs 19 provided on the coupler head.

A bracket 20 is secured to the end sill and is provided with a bearing 21 for supporting the operatingrod 22, said rod being provided with an offset hearing` engaging portion 23 permitting movement of rotation only betweenthe rod and the bracket and depending portion 24 engaging with portion 25 of the bracket so that there is comparatively no lost motion between the bracket and portion 24, this portion 24 being provided with an olset handle portion 26 providing weight tending to. return the handle to inoperative position, as illustrated in Figure S.`

The uncoupling rod 22 is constructed in two 90 parts 27 and 28 to Aprovide lost motion between the parts. and also to provide for movements of the coupler. The parts 27 and 28 of. the unycoupling, rod overlap in normal position, as illustrated in Figure 2, and the parts are respectively 9 5 provided with oiset orclosed eye portions 29 and 30 encircling and vnon-releasably co-operating with the adjacent portion of the operating Arod 22, but the eye being large enough to provide limited rotative lost motion of the uncoupling rod. Portion 28 of the uncoupling rod is provided With a hook portion 31 adapted to have cooperative relation with the shoulder portions, 18a of the leye 18 of the rotor for operating the lifter.

In operation then, the handle 26 is moved up- 105 wardly in a .counterclockvviseA direction whereupon the portion of the rod 27v will impart rota.-

.tion tothe portion ofthe rod 28v through binding of the overlapping portions to thereby lift the lifter 16 and the link 15, causing the cooperating 1.1

mechanism tomove the knuckle 13 to full knuckle throw position. Upon release of the handle 26, said handle will rotate in a clockwise direction to inoperative position, causing the sections 27 and 28 ofthe uncoupling rod 22 to assume the position illustrated in Figure 4, which position is permitted by the lost motion provided by the eyes in said rods. It will be noticed that there is comparatively little or no lost motion between the parts of the uncoupling rod when operated to full knuckle throw position, but ample lost motion is provided for the return of the handle after coupler operation.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to' those skilled in the art without departing from the spirit of the invention or the scope of the claims.
