To aZZ 'whom #may concern:

Be it known that I, ISAAC H.r MILLIKEN a citizen oi 'the United States, residing at Aspinwall, ,in the county of Alleghen and State of Pennsylvania, have inven certain new and useful` Improvements in Coupling-Centering Mechanism; and I do hereby declare the followin v to be a full, clear,

and exact description o` the invention, such as will enable 'others skilled in the art to, which it appertains to make and use thesamc.

My invention relates to that class of car couplers which are mounted on Vrailway vehicles so as to be capable of swinging or moving laterallyI when the cnrs to which they Aare applied pass around curves in the track. 4-

thc invention is to provide av simple and eiiicient .mechanism enab g the tramman whlle standing at the side ofthe car to shift the coupler laterally so as to position it as may Aof my invention is to provide'means for the purpose indientedxthat may be-also employed to etfan unlocking ofe the coupler.' Minor objects of the invent1on, effectedby 'special combinations andfeatures f'e'lemental construction, will hereinaftern pearvr and be particularly omted out inthe c aims.l

Inorder thatthc trainman may shift the coupler laterally to any desired position Vwh ile standing at either' side of" ferrd to employgtwo operating rods or bars 10, one extending toward one' side .of thecar and the other toward the other side, each rod being provided with its own operating mechanism; but it will be understood that only one rod and corrcspondingioperating mechanism may be employed. Since the devices foractunting the rods 10 only one of them has been illustrated, andbut one will be described. i

Movably connected to the outer 4end of each rod 10 is an operating lever l1 the the car, it is prc areidentical,

provide a handle12 that the trninman may grasp when actuating the mechanism. As

shown in the drawings,l the movable eonnection between the rod 10 and lever 11 is preferably a pivotal' one and may be conveniently formed by fashioning the outer end of the rod with jaws 13, which receive the lever 11 between them, a bolt 11 bein' passed through suitable apertures in said aws and lever. In the operation of shiftii, g the-couple'r laterally in one directionthe upper end of the o erating lever engages and fulc'rums` upon a ulcrum member 15 mounted on the car, and, accordingly, to Iinsure1 fe-llicient bearing en agement fof the lever and fulcrum mem er during such operation, the

u dper end of the leverll is preferably proi v1 ed with a rounded head 16 winch-is adapted to engage and rock upon thefulcrum member.

The, upper portion of the fulc'rum member 15 is provided with a plurality of forwardly extending spaced projections 17 which form walls of pockets 18 thatare adapted to' receive the upper end ofthe operating levier 11. One or another of these projections or walls 17,- depending upon which of the pockets 18ithe upper-end of the lever occuples, serves as a fulcrumy orI bearing for the lever to rock upon. To pre vent the upper end of the lever from slipping 'out'of the pocket 18 when the coupler 1s beingshifted, the walls or projections 17A maybe interiorly shouldered, asa-t 19; and to prevent the upper end of the lever from eatchingvupon the outer edges of the walls 17 such outer edges 'are preferably sharp--l cned or beveled,.` as shown'at 20 'in Fig. 4. As a further means'for preventing the lever 11 from'catchin'g ufponv the outer. edges of the walls of the; pockets, the inner face ofthe. rounded head 16 of the lever' may be formed- With a tapering 'or lu 21, as shown in'Fig. 3.

'tion of thelever when in contact therewith is standing, he grasps the handle 12 of the l lever and moves 1t forwardly until the upper end 16 ofthe leverenters the middle pocket 18' of the 'fulcrum member. An extended movement of the leverll, after it has thus vbeen brought into operative'relation to the fulcrum member, causes a rotation of the adjacent rod 10 suiiicient `to unlock the cou ler 1 and to effect the rotation of the nuckle 2 thereof to 'open postiom'ii" the coupler is provided with knuckle-opening mechanism and is not at that `time coupled to another coupler. lVith the upper end of the lever in the pocket of the fulcrum member, the operator pulls laterally upon the lever which, by fulcruming upon one of the adjacent walls 'or fuk-ra. 17, thus transmits a corresponding pull to the rod 10 connected to the operating lever. The coupler is thus caused to -ulove toward the operator.

Should 'extreme 'lateral movement of the couplerbe desired or" should the leverage obtainable when the lever 11 islvin one of the pockets 18'be insuflieient" to permit the trainman to readily shift the coupler to the required position, the coupler 1 may be after which the'upper end of the lever may be transferred to the appropriate adjacent pocket, thus affording better leverage for inducing A:furtherv movement of the coupler.

When the coupler isl to be lshifted laterally away from the-operator, the handle 12 of the operating lever may, if desired, be operated'as .heretofore described to first unlock the: coupler, :afterwhioh it may be iwung rearwardly and upwardly until the ower4 wo o the fulcrum. projections "or bars 22;
