To all whom it may concern: H

Be it known that I, WVI LIAM J REGAN, a citizen of the United States residing at Pittsburgh, in the county, of Allegheny and State of Pennsylvanimhave invented certain new and useful Improvements in -Uncoupling: Mechanism; and I do hereby declare the following to be a full, new, and exact description of the invention, such as will enable o'thers skilled in the art towhich it appertains to make and'usethe same; My invention relates l to uncoupling mechanism for operating thexlock of ar car coupler. While it is especially designed to provide uncoupling means particularly applicable to the Master Gar Builders? D- 'type coupler employing a bottom operatedlock the invention may be embodied inuncoupling mechanism applicable, to other forms of couplers as well. a ,1,

The primary object of the inventionis-to afford an easily operated uncoupling mechanism which consists of a few simple parts -compactly arranged so as to enable the device to be capable of being applied; in a space of comparatively small verticaldimension. it 3 The principal feature of the invention, generally stated, consists in movingthelock of the coupler by means of a rotatable'mem- ,ber operatively connected to the lock and slidably supported near its rear end by anactuating member that is pivotally connected at a point below the said rotatable member to a movable support adapted tofswing lengthwise of the car. A further feature of theinventionjconsists in moving the lock of a coupler to unlocked positions by means of a rotatable member operatively connected .to the lock and'cwhich slidably engages an actuating member that is'pivotally connected to the lower end-not an inverted bail whose upper endisprovided with a plurality of hooks whereby the bail may be swingingly and detachably supported by the couplercarrierironr,s v

As will hereinafter appear, thereare further features of the invention residing in particular details vofconstructionandri n special combinations of parts, f 1;; 41:;

The member 7,, which is preferably formed as a simple bar, is slidably supported rearwardly oft-he coupler Lock 2 by a member 10 which, uponbeing actuated, is adapted to cause the bar 7' to perform a vertical rotation .resu'ltin inv an unlocking movement of the couplerfijock. The, actuating member 10 ispivotally supported at a point below the, rotatable bar7 on, the. lower part of an invertedbail or; U-shaped" member 11 whose upper end is provided With a i v plurality of spaced hooks 12- affording means for effecting a pivotal connection with: the carrier iron allowing said bail to. swing lengthwise of the car. In the construction shownin the drawings the carrier iron device 6 is illustrated as'having riveted thereto a'bracket member 13 provided with a transversely elongated slot 14 for detachably receiving theho0ks-12' of the swinging bail; The pivotal connection between-"the actuating member 10 and the swinging bail 11 is preferably effected by providing the lower end of said actuating member with a bounding side walls 19 of the actuating member 10 being provided above the point of pivotal connection ofsaid actuating nember to said bail with apertures 20 permitting stead of upwardly,

the introduction of the bent ends 1170f the uncoupling levers and forming journal bearings for said levers 18'. Except thfit it is preferred to extend the bent inner ends 17 of the uncoupling leversdownwardly in said levers maybe of the well known form illustrated in the I. H.

Milliken Patent No. 1,184,116, dated May The actuating member 10 is provided with a forward wall 21 adaptedto be engaged by the bent ends 17 of the uncouplingle'eers to efiecta lock actuating rotation of the member 10 "when either of the independently rotatable unoouplng levers is operated by the trainma'n to cause an unlocking movement the rear of the uncoupling levers 18, is a transversel extending lug portion 22 adapt ed to engage the rotatable bar 7 when the mechanism performs an unlocking operation, the rotation of the actuating member 10 induced by the movement of either of the uncoupling levers 18 thereby being communicated to the member 7 through the engagement therewith of the transversely extending portion 22 and the upper end of the front wall 21 of theactuating member 10.

The rotatable member 7 may be caused to erform an unlocking operation by manipuating either of the uncoupling levers 18. When either of said levers is rotated in the proper direction its bent inner end 17 presses against the forward wall 21 of the swinging actuating member 10, causing vthe latter to rotate upon the supporting bailll. This results in bringing the portions 21 and 22 of the actuating member into engagement with opposite sides of the rotatable member 7, thereby compelling the latter to executean unlocking movement and thus causing the lock 11ft lever 4; and link 3 to communiof the member 7 and its actuating means 10 the supporting bail 11 swingslengthwise of the car as may be required to permit the forward end of the rotatable member, 7 readily to conform to the movement of the lift lever 4. 3

While the several parts of the mechanism are detachably connected and may therefore be easily assembled and disassembled they are interlocked so that accidental disassociation is prevented when the device is in service.
