Application filed October 6, 192 1. 7 Serial No. 505,694,

To all whom it may concern:

Be it known that we, IsAA'o' H. MILLIKEN and WILLIAM J. REGAN, citizens of the United States, residing, respectively, at Aspinwall, in the county of Allegheny and State of Pennsylvania, and Pittsbur h, in the county of Allegheny and State of Tennsylvania, have invented certain new and useful Improvements in Uncoupling Mechanism; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains-to make and use the same.

Our invention relates to uncoupling mechanism for causing the lock of a car coupler to.

perform an unlocking movement. While the'invention is especially designed to provide means well adapted for application to car couplers of the Master Car Builders standard D-type employing a bottom operated lock, mechanism embodying the invention may be also used with other types of couplers as well. y

The principal object of the invention is to provide a simple, compact and efllciently and reliably operating uncoupling mechanism that may be easily assembled or disassembled and in which the parts mutually interlock to prevent their accidental disassociation in service. I y

The principal feature of the. invention,

generally stated, consists in "actuating the lock of a car coupler by, means of a rotatable member which is supported rearwardly of said lock by-means adapted to swing lengthwise of the coupler and to move with the latter lengthwise of the car.

'A- further feature of the invention consists in causing the lock of acar coupler to perform an unlocking movement by means of a rotatable member which is swingingly supported at its center of rotation by means movable with the coupler lengthwise of the car and adapted to swing in said lengthwise direction.

Another feature of the invention resides in actuating the'lock of a car coupler by means of a rotatable member which is swingingly supported rearwardly of the look by a member interlockingly connected to said rotatable member and said coupler in a manner permitting it to swing lengthwise of the latter. I

shown) As will hereinafter appear, there are other features of invention involving particular combinations of parts and special features of construction.

Specification of Lettcrslatent. Patented Mtity 30,1922.

In the drawings illustrating the preferred form of the invention, the scope whereof is pointed out in the claims,'

Figure l is aview, partly inside eleva: tion and partly in verticalsection, of an uncoupling mechanism constructed in acco-rd- 'ance with the invention, the. coupler shown being the well known Master Car Builders standard D-type. I I

Figure 2 is a detail sectional view on the) line 22, Fig. 1, portions of the uncoupling levers and of the couplertcarrier iron and coupler being broken away.

Figure 3 is line 3-3, Fig. 1, portions of the uncoupling levers being broken away. p 7

The car coupler 1 is provided with a lock 2 constructed and operatinglike the locksemplo-yed in couplers of this type. Movablya detail sectionalview on the i connected to the lowerend of the lock 2 and,

projecting downwardly through the lower wall of the coupler head .is'a link 3 which is pivotally attached at its lower end to a lock lift lever 4 that is itself pivotally mounted.

upon the under side o-fz'the coupler. link 3 and its'pivoted lock lift lever 4: preferably conform in structure and mode of operation to the corresponding devices of the standard D-type'coupler. If; thecoupler is designed to have a wide range of'lateral swinging movement it maybe formed near the rear end of its shank with pivot pin opening 5 for receiving a tail pin. (not whereby the coupler may be pivotally connected to the draft gear ofthe car.

Movably connected to the lock lift jlever 4; is a vertically rotatable member 6 which is swingingly supported 'rearwardlyof the coupler lock '2 byv a member? adapted ,to swing lengthwise of the car, thelattermem her being connected tothe coupler 1 so as to be movable therewith in said lengthwise direction. 7 is preferably formed at its lower end with a hook 8 for cooperating with anleye 9 With which the vertically rotatable member The which cooperates with an eye 11 that is rig idly secured to the coupler l, as for example when the parts are assembled, the end of said hook being for this purpose provided with a portion 12 which is adapted to engage the eye 11 and thus prevent .the detachment of the swinging member 7 when the parts are in normal operative relation- As a means for interlockingly connecting the vertically--rotatable-member '6 to the pivoted'lock lift lever 4, the member 6 is preferably provided at its forward end with a hook 13 adapted to enter the eye or opening 14 with Which the member 4 is customarily formed. At its rear end below the eye 9 the rotatable member 6 maybe provided with a centrally disposed recess 15 which opens laterally on opposite sides so as to receive the upwardly extending inner ends 16 of rotatable uncoupling levers 17 by which the member 6 is preferably actuated to cause it to perform an unlocking movement. These uncoupling levers extend toward the sides of the car and may be and preferably are of the well known form illustrated in the I. H. Milliken Patent No.

1,184,116, dated May 23, 1916. The recess 15 may, as shown, be somewhat wider at the bottom than'at the top so as to permit either of the uncoupling levers 17 to be operated independently of the other.

' If desired the coupler 1, instead of being supported directly by the coupler carrier iron 18, mayslidably bear upon acoupler saddle 19 which is mounted upon the carrier iron so as to move transversely of the car when the coupler swings laterally.

Inassembling the mechanism the hook 10 of the swingingly supported member 7 is hooked through the eye 11 carried by the coupler. The hook 123 of the rotatable memher 6 is then hooked through the opening 14 in the pivoted lever 4, which latter is temporarily disconnected. from the coupler, and the member 6 is hung upon the hook 9 of the swinging support. The upwardly extending inner ends 16 of the uncoupling levers 17 are then inserted in the recess 15 of the member 6 and their outer'ends are supportingly engaged with brackets at the sides of the car in the usual manner. WVhen in assembled relation the parts of the mech anism are interlocked so that their ac-cie dental disassociation is prevented.

When either of the uncoupling levers is rotated by the trainman its upstanding por tion 16 engages the rear end of the member 6 and causes the latter to perform an unlocking rotation. During this unlocking movement the member 6 rotates or pivots upon the hook 8 at the lower end of the swinging support 7 while the latter swings lengthwise of the car as may be necessary to permit the forward end of the member 6 to conform to the path of travel of the eye 14 of the pivoted lock lift lever 4.
