Definitions

  • This invention relates to fixed jaw or Willison couplers of the type which includes, among other usual internal parts, a lock-set piece which enables the coupler to be placed in a lock-set condition.
  • a lock-set piece which enables the coupler to be placed in a lock-set condition.
  • Willison couplers equipped with lock-setting mechanism it is frequently desirable because of inadvertence or a change in train-makeup plans, to take a lockset coupler out of lock-set condition.
  • the above and other objects which may become apparent below are accomplished in the coupler of this invention by improvements in the lock-setting mechanism.
  • the essential improvement on which this invention is based resides in a lock-set piece comprising a resiliently supported rearward facing member, such as a spring or a spring-supported element, against which the lock-throwing rotor may rest in a position thereof wherein it holds the lock in its coupler unlocking position.
  • a lock-set piece comprising a resiliently supported rearward facing member, such as a spring or a spring-supported element, against which the lock-throwing rotor may rest in a position thereof wherein it holds the lock in its coupler unlocking position.
  • the opposing coupler is fully entered into the host coupler to hold the lock-set piece in its normal operative position.
  • the resilient member of the lock-set piece is sufiiciently resistant to the return of the lock-throwing rotor to its normal position of repose corresponding to the forward locking position of the lock to hold the rotor in retracted lock-set position against normal contingencies. However, it is readily yieldable to manual actuation imposed thereon through operation of the coupler-operating lever.
  • FIG. 1 is a perspective exploded view of the various components (the coupler head shown in section) of a coupler in accordance with the invention
  • FIGS. 2, 5, 6, and 7 are fragmentary side elevations with a foreground wall of the coupler head removed, illustrating the coupler of FIG. 1 assembled and in the various conditions indicated;
  • FIGS. 3 and 4 are side elevation views of modified lock-set pieces.
  • the coupler of the invention comprises a head 5, a lock 6, a lock-throwing cam 7, an anti-creep element 8, a lock-set piece 9, an indicator element 10, a rotor shaft 11 combining with cam 7 to form the lock-throwing rotor of the coupler, a pin 12 cooperating with the rotor 11 and a portion of the housing not shown for securing the rotor in the coupler head, and a pin 13 normally extending through the base portion of the coupler head shank 14 to support the indicator 10.
  • the lockset piece can then be lifted manually to a level releasing a portion of the lock-thrower engaging the rear facing surface 23 of the portion 21. Due to the center of gravity built into both the lock-throwing rotor and the lock, both drop forward as soon as the lock-set piece releases the rotor.
  • each is constructed with a yieldable, resiliently-supported member providing a rearward facing cam surface corresponding to surface 23 of the prior art piece of FIG. 8.
  • the lock-set piece in FIG. 1 has a recess 25 similar to recess 26 of the prior art lock-set piece 20.
  • the underside of the lower leg 33 of the spring 30 is engaged by lifting-means such as a trunnion-like boss or lug 36 extending laterally from one side of the lock-throwing cam 7 to lift the piece 9.
  • lifting-means such as a trunnion-like boss or lug 36 extending laterally from one side of the lock-throwing cam 7 to lift the piece 9.
  • the lug 36 passes rearwardly of the junction of the legs 33 and 34 into the recess thereby allowing the lock-set piece to settle back down to a level at which a surface defining the upper extremity of its elongate aperture 37 rests on a supporting trunnion 38 therefor fixed to a side wall 39 of the head 5 (FIG. 6).
  • the upward leg 34 of the spring provides a rearward-facing surface engageable by the lug 36 as shown in FIG. 6.
  • the lock-throwing cam 7 is shown in engagement with a cam-following surface 31 of the lock, and supporting the lock against its strong tendency to return to the position shown in FIG. 2 by reason of its center of gravity being located substantially forwardly of a pivotal point of support on the bottom wall of the coupler head at 42.
  • the lock-throwing cam 7 is in turn supported against the rear facing surface of the spring 30 provided by the leaf 32.
  • FIG. 7 illustrates the function of the lock-set piece 9 giving rise to the present invention.
  • the coupler as illustrated by this figure, is in a transitory condition, i.e., at a stage of forced return movement of the lock-throwing rotor wherein the lock-throwing cam has engaged the leg 36 and deflected the spring 30.
  • the capacity of the spring to resist angular displacement relative to its upper cantilever support is being overcome by torsion forces exerted on the shaft 11 through a lever system not shown.
  • This lever system may take the form of that conventionally provided on ailway cars including the conventional operating rod having handles at both sides of the car. The direction in which the various components are moving is indicated by arrows placed on such components.
  • the lock-set piece 9 is shown in FIG. 2 in the position it normally assumes when engaged by a couple fully entered into the host coupler.
  • the lock-set piece comprises a pad 47 by which it is engaged by an opposing coupler.
  • the lock-set piece rotates forwardly or clockwise as viewed in the various assembly figures in a manner known with respect to the prior art piece 20 of FIG. 8.
  • a lug 48 thereof engages on an upper surface 49 of the anti-creep element 8 whereupon the element 8 is rotated clockwise to carry its rear end portion downwardly out of alignment with a rear wall surface 50.
  • surface 50 is the stop primarily for the element and secondarily for the lock in anti-creep function, positioning of the rear portion of the element 8 for passage into the interior of the shank 14 prepares the lock for free rearward movement necessary for automatic coupling.
  • FIG. 4 illustrates a modified lock-set piece 16 which comprises a spring 51 of single leaf construction.
  • the springs of the lock-set pieces 9 and 16 are supplanted by a pivoting cam follower 54 having a lower portion 55 of dihedral conformation conforming to the arrangement of legs 33 and 34 of the spring 30.
  • the follower 54 is connected pivotally in the upper portion of the recess 56 by a pin 57 to a bearing portion or web 58 of the lock-set piece body.
  • a compression spring 59 stands between the cam follower 54 and the supporting arm 61 for the pad 62 used to engage an opposing coupler. counterclockwise movement of the follower 54, as seen in FIG. 3, is limited by engagement of a hub extension or lug 63 with a rearward-facing surface 64 of the lock-set piece body.
  • said piece comprises yieldable means resistant to free return movements of the thrower at said rearward position of the piece and defining a substantial portion of the piece and defining a substantial portion of said surface of the recess, said yieldable means being yieldable relative to the remainder of said piece to an extent enabling forced return movement of said thrower to its forwardmost position.
  • the yieldable means is a multiple-leaf spring attached cantilever fashion to the remainder of the piece by an upper end portion and tapers downwardly, said spring having a horizontal leg formed by an exten- 6 sion of one leaf, and another leg extending upwardsaid follower is in pivotal relation with the remainder ly from a junction of the legs, and said horizontal leg of said piece. provides said downward-facing surface and said other leg defines substantially said surface of said References Cited recess. 5 UNITED STATES PATENTS 5.
