Application filed. October 5, 1912. Serial No. 724,008. l L

' to return to partially unexposed position when the'lock is in the lock-set position. This construction was shown and described in our co-pending application, Serial No. 603,858, filed Jan. 21, 1911.

In couplers of the type herein shown, that is, those having a locking block anda separate lifter, a chain is usually extended between the top of. the lifter and the operating rod. It is not uncommon for this chain to become kinked when the lock is placed in the lock-set position or when the knuckle is opened, this because of the fact that the lifter projects considerably above the top of the coupler. When the chain does become kinked the lock will not be permitted to drop and the trainmen experience considerable dilficulty before this can be remedied.

An object of this invention is to provide means whereby the chain cannot becomekinked and also by the same construction, obviate a portion of the danger of the lifter becoming bent or broken by projecting for a great portion of its length out of the top of the coupler.

A further and particular object in the construction shown is to provide a block lock and a lifter the parts being so arranged that the lifter may interlock with the block when in lock-set position and in that position tilt the block ofi the lock-set into uncoupled position. It is a common occurrence for the trainman after having once seated the lock on the lock-set preparatory to parting the cars, to discover that he does not wish to part the train at that point. In that case with the couplers commonly in use it is impossible to again lock the coupler without separating the cars and again bringing them together. By our construction this change of mind is provided for, it being only neccA -corirLING.

Specification of Letters Ifatent. Patented 19115. a

m to shift thelifter aiidtilt the 105k ofi? the lock-set. V t H Our invention-will be more readily understood by reference to the accompanying drawings, wherein,

Flgure 1 1s a slde elevation of a car coupler having a lockand lifter constructed inv accordance with our invention; Fig. 2 is a similar view showing the lock in lock-set position and illustrating the position assumed by the lifter in such case.

Referring moreparticula-rly to the drawings it will be seen that we provide a coupler 10, within the interior of which-is a transverse ledge 11, acting as a lock-set, the top wall of the coupler being apertured to provide a lifter hole 12. A' block lock 13 is mounted withinthe head, this look having a recess or slot 14 in its top wall, this recess being bridged by a staple 15. A lifter 16,, having an elongated aperture 17 in the lower end thereof, cooperates with the staple "and recess. The lower corner 18 of the lifter is not rounded corresponding to the opposite corner, but is squared and corresponds to the top of the lower inner end of the recess .14. When the block 13 is on the lock-set, as shown in Fig. 2, the lifter descends and interlocks securely with the block. In this position the lifter may be moved to the left,

as viewed in Fig. 2, and the lock tilted ofi' thelock-set, the-wall surrounding the lifter hole 12 acting as a fulcrum to accomplish this result. A clevis 19 is secured to the upper end of the lifter 16, by means of a pin 20. v

A chain 21 connects the clevis to the lifter arm heretofore referred to. It will be seen that by this arrangement the center of the clevis 19 is no higher when the lock is in the struction shown and such modifications as are wlthm the scope of our claims, we consider within the spirit of our invention.

We claim: 1. In a car coupler, the combination of a head, a bodily vertically movable locking block within said head, said block having a recess in its top wall, a staple bridging said recess, a lifter projecting through the top wall of said head'when said block is in its lowermost position and having a looped lower end adapted to cooperate with said staple and recess and have limited longitudinal movement relative to said block, whereby said lifter is in partially unexposed position When said block is in lock-set position, substantially as described.

2. In a car coupler, the combination of a coupler head having a lock-set ledge and a 1 top lifter hole, a locking block in said head,

said block having a recess on its, top surface bridged by a staple, and a lifter projecting through said lifter hole when said block is in its lowermost position and having a looped lower end for engagement with said staple, the lower end of said lifter being accommodated in said recess, whereby said lifter is in partially unexposed position when said block is on said lock-set ledge, substantially as described; 7

3. In a car coupler, the combination of a head having a lock-set ledge and a top lifter hole, a locking block having a top recess bridged by a staple, a lifter having a looped lower end for engagement with said block, a clevis on the upper end of said lifter, and a lifting chain, the looped end of said lifter being accommodated in the recess in said block and the upper end of said lifter projecting only partially out through said lifter hole, whereby said lifting chain may remain in substantially the same position in either locked or lock-set position of said block, substantially as described.

l. In a car coupler, the combination of a head, a locking block having a staple, and a separate lifter, the lower end of which has an interlocking connection with said block when said block is held in lock-set position and the lifter released, substantially as described.

c 5. In a car coupler, the combination of a head having a lock-set ledge and a lifter hole, a locking block having a top recess and a staple, and a lifter having a looped lower end adapted to seat in said recess and interlock with saidcblock when said block is on said lock-set ledge, whereby said block may Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
