In this way, the' extending push portion 20, which engages the curved rear face 21 of the knuckle tail 4, to push the knuckle open after unlocking.

The operating lug16 of the lift lever perform s the functionsof lifting the locking blockand of coeperating therewith to act asia-lock for the lock to prevent creeping thereby, while theleveriitself, carrying the lock, acts to throwthe knuckle open. The

' lever- 17 being loosely pivoted, any tendency of the locking block to. creep upwardly will cause'the lower shoulder 23 on the locking block to abut against the angular shoulder of the lug16 andjam' in such a way as toprevent further upward movement of the look. When, however, a lifting force isappliedto the lever'17,--there is no jamming and the lug 16"aots upon the upperwall of the recess 15 to liftthe lock.

. The lock-settingis performed in the following manner: The lug16 is provided with an angular corner portion for part of its Qsurface, and as theleverl'Z is pushed upwardly, its frotation brings the angularcoriner portionof the, lug 16 intoengagement with a-shoulder 22, forming part of the upper wallof the recess 15, which recess is enlarged forwardly as shown inliigs. 9 and 10. This angular portion .of the lug also engages a similar shoulder 23, in the bottom wall of the recess, thus giving the lock to the lock feature.

It will be seen that, owing to the-angular shape of the lug 16, its coaction withthe shoulders on the top and bottomwalls of the lock recess prevents accidental upward movement of the lock and also causes the engagement which gives the lock set.- When the parts are in the normal locked position,-

- any, accidental upward movement of the locking block will cause a toggle-like action between the lowershoulder 23 and the angular shoulder of 'thelug, since the lug in its rotation willcarry the angular portion out away'from its pivot, and thus tend to jam the vertical face of the locking block against the wall of the coupler. This same action ocours in the lock-set position when the a'ngu lar portion engages the upper shoulder 22 afterthe locking block has been raised to the.

lock-set position. In one position ofrotation of the lever 17, the-lock will be held in lock-set position, whilefurther rotation will causethe lug 16 to ride'along the inclined face 2 1, without furtherwlifting of the lock, During this further rotation, the extended The lock lock lift lever upwardly.

end 20 of the lever 17 will push the knuckle open. During this opening movement, the

lock will be held up by the engagement of the lug 16 with the inclined top recess wall until the tail nears.the end of its movement, when its rising upper surface will engage and support the look by engaging the shoulder 12 thereof. The lock-set position is shown in Fig. 5, and the position of the parts with the knuckle open in Fig. 6. When the ,lifting action is released, the lever 20 Wlll drop from the position into which it has been forced backwardly until the lug 16 strikes the part 15 on the locking block.

The lever is free to take this action under gravity because the lock is at this time suspended on the upper higher face portion 10 of the knuckle tail, thus leaving the lever free to swing under gravity. This is an important feature, because it avoids liability of the lever stopping aftera portion of this rearward swing which might lock-set the lock. As .the knuckle tail now moves rearwardly, the lock moves down from the upper face 10 of the knuckle tail, the tail swings through the recess in the lock and the looking block drops down to place. It will therefore be seen that the locking lever drops back to its normal relation with the look before the lock has dropped to its lowest position. The lock and the lock lift lever then both drop down to their final lowermost position after the knuckle tail has passed through theopening in the locking block.

Any desirablejform' of bottom operating mechanism may be employed for forcing the In the form shown, there is a bottom-operating lever 25, which is pivoted between lugs 26, depending below the pivot pin hole, the hub of the lever thusealso acting as a pivot pin support in case of breakage. At its bend, the lever is provided with a hole or eye 27, to receive the uncoupling lever 27, one hooked end of which is pivotally engaged with a lug 27 on the coupler head, while the other end may be engaged by the usual lifting chain, secured to a cross rod, not shown. The upwardly curved inner portion of the operating lever abuts against the lower outer end portion of the lever 17, to lift this lock lift lever.

In order to 5 limit the downward movement of the operatinglever 25, I preferably provide it with a side projection or lip 28, which, when the parts are assembled, is above an inwardly projecting lip 29, on one ofthe hinge lugs of the lever.

; Instead of pivoting the lock lift lever loosely on an axle, a shaft may be arranged to operate it; Thus, in Fig. 17, I have shown the shaft 18 as being lengthened, with its outer portion projecting through the side of the coupler head, and having an opcrating arm 30, which may beconneeted by a chain 31, to the uncoupling lever or'may be otherwise operated- In this case, the intermediate portion of the shaft is secured to the lever 17 by a spline connection 32, and the outer portion of the shaft which is preferably enlarged may beprovided with a groove 33, engaged on one side by a cotter or pin extending through avertical holeinside the coupler. prevent endwise movement of the shaft, while allowing its rotation. In this case, the rotation of the shaft will swing the operating lever 17, the action being the same as before. Instead of allowing the operating lever to merely abut against the lock lift le ver, I may provide them with a pivotal link connection 34:, as shown in Fig. 18.

The advantages of ,my invention result from relieving the pivot pin from a great part of the strain thereon, without departing from the usual M. C. B. lines. Also from the simple and effective lock and lockoperating mechanism, which provides for locking the lock, lock-lifting, lock-setting, and knuckle-throwing.

Many variations may be made in the form and arrangement of the parts without departing from my invention.
