' motive or similar railway vehicle.

' ler head in Whic Where a coupler isused on the end of a locomotive equipped with a pilot it is necessary to support the coupler some distance away from the pilot block, and under such circumstances it becomes infeasible to emloy the ordinary uncoupling .means. I

ave, therefore, invented animproved and simple uncoupling mechanism for usein connection with the locking pin of a con ler of the knuckle'type to raise the same. referably the coupler proper is pivoted toaforwardly projecting sup ort or draft member mounted on-the pilot lock. As the raisingmeans for the locking pin of the cou ler I employ a lifting lever actuated by suitable manually o erated means and since the coupler may shift laterally, bein ivoted, it 'is necessary to so mount this li ting lever that it will also turn with the coupler. The lifting lever may be ivoteddirectly'to the'cou l scase it also turns with t e coupler, or the lifting lever may be pivoted on-t with means which compel the lever and pivot pin to turn simu'ltaneousl with the shifting of the coupler. Under t ese conditions t is lifting lever is always in operative connection with thelocking pin-whereby the latter may be raised by lifting thelever. I On the. accompanying 'drawing'sal have illustrated desirableembodiments of my invention, and on all theviews of the drawings" parts throughout. g

I through its lateral flanges 11 to the pilot block or other sup ortt12. The outer or unsupported end 'of tlledraft member-1O is provided with a curved recess 13 adapted to receive the shank of the coupler, and to permit the same toturn on its pivot. A vertical pivot pin 14 passes downwardly through the outer end of member 10 and through recess -13, and is maintained in place by the collar 15 which rests on the upper surface of. the member 10 and the transverse cotter 1'6 which prevents the pivot in 14 from -rising.

The coupler 17 has the or inary knuckle 18,

knuckle pin 19 and a locking pin 20 provided with alongitudinal slot 21. he shank22 of the coupler fits in recess 13, and pin 14 passes throu h a round aperture through the shank where y a lateral shifting or turning of the coupler is permitted. On its top end pin 14 has two upstanding s aced apertured lugs or STEEL rouNnnrns, or

10 bolted at its rear end' ears 23 between whic is placed and towhich is pivoted a lifting lever 24, having at its free end, which projects within slot 21, an u standing proj ectlon 25 which in the elevate conditions of both the locking in andlifting lever strikes a stop 26 within s 0t 21 thereby limiting the upward movement-of the lifting lever. On the end of the locomotive or other vehicle and transversely thereto I mounta shaft 27 rotatable in one or more bearings 28 rising from. the 'top surface of the pilot block 12. .At its outer end this shaft has a handle 29 whereby it maybe turned, and at its inner end it is bent laterally to' provide an arm 30 which is connected by'means of a chain 31 with the lever 24 atthe point 32.. In order to compel'the lifting lever and pivot pin 14 to turn with the. coupler as the latter is moved laterally the to surface of the coupler head is longitudina ly slotted at 33 so as to provide .a

of the sides of the lever and compels the same and the pivot pin to turn in unison with the coupler whereby the lifting lever is always in operative connection Witbfthelbcking pin.

- From the illustration. of this invention and V, I

the foregoin description it will be apparent that to lift t e locking lever so as to permit v is applied thereto between the fulcrum and i the load, and that more power is required to the knuckle 18 to turnon its pin 19 andbe come uncoupled from the cooperating coup ler head, it is merely necessary to actuate or 'lift the handle 29 thereby turning the shaft 27, lifting arm 30, chain 31, lifting lever 24, and locking pin 20. The weights of the parts are such that when handle 29 is released, arm

It may be noted that the lifting lever 24 is a lever of the third order in which the power raise the lock with this form of lever than would be necessary to directly lift the lock. The pull on the chain 31 must also be greater than would be required provided the chain was pulled directly upwardly above the lift- Ihese disadvantages of this construction are overcome, however, by the construction of the operating shaft 27 and its arms 29 and 30. In order to lift the locking lever'20- suficiently to perform the uncoupling operation only a comparatively slight elevation of the point 32 of the lever is reqnired and for this reason the arm 30 may be made short. Since the arm 29 on the other hand is longer than the arm 30 the mechanical advantage secured by the long arm 29 overcomes the disadvantage of the form of lever 24.'

In the modification shown in Figs. 3 and 4 the coupler 35 is pivotally mounted 'on the support or draft bar 36 by means of a pivot pin or shaft 37 which passes through a portion of the draft bar 36 and through the 'ing' suitably apertu red to receive pin 37 Passing transversely through the upper ear 38 of the coupler and the upper end of the pivot pin 37 is a horizontal stud sh aft 39 upon which is'adapted to turn the spaced legs 40 and 41 of a bifurcated lifting lever 42 which projects into a slot of locking pin 20 in front of the center of gravity thereof as in the pre- 'vious instance. In order to prevent this pivot pin or rod 29 from becoming displaced it is provided at one end with a head 43 while through its other end passes a cotter pin 44.

Leg 41 of the bifurcated inner end .of-lifting lever 42 has an upstanding apertured lug 45 which is connected to a chain 46 the latter beingadapted to be operated, that is lifted and lowered, by any suitable mechanism such, for example, as the shaft-27 witlr it's arms 29 and 30 of Figs. 1 and 2.

It will be understood that the lever 42 is pivoted not only to the inner end of the coupler but also to the pivot pin 37 upon which the coupler is mounted. Owing to the rod 39 passing through the pivot pin the latter turns as the coupler is shifted laterally. It

is thus apparent that the outer end of lever 42 always projects into the slot of the locking pin and has, therefore, a constant operative connection with the pin.

Although I have described fully the. details of the various forms of my construction, to

those skilled in the art it will be apparent that the structures may be considerably 1nodified indetails without departurefrom my invention, and without sacrifice of any of its benefits or advantages.
