outset,
I minor objects in View my invention conof the end sill sists of the parts and combination of parts as will be hereinafter more 'fullyyset out.
In the drawing, Figure 1 is an elevation ofa car. with my invention attached. Fig. 2 1s a top plan view of the same. i i lrepresents the end "sill to which a plate 2is secured by any suitable means. The
plate 2 is provided with an undercut groove to slide in the 3 in one of its faces and with studs or fulcrum points 4 and said fulcrum points being disposed in ditfereut horizontal'planes.
6 is a plate having shoulders 7, said plate and shoulders being mounted and adapted undercut groove 3 of the plate 2. i
8 is a fulcrum stud integral with the plate 6 upon which the operating lever 9 is pivoted and secured. thereon by any suitable means. The operating lever 9 is provided with an arm 10 having an offset or clip 11 on its extreme end.
1:2 is a lever pivoted upon the stud 8 at one end and adapted to rest and be supported in the clip or offset 11. The extreme inner end of the lever 12 is adapted for engagement'with'the coupling pin or one of the links of a chain secured to the coupling pin as found most desirable. It will be noted that the lever 12 has a rearward extension 13 beyond the pivot stud 8 to a point beyond the fulcrum 5.
In operation if pressure is exerted downwardly upon the operating lever 9, the inher end of the lever 12 is elevated through the medium of the clip or offset 11' of the operating lever 9, thereby elevating the uncoupling pin. If the outer end of the, op'
erating lever 9 is .pulled upward, then the arm 10 of the lever 9 is caused to move downward until it 'coines'into contact with a fulcrum a; On continued upwardmove-x merit ot the outer end of the operating le- Speeifieation of Letters Patent.

said pivot pin,
Patented Mar. 8, 1910..
ver 9 the lever is then fulcrumed on the fulcrurn 4 whereby the pivot 8 with its plate 6 is caused to cut groove 3, which brings the rearward extension 13 of the lever 12 into contact with the fulcrum 5. A continued upward movementof the operating lever throws the extreme inner end of the lever 12 upward by reason of the fact that said lever 12 is now fulcrumed'on the fulcrum 5 and swings on thetpiivot 8 whereby the uncoupling is etec e slide upwardly in the under-- As changes may be made in the minor details of construction without departing from the spirit of my invention, I do not wish to be understood as limitinglmyselfto the de tails of construction shown.
Having thus described my invention what Iclaim is: p
1. A two-part uncoupling lever having a slidin .fulcrum.
12,. 11 .uncot1plinglever comprising two levers, a slidably mounted. shifting fulcrum and a fixed fulcrum for both levers; 4
3.- An uncoupling lever comprising a plate havin a dovetailed recess, studs on the face of sai plate on opposite sides of said recess and in different horizontal carried by said block, of a lever pivoted on one end of the lever being longer than the other, the shorter end being constructed to engage one of the studs on said plate, a lip formed on "the shorter end of the lever, a second lever pivoted to said pivot pin, the longer arm of said second lever resting in said lip and constructed to engage the locking pin of a coupler, the shorter arm-adapted to engage one of the studs on said plate.
4. An uncoupling lever comprising a Jlate, two fulcra fixed on said plate in difi erent horizontal planes, slidable fulcrum mounted on said plate, an operating lever pivotally mounted on said slidable fulcrum, an arm extending beyond the slidable fulcrum and integral with the operating lever, an uncoups ling lever pivotall v mounted at-a point near one end on the slidable fulcrum.
