v IMPovED PINCE-BAR.
The Schedle referred to in these Letters Patent and-naaking part of the same.
Be it known that I, PALMER SPALDING, ofthe city of Chicago, in the county `of'` Cook, and State of Illinoie, have invented a new and improved Pinch-Bar or l lever, in combination with fulcrum; andl do hereby declare that the following is` a full and exact descrip- ',tionof the construction and'operation of the same,
` reference being had to the "annexed drawings, makf ingga part of this specification.
y l construct my improved lever with its own `fulerum,
y which I call a pinch-bar, Vof the usualpsizes of ordinary evers in use, butfor running cars upontheir tracker y elsewhere, andfsafes, and other-heavy bodies@ prefer i y a har made .of wrought-iron or steel, five feet in length, Y
one and one-quarter inch square, tapering `toward 1, thenpper .end,1ike ordinary bars or levers now in` use. f- 1 At the lower end of thelever,1 make a pecnliarlyi shaped i, face, irnshing, as it were, a c am npou` the i. upper side of `the har; `and on the under side of the bar 1 1 make a heel' or fuloruni, pointed and notclvled, as
shown in thedrawi'ngs, and of steel, so that the point of ,the heel will he about three inches in a straight line from the points of the har.
The operation and utility of the bar, as improved by l me, are exemplified when applied to the moving of railroadoars upon their track, the notches biting the track and furnishing the point on which the lever turns, and
the face ofthe bar operating against the wheel.- 1mrnense. power, with my pinch-bar, by one man, may thus be exerted.
What I claim, and desire to secure by Letters Pat- Y ent is" A pinch-bar, having its'short arm with a fixed conveX face, and its heel or fulcrumformed with teeth, as and for the purposes hereinbefore set forth. y
l y PALMER SPALDING.
