Beit known that Ik, DAVID D.- Hens-N, of Weare, in the county fof Hillsborough and State of New lampshire, haveinveptcd a newjand-.use'ful Improvel ",men'tin Elevators, or; machines forraisingvheavy Vweights; and vIdo hereby declare that the following Vis afullandexact description thereof, referencebeing i had to the accompanying drawing and `to the letters- "of reference `thereon Y My lnventionfconsists in a novel constructionand arrangement of elevators, for raising `heavy weights.
In the accompanying drawingy Figure 1 is a front View of vmy improved stumppuller. p 'g Figure 2 is aside view of thegsanle.
.I n the constructionof my elevator, a suitable frame,`
I, is made,.or the working parts of the machine-may he mounted on an axle provided wit-l1 wheels, for mov*- inggthe machine' as desired.`
`'.llhe shaft A, upon which the chain is wound, Ahas "at one end a scre'whthread, and is `provided with a nut, so that the shaft will travel endwise when it is rotated, thus keeping thevlin'e of draft in the. same perpendicular line, while` the chain is prevented from I winding upon itself'.
` Attached to the chain are double-jointed hooks ou grapples H, for seizing the log, stone, railftrack, or' other objects. A I
`The shaft carries a ratchet-wheel, B, which isturned, with the shaft, by meansof the lever C and .-pawl D, and the dogG holds the ratchet andshaft while .the lever'is raised to take a new hold.
' :The pawl' `D is released' from the ratchet-wheel means of a'rod', D', and short lever L, and the dog is Vreleased by means of an elbow-lever, E, which bears vupon spring Fwhen rotated, thus lifting the dog and allowing the chain to unwind. Having thus'fully described my invention,
I c1aim-,. 'The above-described elevator, provided with the shaft A, having'end play, and operated by the lever C,V ratchet B, pawl D, rod D', and lever L,'combined and operated substantially in the manueland for the purposes set forth.
