ROSWELL H. HALL, F BRANCHPORT, NEW YORK.

MACHINE FOR EXTRACTING STUMPS AND MOVING HEAVY BODIES.

Specicaton of Letters Patent No. 923, dated September 15, 1838.

To all whom 'it may concern.'

Be it known that I, RoswELL H.y HALL, of the village of Branchport, in the county of Gates and State of New York, have invented a new and Improved indlass and Machine for Extracting Stumps from the Ground and Moving other Heavy Bodies; and I do hereby dec-lare thatl the following is al full and exact description of the same, with reference to the annexed drawing thereof.

The machine consists of a substantial plank platform marked A,.in said drawing of convenient size placed upon two runners curved upward at each end, as represented in the drawing, and a perpendicular iron frame B. C. I). E. of properheight (about three feet high) securely fastened at B. and E. to the platform. Through the middle of the v. top or cross bar' C. D. of the frame, and perpendicular to and at the lower end pass- `ing through the platform is plaeled an illon cylinder onspindle F. Gr. `about tiree inc ies 1n diameter terminated at the top by a head with a hole through it of sufficient size to receive the leve-r H. I. which may be of wood and of any desirable length and size. In the spindle at J, and about three inches above the platform is inserted an iron pin about half an inch in diameter extending outward two or three inches. At `F. is another similar pin about three inches .from .x the frame. This machine is placed i-n the direct line between two stumps K. and L. or other bodies to be moved or between one immov- A- able body as K. and the body to be moved as L. in such manner that the runners will be parallel with the direct line between the two i points K. and L, and so as to move readily toward either point. Leable B...of convenient length fastened at th'"e'ds to the two pulleys M. and M. is made fast in the most convenient manner to the body K. and another lilreeroi;1ie...or.ca,ble .,d to 4.5 which is attached the pulley N. is in a similar manner made fast to the body L. The

rope O of prpper size and strength is then assed over tie ulleys M. N. and through the frame on efcli'side of the spindle, and the ends of this rope drawn moderately tight are tied or fastened together at P and made fast to the body L, one of the ropes which passes over the pulley N. is then bent near the spindle at J into a loop, and the loop passed over and made fast to the iron pin at J. The spindle is then turned (pressing the pins against the head of the loop) by hand power applied to the lever H, I, and by turning the spindle the ropes T and U forming the two sides of the loop just mentioned are wound around the spindle in an ascending spiral from both such ropes being drawn toward and wound around the spindle at the same time and by one and the same motion of the spindle. The power thus generated is increased by the intervention of the several pulleys M. N. and M. and as the ropes wind around the spindle the two bodies K. and L. are drawn towardeach other. If the above mentioned loop is passed over or made fast to the pin at F. as it may be at pleasure the ropes will wind around the spindle in a descending spiral form.

The machine may be used with only the one pulley N. in which case the rope O. instead of passing over the pulleys M. M. is fastened directly to `the body K. and is fastened to and wound upon the spindle as before. The spindle may be made of any desirable diameter orlength and the various parts of the machine of any size at the pleasure of the builder.

W'hat I claim as my invention and desire to-secure by Letters Patent is- The above described arrangements of the rope-s and p ulleysjn. combinationmwith the wmdam.
