Letters Patent o. 106,926, dated August 30, 1870.
IMPROVEMENT IN STUMP-EXTRACTOR.
T'he Schedule referred to in these Letters Patent and making part of the same.
To allachom it may concern :v
Bc it known that I, ENOCH FARNswoaTH, of Sabbath Rest,- in the county of Blair and State of Penn# The object of this invention is to provide a stump-- extractor, which shall be effective in its operations, and simple and light in its construction, whereby it may be easily adjusted from place to place while at work; and to this end,
My invention consists in the construction, combination, and arrangement of the parts composing the same, as will be hereinafter specitically designated and set fort-h in the description and claim which follows.
To enable others to make and use the same, I will proceed to describe its construction and operation.
1n the annexed drawing forming a part of this specitication- A A A represent the parts which form the frame- |work of my device, braced by rods e a, and resting upon saucer-shaped plates. rlhe parts A A have a loop or yoke at their upper ends, through which the part A passes, where it is secured by a holt.' Each of' the parts A A A has a hook or eye near its lowerend, to which the power can be attached which moves themachine from place to place. It will be seen that the strain in moving need not, in this device, always be applied at the same point, whereas in others 'the power or strain must, if either be necessary,always be applied at the saine point, otherwise such strain.
would injure the machine. l
B'is a spool 0r pulley, fixed, in a permanent manner, upon the screw C, which plays through a threaded boss, D, suspended, by a rod, d, from the frame, 'as clearly shown inthe drawing.. The chain is attached to the screw, at its lower end, by a' link, which forms, with it, `a swivel joint. As the ropef'is drawn from the pulley the screw rises, carrying with it the stump., This extractor can be as etfectually applied upon a hill-side as upon an even surface; for this purpose it is only necessary to shorten the length ofthe part A by passing it through the yoke such a' distance as the degree of inclination ofl the ground may require.
Having thus described my invention,
What I claim, and desire to secure by Letters Patent of the UnitedStates, is-
A stumpextractor, consisting of the partsA A A', bars a u, rod (l, boss D, screw O, and pulley B, when said part-s are arranged' to operate substantially as shown and described, and for thepurpose set forth.
In testimonywhereof I have hereunto subscribed my name to this specification in the presence of twoattesting witnesses this 30th day of July, A. D. 1870.
