Letters Patent No. 109,015, vvdated November 8, 1870.

IMPROVEMENT IN MACHINE-SFOR EXTRACTING iSTUMPS.

The Schedule referred'to in these Letters Patent and making part of the same. l

To all 'whom it may concern.:

Be it known that I, J AMES A. JENKINS, of Clarksville, in the county of Pike and 'State of Missouri, have invented certain new and useful Improvements ofMachines' for Ext-ricating Stnmps, 815e.; and -I do hereby declare that the following is a full, clear, and

exact description thereof, reference being had to thc accompanylng drawing making part of this specifi-- cation, in whichparts in the several figures.

This invention relates to certain improi-'emeuts on, that class of machines for extracting stumps, trees, stones, 85e., from the ground, wherein the 'pewer is' applied to and sustained by a frame which is mounted upon wheels so as to render it portable, which wheels .v

are detachable when it is desired to operate the machine, as will be hereinafterexplained.

Ihe following description, when taken in connection with the accompanying drawing, will enable others skilled in the art to understand its construction and operation.

In the accompanying drawing- A represents" the frame of the machine, whiehis pyramidal, inclined forward, and Substantially erected vupon two strong sills or sled-runners A' A', which converge toward the frontend of the machine.

' The two upright front'portions of thc frame are connected together by a strong horizontal beam, a', andin rear ot this beam the base of the frame is sustained against lateral separation by means cfa transverse rod, 1. Y Y

llrom the front uprights of frame A project two beams, B B, which are strongly braced by straps a, and which sustain the front cud of the frame upon the bolster C of au axle, C1, of two transporting-wheels, C2 C2.

Io the axle C the stiff draft-pole C3 is secured.

'.Lhc chain c connects the frame of the machine to theaxle of the' front wheels, and itlmay'be'disco'nnected from said axle by removing the king-bolt I).

The pins' d d, which pass down through Ithe forward ends of the projecting beams B B, in front of the bolster C, also connect the frame to the front truck.

The rear wheels D2 D2 are applied to an axle, D, to which levers D D1 Dl are securely fastened.

lhefrcar ends of levers Dl Dl are provided with hooks c e, which are received by staples on the rear standards of frame A, as shown iniig. l, thereby se- 'c'uring the rear ends to the frame.

lhe front ends of these levers are held by means of' .loops j drawn back over them, as shown in gs. l

and 6.

To detach the wheels D2 y D2 from the frame the loopsj are pressed forward, and the hooks e removed from their staples; this allows thc rcar part of the machine to rest on the ground, as shown in fig. 2.

Across the top of frame A, and supported by j0ur` nal-boxes on the top longitudinalbcalns of this frame, two shafts, q g', are arranged, the ends of which shafts have heads on them that adapt the shafts to serve as braces for resisting outward pressure.

The front shaft g has a large flanged pulley, E, and

a drum, f, keyed on it,.and the rear shaft g' has a langed-pnlley, 1, and a drum, f', keyed on it.

Around pulley h is carried a draftrope, s, and around the drum f is passed a rope or chain, t', which latter is carried around the wheel E.

Around the drum f passes a rope or chain, h, which has a loop formed on its pendent end, for vreceiving a hook on a chain, It, shown in fig. 2.

In conjunction with the machine above' described I employ a .very strong lever', L, constructed with .a pointed end, n', a notched end,'n, a staple, t, and, it"

desired,' with two transporting-wheels. W, as shown in gs. 3 and 4. l f

I also employ, attached to the chain k, pivoted hooked-levers or grapple-hooks I, shown in figs.'2 and 5.

l (peration.

The machine is moved up to a stump or tree, as shown 'in g. 2,-and the grapple-hooks l applied to the stump'so as to hold rmly. The lever Lis then adjusted oveigthc chain 71', with the pointedV end '1a/ against the stump, and the rear forked end n receiving the chain. The staple t is then passed through one of the links of the chain, and a keydriven through the staplcbelow such link.

One or more animals are then hitched to the draft4 rope s and made to pull on this rope, at the same time to walk away from the machine, which will unwind the rope s from its pulley F, wind up the .rope t on drum f, and wind up rope h on drum f', thus lifting the free end of leverIr, and tearing the stump out 'ot'4 the ground, or loosening it so that its roots can be' readily severed.

It will be s ecn that the two pulleys E F, and vtheir drums connected as described, afford means wherebv tremendous force can be applied to the lever L, the fulcrum of which being at P, also affords great lever age in extracting stumps.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. The wheels :D2 applied-:to an axle or bar D, which' has seouredto it levers D, in combination with the fastenings e j, substantially as described.

' 2. The' lever L, with or without wheels W, construeted with a pointed end, fn', a forked end, n, and a staple, t, adapted for use substantially as described.

3. The combination and arrangement of the lever L, chain 7c, and grapple-hooks P, in the manner and for the purpose herein described.
