Specification forming part of Letters Patent No. $0,478, dated November 3, 1863. A

Tocll whom it may concern Be it known that I, ISAAC HICKS, of Hartford, in the county of Washington and State ot' Wisconsin, have invented a new and improved machine for extracting stumps, elevating stone and other heavy bodies and conveying the same from place to place; and I do hereby declare that the following is a full, clear, and exact description of' the same, ret'- erence bein g had to the accompanying drawings, making part of this specification, in whichl Figure lis a transverse vertical section ot' the same, taken in the line x00, Fig. 2; Fig. 2, a front view of the same; Fig. 3, a detached view ofthe hook pertaining to the same.

Similar letters of reference indicate corresponding parts in the several iigures.

The object of this invention is to obtain a simple and efficient device by which stumps may be readily extracted from the earth, stones and other heavy bodies readily elevated, and the stumps, stones, or other bodies when raised moved from place to place with the greatest facility.

The invention consists in the employment or use of a bar, suspended from a Windlass, which is placed upon a frame mounted upon wheels in a peculiar manner, said bar being provided with a hook constructed in a novel Way and all arranged in such a manner as to effect the desired end.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it. v

A represents a framing, which is composed of two parallel bars, c a, connected by crossbars, b, and supported at a suitable height by inclined bars c, which are attached to bedpieces dd, the latter serving as a base for the machine. On the cross-bars b there is placed a shaft, B, having a pulley, G, at its center. This pulley and shaft form a windlass, and the shaft B has two ropes or chains, D D, attached to it-one at each side of the pulley C-and these ropes or chains pass around pulleys e e at the ends of a bar, E, and are attached at their outer ends to the end cross-bars, b, ofthe framing A, as shown atj'fin Fig. 2. On this bar E there is placed a metal clip or band, F, to which a ring, G,is suspended by a link,H, and to the ring G a hook, I, is attached by a link, g. The hook I is constructed of a series of plates h, connected by joints z', which may be formed by bending the ends of the plates It over links j. Other plans, however, may be devised for forming'these joints. The outer plate, h, of the hook hasits outer end made so as to form a point, and has a notch, k, at each side to receive hooks l lon the ring Gyas shown more particularly in Fig. 2. The ring G is cut or provided with an opening, m, to

admit of the hook being readily attached to and detached from the ring.

In the back end of each bed-piece d there is placed centrally7 a small wheel, n, and to the t'ront of each bed-piece there is attached a metal frame, J,each having two wheels, o, at its back end. These frames J may be constructed by bending a metal plate in V form, one part ot the plate being directly over the other,and the back end of the upper part being provided with journals p, which are fitted in eyes q, at tached to the bed-piece, the wheels o being attached to the back end of the lower part of the plate. By this arrangement it will be seen that when the outer parts of the frames J are shoved down, that the front ends of the bedpieces dd will be supported by the Wheels o andthe back ends supported by the wheels c, and when the frames J are shoved upward the bed-pieces d will rest upon the ground. Both ends of each bed-piece d are rounded or beveled at their under side so as to admit of this result. This will be fully understood by referring to Fig. 1, in which the bed-pieces d are shown resting upon the ground, in black, and shown supported by the wheels a o in red, outline.

The operation is as follows: Suppose, for instance, a stump is to be extracted. The operator detaches the hook I from the ring Gr and then places the point of the outer plate, h, of the hook into the earth by the side ofthe stump, and presses the same downward until it is entirely buried. The adjoining plateis then forced into the earth in like manner, and so on until the outer plate appears above the surface of the ground at the opposite side of the stump, for it will be understood that in consequence of thus forcing the plates h into the earth the former will take a curved path. The machine is then adjusted over the stump, if not previously placed there, and both ends of the hook I attached to the ring G, one end of the former being attached to the latter by placing the link q on the ring and the opposite end attached by fitting the hooks llin the notches kk. The windlass is then turned by the application of any convenient power to the pulley G of the shaft B, and the bar E is elevated in consequence of the ropes or chains D D being wound upon the shaft B, the hook I being valso raised 'and with it the stump. When the stump is being Vthus extracted, the

.frames J are shoved upward to admit of the raised from the earth or extracted therefrom, and when elevated conveyed to any desired spot with the greatestfacility.

The elevated stump or other body may be retained by means of any suitable catch or fastening applied to the windlass.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is- A The frames J, provided with wheels o, and attached,as shown,to one end of the bed-pieces dof the framingv A, in combination with the fixed wheels n at the opposite ends of the bedpiecesand with the hook I, composed of a lseries ot1 plates, h, connected by joints, as and for the purpose, specified. i
