JOHN A. KAUSSLER AND HORACE B. COOK, OF WHITE PIGEON,

MICHIGAN.

Letters Patent No. 94,217, dated August 31, 1869.

IMPRO'VED STUMP-EXTRACTOR.

The Schedule referred to in these Letters Patent and making p art of the sama.

To whom it may concern:

Be it known that we, JOHN A'. KAUssLEe and HORACE B. COOK, of White Pigeon, in the county of St. Joseph, and State of Michigan, have invented a new and useful Improvement in Stump and Grub-EX- tractors; and we do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and being a part of this specification.

Figure 1 is a perspective view of our invention.

Figure 2 is a detached View of the lever and swivel.

Figure 3 is a view' of the adjustable grapnel.,

Like letters refer to like parts in each ligure.

The nature of this'invention relates to an improved construction of an apparatus for extracting heavy stumps or comparativelyV lighter' grubs; and consists of a suitable frame, so` attached to a carriage that it may be brought into' use when required, or elevated upon the trucks for transportation; also in an adjustable lever, suspended by means of a proper swivel' to the top cross-bar of the frame, in such a mannerthat the fulcrum-point may be changed, thereby giving the operator the necessary leverage to do the required work; also in a suitable device for raising the outer end of the lever, when desired; also in a novel clamp for grasping grubs, when the apparatus is used;

for grubbing,. and in a new, novel, and'ingenious arrangement of all its various parts, as more fullyl hereinafter described.

A, in the drawing, represents a suitable frame, composed of the bottom plates a, upright posts b; cross-bar c, and braces fl, properly put together and secured.

To the upright posts bare secured the metallic straps B, in suoli a manner as to formloops or guides, within which the standards C have a vertical movef ment.

To the foot of these standards are secured, -upon proper axles or journals, the wheels D.

Journalled at each end, to these standards C, is the rock-shaft E, to which are secured the cams e.

A semi-rotation of this rock-shaft is obtained by means ot' the compound lever F, lwhich is properlyv fastened for that purpose to one of the upright posts b, and to the rock-shaft.'

This partial rotation lcompels the cams e to engage with and against the pins f, which are` driven into the inner faces of the upright po'sts b, thereby raising the wholeframefrom oti' the ground and upon the stand? ards and wheels, ready to be transported to any desired point.

'Suspended from the cross-bar c, by means of double swivel clevis G, is the lever H, provided, upon its under side, with a series of pins, g, or suitable notches,

'the stop in place.

lever, and heldin any desired position by the notches or pms t.

From this clevis is suspended a proper chain o r rope, J, the lower end of which is designed to be passed around a stump to be extracted from the ground.

Then the hookin the bottoin ofthe block j is secured to the chain near the stump,.and power being applied, by means of the rope h, the stump is lifted from out the ground.

When the fulcrum-point is changed from the centre to a point nearer one end of the lever, it becomes necessary t'o adopt some device to raise the longer arn of the lever. This is done by erecting upon and securing to the cross-bar c a proper standard, K, provided at its top with a sheave, over which runs the rope lc, l

which is secured to the longer arm of the lever in such a manner that it can easily be raised, when desired, b v pulling upon the rope It.

When the apparatus is designedlfor pulling small stumps or grubs, which vary in size, and still are so small 'that the chain J cannot conveniently be secured to them, a clamp, L, may b e attached to the chain in such a manner that the clamp may be passed around the grub.

This clamp. is constructed of a strap of iron, madev in the form shown in the drawings, and its upper edges provided with seri-ations or teeth l, and the clamp o r grapnelis secured to the chain by the triangular link m.

After this clamp has been placed around the grub, the stop n, provided with bail o, is 'placed on top of the grapneh lthe stop n being next the two, while the bail o engages with any of the series of teeth l, to'hold The book in the bottom of the block j is thensecured to the bail c, and the power applied as in pulling larger stumps.

The -grapnel or clamp, constructed `in the manner described, can be adjusted, by means of the teeth and stop, to tit any-sized grub.

- What we claim as our invention, and desire to secure by Letters Patent, is-

l. The vclamp L, when constructed and operating substantially as and for the purposes described. l

2. The rock-shaft E, cams c, compound lever F, and

pins f, or their lequivalents, in connection with the constructed, and operating substantially as and for the frame A, standards O, and wheelsI D, when arranged purposes herein set forth and shown.

and operating substantially as and for the purposes J. A. KAUSSLER. herein speeiied. H. B. COOK.

3. The arrangement ofthe parts A, B, C, D, E, F, Witnesses: G, H, I, J, K, L, a, b, c, d,- e, j; g, h, z', j, k, l, m, n, JAS. I. DAY, and o, or their known equivalents, when combined, H. F. EBERTS.
