ROBERT B. MONTGOMERY, OF MONTOUR, IOXVA.

STU M P-EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 356,693, dated January 25, 1887.

Application filed July 1, 1886. Serial No. 266.838. (No model.)

To all 2072,0711, it may concern.-

Be it known that 1, ROBERT E. MONTGOM- ERY, a citizen of the United States of America, residing at Montour, in the county of Tania and State of Iowa, have invented certain new and useful Improvements in Stump or Post Extractors, of which the following is a speciiication, reference being bad therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in stump or post extractors; and itconsists in the detail, construction, combination, and arrangement of the parts, substantially as hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of my invention. Fig. 2 is an end view. Fig. 3 is a top plan view. Figs. 4 and 5 are detail views thereof; and Fig. 6 is a view in perspective of my invention, showing the standards extended.

In carrying out my invention I provide an oblong platform or base, A, preferably of wood, to which are secured the horizontal plates a a of two supporting standards, B B, one of which plates, a, is bolted at or near its outer end to the top surface of the oblong platform or base A, and its other inner end is apertured for passage of a bolt, hereinafter referred to.

The horizontal plate a of the supportingstandard 13 is provided with two (or more) elongated slots or apertures, a a", for passage therethrough of suitable nutted bolts, c a, for adjusting the position of the said standard B. The bolt a is passed up through the aperture formed at or near the inner end of the horizontal plate a, and also through the elongated slot or aperture a", after which it is secured in position by means of a nut on said bolt, thereby adjusting, in connection with its fellow bolt, (4*, the position of the supporting-standard B. These standards project at right angles from the horizontal plates, and are each additionally supported in position by means of inclined braces b 71, secured at or near the upper outer side of each standard and at or near the outer ends of each horizontal plate a a. Each standard is provided with'inclined slots or openings b, extending from one side downwardly therein to about the center thereof.

0 is the operating-lever, which is constructed principally of wood, and on one end is providedon its upper surface witha sharp-pointed plate, 0, secured to said lever by any ordinary means, and near the outer end of said plate, immediatelyin rear of the sharp-pointed projection, is passed therethrough, and also through the lever, ahooked bolt, D, extending a short distance beyond the upper surface of said plate, the purpose of which will appear farther on. The lever has also applied on either side thereof, at or near said end, two hooked plates, E, the flat portion of which is secured directly against the sides of said lever by screws or other ordinary means, the purpose of which will soon appear. Said lever is also provided with a series of holes or up ertures for passage therethrough of a suitable bolt or pin, F, which serves as a fulcrum or pivot for said lever, the projecting ends of said bolt or pin being inserted in any two of the corresponding inclined slots or openings b of the standards B B.

In lieu of passing the bolt or pin F through the holes in the lever, the latter is provided with a plate, G, secured to its under side, and in connection with this form of construction I employ a collar, F, which is inserted on the forward end of the lever. This collar has corresponding apertures formed in the lower portion of its sides for insertion of the bolt or pin F, the latter being placed in any two of the apertures in the standards. The pin being thus inserted in the standards, the corrugated plate will rest thereon, and can be adjusted as may be desired by slightly moving said plate over its fulcrum pin or bolt.

in operation, a suitable chain (not shown) is secured around the upper end of the post or stake, as the case may be, and the looped portion is then secured to the projecting hooked bolt D, and the sharp-pointed projection is plunged or forced into the surface of the article to be raised, after which pressure is applied to the outer end of said lever, thus effecting the raising of the post or stake being acted upon. l-Vhen, as is often the case, the post or stake to be raised is decayed and the sharppointed projection cannot be securely inserted therein, the chain is dropped down on the post or stake as far as desirable and made fast thereto, and the two ends of the chain are hooked on the hooks of the plates E, the lever being elevated for that purpose, and by forcing downwardly on said lever, the sharppointed projection is forced into the post, and the post can thereby be raised from the ground.

The object of rendering adjustable one of the supporting-standards is that in the event of it being a pole of large proportions, a stronger and larger lever may be employed, the standard B being adjusted accordingly.

The before-referred-to plate G, secured to the under side of the lever,while serving the purpose stated, also serves as a brace or protector for the end of the lever where secured. Said plate is extended up and. secured to the outer end of thelever, and is then bent back onto the upper surface of said lever, and the pointed plate 0 is secured in position, resting on this bent portion of the plate G, so that the inner end of the pointed projection rests against the upwardly-extended portion of the said plate. It will be seen that the hooked bolt is also passed through the backwardly-bcnt portion of this plate G and through the lever, and again through the said plate, and is secured by ordinary means on the under outer side of said plate.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination ofthe base-block and a stationary and a laterally-adj nstable standard with the lever having a plate provided with pointed projections on its end and a pivoted fulcrum-pin, all substantially as described.

2. The combination, with the notched standards and the fulcrum-pin, of the lever having the plate provided with pointed projections and the hooked bolt extending through said plate, substantially as shown and described.

3. In a stump or post extractor, the combination, with the platform or base and the lever, of the slotted standards having horizontal plates, one of said standards being laterally adjustable, and the nutted bolts, substantially as shown and described.

In testimony whereof I afiix my signaturein presence of two Witnesses.
