UNITED STATES PATENT OFFICE,

OSCAR A. KLEITZ OF SIGOURNEY, IOlVA.

STUMP-PULLER;

SPECIFICATION forming part of Letters Patent No. 407,667, dated July 23, 1889.

Application filed April 26,1889. $erial No. 308,676. (No model.)

, following description and claims, when taken in connection with the annexed drawings, in which Figure 1 is a vertical sectional view of my improved stuinp-extractor, showing parts in elevation; and Fig. 2 is a plan view of the same.

Referring to the annexed drawings by letter,

A indicates the base-frame of my improved device, which is of cruciform configuration, and may be made of any suitable material.

B indicates an auxiliary cruciform frame which should be firmly secured to the baseframe, so as to strengthen the same.

0 indicates a spindle or hollow post, which should also be rigidly secured to and extend upwardly from said base-frame. This spindle or post 0 is adapted to afford in its top portion a seat for the bearing-block D,which is connected with the fulcrum end of the adjusting-lever, which will be presently explained.

D indicates the bearing-block, which is seated in top of spindle or post 0, and affords a bearing for the fulcrum end of adj ustinglever E, which is secured thereto by means of a pin or bolt F, which allows said lever both a vertical and rotary play to move in unison with the draft-beam and upper cylinder. This lever E is of the class known as levers of the third degree, the weight being applied between the fulcrum-point and the handle portion, and is suitably journaled in standards G, which are fixed to thedraft or hitch beam H at a point adjacent to the cylinder Y, and may be adjusted vertically by means of perforations d and a pin or bolt Z.

About midway between the point at which the weight is applied and handle portion of the lever E, I attach depending arm P, which is provided on its sides with oppositely-directed teeth Z), the functions of which are to hold the lever, when elevated or depressed, by engaging with pin 0, secured to the draftbeam, and fix the position of said lever with respect to said draft or hitch beam. Thus it will be seen that when it is desired to wind a cable upon the drum I the lever is depressed and held in that position by the upwardlyextending teeth on the bar or arm P engaging with pin 0 on the draft-beam; but when it is required to unwind or slacken the cable the lever E is elevated, and the teeth on the opposite side of the bar, engaging the said pin 0, hold the lever E in that position, thus allowing a free rotation of the drum I.

I indicates the winding-drum of my ma chine, which is provided with flanges or collars J, for the purpose of retaining the cable thereon.

L indicates a recess and M a perforation, both formed in the upper flange of the winding-drum, which is adapted for the attachment of the hauling-cable.

K indicates the clutch-face of the windingdrum, which is provided with any suittble number of uniform-inclined teeth, which are adapted to engage and operate in conjunction with the teeth of the clutch-face of upper cylinder, as will be now described.

Y indicates a cylinder or collar, which is provided on its under face with a series of inclined clutch-teeth N, of corresponding number and size with those of the windingdrum and adapted to operate in conjunction therewith. This cylinder Y is also provided with a radial arm 0, whereby an attachment is effected between said cylinder Y and draft beam H by means of bolts a.

(Better illustrated in Fig. 1 of the drawings.)

Q indicates a clevis, which is adapted to be attached to a stake or tree and hold the machine stationary when pressure is brought to bear upon the same, and it is also adapted for attaching a draft animal for transporting the extractor from place to place;

R in dicatesa singletree for the'attachment of the draft-animal while in operation.

By having the base-frame of a cruciform shape I provide a convenient means for securing or staking the device in position during operation, as it is obvious that each branch may have a vertical aperture through which a stake may be driven.

Having; described 7 my invention, what I claim is 1. In a stump-puller, the combination, with the cruciform base, of the hollow post arranged thereon, the toothed drum arranged on said post and adapted to receive a Windingrope, the cylinder Y, having an arm for the attachment of the hitch-beam and provided on its under side with a toothed face, the bearing-block arranged in the upper end of the hollow post and beveled, as shown, the hitch-beam secured to the arm of the upper drum-section, the standards secured to said beam, the adjusting-lever journaled in said standards and having one end connected with the bearing-block in the post, and the depending arm pivoted to the lever and having oppositely-directed teeth, and adapted to enaozeev gage a pin on the hitch-beam, substantially as specified.

2. In astump-puller, substantially as described, the combination, with the cylinder, of the hitch-beam secured thereto and hav ing a stud or pin, the adjusting-lever fulcrumed in standards rising from the hitchbeam and having one end journaled on a block arranged in the top of the hollow post, and the depending arm pivoted to the adj ustr ing-lever and having its opposite sides provided with oppositely-directed teeth and adapted to engage the stud or pin in the hitch-beam, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

OSCAR A. KLEITZ.
