HENRY PERRY READING, OF EUREKA SPRINGS, ARKANSAS.

STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 275,855, dated April 17,1883.

Application filed March 3,1883.

To all whom it may concern:

Be it known that I,HENRY P. READING, a citizen of the United States, residing at Eureka Springs, in the county ot'Garroll and State of Arkansas, have invented a new and useful Stump-Puller,of which thefollowing is a specification, reference being had to the accompanying drawings.

This invention relates to machines for pulling stumps, raising or lifting rocks and other heavy weights, and thclike; and it consistsin certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view of my improved machine. Fig. 2 is alongitudiual vertical sectional view, and Fig. 3 is a horizontal sectional view.

The same letters refer to the same parts in all the figures.

A in the drawings represents a suitable frame, thelegs of which, BB, are mounted upon runners, in order that the device may be easily transported from place to place. The sides of the frame have boxes or bearingsO fora transverse shaft, D. upon which is mounted a gear or cog wheel, E. A chain, F, is also attached to the shaft D, and capable of being wound upon the latter.

G is a bracket projecting upwardly from the frame and having bearingsfor a vertical shaft, H, carrying a worm, I, which engages and operates the cog-wheel E. The inner side of the bracket forms a recess, which is provided with diagonal grooves J J, which receive the threads of the worm I, which is thus braced and strengthened and enabled to withstand the pressure of the cog-wheel E without causing the shaft upon which it is mounted to sag. A sweep or lever, L, by which the device is operated, is attached to the upper end of the shaft H.

(No model.)

-wound upon the shaft D. This device is exeeedingly simple and powerful,and being simply constructed it will not easily break or get out of order. This is also greatly due to the worm being braced in the grooves J of the bracket G. The device being mounted upon runners, as described, may be readily moved from place to place.

I claim and desire to secure by Letters Patent of the United States 1. In a stump-puller, the combination of-a suitable frame mounted upon runners, a transverse shal't having a cog-wheel, a chain attached-to the said shaft, a bracketprojecting upwardly from the frame, and a vertical shalt journaled to said bracket and having a worm engaging the cog-wheel, and provided with an operating sweep or lever, as set forth.

2. In a stump-puller, the combination of a suitable frame, a transverse shaft having a cogwheel, a chain attached tosaid shaft, a bracket projecting upwardly from the frame and having diagonal grooves, and a vertical shaft having a worm engaging the cog-wheel, and having its threads fitted in the said diagonal grooves, whereby the device is braced during operation, as set forth.

In testimony that Iclaim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
