.Letters Patent No. 82,932, lated October 13, 1868.'

IMPROVED STUMP-EXTRACTOR.

The Schedule referred to in these Letters vPatent and making part of the same.

To whom it may concerny Be it known that I, RUnUs B. Fnnn'rs, of Holland,

in the county of Ottawa, and State ofMichigal', have invented a new and useful Improvement in an Apparatus for Extracting Stumps and Lifting Heavy Weights; and l do declare that thefollowing is a true and accurate description' thereof, reference heilig had to the accompanying drawings, and to the letters of reference marked thereon, and being a part of this specification, in whichl Figure l is a perspective view, and

Figure 2 is a side elevation, partially in section, of the sheaved cani and its coni'iections'.

The obj ect of this invention is to construct a simple and cheap, but powerful apparatus for the purpose of extracting stumps 'from the ground, and for lifting heavy weights.

To accomplish this purpose, on two parallel sills, A, I erect four posts, B, forming a strongly-braced framework, pyralnidal in shape; each pair of posts heilig connected longitiulinally at the top by a tie-beam, C,

- surmouuting which are standards D, between which is suspended a pulley-block, E. F is asheavcd cam, rigidly secured to a shaft, G, journalled into the tieheams C, and operated by a lever, H, iirlnly bolted to the dat portion of the sheave F. A chain, I, is secured to the lever at its junction with the caln, around which, in a proper groove or sheave, it passes, and descendiu g to the ground, terminates in a proper hook, for convenience in seeming to stumps, 85o.

J is a rope, one end of which is secured to one endv of one of the sills A, and passing up througha sheave the team is attached. K a halyard, one end of which is secured to the lcver H, passingr through the sheaveblock F down to the ground, by means of which the lever H may be raised, and the chain slackened.

To operate this apparatus, we will suppose that a y stump to be extracted is under the cam and between the sills: Draw up the lever H with the halyard K, hook the chain securely around the body of or under the roots of the stump, attach a team to the end of the rope J, and start them forward, when a powelful strain will be exerted on the chainmI, and the work is done.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the lever H, sheave F, chain I, rope J, sheave-hlocks 3 and 4, sills A, post B, tie-beams C, standards' D, pulley E, and halyard K, when. conf structed, arranged, and operating substantially as described, and for the purposes set forth.
