JOI-IN WARNER AND JACOB -I. VGSBURGH, OF GALESBURG, MICHIGAN.

STUMP-MIA CHINE To all whom fit may concern:

Be it known that we, J oHN IVARNER and J. H. VosBUReH, of Galesburg', in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Machines for Extracting Stumps; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

In the annexed drawings making part of this specification A, represents the frame of the machine which is constructed in a strong and substantial manner and which is made of any suitable and convenient size.

lThis frame is supported upon axles B, B', and the axles upon the wheels C, C, C, C. The frame rests upon a bolster on the front axle as is usual in heavy wagons so that the machine may be readily turned about when changing its position.

At the rear of the frame A, is situated a frame L, which is provided upon its lower rlhis frame L, is so attached to the frame of the machine that it can be raised or lowered when the frame L, is lowered so`that the wheels (en) bear the weight of the rear of the machine. Said machine may be readily turned and adjusted to any desired position.

D, and E, represent two axles, which lie across the frame A, and have their bearings in the sides of saidL frame as is represented in the drawings. rThese two axles are provided with large pulleys or drums F, G.

K represents a `cord which is securedi at one end to the drum F, the other end of said cord passing out to the rear of the machine has a whiiiletree attached to it by means of which power is applied to the pulley or drum F H represents a chain one end of which is attached to the aXle D, while the `other end is secured to the pulley or drum G.

I, I, are chains which are secured at one end to the axle E, as is shown in Fig. 1, while their other ends unite and are secured to a chain M.

J, represents a ratchet wheel which is secured to one of the faces of pulley F. A suitable ratchet or p'awl is bolted to the frame of the machine, which catches into the teeth of this ratchet wheel J, and serves to station it at any desired point.

lVhen this machine is to be used, it is drawn into the field where the stumps are to be pulled up, and the chain M, is securely attached to the stump to be extracted. The other end of the machine is then made fast to a stump or tree, and power is applied to the whifiletree upon cord K. Vhen the cord K, draws, the pulley F, is made to revolve thus setting in motion the pulley G, by means of cord H, and also the stump by means of the chains I, I, which wind around the shaft or aXle E.

It will be seen, that by means of the system of compound leverage herein used, an immense power may be exerted upon the stump to be drawn, and that this machine may be employed with great efficiency.

Having thus fully described our invention what we claim as new and desire to secure by Letters Patent is.

1. rhe arrangement of the chains I, I, axles E, D, pulleys or drums G, F, chain I-I, and cord K, upon and in connection with the frame A, as and for the purpose herein fully set fort-h. y

2. In combination with the subject of the first' `claim the employment of the vertical frame L, when used as and for the purpose herein set forth.

In witness that we claim the foregoing we have hereunto set our hands in the presence of witnesses.
