STUM P-PULLER.

SPECIFICATION forming part of Letters Patent No` 361,943, dated April 26, 1887.

Application lilcd JanunryQ-l, 1837. Serial No. 225,295, (No model.)

T0 @ZZ whom it may concern:

Be it known that we, WILLIAM J oHN HART- RUP, WALTER HAETRUP, and GEORGE HART- RUP, all of Tidioute, in the county of Varren and State of Pennsylvania, have invented certain new and useful Improvements in Stump- Pullers; and we do hereby declare that the following is a full, clear, and eXact descrip- `tion of the invention, which will enable others skilled in theartto which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of our irnproved stump-puller, showing it in operation; and Fig. 2 is a vertical sectional view of the same.

Similar numerals of reference indicate corresponding parts in both the figures.

Our invention has relation to that class of stuinp-pullers in which two hooks are secured lo a lever and alternately engage a chain attached to the stump; and it consists inthe in1 proved construction of such a chain, and also the means by which it is suspended from asupport or derrick, as hereinafter more fully described and claimed.

In the accompanying drawings, the numerals 1 indicate three posts secured at their upper ends by means of abolt, 2, passing through the beveled ends, and a clevis or stirrup, 3, is secured with its perforated ends upon this bolt, and has adoubled bar, 4, supported from it by means of a suitable ring or link, 5, the ends ofthe said bar being of unequal length and formed into hooks 6 and 7. A chain is formed by a number of links, 8, having fiat side bars, 9, and round connecting-bars 10, passing through the adjoining ends of the side bars and connecting the links. One of these links, l1, is longer than the others, and is located at the end of the link 12, which is attached to the shorter hook in the top of the frame. A lover, 13, one end of which projects through said long link 11, is formed with a recess, 14, in the middle of its upper edge, and has a ilat bar, 15, pivoted in this recess upon a bolt, 16, the upper end of the bar being suspended by means of aring or'link, 17, from the long hook in the top of the frame. Alng hook, 18, and a shorter hook, 19, are pivoted with their bifurcated upper ends to the lever at both sides of the fulcrum, and the longer lever has a roller, 20, journaled between the bifurcated ends, while both the links are held toward each other by means of coiled springs 21,secured at their ends to the hooks. These hooks may alternately engage the cross-bars of the chain when the lever is rocked up and down, the chain passing under a sprocketpulley, 22, and having its end passed over the roller in the long hook, the end of the chain hanging down from the said roller.

The sprocket-pulley is journaledin a elevis or stirrup, 23, having an eye, 24, swiveled to its doubled lower end, and a chain, 25, is secured in this eye, and may be secured to the stump to be pulled.

It will thus be seen that when the frame is placed over a stump and the chain attached to the stump the hooks will alternately engage cross-bars of the chain, as the lever is rocked up and down, the springs drawing the hooks toward the chain, and,as the end of the chain is thus drawn upward and allowed to depend at the other side of the roller in the-long hook, the pulley will be raised and the stump with it, the other end of the chain being secured to the short hook of the frame.

It will be seen that the construction of all the parts of the machine is very simple, so that it may be manufactured at a compara tively small cost, and may be strong and durable, and if by accident or wear any portion of the machine should break it may be easily replaced or repaired.

The entire machine may be taken apart for transportation, and may easily be put together again, and the machine may be used for raish ing any heavy burden.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States 1. In astump-puller, the combination of a derrick having a doubled bar suspended from its top, having a hook at each end, a chain suspended by one end from one of said hooks, said chain consisting of a series of links, one of which is longer than the others, a lever pivotally suspended from the other of said hooks, one end of which passes through the long link of the chain, and two hooks pivotally secured IOO at one end to the lever and adapted to engage the chain with their other ends.

2. In a stump-puller, the combination of a derriok,a doubled bar suspended from its top, having a hook at each end, a chain suspended from one of said hooks, said chain consisting of a short link, zu long link, and a series of short links, said short link being suspended from one of the hooks in said doubled bar, a lever suspended from the other hook, one end of which passes through said longer link, two hooks suspended from said lever, the lower ends of which are adapted to engage with the series of shorter links in said chain.

3. In a stump-puller, the Combination of :1, derriek, 2L doubled bar suspended from its top having a hook at each end, one end of said bar being shorter than the other, a Chain snspended from the hook upon the shorter end of said doubled bar, having one of its links 2o longer than the other, a. lever suspended from -the longer end of said doubled bar, one end of t WILLIAM JOHN HARTRUP.
