CHAPTER VII. 



STUMP-PULLERS, DERRICKS AND SLINGS, 

 STUMP-PULLEKS. 



Figure 175 shows a very powerful machine for pulling 

 stumps. The woodwork is made of well-seasoned oak, 

 the winding shaft being eight inches in diameter and five 

 feet long. The lower block, in which it revolves, is six- 

 teen inches square and three inches- thick, having a hole 

 cut just large enough to receive the winding shaft, and is 

 fastened securely to the middle brace at the bottom. To 

 prevent the splitting of the winding shaft, two stout iron 

 bands are shrunk immediately above and below where the 

 lever or sweep is inserted. An old gear-wheel, with the 

 spokes knocked out, is fastened to the top cross-piece or 

 head-block, to receive the traveling ratchet attached to the 

 shaft. The upright pieces of the frame are of two by 

 eight inch oak, three and a half feet high ; the top cross- 

 piece or head-block two by sixteen inch oak, narrowing to 

 twelve inches at the ends, and three feet long. The frame 

 is set on runners four feet long, two by ten inch oak, so 

 the implement can be quickly moved from place to place ; 

 the entire frame is mortised together. The anchor is of 

 one-inch round iron, and attached as shown in the illus- 

 tration, and a strong iron pulley-block is used on the 

 opposite side. In pulling large stumps, a chain is more 

 reliable than a rope. A single horse furnishes the motive 

 power at the end of the lever or sweep, which is ten feet 

 long. 



Figure 176 shows a cheaper and lighter stump-puller. 



The only expense is for the chain, links of one and a half 



to two inch tough iron, or tough-tempered steel ; ring, 



ten to twelve inches in diameter, and the hook, all of
