WILSON'S PATENT STUMP A eS A i? ie i ne Sex . MANUFACTURED AND FOR SALE BY The Montague lron Works Co., MONTAGUE, MICH. Wor. Per, A SIMPLE AND EFFECTIVE STUMP PULLER. The tripod frame of this stump puller has two of itslegs provided with wheels, to facilitate moving it about, and to the third leg is swiveled a shoe, the head block at the top being preferably of metal, and having a conical open- ing, a half round washer resting on the block above the opening. The improvement has been patented by Mr. James D, Wilson, of Montague, Mich. Secured in any suitable way to the stump is a lifting shaft at whose up per end is a cap, the shaft having an exterior thread, preferably of two and a quarter inch pitch, and an adjustable Clutch on the shaft, below the head block, is adapted for locking engagement with the lower end of a hollow shaft through which the lifting shaft passes. The interior of the hollow shaft has a thread engaging that of the aad shaft, and the hollow shaft has a flange at its upper end and an exterior thread, preferably of four and a half inc pitch, the hollow and the lifting shafts being shown in their normal position in Fig. 1, A nut resting on the washer receives the exterior thread of the hollow shaft, the shape of the washer and of the head block permitting the lifting shaft to be somewhat inclined without becoming cramped. Arms projecting from the nut are secured to a lever or sweep to which a draught animal is attached, the lifting shaft moving up at a speed corresponding to.the pitch of Ps screw thread, as the sweep is carried around, but when the clutch on the lifting shaft engages with the hollow - shaft the latter is also carried up with the main sha‘t, at a correspondingly greater speed, owing to its coarser pitch, the stump then being raised four and one half inches at each revolution of the sweep. In Fig. 2the lifting shaft is shown drawn up toa connection with the auxiliary shaft, and in Fig, 3 the two shafts are showa elevated together. As will be seen, the stump is first started and slowly drawn up by the main shaft, and is afterward raised more rapid- ly by the coarser thread on the auxiliary shaft.—Screntific American. Will pull the largest stumps without digging or chopping. The price of all iron-work, including chains, is $125.00 delivere‘ on car or boat, Montague, Muskegon Co., Mich., and we furnish a blue print from which to make the wood work. ‘This machine has all of the advantages of the old screw power besides the advantage of the quick hoist for lifting the stump out of the hole, and will accomplish twenty-five per cent. more work than the ordinary stump machine.
