UNITED STATES PATENT OFFICE,
FREDERIC PLANT, OF BRIOKSBURG, NEW JERSEY.
IMPROVEMENT IN STUMP-EXTRACTORS.
Specification formingr part of Letters Patent No. 145,966, dated December 30, 1873 application filed Aprn 11, 1871.
To all whom it may concern:
Be it known that I, FREDERIC PLANT, of Bricksburg, Ocean county, New Jersey, have invented certain Improvements in Stump-Extractors, of which the following is a specification:
The nature and objects of my invention consist in certain mechanical contrivances and improvements for the purpose of facilitating the extraction of stumps; also, rendering the stump-machine more portable.
Figure l is a side elevation. Fig. 2 is a transverse section through A to B. Fig. 3 is an additional elevation of the lifting motion, showing the position of levers, Src., when forefoot of machine is raised; Fig. 4, an elevation, showing the position of arms, &c., when the hind foot is raised for locomotion.
a a are the side standards; b, the crosshead; c and c', the feet; d d, Fig. 2, iron bearings supporting the shaft c, on which is made tight the spiral-grooved barrel f, and to which is attached one end of the rope or chain g, the other end of rope being carried over pulley h, under pulley z', and up to the cross-head b, and there held by the eyeboltj. 7c is a worm or endless screw sliding on the shaft l, gearing into and driving the wheel m, fixed on shaft e. On the shaft l, and at opposite end to the worm, is screwed the bevel-wheel n, gearing into and driven by the small bevelwheel o, fixed on the shaft p. q q are arms, movable on the bolt r. sis a forked rod, moving in the fixed bearings t t, and at the lower end spanning the wheel u. c is a bent arm, secured to both sides of the standard, pivoted on the bolt w. On the lower end of these arms the axle of the wheel oc runs, and at the upper end of these arms works the lever y on the pivots z.
I will now describe the mode of using the machine.
A small machine, suitable for extracting small stumps, is moved from place to place by lifting'up the hind foot, by means of the arms q q, till the wheel u takes a bearing on the ground; but with a large machine for extract ing large stumps it is necessary to use the lever y, by depressing which the front foot is raised a few inches from the ground, as shown in Fig. 3; and for extra heavy and strong machines, I also lift the hind foot by making the short end of the levers or arms q q depress the rod s, which, compressing the spiral spring t, and forcing the wheel u to the ground, raises the hind foot of the machine from the ground, and relieves the operators arms from a considerable portion of the weight. The machine is then moved to and placed over the stump. The arms q q are dropped, which permits the hind foot to again rest on the ground, and the lever y, being turned up, allows the forefoot also to settle down on the ground. The grappling-irons being next fixed to the stump, the winch is placed on the shaft e, the slack of the chain drawn taut, and, if a small or somewhat rotten stump, it may be drawn with this power; but when the stump is large or firmly fixed in the ground, I apply the second power by moving the winch to the worm-shaft l, and sliding the worm k intogear, which gives ample power for ordinary large stumps; but for very large stumps it is necessary to apply a still greater power, in which oase, I place the Winch on the shaft p, which again greatly increases the power. The worm la, when in gear, acting the part of a pawl and ratchet, allows the winding to cease, and the handle to be shifted without in the slightest degree lowering the stump.
What I claim as new in this machine is as follows:
l. The combination of the frame a a b, barrel f, chain g, screw k, wheel m, bevel-wheels u o, and shafts p Z o, substantially as and for the purpose herein specified.
2. In combination with the stump-extractor herein described, the wheel x, controlled by means of the bent lever or arm c and lever y, substantially as herein specified.
FREDERIC PLANT.
