Application filed August 31, 1899. Serial No. 729,098. (No model.)
To 00% whom it may concern:
Be it known that I, WILLIAM BENNETT, a citizen of the United States,residingatBrockport, in the county of Elk and State of Pennsylvania, have invented certain new and useful Improvements in Stump-Pullers; andIdo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to apparatus for extracting stu mps, loosening boulders, and moving heavy objects requiring the expenditure of considerable force to start and lift them. The device is most especially designed for field use to clear the same of stumps of trees, roots, stones, and boulders.
The purpose of the invention is to provide a structure capable of easy transportation and movable from one stump, boulder, or objeet to another and which will be durable, convenient of operation, and effective in its workings.
The invention consists, essentially, of a stand or foldable structure to sit over the object to be moved, a floating lever, and a block and tackle connecting the long arm of the lever with the frame.
For a full description of the invention and the merits thereof,and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and the drawings hereto attached.
While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the apparatus as it appears when in operation. Fig. 2 is a front View. Fig. 3 is a side elevation. Fig. 4 is a detail View of the means for connecting the bars of the frame and forming a fulcrum for the lever. Fig. 5 is a sectional detail showing the manner of connecting the lower end of a bar to the'base-timber.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The framework structure or stand of the device is portable and of a folding character and comprises three bars 1, 2, and 8, which are connected at their upper ends in any substantial manner and diverge at their lower ends. One of the bars, as 1, is provided at its lower end with a base-timber 4, and the other bars 2 and 3 are connected at theirlower ends by a base-timber 5 common to-each. The base-timbers 4 and 5 prevent the lower ends of the several bars entering the ground to a great depth when the apparatus is in operation. While the upper ends of the bars comprising the structure may be connected in any desired and substantial way, it is preferred to unite them by means which hereinafter will be more particularly referred to in connection with the support for the floating lever 6. The lower ends of the bars are reduced and passed through openings formed in thebase-timbers, their projecting ends be ing pointed, as shown at 7, to enter the ground to a sufficient depth to prevent slipping of the base-timbers when the apparatus is set up for operation. Shoulders 8 are formed at the bases of the reduced ends of the bars and overlap the base-timbers and limit the downward movement of the bars with reference thereto.
The floating lever 6 has a fulcrum-support at one end suspended from the structure, and its opposite end is adapted to be connected by block and tackle with the upper end of the structure, preferably to the upper portion of the bar 1, which is projected above the pivot-fastening a suliicient distance for this rope or cable 11 is made fast to a pulley-block, as 9, and the opposite end portion passes un-' der a directing-pulley 12, applied to the basetimber 5 at about an intermediate point, the
drive or team being hitched to the outer end of the rope to apply power thereto when extracting a stump or loosening a boulder.
Companion rods 13 connect the pivotal end of the leverwith the upper end of theframe, and each is provided at its respective ends with an eye 14 and a bent terminal portion 15. The bent end 15 of one of the rods 13 passes through openings formed in coincident relation in the upper ends of the bars 1, 2, and 3 and pivotally connects them, and the projecting portion of the bent end receives the eye 14 of the other rod. The latter rod has its bent end passed through an opening in the inner end of the lever 6 and constitutes a fulcrum therefor, its projecting end receiving an eye of the first-mentioned rod. It will thus be seen that the two rods 13 are oppositely disposed-that is, the bent end of one is uppermost and the bent end of the other lowermost, the eye ends of the rods being similarly disposed, so as to receive the projecting end portions of the bent terminals. Cotter pins or keys 16 are applied to the projecting end portions 15 to retain the eyes ll in engagement therewith after the parts have been properlyassembled. Therods13aredisposed upon opposite sides of the lever and upper connected ends of the bars. Hence the strain is equalized upon the frame and lever and torsional strain is obviated.
A draft-chain 17 has connection at its upper end with the lever 6 and is provided at its lower end with means for engagement with the stump, root, boulder, or other object to be moved or lifted, said draft-chain being applied to the lever at a point between its fulcrum and point of application of power.
The apparatus is capable of being quickly dismembered, so as to be packed or stored in a small compass either for transportation or storage, and can be quickly set up when required for use. When it is required to extract a stump or loosen a boulder, the structure is placed over the object to be moved about, as illustrated in Fig. 1, and the lower end of the draft-rope 17 is hitched or otherwise connected to the object to be loosened. The outer end of the rope or cable 11 is hitched to the team, and when all is in readiness the draft is applied by urging the team forward, when the outer end of the lever 6 will be elevated and impart an upward pull upon'the' draft-rope 17 and stump or object to which said draft-rope is hitched and effect a loosening or lifting thereof. It will be observed that the lever 6 is free to move, thereby equalizing the strain upon its opposite end por tions, which is of material advantage. 4
Having thus described the invention, what is claimed as new is 1. In elevating apparatus of the character specified, a frame composed of a series of bars, a lever, companion rods having their opposite ends provided with respectively bent portions and eyes and oppositely disposed with their bent ends engaging with the said lever and bars and having the projecting portions of the bent ends receiving the corresponding eyes at the other end of the rod, substantially as set forth.
2. The herein-described apparatus consisting of upwardly-inclined bars having their lower ends reduced and formed with shoulders and pointed terminals, base-timbers ap* plied to the lower ends of the bars with the pointed extremities of the lever projecting to penetrate the surface of the ground, a floating lever, companion rods having their ends provided with respectively eyes and bent terminal portions, said rods being inversely disposed and having their bent terminal portions engaging with, respectively, the lever and converging ends of the frame-bars and serving as connecting means for the latter, the eye of one rod being engaged with the projecting portion of the bent terminal of the other rod and held thereon from accidental displacement, a block and tackle connecting the free end of the lever with the upper end of one of the frame-bars and adapted to have the power applied thereto, a direction-pulley applied to one of the base-timbers for the rope of the block and tackle, and a draft-rope applied to the floating lever and adapted to be connected with the stump or object to be moved, substantially as set forth.
In testimony whereof I aifix my signature in presence of two witnesses.
