JOHN B. HEARD, OF BOWLING GREEN, KENTUCKY.
STUMP -EXTRACTOR.
SPECIFICATION forming part of Letters Patent No. 331,054, dated November 24:, 1885,
(No model.)
To all whom it may concern.-
Be it known that I, JOHN B. HEARD, of Bowling Green, in the county of WVarren and State of Kentucky, have invented certain new and useful Improvements in Stump-Extractors; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
My invention relates to stump-extractors; and its objects are more fully delineated in the claims. I attain these ends by the means shown in the accompanying drawings, in which- 7 Figure 1 is'a side elevation of a wheeled frame having my improvements in position, showing their relative location and the manner of their operation. Fig. 2 is a front view thereof. Fig. 3 shows a modification of the grasping device. Fig. 4 is an enlarged detail View of the cutter, and Fig. 5 is a modification of the same.
The operating-lever A is adj ustably secured by asaddle, 0, having prongs O, to a curved frame, D, rigidly connected to the axle E, and joined to it are the upper toggle-arms, B B, which are pivoted to toggle-arms B B. The pivotal pin that connects the arms B B serves also as a means of attaching an adjustinga-rm, F, which is provided with teeth, F, that engage the axle E. The lever A being rigidly affixed to the frame D, and the latter similarly. connected to the axle, the axle subserves the function of a fulcrum for the lever A, besides its normal purpose of supporting the wheels H. The terminal portions of the toggle-arms B B are bent to form the cut ting-jaws G. These jaws open upon contact with the ground when the lever A is raised.
I is a frame secured to the axle E, to guide the regulating-lever F and to prevent its displacement.
In Fig. 3 is represented a modification of the toggle-arms. A saddle, J, affords means for attaching the rods K K, which'are connected to the grasping-levers K K, that have enlarged terminations L, to hold the obstruction more effectively. Fig. 5 shows a front View of this modification.
It will be understood that by moving the lever F forward or backward the angle of the cutting or grasping jaws is varied and an increased or diminished leverage is obtained.
Having thus fully described my improvements, what I claim, and desire to secure by Letters Patent of the United States, is-
1. The operatinglever A, secured on a wheeled frame, and the toothed adjusting-arm F, in combination with the axle E and the cutting device, substantially as shown.
2. The lever A, cap 0, having prongs O, curved standard D, and toothed arm F, in combination with the grasping device, sub stantially as shown.
3. The lever A, having hooks A, the cap my own I affix my signature in presence of two witnesses.
JOHN B. HEARD.
