Claims
- 1. A weed pulling apparatus for rooted vegetation, from the ground comprising:
- a normally vertically upright elongate handle defining a first leveraging arm terminating in a lower end;
- a ground engaging second leveraging arm attached at an inner end of said second leveraging arm to said lower end of said lower handle end and extending laterally outwardly from a first side of said handle at an angle substantially normal to said elongate handle;
- said second leveraging arm also defining a ground engaging fulcrum about which said first leveraging arm pivots;
- jaw pivot means mounted to said lower end of said handle on a second side opposite said first side of said lower handle end;
- said jaw pivot means defining a pivotal axis substantially perpendicular to the longitudinal axis of said handle and substantially parallel to said ground surface when said handle is in normal upright position;
- a weed clamp including at least one jaw;
- a clamping surface proximate said at least one jaw;
- said jaw mounted on said pivot means to pivot about said axis to close toward and proximate said clamping surface;
- said at least one jaw and clamping surface arranged and constructed to engage and clamp the stem of a weed or shrub against slippage whereby when the upper part of said handle is rocked about said fulcrum from upright position in the direction of said first side of said handle.
- 2. The combination of claim 1 and wherein said clamping surface comprises a second clamping jaw pivotally mounted about an axis parallel to the pivotal axis of said first jaw at spaced predetermined distance from the pivotal axis of said first jaw.
- 3. The combination of claim 2 and wherein each jaw is eccentrically shaped and defines an arcuate clamping surface;
- and wherein the clamping surfaces of said jaws can be forcibly cammed open from a closed position with said clamping surfaces in near proximity to each other to a spaced apart open position to receive and clamp the stem of a plant to be removed.
- 4. The combination of claim 3 and wherein the eccentrically shaped jaws are pivotally mounted so that gravitational forces normally bias said jaws toward their closed position when the tool is in upright position, and whereby a user can by forcing the arcuate clamping surfaces of the normally closed jaws against a plant stem can cause the stem to cam the jaws open sufficiently for the spring bias jaws to open and clamp against opposite sides of said plant stem to permit forceful pulling up on the stem without substantial vertical slippage of said stem.
- 5. The combination of claim 4 and wherein the clamping surface of each jaw defines transverse gear teeth type serrations for biting into opposite sides of a plant stem to minimize slippage of said stem to said jaws.
BACKGROUND OF THE INVENTION
