  • Patent number: 5409281
    Abstract: A weed pulling apparatus has a tubular member and a handle. The end of the tubular member distally from the handle is inserted into the ground around a weed for forming a weed plug. A plunger rod is longitudinally disposed inside the tubular member and it is axially movable within the tubular member. A weed plug ejecting mechanism includes a lever pivotally mounted at the handle, a lock plate having an opening formed therein through which the plunger rod projects and a plunger head carried on the first end of the plunger rod. The lever and the lock plate cooperate such that, when the lever is pivoted, the lock plate forces the plunger rod downwardly in the tubular member and the plunger head ejects the weed plug from the tubular member.

  • Patent number: 4986588
    Abstract: A weed puller is disclosed having a tubular main body member in one end of which is mounted a piston that is spring-biased toward a released position adjacent the body one end. At its other end, the main body member is provided with a handle arrangement for displacing the piston to a retracted positon within the body member via a piston rod that extends longitudinally through the main body member and projects at its free end therefrom. A drive plate is incrementally displaced by a lever to incrementally displace the rod and the piston toward the retracted position, and a releasable locking plate locks the rod and the piston against return displacement toward the released position.
