Abstract
Abstract A device for pulling weeds. The device has a handle with a plurality of prongs projecting from one end of the handle. The prongs engage the weed and break up the ground surrounding the weed as the handle is rotated. The weed becomes entangled in the rotating prongs which are withdrawn from the ground to extract the weed.

Claim 1
Independent Claim
182 words
A weeder, comprising: a. a base; b. an elongated handle extending from the base, the longitudinal axis of the handle being normal to the plane of the base; c. a plurality of prongs extending from the base in opposed, parallel relation to the handle, the prongs being equally spaced radially from, and arcuately around the center point of the base; d. a hollow slidable sleeve disposed in surrounding, covering relation around the base and adjacent portion of the handle, the sleeve having an open end extending beyond the base in a direction towards the free ends of the prongs; e. a plate secured to the sleeve and sealing the open end of the sleeve, the plate having a plurality of holes for slidably receiving the prongs; and f. means for mounting the sleeve for limited reciprocating movement along the longitudinal axis of the handle, whereby the plate can be moved towards and away from the base to disengage weeds entangled on the prongs, said means including a dowel extending between the handle and sleeve and an elongated slot for receiving the dowel.
