| 121 | Weed extracting device | US10924530 | 2004-08-23 | US07059421B2 | 2006-06-13 | Ronald E. Gray |
| A weed extraction tool is disclosed, comprising an elongated handle, a prong assembly, and a step assembly. The prong assembly includes a rod having a plurality of prongs attached at a lower end thereof and a pivot pin holder near its center. The step assembly comprises a flat step portion at one end, a plurality of fingers at another end, and two sides near the center of and under the step assembly. An opening is formed in the top side proximate its center, and each side includes a side opening. The rod of the prong assembly is inserted through the opening in the top side of the step assembly such that a pivot pin may be inserted through one side of the step assembly, through the pivot pin holder, and through the other side of the step assembly, so as to pivotably fix the prong assembly to the step assembly. As such, the opening of the top side of the step assembly is sufficient only to allow the step assembly to pivot between closed and open positions with respect to the prong assembly. In the open position the user may step on the step assembly to burry the prongs into a portion of ground adjacent to a weed. Then, while the handle is pulled towards the user, pivoting the step assembly around its contact point with the ground, the step assembly is forced into its closed position with respect to the prong assembly, the fingers pressing the weed against the prongs so as to firmly hold the weed therebetween while the handle is pulled towards the user to fully remove the weed from the ground. | ||||||

| A weeder includes a longitudinal shaft having a predetermined length and a longitudinal bore, a chuck mechanism provided at a lower end portion of the longitudinal shaft for pinching and pulling out weeds in the ground, the chuck mechanism including first and second pinching members for pinching the weeds therebetween, a first remover member combined with the chuck mechanism for forcedly removing the weeds and/or mud from the first pinching member, a second remover member combined with the chuck mechanism for forcedly removing the weeds and/or mud from the second pinching member, an operating lever mechanism provided on an axis of the longitudinal shaft for actuating the first and second pinching members and the first and second remover members, and a towing wire inserted and extending within the longitudinal bore of the longitudinal shaft, and coupling the chuck mechanism and the operating lever mechanism. | ||||||
| 123 | Weed-gripping pry tool | US10245544 | 2002-09-16 | US06698526B1 | 2004-03-02 | Jon Aril Mathisen |
| A tool, having a handle attached to a gripping structure, for ergonomically pulling weeds, including the bulk of their root systems, or other protruding shafts from the ground. The gripping structure has at least one tong that rotates from pressure against the surface of the ground. The rotation of the tong or tongs causes a gripping surface at the end of a tong to compress towards a mated gripping surface, forming a jaw. When operating the tool, the two gripping surfaces sandwich the weed-stalk to be extracted. This gripping structure works automatically with pressure against the surface, so unnecessary steps are eliminated in engaging or disengaging the tool. The handle is a lever arm pivoting the entire gripping structure, this forces whatever is held in the jaw away from the surface. | ||||||

The bit assembly has an open position and a closed position, and moves between the open position and the closed position in response to movement of the foot piece with respect to the shaft. At least two opposed spikes are spaced apart from a plane bisecting an angle between the at least two opposed spikes in the open position. A part of each of the at least two opposed spikes intersects the plane in the closed position. | ||||||
| 127 | Weed removal tool | US179303 | 1994-01-10 | US5456449A | 1995-10-10 | Francis P. Smith |
| A weed removal tool having a pair of upright elongated handles pivotally attached to each other near their lower ends, with protruding tapered tines extending axially from the lower ends of the handles. The tool is operated by plunging the tines into the ground on opposite sides of a weed, and separating the handles to compress the weed between the tines. A fulcrum block attached to one of the handles near the tines provides leverage for extracting the weed upon lateral tilting of the handles to force the block into the ground. The weed may then be lifted freely from the ground. | ||||||

| 130 | Weed puller | US851959 | 1986-04-14 | US4673165A | 1987-06-16 | Ralph F. Nelson; Donald S. Stephen |
| A weed puller is provided which comprises a handle to which are separately attached two (2) rotating, weed grasping prongs. The lower, or ground penetrating, portion of each prong is offset from the top portion thereof, so that when the prongs are rotated about their individual separate vertical axes at the handle, the lower portions of the prongs approach each other in parallel orientation so as to grasp the weed and its roots with essentially evenly applied pressure. The prong rotation is achieved through outward movement of upper ends of the prongs in camming slots formed in a camming member. Such movement is created by pivoting the handle of the weed puller, with the prongs inserted in the ground astraddle the weed, toward an outwardly extending lever member which is rotatingly attached along a horizontal axis at the lower end of the handle, and is rigidly connected to or an extension of the camming member. Continued pivoting of the handle leverages the grasped weed from the ground. An enlarged lever end may be used to provide a broader pivot base and, by its weight, to bias the prongs to maximum separation prior to insertion into the ground. | ||||||
| 131 | Weed puller and ejector | US69836 | 1979-08-27 | US4281866A | 1981-08-04 | James E. Atcheson |
| A metal strap having a pedal, fulcrum and weed pulling trowel is attached to the bottom of an elongated handle. The trowel is bifurcated and notched so it may be forced into the ground by a foot on the pedal and the weed root caught within the slot and pried from the ground by the fulcrum. The weed is ejected from the slot by moving a blade in the slot downward against spring action. In one embodiment the tines of the trowel are twisted on each side of the slot. | ||||||

| 133 | Weed puller | US44141474 | 1974-02-11 | US3918757A | 1975-11-11 | HUBER FRANK J |
| A weed puller having a shaft, a pair of raking prongs parallely disposed at one end of said shaft, and a weed grasping plate which is moveably disposed on said shaft to be received in contact with said raking prongs in a first position, said plate being actuated by a biased linkage mechanism adjacent the upper holding portion of the shaft. The inner edges of the raking prongs are flat and receive the plate flushly, thus providing for positive gripping action upon a weed that is disposed against the prongs. This allows for a positive grip of the weed body to allow the weed to be pulled without tearing the weed so that the roots are pulled during the weed pulling operation.
