91	Welded hand rake/fork tool with welded tine and method	US12321930	2009-01-27	US07644569B2	2010-01-12	Peter W. Lesche
A rake, pitchfork, or similar forked hand tool or tool head for mechanized machinery has welded tines. The tines each have a lower section located on the backbone of the tool head and a working section extending outwardly from the backbone. Each tine also has two lateral surfaces, two vertical surfaces and a transversely extending back edge surface therebetween. In one embodiment, welds extend the full length of one of the lateral surfaces, the full length of a vertical surface, the transverse length of the back edge surface and down the second vertical surface to the junction between the bottom of the vertical surface and the second lateral surface. Welds can also extend partially along the length of the second lateral surface for a distance not to exceed three quarters of its length. These tines have elongated fracture lines. The resulting tool is far less prone to breakage.
92	Welded hand rake/fork tool with welded tine and method	US12321930	2009-01-27	US20090211217A1	2009-08-27	Peter W. Lesche
A smoothing/sifting rake, fork, pitchfork, or similar forked hand tool or attachment or tool head for mechanized machinery has specially welded tines. The tines each have a lower section located on the backbone of the tool head and a working section extending outwardly from the backbone. Each tine also has two longitudinally extending lateral surfaces, two vertical surfaces and a transversely extending back edge surface therebetween. In one embodiment, welds extend the full longitudinal length of one of the lateral surfaces, the full length of a vertical surface, the transverse length of the back edge surface and down the second vertical surface to the junction between the bottom of the vertical surface and the second lateral surface. Welds can also extend partially along the longitudinal length of the second lateral surface for a distance not to exceed three quarters of its length. For heavy duty applications, welds are optionally applied to the back edge surface. The tool and machinery attachments with tines welded in this manner, in accordance with the unique method of welding, provides for increased strength of the tine to backbone juncture, thereby eliminating total separation of the tine from the backbone and preventing premature fracture of the tine along the leading edge of the backbone. The tines have elongated fracture lines and the resulting tool or attachment is much stronger and far less prone to breakage.
93	GARDENING TOOL	US12026171	2008-02-05	US20090194301A1	2009-08-06	Charles Grubb
The present invention provides an ergonomically shaped gardening hand tool comprising a base, a tool head extending from the base, and a handle extending from the base at an angle with respect to the tool head. The base may further comprise a pivot with a plurality of settings by which the user can adjust the angle of the handle with respect to the tool head. The tool head can be one of any kind of tool head used in gardening, including but not limited to a rake, hoe, pick, trowel, and the like. The handle may be padded for comfort and ergonomically shaped to accommodate the curvature of a gripping hand.
94	Welded hand rank/fork tool with welded tine and method	US12072525	2008-02-27	US20090084565A1	2009-04-02	Peter W. Lesche
A smoothing/sifting rake, fork, pitchfork, or similar forked hand tool or attachment or tool head for mechanized machinery has specially welded tines. The tines each have a lower section located on the backbone of the tool head and a working section extending outwardly from the backbone. Each tine also has two longitudinally extending lateral surfaces and a transversely extending back edge surface therebetween. In one embodiment, welds extend the full longitudinal length of one of the lateral surfaces, the full transverse length of the back edge surface, but only partially along the longitudinal length of the second lateral surface. For heavy duty applications, welds are not applied to the back edge surface. The tool and machinery attachments with tines welded in this manner, in accordance with the unique method of welding, provides for increased strength of the tine to backbone juncture, thereby eliminating total separation of the tine from the backbone and preventing premature fracture of the tine along the leading edge of the backbone. The tines have elongated fracture lines and the resulting tool or attachment is much stronger and far less prone to breakage.
95	Garden earth auger	US10013664	2001-12-13	US20020175005A1	2002-11-28	Hwei-Rung Chou
A garden earth auger operating by repeated twisting its handle is comprised of a drive mechanism at the center of the handle, a gear shaft erected inside the drive mechanism and extending downward to connect to a tooling feeder; a circular yoke inserted onto the gear shaft to control two mobile pawls on one side or both sides of the turning gear shaft to engage or disengage in or from the ratchet for the pawls to drive the ratchet for the tooling feeder to continue circulating for earth excavation in an effort saving fashion while the auger can be easily replaced with a fork or other forms of tooling head to excavate for a pit or scrap soil as desired.
96	Garden tool	US09780189	2001-02-08	US06467551B1	2002-10-22	Robert J. Washek
A garden tool for rejuvenating the soil of a garden includes a tool head and a handle pivotably mounted onto the tool head. The tool head includes a central hub and a plurality of tines which are integrally formed onto the outer periphery of the hub. Each tine extends radially outward from the outer periphery of the hub and includes an arm formed onto the hub, a sharpened tooth formed onto the free end of the arm and a pair of elongated, outwardly curved wings which are formed onto the tooth. The handle is adapted to be lockably disposed of at any angle from a horizontal position to a vertical position relative to the tool head.
97	Agricultural assembly having changeable tools	US09610029	2000-07-05	US06349776B1	2002-02-26	Shih Hao Hus
An agricultural includes a shaft slidably received in a tube, a foot rest rotatably engaged on the tube, and one or more tool members changeably secured to the tube. One of the tool members includes a plate secured to the tube, and a housing secured to the plate for engaging into the soil and having two casings. A board is slidably received in the housing and coupled to the shaft with couplers for disengaging the soil received in the housing. A lock device may detachably lock the shaft to the tube. The tool member may be a weed remover or a soil loosener.
98	Gardening implement having enhanced leverage	US693345	1996-08-06	US5937627A	1999-08-17	Janie McKittrick
A hand held garden tool configured to enhance downward force for digging and raking. The tool has a rod frame which extends from a working element attached to the tool at the front end of the tool to a brace located at the rear of the tool. The brace rests on the user's wrist or forearm, so that additional force is developed when the working element is urged downwardly into the ground. A handle depends from the frame at a point between the working element and the brace. Vertical orientation of the handle is more natural and comfortable than would be a horizontal orientation. The handle is provided with a molded grip for cooperating with a user's hand. The tool has a chuck for accepting diverse working heads, and preferably is provided with a plurality of diverse working heads. Exemplary working heads include rake, spade, and pry.
99	Hand garden tool	US15205	1998-01-29	US5887283A	1999-03-30	John R. Mackay
A hand worn garden tool is provided including a glove having a plurality of fingers. Next provided is a plurality of finger gardening claws each mounted to an associated one of the fingers. Each finger gardening claw has at least one hinged section mounted to the glove for pivoting with a joint of a user.
100	Garden tool having enhanced leverage	US614158	1996-03-08	US5813206A	1998-09-29	Janie McKittrick
A hand held garden rake configured to enhance downward force for digging and raking. The rake has a rod frame which extends from tines located at the front end of the rake to a brace located at the rear of the rake. The frame is bent to extend back towards the front end of the rake, at which point the frame terminates in an upwardly extending handle. The brace rests on the forearm, so that additional force is developed when the tines of the rake are urged downwardly into the ground. The vertical orientation of the handle is more natural and comfortable than would be a horizontal orientation. The handle is provided with a molded grip for cooperating with a user's hand. The brace has a resilient cushion for comfort when pressing downwardly on the tines.
