| 243 | Post hole digger | US422080 | 1989-10-16 | US4986373A | 1991-01-22 | Guy Charland; Robert Beaudoin |
| A post hole digger and a method of implanting a post in the ground. A boring implement having a piercing free end and also having an attachment flange is secured to an end portion of a post to be implanted in the ground. The implement has a tapered body section with a projecting serrated edge on opposed sides thereof. The serrated edges extend angularly from a common longitudinal plane and in opposed angular directions. A pipe section is secured to the implement and a garden hose is connected thereto whereby to direct a stream of water in the direction of said piercing free end whereby axial rotation and counter-rotation of said post causes the implement to bore into the ground to cause said post to descend in a bore hole. After the post is implanted the garden hose is disconnected from the pipe section by applying a pulling force on the hose. | ||||||
| 244 | Soil coring device with a core ejector mechanism | US346916 | 1989-05-03 | US4884638A | 1989-12-05 | Michael R. Hoffman |
| A soil coring device with a core ejector mechanism that has a cylindrical cutting tube with two (2) 180 degree opposed tee slots that serve as a guide for an ejection plate, affixed to a cylindrical cutting tube is a tube with a vertically oriented slot attached perpendicularly thereto is a handle to which is affixed a bubble level. Located on the tube is a threaded locking knob that extends through the slot and communicates with a short presetting locking cylinder. Also located on the tube is a threaded locking hand knob that extends through the slot and communicates with a cylindrical rod to which a tamping plate is permenently attached. In operation, the soil coring device handle is rotated causing the cylindrical cutting tube to enter the soil to the predetermined depth, that has been preset by tightening the threaded locking knob into the short presetting locking cylinder, until ejection plate makes contact with the surface. The cylindrical cutting tube is removed from the hole, is then placed into the existing hole on the green, the threaded locking hand knob is released, both feet are placed on opposite sides of the cylindrical cutting tube and positioned on top of the ejection plate, the handle is pulled upwards ejecting the core into the hole. Then the tamping plate is displaced 2"-3" beyond the end of the cylindrical cutting tube, the core is then tamped with a tamping plate to achieve a level surface. | ||||||
| 245 | Funnel hole ice auger | US182875 | 1988-04-18 | US4819744A | 1989-04-11 | Ty J. Caswell |
| An ice auger includes a pair of ice boring blades fixedly attached to the bottom of a straight inner auger drive bar. A brace and bit arrangement at the top of the drive bar is for rotating the drive bar and either forcing it down toward the ice to bore a cylindrical hole of predetermined diameter through the ice or to force it up away from the ice after the hole has been bored to ream out a portion of that hole to form an inverted funnel shape opening. A tubular outer sleeve surrounds the drive bar and is movable between an upper boring condition and a lower reaming condition with respect to the drive bar. Two slotted longitudinally extending ice reaming blades are pivotally mounted at their top portions to the ream control sleeve. A reaming blade camming support bar attached to a bottom portion of the drive bar carries camming pins slidable in the reaming blade slots. These reaming blades move between position inside the predetermined diameter and partially outside of it with movement of the sleeve along the drive bar. | ||||||
| 246 | Foot powered ice auger | US618942 | 1984-06-08 | US4817735A | 1989-04-04 | Robert F. Corrigan |
| An ice auger driven manually by foot power through the instrumentality of a foot driven ratchet drive rotatably affixed to a set of bevel gears permanently mounted in a framework affixed to a stable base. An assymetrically shaped auger shaft with a rotatably mounted handle assembly and a permanently attached auger head is positioned vertically through, but not affixed to, the assymetrical bore of the horizontally positioned bevel gear permitting vertical movement of the shaft within the bore during operation. The combination of rotation created by the operation of the ratchet, the constant rotational force point on the auger shaft at the assymetrical bore of the horizontal bevel gear, combined with the simultaneous vertical movement of the auger shaft, results in a constantly changing point on the shaft where the bevel gear imparts rotational force. The vertical movement of the auger shaft is facilitated by the operator's downward pressure on the handle. | ||||||
| 247 | Soil sample core extraction tool | US90083 | 1987-08-24 | US4790392A | 1988-12-13 | James M. Clements |
| An improved soil sample core extraction tool including a handle member having a soil probe member movable within its longitudinal socket, and having a clutch means for selectively providing for extension, retraction and prevention of movement of the soil probe member with respect to the handle member so that the soil probe member can be inserted into the soil, and retracted with a soil sample, the handle member including a selectively usable jack which assists in retracting the soil probe member from the soil by incrementally lifting the handle member while the soil probe member is engaged by the clutch means, the jack including an extension arm to provide leverage for the jack. The soil probe member is elongated in length and allows for a continuous soil sample to be received in a hollow receptacle within the interior of the soil probe member. A hammer member having a rod with a collar, and a hammer section slidable on the rod, cooperates with the soil probe member to allow a hammer to assist in forcing the soil probe into the soil. A connection assembly allows an extension tube to be removably secured to the soil probe member. | ||||||
| 248 | Combination soil auger and soil core sampler with sample retaining capacity | US851586 | 1986-04-14 | US4653336A | 1987-03-31 | Arthur R. Vollweiler |
| A combination soil auger and soil core sampling apparatus has a cylindrical body with soil-cutting blades disposed at one end thereof and alternative cap and handle combinations attached at the opposite end for soil auger or soil core sampling use. In the soil auger mode, the body has an open cap with a bail and handle for augering into soil. In the core sampling mode, the body had a closed cap and handle combination and a removable sleeve insert within the body adapted to receive and hold a soil sample as the apparatus is rotated in the soil to be sampled. The sleeve insert is removeable for capping and retention of the soil sample. | ||||||
| 249 | Earth soil sampler | US564503 | 1983-12-22 | US4498547A | 1985-02-12 | Wayne Herkness, II |
| A portable and collapsible hand tool is disclosed wherein successive small samples of suspected contaminated earth soil may be directly deposited in a sampler bottle, following selective penetrations and extractions of the soil. The sampler is characterized by a substantial balanced mass which is vertically disposed above the sampler tool head, the head having in extension thereof a soil probe column which forms a tube of reverse draft, the same being interconnected to an inverted sampler bottle which is retained within the head where it is shock protected. | ||||||
| 250 | Extracting handle for earth drill augers | US167749 | 1980-07-11 | US4387483A | 1983-06-14 | Edward M. Larrabee |
| An extricator handle includes a quick snap-on feature for easy attachment to jammed earth augers. The invention preferably comprises a pair of hand grip bars, a receptacle box, an adaptor element and a locking bolt. The shaft of the jammed earth auger is received in a cavity in the adaptor element. The earth auger includes a spring-loaded pushbutton which locks into a complementary aperture in the sidewall of the adaptor element. The adaptor element is received in a cavity in the receptacle box. A threaded aperture in the adaptor receives the locking bolt which passes through another aperture in the receptacle box. The handle may be easily snap fitted onto the exposed shaft of a jammed auger and then manually turned to dislodge the auger from its jammed position. | ||||||
