| 61 | Tools and methods for retrieving buried coins and other treasure | US10858604 | 2004-06-02 | US07121356B2 | 2006-10-17 | Kenneth E. Michael |
| A “sod saver” tool for digging to acquire an object buried in the ground, and a non-metallic scraping tool utilized when carefully examining the soil. The sod saver tool includes a main cylindrical body rotated about its longitudinal axis for digging a substantially cylindrical plug of soil from the ground, the object being contained in the plug of soil, and a plurality of circumferentially-disposed resilient non-metallic fingers located at a bottom portion of the main cylindrical body. When the digging of the plug is being performed, the resilient fingers tend to spread radially outward from the longitudinal axis of the main cylindrical body, being deflected away from directly hitting and scratching the buried object, tend to generally direct the soil upwardly into the main cylindrical body, and tend to cause the plug to be substantially-compacted and cylindrical. The compacted plug may be easily reinserted into a hole in the ground. The sod saver tool also includes a rod with markings for setting a digging level, with a retractable cutting tool with teeth attached to the rod. | ||||||
| 62 | Garden tool | US10151231 | 2002-05-20 | US20020189827A1 | 2002-12-19 | Robert Edward Constable |
| A garden tool with a non-slip handle grip, designed for immediate and not difficult removal of deep-rooted plants such as Thistle and Dock weeds. The body of the tool is of rigid and strong construction, with angled cutting faces and includes a plant/soil containment chamber. The tools angular cutting faces and profile, are designed to produce efficient insertion and soil compression when downward thrust is applied, which therefore holds captive the plant root in the containment chamber, hence achieving successful plant removal from the ground when the tool is withdrawn. The slotted front of the containment chamber allows for unwanted plant and soil removal from the tool. Optional hand and foot cross-members added, to produce more forceful insertion into and easier withdrawal from the ground, and to create a convenient standing operating stance, when using the tool. | ||||||
| 63 | Working tool | US09781701 | 2001-02-13 | US20020108762A1 | 2002-08-15 | Earl Lynch |
| A working tool (10) is disclosed having an elongated shaft (11), a handle (12) mounted generally perpendicular to one end of the shaft (11), and a ground working head (13) mounted to an opposite, lower end of the shaft (11). The working tool (10) also includes an annular step plate (16) mounted upon the shaft for rotary movement relative to the shaft 11. An upper stop (7) and a lower stop (18) are also coupled to the shaft (11) above and below the step plate (16), respectively. | ||||||
| 64 | Mini hole digger | US389736 | 1999-09-07 | US6123374A | 2000-09-26 | Ernest Elder |
| A new and improved mini hole digger with a handle having a hook secured to a lower surface thereof and two shafts, each of which is secured to the lower surface of the handle inward of an end portion thereof. A foot lever has two apertures formed therethrough. The foot lever has a hook secured thereto between the two apertures formed therethrough. A securement aperture is formed in a lower surface between the two apertures formed therethrough. The two apertures slidably receive the two shafts therethrough. The two apertures function to allow the foot lever to slide up and down along each of the two shafts. A spring is secured to the hook of the handle and to the hook of the foot lever. A digger housing has an aperture formed therethrough. The housing is secured to each of the two shafts outward of the aperture formed therethrough. The housing has a plurality of jagged edges integral therewith. A rod is received within the digger housing. The rod is secured to the securement aperture of the foot lever through the aperture formed through the digger housing. The rod has a push plate secured to its other end. | ||||||
| 65 | Posthole digger and cleaning attachment | US613840 | 1996-03-11 | US5685587A | 1997-11-11 | Ronald Glenn Putnam, Jr. |
| A posthole digger includes first and second spaced-apart and substantially upright handles for being gripped by a user at respective free ends. First and second cooperating blades depend from respective proximal ends of the handles. A cleaning attachment is located between the handles for removing accumulated earthen matter from an inside surface of the first and second blades when in the open position. An elongate rod extends between the handles, and is received within a hollow sleeve for sliding vertical movement relative to the sleeve. An inner scraper is attached to an end of the rod, and positioned between the first and second blades for reciprocating vertical movement along the length of the blades in the open position. A coil spring normally urges the inner scraper upwardly into a storage position adjacent to a top end of the blades. An extension is secured to the inner scraper for being depressed by the foot of a user against the force of the spring to move the inner scraper downwardly along the length of the blades. | ||||||
| 66 | Hammer driven soil coring device | US461081 | 1990-01-04 | US4974682A | 1990-12-04 | Michael R. Hoffman |
| A hammer driven soil coring device for use on golf course greens having a cylindrical cutting tube that has a lower cutting edge and longitudinally extending guide slots which serve as a guide for an ejector plate. Affixed to the cylindrical cutting tube is a cutter cap to which is affixed a support tube. The support tube has one vertically oriented slot. The slot serves as a guide for a stop which serves as a device to control the depth that a tamping plate achieves when the cylindrical cutting tube is driven into the surface of the green. A hand knob extends through the slot into a cylindrical rod for extending the tamping plate beyond the cylindrical cutting tube and to lock the tamping plate into a fixed position. A bubble level is located within the support tube. An impact head is located at the end of the tube with an aperture that allows the operator to view a bubble level. A handle extends perpendicularly through the impact head as well as the support tube and is affixed to each by means of a spring lock pin. | ||||||
| 67 | Weed extracting tool | US21205 | 1987-03-03 | US4715634A | 1987-12-29 | Teresa L. Mueller; Michael W. Mueller |
| A weed extracting tool includes an elongated shaft having a handle at its upper end and a cutting head at its lower end. The cutting head includes a tubular housing and a semi-circular blade depending from the housing. An ejector device is reciprocable within the tubular housing for clearing weeds and soil from the cutting head. The ejector is biased to an extended position by means of a compression spring. A latching device holds the ejector in a retracted position against the bias of the spring. | ||||||
