| 221 | Combination weeding tool | US09915389 | 2001-07-26 | US06505869B2 | 2003-01-14 | Raymond J. Novotny |
| A weeding tool with a combination of attachments integrated with a fulcrum to remove specific types of weeds based on their root structure. The attachments remove weeds whose roots are characterized as lengthy single-type roots, medium-depth bushy-hair type roots and near-surface vine-type roots. A fulcrum slidably attached to the tool handle ergonomically assists the gardener in extracting weeds by limiting angular rotation of the handle. The fulcrum may be used to apply foot pressure in penetrating hard soil. The fulcrum slides on the tool handle with respect to the end of the lifting blade to vary its penetration depth and is used for extracting single-type weed roots at different depths. The multiple-tine rake rotatably attached to the fulcrum is snapped into position and spring-biased to remain in position for extracting weeds having medium-depth bushy roots. The cultivator bar rotatably attached to the fulcrum is snapped into position for near-surface weed removal or general soil tilling. A crevice blade, rotatably attached to the fulcrum removes weeds between the gaps of patio paving blocks and the like, is snapped into position for this task. Most of these attachments can be combined onto one tool or other combinations integrated with the slidably attached fulcrum. | ||||||

The device comprises essentially a spade or shovel blade of pointed configuration, which is carried at one end of a handle having at its other end a usual hand grip. Immediately above and adjacent the shovel blade there is detachably mounted a divided sieve or sifter having appreciable width, the two portions thereof being characterized by a shallow, dished configuration. The sifter or screen is made to be easily removable, and thus can be replaced by other screens having either larger or smaller perforations whereby either a coarse or else a fine sifting can be readily accomplished. A footpiece or stirrup member is provided on the handle adjacent the sifter and above the same, to enable the user to apply foot pressure for the purpose of inserting the shovel blade in the earth.
