Abstract
Abstract An improved auger-like device for boring holes in the earth comprising an elongated, rod-shaped brace member having a handle at one end and a U-shaped portion adjacent the handle suitable for rotative movement about the longitudinal axis of the brace. A cylindrical bit member having a sidewall which defines an open interior, is attached to an end of the brace. The bit member includes a plurality of teeth integral therewith and depending outwardly from its sidewall and spaced around the circumference thereof. The teeth include a plurality of inclined driving teeth interposed between longitudinally extending cutting teeth.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
237 words
A hand-operated garden tool for weeding and boring holes in the earth comprising: a. an elongated rod shaped member including a handle at one end and an elongated shaft at the other end, said elongated member adapted for rotative movement about its longitudinal axis when rotatably manipulated by the operator; b. a cylindrical boring bit having a sidewall which defines an open interior, said bit fixedly attached at one end thereof to the end of the shaft, the longitudinal axis of the cylindrical bit aligned with the longitudinal axis of the shaft, said boring bit also including a plurality of teeth depending downwardly from the terminal edge of the sidewall in spaced apart relationship around the perimeter thereof, said teeth comprising a plurality of inclined driving teeth angularly bent toward the open interior of the bit, each of said driving teeth having a leading edge and a trailing edge, said trailing edge being inclined a greater angle, relative to the sidewall of the bit, than the angular inclination of the leading edge and a plurality of longitudinally extending, cutting teeth aligned coextensively with the sidewall of the bit, said driving teeth and said cutting teeth alternately positioned with respect to one another around the perimeter of the sidewall of the boring bit, said sidewall also having a cutout portion positioned above the teeth to permit the removal of weeds and earth from the interior of the bit.

A hand-operated garden tool for weeding and boring holes in the earth comprising: a. an elongated rod shaped member including a handle at one end and an elongated shaft at the other end, said elongated member adapted for rotative movement about its longitudinal axis when rotatably manipulated by the operator; b. a cylindrical boring bit having a sidewall which defines an open interior, said bit fixedly attached at one end thereof to the end of the shaft, the longitudinal axis of the cylindrical bit aligned with the longitudinal axis of the shaft, said boring bit also including a plurality of teeth depending downwardly from the terminal edge of the sidewall in spaced apart relationship around the perimeter thereof, said teeth comprising a plurality of inclined driving teeth angularly bent toward the open interior of the bit, each of said driving teeth having a leading edge and a trailing edge, said trailing edge being inclined a greater angle, relative to the sidewall of the bit, than the angular inclination of the leading edge and a plurality of longitudinally extending, cutting teeth aligned coextensively with the sidewall of the bit, said driving teeth and said cutting teeth alternately positioned with respect to one another around the perimeter of the sidewall of the boring bit, said sidewall also having a cutout portion positioned above the teeth to permit the removal of weeds and earth from the interior of the bit.
Claim 3
Dependent Claim
53 words
The garden tool of claim 1 wherein the elongated rod shaped member includes a U-shaped portion integrally positioned between said handle and said shaft suitable for rotative movement about the longitudinal axis of the elongated rod shaped member when the handle is grasped and the U-shaped portion is rotatably manipulated by the operator.
