Abstract
An auger for drilling fishing holes in ice on a body of water has an elongated shank supporting a continuous helical flight and a plurality of partially helical scoop-like members having leading generally radial edges, ice cutting blades releasably fastened to the members adjacent their leading edges having outer portions that extend radially outward from outer edges of the members supporting the blades and serrated forward cutting edges, and a positioning pin secured to the lowermost end of the shank for drilling a positioning hole in the ice.
Claims23
An apparatus for making a fishing hole in ice on a body of water comprising:
- an auger having an elongated shank, a helical flight secured to the shank, said helical flight having a bottom leading edge and a vertical edge, a partially helical scoop-like first member having a generally radial trailing edge and a generally radial leading bottom edge, means securing the trailing edge to the bottom leading edge and vertical edge of the helical flight, an ice cutting first blade, means securing the ice cutting first blade to the helical scoop-like member adjacent the leading bottom edge of said member, a partially helical scoop-like second member having a generally vertically extending edge secured to the shank, an arcuate trailing edge extended generally radially outwardly and downwardly spaced from a lower portion of the helical flight, and a generally radial leading bottom edge, an ice cutting second blade, means securing the ice cutting second blade to the second member adjacent the bottom leading edge of the second member, and a positioning point secured to the lowermost end of the shank aligned with the longitudinal axis of the shank for drilling a positioning hole in the ice.
