Abstract
The invention relates to apparatus for cutting and removing a core of ice from an expanse of natural ice such as, for example, a lake or river so that fishing can be accomplished through the remaining open hole. The apparatus consists of a cylinder with ice-cutting teeth on its lower end, lands around its periphery and a handle employed for rotating the cylinder.
Claims6
A combined ice-cutter and corer including:
- (a) a hollow cylindrical body having an open lower end and a substantially closed upper end;
- (b) a plurality of downwardly projecting ice cutting teeth arranged around the perimeter of the lower end of said body;
- (c) handle means on the upper end of said body for manually rotating said body;
- (d) a pair of primary lands extending helically upwardly on the outer surface of said body from a diametrically opposed pair of said teeth to said upper end;
- and
- (e) a pair of secondary lands each being located midway between a pair of primary lands and extending helically upwardly on the outer surface of said body from a diametrically opposed pair of said teeth part way up said body;
- whereby rotation of said body during a cutting operation causes said teeth to cut an ice core for entry into said body, and ice-swarf cut by said teeth is removed by said lands.
