Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
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.
Claim 2
Dependent Claim
159 words
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.
Claim 3
Dependent Claim
51 words
A device as claimed in claim 1 wherein said pair of secondary lands extend helically upwardly from said pair of diametrically opposed teeth for one quarter the circumference of said body, whereby ice-swarf removed by each secondary land is deposited on the next primary land for removal from around said core.
Claim 4
Dependent Claim
26 words
A device as claimed in claim 2, wherein each cutting tooth is provided with a curved surface for transferring ice-swarf from said teeth to said lands.
Claim 5
Dependent Claim
54 words
A device as claimed in claim 3, wherein said handle is axially slidable in said body, means are provided for securing said handle to the closed end of said body for rotation of said body, and said handle is provided with a pivotted ice probe for assisting in the removal of an ice core.
Claim 6
Dependent Claim
16 words
A device as claimed in claim 4, wherein said body is coated with a thermoplastic material.
Claim 7
Dependent Claim
23 words
A device as claimed in claim 4 including 8 ice cutting teeth arranged around the perimeter of the lower end of said body.
