Abstract
Abstract Method of butchering frozen whole fish including the subdivision of the whole fish into a plurality of cross sections thereof and subsequently subdividing the cross sections into frozen segments the junctures between which are along lines which are general parallel to the longitudinal axis of the fish and to the skeletal structure thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
83 words
The method of butchering fish which have previously been frozen comprising a. subdividing the fish by dividing the loin-bearing portions along planes approximately normal to the major skeletal axis of the fish into a plurality of discrete bilaterally symmetrical frozen sections having predetermined thicknesses, b. thereafter skinning said sections, and c. operating on said skinned sections to effect separation of the scrap parts of the sections from the loin meat parts while the latter are still in at least a partially frozen condition.
Claim 2
Independent Claim
83 words
The method of butchering fish which have previously been frozen comprising a. subdividing the fish by dividing the loin-bearing portions along planes approximately normal to the major skeletal axis of the fish into a plurality of discrete bilaterally symmetrical frozen sections having predetermined thicknesses, b. thereafter skinning said sections, and c. operating on said skinned sections to effect separation of the scrap parts of the sections from the loin meat parts while the latter are still in at least a partially frozen condition.
Claim 3
Dependent Claim
37 words
The method of butchering fish as claimed in claim 1 further comprising d. subjecting the peripheral areas of the sections to thermal treatment to cause at least a partial thaw prior to performing the step of skinning.
Claim 4
Independent Claim
71 words
The method of butchering fish which have previously been frozen comprising a. subdividing the principal loin-bearing portions of the fish while same is still substantially frozen generally transversely to the longitudinal axis thereof to form a plurality of frozen sections, and b. thereafter subdividing said frozen sections into loin segments while at least the flesh of same is still at least partially frozen, along lines substantially parallel to the skeletal structure.
Claim 5
Independent Claim
71 words
The method of butchering fish which have previously been frozen comprising a. subdividing the principal loin-bearing portions of the fish while same is still substantially frozen generally transversely to the longitudinal axis thereof to form a plurality of frozen sections, and b. thereafter subdividing said frozen sections into loin segments while at least the flesh of same is still at least partially frozen, along lines substantially parallel to the skeletal structure.
Claim 6
Dependent Claim
28 words
The method as set forth in claim 3 including the step of removing the skin from the fish in an operation subsequent to the transverse subdivision of same.
Claim 7
Dependent Claim
30 words
The method as set forth in claim 3 including the step of removing the viscera from the visceral cavity in an operation subsequent to the transverse subdivision of the fish.
Claim 8
Dependent Claim
23 words
The method of claim 1 further comprising the step of grading the first subdivided sections in accordance with their physical characteristics and quality.
Claim 9
Dependent Claim
22 words
The method of claim 3 further comprising the step of sorting the second subdivided loin segments in accordance with their physical characteristics.
Claim 10
Independent Claim
79 words
The method of butchering a previously frozen fish carcass comprising a. cutting laterally through the frozen carcass to divide the carcass into a number of frozen transverse discrete sections, b. removing the frozen viscera from the visceral cavity by punching out the viscera through the larger end of the section of the visceral cavity, c. skinning the sections, and d. also removing the skeletal structure and frozen blood meat portions leaving the valuable loin meat divested of waste material.
Claim 11
Independent Claim
79 words
The method of butchering a previously frozen fish carcass comprising a. cutting laterally through the frozen carcass to divide the carcass into a number of frozen transverse discrete sections, b. removing the frozen viscera from the visceral cavity by punching out the viscera through the larger end of the section of the visceral cavity, c. skinning the sections, and d. also removing the skeletal structure and frozen blood meat portions leaving the valuable loin meat divested of waste material.
Claim 12
Independent Claim
96 words
The meThod of butchering fish which have been previously frozen comprising a. subdividing the frozen fish into a plurality of frozen transverse sections by making multiple cuts through the fish, said cuts being made approximately at right angles to the backbone of the fish, b. removing the viscera from the visceral cavity in an operation subsequent to the subdivision of the fish, and c. dividing said frozen sections into segments of loin meat parts and scrap parts by making cuts through the sections, said cuts being made approximately parallel to the back bone of the fish.
Claim 13
Independent Claim
96 words
The meThod of butchering fish which have been previously frozen comprising a. subdividing the frozen fish into a plurality of frozen transverse sections by making multiple cuts through the fish, said cuts being made approximately at right angles to the backbone of the fish, b. removing the viscera from the visceral cavity in an operation subsequent to the subdivision of the fish, and c. dividing said frozen sections into segments of loin meat parts and scrap parts by making cuts through the sections, said cuts being made approximately parallel to the back bone of the fish.
Claim 14
Independent Claim
78 words
The method of butchering a previously frozen fish carcass comprising a. cutting laterally through the frozen carcass to divide the carcass into a number of frozen transverse discrete sections, b. removing the viscera from the visceral cavity of each section by forcing the viscera out of the larger end of the visceral cavity, c. skinning the sections, and d. also removing the skeletal structure and frozen blood meat portions leaving the valuable loin meat divested of waste material.
Claim 15
Independent Claim
78 words
The method of butchering a previously frozen fish carcass comprising a. cutting laterally through the frozen carcass to divide the carcass into a number of frozen transverse discrete sections, b. removing the viscera from the visceral cavity of each section by forcing the viscera out of the larger end of the visceral cavity, c. skinning the sections, and d. also removing the skeletal structure and frozen blood meat portions leaving the valuable loin meat divested of waste material.
