Abstract
Abstract Fish butchering apparatus for separating a fish into a main loin section and a lower head and belly section. The apparatus includes a power-operated vertically movable knife which is urged towards and away from a horizontal table upon which a fish is positioned. Means on the table cooperate to position a fish so that the knife will cut downwardly through such fish along a line extending approximately from the center of the eye to the vent regardless of the size of the fish.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
Butchering apparatus for use with tuna-like fish of various sizes, comprising; a frame having a horizontal table, the upper surface of said table receiving fish to be butchered; a vertically movable knife carried by said frame; power-operated means interposed between said frame and said knife to urge said knife downwardly towards said table, to butcher a fish disposed on its side upon the upper surface of said table and to thereafter raise said knife; a fixed belly-engaging guide on said table; a transversely movable back-engaging plate on said table; a longitudinally movable nose-engaging plate on said table; and linkage means operatively interconnecting said plates to cause said nose-engaging plate to automatically move a predetermined longitudinal distance when said back-engaging plate is moved a transverse distance corresponding to the width of a fish to be butchered, whereby said guide and said plates will position different sizes of fish so that said knife will cut downwardly through said fish along a line extending approximately from the center of the eye to the vent of said fish.
Claim 2
Dependent Claim
174 words
Butchering apparatus for use with tuna-like fish of various sizes, comprising; a frame having a horizontal table, the upper surface of said table receiving fish to be butchered; a vertically movable knife carried by said frame; power-operated means interposed between said frame and said knife to urge said knife downwardly towards said table, to butcher a fish disposed on its side upon the upper surface of said table and to thereafter raise said knife; a fixed belly-engaging guide on said table; a transversely movable back-engaging plate on said table; a longitudinally movable nose-engaging plate on said table; and linkage means operatively interconnecting said plates to cause said nose-engaging plate to automatically move a predetermined longitudinal distance when said back-engaging plate is moved a transverse distance corresponding to the width of a fish to be butchered, whereby said guide and said plates will position different sizes of fish so that said knife will cut downwardly through said fish along a line extending approximately from the center of the eye to the vent of said fish.
Claim 3
Dependent Claim
