1,090,321. Filleting fish. LAPINE BROS. Inc. Jan. 29, 1965 [Jan. 30, 1964], No. 4147/65. Heading A2U. A machine for filleting fish comprises a reciprocating cutter 120 with two cutting edges for removing the rib bones from opposite sides of the fish, the cutter extending obliquely to the rib bones and its reciprocating movement being at an angle to the direction of movement of the fish. The cutter 120 is reciprocated by piston mechanism 127. The machine also comprises endless conveying belts which are pressed against the sides of the fish by rollers, means 24-27 for guiding the fish, rotary ventral cutting discs 61, rotary eviscerating or cleaning wheel 68, rotary dorsal cutting discs 91, manifold 161 for supplying water to various parts of the machine and trough 165 for collecting the waste material. Guides means 24 has a groove on its upper surface which groove tapers towards discs 61. Guide means 25 and 26 have rail portions which engage in the ventral slits, guide means 25 spreading apart the sides of the fish. Guide means 27 spreads apart the fish sections and has plates 105 against which the fish sections are pressed to deform the rib cages to substantially planar configuration. In use, the endless belts convey beheaded fish along guide 24, over discs 61 which make ventral cuts on opposite sides of the belly spikes to a depth adjacent the backbone, over wheel 68 which cleans out the belly cavity, under discs 91 which make dorsal cuts which intersect the ventral cuts and sever the side portions of the fish from the backbone which is discharged, and past reciprocating cutter 120 which severs the rib bones, beginning at the ends of the ribs which were severed from the backbone.
