866,436. Fish filleting. ATLAS A.S. Oct. 30, 1958 [Aug. 29, 1958], No. 34799/58. Class 28 (2). The belly of a cleaned cod is pressed on the barbs 8 of a U-shaped conveyer 7, Fig. 4, which pushes it tail first through two succeeding pairs of spaced rotated disc cutters 30 to 33, Fig. 10, to cut off the fillets from both sides. The vertebrae lie in the hollow of the U-shape 7 while the barbs engage between the side bones. The U- shaped conveyers 7 are at the top of conveyer plates 6 spaced along an endless driven chain. The fish first passes between inclined side-guides 14, Fig. 5, and then over arcuate hinged guides 17, 18, Fig. 9, where a press-down 21, Fig. 9, presses on the back of the fish and other side guides 24, 25 keep in the belly flaps. Another guide, Fig. 11, not shown, may direct the now freed top and bottom flaps against a further pair of disc knives 47, Fig. 13, to separate each bottom fillet from the top fillet and from the vertebrae. Some of the guides are serrated. The serrated guides 49, Fig. 14, serve to tear away the filmy membrane inside the belly flaps. The knives 45, 46 are lifted in time to prevent cutting into the side bones. The conveyer 7 has a spike 11, Fig. 2, with reverse barbs 9 on top.
