Abstract: 843,622. Fish, gutting and filleting. ROWTON, H. S., SHAW, C., and ROBERTSON, R. Aug. 27, 1956 [Aug. 29, 1955], No. 24685/55. Class 28(2). A fish is pulled tail first and belly up by an endless conveyer through a heading device 23, then past a pair of self adjusting inclined disc knives 25 at 24 to cut the flesh from the belly rib bones, then past a pair of vertical disc cutters at 26 to cut off or partly off from the remainder, and finally past another pair of inclined boning disc cutters 29 at station 28 to cut off the side parts after being spread open by a guide to expose the vertical bone and remove all the remaining bone. At a subsequent station the tail may be cut off and/or the skin may be removed. If desired the first cuts off from the ribs at 24 may leave the back of the belly still attached to the spines of the backbone to leave a subsequent double folded over fillet, but otherwise two separate fillets are formed. To accomodate fish of varying sizes feelers 30 automatically adjust the zone of travel of the knives 25. The heading knives 43 Fig. 6 close together at the desired position on the neck when the fish nose passes out of a pair of feelers 31 which give a measure of the length of the fish. The cut may be complete or partial in accordance with the setting of the knives in which latter case the body is subsequently drawn away from the head and the attached guts, thereby gutting the fish. With a longer fish the feeler flaps 31 are unable to close, until by a timed cam 40 they are moved proportionately away from the fish so allowing the leading knife to operate. To cut along the rib bones the inclined disc cutters 25 are moved down towards the conveyer and as they move down the cutting peripheral positions become more widely spaced so that they follow the widening rib bones more closely. At station 26 vertical cuts are made on either side of the vertical bone which still remains in the fish by disc knives 27 which are moved to and away from the surface of the conveyer 20 so that the knives enter at the tail and cut along to the beginning of the belly and then rise clear of the fish for folded double fillet or they may cut along the complete length of the fish to make two fillets. At station 28 diverging guides 113 open the fish out to allow a pair of inclined rotary boning knives to finally detach the flesh from the bone. Two additional rotary knives may be provided to cut off the tail.
