Abstract: 714,575. Fish, cleaning and boning. FISADCO, Ltd. (Baader, R.). May 8, 1951 [May 8, 1950], No. 11422/50. Class 28(2) After a fish has been opened and entirely gutted the inner belly walls are rubbed by a rotary abrasive disc 2 which removes the black skin and loosens the rib bones, after which the backbone and attached ribs are removed. The fish 16 which is carried in the peripheral groove of a rotating drum 14 past the various heading and gutting tools then passes between a pair of spring- urged guide plates 22 and then its belly passes over a wedge-shaped guide 6 with a forked trailing end to direct the belly flaps, one on each side of the abrasive wheel 2. Spring-pressed fingers 50 of another guide 8 press the belly flaps against the wheel 2 to rub off the black skin and loosen the ribs. Thereafter the fish passes to a pair of toothed wheels 13 which engage and remove the backbone- and ribs. A sharp tip 66 of a curved guide breaks the backbone at the tail to facilitate removal by the boning wheels 13, and a wedge guide 70 holds the belly flaps apart during boning. The first pivoted guides 22 are urged together by a spring 31 but such movement is limited by an. adjustable screw 38 to suit the size of fish. The pressure of the fingers 50 on the belly flaps can be adjusted by a screw 57 pressing rubber blocks against which bears the back end of the levers constituting the fingers 50. The abrasive disc 2 can be moved in and out by mechanism as described-in Specification 676,814 to follow the line 18 of the base of the belly cavity.
