454,006. Dressing fish. LASSEN, W. O., 17, Glash³ttenweg, Lubeck, Germany. March 23, 1936, No. 8619. [Class 28 (ii)] A machine for cutting off the belly flaps of fishes and removing the heads together with the entrails comprises spaced endless chains 4 carrying transverse troughs 5, 8, the parts 8 of which are connected rigidly with the chains, the parts 5 being resiliently connected thereto. The fishes are laid bellies upward in the troughs 5, 8, the heads protruding so as to be engaged by a bifurcated knife 27 which is adjustably mounted on the machine frame at 28, 29. When the fish is to be decapitated only, the fish head passes into the fork 27b, 27<c>, but when evisceration is to be effected, the knife 27 is adjusted so that the point of the upper fork 27<a>, 27b pierces the flesh at about the backbone and the knife edge 27b cuts or tears downwards into the back flesh, the head being thus half severed from the body. The belly of the fish is engaged by the edge 6<a> of the knife blade 6 which co-operates with the upper sharpened edge of the trough part 8 in scissorslike manner to cut off the belly parts protruding above the trough. The head is deflected by a guide 25 into a slot 24 in the blade 6, the head being thus retained so that continued movement of the fish with the trough pulls out the entrails. The fish head is ejected by means, not described, and the fish body drops into a receptacle beneath the conveyer.
