Abstract

In a fish scaling machine having a framework, a power source, a conveyor supporting one side of a fish and a hold down assembly yieldably engaging the other side of the fish, a descaler roll mounted on a drive shaft journaled upon the framework and connected to the power source. A pair of aligned engaging cylindrical roller bodies having right angular end faces are mounted end to end upon the drive shaft and secured thereto. Generally parallel helical teeth upon, around and projecting from each roller body, the teeth on said bodies being inclined rearwardly toward each other at an acute angle to the drive shaft. Teeth at their one ends extending to an end face of each roll body and with their other ends having axial projections extending outward of their other end faces, the teeth extensions of one roller body overlying the other roller body, extending between and interlocked with the adjacent teeth of the other roll body at their engaging end faces.

Dependent claims

In a fish scaling machine having a framework, a horizontally disposed conveyor adapted to supportably receive one side of a fish longitudinally movable thereover, a power drive, a series of longitudinally spaced first, second and third descaler rolls journaled upon the frame on axes at right angles to the direction of feeding, adapted to operatively engage said one side of said fish removing the scales therefrom as the fish are fed successively and continuously thereover, and a hold down and guide mechanism mounted upon the framework along said conveyor operatively and yieldably engaging the other side of the fish;

an improved first descaler roll comprising a drive shaft journaled upon said framework and connected to said power drive;
a pair of engaging cylindrical roller bodies with right angular end faces mounted end to end upon said drive shaft;
a radial set screw on each body in operative frictional and retaining engagement with said drive shaft;
generally parallel helical teeth on and around and projecting from each roller body;
the teeth of each body being inclined rearwardly toward each other and at an acute angle to said drive shaft;
said teeth at their one ends extending to one end face of each roller body, and at their other ends having axial projections outward of their other end faces;
the teeth extensions of one roller body overlying the other roller body, and extending between and interlocked with the adjacent teeth of the other roll at their engaging end faces.
