Soap-crutch′ing ma-chine′.

An apparatus for crutching (mixing) soap. That illustrated consists of an upright cylinder containing a number of radial fixed arms a a′ and spiral wings b b′ on a vertical shaft rotated by gearing. The soap is let into the top of the tank, and the spiral arms, being set in motion, act as screws, lifting the heavier materials from the bottom toward the top, and thoroughly intermingling the mass without forming air-bubbles. Any clippings and trimmings are also cut to pieces and incorporated.
