The Prince Butter Cutter No. P306 was manufactured by Strite-Anderson Manufacturing Company, Minneapolis. It was patented on Aug. 16, 1932, by Albert Slaten, Minneapolis. The patent states:
“…primary object is to provide an efficient, practical, and comparatively economically constructed machine for use in restaurants, hotels and cafes, for dividing a large block of butter, such as a conventional pound unit, into small pieces or “pats” to be served the individual guests. The machine is grey porcelain over cast iron with a wooden knob on the crank handle. The block of butter is placed on the bed of the machine with one end against the small metal panel. The crank turns pushing the butter toward the wire pat cutters. The butter drops into a bowl of cold water where the pats can be fished out, dried, and served.
