Today in 1973, US Patent 3749004 A was issued, an invention of William G. Pagdin and Charles F. Constable, assigned to the Schlitz Brewing Co., for their “Apparatus for Crushing and/or Compacting.” There’s no Abstract, although in the description it includes this summary:
The invention relates to that type of crushing and/or compacting machine or apparatus wherein a plurality of sets or pairs of opposing crushing rollers are arranged in series. Broadly according to the invention, a frame rotatably supports one roller from each set of rollers. The other roller from each set of rollers is rotatably supported by a member movable relative to the frame and the frame supported rollers. The rollers supported by the movable member move with that member relative to the frame supported rollers to provide for relief from shock loading between the sets of opposing rollers. Relative movement between the opposing rollers to relieve shock loading there between is resisted by resilient means.
