Ratchet-Bar Egg Beater: Push a Rack, the Floats Spin Both Ways

Beating eggs in a closed beater keeps the air out, and a beater bolted to its vessel is slow to empty and clean. Harvey Miller of Cincinnati, Ohio, received US 18,759, dated 1 December 1857, for an egg beater: a frame whose standards clasp an open jar, a bar sliding through slots that gears into a pinion on a vertical spindle, and wire floats on the spindle that turn rapidly one way then the other as the bar is pushed to and fro; lifting the frame frees the jar. This rung works out the turns per stroke, then prints the rack and pinion, builds the frame and floats, and times a beating.
