Stepped Spiral Egg Beater: A Stepped Dasher Spun in a Square Box
A beater spun in a round bowl soon drags the whole mixture round with it.
Thomas McBean of Fowlerville, New York, received US 24,134, dated 24 May 1859, for an egg beater: "a double spiral-shaped beater or dasher with its surface formed into steps within a square box," turned horizontally on a vertical shaft by a bevel pinion and a handle, so that the dasher and the square box together "so thoroughly breaks up all portions of the eggs that they may be well and very thoroughly beaten in a few seconds."
This rung compares the side and corner gaps, then prints the stepped dasher, builds a square box with a bevel drive, and times beating in the box against a round bowl.

"The nature of my invention consists in arranging a double spiral-shaped beater or dasher with its surface formed into steps within a square box and in communicating to this dasher a swift rotary motion so as to revolve it horizontally within said box."

Screw a hardwood bar across the box's top with a bracket above it. Run a 5 mm rod down through the bar to a socket in the floor, with the dasher at its foot and one bevel gear at its top; mount the other gear on a crank shaft through the bracket so they mesh.

History and honest limits
History and honest limits
**Thomas McBean** of Fowlerville, Livingston County, New York, received US 24,134, dated 24 May 1859. The dasher's spiral circular plates are soldered to a small tube and bent into steps radial from the axis; the shaft passes up through the box's cover to a bracket, its lower end resting on a pin in the box's bottom. He claimed the double spiral dasher in combination with the square box.
**Honest limits.** FDM prints hold food in their layer lines, so wash well and replace when worn. A printed dasher and a bought 1:1 bevel pair stand in for his tin plates and pinions. Your times are the result.
