Toothed-Disk Potato Masher: Teeth Split It, Holes Take It

A perforated masher only pushes; firm pieces roll away from the holes. George A. Anderson and Charles J. Baker of Albany, New York, received US 108,083, dated 11 October 1870, for a utensil for preparing potatoes and meat: a metal disk with several series of incising teeth and perforations placed alternate, the teeth's width radial; pressed down, "the incisors ... will enter the vegetables and split them at each point in contact, when the broken portions of the vegetables operated upon will rise up and pass through the openings." This rung works out the teeth and open area, then prints the disk, fits a handle, and mashes potatoes.
