Oblique-Blade Potato Masher: Press and Turn the Ring
A masher that only presses leaves lumps where it did not land.
Robert Crane Jr. of Columbia, Pennsylvania, received US 171,603, dated 28 December 1875, for a potato masher: a ring joined to a central stem by six, eight or more wedge-shaped blades "inclined at angle of about twenty-five or thirty degrees," rigid with the handle so it can be "pressed vertically downward, and simultaneously revolved by the hand."
This rung works out how a turn drives the blades in, then prints the bladed ring, fits a stem and handle, and mashes a pan of potatoes.

The embedded blueprint splits the potato with teeth on a disk. Crane makes the blades the whole face and inclines them so a turn drives them through.

"Just above its cutting-edge these blades widen radially outward, and unite with the vertical inner face of the ring in an oblique direction, inclined at angle of about twenty-five or thirty degrees. This oblique position gives the upper and lower edges of the blades a sharp angle or cutting-edge, and the narrower triangular and oblique spaces between the blades renders this implement of superior utility and efficiency."

History and honest limits
History and honest limits
**Robert Crane Jr.** of Columbia, Pennsylvania, filed US 171,603 on 26 February 1875; it is dated 28 December 1875. The blades' upper edges rise outward to meet the ring's top, their lower edges are horizontal. He knew that a handle with oblique blades in a ring made a revolving churn dasher, and claimed only the potato masher of ring, blades and handle rigidly connected.
**Honest limits.** A printed head stands in for his metal one. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times are the result.
