Bush, Vannevar

Description

These two flat round brass discs both have a hole down the middle for a shaft; a circle of smaller holes near the edge; and an indentation around the rim to hold a friction band (no friction band). Each has a small gear on one end. These are drums from frontlash units (compare to 1983.3002.04).

Parts of the Bush differential analyzer surviving at the Smithsonian have museum numbers MA.314824 and 1983.3002.01 through 1983.3002.89.
