notes: label: Description
content: This compact pinwheel lever-set and manually operated non-printing calculating machine has a steel mechanism and housing. Nine slots contain levers for setting numbers. The levers rotate forward to set digits. A steel crank with a wooden handle that extends from the right side of the machine rotates backward (clockwise) for addition and multiplication and forward (counterclockwise) for subtraction and division. A wing nut on the left side zeros the setting levers.
label: Description
content: At the front of the machine is a movable carriage with 13 windows that show dials of the result register on the right and eight windows for the revolution register on the left. The revolution register has no carry. Sliding decimal markers are on a rod over the result register. Depressing a lever at the front of the machine releases the carriage for shifting. Wing nuts at the ends of the carriage are used to zero the registers on it. A bell on the left end of the carriage rings when the result changes sign (as in over division). The machine sits on a wooden base.
