A calculator of the type with successive digit or numeral wheels with improved carryover or transfer means between wheels. Transfer wheels are used between successive digit or numeral wheels. Each digit wheel has a finger or projection which picks up abutments on a transfer wheel for driving it and effecting the transfer or step movement. The transfer wheel has spaced abutments which are picked up by the projection on the digit or numeral wheel. These abutments on each transfer wheel are displaced angularly from ten predetermined stopping positions of the transfer wheel. When there are simultaneous transfers or carryovers of several digit wheels, there is a slight delay in the pick up of each transfer wheel for effecting the transfer with the result that the transfer takes place sequentially thereby eliminating the imposition of a sudden, heavy torque load on a single driving digit wheel.
