In an electromechanical coin totalizer, an escapement mechanism controls the movement of a totalizer arm in response to the deposit of coins of different denominations. The mechanism includes a first, fixed row of teeth on the arm and a second row of teeth shiftably carried by the arm for limited movement of the two rows of teeth relative to each other. The deposit of a coin of the largest denomination accommodated by the totalizer releases the totalizer arm and causes a retainer to engage and hold the second row of teeth to limit the movement of the totalizer arm, whereupon the second row is then released for return movement to its normal disposition in relation to the first row and the totalizer arm is relocked after having shifted through a displacement representing the value of such coin. When coins of lesser denomination are deposited, the first row is employed to control incremental movement of the arm.
