(Cl. 235-83) 1 This invention relates to pay roll time calcu lators wherein the time worked by an employee, even ,though gaps in his time for lunch hours have been had, can readily be ascertained. It is an object of the present invention to pro vide a simple hand calculator that can be rested upon the desk of a time clerk and by the simple manipulation of two relatively movable parts, a reading of the total hours worked during the day can be easily reckoned. ` 2 Fig. ’7 is a- fragmentary face view of the dials and indicators showing the reading after the ñxed dial has been adjusted and the later hours added to the rotating dial as a result of the knob having been moved to the later stopping time, Fig. 8 is a perspective view of a modified form of calculator which has an inclined front and is mounted in a casing.
