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.
