Abstract

Abstract This invention relates to an arithmetic unit for a postage meter in which the arithmetic and printing mechanism, commonly called ''''the meter'''', is removably attached to a heavy base by easily removable means, so that the arithmetic printing unit may be readily separated therefrom and taken to a Post Office for resetting. The mechanism of the present invention comprises a hollow cylindrical drive shaft on which is mounted a single Thomas-type mutilated drum actuator; driven gears slidably, but non-rotatably mounted on register drive shafts that are arranged on a concentric arc around the actuator; preferably a second Thomas-type mutilated drum actuator driven from said drive shaft; a second plurality of driven gears mounted on register drive shafts which are concentrically arranged in an arc around said second actuator; a descending register driven from one of said actuators and its associated driven gears and register drive shafts; ascending register driven by said second actuator and its associated driven gears and register drive shafts; a manually operated and ordinally arranged selection mechanism to simultaneously set into each of the orders of the registers driven by said register drive shafts, the value of the stamp to be impressed upon the mail matter; and a postage printing mechanism set by said manually operable selection mechanism and driven by the drive shaft. Preferably, the means for setting the printing mechanism comprises a set of first selection bars in the interior of said hollow drive shaft and set by the manually operated selection mechanism, and a set of second longitudinal, or axial, members resting on the exterior of said drive shaft and operable to set the printing mechanism; and means for interconnecting the interior and exterior longitudinally movable members.
