    摘要： A computing and recording register wherein integrating digital counters are driven by an input shaft to perform quantity, price and tax computations. The price and tax counters are driven by computer gearing coupled to the quantity counter drive gearing through a clutch. A two-stage advance mechanism rounds off the least significant digit of each of the counters and aligns the digits for printing quantity, price and tax data on a recording sheet at the conclusion of each transaction to be recorded. During the first stage, the quantity counter is advanced to align the digits while the clutch is engaged so that the price and tax counters are driven as the quantity counter advances. During the second stage, the clutch is disengaged and the price and tax counters advance independently of the quantity counter. Also included are a plurality of variable ratio gear trains adjustable through a translatable and rotatable selector shaft for changing one or more of the gear ratios to select the desired tax rate and price per quantity unit.

    摘要翻译： 计算和记录寄存器，其中集成数字计数器由输入轴驱动以执行数量，价格和税计算。 价格和税务柜台由计算机齿轮驱动，与通过离合器的数量计数器驱动装置相连。 两阶段提前机制舍弃每个计数器的最低有效数字，并在记录的每个交易结束时将打印数量，价格和税务数据的数字对齐在记录纸上。 在第一阶段期间，数量计数器被提前以在离合器接合时对准数字，使得价格和税计数器随着数量计数器的进行而被驱动。 在第二阶段，离合器脱离，价格和税计数器独立于数量计数器提前。
