Title: Improvements in or relating to washing machines
IPC: D06F45/00
Filed: 1934-09-18
Abstract: 422,462. Cash registers. ANKERWERKE AKT.-GES., Bielefeld, Germany. July 30, 1934, No. 22216. Convention date. Aug. 26, 1933. [Class 100 (iv)] [See also Group XIX] Index type-wheel machines.-In a cash register for registering and recording amounts in different currencies and provided with currency-selecting and amount-setting means, the currency-selecting means controls the positions to which the amount-setting means can be set. The invention is described as applied to a differentially-set cash register having six setting-levers 1, Fig. 1, for the units and higher denominations, two levers 2, 3 for shillings or the tenths and hundredths of a decimal system, two levers 4, 5 for pence and farthings, and three levers 6-8 for selecting the particular monetary system. Each lever communicates its setting to a type-wheel 16, Fig. 2, with which a pair of printing-platens 17, 18 co-operate for printing upon a record strip and inserted slip, the type being formed either with points or as inclined knife-edged plates to penetrate or incise the paper. The machine may be provided with a single group of totalizers for accumulating the amounts in each currency, the desired totalizer being selected by the currency-selecting levers. To prevent the adjustment of the setting-lever 2 past the ten position when the lever 6 is in its uppermost position to select the British monetary system, a locking-arm 26, Fig. 4, fast on a shaft 23, presents a shoulder 32 in the path of a stud 33 on the lever 2. However, upon the adjustment of the lever 6 out of its uppermost position to select a decimal system, the arm 26 is rocked clockwise to free the lever 2, the shaft 23 being connected for this purpose to the lever 6 by means of an arm 24, Fig. 2, a cam slot 22 in which embraces a stud 21 on the lever. This adjustment of the lever 6 through an arm 25, Fig. 3, on the shaft 23, serves also to lock the pence and farthing setting-levers in zero position by interposing a shoulder 28 on the arm in the path of studs 29 on the levers. Curved surfaces 27, 31 on the arms 25, 26 co-operate with the studs 29, 33 respectively to prevent adjustment of the currency-selecting lever 6 into its uppermost position after the movement of lever 2 past the ten position, and adjustment of the lever 6 from its uppermost position after the movement of either of the levers 4, 5 from zero position.
