Abstract: 461,543. Typewriters &c. DEFIANCE MANUFACTURING CORPORATION. Aug. 11, 1936, No. 22116. Convention date, Aug. 24, 1935. [Class 100 (iv)] Type-bar actions.-A machine for printing amounts on cheques comprises a set of spring-urged sliding type-bars arranged under rows of keys and each provided with a row of numeral types having a symbol type and a zero type at opposite ends thereof, the numeral types being selected by the keys, and the symbol and zero types being automatically selected by the aid of latches operated by the keys. To permit of use for different currencies, the machine may be provided with a slidable plate bearing word-types. In the machine shown in Figs. 1 and 7, sliding type-bars 5, arranged in two separated sets for printing amounts in dollars and cents, are mounted under rows of keys 1 ... 9. Each type-bar is provided with a row of types 8 consisting of numeral types, and a zero type arranged at the end of the row, and the dollar type-bars, excepting that for units, are provided at the opposite end of the row with a star type. The type-bars are formed with stops 9, 10 for co-operating with the keys 1 ... 4 and 5 ... 9 to arrest the type-bars when the selected numeral types register with the platen 61, the arrangement being such that the maximum movement of the type-bars is only half the length of a row of keys. The type-bars are formed also with stops 11 which co-operate with the framework 12 to position the zero types. The rows of keys for the dollar type-bars, excepting that for units, are arranged to depress latches 14 formed with projections 15 which are normally in the path of projections 16 on the type-bars. Each latch 14 is formed also with a projection 59 overlapping the adjacent latch of lower denomination. The type-bars are held by springs 58 in engagement with a laterally movable bar 17 which is connected to a spring 19 and has fingers 21 abutting on the framework 12. In operation, the amount is set on the keyboard, the cheque is placed on a table 67, and the bar 17 is retracted, by means of a chain 57 in connection with a cam-operated rock-arm 53, to permit of differential movement of the type-bars. The keys and the stops 9, 10 arrest the type-bars in position for printing numerals, the projections 15, 16 arrest the type-bars to the left of the highest significant numeral in position for printing stars, and the stops 11 arrest the dollar type-bars to the right of the lowest significant numeral in position for printing zero. The type-bars for cents and units of dollars move into position for printing zero if the associated keys are not depressed. For printing currency-designations, the machine is provided with a slidable plate 95, Fig. 7, which bears word-types for various designations, such as dollars and cents, and shillings and pence, and is movable by means of a finger-piece 96 to bring the selected wordtypes into printing position. A notched rod 99 and a co-operating spring-catch 97 hold the plate in position. The ú type is placed on one of the type-bars 8, and when the plate 95 is adjusted to print shillings and pence, the ú type is automatically moved into printing position by means of a rock-arm 102 which co-operates with a pin 104 on the type-bar and is arranged in the path of the rod 99.
