Abstract: 239,621. Tappenden, L. B. June 19, 1924. Index type-wheel machines with two sets of type for perforating paper; hammer - impression type-carriages; letter-spacing mechanism.-A machine for filling in cheques or other documents comprises an horizontal and a vertical type-wheel provided with perforating-types for printing the amount in words and numerals respectively, means for simultaneously setting both type-wheels, means for simultaneously effecting impression from both type-wheels, and differential spacing- mechanism for spacing the words and numerals on the cheque. In the machine shown in rear elevation in the Figure, the word-type wheel a is provided with pivoted spring-supported arms a<1> carrying perforating types for printing the words "one," twenty, " thirty," " ninety," " hundred." " one thousand," " pounds," " shillings," " pence," and "and." The numeral-type wheel k is provided with perforating-types for printing spacing-marks and the numeral " 0 " - - " 19," and is mounted in a carriage k<1> running on guides k<2> supported by a pivoted frame y. The type-wheels are simultaneously rotated for character-selection by means of a laterally-movable bar d provided with a pointer c which is set with reference to a scale e. The type-wheel a is geared to a rack l on the bar d, and the type-wheel k is driven by gearing j - - g from an archimedean screw f actuated by the bar d. When the pointer is set opposite the graduation " ú," " s," " d," or " 0," a corresponding spacing-mark or type on the numeral-type wheel and a blank on the wordtype wheel are brought to the printing point. Similarly, when the pointer is set opposite a graduation such as " pounds " or " and " a .corresponding type on the word-type wheel, and a blank on the numeral-type wheel are brought to the printing point. The scale is provided with a graduation " ty " for setting the numeraltype wheel to print a final " 0 " in a number, the word-type wheel having a corresponding blank. Means may be provided for relatively adjusting the two type-wheels in accordance with the space between the word and numeral lines on the document. For instance, the word-type wheel may be driven by a rack arranged at rightangles to and geared to the rack l, the spindle of the word-type wheel being mounted in an adjustable support or being adapted to be placed in one or other of a number of sockets. The selected word and numeral types are simultaneously impressed on the cheque C by turning a crank q carried by a shaft p having a mutilated pinion u driving a pinion v on a shaft provided with cams w for depressing the frame y, the frame having a finger y<2> for depressing the wordtype. Differential feed-movements are imparted to the type-wheel k and the cheque C, for the purpose of spacing the words and numerals, by means of an archimedean screw z which engages a nut on the .carriage k' and is geared to a cheque-feeding roller r. The screw is provided with a pinion x geared by a loose pillion u<1> to a pinion t on a shaft s carrying a pinion n which moves laterally with the bar and is driven by one or other of a series of mutilated pinions o on the shaft p. The pinions have graded numbers of teeth and impart differential feed-movements corresponding to the width of the selected word-type. The cheque may be supported by a movable or stationary platen r<1>.
