Patent GB-429950-A (GB)
Abstract: 429,950. Calculating - apparatus. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. Dec. 11, 1933, No. 34801. Convention date, Dec. 12, 1932. [Class 106 (i)] [See also Group XX] A calculating-machine is combined with a photographic recording device for preparing a film record of numerical and other data entered into or computed by the calculating machine. The invention, in the form shown, incorporates an adding machine of the Burroughs type such as described in Specification 22464/09, [Class 106 (i)], and a photographic recording device in which representations of the item entered or the total printed by the adding machine are set up and photographed on the film strip during an operation of the adding machine. Provision is also made for reproducing a cheque or other document in juxtaposition to the numerical record and for photographing other data such as the serial number and date. As shown in Figs. 1 and 2, the adding machine comprises the usual set of numeral keys 100 and a bank of control keys 101 ... 104 for non-adding, transferring totals from one totalizer to another totalizer, sub-totalling, and total taking. The differential actuators are provided with the usual type sectors 108 and to each sector is connected a link 114 the other end of which is pivoted to a lever 115 operatively connected by means of a linkage 116 ... 118 to a corresponding slide member 120, Figs. 2 and 6, mounted in a guide on the base plate of the recording device. The slides are displaceable beneath a perforated masking plate 121 and are movable during an operation of the adding machine to set an indicating spot on each slide to a position corresponding to the value of the keys depressed. In total-taking or other control operation the rocking of a shaft differentially, depending on the key operated, imparts movement to a shaft 124 that is operatively connected to a supplemental slide 120T, Fig. 8, in order to set up the control data. Additional slides 120S may be provided for setting up by hand other representations for the date or other data. The masking plate 121 is provided with an angle bar 129 in order to set a cheque 130 into position so that it can be photographed. The plate 121 is also provided with an aperture 131 through which is exposed the reading of a counter adapted to register the serial number which together with other data printed on the masking plate can be photographed with the other data. On operation of the machine, the motor starting bar 105 is depressed to release a clutch so as to drive a shaft 110 through a complete revolution. This shaft through gearing drives a vertical shaft 139 in the recording device at the upper end of which is a gearing 140, Figs. 3 and 4, connected to a shaft 142 through an electromagnetically operated one revolution clutch 141, 143, 145. The clutch shaft 142 carries a mutilated gear 148 and a locking element 149 of a Geneva transmission gear 151 adapted to drive sprocket shafts 154, 155 for feeding the film record strip of the camera 156 from a supply roll 159 to a take up roll 160. The camera shutter 162 is operated by a shaft 163 having an arm 165 co-operating with a notched cam 164 on the shaft 142. For illuminating the masking plate lights 166 may be provided. In a modification two camera devices are provided; one for listing items and the other for recording totals. These devices are mounted on a slidable frame under the control of shift clutch magnets arranged in circuit with contacts controlled by the total-taking mechanism. British Specification 315,881, [Class 106 (i)], and U.S.A. Specification 1,054,628 also are referred to.
