Patent GB-499379-A (GB)
Abstract: 499,379. Punching statistical data. HODGES, A. P., and SMITH & SON, Ltd., W. H. (Sherman, J. Q. [in part]) July 20, 1937, No. 20111. [Class 31 (ii)] [Also in Group XIX] A portable bill or ticket issuing machine of the autographic-recorder type, having rolled-up bill and record strips, is provided with a row of punches selectively operable to perforate records of transaction amounts in both strips simultaneously. First embodiment. The bill strip 8, Figs. 4 and 5, is provided with edge perforations to enable it to be fed by pin-wheels 10 on a manually rotatable spindle 9. The strip passes from a supply spool 2, through a gate 6 between a punch-box 4 and die-plate 5, over an autographic platen 12 to a severing edge 24. The record strip 11 passes front a supply spool 3 through the gate 6, and is wound on the spindle 9, the arrangement being such that the bill strip is fed to greater extent than the record strip at each machine operation. After the items of a transaction have been entered in columns A of the bill, a record of their total is perforated in column B and in the record strip by depressing keys 14 operatively connected to the appropriate punches 13. To renew the supply spools, a cover 21 is rotated about its forward end and hinged members 19 carrying the upper halves of the spool bearings are raised to free the spools. A second lockable cover may prevent unauthorized access to the record strip. When the machine is utilized for ticket-issuing some of the punches are allocated to the punching of such information as the class of ticket, the fare stage and code numbers. Second embodiment. The bill strip 53 and record strip 54, Fig. 7, pass from a common supply spool 32 to a gate between a punch-box 50 and die-plate 51, whence the record strip proceeds to a storage spool 33 and the bill strip passes out of the casing to be severed against an edge 72. Both strips are advanced by rotating the storage spool, for which purpose an end flange 45 of the latter is connected by a pin 44 to a disc fast on a manually rotatable shaft 40. Reverse rotation of the shaft and spool is prevented by a pawl 46, the serrated edge of which is caused to grip the bearing 41 of the shaft when the latter is turned counterclockwise. The punches 56 are arranged in a row and are depressible by a stylus to perforate the strips. To indicate which punches have been operated, complete restoration of each depressed punch by its spring is prevented by an associated latch 60 urged by a spring 62 to intercept a shoulder on the punch. At the end of the operation, the latches are simultaneously disabled by a manually-operable member 63 co-operating with pins 64 on the latches. Additional punches may be provided in the direction of length of the strips. Specifications 306,765 and 326,531, [both in Class 31 (ii)], are referred to.

Abstract: 509,206. Calculating - machines. MERCEDES BUROMASCHINEN - WERKE AKT.-GES. Sept. 16, 1938, No. 27060. Convention date, Oct. 6, 1937. [Class 106 (i)] The invention relates to a totalizer having two sets of numeral wheels so arranged that one set always indicates the complement of the amount indicated by the other set, one set being read when the total is positive and the other set when it is negative, the set not in use at any time being obscured by a manuallyoperated shutter. According to the invention, the shutter is normally locked, excepting in certain positions of the moving paper carriage. The operation of the shutter may also insert the fugitive one and may operate means controlling the kind of operation to be performed later. The totalizer 2 is detachably secured to a rail 1 of the movable paper carriage and is engaged denomination by denomination with a master actuating wheel as the carriage moves. A slidable shutter 4 is moved downwards to obscure the positive numeral wheels 3 and reveal the negative wheels (not seen -in Fig. 1), this movement being effected by swinging anticlockwise a finger lever 27 about its pivot 28, the lever being secured to a sector 21 engaging teeth 20 on the shutter 4. The sector also has other teeth 24 gearing with a sector 25 operating fugitive-one mechanism (not described). The end 18 of the shutter 4 operates a member 19 controlling the kind of operation to be performed later. The sector 21, and hence the finger lever 27 are normally locked by a pawl 47 pivoted at 49 and formed with a projection 52 engaged by a locking lever 53 pivoted at 54 and having a cam end 62. The finger lever 27 is unlocked when the carriage stands in either of two positions. In one of these, a cam 63 depresses the cam end 62 and in the other a cam 66 depresses the cam end. The cam 66 is integral with a fixed member 64 and the cam 63 is adjustably secured to this member. The distance between the cams is set according to the width of the totalizer so that the cam 63 engages the cam end 62 when a fixed mark 64a registers with the left-hand edge of the totalizer casing, the cam 66 engaging when the carriage has moved until the mark 64a registers with the right-hand side of the totalizer casing.
