Patent GB-524746-A (GB)
Abstract: 524,746. Cash registers. INTERNATIONAL BUSINESS MACHINES CORPORATION.. Feb. 6, 1939, No. 3847. Convention date, March 24, 1938. [Class 106 (i)] Relates to machines of the type provided with a reciprocable main operating mechanism, check issuing and printing and platen rollers driven by a one-way clutch driving means from the main operating mechanism, a set of amount printing type and an impressior platen therefor operated by the main operating mechanism for printing an amount either upon an inserted slip or upon a check, and consists in the provision of keyoperated disconnecting means for disconnecting the clutch and rendering idle all check-issuing and check-printing during slip-printing operations. The invention is described as applied to a machine of the kind disclosed in Specification 497,154. The machine is now provided with means for printing alternatively upon a voucher or an inserted slip. In the normal condition of the machine, the item and date are printed by separate platens upon a voucher strip, Fig. 1a, which is then fed and impressed with constant matter by the rotation of an electro-roller. However, in an operation in which a " Slip " key is depressed, the date platen and electroroller are disconnected from the main operating means and an inserted slip is impressed with the item only. Type-wheels and hammer-impression.-The item type-wheels include amount wheels 89, a transaction wheel 95 and a clerk's wheel 96, and are mounted on a shaft 97 for adjustment by the differential mechanisms. The date typewheels 101, 102 are also mounted on shaft 97 and are adjustable by knobs 103. A platen 105 co-operates with the item type-wheels and is actuated during each operation by a cam 210 fast on a sleeve 211 of a shaft 110, which sleeve is rocked counterclockwise upon the depression of the main operating bar by means of a toothed sector 115 linked thereto. A second platen 106 co-operates with the date typewheels and is actuated only in voucher-issuing- operations by means of a cam 209 fast on the shaft 110, which shaft is rocked counterclockwise upon the depression of the operating bar by teeth 138, Fig. 8, of a plate 134 normally connected to the sector 115 by a latch 136 taking over a lug 137 of the sector. A singleink-ribbon 131 is effective for impressing a voucher or slip. Voucher-issuing.-The voucher strip 120 passes from a supply roll 119, around a guide 122 between the type wheels 89 &c. and the platens. 105, 106, between electro and platen rollers 125, 126, and is delivered through an edged aperture 129 in a plate 128. The strip is impressed by both platens as the operating bar reaches the limit of its depression. As the bar returns, teeth 138<SP>1</SP>, Fig. 8, on the plate 134 become operative through a one-way clutch to rotate the electro and platen rollers, which impress the strip and issue the voucher through the aperture 129. The voucher is torn off against the edge of the aperture, the strip being clamped between the apertured plate 128 and a flexible plate 127 by a spring-urged bail 156 that abuts against the underside of the latter. Cam means lower the bail during the machine operation to permit the voucher to be issued. A flat is formed on the electro roller to permit the insertion of a slip. Inserted slip.-Upon the depression of a " Slip " key 162, Fig. 5, the date platen and electro-roller are crippled to enable a slip inserted through the side of the machine to be impressed with the item only. For this purpose, a nose 163 of the " Slip " key co-operates with a shoulder 164, Fig. 8, of the latch 136 whereby the latter is disabled when the key is depressed, thus disconnecting the plate 134 and associated mechanism from the operating bar. The " Slip " key is held depressed by a detent 166 until the latter is crippled, during the depression of the operating bar, by a stud 114 on the sector 115 wiping past a nose 168 on the detent.
