    Abstract: 588,491. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. (International Business Machines Corporation). Feb. 22, 1945, No. 4516. [Class 106 (i)] A record card controlled accounting machine comprises a pair of card magazines each associated with feeding means for feeding cards from the related magazine through a related sensing means, high, equal, low comparing means for comparing group data of two cards in the two sensing means respectively and causing one or the other feeding means to operate accordingly, and an accumulator controlled by both sensing devices and the comparing means. In the embodiment described, successive master cards in a magazine 13, Fig. 1, contain data as follows : name, street, city, balance, instalment payment. Detail cards in the other magazine 18 contain details of purchases and goods returned. All cards contain the customer's surname which controls the comparing means. Cards read simultaneously at brushes M1 and D1 set up a comparing network, Fig. 17c, which determines which of the two feeding means shall continue to operate. Cams C12 ... 17 are timed to close contacts R1a ... 6a &c. so that impulses received in wires 185 and 186 from the master and detail card reading brushes respectively serve to energize relays R1M ... R6M, R1D ... R6D, &c. in accordance with a code. A test impulse is then passed through the network controlled by these relays (e.g. note heavy line in Fig. 17c) and energizes one of three relays LD, E and HD, according to whether the comparison reveals a low detail, equal, or high detail condition. The energized relay then controls the circuits including clutch-controlling magnets whereby either the shaft driving the master feed rollers 15, Fig. 1, or the shaft driving the detail feed rollers 20 is coupled with the constantly rotating shaft driving feed rollers 48. Printing mechanism. The secondary sensing brushes M2, D2, Fig. 1, control known printing mechanism, Fig. 8. The energization of a magnet 95 pulls a call wire 97 which rocks a bell-crank 100 and releases a clutch arm 89 to engage a dog 91 with the appropriate notch of a rotating wheel 87. Thus the print wheel 92 is driven through an intermediate gear 93 and continues to rotate until the engagement of a second clutch 111, whereby cam means 109 rock the three-armed member 108 carrying the print wheel and engage the latter with the platen, the rolling of the print wheel 92 over the intermediate gear 93 serving to bring the type squarely against the platen. The engagement of the second clutch 111 is controlled either by the sensing of a second hole in the card (i.e. when alphabetical data is being sensed) or, in the case of numerical data, by a cam 114 which rocks a lever 115 and, through a link 117 rocks an interposer 118 to bring its opposite end into engagement with a depending arm 113 of a bell-crank 112 controlling the clutch 111. At a predetermined time in the machine cycle, the cam followers 120, on which the interposers 118 are pivoted, move into a lower part of the cam and those interposers which have been positioned push the arms 113 and so release the clutches. The alphabetical printing is performed before this; a camcontrolled rod 101, together with the call wire 97, is lowered after the sensing of the first perforations and a second energization of the magnet 95 at the " O," " X " or " R " position causes the call wire 97 to rock the arm 113 and so actuate the printing mechanism at the time the appropriate letter is opposite the platen. Four pockets P1 ... P4, Fig. 1, are provided for receiving the cards which have passed through the machine. Pocket P1 is for detail cards which are to be kept separate ; pocket P2 may receive detail or master cards, or both ; pockets P3 and P4 are adapted to receive master cards only. Flexible leaves 66, Figs. and 7, serve to guide the cards to the various pockets, the leaves being positioned by L-shaped members 71, 71a which are controlled by magnets S1, S3, S4 energized by the sensing of perforations in the cards. Energization of magnet S4, for example, frees the armature and latchplate 68 from the member 71, and a spring 75 causes the member to press down the leaf upon which it rests and so guide the card over instead of under this leaf. The arrangement of the controlled leaves 63, 64, 65 is shown in Fig. 7. The accumulator, Fig. 10, is of known type in which a ratchet, normally held out of engagement with a complementary ratchet-wheel by leaf springs, is pressed into engagement by the sensing of a numeral in the card to drive the accumulator, a corresponding amount. In the case of negative amounts, the " nines " complement is added into the accumulator by engaging the ratchets at the beginning of the numeral sensing period and disengaging them upon sensing a perforation. A bevelled wheel 150 on a bell-crank 151 serves to cam the ratchets into engagement when the energization of a magnet 153 pulls its armature 152 out of engagement with the bell-crank 151. The energization of a subtract magnet 165 releases a lever 166 for anticlockwise rotation and a pin 168 on this lever engages and restores the bell-crank lever 151. The transfer mechanism comprises a cam 148 which co-operates with a lever 162 which positions a blade 159 in relation to contacts 160, 161. The contacts form part of a network, Fig. 17b, for carrying and adding in the fugitive one." The reading of detail brushes D1 and D2 control a second (known) comparing mechanism in which a relay GC, Fig. 17b, is energized if there is disagreement between the two readings. Specifications 422,143 and 523,652 are referred to.

    Abstract: 589,006. Calculating - apparatus. BRITISH TABULATING MACHINE CO., Ltd. March 14, 1945, No. 6404. Convention date, March 15, 1944. [Class 106 (i)] A device for obtaining the positive algebraic sum of a plurality of numbers comprises an adding network (Fig. 5e and part 5c), having a set of contacts interconnected between input and output wires in accordance with the table of addition of any two digits, a relay totatiser (Fig. 5c) comprising a set of magnets for each denomination of a number, means for connecting the set of magnets for a denomination to the output wires, means for adjusting the set of contacts of the network to represent a digit, means (Fig. 5f) for setting up a second digit on a group of wires, and for connecting the input wires to the set-up of the second digit, whereby current directed through the network to the totaliser magnets energizes a magnet or magnets of the set to represent the units digit of the sum of the first and second digit. A known type of punching machine is adapted to control the entry of data into the adding device, while corresponding numbers are punched, digit by digit in descending order, in a plurality of fields A, B, C, of a record card 10, Fig. 2. Corresponding denominations in each field are related to a common column selecting'relay (e.g. 4C for " thousands," Fig. 5b), and this relay is energized when a brush 36, moving with the carriage of the punching machine, connects a common strip 38 with the appropriate contact 37 plugged to the relay socket 43. Energization of relay 4C closes two contacts 4Ca, 4Cb, Fig. 5a, in the " thousands " section of a network in which contacts A4a, A4b, ACa ... etc. are controlled by relays Al ... A5, AC, Fig. 5c, in the " thousands " section of the totaliser. By this network, the value represented in the thousands order of the totaliser, on relays A1 ... A5, AC (numbers 6 to 9 being represented as 5 + ... ) is reproduced in a set of relays OP ... 5P, Fig. 5b, the " thousands " order of the totaliser then being cleared. The relays OP ... 5P control contacts in an adding network, Fig. 5e and top L.H. of Fig. 5c, whereby the " thousands " digit, extracted from the totaliser, is added to the " thousands " digit of the number being entered and punched. The depression of the appropriate key, Fig. 5f, energizes a punch selector magnet 19, which pulls down the corresponding key lever of the punching machine and this causes the perforation of the card in known manner. Also, a corresponding relay R20 closes its contacts R20a and a circuit is completed through one of the wires 60 to the adding network, Fig. 5e and 5c. The output wire or wires 61 ... 67 of this network complete the circuits of totalizer relays in the " thousnads " order representing the units digit of the sum of the two digits which have been added. A carry from one denomination to the next is represented by the energization of a special relay AC in the higher denomination, and where the higher denomination already contains a " 9 " (represented by the energization of relays A4 and A5) contacts A4e, A5e are both closed and the circuit to the A.C. relay continues to the next higher denomination to energize a further A.C. relay. The subtraction of a number from the total is accomplished by closing a switch 75, Fig. 5e, whereby relay S is energized to transfer contacts in the network, which now causes the incoming digit to be entered as the nines complement. The " fugitive one " is added into the units order when a transfer from the " tens of thousands order causes the energization of a relay CS. This relay closes the circuit to an A.C. relay in the units order. When the settings of the totaliser relays are transferred to relays OP ... 5P, by the network of Fig. 5a, the A.C. relays control contacts in this network which add in the carried " 1 ". The 'total of the entered numbers is punched on the card, when switches 56, Fig. 5b, and 81, Fig. 5f, are closed, a circuit being completed through a network, Fig. 5f, controlled by relays 5P ... 1P, whereby an impulse passes to the punch selector magnet 19, representing the " tens of thousands " digit of the total. the carriage then steps on to the next lower denomination and so on.
