  • Macln'nes operating on this principle comprise a large number of printing wheels disposed side-by-side and which can simultaneously print line-by-line, at the rate of several hundred lines per minute, data which are transmitted to the machine by analysing means adapted to read punched cards or record tapes, which means transmit the said data synchronously with the mechanisms of the machine.
  • Machines called translating or interpreting machines are also known, which print on record cards, characters or signs corresponding to data analysed in various columns of the said record cards.
  • Machines of this type are so designed as to be able simultaneously to translate the data recorded in all, or a large number of, the columns of a record card.

The numerical values are recorded in a column by a single perforation formed in the numerical position corresponding to the recorded digit. The alphabetical indications are recorded by the combination in a column of two perforations, one of which has the position 9,8, or 7, while the other is located in one of the other positions of the column, in accordance with one of the code combinations hereinafter indicated.
  • the machine is provided with a row of eleven analysing brushes ( Figure 5). These eleven brushes are disposed ( Figures 7 and 15a) in the positions 85-11, 85-0, 85-1, 85-2, to 85-9 for analysing respectively the recording positions 11, 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 of a column of a card advanced through the machine for translation.
  • the decoding of the analysed combinations of perforations is effected in principle by the known relay contact tree arrangement system but the mere decoding by this process of a code comprising eleven positions would involve the use of a prohibitive number of relays.

  • the starting of the machine comprises a preparatory phase which is necessary for applying voltage to the electric circuits and the heating of a thermionic tube.
  • the contact RTla ( Figure 15a) is closed and establishes a circuit which lights a pilot lamp 28 visible on the front of the machine ( Figures 1 and 2b).
  • the voltage +275 v. can be applied later to the anode of the tube TD and enables this tube to operate, its filament being hot, under the control of pulses.
  • the electromagnet 70 ( Figures 15a and 2b) is energised when the machine is inoperative by the following circuit: +48 v., line 100, line 101, closed contact 121a, electromagnet 70 to earth.
  • the energised electromagnets 70 pivots the member 71 ( Figure 2b), which maintains the cards 20 in the raised position out of the path of the feed knife 67.

It will be seen that, before the time lag determined by the slow-acting relay RTl, the contact of the slow-acting relay RTlb shunts the contact 121a and that the opening of the latter contact does not deenergise the electromagnet 70, as long as the contact RTlb of the slow-acting relay is not open.
  • a so-called full-compartment contact CP Disposed in series with the contact CM, which is closed by the presence of cards in the magazine 21, is a so-called full-compartment contact CP ( Figures and 15a).
  • This contact is automatically opened, as will hereinafter be described, to stop the card feed as soon as the receiving compartment 23 is full.
  • a card extracted from the magazine 21 by the knife 67 is fed by the rollers 52, 53, 51 and 54 on to the analysing and printing section (line 77 of Figure 5), whereby a so-called card lever contact LC is closed (Figure 15a).
  • a cam contact CA3 ( Figures 14 and 15a) is closed.
  • a circuit is established as follows: +48 v., line 100, line 103, contact CA3, contact LC, line 104, relay 110 and earth.
  • the energised relay 110 closes the contact 110a, which is in series with a cam contact CA4.
  • the cam contact CA4 is closed ( Figure 13) before the contact CA3 is opened, and the relay 110 is therefore maintained in the energised condition by the contact CA4.
  • the voltage applied to the relay 110 is also applied to a cam contact CB5 ( Figure 14a), which is called the column reading contact.
  • This contact applies voltage to the contact plate 116 ( Figures 5, 7 and 15a).
  • One card to be translated being, for example, the card illustrated in fragmentary form in Figure 8, which bears the indication MACHINES BULL 94, the recording of the letter M is represented in accordance with the above-mentioned code, in the first column of the card by the perforations 2 and. 8.

  • the relays R7, R5, R4 and R1 are maintained energised by the line 120 through the rectifier elements ER7, ERS, ER4 and ERl respectively. It should be noted that the beginning of the first column cycle (see Figs. 14a, 14b) coincides with the beginning of one card cycle or point 0 of the diagram of Fig. 13.
  • the contact tree arrangements controlled by relays RDl to RD7 includes actually two of them, of which the first is controlled by the relays RD1 and RDZ and the second by the relays RD3, RD4, RDS, RD6 and RD7.
  • the inputs of the contacts of the first tree arrangement can be sequentially connected (Figure 15b) to the output EP of the second tree arrangement by a group of cam contacts CB1, CB2, CB3 and CB4, of which the closing times are indicated in the diagram of Figures 141: and 14b.
  • a card column is shifted with a continuous movement into the analysing and printing position of the machine (line 7-7 of Figure 5) by a distance equal to the width allocated to a column on the card, and the printing of a given character is carried out by the actuation of the hammer 111 ( Figure 7) of a striking mechanism 112 ( Figures 5 and 7) at a given instant in a column cycle, in accordance with the character to be printed.
  • a cam contact CB6 ( Figures 14a and 15b) is closed and applies to a condenser 91 the direct voltage of 275 v. through a resistance 91 which limits the strength of the charging current of the said condenser.
  • the inked ribbon 96 supported by the guide 97 is disposed between the card C and the printing wheel 37.
  • the actuation of the hammer 111 prints on the card C the character of the wheel 37 which is opposite the hammer at this instant. Since the printing of the characters takes place during the displacement of the card, the type characters are disposed on the wheel in the form of a helix whose pitch is equal to the pitch P of the columns on the record card, as can be seen on Fig. 10.
  • the arrangement of the type characters on the wheel and the instant when, in a column cycle, the various character types of the printing wheel travel past the printing position are indicated in detail in the diagram of Figures 14a and 14b.
  • the analysis of the card perforations 2 and 8 has energised the relays RD7 and RDS, RD4 and RD1 and that the contact RDla which has rocked establishes communication between the line 107 and the contact RDZb connected (in the inoperatime position) with the cam contact CB3.
  • the line 108 communicates through the contact RD3a (in the inoperative position) with the contact 'RD4a (rocked) which, through the contact RDSb (rocked), communicates with the coil 785 of the magnetic distributor.
  • the pulse induced in the coil 785 of the distributor can be transmitted to the control grid 94 of the triggering valve TD through the following circuit: 10 v., coil 78-5, contact RDSb (rocked), contact RD4a (rocked) contact RD3a (inoperative), contact CB3 (closed), contact RDZb (inoperative), contact RDla (rocked), line 107, control grid 94 of the triggering valve TD and resistance 109 connected to 10 v.
  • the triggering valve TD is fired by the pulse transmitted to its control grid, and the condenser 90 discharges rapidly into the coil 93 of the striking device.
  • the hammer 111 is actuated at the point C3-5 indicated in the diagram of Figure 14b.
  • the coil 93 and the condenser 90 are so designed that the discharge of the condenser takes place through the said coil with damped oscillations.
  • the valve TD which controls the discharge of the condenser also performs a rectifying function and only the first halfcycle of the oscillation can pass into the coil 93.
  • the energy thus transmitted to the electromagnet actuating the striker hammer 111 can be very exactly defined by the charge imparted to the condenser 90.
  • the striker hammer 111 thus actuated is thrown ( Figure 7) against the assembly comprising the card C and the carbon ribbon 96 and the printing wheel 37, and then rebounds to the rear position where it is maintained by the action of the springs 113 and 114.
  • the contact CB7 ( Figures 14b and 15a) is opened, whereby the relays R1 to R7 and RD1 to RD7 are de-energised and the holding contacts Rla to R711 are opened.
  • the cam contact CB6 is again closed from C0 to C0-6 ( Figure 14a) for recharging the condenser 90.
  • the diagram of Figure 14a indicates by the line B8 the time during which, in the travel of a card column past the analysing brushes 85, one or more of these brushes can make contact, at each column cycle, with the contact plate 116 through perforations in the card, approximately from the point C0-3 to the point C22.
  • the closing of the cam contact CB ( Figures 14a and 15a) from the point C0-6 to the point C21 causes current to be fed to the plate 116 to permit the analysing of the perforations of a column to be translated.

  • Cam contacts CA5, CA6, CA7 and CA8 are arranged tobe opened in a card cycle at instants corresponding to columns or groups of columns which it may be desired to prevent from being translated. It is obvious that, with the detachable link 86 withdrawn and the contacts CA5, CA6, CA7 and CA8 connected in series, all the suppressions of translation of the columns which are produced by the opening of each of the said contacts will be rendered effective.
  • Detach- 10 able links disposed between various terminals of the said cam contacts permit various combinations of translation suppression.
  • the card cycles and the column cycles in the card cycles succeed one another indefinitely as long as there are cards to be translated in the magazine 21 of the machine.
  • Stopping of the translation i.e. stopping of the feeding of cards to be translated, may result from various causes. It has been stated at the beginning of the present descrip tion that the introduction of cards into the magazine 21 results in closure of a contact CM ( Figure 15a). On the other hand, when the last card to be translated in a stack of cards has left the magazine, this contact is automatically opened and, by virtue of the known arrangement, this results in stopping of the machine under the conditions which will be described elsewhere.
  • the contact CP called the full-compartment contact ( Figure 15a) is controlled by a lever 24 ( Figures 2a and 5). When this lever is lowered under the weight of a sufiicient number of cards ( Figure 2a), the contact CP is opened, whereby the machine is stopped.
  • the contact 27 .for stopping the advance of cards is in series with the contacts CM and CP ( Figure 15a).
