Abstract: 380,612. Statistical apparatus. ADREMA MASCHINENBAUGES., 62, Alt Moabit, Berlin. Sept. 30, 1931, No. 27259. Convention date, Dec. 6, 1930. [Class 106 (i).] An address-printing machine is combined with a calculating machine for accumulating the amounts represented by projections, perforations, &c. on the printing plates. The plates co-operate with a multiple switch comprising sets of selector switches in circuit with electromagnets adapted to control the keys of the calculating machine. The circuit may include a set of relays so as to reduce the number of selector switches required to operate a given number of electromagnets. The apparatus, as shown in Fig. 1, comprises an address-printing unit A with a multiple switch unit W, a calculating machine B, and a set of interconnected relays C. Printing unit. This unit in addition to the multiple switch W, Fig. 6, is provided with a main switch HS which is closed automatically by the selected printing plate and with a controlling electromagnet StM operated by the selector switch elements w1 .. w8 which control the skipping of the printing-plates as determined by the setting of the hand-switches h1 .. h8. The electromagnet StM co-operates with a switch ZS in circuit with a master switch MS actuated by the operating mechanism of the printing unit and with a relay HRI controlling a switch S1 in the negative lead 72. The multiple switch comprises other elements w9 .. w30 some of which are connected to the relay set and others to the electromagnets 47, 47<1> of the keyboard of the calculating machine. The master switch MS is operated in unison with the printing member and co-operates with three contact strips 73, 74, 75 in circuit with the switch contact ZS and an electromagnet VM for effecting a shift of the keyboard electromagnets. Relay unit. The set C comprises four banks each including five relays R1 .. R5, Fig. 6, of which the relays R1, R2 control double contacts k1, k<1>1, and k2, k<1>2. The contacts k1, k2 are connected by a wire 79 and the contacts k<1>1, k<1>2 by a wire 80. The contacts k1, k2 also co-operate with fixed contacts 81 .. 84, as shown. The other relays R3, R4, R5 control switches 85, 86, 87 each with three contacts connected to the corresponding electromagnets 47 of the keyboard. One terminal of each relay is connected to the negative lead 88, the other terminal of the relays R1, R2 is connected to appropriate elements of the multiple switch W, that of the other relays R3, R4, R5 to the contacts 81, 82, and a contact co-operating with the contact k<1>2 respectively. The contacts 83, 84 and the mating contact of contact k<1>1 are connected to the positive lead 89. Additional relays HRII, HRIII are provided to control switches SII, SIII to operate electromagnets M, VM, controlling the movement of the carriage supporting the keyboard electromagnets and the denominational selecting position thereof. In a modification as shown in Fig. 8 the relay set C may be dispensed with and the multiple switch elements be connected to the keyboard electromagnets. With the switch X closed all printing plates will be used and the amounts registered. Calculating machine unit. This machine may be of known type and provided with uprights 43, Fig. 2, connected by side and transverse members 44. The inner edges of the uprights are engaged by rollers 42 carried on a frame composed of transverse members 41<1> and side members 41<11>. The side members support pairs of rollers 46 mounted on a carriage constituted by front and rear members and a bridge 66 on which is mounted the electromagnets 47, 47<1> the movable cores of which co-operate with the keys 50 of the calculating machine B. The carriage frame is held in its raised position by springs 62 each of which is secured at one end to the fixed transverse member 44 and at the other end is connected to one of a pair of links 59 pivoted to the carriage-supporting frame 41<1>, 41<11> and to bell-crank levers connected by a rod 63 with limiting stops 60. The lowering of the carriage frame to cause depression of the keys is effected by the excitation of electromagnets M the armatures of which are connected by links 55 to the carriage frame. If it is desired to shift the carriage so that the value represented thereon is registered as ten times the amount the electromagnet VM is energized before the electromagnet M so as to cause its armature to turn the shaft 64 and a carriage-shifting lever 51 forked to engage a pin 45<11> on a bar 45<1> secured to the carriage. The lever 51 is movable between stops 54, 541. A single electromagnet 47<1> is provided in the second decimal place above the " 5 " key. Printing plates. The plate as shown in Fig. 7 is provided with a set of projections 69 to co-operate with the multiple switch elements. The plate shown has projections representing the classification number 135, and amount projections representing the value 741À05. The heavy lines in the circuit diagram, Fig. 6, indicate the circuits concerned in calculating the amount referred to and the Specification describes the carrying out of the process.
