Description

There are accounting machines known in which an adding or calculating machine is connected to a plurality of balance memories in such a way that the balance of each memory transferred to the summation of the adding or calculating machine, there around the result the last calculations relating to the account of the selected memory can be changed and transferred back to the memory as a new balance.

In order to increase the operating speed of the accounting machine, according to of the invention by the one-time adjustment of an electrical control circuit Distributor successively transferring the balance from the selected memory the keyboard of the adding or calculating machine, the transfer of the balance to the totalizer the adding or calculating machine and the transfer of the new balance back to the memory and, if necessary, before the Transfer of the old balance to the sum of the adding or calculating machine, expediently during his entry on the keys of the adding or calculating machine, the transfer of the value already on the total to the keys of one Typewriter done.

A major advantage of the new bookkeeping machine is that the result of the Posting operations that are to change a balance, initially only visible and for occurs in a printable manner in the sums of the adding or calculating machine. Further the new machine enables a balance to be transferred using conventional tens transfer devices to a total that does not have to be set to zero beforehand because the setting of the balance is done using the setting keys of the adding or calculating machine, whereupon the transfer of the balance to the totalizer through the mechanism of the machine is carried out by itself. Finally, the new bookkeeping machine also allows Retransmission of the new balance without the wheels of the totalizing unit approaching zero which would cause the value they displayed to be lost.

simultaneous work of a calculating machine MC or the like (Fig. 3), a typewriter ME (Fig. 2) and a total or several total works Ji I, .1 / 11 ... (Fig. ι) possible. When the calculating machine has carried out a calculation, the result is transferred to the typewriter ^; wear in which it is printed. At the same time, the total from previous calculations in the totalizing unit connected to the calculating machine is transferred to the keyboard of the calculating machine and added to the number just transferred to the typewriter. The result obtained in this way is then re-entered into the totalizing unit connected to the calculating machine. If you connect a calculating machine with several sums, you can transfer the additions to one or the other sums, depending on the requirements.

In order to transfer a result from the result counter wheels R of the calculating machine either to the typewriter ME or to one of the sum units M I, M II ..., for each of the result counter wheels R _u , R _b , R _c . 6 and 7 arranged switches shown in detail. On this axis 1 of each resultant stitching wheel is a near its circumference with contact pins P ₀ , P _{1 of} different lengths. . . P ₉ provided disc 2 wedged. A pivotable lever 3 under the action of a spring 4 is usually held in place by a locking bar 5 which is common to all levers 3 and which can be raised by an electromagnet ER so that the levers 3 can swing back and forth. This movement of a lever 3 is stopped when its end 6 of the disc 2 of the corresponding Resultatzählwerksrades R comes into contact with one of the contact pins F _0, F ₁ ... F. ₉ The size of this movement changes according to the position of the result counter wheel R, ie according to the number to which it is set. Contact springs 7 arranged at the other end of the lever 3 then close that breaker R Ia ₀ , RIa ₁ ..., RIIb ₀ , RII b _x . . ., which corresponds to the set number. These breakers are switched in circuits (ι Fig. And 2) either to influence the typewriter keys serving electromagnets E _0, E _1. .. or to electromagnets EG ₁ , EC ₁ ... provided for controlling the contact pins of block 10 (FIGS. 8, 9) or finally to electromagnets EA ₀ , EA ₁ intended to influence the computing machine keys. . ., EB ₀ , EB ₁ ... etc. (Fig. I) are connected.

For the sums M I, MII ... and the typewriter ME auxiliary magnets S (Fig. 1) and auxiliary magnets 9 are provided for the calculating machine MC, which, when excited, act on levers H ₁₁ and g _a , through which all Electromagnets EG or EA, EB are connected in a row to the corresponding circuit. All electromagnets are normally isolated to avoid branch currents.

Each sum work MI, MII. . . shows a block 10 (Fig. 8, y), which by means of a double armature switching device 1 [ a gradual movement in one direction or the other can be given.

The block 10 is arranged displaceably on rails 13 and has rows of contact pins G ^ i ₀ , GA ₁ . . .. GB ₀ , GB ₁ . .. , one of which is shown in Fig. 8a. Each contact pin drawn into the block 10 in the idle state can be activated by a fixed electromagnet EG ₀ , EG ₁ , EG ₂ . . . be pushed out of the block 10 a little. The different rows of pins correspond to different orders of units, and in each row each pin corresponds to one of the first ten digits. Furthermore, a series of breakers is I ₀ , I ₁ , I ₂ . . . (Fig. 10) arranged, which are closed by the pushed out of the block 10 contact pins when the block 10 moves to the right. In addition, an inclined surface 33 is firmly arranged, which presses the contact pins back into the block.

The double armature switching device 11 consists of two shift teeth 12 and I2 "(Fig. 9 and 11), of which one, namely I2 _U , only one shifting movement to the top left, and the other, 12, only one to the top right can perform <oo. For this purpose, each switching tooth 12 or 12 ^ is provided with two obliquely arranged slots 30 ,, and hung with these on guide pins 30, which in turn are attached to a base 31 pivotable about a fixed, horizontal axis 14. The pivotable arrangement of the shift teeth 12 and I2 "is necessary to enable them to come out of the tooth gaps of the block 10 after the shift. The switching tooth 12 is moved by the electromagnet EN ₁ and the switching tooth I2 _a by the electromagnet EN ₂ .

The various circuits, the calculation engine MC typewritten ME and the various sum works MI, Λ / ΙΙ ... connect be switched from an \ ^r issuer D from that in detail in FIGS. 4 and 5 and schematically in Figure . ι is shown. This distributor has a number of disks 15 each provided with a cam 16 on their circumference.

The cams 16 cause the next

• The conditions described below and, in the order given, the closure of a number of contacts C. The distributor is rotated by means of a key T , the shaft of which is designed as a rack 17 which meshes with a toothed wheel 18 wedged on the axis 19 of the discs 15 .

The mode of operation of the device is described with reference to FIG. 1, with particular reference to the fact that only a few circuits of each circuit group are shown. Of the electromagnets EA ₀ , EA ₁ ... , EB ₀ , EB ₁ ... etc.

the keys of the calculator MC associated circuits are z. B. only the two circuits corresponding to the digits 0 and 1 are shown, but it goes without saying that there are ten identical circuits. The same should be noted with regard to the circuits for the typewriter ME and for the various totalizers M I, MII ... The circuits in question are controlled by a certain number of devices, such as .Stromwender, interrupter, etc., which have not yet been described, but whose task arises in the course of the description of the operation of the device.

The machine works as follows:

a) During the forward gear of the distributor D (Fig. 4, 5), the result of the just executed in the calculating machine

Transferring the invoice to the typewriter and at the same time those from previous invoices Brought in the sum standing sum in the keyboard of the calculating machine.

b) During the reverse gear of the distributor and after the addition of the result of the calculation that has just ended and the sum transferred from the totalizer to the calculator's keyboard, this new sum is transferred back to the totalizer.

The details of these operations are as follows:

It is initially assumed that the calculating machine MC is only connected to the first summation unit MI . The breaker 20; (Fig. 1) is closed and the breaker 2o _w open. It is also assumed that several calculations have already been carried out and a total is already displayed in the total, ie that certain contact pins GA ₀ , GA ₁ ..., GB ₀ , GB ₁ ... (Fig. 8) are highlighted.

The calculating machine carries out a new calculation, the result of which is indicated by the result counter wheels R. Then the operator presses the button T (Fig. 4, 5) of the distributor D down. The movement of the distributor closes various electrical circuits and controls various parts of the machines as follows: first, contact C ₁ (Fig. 1) closes, causing the following operations:

a) the excitation of the coil 21, by means of which the commutator 22 is brought into the position shown with full lines;

b) the energization of the coil 23, which causes the closure of the multiple breaker 24, which in turn switches on the various rows of electromagnets EA, EB, EC ... of the calculating machine;

c) the excitation of the coil 25, by means of which the commutator 26 is brought into contact with the contact 27, as a result of which the various breakers I ₀ , I ₁ (cf. also FIGS. 8, 10j of the totalizer MI are switched on;

d) the excitation of the coil 28, by which the interrupter 29 is closed, which switches on the electromagnets E ₀ , E ₁ , E ₂ ... of the typewriter.

Then the contact C ₂ closes, but plays no role while the distributor D is running. "

The contact C ₃ switches on the electromagnet EN ₁ (Fig. 9), by means of which the block 10 is switched to the right by one more tooth.

The contact C _{4 then} closes and holds the electromagnet ER fFig for the entire duration of the closure. 1, 6, 7 ) in the position in which it releases the contacts of the result counter wheels R of the calculating machine.

The contact C _{0 then} closes, whereby the passage into the row of electromagnets EA of the calculating machine is enabled by the excitation of the corresponding electromagnet 9. In this row, that electromagnet is excited which corresponds to the breaker I ₀ , I ₁ , L ₂ ... of the totalizer, which is closed by the contact pin G (Fig. 8) pushed out of the row of that contact pin row which is at that moment this interrupter row is opposite. The excitation of this electromagnet causes the corresponding key of the calculating machine to be depressed. The totalizer MI has now transferred the first digit of the total in it to the keyboard of the calculating machine.

The contact C _{0 also} switches on the contact of the first result counter wheel R _tl , so that the one of the breakers R Ia _{0 , RIa 1} ..., which is due to the position of the

Result counter wheel is closed, causing the excitation of one of the electromagnets E ₀ , -E ₁ ... of the typewriter; this electromagnet then causes the corresponding number key on the typewriter to move. This then prints the digit transmitted by the first result counter wheel R _a , ie the first digit of the result of the calculation just completed in the calculating machine is transferred to the typewriter. The contact C ^, which now closes, energizes the electromagnet EN ₁ , so that the block io of the sum mechanism M I is advanced by one more tooth. The contact C ₆ plays the same role as the contact C _a , ie it simultaneously causes the actuation of a calculator key in the row EB and the actuation of one of the typewriter keys. The contacts C ₅ , so C ₆ ... etc. then play the same role as the contact C ₃ , while the contacts C _1. , C ₁ , ... etc. assume the same role as the contact C _11. In this way one obtains the total entry of the result of the calculating machine in the typewriter and the entry of the total in the sum unit in the calculating machine.

If the contact C _{4 is} interrupted, the magnet ER is de-energized and the bar 5 (Fig. 6, 7) opens the contacts RIa. At this moment the contact C ₈ closes and switches on the electromagnet 30, which actuates the usual adding button of the calculating machine. By pressing this button, the result of the previous calculation and the sum just transferred are added.

Contact C ₉ now closes and causes the following processes:

a) The commutator 22 is brought into the position shown with dotted lines by the coil 2i _a.

b) The multiple interrupter 24 is opened by the coil 2 $ _u. c) By means of the coil 25 ,, the commutator 26 is _{brought into contact with the contact block 2 / a} , whereby the electromagnets EG ₀ , EG ₁ . . . of the totalizer HI must be switched on.

d) The coil 28 ,, is the interrupter 29 opened so that the typewriter electromagnets are switched off.

_{Contact C 8} does not play a role during the return of the distributor. Contact C ₄ , which now closes, plays the same role as when the distributor runs forward. Of the contacts C _e , Cj, C ₇ , which are not connected in the circuit diagram shown in Fig. 1, the contact C ₆ closes first, which by means of the coil EN _2, the displacement of the block 10 (Fig. 9) of the totalizer by one tooth, but this time to the left.

Now the contact C _c closes and switches on the contacts of the result counter wheels R _c , whereby that of the electromagnets EG ₀ , EG ₁ ... is excited which corresponds to the number indicated on the result counter wheel, so that the corresponding contact pin in the block 10 (Fig. 8) is brought into an advanced position. In other words, this means that the digit in question is entered in a row of contact pins in the totalizer MI , which is one of the digits of the sum that has just been determined in the calculating machine. The processes then follow one another, and those in the result counter wheels R _a , R _b . . . standing sum is transferred to the totals.

When the contact C _s closes, the coil 31 is energized and actuates the zeroing lever of the result counter wheels R _a , R _b (Fig. 3), which, as usual, is attached to the calculating machine. The contact C ₁ leads the commutator 22 back to the position shown in full lines.

When the calculating machine has carried out a new calculation, you can enter the result of this calculation in the typewriter in the same way, by pressing the key T (Fig. 4, 5) of distributor D again , and transfer the information contained in the totalizer M I Sum in the calculating machine, the addition of this sum and the result of the above-mentioned calculation and the transfer of this new sum back into the sum unit M I.

Of course, you can use the same calculating machine with any number of summaries M I, M II, M III ... etc. and connect them to the machine by closing breakers 20 _/; 2o _H ... 105 ■ stop.

In addition, the application of the invention to the connection of a calculating machine and a typewriter is only given as an example. The invention would be applicable under the same conditions to a calculating machine that is not connected to a typewriter. In this application, the sum entered by the multiplier would be entered in the calculating machine when the distributor D runs forwards, while the sum obtained in this way would be transferred back to the totalizer when running backwards.

Such an explanation is shown in FIGS. 12 to 15 management form of the sum work shown. According to this embodiment, the

Contact pins GA, GB. .. instead of housed in a movable block in a fixed box io, in which they can move in a vertical direction.
All contact pins of the same row, that is to say all that correspond to the same order of units, e.g. B. all contact pins GA ₀ , GA ₁ ... GA ₃ , are stored in a displaceable selector strip BA moved by an electromagnet EA. On the other hand, each of the rows of contact pins corresponds to a control strip 6 ₀ , b _± ..., which is actuated by an electromagnet E ₀ , JS _{1 ....} As can be seen from Fig. 12, the contact pins are inclined in the usual state and in this position give way to the action of the control strips b ₀ , Ib ₁ ... If, on the other hand, all contact pins of the same order are brought into the vertical position by the action of the corresponding selector strip B and then the control strip b corresponding to a certain row is lowered by the action of the associated electromagnet ZT ₀ , E ₁ ... (Fig. 15) , then the control bar acts b ₀ , ^ ₁ ... on the vertical contact pins and presses them down. In Fig. 12, the contact pin of the row S is shown in this position. In other words, this means that the electromagnets EA, EB ... select the order of the units and are controlled from the distributor of the machine. The electromagnets E ₀ , E _1, on the other hand, select the number to be entered for each order of the units. These electromagnets are controlled by the result counter wheels of the calculating machine.

To return the contact pins from their working position to the rest position, For example, a liftable plate (not shown) arranged under the box 10 can be provided which pushes the contact pins upwards from below.

Each of the contact pins made of a conductive material receives current through the fixed lower guide plate 40 made of conductive material. On each contact pin there is a contact spring 41 which normally rests against an insulating piece 42 when the contact pin is in its inclined or rest position. On the other hand, when the contact pin is in a vertical, downwardly printed position, the spring 41 rests against a conductive piece 43 which is connected to the electromagnet located in the keyboard of the calculating machine, which is on the key corresponding to the contact pin (namely the same order of units and the same number ) acts. Each contact pin is also under the action of a spring 44 which keeps the contact spring 41 in contact with the contact piece 43, even if the corresponding selector strip 3 has returned to its rest position after it has depressed the contact pin in question. To the simultaneous excitation of the electromagnets EA, EB ... and the electromagnets E ₀ , E ₁ , a breaker 45 (Fig. 14) is built into the excitation circuit of the latter.This breaker 45 is normally open and is only closed by a flap 46 when one of the selector strips BA, BB ..., each of which has a stop serving at its end to move the flap 46, has completed its movement.

The mode of action of this totalizer is the same as the mode of action specified for the other exemplary embodiment. The electromagnets EA, EB. .. play the role of the electromagnets EN ₁ and EN ₂ in FIG. 9. The electromagnets Ea, Eb ... play the role of the electromagnets EG ₀ , EG ₁ ... in FIG. 8 and the breakers 41 controlled by each contact pin through 43 the role of breakers I in the same figure.
