Description

Alfred Krause in Neu Schönningstedt, Post Reinbek b. Hamburg. Account Corrent Calculator. The present invention is a novel Kdnto-Korrent calculating machine. Like others Such .Maschinen, the presently described is a connection of a Adding machine with an account device, d. H. a number of departments, Transfer the numbers calculated in the adding machine of your choice to the numbers can be. In such machines, the departments consist of rows arranged same Parts that represent the individual bodies of the Match number. Such parts are e.g. B. racks, gears or number rollers. The values of the individual digits of the number to be displayed are indicated by the respective The position of these parts in relation to their initial or zero position is indicated.

Compared to the already known such account corrent calculating machines the machine according to the present description has the advantage that it even with a number of a thousand and more departments, called accounts, handy for operation remains and their making and repairing damage does not affect the difficulties comes across with which other machines because of their different structure to knot to have.

An embodiment of the invention is shown in the drawings.

Fig. I shows three superimposed digits of an account balance with _ the box in which they are stored, in cross section.

Fig. 2 shows how the individual balances (departments) side by side are arranged in their box.

Fig.3 is a scheme to explain the process when transferring a Balances on the adding machine or on one of the account departments.

Figure 4 is a cross-section through the overall side view of a machine with a high number of accounts.

Fig. 5 is the front view of this machine.

Fig.6 is a section through the frame with the rod pusher and Fig. 7 is a view of this frame.

The bars indicating the value of the digits are i (Fig. I) connected to a driving hook 2, which is rotatable in the joint. 4. The rods i store 25 pieces each (corresponding to 25 accounts) in boxes 5 next to each other (Fig. 2). The distance from the center to the center of the bar is 3 to 4 mm. The to an account Corresponding poles lie on top of each other.

The rollers 7 of the locking lever engage in the recesses 6 of the racks i 8 a. The locking levers 8 have a U-shaped cross section, each enclosing a “rack” i and have their common pivot point in axis 9.

If you move a rack i, the locking lever 8 is by means of the roller 7 is raised. It rotates around axis 9. Its opposite end then press the lever io.

The lever io is rotatably mounted about the axis i i. At one end he carries a rail 12 which, when the lever io not straight through one of the locking levers 8 is raised, touches all locking levers 8 belonging to a box 5. The arm 13 of the lever io is made of non-conductive material and has a contact spring at its end 14. If a locking lever 8 is raised as a result of moving a rod i and thereby If the lever io moves, the contact spring 14 is pressed down onto the contacts 15 and 16 and a circuit is closed. When pushing the bar i then lowers the locking lever 8 again, as the roller 7 sinks into the closest recess 6, the lever io is pushed back by the spring 17 and the circuit is interrupted again.

A locking piece 18 is located in each box 5 above the locking levers 8 arranged to be rotatable about the pin i9, to turn at the given moment by means of the key 2o, which extends beyond a row of boxes 5, the rods i against unintentional To be able to secure moving (e.g. when dismantling for the purpose of repair).

The aforementioned contacts 15 and 16 are arranged in each box 5 and the individual contacts 15 are connected to one another. So are the contacts 16 connected to each other. The connection of the contacts 15 is through the line 187 continued up to one pole of a power source (Fig.3). The connections the contacts 16 are connected to the switch 188, the contacts 16 each according to its position with the electromagnet (or relay) igg or Zoo connects. As can be seen in Fig. 3, the electromagnets 199 and Zoo stand with the other pole the power supply source in connection. These magnets are used by means of a known (not shown) ratchet device the gears 25 by current connection to turn one tooth forwards or backwards.

The gears a5 are one with the individual number drums. known Adding machine coupled. The arrangement just described therefore gives the possibility of to cause rotation of the wheels 25 by moving the rods i, namely by repeatedly connecting and disconnecting contacts 15 and 16. Depending on whether the switch 188 supplies the current to the magnet ic) q or zoo, the corresponding Wheels 25 rotated in one direction or the other.

The rods i are pushed back and forth by the angle irons 21 and 22, which go beyond all accounts (departments). Isn't one of those Accounts (departments) switched on, the driver hooks 2 take the shown in Fig. I strongly drawn diagonal dividing line. The angles 21 and 22 can be used in this hall horizontally to the left and can be moved right without them the projections 3 of the driver hooks 2 can grasp. But now they have become one Account belonging to the carrier hook 2 always through. one belonging to this account Slide 28 connected to one another, so that when one of these slide '28 (Fig. 2) always all of the subordinate, i.e. belonging to one and the same account Driving hook 2 are raised, namely in the dash-dotted line in Fig. I horizontal position. If the angles 21 or 22 are now shifted, they capture the projections 3 and force the rods i to follow their movement.

So z. B. the angle 2i when moving to the left Position I in position II which is switched on by lifting the slide 28 Move rods i to the left. Depending on the position of the rods i are here the projections 3 are detected sooner or later. As soon as this occurs, will the locks 8 are raised, and what is already described is repeated Connecting and disconnecting the contacts 15 and 16, the continued rotation of the number drums Adding machine.

If the angles: 2i have reached position II, the Rods i in the position that corresponds to the zero position. The adding machine on the other hand will then have that number in its reader that was before the movement of the angle 21 from position I to position II was indicated by the rods i.

The return movement of the rods i takes place through the angle 22. For this purpose, the individual brackets 21 have electromagnets 62 at both ends which attract the brackets 22. One of the poles of the magnets 62 is connected by the line 201 to the corresponding contact spring 2o2. The gears 25 carry slip rings Zoo, which are attached to the gears 25 in an isolated manner. The contact springs 2o2 and 203 slide on these slip rings; they do not touch one another but are only connected to one another by the slip ring 204. At the point 2o5 the slip rings Zoo are interrupted. The slip rings 20 [are attached in such a way that, when the contact springs 2o2 and 203 are currently on the breaker points 2o5, the corresponding points in the counter of the adding machine indicate zero. In this position, the circuit supplied by the contact springs 202 and 203 and through the line toi the electromagnet 62 is interrupted.

The electromagnets 62 are also connected to the changeover switch 2o6. The changeover switches 2o6 and 188 are connected to one another by the member 207, so that the switches 2o6 and 188 cannot be adjusted independently of one another. The connection 207 carries two drivers 2o8 and 2o9, so that the connection 207 is shifted to the right or left by the movement of the angle 21.

If the angles: 2i reach position 2111, ie the position in which all racks i of a division are at zero, connection 207 is simultaneously pushed over to the left. In order to make this movement as short as possible, instead of moving the connection 207 directly by means of the driver 2o9, as indicated in FIG. 3, the connection 207 can also be moved in a known manner by triggering a lock by means of a spring tension. In this case, the tension spring would be tensioned again when the angle 21 goes back to the right and when the driver 208 is pushed away by moving the rod 207 to the right.

If the connection 207 is pushed to the left in one of the ways just described and this toggles the switches 188 and 2o6, the magnets 62 are supplied with current and, at the same time, the magnets 99 are switched off and the magnets 200 switched on, whereby the rotation of the wheels 205 is prepared in the opposite sense.

As already described, the bars are pushed back and forth i through the angle irons 21 and 22. The forty angles 21 of those described here ten-digit machine for a thousand accounts (departments) are used for this purpose Twenty each with their ends attached to the connecting pieces 23 (Fig. 6) and on connected to solid grids in this way. The resulting two grids will be moved back and forth by four spindles 24. Since the spindles 24 right and left-hand threads the grids will approach and move away from each other depending on the direction of rotation of the spindles 24.

A simultaneous and uniform turning of the four spindles 24, the spindles are linked by chains and sprockets. The drive the chain or one of the spindles 24 is done either by hand by crank or - by means of an electric motor with the interposition of a suitable translation.

The forty angles 22 are not connected to each other, but slide individually on the guide pin 26 and. here. Two of them each, i.e. H. in the Attached at the same height are connected to one another by springs 27.

Fig. 4 and 5 show the structure of the machine. Right and left of the free one Room 3o are ten pole boxes 5 on base boxes 29 arranged side by side and one behind the other on two floors. The lower Rows of boxes rest on the common base plate 31, the upper rows on the four pedestals 32. The bases are attached to the frame 33 and to the side supports 34. The Frames 33 are also connected by walls 35 which form the upper part of the support 34 correspond. On the frame 33 is the board 36 that the adding machine wearing.

The U-shaped connections 37 carry the key supports 38 with levers 39. These levers are moved by buttons 40 and push rods 41. The push rods 41 are passed through the cover 42. The connection from the levers 39 to the slides 28 takes place in the upper rows of accounts by the train connections 43 and 44, at the lower rows by the pull connections 45 and 46 and by the levers, pull wires and train connections 47, 48 and 49.

The arrangement of the accounts in different one above the other and next to one another Rows significantly reduces the space it takes up. The thousand accounts together with the common adder and with the free space under the adder for the knees of the operator and for the possible installation of an electric motor, do not require more space than an ordinary desk with side compartments takes up. The two outermost accounts (departments) are approximately 1.4 m apart.

To make a repair inside the pole boxes, secure you first use the key 2o (Fig. i) and the locks i8 to move the rods z against forcible displacement. Then you draw the row of boxes in question, in that one has perceived damage.

To facilitate this pulling out, the pull connections 43, 44 and 49 the hook shape shown in Fig. I. The guide 52 prevents evasion .this hook.

If a key button 4o is pressed down and thus a slider 28 is raised, the bar 53 (Fig. I), -the previously snapped into the gap 54 of the Slider 28 engaged, now in the gap 55, pulled by the spring 56. The Bar 53 extends beyond all accounts. At its ends it has levers 57, which rotate around the pins 58. The holder 59 is connected to the angles 21. It carries, rotatable about the pin 6o, the driver 61. When returning, the angle 21 from position II to position I, the driver 61 lifts the lever 57 and rotates the bar 53. The slide 28 falls into its lower position at this moment back and the strip 53 then snaps back into the gap 54. At the next Movement of the holder 59 to the left, the driver 61 has no influence on the lever 57.

The mode of operation of the machine is now to be seen in the following on the basis of a Numbers = to be described as an example.

Assume that the number 94 is to be transferred to an account that is still at zero be transmitted. This number can naturally, depending on the intended use of the Machine, both an amount of money and any other value that I mean want to hold onto and from which a change by enlarging in the foreseeable future or reduction by a certain amount is to be expected, but then his Setting in an adding machine that takes as little time and effort as possible is desirable. So it is z. B. desirable for statistical purposes if the magazine and receipts of the materials of a factory are booked according to quantities.

In order to post the number 94 chosen for the example, first depressed the button 4o (fig. 4) corresponding to the account in question. the Downward movement of this key is in this case by the associated lever 39 in upward movement converted and transferred to the corresponding slide 28, whereby the associated Driving hook 2 are raised: Since the account to be debited is zero, so all of its rods i 'assume the position shown in FIG. Consequently You can now adjust the angles 21 by turning the spindles 24 (Fig. 6) from the position shown in Fig. i indicated position? ii can be moved to position 211f without one of the rods i pull out of their position. The adder's reader also becomes as a result remain at zero and thus the ones actually specified in this department Show value.

The number 94 to be transmitted is now set in the adding machine. The number drums of the adding machine's counter then take this value corresponding position, d. H. the single drum rotates four units, and - the ten-drum by nine units from its zero position. Because these number drums are firmly connected to the gears 25 or to the slip rings 204, so must these parts also rotate into the appropriate position.

The spindles 24 (Fig. 6) are now rotated in the opposite direction as before and thereby the angle 21 moved back from the position 21,1 into the position 21 '(Fig. I). During the outward movement, the connecting rod 207 of the changeover switches 188 and 2o6 (Fig. 3) was previously pressed to the left by the driver 2o9. In this position, i.e. in the one drawn in dotted lines in Fig. 3, the levers of changeover switches 188 and 2o6 are now located. The magnets 62 of the angles 21 belonging to the units and tens are consequently excited by the current and attract the angles 22. The magnet 62 of the hundreds angle 21, however, is not excited because the corresponding slip ring 204 is at zero, ie such that its breaker point 2o5 is just below the two contact springs 202 and 203 , so the circuit of the hundred magnet 62 is interrupted at this point. As a result, the hundreds angle 22, since it is not attracted, remains in its zero position on the left, and the hundreds rod i is not moved out of its zero position.

In contrast, the units and tens bars i. Because those places corresponding slip rings 204 when setting the adder to 94 by four or nine units have been rotated from their zero position, none is found here Interruption by the interruption points 2o5 instead. As a result, the current flows through it the units and hundreds magnets 62, and the corresponding angles 22 are at the return movement of the angle 21 from the position 2111 into the position eil.

But this also causes the rods. i the ones and hundreds shifted to the right on their zero position. The displacement of these rods in turn causes the associated contacts 15 and 16 to be repeatedly connected and disconnected by repeatedly raising and lowering the levers . As soon as this zero position is reached, the interrupter 2o5 causes the current flowing around the magnet 62 to open. At the same moment, the previously tightened angle 22 is released and, pulled by the spring 27, snaps back to the left into its starting position. The associated angle 21, however, continues its movement to the right without any further influence on the rod i associated with it.

In the case described here, the ones rod i is therefore four times Have to cause the power to be switched on, so also shifted four units to the right until it comes to a standstill because it has the corresponding number drum 25 the adding machine is then turned back to the zero position and the current that the One magnet 62 flows through, has interrupted. Likewise, the ten rod i is around must be shifted nine units to the right in order to put the "ten wheel 25" in its Turn to zero position and thereby the associated breaker point 2o5 to take effect bring to. The bars z of the account just discussed now take the positions shown in Fig. I position shown. They show the value in relation to their zero position 094 (viewed from top to bottom), so they are in the requested Location.

The driving hooks 2 are initially still in the position shown in Fig. I Horizontal position drawn in dash-dotted lines. But now the holder 23 continues the angle 21 continues its way to the right by a small amount more than to move the rods i from zero to nine is necessary. This addition to the way will exploited to press the support bar 53 to the left and thereby the slide 28 to fall. The driving hooks 2 also fall into the position shown in Fig. i strongly drawn skew, and the account just discussed is turned off.

The addition of the path of the angles ei to the right is also used, around the connection 207 (Fig. 3) of the switches 188 and 2o6 by the driver 2o8 to push to the right and switch the current to the forward magnet 199 and to achieve the simultaneous deactivation of the magnets 62. The machine is thus ready to work after every booking.

Any other account (department) of the machine can now be handled without any change taking place in what has just been treated; because since the driver hooks 2 are in an inclined position, the projections can 3 can no longer be encompassed by angles 21 or - 2. Suppose that just covered Account, the parts of which now assume the position shown in Fig. I, should after some Time can be increased by the value 28. It is then done again by pressing down the associated button 40 and the lifting of the carrier 2 (Fig. i) the activation of the account to be treated. By turning the spindles 24 again the angles ei shifted together to the left (in the sense of Fig.i).

During this movement, the middle one, the tens angle 21, first encounters resistance in the form of the projection 3 of the tens bar i. As a result, this rod i must follow the path of its angle 21; there is repeated raising and lowering of the locking lever 8 or io and accordingly repeated closing and opening of the circuit which excites the ten switching magnet i99. During this process, the projection 3 of the one rod is detected and forced these rod for co-movement and operation of its corresponding switching magnet 1 99 during further movement (in Fig i is the lowest.). When the angles 21 have finally reached the position 20, the topmost one, the hundreds rod, will still assume the same position as before, since only now the angles 21 have reached their projection 3, the rods at the units and tens. on the other hand, depending on their previous distance from the \ Tull position uni, four or nine units (ie distances from the middle to the middle of the recess 6f have been shifted to the left The number drums of the adding machine now also show 4 and - 9 accordingly, so in the reading of the adding machine the number will be 094. The value previously displayed in the department has thus been transferred to the adding unit.

Now add by pressing the corresponding keys' or Actuation of other setting organs of the adding machine the value 28 to your already in the totalizer of the adding machine. As a result, the number drums take the Counter the position corresponding to the number I, 22. This number should now be used again can be transferred to the account that is still switched on.

Since the parts of this account are all zero, so find the same process takes place as before, when the account is still at zero 94 was charged: the angles 22 initially follow the angles 2i, the three locking levers18 are raised, the three corresponding reverse switching magnets Zoo are energized and the three digits of the counter are each switched back by one unit. Since the Hundred number drum has already reached its zero position as a result, so will the circuit belonging to it is interrupted and its angle 22 is released. Both In both other places there is another switching, then also with them the circuits opened by the breaker points 2o5, and 'the angle 21 can continue on their way while the account (the department) receives the requested Maintains position, corresponding to the value 122.
