Description

Booking and similar calculating machine The invention relates to booking and similar calculating machines and in particular a summing unit control mechanism, the complementary value resulting from a coating in a summing mechanism in the converts a true negative balance and prints it as a .such.

With two balancing units or addition-subtraction-summing units Equipped machines work when neither of the two summing units is overdrawn or where only a summing mechanism is overlaid, quite satisfactorily if that particular one Summing unit is equipped with a known complement conversion mechanism. In the case of a further summing unit, however, which has not yet been used to deliver a true negative balance was established made the occurrence of such an overlay so far the implementation of a series of complicated, manually initiated machine operations required to effect the necessary conversion. Have such machine aisles the further disadvantage that a further summing unit in the one just mentioned by Hand-initiated conversion process must be used, which thus for others Purposes is lost.

It is known to have machines with multiple summers and a complement conversion mechanism to create for all summing units. The invention aims, however, to provide means by which a machine with one for converting a coating in only one summing unit constructed complement conversion mechanism can be easily set up, around those resulting from coating in one or more additional summing units Convert complement values to the true negative sums. Of the The invention accordingly relates to a booking or similar calculating machine with a plurality of summers and a single engagement control mechanism for each totalizer, with a cam conversion mechanism and a connecting link, that normally occurs during complement conversion at machine gears in operative connection with the engagement control mechanism is set for a particular totalizer, and is characterized in that an overlay control key for a second addition-subtraction-summing unit and a mechanism is provided which is activated by the operation of the coating control key is controlled to the connecting member from the operative connection .mit the engagement control mechanism for the first mentioned summing mechanism and in operative connection with the engagement control mechanism for the other summing unit, so that the complement conversion mechanism calculates and prints a true coating in the second totalizing unit.

The invention is illustrated below in an exemplary embodiment of the drawings, namely Fig. i shows a diagram of the partially broken away Machine keypad, Figure 2 is a view of part of the mechanism of the left i machine side, Figure 3 is a sectional view of the coating thrust cam assembly which controls the machine during complement conversion machine gears, Figure 4 shows a mechanism normally used to unlock the locked overlay totals and subtotal keys is assigned to a summing unit, and part of the mechanism which controls can be, if another summing mechanism is covered, Fig. 5 a mechanism, which is usually effective to lock one of the sum pull buttons when that associated summing mechanism is covered, FIG. 6 one associated with the mechanism of FIG Intermediate locking mechanism, which locks out the sum pull button for a solar panel, when an overlay control key is pressed for another totalizer, and vice versa.

The mechanisms of the machine on which to understand the embodiment Reference is made to earlier patent 746 ogi and are only briefly explained here.

In summary, it can be said that the method used so far for the automatic conversion of a complementary value arising from a coating in -the true negative value according to patent 746 ogi, which allows the printing of reveals either a sum or subtotal of a true negative value, made four machine aisles required, namely: First gear: The sum of the emptied from a summing unit and transferred additively to an auxiliary storage unit. Second course: The supplementary number was emptied from the storage plant and from subtracted from the previously emptied totalizing unit. This left the true negative value in the latter back.

Third course: the real negative sum came from the storage plant emptied and printed. The above applies to a true negative sum.

If a true negative subtotal is wanted, one comes through pressing an overlay subtotal key set:% feohanisrnus in action and causes if the true negative value from the accumulator in the fourth machine gear is emptied, this is again transferred subtractively into the Suinmierwerk, whereby the latter is brought to the same state in which it was as the automatic Complement conversion machine gear has been initiated.

In the subject matter of the invention, this is an automatic complement conversion mechanism set up to also include one that occurs in another totalizing unit at the coating To convert complementary value.

The complement conversion mechanism is in one of those in the patent 746 ogi described similar way to one of the summing works, which afterwards as the No. i-summing unit is called, usually assigned to one in b`-say To convert the complementary value occurring in the summing unit into the true negative value.

It is known to provide a mechanism in earlier machines for automatic locking of the sums to, g keys for either totalizer No. i or another totalizing unit (hereinafter referred to as No. 3 totaling unit), if a coating occurs in the assigned totalizer.

Adapting the existing complement conversion mechanism to the No. 3 summing mechanism is roughly described.

If there is a coating in the No. i summing unit, it is a lift rod i (Fig. 2) set up, which forward as can be seen in this figure, can be moved, so that a sum pull key 17 for this summing mechanism against be actuated blocked and thereby the machine user is made aware that a Coating is present. At the same time, one normally unlocks the No. r totalizer associated mechanism the normally locked cover key 26 (Fig. i) and Intermediate cover key 27, the actuation of one of the two keys being automatic Series of four machine aisles initiates in a known manner. Dic when it occurs These four gears required machine gears are referred to in detail below called for pulling the coating from the summing unit # 3.

Pressing one of the buttons 26 or 27 causes a shaft 8, as shown in FIG. 2, it is pivoted in the counter-clockwise direction. At the shaft 8 is a hub is attached to which an arm 7 is arranged at 15 by means of hinges is, so that the arm is allowed limited lateral pivoting movement. The arm 7 is normally under tension one around pivot point i; coiled torsion spring (not shown) so that the arm is in preparation for a summation from the No. i summing unit usually in a right-hand position, such as from the front of the machine see is held.

On the left side of the arm 7 is one for making the selection of the no. 3-summing mechanism serving plate i4 attached. and a similar (not shown) Plate is on the other side of the arm for selecting the No. i totalizer intended.

Approximately in the middle part of the arm 7 protrudes an extension 16, which is designed at its end as a thrust curve, which together with a downward extension 6 of a selection lever 5; the latter is rotatably attached to a pin 29 attached to a machine side frame. The lever 5 is forked at its upper end, so that it forms an extension 4 and an empty right-angled projection 30 .

In a keypad support plate is suitably a key 2 slidably supported, which for controlling fully complement conversion machine gears, in relation to the no. 3-summing unit, serves and afterwards as ÜZ. 3 button will. At the t'Z. 3 button there is a pin 3 that when you press the former cooperates with the right-angled projection 3o of the lever 5 to the lever to pivot on its pivot pin 29 in the counterclockwise direction and zu.bewirken that the downward extension 6 of the same with the shear curve surface of the extension 16 cooperates so that the arm; to the right, as from the front of the machine can be seen from, is panned. This causes the plate 14 to have a buzzer latch 13 is aligned for the No. 3 Sunlmierwerk. The sum button pawl 13 for the No. 3-Sunimierwerk has in its center vain pin 12 to interact with the Plate i4. The lower end of the sum key pawl 13 has a pin 31, which cooperates with a thrust cam surface of a ratchet adjusting lever 103, so claß pawls 32 and 33 in operative connection finit a swinging lever 34 for the no. 3-totalizer can be adjusted in a known manner.

When the shaft 8 is pivoted as described above, the touches Plate 14 the pin 12 of the sum key latch 13 to pivot the latter and zti cause the pawls 32 and 33 to block the scliw-irigenderi I lehel 34 and thereby the No. Set 3 totalizer for a total tractor gear. @ \ 'during this machine gear becomes a storage unit (not shown) for receiving the Complementary coating selected by a thrust curve 36 (Fig. 3) in a known manner.

While rotating one shown in Fig. 3 and in the earlier one Patent specification 746 011 precisely described C1> Erzugschubktirvenl> Augruppe allows a thrust curve 35 of the shaft 8 (Fig. 2) to receive a further G counter-pointer movement, whereupon a finger 9 of the arm 7 a pin io of the usual subtraction control lever i i for the r. 3-totalizing unit touched. The subtraction control lever i r then operates adjusting pawls 32 and 33 so that the No. 3 totalizer during the second Machine gear for a Sul> traction machine gear is set. Simultaneously causes the thrust curve 36 (Fig. 3) that the storage unit, which the complementary overlay number is selected for a summation machine gear. During this operation therefore becomes the complementary number drawn from the Speicherw-crk by the number 3 totalizer subtracted, leaving the true negative value in said summing unit.

During the third pass, the No. 3 totalizer becomes sequential the fact that the upper end of the plate 14 is under the influence of the surface of the Thrust curve 35 (Fig. 3) remains in contact with the pin 12 of the sum key pawl 13, for a summation tractor gear set to the true negative sum of the same to pull. After this total has been drawn from the number 3 totalizer, the selects Thrust curve 36 again the storage unit for an addition process in a known manner the end. This will make the true balance from the # 3 totalizer during the third pass emptied and transferred additively to the storage unit.

The machine is now performing its fourth and final machine run. Just before that, at the end of the third pass, causes a large part of the thrust curve 35, that the shaft 8 is brought back to the starting position, thereby enabling the arm 7 is returned to its normal position by a spring (not shown) be determined for the No. 1 totalizer and the plate 14 opposite plate in engagement with a sum key latch for the No. i-summing unit finds.

During the fourth pass, the thrust cam 36 causes the Storage plant is selected for an accumulator pulling machine aisle.

. The printing mechanism, which during the first three; Operations, as disclosed in earlier patent 746,091, rendered ineffective. became, . is made effective again so that the amount of the true balance is printed, and the. Ribbon mechanism, which, as explained in more detail below, for Red printing is suitable, causes the coating to be printed red so that it can be used can differ from a positive number.

At the end of the sum, consisting of four work steps, it can be seen that that the summing, # yerk No. 3 as well as. the storage unit is also set to zero and the machine for further calculations in relation to the No. 3 totalizer is ready.

In Z, # vischerisiimmenzugmaschine gears (: here Z @ vischensurnmenschubkurve 38 (Fig. 3) on the coating thrust cam assembly is effective to, when the coating subtotal key 27 is actuated, the shaft g to pivot at the appropriate time and thereby cause the arm g in its counterclockwise position remains, so that the product discharged from the storage plant true balance during the fourth working passage transmitted subtractively to the No.3-totalizer and thereby this totalizer is left in its original position, that is, the complementary number is in this, so that other items can be added to or subtracted from this complementary coating.

Certain intermediate locking devices are provided to ensure proper operation of the parts during a complement conversion machine operation with respect to the No. 3 totalizer; these devices will now be described.

Blocking and releasing the ÜZ. 3 button To change the ÜZ. 3 button 2 (Fig. 5) for a reasonable time during a complement conversion engine run in Anyone can keep the relationship to the No. 3 totalizer in the depressed position Appropriate locking and unlocking mechanism under the control of the color The ribbon adjusting mechanism is operated, provided for this button will; said mechanism came in the second operation of a complement conversion machine operation be adjusted from black to red printing position, # n which he is held is printed until the correct aldo in the first half of the fourth pass will. During the second half of this fourth operation, the ribbon adjustment mechanism returned to normal black print position.

Release of the normally locked coating and intermediate coating buttons when pressing the Ü.Z. 3 key In the machine according to the invention, the existing Mechanism by which the occurrence of a coating in the No. 1 summing unit reduces the Overlay and intermediate overlay buttons 26 and 27 (Fig. F) unlocked, used, and only brief reference is made to the mechanism disclosed in previous patent applications taken.

When the No. 1 totalizer is overdrawn, a plating shaft 65 becomes (Fig. 4) pivoted counter-clockwise. This movement of the shaft 65 is via a Link 66 and a lifting rod 67 transferred to a pawl 68, the the latter is pivoted counterclockwise to a projection 69 on the foot thereof in a notch 7o of the shaft of a sum pull button 71 for the No. 1 totalizer to swivel and thereby lock the said button against being pressed.

The counter-pointer movement of the shaft 65 is also a pawl for the coating and intermediate coating keys 26 and 27 (Fig. t) and thereby the latter even for being pushed to initiate a complement conversion engine gear free.

On pins 72 and 73 attached to the machine frame (Fig. 4) a slide 74 is arranged, which has a downwardly directed extension 75 has, which is set up for the interaction finitely the lever 5 (Fig. 2 and 4). Between a pin 76 of the slider 74 and one attached to the keypad frame Pin 77 is attached to a spring 78, which serves to keep the slide 74 normally to hold in the position shown in Fig.4.

A projection 79 on the upper part of the slide 74 is used to cooperate with a projection 8o of the lifting rod 67.

If the ÜZ. 3 button 2 (Fig. 1, 2, 5 and 6) after the occurrence of one Cover is pressed in the number 3 totalizer, the lever, as mentioned above, pivoted counter-clockwise. During this pivoting movement, the extension touches 4 the extension 75 of the slide 74 and moves the latter according to FIG. 4 to the left, whereupon the projection 79 touches the projection 8o of the lifting rod 67 and thereby to the left and the coating shaft 65 is moved counterclockwise.

The counter-pointer movement of the coating shaft 65 causes a known Manner that the overlay and intermediate overlay buttons 26, 27 (Fig. 1) are to be depressed be released.

Pressing one of the buttons 26 or 27 causes the machine, @as explained above, a complement conversion machine gear related to the No. 3 summing unit carries out.

If the ÜZ. 3 button 2 (Fig. 1, 2, 5 and 6) to bring back up Unpressed position, as explained above, is released, the lever 5 (Fig. 4) brought back clockwise, whereby the extension 4 moved away from the extension 75 of the slide 74 and the spring 78 is made possible the Bring slide 74 back to the right, whereupon the parts are again according to FIG. 4 are set.

Should a coating in the No. 1 totalizer occur simultaneously with a Coating occur in the No. 3 summing mechanism, then the coating shaft 65 (Fig. 4) already at the time when the ÜZ. 3 button 2 (Fig. 2) is pressed in their Are located in the opposite direction. In this case the slide would move to the left 74 (Fig. 4) due to the pressing of the ÜZ.3 button be an empty movement, in which the protrusion 79 would move to the left until it reached the already displaced The lead would have reached 8o.

On the other hand, if the No. 1 totalizer contains a positive balance at the time of the occurrence of a coating in the No. 3 totalizer, the shaft 65 will become when the TS is pressed. 3 button, as explained above, swiveled counter-clockwise. It is evident that this pivoting of the cover shaft 65 causes the pawl 68 to lock the No. 1 sum pull key 71 against being depressed; however, there is no consequence since the user is not concerned with the No. i summing unit at this time. When the complement conversion engine operation is complete, the coating shaft 65 is returned clockwise in a known manner and as disclosed in Patent 7, +6 091, causing the No. i sum pull key 71 to be unlocked again.

It is clear from the foregoing that although a complement conversion machine gear in the no. 3-totaling unit the rev. Normally assigned to No. i-totaling unit andlungsuiechauismus used, this in no way the state, positive or negative, in which the No. t totaling unit is at this time still affects When the complemenite conversion engine operation is completed, this will affect the normal operation of the plating control mechanism associated with the No. i totalizer. Intermediate locking mechanism between the sum pull button for the No. 3 totalizer and the ÜZ. 3 button Between the (TZ. 3 button 2 (Fig. T, 2. 5 and 6) and the sumptuous button 17 for the No. 3 totalizer an intermediate locking mechanism is provided so that, when one key is locked, the other is free, and vice versa; this mechanism will now be described.

If there is an overlay in the # 3 totalizer, the totalization key will be 17 (Fig. 1, 2 and 5) are blocked in a known manner against being pressed, and if so this happens, a shaft 82 (Fig. 5) is pivoted counterclockwise.

Fixed to the cell 82 is an arm 83 which has a pin 8: 4 carries, on which a connecting member 85 is pivoted rotatably. On a pen 86 of the link 85 is rotatably one slidably located on a pin 88 Lifting rod 87 arranged. A connecting member is rotatable with a pin 89 of the lifting rod 87 9o connected, which is coupled to a pawl 9i by a pin-and-slot connection the one at its upper end with a notch 93 in the shaft of the No. 3 sum key r7 has a lockable projection 92.

When the cover shaft 82 is pivoted in the counterclockwise direction, is the pawl 9i pivoted clockwise. whereupon the protrusion 92 into the notch 93 enters to push the sum pull button 17 for the number 3 summing unit against to lock.

The pawl 9i is an intermediate locking device for the VZ. 3 button 2, and this will now be described.

On a pin mounted in a place value plate (not shown) 94 (Fig. 5 and 6) a locking lever g_3 (Fig.6) is attached. also for supporting the pawl 9i is used. On a pin 96 of an extension 97 of the locking lever 95 is a spring 98 is attached, the other end of which is attached to a pin of the Stellemvertplatte is attached. The spring 98 normally holds the locking lever 95 in the position shown in FIG. 6 position shown, in which a projection 99 of said lever under the Pin 58 (Fig. 6) of the ÜZ. 3 button 2 is located.

The locking lever 95 (FIG. 6) has a surrounding the upper end of the pawl 9i forked top.

When the cover shaft 82, as mentioned above. pivots counter-clockwise (Fig. 5), the pawl is pivoted clockwise according to FIG. 5 and counter-clockwise according to FIG. This counterclockwise pivoting of the pawl 9i also pivots the locking lever 95 in the counterclockwise direction so that it moves the projection 99 out of the path of the pin 58 of the ÜZ. 3 button 2 removed so that the latter is free to be pressed at this time.

When the coating shaft 82 (FIG. 5) completes a coating total tractor gear is pivoted clockwise in the usual way, the pawls 9i and the locking lever 95 is returned clockwise as shown in FIG. 6, the spring 98 supports this return movement. This causes the projection 92 of the pawl gi (FIGS. 5 and 6) is removed from the notch 93 in the shaft of the sum key 17 and the projection 99 (Fig. 6) of the locking lever 95 again under the pin 58 in the Shank of the ÜZ. 3 button 2 sets. As a result, the sum key 17 is now free, to be pressed, and the ÜZ. 3 button 2 is prevented from being pressed by the projection 99 locked.

From the foregoing it can be seen that when the sum pull key 17 is free to be pressed, the ÜZ. 3 button 2 locked against being pressed is, and vice versa.

-You will find that with subtotal tractor gears the Coating shaft 82 on the left is in a counter-pointer position as the amount of coating at the end of the machine aisle again in the familiar @@ "eise to No. 3-Suinmierwerk is transferred, and therefore the sum pull key 17 is blocked and the ÜZ. 3 button 2 free to be pressed at this time.
