Description

The invention relates to a device for controlling the printing unit of statistical machines, which, with the help of locking slides, either prevents or allows the print hammers to work, and consists in the fact that the setting of each of the locking slides in the locking position is done by several Working slide monitored by the machine can be carried out in different operations the machine become effective, and that manually adjustable retaining slide make the individual working slide of your choice ineffective. By a such an arrangement can achieve an adaptability of the control as shown in FIG the table contained in the description of the present invention is expressed.

In a known embodiment, a machine-controlled device is disclosed in which a rod prevents printing. This mechanism works continuously during a whole Operation when the first card of a new group is still in the scanner box of the device and there is no manually controlled device to turn off the non-printing mechanism.

Furthermore, a machine is known which contains hammer stops, which in turn are designed in this way that they lock the hammers. This machine has no device through which the hand-released hammers can be locked when pulling the buzz.

Furthermore, a device is known that locks the type carrier when there is no card in the The card magazine or the card pocket. Means by which the type carrier is locked by hand when a card is in the pocket are not provided for in this device.

In contrast, the device according to the invention shows an arrangement in which the pressure for each ίο controlling element a plurality of control devices is provided which are operated by the machine, and a corresponding plurality of hand control devices, with the help of which each of the machine control elements at will can be made effective or ineffective, thus creating the aforementioned great adaptability the control is achievable.

In the drawing, an exemplary embodiment of the concept of the invention is shown for explanation by means of a tabulation machine controlled by the recording cards.

Fig. Ι shows the computing part of the machine with the Device according to the invention;

Fig. 2 shows the device according to the invention in side view, seen from the right of Fig. 3; Fig. 3 shows the device from the front; Fig. 4 is a fragmentary view from the left of Fig. 3; Fig. 5 is a section along VV of Fig. 3, and Fig. 6 is a section along VI-VI of Fig. 3. In the arrangement of the tabulation head shown in the drawing, each print hammer A is generally retained by a hook B , which engages in a projection C of the hammer. At a certain time in the machine's work cycle, the hooks i? retracted for all hammers A by a known device, whereupon a spring D acting on the end E of each hammer rotates the latter about their pins F so that they strike against the type G and thereby produce a pressure on the paper which around the Paper roller H is set. The control device according to the invention is attached to the frame / tabulation head. It contains a horizontal locking slide 1 for each hammer A , which works together with the nose C of the hammer in order to intercept the hammer, if necessary after the disengagement of the hook B.

A spring 2, which is attached to the locking slide 1, seeks this from the nose. C to pull away to the hammer released position (ie to the left in Fig. 2 and to the right in Fig. 1). The slide 1 is shown both in FIG. 1 and in FIG. 2 in the releasing position.

With each locking slide 1, four vertically guided working slides 3, 4, 5, 6 cooperate, each of which has an inclined surface 7, 8, 9, 10 which cooperates with one of the four pins 11, 12, 13, 14 that are laterally attached the locking slide 1. When one of the working slide (z. B. 3) is pressed down, its inclined surface 7 acts on the associated pin 11 of the locking slide 1 and presses the latter against the action of its spring 2 from the releasing position into the locking position in which it the nose C. of the associated hammer and holds the hammer back. Each working slide is pressed down by a spring 15, 16, 17, 18, which is stronger than the spring 2 of the locking slide 1, so that each working slide would slide down on itself and bring the locking slide into the locking position.

However, each working slide has a manually operated holding slide 19, 20, 21, 22, which has an inclined surface 23 which cooperates with a pin 24 of the associated work slide. When a retaining slide, e.g. B. 19, is in the position shown in Fig. 2, the associated working slide, e.g. B. 3, held against the action of the spring 15 in its upper position, so that the locking slide 1 remains in the releasing position.

If the holding slide, for. B. 19, but pulled to the left in Fig. 2, the associated working slide 3 is pressed down by the spring 15, provided that this movement is permitted by a device to be described. The inclined surface 7 then acts on the pin 11 and pushes the locking slide into the locking position.

A second holding member 31, 32, 33, 34, which is controlled by the machine, is arranged below each working slide. Since it is generally necessary to control a number of side-by-side print hammers in the same manner, each machine-controlled element is in the form of a rod which, for all hammers, extends transversely under the associated working slides. These machine-controlled holding members 31, 32, 33, 34 are to be referred to below as holding rods, specifically as the first, second, third and fourth holding rods for the sake of simplicity and clarity. The mode of operation of these holding rods, however, will only be described in connection with the four working slides 3, 4, 5, 6 assigned to a single locking slide 1 and a single hammer A.

The second, third and fourth support rods 32, 33, 34 generally take a position directly under the working slide 4, S and 6, which prevent a working slide even if he is released from his manually operated retaining slide 20, can fall because he is through the corresponding machine-controlled support rod 32 is held in the upper position. Consequently the locking slide 1 remains despite the release of its working slide by its retaining slide in the releasing position, and its movement into the locking position depends on whether the holding rod 32 is lowered or remains at the top, as will be described further below.

The first support rod 31 is generally located not immediately below the working slide 3, so that the latter when released becomes, falls and comes into engagement with the support rod 31 under the action of the spring; here-

at its inclined surface 7 moves the locking slide ι into the locked position. The first handrail can be raised in a manner to be described in order to prevent the working slide 3 falls down.

The tabulation head can be adjusted so that it is in any desired column or column Prints a plurality of columns on each card sensing machine pass; this can be done by that one is assigned to the first working slide 3 in each of the columns concerned Retaining slide 19 left in the position of FIG. 2 and the three other retaining slides 20, 21, 22 after on the left in Fig. 2 pulls out.

With this setting the slide 19, 20, 21, 22 is prevented by the holding slide 19 that the working slide 3 falls down, and the working slide 4, 5 and 6 are held by the support rods 32, 33, 34, which during the operations remain with card sensing in the position shown in Fig. 2, held above.

In order to hold the holding slide 19, 20, 21, 22 in the set position, a safety slide 35 is provided, the pins 35 ″ of which cooperate with notches 35 ^and the holding slide in order to hold them in each of their two positions.

To control the printing of the sums, i. H. to determine whether only subgroup totals alone, totals alone or both are to be printed or not, funds are provided around the first support rod 31 both during operations for printing To raise group totals as well as grand totals and to allow the second handrail 32 goes down during the operation for printing a group total, and by the third To let the support rod 33 go down during the operation for printing a grand total.

The following facility is provided for this purpose:

On a shaft 36, which is referred to below as the total pressure control shaft, is a double-armed lever attached (see. Fig. 4), one arm, 37, engages under a pin 37 "which attached to an end plate 38 of the second and third support rods 32, 33 supporting slide frame is, while the other arm, 39, engages under a pin 40 which is attached to an end plate 41 of the first support rod 31 attached to supporting sliding frame is.

The two end plates 38 of the sliding frame, which carries the rods 32, 33, are guided by pins 42 which are attached to the fixed frame 43 of the device and pass through slots 42 ° in the plates 38. The support rods 32 and 33 rest freely in the slots 32 ″ and 33 ^{a of} the end plates 38 and extend transversely to the direction of these plates.

The end plates 41 of the sliding frame connected to the first support rod 31 are similarly guided by pins 44 which are attached to the fixed frame 43 and pass through slots 44 ″ in the panels 41. The first support rod 31 rests freely in slots 31 ^{s of} the panels 41.

When the summing pressure control shaft 36 moves counterclockwise from its normal position (Fig. 4) is rotated a certain distance, one arm, 39, moves up and raises the frame 41 carrying the first support rod 31, while the other arm, 37, descends and the frame 38 carrying the second and third support rods 32, 33 also drops down.

A spring 45, which is attached to the arm 39 of the double lever 37, 39, seeks the sum pressure control shaft to rotate in this direction, however, a corresponding movement of the shaft is in the generally prevented by a holding arm 46 connected to the shaft (see. Fig. 6), the carries a pin 47 which rests on a projection 48; Part 48 is freely rotatable on another Shaft 49 and extends beyond this shaft to at the other end an arm 50 (Fig. 2) by which the projection 48 can be pulled aside if it is desired that the sum pressure control shaft rotates.

The working arm 50 of this holding member 48 (see. Fig. 2) is with the front sum shaft 51 of the Tabulation head connected by an intermediate piece 52 and an arm 53 which is attached to the shaft 51 is. Front sum shaft 51 is the same as shaft 72 of the British patent 461 612 and rotates a certain amount with each operation of the total drawing in the clockwise sense, so that with each operation of the summing the projection 48 of the holding arm 46 is withdrawn and the total pressure control shaft 36 is to a certain extent Piece rotates (in the direction of the clockwise in Fig. 2, opposite to the direction of the clockwise in Fig. 4). _

In this way, the first support rod 31 is raised in each operation of the sum printing, while both the second and third rods 32 and 33 seek to fall. There it is desirable that only one of these two poles fall, namely the second at a subgroup total and the third at a grand total, a voting device is provided which the retains one or the other of these two rods 32 and 33 in their raised position, nevertheless the frame 38 carrying them is lowered with each operation of the summing.

For this purpose, there is a slide 54 (see FIGS. 1 and 2) for the second and third holding rods 32 and 33, the projection 55 of which is generally below the third support rod 33 and prevents it from falling when the frame 38 is lowered. This slide 54 is pulled by a spring 56 to the right in Fig. 2 and carries a pin 57 which is against a lever 58 lays; this lever is operated by a shaft 59, which is only at a grand total rotates a certain distance, so that the slide 54 in the operations of the group sum print remains in its normal position, and

therefore only the second holding rod 32 falls down, but the third holding rod 33 is held at the top by the projection 55 of the slide 54. During the operation of a total print, the shaft 59 rotates a certain distance counterclockwise in FIG Holding rod 32 is, which is thereby held in its upper position while the third holding rod 33 goes down. Merely for structural reasons, the arm 58 is loosely placed on the shaft 59 and connected by a spring 58 ° to an arm 58 ^& that is attached to the shaft.

In order to rotate the shaft 59 a certain distance at the desired moment, a spring 159 (see FIG. 3) is connected at one end to a pin 160 which is attached to the hub of the arm 58 ^& at the other end on the other hand with a pin 161 which is attached to the hub 167 "of a lever 167, the purpose of which will be described below.

Connected to the shaft 59 is a pawl plate 162, the pin 163 of which is connected to a pawl 164 cooperates, which is hinged at 165 on the machine frame. This pawl 164 holds the shaft 59 generally against the action of the spring 159 in the position shown in FIG. A link 166 (see FIG. 2) is articulated with the pawl 164, the other end of which is connected to it a machine part is articulated, which always performs a swinging movement when a total card is sensed, d. H. a special card that has a hole at a certain point which causes the machine to draw a grand total.

When a grand total card is sensed, limb 166 is dragged to the right in FIG and pulls pawl 164 back, causing spring 159 to counterclockwise shaft 59 rotates (Fig. 2).

On the front sum shaft 51 is a return arm 167 for the shaft 59 attached. This arm generally rests against a pin 168 of the pawl plate 162. With each operation of the total pulling, the shaft 51 rotates in the Clockwise, thereby moving arm 167 away from pin 168 so that the pawl plate 162 is not prevented from rotating counterclockwise when the pawl 164 is withdrawn in the operation of the totals drawing. When the shaft 51 is opposite rotates back clockwise, the arm 167 contacts the pin 168 and guides the plate 162 and return the shaft 59 to their normal position in which they are held by the pawl 164. To return the sum pressure control shaft 36 to its normal position, a return arm is provided 60 provided, which of the Rüokführwelle 61 of the sector is moved (see. Fig. I).

This shaft 61 can be of the tabulating main shaft driven by the device comprising shaft 45 of British Patent 461,612 drives.

The shaft 61 carries a portion 62 which, when the shaft rotates clockwise, through a Intermediate member 65 moves the return rod 63 for the sectors 64 so that the sectors are released will. A hook 67 engages at the end of an intermediate link via a pin 66 of the part 62 68, which engages with a slot 69 over a pin 70 of the return arm 60. The normal position of the Parts is shown in Figures 1 and 2; when the shaft 61 rotates clockwise, it moves Intermediate member 68 first to the right in FIG. 1 until the left end of the slot 69 against the pin 70 strikes, whereby the intermediate member 68 pivots the arm 60 upon further movement to the right (FIG. 1).

The surface 6o ^{x of} the arm 60 lies generally against a pin 71 of the arm 72 which is attached to the total pressure control shaft 36; the arm 60 is held in this position by a spring Öo ¹ ″ which connects the arm 60 to the intermediate member 68.

The arm 60, as described above, rotates clockwise with each operation of the machine pivoted; when its face 60 * moves away from pin 71, shaft 36 is free to move clockwise (in Fig. 1) to rotate (or counterclockwise in Fig. 2) if you do is made possible by withdrawing the pawl piece 48.

When the shaft 61 rotates counterclockwise (Fig. 1) back, the intermediate member 68 pulls to the left, and the spring 6O ¹ * moves the return arm 60 also counterclockwise (Fig. 1), whereby the shaft 36 is returned to its normal position as a result of the engagement of the surface 6o ^{x of} the arm 60 with the pin 71 when the shaft 36 has had the opportunity to rotate counterclockwise (FIG. 1).

It must be remembered that the lever arm 37 of the shaft 36 lifts the frame 38 when the shaft 36 is returned in the clockwise direction (FIGS. 1 and 3), and that the movement the shaft 36 is inhibited when the lower ends of the slots 42 ° in said frame come into engagement with the pins 41. With the shaft 36 so held, the return arm 60 will not move any further, but the link 68 will move further to the left in Fig. i, until the shaft 61 ends its return movement counterclockwise (Fig. 1) Has. This further movement of the intermediate member 68 is effected by the slot 69 allows, the spring öo ^ stretched will.

When the shaft 36 is returned by the return arm 60, it is held again, and by moving the pawl projection 48 until it engages the pin 47 of the above-described Ratchet arm 46; this movement of the pawl projection 48 is caused by the return

movement of the front sum shaft 51 caused.

A control card that is provided with a hole at a very specific point is Initiated or not to print.

For this purpose, a double-armed lever (Fig. 4) is attached to the shaft 49, which is referred to below as the card-controlled pressure wave, one arm 73 of which engages under the pin 74 of a frame 41 which carries the first support rod 31, during the the other arm 75 engages under a pin 76 of a further frame JJ which carries the fourth support rod 34 which is generally in its upper position. The card controlled pressure shaft 49 carries a pawl arm 78 (Figs. 3 and 5) which engages generally with a pawl projection 79 which is retractable by a member 80 which is actuated when the control hole in the card is sensed; the link 80 is ^{articulated to an arm 8o a of} the shaft 36 (FIG. S). When the pawl projection 79 is withdrawn, the card-controlled pressure shaft 49 rotates under the action of a spring 81 which is attached to the arm 73, so that one arm, 73, of the double-armed lever raises the first support rod 31, while the other arm, 75, the fourth support rod 34 can fall down. The card-controlled pressure shaft 49 is returned by a return arm 60 ° (FIG. 3) which, similar to the arm 60, is mounted on the shaft 51 so that it can rotate freely. The arm 6o ^a is actuated by a hook-shaped member 68 ^a (FIG. 3), which is similar to the member 68. It is actuated by an intermediate member which is similar to the part 63 described, and returns the shaft 49 to its original position by acting on a pin 82 of the arm 83 fastened to the shaft 49.

From what has been said it can be seen that the second, third and fourth support rods 32, 33 and 34 are disregarded from the control effected by the manually operated retaining slides 19, 20, 21 and 22, are generally in their upper position, while the first support rod 31 is generally stands below; the first holding slide 19 is pulled out to the left in FIG. 2, as a result the first working slide 3 by its spring 15 down into engagement with its selector rod 31 brought and moves the locking slide 1 of the associated hammer in the locked position. This setting of the slide prevents that the tabulating head prints in the columns with each card sensing operation, in that this setting has been made, except when a control card is sensed. In this If so, the first holding rod 31 is raised and the fourth holding rod 34 is lowered. Lifting the first holding rod 31 causes a lifting of the first working slide 3, and there the other three Working slide 4, 5 and 6 held up by their support rods 20, 21 and 22 is the locking slide ι now released the action of his spring 2, which therefore the locking slide 1 of the Hammer removed and allowed to do the printing on that operation.

If the fourth retaining slide 34 is also pulled out to the left in FIG. 2, the tabulating head prevented from printing every card sensing operation, including the operation for a control card since the fourth working slide 34 descends when the first working slide 31 is raised, and the locking slide 1 holding back from the hammer.

Are all four retaining slides 19, 20, 21, 22 one If the column is in the "On" position (to the right in Fig. 2), the machine prints in this column not at all, since none of the working slides 3, 4, 5, 6 can go down, even if the associated ones Support rods 31, 32, 33, 34 would allow this. Note the following: Is the second and third holding slide 20 and 21 in the position of FIG. 2 (in the "on" position), so a pressure take place neither with a group total nor with a grand total, because the second and third working slide cannot descend, even if the second holding rod 32 at a group total and the third support rod 33 descends at a final total.

With a device according to the invention, a control of the printing process can be independent in of each column in one of the following sixteen ways. If a hand-operated retaining slide 19, 20, 21 or 22 are in the "On" position is (i.e. in the position shown in Fig. 2), the associated working slide 3, 4, 5 or 6 prevented from falling, even if the associated machine-controlled holding rod 31, 32, 33 or 34 goes down, while if a hand-operated retaining slide is in position "Off" is (that is, moved to the left of Fig. 2), the associated working slide is free, so that it can sink down when the associated machine-controlled support rod is down.

With the help of the devices described it is possible to obtain a pressure of any particular To prevent the data of a card being stamped in a column or in a series of columns, while the data contained in other columns of the same card is printed.

With the help of the device described, the hole provided with an S expensive card is operated, any desired column of any card can be printed be effected by providing these cards with a control hole and the manually operated retaining slides 19, 20, 21 and 22 for the various Columns can be adjusted so that calibrated the desired control in accordance with the the table above.

The invention can also be carried out in such a way that it is opposite to that described and illustrated Arrangement .works.

Thus, the locking slide 1 can be pressed into the locking position by its spring 2, and that Lowering of one of the working slides 3, 4, 5 or 6 can move the slide 1 from the locked position into the free position.

The rest of the arrangement is the same as described and shown, but due to the reverse effect, the setting is the manually operated Haltesdhieber 19, 20, 21, 22 also vice versa with regard to their setting according to the table. In the first place in the The setting listed in the table, for example, the sliders 20, 21, 22 must be in the "Off" position be and the slide 19 in the "On" position, in order to achieve that the machine with every card except for the control rooms, but not for group totals or grand totals.

In the case of the reverse construction, in which the locking slide 1 is in the locking position by a spring is printed, the slider 20, 21, 22 should be in the "On" position and the slider 19 in "Off" position so that the machine carries out the work mentioned above.

Similarly, the slides 19, 20, 21, 22, their position is indicated in the table with "On", in the case of the reverse construction it must be in the "Off" position; those sliders that should be in the »Aue« position according to the table must be

the construction must be in the "On" position in order to achieve a certain mode of operation of the machine.
