Description

This invention relates to a counting device with movable digital strips. According to the invention, above the mounting slots provided at the upper and lower ends with conventional arc transfer parts, in the box lid there is a rotatable covering board or valve with cutouts corresponding to the installation slots, but without transfer parts; depending on the position of this valve, at any given moment, only one arc transferable part of the installation slots located under the valve is released, and either at the upper end of the slot, with the valve folded down - which corresponds to the addition, or at the lower end of the slot with the valve folded up - which corresponds to the subtraction. At the same time, along the installation slits of the lid are rows of numbers 9,8,7,6,5,7,8,9, instead of the usual rows O-9. If now, along the valve cuts on both sides of it, apply the O-4 digits so that O on both sides is closed, & 4 - at the open end of each slot, the valve itself should be positioned in such a way and give it a shape such that

tilting its numbers 6-9 on the lid closed, according to the case, above or below figure 5, the rows of numbers on the lid of the box and on the valve are supplemented in such a way that an upward or downward digital row of about-9 is obtained. To move from addition to subtraction and vice versa, it is enough with the index finger of the hand holding the female to throw the narrow valve so that the device can be controlled only with one hand.

The proposed fixture allows for a series of additions and subtractions in any order, with each digital movable plate when added is brought to its final position by moving it to failure upwards, and during subtraction by moving it to failure downward.

In the existing devices of this kind, in which each digital mobile bar is equipped with digital number 9 continuation and can be moved upward beyond the "O", which appears in the result window, with both kinds of calculations, the digital bar does not have any signs, which would allow to distinguish the top position of the strap from the bottom. With

using such conventional devices: neither: it is not immediately visible whether the digital bar has reached its upper or lower end position. In the proposed device, signs that automatically differ from each other appear in the result windows, which allow to distinguish the lower (corresponding to addition) or upper (corresponding to subtraction) positions of the digital strips. To this end, the digital bars on the upper or only the lower half are marked with rows of numbers O-9 lisch in ascending order and, moreover, only in such a way that the extreme number of the row falls on the upper or lower edge of the bar and for the digit 9 or O, the plank has neither a special sign nor continuation, and beyond O-9, a wider space can be moved up and down. Since the digital strips for digital 9 do not have a continuation, the emptiness in the result hole, appearing on the movement of the plank (during production) down to refusal, proves that the bar must be raised again (set to 0 with the transition to the next decade is through the upper arc transferable part of the slot). On the contrary, when subtracting, after the final lifting of the digital bar, the white background of the bar appears in the result window, without a digit, which is a distinctive (from the corresponding addition) sign that the bar must be moved down again (set to P with further the change of the top ten through the lower conversion part of the cut).

The proposed device thus automatically, without putting special characters on the digital strips and without increasing the size of the device, by supplying the strips with extensions, is distinguishable for adding and subtracting characters; This happens because each digital bar must be moved to its full length and returned to its main position. All kinds of calculations can be made on the front side of the proposed device. In the proposed device, it is necessary to use a digital device for the navting device.

which is located inside the installation field in order not to hinder the movement of the digital strips to the end positions, but to inform them of the correct direction in these positions. Such a guiding device can be achieved as follows: when making teeth on the digital slats, the material corresponding to the cavities is not removed, but remains in conjunction with the slats, but bends downwards, forming on the underside of the slats protrusions of the bottom or a special false board. These protrusions on the bottom or on the inlay board can have spring properties, so that they also press the planks against the lid board.

To secure using a simple means of the said rotary valve, which is rockingly attached to the box lid, in the proper position, when carrying or packing the mashina, it is possible to use a counting schtif, used when using the device, to provide lateral spring brackets that fit onto the edge of the device and together with so on the rotary valve.

FIG. 1-9 illustrate an exemplary embodiment of the present invention:

FIG. Figure 1 shows the front view of the fixture, with a portion of the flap closing valve shown in isolation, so that the arrangement of numbers on the lid is visible (on the right side of Fig. 1 the lid is shown in the position for addition and on the left in the subtraction position); FIG. 2 is a vertical section along line II-II in FIG. one; FIG. 3 is a horizontal section along line III - III in FIG. 1 and 2; FIG. 4 - front view, with the cover shown in isolation, and some mobile slats removed; FIG. 5 is a perspective view of a part of the plank; FIG. 6 is a perspective view of a supplementary board serving as a guide; FIG. 7 and 8 are front views of a portion of the device, in which one of the movable slats is depicted in its extreme positions indicating that the bar is extended beyond the positions corresponding to

numbers 9 and 0; FIG. 9 is a modification of the guide insert board.

The device has a flat, compact shape and is made from sheet metal so that it can be carried in a pocket. The bottom 10 of sheet metal is provided with forward-curved edges 11, 12, IS and 14. The lateral edges 16 vi 17 and the upper edge / 8 of the lid 75 are folded backward. These edges at the ends are bent further inward, as indicated by 19, so that they grip the bottom 10. Both boards are fastened together with the help of curved edges 20 attached to the lower end of the lid. Both boards limit the chamber 21 in which the moving parts of the device are placed.

Several parallel cuts 22 were stamped into the cover. FIG. 1, the first from the middle, the left-slit is shown fully. The upper end 22 and the lower end 22 of this slot have small, left-facing, hooked appendages 23, 24, the branches of which are parallel to the main part of the slot 22. These slots serve, as described below, for changing tens; if necessary, it is also possible not to make the connection between the long slit and its short appendage 23 or 24. Above each of the slits 22, the lid has a viewing hole 25 through which the movable strips 26 located in the chamber 21 are visible.

These slide bars are shown in FIG. 4 and 5. Each of them consists of a metal strip provided with a series of flaps 27 bent down. By folding these valves at the edges 28 and 29 of the plank, a series of teeth 28 are formed, separated by depressions 27. At the same time, the valves form a guide bar 30 In the device shown in the drawing, there are teeth on each side of the strip 22, wherein, as shown in FIG. 4, the bar at the bottom ends at the troughs and at the top with the teeth. The twelve upper teeth on the left side are painted; they are very different from the lower teeth. FIG. 4, this color is indicated by hatching. Between the cavities on the upper half of each plank are the numbers 9, S, 76,

5, 4, 3, 2, 1, Oh, and the number 9 is at the end of the bar.

Between the bottom 10 of the fixture and the strips 26 there is an inserted guide plate 31 of sheet metal. This bar is provided as shown in FIG. 2, 4 and b, with several spring lugs 32, two such lugs intended for each movable bar. The width of these tabs corresponds to the distance between the flaps 27 of the movable strips bent downwards, so that the latter can only move along the projections in the longitudinal direction, not being able to move along them in the transverse direction. At the same time, the protrusions push the plates to the cover, forcing them to rest against it.

Instead of the insert board shown in FIG. 6, the board of FIG. 9 devices. Here, instead of the protrusions 32, protrusions 32 are arranged and the boards 3 / stamped from the material serve as guides for the laths 26.

On the lid / 5, approximately in the middle of the device, there are protrusions 33, 34 directed upwards. These protrusions serve as nipples for the reversing valve 35. The axis of this bearing is located on the axis of the grater deposited on the lid. The valve is provided with a number of parallel slits 36, the distance between which is equal to the distance between slits 22 in the cap 15 and which coincide with these last slits. The slits 36 are open to the hinge side. On each side of the valve, next to its notches, the numbers 4, 3, 2,}, O, are plotted, as shown in FIG. 1. In addition, the valve is provided with inspection holes 37 that coincide with the same holes 25 in the lid when the valve is folded upward, as shown on the left side of FIG. one.

As shown in FIG. 1, with the valve folded down (to the right of FIG. 1) on the straight sections of the slits formed by the slits 22 and 35, the rows of numbers 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 are obtained. Lower arcuate appendage 22, 24 of the slot 22 is closed by a valve.

in this position, the device permits the production of addition and multiplication, as indicated by the plus sign on the left side of the valve and the multiplication sign on its right side.

If the valve is folded upwards (to the left of Fig. 4), then along the straight sections of the cuts there are rows of numbers 0.1, 2, 3, 4, 5, 6, 7, 8, 9, the upper arc-shaped appendage 22, 23 of this the slot is closed by a flap. In this position, the device can perform subtraction and division, as shown by the minus sign on the left side of the valve and the dividing sign on its right side. For the production of the fold, the valve is folded downwards and all the strips 26 are first brought to O, i.e. in such a position that O is against viewing holes 25. This is done by pulling up the speaker, from the fixture of the end 38 of the wire bracket 39, upwards, the lower end of which, as shown in FIG. 2 is located under the movable bars 26. Moving the bracket 39 upwards is limited to the stops 40. Further use of the bars 26 is carried out in the usual way. Unpainted teeth show that the bar should be moved downwards, and colored teeth indicate that the bar should be moved up and that the counting pin 41 should be inserted into the side appendage 22 and transferred to the lower edge of the short notch 23 in order to move the left side of it one unit bar.

If, for example, one of the slats is visible in the viewing hole, and a slat to the right of it is moved out of the counting operation, it moves upwards and the pin is inserted into the arc-shaped slot 25 and then the slider on one place downwards and, therefore, „9 disappears from the viewing hole. Since the bar ends immediately after "9", the bar itself disappears from the viewing hole. A guide bar appears in the hole (Fig. 7). Then the scoring pin should be inserted into the gap between the teeth of the standing left notch, which is next to the "O", and then move it together with the plank upwards, and then move the pin into the arc-groove. This completes the counting operation.

If, during subtraction, in the viewing hole you can see „About any strip, and the strip located to the right of it must be moved downwards with a transition to the next ten, then„ f is removed from the viewing hole and instead of it in viewing holes 37, 25 (Fig. 8) there is a clean part of the plank. This shows that the pin should be inserted into the cavity of the above bar, located next to "O", and then move the pin downwards and transfer it to the arcuate appendage 22 24.

If the plank is moved not downwards, but upwards, then the „About the plank passes behind the viewing hole and a part of the plank becomes visible. This shows that the bar had to be moved downwards. The error can be corrected by immediate additional movement of the bar downwards.

The device is attached predominantly to such length that it cannot be moved beyond the described signal or end positions. In these final positions, the bars rest against the walls of the box. The extreme left slat 26 may, if necessary, be provided with numbers different from those of the other slats. For example, its numbers may have a different shape, may be composed of a number of points, or have a different color.

Such a device can be pushed into a pocket-shaped case open from above. In order for the counting pin to be always at the device, it is supplied with two plugs, 1 42, mounted on the edge of the device. At the same time, these clamps fit valve 38 to the lid of the device.
