Description

The invention relates to devices in counting machines for printing the sum or difference of numbers and one of the addends, with movable slats and digital disks to account for the sums of the sum of all addends.

In the proposed fixture / it automatically prints two numbers-deductible and the remainder, or one of the terms and the sum (which is required for deposit operations in general, in particular, for cashless payments, where it is very important to determine the new balance after any calculation) , to print the required numbers on a sheet of paper inserted under typical marks, a wedge is applied, moved by a flexible rod controlled by a handle, and used for pressing through vertically movable ridges on spring-loaded type marks .

In the device with the purpose of including digital disks, an eccentric located under the toothed sliders, controlled by the same handle, was used to take into account the Total sum of all the terms.

In FIG. 1 shows a longitudinal section of the device along line A-A (in FIG. 3); FIG. 2 is the same, along the line BB; FIG. 3-top view of it; FIG. 4 is a front view of it; FIG. 5- detail

clutch rack with gears; FIG. 6 and 7 view of the arrangement of the digital font in the pads and the pressure device (in 2 projections).

The device consists of a wedge J4, located above the J9 / I pads with digital fonts 20, 2J, moved by a flexible rod 23, which is wound on the drum 22 through a gear 25, 26, driven back by the handle 24, pivoting by hand 90. Kolodyi J9,19 in the front | 1 part, facing the inside || 1, have gear racks 18, 18 with which small teeth 5, in which the teeth 5 5 interlock with the fins of pads 19 bearing the fonts 20, and the gears 6 with the racks of pads 19 bearing, fonts 27, are in constant grip. The gears 5 and 6 are tightly connected to the large teeth 5 and 6, of which the gear 5 are in permanent engagement with the rack 7 (to set the number to be reduced), and the teeth 6 are attached to the rack 2 (for the set of the number to be subtracted) only during move them forward along arrow a.

During operation, the creamer / creamer 2 is without movement. When the cremallera 2 moves, the latter simultaneously engages, in addition to the counters 6,

with gear 1 | emalier / move it in the same direction. In the holes of the blocks / P and /. There are columns 30, 27 intended to press under the action of greens / 5, / J and wedge / 4 onto the spring-loaded type signs (fonts) 20, 21 below.

The effect of the counting device described above is as follows. Yri dialing: Umm of diminishing and subtracting 1 numbers, with simultaneous fixing of the total amount of all sets of turnover, the handle 24 is set vertically under 90 ° (Fig. 1); force the hand to move the corresponding number of sign to decrease the number of crestal /, as long as a figure is needed for each cremaler (they are marked on the serrated ax ah in addition to counting from top to bottom) does not / reaches the limit line 3 of the cremaler windows 4; set over, her number to be reduced. Kremalier / rotate the teeth 5, which are mounted loosely on the axis JO, tightly connected with small teeth 5, which, attached to the toothed racks 18 of the pads 19, move them to the appropriate number of positions.

Once the number of the number to be reduced is established, a subtracted number is set (in exactly the same way) on the rack 2; The kremaler 2 in the working position interlock with the gears 6, connected tightly to the small gears 6, which, in addition to coupling with the gear J ekey 18 pads 19, are engaged with the sliders 7.

The second ends of the sliders intermittently interlock under the action of an eccentric 27, rotated by gear 25, 26 by 270 ° (counterclockwise) when lifting the handle 24 upwards, with the gear 28 of the digital disks of the counter 9 (Fig. 1). ,

Since the rack 2, during operation, comes into engagement with the teeth 5, the tracker /, moving them to the BTO in the same direction and in the same number of positions (and the order of the bill in digital bbix fonts, blocks 19 goes in the direction opposite to the pads 19), then the amount on the creamers / will be reduced by the number of characters of the deductible. During this time, the sliders 7 rotate the teeth of the 28 digital disks of the counter 9, set in slots // the amount of the set of cremalis 2.

The pads 19, 19 put into work kremaler / and 2 will bring up columns 20, 21 with spring-loaded sample marks 20.21 under the crests 13 and 13. On the windows of the 1st row sets of numbers to be reduced and subtracted on cremals /, 2, the handle 24 goes down, the eccentric 27 is set to the position indicated in FIG. 2, the slide slider 7 out of engagement with the gears 2 digital disks of the counter 9. At the same time, the drum 22, which sits on the eccentric axis, winds up the swivel bar 23, displacing the wedge 14 fastened on it, which is pulled between the fixed roller 16 and the movable, angularly , up and down ridges 13, 13. Combs, under the action of the skull of the 11th part of the wedge 14, press down on columns 2f, 2Г of spring-loaded type marks 20, 21 and will print the result of typing (subtracted and difference) on the sheet inserted under the type marks paper. With the next po1; the removal of the handle 24, it is modeled. redemption of boron on kremalyerah, by returning them by prine ins 29 to another position. The wedge 14, too, is returned to its original position by a spring. The set of the counter is not redeemed and with each new set on the rack 2, the amount in the counter will increase accordingly, showing the total amount of turnover for any period. ,

By means of a special key, not shown in the drawing, it is possible to place the eccentric 27 so that the coupling of the sliders 7 with the gear 28 of the counter 9 will occur at the moment of quenching on the creamer; this same counter 9 will produce subtraction, showing the difference in the windows //.

In order to cancel the dialing, in the event of errors, release key buttons 17, designed, when pressed against them, turn off the pawls 16 from engaging with rack, by virtue of jero, the springs are set to the non-operating position.

The subject matter of the invention.
