Description

A very important disadvantage of currently used Odner-type counting machines is that the main part of the machine — the installation drum with sliding teeth — is not a sufficiently stable and reliable mechanism.

In the proposed machine, the sliding arms are replaced by solid gear sectors made from one piece of metal. Sectors are worn directly onto the drum shaft and do not require copper discs. Thus, according to the inventor, the design of the drum is greatly simplified: the number of parts and the weight of the drum are reduced, together q increases the reliability of the machine and the operation of the machine, since the integral toothed sectors have enormous advantages over the sliding gears.

In FIG. 1-3 pictures of drums installed in different positions; FIG. 4-mechanism for moving the drum; Longitudinal section; FIG. 5 is the same side view.

In the proposed machine, the shaft / setting drum 2 is held in bearings having the shape of an ellipse, with the line of the major axis coinciding with the line of gears resulting (540)

GO counter, so that the drum with the axis can move, i.e., occupy the upper or lower position closest to the gears of the resulting counter. At the lower position of the drum, when it rotates, the toothed sectors will engage with the gears of the resulting counter; but when the drum is moved to the upper position, the engagement is stopped, i.e., this part of the circumference of the drum is idling. The movement of the drum, or rather, the strokes of its movement, is provided so that the drum on one part of a circle equal in length to nine teeth of the sector approaches the tooth of the resulting counter, and the rest of the circle passes in the upper (remote) position. The length of the drum engagement path is marked with a thick line and an arrow on the drawing.

In FIG. 1 shows a gear sector set to zero position; FIG. 2 is the next sector, set at 2, and FIG. 3 sector, set on figure 9.

The installation or introduction of operating numbers is carried out in the same way as in existing machines, i.e., by moving the levers down the notch and setting against the digit placed on the machine casing.

 The drum, i.e., the coupling and the disengagement are performed automatically, with the help of a mechanism consisting of a shaft / carrying a drum 2 with integral gear sectors, mounted in bearings having an ellipse shape, and provided with a clip 4 supported on roller 5, and a cam 6 with a roller 7, walking along a shaped groove of a motionlessly fixed disk 8, for the purpose of engaging and disengaging the teeth of the sector with the gears 70 of the resulting counter.

The washers 4, part of the circumference of which are cut, hold the drum 2 in the upper position, resting on the rollers 5 with an uncut part of the circumference; but if you rotate the drum so that a cut-off part of the circumference falls against the roller 5, the drums, due to their own weight and under the action of the cam 6, will approach the teeth of the resulting counter (will engage).

The subject matter of the invention.

A counting machine, characterized in that its shaft (carrying the drums 2 with integral gear sectors) is mounted in bearings having the shape of an ellipse, and is equipped with a washer 4 supported on roller 5 and a cu; Track 6 with a roller 7-, walking along the shaped groove of a fixedly mounted disk 8, with the purpose of coupling and uncoupling the teeth of the sector with the gears 1Q of the resulting counter.
