The enclosed drawing shows a counter which is used to determine the lifting and the number of revolutions of parts in machines of every kind and for this purpose it is used can be easily connected to the machines in question.

Like other known counters, the counter is in a housing with a cover lockable, and the lid of the same is covered with viewing openings covered by a glass plate through which the number of revolutions indicated by the counter can be read from the outside can.

Fig. Ι shows the counter from above, section through the housing according to AB (Fig. 2),

Fig. 2 section according to CD in Fig. 1,

3 shows a part of the housing cover with inspection openings for reading off the number of revolutions,

Fig. 4 shows the section through the housing and counter according to EF (Fig. 2) and

5 shows the counter in section according to GH

(Fig. I). '

The same essentially consists of the number disks b mounted next to each other rotatably on axis α, each of which has a crown gear c with equally spaced wedge-shaped lugs as teeth on one side surface and an eccentric disk d with an eccentric ring c rotatable thereon on the other side surface. ¹ (Fig. 4), the latter for guidance on axis i contains a slot r and a pin k as a pinion for engaging a crown wheel c.

The axes α and i are fixedly mounted in the bearing block g and the latter is fastened in the housing.

On each number disc b there are raised numbers h from zero to nine evenly distributed over the circumference.

The end of a spring f attached to the bearing block g presses against the circumference of each number disk h.

Each of the springs f is, as FIGS. 4 and 5 show, provided at its free end by bending with an eyelet-like elevation and a straight surface adjoining it and arranged in such a way that it has the eyelet-like elevation in the positions of the respective number disc b is placed between two consecutive numbers h and with the flat end on one of the numbers h , whereby the number disc b is secured in its positions against rotation.

So that the flat end of the spring f has a secure support on the numbers h , it is covered with an elastic material.

The nose m located on the eccentric ring d ⁱ serves to lift the spring f resting on its circumference shortly before the rotation of the number disk b by the movement of the eccentric ring d ^l.

The pin k, which is also located on the eccentric ring ^{d 1 and} acts as a pinion in the spaces between the lugs "of the anstofsenden crown wheel c , has the purpose of rotating the number disc b connected to this crown wheel c through the movement of the eccentric ring d ¹ .

To connect the counter with the machine from which the revolution or Stroke numbers are to be determined, there is one on the housing stored, leading from the outside into the same

Claims (1)

Axis s, which carries a drive t ¹ at the end standing in the housing and a coupling at the end standing outwards. The drive t ¹ on axis s is in engagement with the wheel t, which is firmly connected to the first number disk b , so that by means of the wheels t, t ^l from the machine coupled to the axis s, the rotation is initially directed to the number disk b is transmitted. By the resilient sleeve u , the number discs b are held on axis a standing on each other. As is known, the first number disk b contains only the number zero, which is at the beginning of each revolution of this number disk b on its circumference in front of the relevant viewing opening ο of the housing cover. The remaining number discs b \ b ² , b ^s . . . are connected to the first number disc b in such a way that, when the latter is in front of a viewing opening o with the number zero, each of the number discs b ¹ , b ~, ^ ³ ... is in front of each of its ten positions marked by zero to nine one of the inspection openings ο can be placed. Before using the counter, all number discs must be turned to zero. The mode of operation of the counter is as follows: When the revolutions of the machine to be counted are transferred to the first number disc b , the eccentric disc d connected to ^{the eccentric disc d moves the eccentric ring d 1 in} such a way that the lug m on the eccentric ring d ^l moves the spring on the circumference of the number disc b f lifts off and thereby enables the number disc b to rotate freely. Furthermore, the pin k located on the eccentric ring d ^l rotates the same by one number division in the opposite direction by engaging the crown wheel c of the number disc b ¹ , so that instead of the number zero, the number one through the relevant viewing opening is displayed on the number disc b ^{l set at the beginning} ο can be seen. In this way makes about five revolutions of the number disk b is the number disc b ¹ a half turn and indicates through the display opening ο the number five, b at zehn'Umdrehungen the number disc makes the number disc b ¹ one complete revolution while the number wheel b ² a tenth of a Revolution, the number disc b ^l showing a zero and the number disc b ² showing a one, and so on Patent address: Tens transmission to roller counters, characterized in that the number rollers are provided on the side facing the lower order rollers with a crown wheel (c) and on the other side with an eccentric disk (d) , the eccentric ring (ά ^Λ ) of which is provided with an extension by means of a Slot (r) engages over a fixed shaft (i) and is equipped with a pin (k) to divide the digit by one number at each full revolution of a digit roller by engaging the pin (k) in the crown gear (c) of the next higher digit roller keep turning.
