Description

The present invention relates to a step finder device for circular motion of a forward stroke, in which additional rows of contacts connected to bypass contacts of the remaining rows are applied in a multiple field. For the horizontal movement of the vertical rows of the specified floor, two independent rotating parts (rotors) are used.

In FIG. 1 and 2 are shown in two projections and in a partial section of the proposed searcher; Fig, 3 - his principal electrical circuit.

The multiple field of the seeker consists of a series of groups arranged parallel to each other in the vertical plane of the co-tact plates / (Figs. 1, 2 and 3). In the case shown in the drawing, eleven plates are provided in each group. All rows of such vertical groups are located in an incomplete circle and are divided in turn into three segments A, B, and C (Fig. 1 and 3). In the case shown in the drawing, in each such segment, ten vertical rows of contact plates are combined, directed toward the center of the circle with their contact surfaces. In front of the horizontal rows of contact plastia of each segment, bypass contact plates 2 are located, electrically connected to the respective plates of the latter (340)

It has a horizontal row of contact plates of all three segments. Thus, the lower plates (in our case, the plates // row) form a special additional row of contacts of the multiple floor.

For the selection of the horizontal movement of the vertical field rows, two independent rotating parts (rotors) are used.

The first rotor (with forty pairs of brushes) is mounted perpendicular to the base in the center of the circle created by the multiple-floor segments. In our case, ten horizontal rows of brushes are fastened on it, in each row four brushes 3 are located at right angles to each other. Each horizontal row of brushes is fixed on the rotor axis so that the brushes of all ten rows are installed one over the other. Each row of brushes is located against the corresponding row of co-tact plates. Brushes are isolated from the rotor and from each other.

The sleeve of the second rotor with four pairs of brushes rotates independently of the axis of the first rotor. An additional eleventh row of brushes is mounted on the sleeve fitted on the axis of the first rotor.

The searcher is equipped with electromagnets (Fig. 3) with mechanisms for rotating the first and second rotors, which drive

The rotational axis of the rotors with brushes mounted on them, the direction of movement of the brushes of the second rotor opposite to the direction of movement of the brushes of the first rotor.

There is also a rotor position indicator, designed to determine on which contact plates the rotor brushes stopped (not specified in the drawing).

The searcher is equipped with two pulse groups for rotor electromagnets, which consist of sets of contact springs that are fixed on the base of the searcher so that the electromagnets of the first and second rotors are closed and opened by the course of the electromagnets (not shown).

The work of the proposed seeker is as follows. If the searcher is used as a linear connector or a group selector, then when the first digit is dialed, the electromagnet of the second rotor is activated and sets its brushes on the selected contact plates of one of the three groups and the additional eleventh row. When the second digit is dialed, the electromagnet of the second rotor is activated and sets the vertical rows of brushes on the selected contact plates of the specified groups. Release and return of the seeker rotors to zero is performed using the above-mentioned pulse groups and head contact. When returning the rotors, they take as many as ten steps. The zero position of the searcher is considered to be the position at which the vertical row

brushes, did not reach the first contact plate in the decimal group, occupied the bypass plate.

If the searcher acts as a call finder, then the first rotor is started up through the pulse group. When the brushes of the first rotor are mounted on the contacts of the caller, the pulsation circuit is cut off. After the installation of the first rotor, through its pulse group, the second rotor is started, and its installation is carried out similarly to the installation of the first rotor. The presence of a pulse group on the searcher provides a sufficient guarantee against falling into synchronism in the event of the launch of several call finders, which is achieved by adjusting the pulse group to the different speeds of the rotors of these searchers.

If the proposed searcher needs to be applied as a quadrant, it is enough to change the contact field in it, reducing each horizontal row by one group, double the number of rows and eliminate it according to the appropriately modified scheme.

The subject matter of the invention.

The step finder of a circular motion of a forward stroke, characterized by the use in an additional field of an additional row of contacts connected to the bypass contacts of the remaining rows, for selecting the horizontal movement of the vertical rows of which floor two rotating parts (rotors) independent of each other serve.
