Description

The proposal for a telephone searcher ir consists in the constructive form of its implementation.

In FIG. 1 is a side view of the finder, and FIG. 2 - view from above (in plan).

The solenoid ZHL- (Fig. 1) under the action of current pulses rotates the gear /. Gear 2 is braking, just like spring 5, so that the searcher doesn’t slip Vi off from its position. Both gears are mounted on a hexagonal axis 4. Three drums 5 of insulating mass (Fig. 1) are mounted on the axis, with protrusions along a helical line, the rarabanchiki are fortified with studs in couplings mounted in the searcher frame 7 (Fig. 2). On the frame of the seeker, contact group 10 is also strengthened, the contact of which is closed when the seeker leaves the rest position, with the disk / 2 sitting on the same axis 4.

Under each drum there are brushes a, b, with its spring feathers. The feathers have bulges. The protrusions of the drum, sliding along the feathers, alternately press these feathers to the downstream common multiple field of all seekers.

Three groups A, B, C of a multiple floor are mounted in one plane (strings or plates) and reinforced with strips 8 on panel slats 9.

A full turn of the drum corresponds to 12 steps: the first position is quiescent, the second is 10 “exits, the 11th position is for signaling.

The subject matter of the invention. /

A telephone finder, characterized by its use, for pressing the flexible feathers of the brushes a, b, c to the flat contact field, mounted on the axis 4 rotary drums 5c with protrusions, is arranged along a helical line.
