SU20269A1 - A device for the psychotechnical selection of wagon drivers and chauffeurs - Google Patents

Description

Main patent for. No. 10772 describes a device for the psychotechnical selection of wagonmen and drivers, in that there are two pairs of wheels parallel to each other in front of the tramway platform with all the control levers. The latter are interconnected by two endless ropes with two pairs of sticks attached to them, driven by the rotation of the front pair of wheels from the electric motor. Above the rear wheels there is another place, in the middle horizontal part of which there are slots for endless ropes. The side portions of the platform are slightly raised to the middle and are provided with openings to hold the mists located behind them. When the experimenter manually removes the plates that hold back the balls, the latter roll down toward the moving checkers on the ropes, the movement of which controls, like a car, the subject, and its task is to avoid touching the checkers with the pieces.

In order to eliminate the inconvenience associated with manual adjustment of the movements of the mashes, in the proposed device the removal of the masking plates is made by incorporating the latter into an electrical circuit, for closing which, when passing through the drafts, are used contacts located on the platform near the front wheels. and connected to an electric meter.

In the schematic drawing of FIG. 1 shows the layout of the contacts; FIG. 2 is a view from above.

The device for automatic rolling of the mill is as follows. The plates P for the masses are held over their slots cut in inclined areas by electromagnets K on the basis of the numerators. These electromagnets are associated with an electric meter L having an arrow and a dial with 100 divisions. The counter is placed laterally under one of the sloped pads. The electric meter L, in turn, is connected to the two T-Y contacts, located
