摘要

Electromechanical and automatic regulating device of one or more speeds, particularly for turntables, recorders and the like, characterized in that it comprises an armature that supports a rotating shaft that can be coupled with means generally known to the motor from which the speed is to be regulated, on said axis At least one regulating member consisting of a parallelepiped-shaped body of insulating material is mounted in the center of which is rotatably mounted the mounting member and on the opposite lower bases parallel to the rotating shaft, the ends of two folded rectangular sheets are held. essentially at right angles and superimposed by a stretch to each other, so that they establish among themselves (when the regulating organ is at rest) a good electrical contact; of the two partially overlapping sheets which come to be substantially parallel to the larger side of the body in the form of a parallelepiped, the also parallel to the rotary axis, the outer one being of eminently flexible metallic material, one of the sheets being at least electrically connected to a Isolated ring collector, coaxial of the rotating shaft, ring on which a contact brush supported by a suitable insulator is supported by the armature, the other blade being electrically connected to the mounting means, and therefore to the mass of the device .
