Abstract

PURPOSE: To make braking power readily variable and make stop time constant by providing a metal plate fixed to part of a lever between both poles of a magnet and letting the magnet perform adjustment of braking power by the use of an electromagnet or the like for the same.
CONSTITUTION: A metal plate 2 is fixed to one end side of a vertically turnable lever 1 whose other end side is fitted with a pan. This metal plate is positioned between both poles of an electromagnet 3 and is so provided as to cross the magnetic flux thereof. This electromagnet 3 is connected to a voltage regulator 4 of variable voltages so as to make the intensity of said magnet variable. In this way, the braking force for the vibrations of the lever 1 may be changed, by which the vibrations may be rapidly stopped even if they are large, thus the stop time may be made constant irrespective of the magnitudes of vibrations.
