摘要

Improvements introduced in the manufacture of automatic scales, characterized in that the stabilization system is formed by three pulleys, two of which, the lateral ones, have in their lower part recesses that allow the direct coupling to them of the counterweights of the balance, while the third pulley, located between the previous two, in contact with them and in a plane located slightly above the one they occupy, is capable of rotating around an axis that joins the frame or chassis of the balance, acting as a tensioning element of the system's only stabilizing belt, one of the ends of which, passing between the central pulley and the left of the two lateral pulleys, ends at the bottom of the latter, while the other end passes through the other side pulley and will end on the right side of it, joining both ends to said side pulleys by means of separate screws.
