DISPOSITIVO ANTIURTO PER STRUMENTI DI MISURA A QUADRANTE

摘要

A shock absorbing device for use in dial measuring instruments comprising a balance lever interposed between a pinion and a coaxial toothed wheel of the multiplier mechanism disposed between the movable indicator member and the movable feeler of the instrument, said balance lever being pivoted on the common axis of said pinion and toothed wheel and intercepting during its pivotal movement in one and the same direction a first radial driving finger integral with an arm connected to the pinion and a second radial driving finger integral with said toothed wheel, a resilient liaison being formed between the balance lever and the radial driving fingers by the opposed action of the ends of at least a spiral spring connected at its inner end to said balance lever.
