ABSTRACT:
A weighing balance comprises an anti-shock device arranged in the mechanical linkage between an object receiving plate and a rack and pinion driving an indicating member, to protect the teeth of the rack and pinion when the receiving plate is abruptly loaded or unloaded. The anti-shock device consists of a transmission lever articulated on the rack and held by a spring to transmit translational movement of the receiving plate in normal use, said spring giving way to allow pivoting of the transmission lever in the case of an abnormal shock on the receiving plate.
