Abstract
358,049. Impulse and momentum speed indicators. SOC. SUISSE D'HORLOGERIE FABRIQUE DE MONTILIER, Montilier, Switzerland.-(Assignees of Helfer, A. G. ; 8, Rue de la TerrassiÞre, Geneva, Switzerland.) July 2, 1930, No. 20073. Convention date, July 4, 1929. [Class 106 (iii).] A pointer m controlled by spring u is secured to the worm wheel i and receives impulses to rotate it through an angle proportional to the speed to be measured through the worm elements g, h fixed to the connecting-rod d having a slot e engaging with the pin f secured to the speedometer casing and having a collar c surrounding an eccentric b secured to the shaft a rotating at a speed proportional to that to be measured. The spindle of the pointer m is in two parts j, l, the part j being fixed to the wheel i and having secured to it the disc n carrying the rod k extending into the part l secured to the pointer and also carrying the pin p engaging in a recess q of the disc o with sufficient play to prevent the pointer m being affected by small variations in speed. The disc o carries a pin r which can engage with a pin s to prevent the pointer from returning beyond its initial position. The several elements are held together by the parts t, v and the plate w. Instead of worms and worm wheel i toothed racks and a spur wheel may be employed.
