Abstract
The tooth depth of a gear meshing with a worm wheel, such as used in an electricity meter register, is adjusted by providing a mounting plate for holding the shaft of the toothed gear having a limited range of motion for adjusting the distance of the gear from the worm. The toothed gear has one end of its shaft attached to a mounting plate having a J-shaped cutout provided along one edge. The shaft of the gear is mounted to the 'hook' portion of the cutout. Movement of the J-shaped cutout in a direction within the plane of the mounting plate causes a corresponding change in the distance of the toothed gear from the worm, thus enabling the mesh depth between the gear and the worm to be easily adjusted. The arrangement has no moving parts and can be formed using a simple die-stamping process.
