CONSTANT MESHING FORCE RACK AND PINION FOR WEIGHER

摘要

In a condition responsive device, such as a load-responsive weighing scale, a rotatably mounted pinion is engaged with a pivotably mounted balanced rack which is movable in response to change in the condition. A spring is provided for urging the rack into engagement with the pinion and for maintaining the meshing force between the rack and the pinion substantially constant during all positions of the rack.
