Abstract
A gear and boss protector for the spring driving mechanism of a tap selector such as a voltage regulator. A pair of hook cams form the protective means and they are mounted rotatably on the crank driven by the spring driving gear. One of the hook cams engages the driving boss on the driving gear should the gear reverse rotation in one direction, while the other hook cam engages the driving boss on the driving gear should the gear reverse rotation in the opposite direction. The engagement of the driving boss by the hook cam prevents the crank from being suddenly released causing damage to the gear or boss.
