Abstract
A belt tensioner has a pair of pivotally mounted cam members which engage a stationary mounting strap. One cam is pivotally mounted on a block which is drivingly connected through a pivotal lever to a linear motor. The one cam is operative to engage a stationary strap when the motor is operated to urge the belt sheave bracket to pivot in a direction to increase the tension in the belt. When the one cam and block are moved by the return stroke of the motor, the other cam, which is mounted on the belt sheave bracket, engages the stationary strap to prevent movement of the belt sheave bracket relative to the strap.
