Abstract
The compressed spring acting on one end of the lever urges the lever in the direction to apply force to a pressure plate guided by the fixed bushings to apply pressure to the brake pads and discs to prevent rotation of a motor shaft received in the coupling. When the solenoid coil is energized, the armature lifts the end of the lever to relieve the pressure and release the brake. If the plunger at the other end of the lever is depressed, the lever will tilt to release the brake and the brake will remain released as long as the plunger is depressed. The same spring which biases the plunger upwardly biases the plunger in a rotational sense so the plunger can be rotated against the bias of the spring and cause the projecting pin to work against the cam on the end of the lever to tilt the lever in the direction allowing the brake to release. If the pin passes over the hump on the cam, the brake will remain released until the plunger is manually returned to its original position or until the coil is energized long enough to lift the other end of the lever and permit the projecting pin to pass over the cam hump and return to its original position.
