Abstract
A clutch for engaging and disengaging rotary systems and devices such as alternators and generators, which includes a hollow engaging knob fitted with projecting engaging pins, a spindle shaft and plate mounted on a rotating shaft and cooperating with the engaging knob and engaging pins, and a drive pulley rotatably positioned on the rotating shaft and having seats for selective registration with the engaging pins. A spring is positioned in the hollow cavity of the engaging knob to facilitate biasing of the engaging pins through apertures in the spindle plate and in registration with the seats in the drive pulley when the clutch is engaged. Retraction of the engaging knob and engaging pins against the bias of the spring facilitates retraction of the pins from the pulley seats, and effects disengagement of the clutch and free rotation of the drive pulley.
