Abstract:

A photographic developer turning system for periodically turning a film processing container. An electric motor connected to an output shaft is mechanically coupled to a clamp disposed about a cylindrically shaped film processing container. The motor turns the container about an axis perpendicular to the axis of the container. A cam, mounted on the shaft, opens a microswitch to interrupt the supply of power to the motor, after one rotation. A variable time delay switch connected to the microswitch permits the motor to be energized after a preselected time. After each rotation, the microswitch resets the time delay switch to zero so that the container may again be rotated after a preselected time delay.
