Timer with reversible motor

A timer means comprising reversible repulsion inductive, shaded pole non-directional synchronous clock motor with a drive shaft and connected with an alternating current power supply, an elongate operating arm with an inner end secured to the drive shaft and projecting radially therefrom, a normally closed clock motor control switch controlling the flow of current between the motor and the power supply and arranged in fixed radial spaced relationship from the shaft and engaged and opened by the arm when said arm is in a normal rotative position to de-energize the motor, stop means spaced circumferentially from the control switch to stop turning of the arm by the motor in a direction away from the control switch when the arm reaches a predetermined rotated position and to cause the motor to reverse and rotate in the opposite direction amd move the arm back to said normal position, a service switch in a power line controlling operation of a means controlled by the timer means and positioned relative to the control switch, stop means and arm to be engaged and operated by the arm when said arm is in a predetermined position within its travel between said control switch and stop means and starter means including a normally open switch connected with and between said alternating current power supply and said motor to selectively energize the motor and initiate turning of the arm away from said normal position and out of engagement with the control switch.
