CONTROLLED CHEMICAL INJECTION SYSTEM FOR WASHING MACHINES ABSTRACT OF THE DISCLOSURE A controlled chemical injecting system is disclosed for adding chemicals to two or more simultaneously operating washing machines. The apparatus includes a reset electrical timer with associated control circuits for each chemical to be added to the washing machine. The reset timer is set for a predetermined time interval during which the chemicals are to be added to the washing machines. In connection with the reset timer, the control circuit for each washing machine has receiving means for receiving a signal from the programmer of each washing machine, signal holding means activated by the signal from each washing machine, a first signal blocking means which prevents the signal from the holding means from activating the reset timer if the reset timer is activated by another washing machine, a second signal blocking means which blocks the signal from other washing machines from reaching the reset timer when it has been activated by a first washing machine, directing means for directing the load output from the automatic reset timer to the chemical injecting means associated with the washing machine whose signal has activated the automatic reset timer. The circuit also contains a time delay means to permit the automatic reset timer to be reset before accepting a signal from a washing machine calling for the same chemical.
