DISPENSER FOR TREATING CHEMICAL
First Claim
1. In a domestic fabric drying machine adapted to treat fabrics by tumbling the fabrics therein with a quantity of water, treating chemical and transfer agent, the machine including:
- an enclosure rotatable about a nonvertical axis to impart a tumbling action to the fabrics;
air heating and circulating means adapted to heat and circulate a stream of air through the enclosure so as to carry moisture away from the fabrics during rotation of the enclosure;
means adapted to selectively energize and deenergize the air heating and circulating means so as to selectively permit the rotation of the enclosure without the flow of heated air therethrough during a treating operation;
an outer protective cabinet having an opening therethrough into the enclosure; and
a door pivotally mounted on the cabinet to close the opening;
the improvement of a dispensing means adapted to slowly introduce the water and treating chemical into the enclosure, comprising;
a reservoir tank carried by the door and adapted to receive and contain the treating chemical;
a valve carried by the door and adapted to control the discharge from said tank into the enclosure;
said valve including a valve operator;
actuating means incorporated in the cabinet to actuate said valve operator only when the door is in the closed position adjacent the cabinet; and
said valve operator being positioned so as to be brought into operable relation with said actuating means when the door is closed.

Abstract
In an automatic fabric drying machine including an enclosure rotatable about a nonvertical axis to impart a tumbling action to the fabrics, air heating and circulating means adapted to heat and circulate a stream of air through the enclosure, means adapted to selectively energize and deenergize the air heating and circulating means, an outer protective cabinet having an opening therethrough into the enclosure, and a door pivotally mounted on the cabinet to close the opening; a dispenser is provided for slowly introducing water and treating chemical into the enclosure. The dispenser comprises a valve controlled reservoir tank carried by the door and including a valve operator. An actuating means incorporated in the cabinet is adapted to actuate the valve operator only when the door is in a closed position adjacent the cabinet. In one embodiment the actuating means comprises a portion of the cabinet adapted to contact the valve operator and cause actuation thereof when the door is closed. In another embodiment the actuating means comprises an actuator adapted to contact the valve operator in response to a condition indicating initiation of the fabric treating operation.
