Abstract
A device suitable for use by children which recycles broken crayons and other materials by melting and molding. A stationary melting pot securely retains the charge material during heating. A housing substantially surrounds the melting pot and an associated mold chamber to isolate young operators from all heated surfaces. The melting pot is charged from outside of the housing by use of a filling port. A remotely operated gate controls the flow from the melting pot to a mold. A door provides access to the mold when open and prevents access to the mold chamber when closed. A warning light glows when a heating element for the melting chamber is energized. Various safety switches interrupt power to the heating element if certain conditions are not met.
Claims21
A device for molding crayons or toys, comprising:
- a housing defining a restricted access area having interior sidewalls;
- a door movable between open and closed positions that provides access to the restricted access area;
- a stationary melting chamber within the restricted access area;
- an electrically powered heating element adjacent the melting chamber;
- a mold chamber in the restricted access area and connected to the melting chamber, the mold chamber defined in part by the door and interior sidewalls of the housing;
- and
- a mold having two parts within the mold chamber, where the two parts are held together in part by the door when it is in the closed position.
A device for recycling wax pieces, which comprises:
- a housing defining a restricted access area;
- a melting chamber in the restricted access area for producing liquid wax from wax pieces;
- a flow path within the restricted access area and extending from the melting chamber for directing the flow of liquid wax;
- a gate that controls the flow of liquid wax from the melting chamber to the flow path;
- a mold connected to the flow path;
- a door that provides access to the mold when the door is in an open position and prevents access to the mold when the door is in a closed position;
- and
- an interlock between the gate and the door, which prevents the door from moving from the closed position when the gate is permitting flow.
A toy molding device for use with wax material, which comprises:
- a stationary melting chamber;
- an electrical heating element for heating the melting chamber;
- a mold;
- a housing substantially surrounding the melting chamber and the mold so as to restrict access by a user to the melting chamber and the mold, the housing including a door having an open position which provides access to the mold and a closed position which prevents access to the mold;
- a gate having a open position which permits flow of the material between the melting chamber and the mold, and a closed position which prevents the flow of the material between the melting chamber and the mold;
- and
- an interlock that prevents the door from moving to the open position when the gate is in the open position.
