US Patent:
40477061, Sep 13, 1977
Filed:
Oct 18, 1976
Appl. No.:
5/733288
Inventors:
Harlan C. Tronvold - Minneapolis MN
Assignee:
Paper, Calmenson & Co. - St. Paul MN
International Classification:
B23K 3704
US Classification:
266 49
Abstract:
An apparatus for removing slag during torch cutting of a metal work plate by an oxyacetylene torch which is remotely programmed to cut a predetermined pattern in a metal plate. The molten metal slag particles fall through an upper and lower section of a conveyor belt and onto the floor of a tank filled with water. The lower section of a continuous moving conveyor belt transports the slag along the floor of the tank to a disposal area. The workpiece which is cut from the metal plate drops into the tank but is prevented from falling to the floor of the tank by the top section of the conveyor belt. The top section of the conveyor belt transports the workpiece to a finishing area. Movable and adjustable members are provided for supporting the work plate during the cutting operation.
Harlan C Tronvold from Savage, MN, age ~91 Get Report
