Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
An apparatus for removing slag from a torch cutting operation comprising: a torch for cutting a sheet of metal into a predetermined shape; a water tank suitable for filling with water; a plurality of support members for supporting the sheet of metal above said tank; a porous conveyor located in said tank, said conveyor having openings of sufficient size to allow slag to fall therethrough but sufficiently small to prevent the article cut from the sheet of metal from falling therethrough, said conveyor operable for transporting the article to a finishing area and for transporting slag to a collection area located in said tank, and means for propelling said conveyor.
