Title: Water-filled burning table

Abstract: The entire table frame is a tank. The upper portion of the tank provides a working area and the lower portion forms a closed water flow control chamber. Removable gratings in the upper portion underlie support rails which support steel plates to be cut into desired shapes by an automatic profile burning head or a gang of such burning heads. The introduction of compressed air into the lower chamber displaces water into the upper section to submerge the removable grating. The water subdues the noise and smoke of the burning operation, cools the plates being burned, thus reducing distortion and catches the slag produced. Small pieces of metal falling off the plate being cut are cooled by the water and retained on the gratings. Release of air pressure from the lower chamber allows the water in the upper portion to return quickly to the lower chamber for convienent removal of the metal pieces from the gratings.
