Abstract

Abstract Apparatus for supporting metal plates and sheets during torchcutting operations and for receiving, storing and carrying away the waste scrap and slag materials. A stationary, elongated work table provides support during cutting and is open for scrap and slag to fall through. An elongated trough beneath the work table receives and stores waste materials. Periodically, the operator actuates a drive mechanism which converts the storage trough to a shaker conveyor for carrying the material away to a discharge point.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 193 words
In a burn-cutting apparatus, the combination comprising a stationary elongated work table including two longitudinally extending, laterally-spaced beams defining the table side margins, and a series of transverse beams spanning the longitudinally extending beams for supporting metal plates at selected stations along the table length, the spaces between the transverse beams defining openings between which cut-off scrap and waste material slag can fall, an upwardly open shaker conveyor trough extending directly below the work table for reciprocation longitudinally of the table to convey the fallen material from the area beneath the table, said trough being coextensive in length with the table for handling all of the fallen material, drive means for imparting a reciprocal conveying motion to the shaker trough to move the material in a longitudinal direction, and control means for selectively energizing said drive means, said table having dependent guides extending along both side margins of the table for directing the fallen material into the trough, said conveyor trough being appreciably narrower than the table and said marginal guides taking the form of downwardly convergent plates overlapping tHe marginal edges of the trough to guide the fallen material into the trough.
