<p>Automatic cutting machines carry flame cutting torches in close proximity of a workpiece and can force the torch into contact with an upturned cutaway piece from the workpiece, causing considerable damage to the cutting apparatus. The subject apparatus provides a break away torch holder (32) having a housing (38) surrounding a torch tube (36) which is mounted in an adapter (54). The adaptor (54) has a pilot (76) that matches a pilot seat (66) in the housing (38). The pilot (76) is held in the pilot seat (66) by resilient means (62) that allows the torch tube (36) to move with respect to the housing (38) when the torch (22) strikes an upturned cutaway piece. A switch means (84) is provided to shut the cutting machine (10) down when the torch tube (36) means is in the housing (38). Sealing means (88) is also provided to protect the piloting apparatus and switch means from the debris of the cutting action.</p> |
