ABSTRACT:
Automatic cutting machines carry flame cutting torches in close proximity of a work piece and can force the torch into contact with an upturned cut away piece from the work piece, causing considerable damage to the cutting apparatus. The subject apparatus provides a break away torch holder having a housing surrounding a torch tube which is mounted in an adaptor. The adaptor has a pilot that matches a pilot seat in the housing. The pilot is held in the pilot seat by resilient means that allows the torch tube to move with respect to the housing when the torch strikes an upturned cut away piece. A switch means is provided to shut the cutting machine down when the torch tube means is in the housing. Sealing means is also provided to protect the piloting apparatus and switch means from the debris of the cutting action.
