    摘要： A cut-off device for a horizontally moving continuous casting includes a carriage assembly carrying a cut-off torch mechanism and a clamping mechanism. The assembly is mounted for reciprocable movement on a rod-like track which is open-ended to permit fast removal of the assembly for repairs. When the assembly is clamped to the moving casting, it is carried along therewith while the torch cuts through the casting to form billets of desired length. The track is floatingly mounted to permit deviation from the vertical by the casting without adversely affecting the cutting operation. The carriage assembly is tiltable on the track to permit horizontal deviation of the clamped casting. The torch is operated by a cam having a drop-off portion which quickly returns the torch to starting position. Upon release of the clamping mechanism, a damped counter-weight automatically returns the carriage assembly to its initial position on the track.

    摘要： A torch tip protector is elastically retained to an oxyacetylene cutting torch tip during transport. The torch tip protector in the preferred embodiment has a protector cap having a generally disc-shaped base and a truncated conical side wall that together form a cup or thimble-shaped torch tip cover. This torch tip cover operatively encompasses a torch tip and thereby operatively blocks access and fouling of the torch tip. To ensure that the protector cap stays engaged with torch tip, a hook secures to and is manually removable from at least one of the torch gas lines. A spring couples to the hook and couples with the protector cap to provide an elastic tension force that draws the protector cap towards hook and thereby secures the protector cap onto the torch tip.

    摘要： A novel cutting nozzle assembly for a postmixed oxygen-fuel gas torch is disclosed. The nozzle assembly includes a cylindrical shroud which surrounds and extends away from the gas discharge orifices in the gas discharge end of the cutting nozzle. The cylindrical shroud has the advantage of producing a tighter gas stream and of promoting a more thorough mixing of the preheat oxygen and the fuel gas to provide a hotter, more compact flame which produces a more parallel-sided cut through metal workpieces. The cutting tip therefore conserves metal as well as cutting gases. It also cuts faster than prior art postmixed cutting nozzles.
