ABSTRACT:
Penetrating nozzles are disclosed for first penetrating standard commercial and residential building materials to form a relatively small entrance hole or opening and subsequently delivering water to the area to cool off superheated gases. Different water dispersion attachments may be used, including a spiral or screw-type attachment for providing a mist or fog to the area or straight stream nozzles for directing a stream of water in directions either parallel to the axis of the nozzle or at an angle 90.degree. thereto. The nozzles include a protector cap at the leading axial end thereof which is provided with a tip suitable for battering the surfaces or barrier and punch a hole through it. The protector tip is retained on the tubular attachment until the protector tip has penetrated the barrier and has been placed on the other side, at which time the application of water under pressure to the elongate dial causes the protector tip to be cast off or ejected. Preferably, a retaining member, such as a still cable, continues to secure the protector tip to the elongate barrel so that it may be retrieved through the opening in the barrier for re-use. The protector tip can be used to penetrate concrete block, brick and mild steel, and may be variably configurated to best penetrate these materials. Advantageously, a battering block is provided at the other axial end of the elongate barrel suitable for battering the device against the barrier by means of a sledge hammer, flat ax and the like.
