ABSTRACT:
A hose dispenser has a rotatable reel10, holding a coiled hose12suitable for conveying breathable gas, mounted on a tubular steel frame14. The reel has a pivoting arm16, which has a portion defining an aperture, or “eye”18fitted thereon. The hose is threaded through the eye16so that the free end of the hose protrudes through the eye. The free end of the hose is fitted with a resilient frusto-conical protective hood20. The hood provides two functions. First, it enables the free end of the hose to engage the eye of the arm16, and secondly, it protects a valve22, located on the free end of the hose, from damage. Another valve24is provided in the centre of the reel, which is connected to the other end of the hose. In use, the free end of the hose is carried by an operative, or is attached to breathing apparatus worn by the operative, and the other end is connected to a source containing gas for breathing. The arm16is mounted pivotally on the reel. Due to the fact that the hose is threaded through the aperture portion mounted on the arm, when the hose is put under tension, i.e. when the end of the hose is pulled so as to uncoil the hose, the arm lifts. If the hose becomes slack, i.e. when it is not being pulled, the arm falls under gravity. The pivoting arm16is operatively connected to braking means which provides a brake for the reel10holding the hose. When the brake is engaged rotational motion of the reel is inhibited, thus preventing undesirably large amounts of hose from being dispensed from the reel10when the hose is slack.
