The hose reel illustrated herewith is arranged to have the hose always connected to the hydrant so that it may be reeled and unreeled to any extent desired, the surplus length of hose remaining on the reel. The writer has not tried out this scheme but merely offers it to the Handy Man as a suggestion. The details of the construction need little explanation as they are clearly shown in Fig. 303. The reel is mounted to revolve on a horizontal pipe. The hydrant pipe passes through the horizontal pipe and is connected by a swivel joint with another pipe attached to the hose. This provides a permanent connection between the hydrant and the hose which is in no way interfered with by revolving the reel.
