7 Claims. (Cl. 254-190)
Broadly stated, our invention appertains to a hose guide
in which two rings so mounted that the planes thereof
are parallel are used as bearings for the wheels or rollers.
In the preferred embodiment of the invention the device
is equipped with a quick acting clamping means which
may be locked in the closed position and easily unlocked
