Abstract
A hose reel apparatus for garden and other type hoses which rewinds the hose after it has been pulled from the reel and automatically shuts off the flow of fluid through the hose and drains the fluid from the hose after it has been rewound. The apparatus includes a fluid motor powered by the fluid which is also directed through the hose, and fluid valving utilizing fluid pressure for stopping fluid flow through the hose. The valving is responsive to an increase in fluid pressure resulting from restriction in the rotation of the hose reel after the hose has been rewound.
Claims16
Hose reel apparatus comprising in combination, a cylindrical hose reel;
- support means for rotatably supporting said reel on an axis of rotation;
- winding means for directing and guiding a hose around and along said reel as said reel is rotated on said axis including fluid motive power means on said support means for rotating said reel about said axis;
- fluid valve means for controlling operation of said fluid motive power means and for controlling fluid flow to a hose on said reel when the hose is connected to said fluid valve means, said fluid valve means having a first fluid conducting means for admitting and directing fluid through the hose, a second fluid conducting means for directing said fluid through said fluid motive power means for rotating said reel to wind the hose on said reel prior to the passage of the fluid through the hose, and movable valve sealing means responsive to a fluid pressure increase for closing said first and second fluid conducting means and shutting off the flow of said fluid through said fluid motive power means and the hose on said reel;
- and fluid control means responsive to the winding of a predetermined amount of hose on said reel for providing an increase in fluid pressure in said fluid valve means whereby the increase in fluid pressure moves said valve sealing means to shut off fluid flow through the hose and stop rotation of said reel when the predetermined amount of the hose is wound on said reel.
Hose reel apparatus comprising in combination, a cylindrical hose reel;
- support means for rotatably supporting said reel on an axis of rotation;
- fluid motive power means on said support means for rotating said reel about said axis;
- guide means mounted for movement along the side of said reel generally parallel to said reel axis and engaging the side of said reel for receiving, guiding, and wrapping a hose evenly around and axially along said reel as it is rotated on said axis;
- fluid valve means for controlling a flow of fluid through the hose and for controlling a flow of fluid through said fluid motive power means to wind the hose on said reel including first fluid conduit means for directing said fluid through the hose, second fluid conduit means for directing said fluid into said fluid motive power means, movable valve sealing means responsive to a change in fluid pressure for shutting off the flow of fluid through said first and second fluid conduit means and thus the hose when said reel is prevented from rotating;
- and fluid control means for preventing rotation of said reel when a predetermined amount of hose is wound on said reel, said fluid control means including means responsive to said prevention of rotation of said reel for changing the fluid pressure in a portion of said fluid valve means whereby when said reel is prevented from rotating by said control means, said valve sealing means is moved to shut off fluid flow to both said hose and fluid motive power means.
In a hose reel apparatus of the type including a cylindrical hose reel, support means for supporting said hose reel for rotation about a rotational axis, means for rotating said reel about said axis to wind a hose thereon, and valve means for directing a fluid through the hose, the improvement comprising a hose receiving and guiding means for evenly winding the hose on said reel, said guiding means including a helical groove extending around and axially along said cylindrical reel, a support rod positioned parallel to said reel axis and spaced from said reel, and a guide member mounted for axial movement along said rod;
- said guide member including an annular convex section having a shape corresponding to the cross-sectional shape of said groove in mating engagement with one portion of said groove, an annular concave section flaring inwardly from said convex section and located adjacent another portion of said groove spaced a distance parallel to said reel axis from said one groove portion for engaging and guiding the hose, and a longitudinal bore extending transversely through said annular sections for receiving said rod whereby rotation of said reel with said helical groove moves said guide member along said rod to guide said hose into said reel.
Hose reel apparatus comprising in combination, a cylindrical hose reel;
- support means for rotatably supporting said reel on an axis of rotation;
- winding means for directing and guiding a hose around and along said reel as said reel is rotated including motive power means on said support means for rotating said reel about said axis;
- fluid valve means for controlling fluid flow to a hose on said reel when the hose is connected to said fluid valve means including fluid conducting means for admitting and directing fluid through the hose, movable valve sealing means responsive to a fluid pressure increase for closing said fluid conducting means and shutting off the flow of said fluid through the hose on said reel;
- and fluid control means responsive to the winding of a predetermined amount of hose on said reel for providing an increase in fluid pressure in said fluid valve means whereby the increase in fluid pressure moves said valve sealing means to shut off flow through said hose when a predetermined amount of the hose is wound on said reel.
