Abstract

A hose reel assembly including a housing of substantially cylindrical shaped configuration, a water inlet area axially disposed relative to the longitudinally axis of the cylinder, a transfer hose to allow communication of a fluid inlet to the hose disposed upon an associated reel contained within the housing, a spring associated between a stationary portion of a reel support spindle and the hose reel to resist rotation and paying out of the hose, a pawl and ratchet mechanism intermittantly engageable along a certain periphery of the ratchet to selectively enable and disable the ratchet mechanism against the spring, and a squeegie mechanism associated with an outlet of the hose which allows removal of water within the hose upon retraction of the hose within the housing in the absence of fluidic pressure.

Claims

1. A hose reel assembly comprising in combination:

a housing having an interior adapted to receive therein a plurality of hose wraps looped over a central supporting drum,

inlet means to provide fluid communication between a source of water and the hose disposed thereon,

a hose outlet extending through an opening within the housing,

squeegie means sensitive to fluidic pressure of the water system whereby in the absence of fluidic pressure said squeegie means is enabled so that when the hose is retracted back into said housing water is purged from the hose,

said squeegie means being assisted in purging by means of a spring biasing between said hose supporting drum and a stationary axle during the retraction period, and

said squeegie means includes a bracket disposed on an outer face of said housing having a radially outwardly extending wiper, a further wiper depending from said first wiper and biased thereto, the hose extending therebetween, whereby said biasing allows the squeegie to operate in the absence of water pressure.

2. A hose reel assembly comprising in combination:

a housing having an interior adapted to receive therein a plurality of hose wraps looped over a central supporting drum,

inlet means to provide fluid communication between a source of water and the hose disposed thereon,

a hose outlet extending through an opening within the housing,

squeegie means sensitive to fluidic pressure of the water system whereby in the absence of fluidic pressure said squeegie means is enabled so that when the hose is retracted back into said housing water is purged from the hose,

said squeegie means being assisted in purging by means of a spring biasing between said hose supporting drum and a stationary axle during the retraction period,

said drum spring being resisted by a selectively engageable pawl carried on said drum and ratchet means on said axle,

said hose inlet communicating with the hose disposed upon said drum by means of a transfer hose having a swivel and threaded outlet communicating with the hose inlet and a radially extending passageway communicating with a longitudinally extending portion underlying the wrapped hose and overlying a drum supporting surface, whereby rotation of said drum does not twist the hose,

said drum including a hose support surface connected to a rotating axle, said hose supporting surface including hose support sidewalls extending upwardly therefrom, a passageway extending between said hose support sidewalls and said hose support surface for admission therein of said transfer hose, and a further web extending between said hose support surface and said stationary axle separated from said stationary axle by a bearing,

said stationary axle being formed integrally with said housing, said rotating axle carried on said stationary axle by means of a bearing, said housing formed from first and second sidewalls of substantially circular configuration having a hose feed side and a ratchet side and an annular end wall circumscribing the outer periphery of said sidewalls,

said ratchet means including a spring connected between said web and a pivot post on said web, said pivot post including a pawl overlying said pivot post having an end communicating with gear teeth disposed on a ratchet gear, said ratchet gear carried on said stationary axle and fixed thereto, whereby rotation of said web indexes said pawl against said teeth,

said ratchet wheel including a void area on an outer periphery thereof defining absence of teeth to allow release of said pawl and ratchet assembly,

wherein said squeegie means includes a bracket disposed on an outer face of said housing having a radially outwardly extending wiper, a further wiper depending from said first wiper and biased thereto, the hose extending therebetween whereby said biasing allows the squeegie to operate in the absence of water pressure.

3. A hose reel assembly comprising in combination:

a housing having an interior within which a hose drum is carried,

a centrally disposed stationary shaft integrally formed with said housing communicating with a coaxial rotating axle through a bearing,

said housing communicating with said rotating axle through a bearing,

said rotating axle carrying said hose drum thereon through a web means,

said rotating axle and stationary axle coaxially related defining a split axle to allow relative rotation of said drum relative to said housing,

a water inlet axially disposed communicating with hose disposed on said drum and an outlet through said housing allowing another end of the hose to pass therethrough

whereby hose can be paid in and out of said housing interior and on said drum,

a squeegie mechanism disposed overlying the outlet opening and straddling the hose, said squeegie mechanism provided with biasing means overriden by fluidic pressure, and wherein said squeegie means includes a U-shaped bracket having an outwardly extending overlying wiper and a depending wiper of substantially L-shaped configuration straddling the outlet portion of the hose, and biasing means extending therebetween conditioned by water pressure.

4. A hose reel assembly comprising in combination:

a housing having an interior within which a hose drum is carried,

a centrally disposed stationary shaft integrally formed with said housing communicating with a coaxial rotating axle through a bearing,

said housing communicating with said rotating axle through a bearing,

said rotating axle carrying said hose drum thereon through a web means,

said rotating axle and stationary axle coaxially related and defining a split axle to allow relative rotation of said drum relative to said housing,

a water inlet axially disposed communicating with hose disposed on said drum and an outlet through said housing allowing another end of the hose to pass therethrough,

whereby hose can be paid in and out of said housing interior and on said drum,

said drum operating against a spring extending between a hose supporting surface and said stationary axle, ratchet means opposing rotation of said spring, whereby indexing of said drum can be afforded,

wherein said assembly includes a squeegie mechanism disposed overlying the outlet opening and straddling the hose, said squeegie mechanism provided with biasing means overriden by fluidic pressure.

said ratchet means including a pawl carried on and rotating with said drum, a ratchet gear fixed on said stationary axle, said pawl biased with a spring extending between said pawl and said rotating drum, a portion of said ratchet teeth interrupted on an outer periphery of said ratchet wheel to allow selective disabling of said pawl and ratchet for rewinding and allowing said drum spring to work,

wherein said squeegie means includes a U-shaped bracket having an outwardly extending overlying wiper and a depending wiper of substantially L-shaped configuration straddling the outlet portion of the hose, and biasing means extending therebetween conditioned by water pressure.

5. The device of claim 4 including a carry handle carried on an outer periphery of said housing, said housing formed from said first and second sidewalls of substantially circular configuration and an annular arcuate end wall circumscribing said sidewalls.
