Abstract:
1. A hose reel assembly for cleaning tubes, said assembly comprising: a base; an inner drum mounted on the base; a generally tubular outer drum mounted on the base and surrounding the inner drum; a gap defined between a longitudinally aligned peripheral wall of the inner drum and a longitudinally aligned peripheral wall of the outer drum; and wherein the gap is adapted to receive a length of hose therein; and a first motor assembly operationally engaged with the inner drum; and wherein said first motor assembly is selectively operable to rotate the inner drum about a longitudinal axis in one of a first direction and a second direction; wherein the outer drum includes a first drum plate and a second drum plate, and the peripheral wall of the outer drum extends between the first and second drum plates and has an exterior surface and an interior surface; and wherein the first and second drum plates and the outer drum peripheral wall bound and define a first chamber; wherein the inner drum is received within the first chamber and includes a first inner drum plate and a second inner drum plate, and the peripheral wall of the inner drum extends between the first and second inner drum plates; and wherein the first and second inner drum plates and the inner drum's peripheral wall bound and define a second chamber therein; and the first inner drum plate is disposed inwardly from and proximate to the first drum plate and the second inner drum plate is disposed inwardly from and proximate to the second drum plate, and the peripheral wall of the inner drum has an exterior surface and an interior surface, and the exterior surface of the inner drum's peripheral wall is separated from the interior surface of the outer drum's peripheral wall by the gap; a groove is defined in the interior surface of the outer drum's peripheral wall, said groove being adapted to receive the hose therein when the hose is disposed in the gap; wherein the peripheral wall of the inner drum comprises a plurality of independently rotatable tubular members extending longitudinally between the first and second inner drum plates, and said tubular members are positioned at intervals around a circumferential edge of both of the first and second inner drum plates with adjacent tubular members being separated from each other by a space; and wherein two pairs of adjacent tubular members disposed opposite each other are each spaced apart by an enlarged space that is greater in circumferential size than the spaces between all other adjacent pairs of tubular members; and wherein the hose reel assembly further includes: a feed mechanism disposed within the second chamber of the inner drum, wherein the feed mechanism is adapted to wind the length of hose disposed in the gap into an exterior surface of the inner drum's peripheral wall when the inner drum is rotated in the first direction, or to wind the length of hose off of the exterior surface of the inner drum's peripheral wall as the inner drum is rotated in the second direction; and wherein the feed mechanism includes:
