Abstract
Abstract A support for a flexible heated dispensing hose comprising a hollow cylinder having opposite ends. A bracket attaches the cylinder to the dispenser. A helical spring is contained within the cylinder and extends beyond the opposite ends thereof. The hose is supported by the spring and cylinder so that the hose is free to move from side to side, the hose is prevented from kinking, abrasion of the hose against the cylindrical member is reduced, and optimum ventilation of the hose is provided.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
91 words
A fluid applicator comprising: a means for providing a pressurized supply of fluid; a flexible hose having one end connected to said providing means and the other end connected to a dispenser; a cylindrical tube mounted to said applicator, a helical spring positioned within said tube, said spring being of such a length so that the free ends thereof extend beyond each end of said tube and being less than the length of said hose; and said hose passing through said spring, said spring supporting said hose away from said tube.
Claim 2
Dependent Claim
91 words
A fluid applicator comprising: a means for providing a pressurized supply of fluid; a flexible hose having one end connected to said providing means and the other end connected to a dispenser; a cylindrical tube mounted to said applicator, a helical spring positioned within said tube, said spring being of such a length so that the free ends thereof extend beyond each end of said tube and being less than the length of said hose; and said hose passing through said spring, said spring supporting said hose away from said tube.
Claim 3
Dependent Claim
31 words
The fluid applicator of claim 1 wherein said hose is spaced from the ends of said tube so that the hose is not kinked about the proximate end of said tube.
Claim 4
Dependent Claim
27 words
The fluid applicator of claim 1 wherein said spring slidingly contacts the ends of said tube so that the hose is not abraided upon the movement thereof.
Claim 5
Dependent Claim
23 words
The fluid applicator of claim 1 wherein the spring supports said hose so that the hose is free to move side to side.
Claim 6
Dependent Claim
31 words
The fluid applicator of claim 1 said spring is adjustably positioned within said tube so that the length of said spring extending beyond each end of said tube may be selected.
Claim 7
Dependent Claim
116 words
A fluid applicator comprising: a means for providing a pressurized supply of fluid; a flexible hose having one end connected to said providing means and the other end connected to a dispenser; a cylindrical tube mounted to said applicator, a helical spring positioned within said tube, said spring being of such a length so as to extend beyond each end of said tube; and said hose passing through said spring, said spring supporting said hose away from said tube so that the entire circumference of that portion of said hose contained within said tube is spaced apart from the interior surface of said tube so that air may flow between said hose and said interior surface.
Claim 8
Dependent Claim
116 words
A fluid applicator comprising: a means for providing a pressurized supply of fluid; a flexible hose having one end connected to said providing means and the other end connected to a dispenser; a cylindrical tube mounted to said applicator, a helical spring positioned within said tube, said spring being of such a length so as to extend beyond each end of said tube; and said hose passing through said spring, said spring supporting said hose away from said tube so that the entire circumference of that portion of said hose contained within said tube is spaced apart from the interior surface of said tube so that air may flow between said hose and said interior surface.
