Abstract
Abstract A liquid distributing device, which is particularly suitable for the application of a viscous liquid to a rotating elongated object, consisting essentially of a rotatable annular drum provided on its external surface with scooping means to take up a liquid from a container and in its interior with means to deposit liquid which is taken up by the scooping means and transferred to the interior on the surface of an object located in or passing through the drum when the drum is rotated. In the production of fiberglass-resin pipe, glass fiber material is laid onto a rotating cylindrical support, and the glass fiber material is coated with a polyester resin by passing the rotating support through a liquid distributing device from which the resin is deposited.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
250 words
A liquid distributing device comprising a rotatable annular drum having an external surface provided with scooping means to take up a liquid from a container and an interior provided with means whereby liquid which is taken up by the scooping means and transferred to the interior is deposited on the surface of an object located in or passing through the drum when the drum is rotated, the drum having a first sidewall with an external surface thereof having two diametrically aligned dove-tail projections, a first ring coupled to the sidewall, said ring having in a surface thereof slots in which the projections of the sidewall are slidably accommodated and on another surface thereof two aligned dove-tail projections, a second ring coupled to the first ring, the second ring having in a surface thereof slits in which the projections of the first ring are slidably accommodated, the projections of the first ring and slots of the second ring being at an angle of about 90* to the projections of said sidewall and the slots of the first ring, and the drum having attached thereto on the other sidewall thereof an annular wiper which bears against an object passing through the drum whereby when a rotating object passes through the drum and comes into contact with the wiper, any localized pressure on the wiper caused by eccentricity of rotation of the object causes a compensating movement between the dove-tail projections of the first sidewall or the first ring and the corresponding slots.
Claim 2
Dependent Claim
250 words
A liquid distributing device comprising a rotatable annular drum having an external surface provided with scooping means to take up a liquid from a container and an interior provided with means whereby liquid which is taken up by the scooping means and transferred to the interior is deposited on the surface of an object located in or passing through the drum when the drum is rotated, the drum having a first sidewall with an external surface thereof having two diametrically aligned dove-tail projections, a first ring coupled to the sidewall, said ring having in a surface thereof slots in which the projections of the sidewall are slidably accommodated and on another surface thereof two aligned dove-tail projections, a second ring coupled to the first ring, the second ring having in a surface thereof slits in which the projections of the first ring are slidably accommodated, the projections of the first ring and slots of the second ring being at an angle of about 90* to the projections of said sidewall and the slots of the first ring, and the drum having attached thereto on the other sidewall thereof an annular wiper which bears against an object passing through the drum whereby when a rotating object passes through the drum and comes into contact with the wiper, any localized pressure on the wiper caused by eccentricity of rotation of the object causes a compensating movement between the dove-tail projections of the first sidewall or the first ring and the corresponding slots.
Claim 3
Dependent Claim
26 words
A device according to claim 1, in which the means by which the liquid is deposited comprises baffles disposed in the drum between opposite sidewalls thereof.
Claim 4
Dependent Claim
33 words
A device according to claim 1 in which the wiper has a flanged portion to extend substantially in the direction of movement of the surface of the object and bear against said surface.
Claim 5
Dependent Claim
24 words
A device according to claim 1, in which the wiper is fitted to the drum and supported in position by an annular backing member.
