Abstract

Abstract Apparatus for treating fabric with liquid in open width comprising a duct having an upper bounding wall and a lower bounding wall shaped so that the duct, considered in parallel vertical planes of section, has substantially the shape of an upright U, with the limbs terminating in an upwardly-open inlet and an upwardly-open outlet respectively, the bounding walls having numerous small openings through them at least over the central part of the U, the duct also having side walls, and there being dividing walls extending upwards from the upper bounding wall over the central part of the U, in planes substantially parallel to the side walls, the apparatus also comprising a vessel enclosing with clearance at least the lower part of the duct, and means for imparting to the duct a motion such that the central part of the U rises and falls repeatedly.

Claim 1
Independent Claim 144 words
Apparatus for treating fabric with liquid in open width comprising a duct having an upper bounding wall and a lower bounding wall shaped so that the duct, considered in parallel vertical planes of section, has substantially the shape of an upright U, with the limbs terminating in an upwardly-open inlet and an upwardly-open outlet respectively, the bounding walls having numerous small openings through them at least over the central part of the U, the duct also having side walls, and there being dividing walls extending upwards from the upper bounding wall over the central part of the U, in planes substantially parallel to the side walls, the apparatus also comprising a vessel enclosing with clearance at least the lower part of the duct, and means for imparting to the duct a motion such that the central part of the U rises and falls repeatedly.
Claim 2
Dependent Claim 144 words
Apparatus for treating fabric with liquid in open width comprising a duct having an upper bounding wall and a lower bounding wall shaped so that the duct, considered in parallel vertical planes of section, has substantially the shape of an upright U, with the limbs terminating in an upwardly-open inlet and an upwardly-open outlet respectively, the bounding walls having numerous small openings through them at least over the central part of the U, the duct also having side walls, and there being dividing walls extending upwards from the upper bounding wall over the central part of the U, in planes substantially parallel to the side walls, the apparatus also comprising a vessel enclosing with clearance at least the lower part of the duct, and means for imparting to the duct a motion such that the central part of the U rises and falls repeatedly.
Claim 3
Dependent Claim 28 words
Apparatus according to claim 1, including means by which the duct is mounted to swing relatively to the vessel about a horizontal transverse axis adjacent to its outlet.
Claim 4
Dependent Claim 24 words
Apparatus according to claim 1, in which the dividing walls define a wide central compartment flanked at each side by several narrower lateral compartments.
Claim 5
Dependent Claim 26 words
Apparatus according to claim 1, including transverse baffles extending from at least one of the underside of the duct and the bottom wall of the vessel.
Claim 6
Dependent Claim 31 words
Apparatus according to claim 1, in which the spacing between the upper and lower walls of the duct progressively increases from the inlet end to the outlet end of the duct.
