Abstract
Abstract A valve means for reversing the flow of processing fluid through packages of yarn or the like while the packages are mounted on the perforated spindles of a conventional carrier, the latter in turn being contained in a kier or other like treatment vessel. The valve means includes a valve chamber centrally located at the base of the kier. The valve chamber is surrounded by the radially spaced wall of a valve housing and the relationship of these components is such that the upper and lower ends of the valve chamber are in communication respectively with the perforated carrier spindles and the valve housing. The valve housing is in turn in communication with the interior of the kier. Inlet and outlet conduits for the processing fluid extend through the wall of the valve housing into communication with the valve chamber, and a butterfly valve in the valve chamber is adjustable to place the inlet conduit in communication with either the upper or lower end of the valve chamber.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
Apparatus for the fluid treatment of package material comprising in combination: a kier adapted to contain a carrier member, said carrier member having a plurality of perforated circumferentially spaced upstanding spindles on which the packages of material to be treated are vertically mounted; a valve chamber centrally located at the base of said kier; a valve housing surrounding said valve chamber, the upper and lower ends of said valve chamber being in communication respectively with the perforated spindles on said carrier and said valve housing, said valve housing in turn being in communication with the interior of said kier, inlet and outlet conduits for the treatment fluid, said conduits extending through said valve housing into communication with said valve chamber; and, a valve member in said valve chamber, said valve member being adjustable to direct the flow of fluid entering the apparatus through said inlet conduit either to the upper or lower ends of said valve chamber.
Claim 2
Dependent Claim
157 words
Apparatus for the fluid treatment of package material comprising in combination: a kier adapted to contain a carrier member, said carrier member having a plurality of perforated circumferentially spaced upstanding spindles on which the packages of material to be treated are vertically mounted; a valve chamber centrally located at the base of said kier; a valve housing surrounding said valve chamber, the upper and lower ends of said valve chamber being in communication respectively with the perforated spindles on said carrier and said valve housing, said valve housing in turn being in communication with the interior of said kier, inlet and outlet conduits for the treatment fluid, said conduits extending through said valve housing into communication with said valve chamber; and, a valve member in said valve chamber, said valve member being adjustable to direct the flow of fluid entering the apparatus through said inlet conduit either to the upper or lower ends of said valve chamber.
Claim 3
Dependent Claim
73 words
The apparatus as claimed in claim 1 wherein said valve chamber is defined by a first cylindrical wall member and said valve housing is comprised of a second cylindrical wall member, the lower end of which is enclosed by a Bottom member, the said first and second wall members being radially spaced to define an annular passageway therebetween, the said bottom member being spaced below the lower end of said first wall member.
Claim 4
Dependent Claim
62 words
The apparatus as claimed in claim 1 wherein the base of said carrier member is comprised of a manifold chamber in communication with each said upstanding perforated spindles, the lower end of said manifold chamber terminating in a downwardly disposed tubular extension which is inserted into the upper end of said valve chamber when said carrier member is contained within said kier.
Claim 5
Dependent Claim
67 words
The apparatus as set forth in claim 3 further characterized by the manifold chamber on said carrier member being defined by a wall, a portion of said wall being spaced from and parallel to the wall of said kier to thereby define a continuation of the said annular passageway, the said continuation terminating in an annular opening surrounding the vertically disposed perforated spindles on said carrier member.
Claim 6
Dependent Claim
50 words
The apparatus as claimed in claim 4 further characterized by said inlet and outlet conduits extending through said second wall member into communication respectively with oppositely disposed inlet and outlet ports in said first wall member, the said valve member being adjustably mounted in said valve chamber between said ports.
Claim 7
Dependent Claim
44 words
The apparatus as claimed in claim 5 wherein said valve member is comprised of a disc mounted for pivotal movement about an axis which extends transversely to a reference line passing through the centers of the oppositely disposed ports in said first wall member.
Claim 8
Dependent Claim
99 words
The apparatus as claimed in claim 6 further characterized by operating means for pivotally adjusting said disc about said axis from a first position wherein the circumferential edge of said disc sealingly engages the interior of said first wall member to thereby place said inlet and outlet ports in communication respectively with the upper and lower ends of said valve chamber, and a second position wherein said disc again sealingly engages the interior of said first wall member, with the inlet and outlet ports thus being in communication respectively with the lower and upper ends of said valve chamber.
Claim 9
Dependent Claim
32 words
The apparatus as set forth in claim 6 further characterized by circumferentially spaced fin members in said annular passageway, the said fin members extending radially between said first and second wall members.
