Abstract
Abstract This specification discloses an apparatus for freezing the molten zinc coating on a moving wire after it issues from a wiping box for controlling the coating, comprising two or more water discharge passages for forming jets of water spaced along and transversely intersecting the line of movement of the wire, said jets being controlled whereby the flow of water in each jet is non-turbulent, and an air discharge duct having a narrow discharge slit for creating a flow of air directed transversely to the line of movement of the wire between said jets and the wiping box.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
149 words
An apparatus for cooling and solidifying coatings on moving wires, the coating having been applied by a coating apparatus from which the wire passes upwardly, comprising at least one liquid discharge passage for forming a jet of cooling liquid intersecting the line of movement of the wire from the coating apparatus, at which point the coating is still in the liquid state, and having a height substantially greater than its width, means for controlling the jet issuing from said at least one passage whereby the flow of liquid is non-turbulent so that the coating is solidified while it remains substantially smooth and uniform, and an air discharge duct having a horizontal narrow discharge slit for creating a flow of air directed transversely to the line of movement of the wire between the cooling apparatus and the coating apparatus for preventing the entry of cooling liquid into the coating apparatus.
Claim 2
Independent Claim
149 words
An apparatus for cooling and solidifying coatings on moving wires, the coating having been applied by a coating apparatus from which the wire passes upwardly, comprising at least one liquid discharge passage for forming a jet of cooling liquid intersecting the line of movement of the wire from the coating apparatus, at which point the coating is still in the liquid state, and having a height substantially greater than its width, means for controlling the jet issuing from said at least one passage whereby the flow of liquid is non-turbulent so that the coating is solidified while it remains substantially smooth and uniform, and an air discharge duct having a horizontal narrow discharge slit for creating a flow of air directed transversely to the line of movement of the wire between the cooling apparatus and the coating apparatus for preventing the entry of cooling liquid into the coating apparatus.
Claim 3
Dependent Claim
72 words
An apparatus according to claim 1, wherein two at least two passages are arranged in a linear array positioned along the line of movement of the wire said passages having their discharge ends adjacent each other whereby the individual streams merge into a single non-turbulent jet having a height greater than its width, said jet being directed transversely to the line of wire movement in the region of intersection with the wire.
Claim 4
Dependent Claim
90 words
An apparatus according to claim 1, wherein a single discharge passagE forms a non-turbulent jet of water flowing in the direction of wire movement, said jet being coaxial with the line of wire movement for a large part of its height, a liquid recovery tube spaced from said passage in the direction of wire movement and having its axis directed transversely of the line of wire movement, suction means connected to the recovery tube for creating a stream of air into the tube and into which said jet is entrained.
Claim 5
Dependent Claim
54 words
An apparatus according to claim 2, wherein there are several linear arrays of discharge passages arranged in spaced relation along the line of movement of the wire, the passages in each array being restricted or obstructed to a different degree whereby the individual streams from the passages combine to form a single non-turbulent jet.
Claim 6
Dependent Claim
67 words
An apparatus according to claim 2, wherein the discharge passages in said array are arranged one above the other, said passages being connected to a water supply manifold with the lowermost passage at the discharge end being the uppermost passage at the manifold, each passage being restricted or obstructed to a different degree whereby the individual streams from the passages combine to form a single non-turbulent jet.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 1 wherein, said at least one discharge passage has a rectangular bore, the major dimensions of the bore being oriented transversely of the direction of wire movement.
Claim 8
Dependent Claim
41 words
An apparatus for cooling simultanesouly the coatings on several parallel wires in substantially the same plane, comprising a plurality of cooling apparatus as defined in claim 1 arranged side-by-side, the streams in said apparatus being laterally merged into a single jet.
Claim 9
Independent Claim
142 words
An apparatus for cooling and solidifying coating on moving wires, the coating having been applied by a coating apparatus from which the wire passes upwardly, at least two liquid discharge passages for forming jets of cooling liquid spaced along and transversely intersecting the line of movement of the wire from the coating apparatus, at which point the coating is still in the liquid state, means for controlling the jets issuing from said passages whereby the flow of liquid in each jet is non-turbulent so that the coating is solidified while it remains substantially smooth and uniform, and an air discharge duct having a horizontal narrow discharge slit for creating a flow of air directed transversely to the line of movement of the wire between the cooling apparatus and the coating apparatus for preventing the entry of cooling liquid into the coating apparatus.
Claim 10
Independent Claim
142 words
An apparatus for cooling and solidifying coating on moving wires, the coating having been applied by a coating apparatus from which the wire passes upwardly, at least two liquid discharge passages for forming jets of cooling liquid spaced along and transversely intersecting the line of movement of the wire from the coating apparatus, at which point the coating is still in the liquid state, means for controlling the jets issuing from said passages whereby the flow of liquid in each jet is non-turbulent so that the coating is solidified while it remains substantially smooth and uniform, and an air discharge duct having a horizontal narrow discharge slit for creating a flow of air directed transversely to the line of movement of the wire between the cooling apparatus and the coating apparatus for preventing the entry of cooling liquid into the coating apparatus.
Claim 11
Dependent Claim
51 words
An apparatus according to claim 8, wherein said liquid discharge passages are arranged on both sides of the line movement of the wire and are staggered with respect to each other whereby the jets impinge on both sides of the wire and the respective jets do not interfere with each other.
Claim 12
Dependent Claim
31 words
An apparatus according to claim 8 wherein said at least two discharge passages have rectangular bores, the major dimensions of the bores being oriented transversely of the direction of wire movement.
Claim 13
Dependent Claim
41 words
An apparatus for cooling simultaneously the coatings on several parallel wires in substantially the same plane, comprising a plurality of cooling apparatus as defined in claim 8 arranged side-by-side, the streams in said apparatus being laterally merged into a single jet.
Claim 14
Dependent Claim
38 words
An apparatus for cooling simultaneously the coating on several parallel wires in substantially the same plane, comprising a plurality of cooling apparatus according to claim 8 arranged side-by-side, the lowermost streams being laterally merged into a single jet.
