Abstract
Abstract A wire passing upwardly after having passed through a molten metal coating bath is contacted with a moving stream of water jetting upwardly through the atmosphere at an angle. The stream of water and the moving wire meet just at the apex of the stream where the energy of movement of the water is least. The cooling stream of water thus causes a minimum disturbance of the still molten coating on the wire.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
Apparatus for cooling moving molten material coated wire-like material comprising: a. a cooling chamber defining a vertical path for said wire-like material, b. means to form at least one liquid cooling jet within said cooling chamber, said means being arranged to direct said cooling jet as a discrete free stream of liquid upwardly at an angle other than vertically with the path of said stream intersecting the path of said wire-like material at the apex of the path of said discrete stream of cooling liquid where substantially all vertical components of the movement of said stream is dissipated, c. said means for forming said liquid cooling jet comprising header means for conveying cooling liquid from an external source into the vicinity of the cooling chamber and nozzle means connected to the header means and inclined upwardly at an angle such that a stream of cooling liquid ejected from the nozzle means is projected upwardly at an angle such that the stream of coolant intersects the path of the wire-like material at the apex of the stream of coolant just prior to beginning to fall in a descending arc downwardly from the said apex, and d. means to collect said descending coolant.
Claim 2
Dependent Claim
201 words
Apparatus for cooling moving molten material coated wire-like material comprising: a. a cooling chamber defining a vertical path for said wire-like material, b. means to form at least one liquid cooling jet within said cooling chamber, said means being arranged to direct said cooling jet as a discrete free stream of liquid upwardly at an angle other than vertically with the path of said stream intersecting the path of said wire-like material at the apex of the path of said discrete stream of cooling liquid where substantially all vertical components of the movement of said stream is dissipated, c. said means for forming said liquid cooling jet comprising header means for conveying cooling liquid from an external source into the vicinity of the cooling chamber and nozzle means connected to the header means and inclined upwardly at an angle such that a stream of cooling liquid ejected from the nozzle means is projected upwardly at an angle such that the stream of coolant intersects the path of the wire-like material at the apex of the stream of coolant just prior to beginning to fall in a descending arc downwardly from the said apex, and d. means to collect said descending coolant.
Claim 3
Dependent Claim
43 words
Apparatus for cooling wire-like material according to claim 1 wherein the liquid cooling jet is comprised of a single undivided stream of liquid adapted to cool the wire-like material with a gentle laminar flow of liquid past the surface of the wire-like material.
Claim 4
Dependent Claim
32 words
Apparatus for cooling wire-like material according to claim 2 wherein there are means establishing a multiplicity of liquid cooling jets along the line of travel of the wire-like material through said chamber.
Claim 5
Dependent Claim
19 words
Apparatus for cooling moving wire-like material according to claim 1 wherein the liquid cooling jet is comprisEd of water.
Claim 6
Dependent Claim
34 words
Apparatus for cooling moving wire-like material according to claim 4 wherein the cooling chamber of (a) is preceded by a forced air cooling means impinging streams of relatively cool air upon said linear material.
Claim 7
Dependent Claim
32 words
Apparatus for cooling moving wire-like material according to claim 5 wherein the cooling chamber of (a) is followed by a vibration damping means physically contacting the wire-like material adjacent to said chamber.
