Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
67 words
Apparatus for cooling wire rod, comprising an upright substantially cylindrical container for an aqueous bath, said container having a height substantially greater than its width, means to bend wire rod of indeterminate length into a series of open loops, means to introduce said loops after bending into the bath in a downward direction, and means to remove the loops laterally from the lower end of the bath.
Claim 2
Dependent Claim
67 words
Apparatus for cooling wire rod, comprising an upright substantially cylindrical container for an aqueous bath, said container having a height substantially greater than its width, means to bend wire rod of indeterminate length into a series of open loops, means to introduce said loops after bending into the bath in a downward direction, and means to remove the loops laterally from the lower end of the bath.
Claim 3
Dependent Claim
14 words
Apparatus as claimed in claim 1, said height being more than twice said width.
Claim 4
Dependent Claim
63 words
Apparatus as claimed in claim 1, said means for laterally removing the loops comprising conveyor means extending outside said container upwardly from adjacent the lower end of the bath to a level at least as high as the surface of the bath, and means beyond said conveyor means for collecting said loops and for assembling said loops into a roll of wire rod.
Claim 5
Dependent Claim
65 words
Apparatus as claimed in claim 1, said means to remove the loops comprising an inclined conveyor whose lower end is disposed at the lower end of the bath to receive the loops, and a casing outside said container, said conveyor being disposed in said casing, said casing having an upper end at least as high as the level of the liquid bath in said container.
Claim 6
Dependent Claim
12 words
Apparatus as claimed in claim 4, said container being outside said casing.
Claim 7
Dependent Claim
24 words
Apparatus as claimed in claim 1, said wire rod emerging from said bending means at a level above the liquid level of said bath.
