Abstract
Abstract An apparatus for quenching elongated extruded metal products is provided in which the metal products are extruded directly into an elongated open ended, open bottom enclosure in which a wall of coolant is formed and wherein the construction is such that a puller for said elongated extruded metal products can engage the end of such products immediately adjacent the extrusion die and can move through said enclosure while maintaining a seal for preventing escape of the coolant during such movement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
Apparatus for quenching elongated hot extruded products comprising: a. an elongated open ended, open bottom enclosure mounted with one open end immediately adjacent the orifice of an extrusion die, b. a table beneath said open bottom of said enclosure, c. means for introducing a liquid coolant into said enclosure, d. a catch basin for said liquid beneath said table, e. a puller for said elongated extruded metal products mounted within said enclosure over said table and adapted to grip one end of an elongated extruded metal product adjacent said extrusion die, f. motive means for moving said puller longitudinally over said table, g. a seal associated with said enclosure and said motive means for preventing escape of said liquid during the longitudinal movement of said puller away from said extrusion die, and h. means for moving said enclosure and the components connected thereto away from said table.
Claim 2
Dependent Claim
147 words
Apparatus for quenching elongated hot extruded products comprising: a. an elongated open ended, open bottom enclosure mounted with one open end immediately adjacent the orifice of an extrusion die, b. a table beneath said open bottom of said enclosure, c. means for introducing a liquid coolant into said enclosure, d. a catch basin for said liquid beneath said table, e. a puller for said elongated extruded metal products mounted within said enclosure over said table and adapted to grip one end of an elongated extruded metal product adjacent said extrusion die, f. motive means for moving said puller longitudinally over said table, g. a seal associated with said enclosure and said motive means for preventing escape of said liquid during the longitudinal movement of said puller away from said extrusion die, and h. means for moving said enclosure and the components connected thereto away from said table.
Claim 3
Dependent Claim
38 words
An apparatus as claimed in claim 1 in which (c) comprises means for introducing a liquid coolant to the interior of said enclosure from opposite sides of said enclosure to form a water wall around the extruded product.
Claim 4
Dependent Claim
25 words
An apparatus as claimed in claim 2 which comprises means for introducing a liquid coolant from the top of said enclosure to the interior thereof.
Claim 5
Dependent Claim
21 words
An apparatus as claimed in claim 1 in which (d) comprises means for catching liquid ovErflowing the sides of said table.
Claim 6
Dependent Claim
35 words
An apparatus as claimed in claim 1 which comprises means for transferring said liquid coolant from said catch basin to a reservoir and means for returning said liquid coolant from said reservoir to said enclosure.
Claim 7
Dependent Claim
194 words
Apparatus for quenching elongated hot extruded products comprising: a. an elongated open ended, open bottom enclosure mounted with one open end immediately adjacent the orifice of an extrusion die, b. a table beneath said open bottom of said enclosure, c. means for introducing a liquid coolant into said enclosure, d. a catch basin for said liquid beneath said table, e. a puller for said elongated extruded metal products mounted within said enclosure over said table and adapted to grip one end of an elongated extruded metal product adjacent said extrusion die, f. motive means for moving said puller longitudinally over said table comprising an inwardly extending arm, and g. a seal associated with said enclosure and said motive means for preventing escape of said liquid during the longitudinal movement of said puller away from said extrusion die comprising a flexible, water resistant and heat resistant sheet material depending downwardly from one side of said enclosure on said side of said table, the lower part of said sheet material being in contact with said arm of (f) as said puller moves through said enclosure and forming a seal to prevent the escape of said liquid.
Claim 8
Dependent Claim
194 words
