Abstract
Abstract Metal slabs coming hot from a rolling mill, in a more or less horizontal position, are fed into a set of pivotal jaws which erect them for engagement by a hoist clamp carrying each slab across a pool of cooling water for upright insertion into and removal from an assigned bay of a submerged rack. A further set of jaws at the other end of the pool returns the cooled slabs to a recumbent position preparatorily to further handling.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
A system for cooling hot metal slabs, comprising: a pool for the storage of cooling water provided with submerged bays for receiving such slabs in an upright position; a track spanning said pool; erecting means at one end of said track for turning hot oncoming slabs from a recumbent to an upright position; hoist means movable along said track for seizing an erected slab at said one end, lowering the erected slab into one of said bays and subsequently removing the slab in its upright position from said pool for transportation to the other end of said track; and unloading means at said other end for removing the cooled slab from said hoist means.
Claim 2
Independent Claim
114 words
A system for cooling hot metal slabs, comprising: a pool for the storage of cooling water provided with submerged bays for receiving such slabs in an upright position; a track spanning said pool; erecting means at one end of said track for turning hot oncoming slabs from a recumbent to an upright position; hoist means movable along said track for seizing an erected slab at said one end, lowering the erected slab into one of said bays and subsequently removing the slab in its upright position from said pool for transportation to the other end of said track; and unloading means at said other end for removing the cooled slab from said hoist means.
Claim 3
Dependent Claim
24 words
A system as defined in claim 1 wherein said unloading means includes swingable gripper means for returning the cooled slab to a recumbent position.
Claim 4
Dependent Claim
32 words
A system as defined in claim 2 wherein said erecting means and said gripper means each comprises a set of juxtaposed jaws rotatable in parallel planes through an arc Of substantially 90*.
Claim 5
Dependent Claim
45 words
A system as defined in claim 1 wherein said hoist means comprises a carriage and a bracket with a downwardly open vertical slot elevatably suspended from said carriage, said bracket being provided with retractable latch means for closing the open lower end of said slot.
Claim 6
Dependent Claim
64 words
A system as defined in claim 4 wherein said latch means comprises a member pivotably mounted on one side of said open end, spring means tending to withdraw said member from said open end, abutment means on the other side of said open end, and actuating means for moving said member into contact with said abutment means against the force of said spring means.
Claim 7
Dependent Claim
65 words
A system as defined in claim 5 wherein said bracket is provided with a recess at said one side adjacent said open end, said member being upwardly swingable by said spring means for withdrawal into said recess, said slot being of sufficient depth to receive said slab with top clearance enabling such withdrawal upon said slab coming to rest on a support alongside said bracket.
Claim 8
Dependent Claim
37 words
A system as defined in claim 1 wherein said pool is provided with a rack structure forming said bays, said structure including a set of parallel slab-supporting beams with upstanding teeth for accommodating the upright slabs therebetween.
Claim 9
Dependent Claim
43 words
A system as defined in claim 7, further comprising nozzle means in said pool below the level of said beams for the introduction of fresh cooling water, and drain means above the level of the slabs for removing spent water from said pool.
Claim 10
Dependent Claim
29 words
A system as defined in claim 1 wherein said pool is bounded by a pair of parallel walls, said track comprising a pair of rails supported by said walls.
Claim 11
Dependent Claim
39 words
A system as defined in claim 9 wherein said hoist means comprises a pair of cranes riding on said rails for respectively transporting slabs from said erecting means to said bays and from said bays to said unloading means.
