Abstract
Abstract The present invention provides an assembly of vertical slabcasting molds in which each of a plurality of vertical molds in said assembly may be removed therefrom. The vertical molds are positioned over at least two sets of rails. Each of said molds is moved on at least two wheel assemblies. One of said wheel assemblies is on one set of rails and the other wheel assembly is on the other set of rails. Each set of rails contains at least two parallel tracks. Each wheel assembly moves on one track and the wheel assemblies of adjacent molds are positioned on adjacent tracks forming a staggered relationship relative to each other. Each wheel assembly moves on one track and is sufficiently low so that it may move under the vertical molds.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
An assembly of vertical slab-casting molds comprising a plurality of vertical molds assembled in side by side relationship, said vertical molds being positioned over at least two parallel sets of rails, with each set of rails disposed on opposite sides of the centerline of said molds, each of said molds supported by at least two wheel assemblies, one wheel assembly being on each set of rails, each set of rails comprising at least two parallel tracks, each of said wheel assemblies being wider than the mold supported thereon and having a front wheel and a rear wheel supported by one track and being of a sufficiently low height that they may move under said molds, and the wheel assemblies of adjacent molds are positioned on adjacent tracks forming a staggered relationship relative to each other.
Claim 2
Dependent Claim
135 words
An assembly of vertical slab-casting molds comprising a plurality of vertical molds assembled in side by side relationship, said vertical molds being positioned over at least two parallel sets of rails, with each set of rails disposed on opposite sides of the centerline of said molds, each of said molds supported by at least two wheel assemblies, one wheel assembly being on each set of rails, each set of rails comprising at least two parallel tracks, each of said wheel assemblies being wider than the mold supported thereon and having a front wheel and a rear wheel supported by one track and being of a sufficiently low height that they may move under said molds, and the wheel assemblies of adjacent molds are positioned on adjacent tracks forming a staggered relationship relative to each other.
Claim 3
Dependent Claim
49 words
The assembly of vertical molds of claim 1 wherein said rails are disposed substantially perpendicular to said molds and wherein the height of said wheel assemblies is adjusted to support said mold by insertion of shims between the tops of said wheel assembly and the bottom of said mold.
Claim 4
Dependent Claim
56 words
The assembly of vertical molds of claim 2 wherein an upright T-section rail is mounted between the parallel tracks of each of said set of rails, and wherein each of said wheel assemblies has a lateral projection in the direction of said T-section rail and positioned to engage under the upper flange of said T-section rail.
Claim 5
Dependent Claim
38 words
The assembly of vertical molds of claim 3 wherein said T-section rail is the upper portion of a double T-section rail having wide opposed bottom flanges which form the supporting surface upon which are mounted said parallel tracks.
Claim 6
Dependent Claim
30 words
The assembly of vertical molds of claim 4 wherein the central upright portion of the T-section rail functions as the guide means for controlling the movement of said wheel assemblies.
Claim 7
Dependent Claim
82 words
The assembly of vertical molds of claim 5 having at least two base support girders supporting said molds; having a back vertical wall mold positioned at the rear of the assembly and rigidly attached to the rear of said base support girders; and having tie rods in the upper portion of said assembly and positioned substantially across said vertical molds, whereby said base support girders and said tie rods function to support and transmit the forced utilized to brace the vertical molds.
Claim 8
Dependent Claim
22 words
The assembly of vertical molds of claim 6 wherein said tie rods Are pivotally mounted on said fixed back vertical wall mold.
Claim 9
Dependent Claim
27 words
The assembly of vertical molds of claim 7 having a movable front vertical wall mold which also functions as a stable thrust plate for supporting said assembly.
Claim 10
Dependent Claim
28 words
The assembly of vertical molds of claim 8 having hydraulic devices on at least the front or the back vertical mold to produce the force supporting said assembly.
Claim 11
Dependent Claim
23 words
The assembly of vertical molds of claim 9 wherein said hydraulic devices are pivotally mounted on the front of said base support girders.
