Abstract
Abstract A conventional continuous-casting mold oscillates vertically. Invention is an improved guide mechanism for maintaining the mold in alignment with parts beneath and holding the mold firmly as it oscillates. The frame which carries the mold has vertically extending guide rails of hollow V-shape in cross section on opposite sides. Rails are engaged by rollers, one of which is spring mounted. Hold-down rods for the oscillating mold frame extend lengthwise through the rails.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
In a continuous-casting machine which includes a vertically movable inner frame, a stationary outer frame in which said inner frame is mounted, an open-ended water-cooled mold carried by said inner frame, and a cam mechanism carried by said frames for oscillating said inner frame, the combination therewith of an improved guide mechanism comprising a pair of rails which are of V-shape in cross section and extend vertically along opposite sides of said inner frame, said rails having bearing surfaces which lie at right angles to each other and at 135* to the faces of the inner frame, and upper and lower banks of rollers carried by said outer frame and engaging said bearing surfaces near their upper and lower ends respectively.
Claim 2
Dependent Claim
121 words
In a continuous-casting machine which includes a vertically movable inner frame, a stationary outer frame in which said inner frame is mounted, an open-ended water-cooled mold carried by said inner frame, and a cam mechanism carried by said frames for oscillating said inner frame, the combination therewith of an improved guide mechanism comprising a pair of rails which are of V-shape in cross section and extend vertically along opposite sides of said inner frame, said rails having bearing surfaces which lie at right angles to each other and at 135* to the faces of the inner frame, and upper and lower banks of rollers carried by said outer frame and engaging said bearing surfaces near their upper and lower ends respectively.
Claim 3
Dependent Claim
64 words
A combination as defined in claim 1 in which the banks of rollers at one side of said outer frame include respective bearing lugs, rollers journaled in said bearing lugs, one of said bearing lugs being fixed with respect to said outer frame, and adjustable spring means urging said other bearing lug to a position in which the roller journaled therein contacts the rail.
Claim 4
Dependent Claim
36 words
A combination as defined in claim 1 in which said rails are hollow and including hold-down rods extending upwardly from said outer frame and lengthwise through said rails, and springs encircling said rods above said rails.
Claim 5
Dependent Claim
138 words
A combination as defined in claim 1 including inwardly extending brackets mounted on opposite sides of said outer frame, and pairs of upstanding plates carried by the respective brackets and having faces lying parallel with the bearing surfaces of said rails, and in which the banks of rollers at one side of said outer frame include respective bearing lugs fixed to the plates at that side and rollers journaled in said bearing lugs, and thE banks of rollers at the other side of said outer frame include a bearing lug fixed to one plate at that side and a bearing lug movably mounted on the other plate at that side, rollers journaled in said latter bearing lugs and adjustable spring means urging the last-named bearing lug to a position in which the roller journaled therein contacts the rail.
Claim 6
Dependent Claim
18 words
A combination as defined in claim 4 including shims mounted between the fixed bearing lugs and their plates.
