Description: |
| "Addition to GB-830,432. Headings B3B and B3C. The turn-table of the parent Specification is modified by the inclusion of fluid-pressure lifting jacks 16, 18 of equal, positively limited, stroke. Pressure-fluid from a pipe 8 is fed to the jacks through annular, radial and axial passages 9, 10, 11, 13 in the table-pivot 6, which also functions as a jack, assisting the jacks 16, 18 to raise the table-boss 4 and marginal flange clear of the cross-table 2. The jacks 16, 18 are mounted on the bearing 20-22, which is loosely connected by studs 23 to the cylinders 16." |
