Description: |
| "A horizontal boring &c. machine comprises a turntable 4 and a fluid-operated jack 8, 9 for lifting the table clear of the cross-table &c. 3 to facilitate its rotation. A pivot 5 on the turntable 4 bears in the cross-table, and a ballbearing 7 is located between the pivot and the piston 8. An actuator cylinder 12 supplies the jack. Clamping means, such as those described in Specification 966,737 for clamping the turntable to the cross-table, are interlocked, as by an abutment-operated electrical switch, with the control for the jack so that the jack cannot be operated if the turntable is clamped. The turntable 4 may be removed from the crosstable, which slides across a saddle 2 movable along the machine-bed 1." |
