Description: |
| "Divided out of GB-966,736. A horizontal boring &c. machine comprises a turntable 3, and studs 6 with their heads 7 in one or more T-slots 4 in the turntable for clamping it to a cross-table &c. 2. The screwthreaded studs may be rotated in fixed nuts to effect clamping, or (as shown) they may be keyed at 13 to the cross-table 2 and the nuts 10 rotated by levers 11 linked in pairs, Fig. 2 (not shown), and operated by pneumatic or hydraulic cylinders. Adjustable stops limit movement of the levers, the operating mechanism of which may operate an electrical limit switch in the control circuit of a table-lifting jack, as described in Specification 966,736, so that the jack cannot be operated if the table is clamped. The cross-table 2 is mounted on a saddle 1, and the studs are positioned through an opening in the top of the turntable which is then closed by a plug." |
