Besides, the work-holding de- vices are hydraulically clamped. Other features the machine, designated type include improved hob spindle mounting, automatic hob clearance, new operating speeds, ease and con- venience over older types B-C hobbers, simplicity design, result- ing rigidity and strength, hardened steel ways, and automatic pressure lubrication throughout, including the compartments which enclose change gears.

Electrically Controlled Plain Grinders Representing complete departure from previous grinding ma- chine design, the new series plain grinding machines now being mar- keted Brown Sharpe Mfg. Co. Providence, are operated entirely electrical control. They are com- pact, powerful manufacturing units, self-contained, and are de- signed for the cylindrical grinding medium-large parts production basis. All operating functions all major units the machines are gov- erned the simple manipulation various selector switches and control knobs, grouped the front within easy reach the operator.

When the work size, the cross feed automatically disengaged, and rotation the handwheel the starting posi- tion withdraws the wheel and stops the headstock, table and coolant pump. - Two control knobs provide for man- ual operation. Turning the table knob starts and stops the table; and press- ing down the knob will cause the table stop the end its travel. The headstock knob starts and stops the headstock and coolant pump together, and turning selector switch, this knob can also made start and stop the table movement. Whenever desired inspect the work, de- pressing the headstock knob will stop the flow coolant without affecting the headstock rotation, and the same control can used job the head- stock loading work.
