Duplex Boring-Machine.—Fig. 5 shows a machine built by Pedrick & Ayer for boring the two cylinders of a duplex pump at one time. The centers are made a fixed distance apart, to suit the centers of the pump-cylinders. The machine is therefore a special one, designed to be used upon but one size of pump. The platen is fed by a nut and screw driven by a 2½ in. feed-belt. |
