"Vintage Machinery" entry for Frank Pearn & Co., Ltd.
"Machine tools for boring, facing, and milling, having vertically movable headstocks fitted with spindles carrying a faceplate which has an automatically traversed tool-holder, are driven by means of an endless belt without the intervention of toothed gearing, but back gear is provided for use if required. A' speed cone and pulley b, c, Figs. 1 and 2, drive a pulley e by belt d, passing over an idler i mounted on the headstock and a normally fixed pulley k carried by the framing, but adjustably mounted at n to take up stretch in the belt. The pulley e is mounted on a loose sleeve f, and can be bolted at t to a fast collar on the spindle for a direct drive, or can drive through disconnectible back gearing r and change gear v, w, x. The spindle is hollow, and contains a feed-spindle o geared to it at q and to the feed-screw p. The work is carried on a compound table on the bed."
