The Atlantic “geared-head” miller was manufactured by the Atlantic Machinery Corporation of 149 Broadway, New York. in, so far as can be ascertained, the 1930s and 1940s. The 1 hp drive motor was held within the cast iron base – which also held the standard-fit coolant pump and tank – and drove up via twin V belts to a 6-speed gearbox, contained with the body of the miller, and holding gears which were all forged and hardened; whilst the standard machine was dispatched with a bottom speed of 150 rpm and a top of 675 rpm, alternative ranges were available to special order including 200 to 900 rpm and 3000 to 1350 rpm.
