The Picture shows the Interchangeability of Air and Electric Motors. “TURBINAIR” AND ELECTRIC DRIVEN IRONCLAD Machines have proved their effectiveness under a wide range of colliery conditions—from anthracite in South Wales, through the Midlands and the North of England, to Scotland. They have shown themselves peculiarly adapted to the natural conditions found in British collieries on account of their safety, compactness, cutting capacity and ease of handling. They are also gaining friends daily with owners and managers on account of their low power consumption per ton, the saving in timber their use entails, and their low maintenance expense. “ASK THE MAN WHO HAS ONE.” SULLIVAN MACHINERY CO., (Established 1850), SALISBURY HOUSE, LONDON, E.C.
