MARINE TYPE 12 and 16 INCH FANS NOW IN USE ON THE S. S. ‘SAMERICA”’ Diehl Marine Type Fans as now used on the S. S. ‘“‘America’”’ are especially designed for service on shipboard or where subjected to sea air. Graceful and well proportioned they harmonize readily in most any surroundings and deliver a large volume of air with unusual quietness and absence of vibration. Particularly note- worthy are the following features: (a) Blades of solid brass or monel metal. (b) Guards plated with brass and japanned. (c) Motors entirely closed and dust-proof. (d) Windings specially insulated and impregnated to re- sist action of sea air. (e) Rheostat, small parts and fittings of non-corrodible and non-absorbent materials. (f) Special insulation, to guard against action of sea air and to resist moisture of tropical climates. THE NEW GYROCONE CEILING FAN A standard time tested item of the Diehl line now presented for marine service. Especially adapted for salons, reception rooms, dining rooms, ball rooms, etc., and wherever complete air distribution without direct draft is essential. Scarcely larger than a bracket type fan the Gyro- cone completely and more efficiently performs the duty heretofore assigned to large blade ceiling fans. Mounted in a ball bearing pivoted cradle, a sturdily built twelve inch, four blade fan gyrates through full 360 degrees at an angle of 27 degrees from vertical providing a total sweep of air of 54 degrees. Eight complete revolutions per minute at high speed cir- culate air over a greater area than is possible with other types of fans. Operating parts are enclosed in dust-proof iron housings and all moving parts are ball bearing equipped. Lubrication reservoirs are sufficient to insure continuous operation, under nor- mal conditions, over a period of two years. A sturdy wire mesh guard with openings not larger than %-in. completely surrounds the blades.
