The Weil-McLain ROUND TYPE BOILER with its COR RUGATED FUEL-SAVING HEATING SURFACES and its long "back and forth" fire travel embraces the newest and best conceptions of heating engineers. Other points of merit in the Weil-McLain Round Type Boiler are: fire-pot and crown sheet cast separately to permit easier handling; large fire door; handy front clean-out doors in every section and triangular type grates which cut and shake out all ordinary clinkers.

Y. PRODUCTS: Duplex Water Feeders Duplex Switches McDonnell & miller duplex WATER FEEDERS McDonnell & miller duplex switch The McDonnell & Miller Duplex Water Feeder is a simple and positive means of controlling the water line in low-pressure steam boilers, automatically supplying make-up water as necessary, and protecting the boiler against flooding by disposing of any excess condensate that may be returned from the system. It is completely self-contained. Steam and water equalizing connections as well as supply and overflow connections, are all made in the head so that floats and valves may be exposed for .inspection without breaking a single pipe connection. May be applied to all steam heating systems whose pressure does not exceed 15 pounds and are suitable for city water pressures up to 115 pounds. Weight, packed for shipment, 50 pounds. The McDonnell & Miller Duplex Switch is a combination Low Water Cut-off and Pressurestat for oil fired boilers. When the boiler water line falls to the bot tom of the gauge glass the switch cuts out the oil burner motor and cuts it in again when there is at least one inch of water in the glass. The pressurestat may be adjusted for any cut-out pressure from 9 ounces to 10 pounds 6 ounces and the difference be tween cut-out and cut-in pressures may be varied at will from 7 ounces to 5 pounds 6 ounces. The switch movement is-springless being operated on the weight-and-lever prin ciple. It is permanent and accurate in its adjustment and may be easily- adjusted without tools. . The Duplex Switch is easily installed in the gauge column in less than an hour. Weight, packed for shipment, 25 pounds. 383
