A return trap built to solve the flor- ist's steam heating problems has been placed on the market by the Morehead Manufacturing Co. Detroit, Mich. The old system of gravity re- turns by placing the boiler below the ground, or the employment of a pump to return the water to the boiler against the steam pressure, were both expensive and unsatisfactory. The Morehead return trap is a simple, effective and inexpensive device for returning all condensation in steam pipes to the boil- ers regardless of the position of the latter, whether above or below the coils. It performs this function in a positive and thorough manner. Once installed, it requires little or no attention and can be relied upon under all conditions. The trap consists of a cylindrical steel tank receiver of suitable capacity, swung on a brass trunion and actuated by a counter weight. Two smaller counter weights, in turn actuated by the larger, automatically operate a steam admis- sion and an air relief valve. A steam port and two wafer conrKCtions, the latter provided with check valves for maintaining a flow in one direction, completes the list of trap parts. The condensation in the returns is forced into the trap tank by the steam pressure from behind. When the tank has re- ceived a requisite amount of water, it tilts, automatically opening the live steam valve admitting steam at boiler pressure to the tank, thereby equalizing the pressure in the system and permit- ting the contents to flow into the boiler by gravity. All moving and adjustable parts are entirely
