220 . The coal will be fed through four' ~ gas only one-seventh of the 'Lhe producer is 9 ft. in diameter and 10 ft. in height. It is of the updraft type, designed to handle the lowest grade of lignite, which costs in this section less than $1 per ton at the mine and from $1.70 to $2 per ton de- livered at tidewater. It is expected to use the pea size on the Archer. hoppers on the top of producer for the purpose of getting a uniform dis- tribution of fuel.. Two gas washers \ TAE Marine. REVIEW inghouse inter-pole generator hung from the ceiling and belt-driven from the main engine fly-wheel. This gen- erator is designed to operate through a variation of speed on the engine flywheel from 225 R. P. M. to 150 R. P. M. and maintain 110 volts. In the event the engine is run at a slower speed than 150 R. P. M., the electrical supply for the various motor-driven machines will be furnished by a Nash 12-kilowatt direct-connected distillate BARKENTINE ARCHER'IN Dock at EacLe Harpor, WaSH. will also be installed on the working platform, one being used for auxil- iary and only one being operated at a4 time. 'This gas washer is one of the vital units of the producer installa- tion and has made the producer a suc- cess on the low grade fuels to be used, as the gas washer leaves in the impur- ities allowable by the American Socie- ty of Mechanical Engineers. Storage for coal is provided between the main deck and poop deck from the sides of the producer housing to the sides of the vessel. Fuel will also be carried from the working platform to the top of producer. An additional supply of coal will be stored between decks, over the engine, being sacked and passed forward through the batch just above the lad- der. More coal will be carried on the decks. On this vessel space is very valuable for cargo and it has been im- possible to install bunkers of any size in the available space of the ship. Space of no value for cargo has had to be utilized for storing fuel. The Archer will carry a rather pre- tentious auxiliary equipment includ- ing a 17-kilowatt, 110-volt D. C. West- engine and Sprague generator. A fur- ther auxiliary for supplying illumina- tion for the vessel 'and operating the wireless telegraph set, will be fur- nished by a Brush 5-kilowatt direct- connected set, which is built by the C. A. Strelinger Co. of Detroit. These three generating sets are controlled on panel of the switchboard allowing any two of the generators to be'used -simultaneously and divide in any man- -ner desired among the various cir- cuits. The switchboard consists of six panels of Vermont marble, each Lat. by 3 it, controlling all the va- rious machines and. lighting aboard. Tor operating the pneumatic. re- verse and clutch, the Lunkenheimer whistle and the starting of the main engine, compressed air will be fur- nished by a Blaisdell duplex 4 x 5 self-oiling enclosed compressor, gear driven by Westinghouse motor. The air receivers for the compressor will be two Blaisdell cylindrical tanks 30 in. in diameter by 8 ft. in length de- signed for pressure of 150 lbs. By ineans of a Sundh pressure regulator and motor starter on an_ individual panel, the air pressure will be main- circuits June, 191] tained at the desired point. This pres. svre regulator is designed to start the motor when the air pressure falls to a determined point and stop the motor when the pressure has reached the de- sired amount, thus making the air pressure automatic. To handle bilge water and also for supplying water through sea connec- tion for washing decks and for fire protection, a' motor-driven bilge pump will also be installed. A direct con- nected. centrifugal pump operated by a 2-H Fic G. Es. motor. wills farnien water supply for the producer gas washer, etc., and can also be used for auxiliary engine circulation in case of accident to the main engine circu- lating pump. The water supply will be brought in.through a 4-in. Liberty twin strainer. In the engine room a work bench will be provided with all necessary tools which the space will afford for making repairs. There will also be a locker for material and spare parts. A full supply of spare parts for all the machines will be carried, enabling re- pairs to be made to "any 'ordinary breakage without delay. The engine room will be ventilated by natural draft ventilators and both engine room and producer gas room will be further ventilated by an exhaust fan in each. To facilitate loading and discharging at Roche: Harbor and San Francisco respectively, a barrel elevator will be installed, with a capacity of 800 bar- rels an hour. This contrivance will likely be furnished by the Meese & Gottfried Co., of Seattle and San. Francisco, It is further planned oper- ating a conveyor on the dock at Roche Harbor to receive the barrels as they reach tidewater and carry them to a storage warehouse about 500 ft. dis- tant. When loading the vessel, the operation will be reversed, the barrels placed on the conveyor and discharged into the vessel's hold about 500 ft. distant. Extensive cleaning is necessary af- ter each voyage, as the vessel's holds and decks are littered with lime dust and parts of broken barrels. Jn order to properly clean the ship, an 8-in. pipe line will be run the length of the vessel in the main hold, connect- ed with an exhaust fan, discharging over the side of the ship into the water. At convenient points slide Openings will be arranged into which ait 8-inch flexible pipe may be inserted, having a nozzle at the free end, with. which the interior of the ship will be thoroughly flushed after each cargo is discharged.
