HE Schutte & Koerting Co., Philadelphia, has developed an apparatus for producing pure water for drinking -and_ cooking purposes on- lake vessels. This system consists of an evaporating and condensing apparatus, steam being taken either directly from the boilers, or by bleeding the low-pressure receiver in reciprocating engines, or by taking - auxiliary exhaust steam. The steam is passed through the coils of an evapo- rator. The drain from the evaporator coils is taken to the hot well and used for boiler feed while the vapor is carried through the vapor pipe to a dis- tilling condenser. Here the vapor is condensed and cooled, the condensate then passing to the filter and aerator and from there draining to the fresh water tank. An evaporator feed water heater, designed to increase the economy of operation, may be placed in the vapor, line. The: company states that two pumps should be used in connection with this plant. One pump would take the lake water and pass it through the distilling condenser in order to condense and cool the pure water. The raw water would then bé discharged overboard. The ship’s injection pump could be used in place of this pump. The _ second pump would take the water direct from the lake or from the overboard dis- charge from the condenser, and feed this water to the evaporator. The im- pure water left in the evaporator would be discharged overboard while that por- tion of it evaporated was passed’ to the distilling condenser. ‘The Schutte & Koerting Co. has made a large number of installations on sea- going vessels. The arrangement of these installatioris is substantially the same as that outlined. Experts of the company point out that while this ar- rangement is necessary where sea water is used, it is even more advantageous when using comparatively pure lake water, as the efficiency of operation will be increased and the necessary number of cleanings reduced. A recent bulletin of the company de- scribes and illustrates in detail the de- sign and operation of the company’s evaporating and distilling plant.

Steel Equipment A catalog describing a wide variety of steel equipment for use on ships, was issued recently by the Bernstein Mfg. Co., Philadelphia. The company manufactures many different types of berths. One type is adapted for shore and harbor work, or for immigration and detention stations. Stanchions of 2-inch steel tubing are fitted with deck flanges and with adjustable flanges at the top. The berth frame and lee rail are steel tubing, chilled- jointed construction. The berths hinge on flat-head steel pins chilled onto the frame which rests in the brackets on the stanchions. The berths are sup- ported at each end by a heavy chain, which is riveted to the frame and at- taches to hook brackets on _ stanch- ions. The berth is finished in alu- minum bronze. Among the _ other equipment described are folding and stationary steerage and crew, and stateroom berths; staterooms and dou- ble deck beds, steel lockers, chiffon- iers, tables, chairs and cabinets. Develops New Engines During the past year, the New London Ship & Engine Co., Groton, Conn., has deyeloped two new types of engines. One is a 4-cycle direct reversing type, of which the first pair to be .completed were 8-cylinder, 600-horsepower units. The other is a 4-cycle, double-acting type, of which a single-cylinder, 200- horsepower experimental unit of marine type has been run in the shop for the past nine months. This type is to be built in 4 and 6-cylinder models, and up to 500-horsepower to the cylinder. All engines which this company is now building are of the 4-cycle type. The plant at Groton has been en- larged greatly, but even with the in- creased capacity it is running 24 hours a day in all departments, and the com- pany is booked to capacity for all of 1917. Efforts are being made to arrange for additional capacity to handle addi- tional orders for engines for both naval and commercial vessels. Among the many installations made by the New London company during 118 Ll mice Z a ZA SSS 1916, exclusive of those used for power plants in submarines for the United States and foreign governments, the fol- lowing may serve to show the kind of service for which these engines are em- ployed: W. C. T. U., built at Friendship, Me., is a 101x 16% x 7- foot, 65-gross ton fishing schooner; 120-horsepower, 4- ‘cycle, reversing gear type. Powe tt, built at Westlake, La., 105x 27x 9- foot, cargo schooner; two 60-horsepower, 4-cycle, reversing gear type. Lucia, built at Gloucester, Mass., 9914 x 26 x 7¥Y%4-foot, fishing schooner, 95 gross tons, 43 net tons; 120-horsepower, 4-cycle, reversing gear type. Bettina, built at Gloucester, Mass., 108% x 22 x 8-foot, fishing schooner; 120- horsepower, 4- cycle, reversing gear type. AsPINET, built at ‘Chelsea, Mass., 102-foot fish- ing schooner, 126 gross tons, 83 net tons; 120- horsepower, 4-cycle, reversing gear type. Atycon, built at Guadeloupe, F. W. I., pas- senger and freight vessel; 120-horsepower, 4- cycle, reversing gear type Netseco JI, built at Boothbay, Me., 123x 26%4-foot ferry, 140 gross tons; 240-horsepower, 8-cylinder, 4-cycle, reversing gear type. Espana, built at San Juan, P. R., 150x25.x 12-foot cargo. vessel, 400 gross tons; 240-horse- power, 4-cylinder, 4- ‘cycle, reversing gear type. Two water and supply boats for the Panama canal, built on the isthmus, 85x 20x7 feet, 185 gross tons, each equipped with 120- “horsepower, 4-cycle, reversing gear type. Catalog on Injectors A new catalog has just been issued by the Penberthy Injector Co., Detroit, Mich. It contains a large amount of data not only on injectors, but in connection with all jet apparatus and shows a complete line of brass’ spe- cialties pertaining to the steam, plumb- ing and automobile accessory trades. A copy will be sent on application. Oil Burning System A 56-page bulletin, recently issued by the White Fuel Oil Engineering Corporation, New York, contains a comprehensive description Of fuel oil apparatus and its adaptability for use in the marine field. A number of pho- tographs of ships equipped with the company’s fuel oil burning system, are reproduced. The principle of con- struction of the burner is simple. The burner is designed to atomize the oil, previously heated to the point of fluidity, by driving it along grooves on a conical surface from which it is discharged with considerable velocity upon a finer angled cone, issuing through a nozzle or tip as a finely divided spray at a pressure of 60 pounds. The company has developed both duplex and simplex unit sys- tems. These equipments are made in sizes from 200 to 2,000 horsepower.
