-- MARINE REVIEW. Samah : A New Injector. | Bee _ There is illustrated herewith a new injector for which the makers claim most remarkable and wonderful results. It is called the Inter- national, and one claim of merit for itis that the current of water to the boiler is established against atmospheric pressure instead of against direct boiler pressure as heretofore, This is accomplished by the com- bination of the overflow valve K and pressure valve L. When the injector » starts, the steam passing through the steam jet F and suction jet G passes down through the overflow. chamber, forcing the valves K and L : away from their seats and opening the passageway through the overflow for the escape of steam, which by its pressure against the valve H holds | both valves away from their seats. A vacuum being created between the jets F and G, the water is lifted, and passing through the suction jet G and combining and delivery jet H on its way to the boiler, passes down through the secondary overflow, and out through the passageways be- tween the pressure valve L, and pressure valve collar M. As the pressure © increases in the delivery chamber around the delivery jet H, the valve L, is gradually forced to its seat against the collar M, but does not finally close until the current to the boiler is firmly established. The valve K in the meantime is closed by the vacuum in the overflow chamber. By a new construction of the parts in the steam chamber, the same valve han- dle A opens the valve admitting steam to the injector, and at the same time regulates the amount of water supply, therefore no valveis required ~ in the suction pipe, nor is one necessary in the steam pipe, except as a convenience should it be desired to remove the injector at any time while carrying steam on the boiler. 7 Another new feature is the fact that the combination and delivery jet H has no spill holes, and will therefore outwear three of any other make. The makers claim for this injector that it will start at 13 to 15 pounds steam pressure and work from that point up to 250 pounds pressure, giv- ing it a range 100 pounds greater than any other automatic injector. It is automatic and restarting at any and -all pressures. It lifts the water vertically 20 to 22 feet, and handles a hot water supply of 135 degrees at 65 to 80 pounds of steam; 125 degrees at 125 pounds steam. By deliver- ing the minimum capacity it will put water into the boiler at 200 degrees at 80 pounds steam, and 260 degreee at 150 to 200 pounds of steam, the water being taken from a 4-foot lift at 74 degrees. One of the most re- markable features about this injector is its grading capacity. The best injectors heretofore manufactured have a grading capacity of only 40 to 50 per cent., while the minimum capacity of the International is 6624 per cent. less than the maximum capacity of the same size. The parts are made interchangeable, and are all easily accessible for cleaning, und the _ injector is fully guaranteed. It is manufactured by the World Specialty Company of Detroit, Mich. Descriptive circulars and price list will be sent on application, : Trade Notes. A wooden tug 90 feet long is being built by Messrs. Hill of Fish Creek, Wis. The Buffalo Forge Company will equip the steamer S. S. Curry with their system of blowers producing forced draft. F. W. Wheeler & Co. of West Bay City, Mich., will build for Henry Corgan of Eagle Harbor, Mich., a wooden tug of 60 feet keel, 16 feet beam and 8 feet hold. A new boiler of the Scotch type, 12 by 14 feet, has been fitted to the Anchor Line steamer Delaware by the Lake Erie Boiler Works of Buffalo. The Trout works of the same place is replacing the high pressure en- gines of the steamer Birckhead with a fore-and-aft compound. The Lawley Company of Boston recently secured an order for a steam yacht of 100 feet load water line, and to develop a speed of 14 knots, The owner is.as yet unknown but is thought to be Dr. W. D. Hopkins of Philadelphia, who formerly owned the Gloriana and Cinderella. _ Kelly, Spear & Co., builders of Bath, Me., Have closed a contract to build four barges, 175 feet long and of about 900 tons each. The firm for which the boats are to be built have contracted with other builders for ing a bowl suspended upon gimbals and containing mercury, a float five more hulls, and the Bath Iron Works will construct machinery forthe nine boats. ~. Seae ck Mer omerne Sai 3s Vike twee ad A company to be known as the Racine Yacht and Boat Works has" been organized at Racine, Wis., to build boats of all kinds, especially row boats, gas and electric launches and steam and sail yachts: Thecon- cern is already prepdred'to make estimates and submit designs for any-'-. thing in the boat line. Fred W. Martin is associated with the company: as designer. He designed the sail yacht Valient, which was built for Mr. - Berriman of Chicago, and also. superintended her constructions The ~ company will shortly have prepared a valuable catalogue, and-Geo\'D.. Fellows, one of 'the officers, announces that a copy of it may be 'had' by" sending 10 cents to his: address, to cover cost of mailing. ~~~ Illustrated Patent Record. : 'LATEST PATENT OFFICE REPORTS. ~~ 'SELECTED ABSTRACTS OF SPECIFICATIONS OF A MARINE NATURE--FROM™ 11,475.
