1900 MARINE REVIEW. : 19 STILWELL'S CAST IRON HEATER. The Stilwell-Bierce & Smith-Vaile Co. of Dayton, O., is placing on the market a new cast iron feed water heater. The cast iron heater which this company makes (the shell be- ing made of boiler steel) is de- signed particularly for use on water which contains acids, salt or 'other material that pits or eats out wrought iron. The style of the heater is well portrayed in the ac- companying illustrations--a gen- eral view of the heater and a sec- tional view. Referring to the receiving chamber and oil separator it will be noted that the incoming ex- 'haust steam impinges upon the conical deflecting plate, which is provided with grooves and which separates the cylinder oil, carry- ing it to sides and bottom of the chamber to the opening marked "oil discharge." This deflecting plate also carries the steam down- ward, as indicated by the arrows, to the two rectangular openings through which the steam passes into the heating chamber. The construction of the receiving chamber is such as to prevent shock and breathing of the heater, which would result from admitting the exhaust from high pressure engines direct into the heating chamber. Steam is admitted into the heating chamber from the receiving cham- ber through two rectangular openings, which extend nearly across the plate that separates the two chambers. Two long continuous streams of steam are thus directed into the body of water which is falling constantly in thin sheets over the edges of the oval-shaped pans, thus presenting the best possible conditions for transferring the heat in the steam to the water. The uncondensed steam escapes freely from the top of the heater, and the Suwausr (egy RECEWING (CHAMBER O14 OICHARGE REOWULATING FLOAT FuUTERING CiapdekA | fl auth fibeong WATER SECTIONAL VIEW OF IMPROVED CAST IRON HEATER. construction is such as to prevent carrying water out with the escape steam. The lower portion of this heating chamber is a reservoir of large capacity filled with hot water. It also serves as a settling chamber and a receptacle for the condensation returned from radiators or heating coils that may be in use. This chamber is provided with two floats--one for regulating the inflow of feed water and one for regulating the overflow, thus affording a double safeguard against flooding the heater. The filter- ing chamber filters upward, thereby retaining any soft material at the bottom of the heater where it can be blown off. There is the special advantage of quick and easy access through large doors and handholes to every part of the heater. The Nickel Plate road offers special low rate of one cent a mile traveled to Findlay, O., account annual encampment of G. A. .R., depart- ment of Ohio. Tickets available May 7, 8 and 9, good returning until May 11 inclusive. Inquire of agents or address C. A. Asterlin, T. P. A.. Ft. Wayne, Ind. 56, May 9. AMONG MANUFACTURERS. _ New York offices of the Berlin Iron Bridge Co., East Berlin, Conn., which will continue to be in charge of Mr. Seymour N. Robinson, will be removed to the St. Paul building, No. 220 Broadway. The Brown Hoisting & Conveying Machine Co. of Cleveland, is fill- ing an order for coal handling machinery for the Egyptian state railway. The plant is designed to handle 300 tons per day and will be installed at Alexandria at a cost of $300,000. The Marine Iron Works of Chicago has obtained the sole control on the lakes and western waters of the Watson radial water tube boiler for aterm of years. Arrangements are being made at the Chicago works to put this boiler on the market in sizes from ten to 150 horse power. 'The entire equipment of pumps onthe Savoie and her sister-ship La Lorraine of ithe French line are of the Blake type, made by the George F. Blake Mfg. Co. of New York. The Review in saying recently that engines of the Savoie are of 12,000 horse power told only half the truth. There are two of them of 12,000 horse power each. The Bullock Electric Mfg. Co. of Cincinnati has issued an instructive little catalogue devoted to marine lighting and power sets. It is well known that the requirements of the marine service are difficult to fill. Weight, space and durability are the three essentials which the Bullock company have sought to introduce in their marine sets and their success in combining them will delight marine architects and ship builders. The Columbus Chain Co., Columbus, O., has been incorporated with a capital stock of $100,000 and has elected the following officers: Clar- ence H. Hanna, president; Charles M. Wambaugh, vice-president and treasurer; S. A. Webb, secretary, and Daniel Carroll, superintendent. The company will manufacture a general line of chain goods which will include chains of any given dimensions and pitch for the transmission of power, under the patents granted M'r. Carroll by the United States, England and Germany. The latest improved machinery will be purchased. : The retirement is announced of Mr. J. D. Clary, for many years iden- tified with the Bourne-Fuller Co. of Cleveland, dealers in iron and steel. The present organization of the Bourne-Fuller Co., in view of this change and the election of W. F. Bonnell as manager, announced last week, is as follows: President, B. F. Bourne; vice-president, H. A. Fuller; sec- retary, L.:H. Elliott; manager, W. F. Bonnell; treasurer, H. C. Bourne. These, with Mr. E. H. Bourne, president of the Bourne & Knowles Mfg. Co. and cashier of the Union National Bank of Cleveland, comprise the board of directors. The Standard Chain Co., the recently organized consolidation of the majority of the chain plants of the country, purchased last week the chain plant of the American Steel & Wire Co. at the latter's HP Nail Works, Cleveland. The machinery in this plant will be removed to Rankin, Pa., where the Standard Chain Co. is erecting a building 500 feet long and 100 feet wide. In addition the machinery in the Baker plant, together with the Garland plant which adjoins the new building, will have a capacity for turning out 25 per cent of the chain manufactured in the country. The report that all the plants taken into the consolidation would be concentrated in the Pittsburg district is denied. The only con- centration that will take place is that mentioned above, the remaining plants being operated as heretofore. The offices of the Standard Chain Co. are located in the First National Bank Building, Pittsburg--lIron Trade Review. The American Insulating Material Manufacturing Co., Nos. 213 and 215 Third street, St. Louis, has just issued a little pamphlet, beautifully illustrated, giving a description of granite rock wool and its products. It would be well for everybody who is interested in boiler and pipe cover- ing to write for one of these pamphlets. The coverings are produced from pure rock fibre and contain no cork, sponge, hair or other animal or vegetable matter. (Granite rock wool is a perfect sponge material and no chemical or other change takes place in it. It is said to be practically indestructible and is at least worthy of investigation by steam users. It is made by converting granite rock to a fibrous condition. In appearance it * eonsists-of a mass of very fine fibres interlacing each other in every direc- tion, forming an innumerable number of minute air cells. The St. Louis company claims that it is the only manufactured wool that is free from sulphur and acids and perfectly non-corrosive. ACTIVITY IN DELAWARE RIVER SHIP YARDS. From Camden, N. J., the report comes that the ship yards along the river front are unusually busy. 'At Dialogue's ship yard 300 men are employed. 'The firm is completing a new steel hull tugboat for the Pro- pellor Tugboat Co. of Savannah, Ga. She will be 128 feet over all, 25 feet beam and 14 feet deep. The firm is also building a steel tugboat for the Tice Towing line of New York. This boat will be 135 feet over all, 25 feet beam and 15 feet deep. New boilers and machinery are also being placed in a wooden tugboat for John Scully of South Amboy, N. J. The firm is also doing considerable boiler and machine work for Mexican concerns. At the ship yards at Cooper's point, the various firms have a large amount of repair work on hand. The Mills yard is particularly active. Mr. Mills is building a new dredge and several scows for his own fleet. This firm has the contract for overhauling the entire fleet of col- licrs, scows and sea tugs of the Philadelphia & Reading railway. S. W. Tilton & Sons are building a lighter for Peoples Bros. of Philadelphia. Rilatt & Barrett have been overhauling the tugs Ellen McAvoy, Isabel and Harry Schaubel, Jr., the schooners Jane Middleton and Rebecca Sheppard and a number of barges. Peter Hagan & Sons are building fcur barges for their own fleet. The Prindle Engineering Co. of Camden, N. J., is the lowest bidder at $37,500 for the construction of a pumping plant at dry dock No. 1, New York navy yard. The keel of the new Steamer Mainlander, which is to be operated by Cook & Co. on the Vancouver line, has been laid at the ship yards of Crawford & Reid, Tacoma, Wash. She will be launched on July 4. She will be a Tacoma-built boat from stem to stern and will be the largest steamer ever turned out by Crawford & Reid. Work will be rushed upon her to make room for other boats that are to be built at the same yards.
