: | ' IM CN ee eT HE Edward Valve & Mfg. Co., Chicago, is distributing a 94-page booklet devoted to valves made of semisteel, bronze, steel and monel | metal. The steel employed is said to have an elastic limit of 37,340 pounds. per square inch, and a tensile strength of 72,650 pounds per square inch. Monel metal is especially recommended for valve trimmings in use under severe con- ditions. This material is said to: be tough and ductile, to resist corrosion, and to maintain its strength under high temperatures. Monel metal is approxi- mately 67 per cent nickel, 28 per cent copper, and 5 per cent other metals, and contains no zinc, tin or antimony. In the body of the catalog considerable space is devoted to descriptions of the valves, particularly to interesting fea- tures in their design patented by the Edward company, and to price lists and “specification tables. Taking Care of Boats The Murphy Varnish Co., Newark, N. J., is distributing an attractive booklet on the proper care of boats. The booklet contains a number of. handsome drawings, printed in two and three colors. In addition, a num- ber of interesting points regarding the correct use of varnish in preserv- ing boats are given. Soot Blowers “How Some Ship Owners Have In- creased Their Profits” is the title of a new bulletin issued by the Diamond Power Specialty Co., Detroit, to de- scribe the features of its soot blowers. Ship boilers equipped with mechanical blowers may be blown regularly at intervals of from 6 to 12 hours, de- pending upon the quality of the fuel, without waiting for an _ occasional opportunity to open the breeching doors and bank fires. These blowers, which may be applied to all types of marine boilers, are said to effect a fuel saving of about 5. per cent. Boiler efficiencies are thereby in- creased from 4 to 8 per cent. An interesting portion of the pamphlet describes graphically the heat-resist- ing characteristics of soot, showing the percentage of fuel loss for depos- its of various thickness. It is stated that soot is five times as effective a heat insulator as asbestos. Numer- Al Pertinent Suggestions and Personal Gossip ous illustrations show vessels. that have been equipped with the Diamond company’s blowers, as well as cross sections of boilers to indicate the method of installing the blowers. An effective portion of the bulletin shows a method of figuring the saving of fuel resulting from the proper clean- ing of boilers. Elected President John D.

Expect Big Season Officials of the Cleveland & Buffalo Transit Co., Cleveland, predict that the coming season will surpass all ‘others in the volume of passenger and freight traffic between Cleveland and Buffalo. The first few weeks of business this season furnish conserva-. tive grounds for this prediction, as the early traffic has been unusually heavy. Three steamers, the SEEAND- BEE, the City oF EnRrtr, and the Ciry oF BUFFALO, are now plying between these Lake Erie ports. Piston Rod Packing The C. Lee Cook Mfg. Co., Louis- ville, Ky., recently issued a 24-page bulletin. devoted to metallic \ piston | rod packing. How the packing is maintained in a tight position on the rod by springs and followers is shown clearly in diagrammatic views of the arrangement in the stuffing boxes of the various packing rings and acces- sories of both the single and double type. Split metallic piston rod pack- ing for use in steam engines, in refrigerating machinery is also de- scribed and illustrated. In the dou- ble type packing for corliss engines a tap is entered into the stuffing box by means of a pipe, on which a globe valve is placed, and which is led off to the receiver. The receiver pressure thus introduced between the two sets of babbitt rings is said to act as a steam seal, balancing the atmospheric pressure. This method is said to also act as a drain for condensation. <A number of large vessels in the United States navy are completely equipped with the company’s packing. Sp sue on
