32 MARINE REVIEW AND MARINE RECORD. TRADE NOTES. The Joseph Dixon Crucible Co., Jersey City, N. J., issue a great abundance of reading matter, all of which, too, is very well done. 'The latest is a little folder devoted to Dixon's silica- graphite paint for protection of heated surfaces. The cover is illustrated with a photo of the Fall River steamer Priscilla, which is painted with silica-graphite paint. This paint is warranted to stand severe conditions for a great length of time. Knecht Bros. Co., Cincinnati, O., say that no one takes a risk when he buys the Knecht sensitive friction drill, as all the com- pany's machines are guaranteed. "For the manipulation of a variety of work," they say, "the sensitive drill press, drilling accu- rately and rapidly, has no equal. For tool room, model shop, instrument makers, manufacturing jewelers, electricians and in- ventors it is indisputably a necessity and labor saver." The Acme White Lead & Color Works of Detroit, Mich., is sending out a dainty portfolio of prominent lake vessels to its patrons. 'The plates are bound in a green cover with cord and so arranged that the additions as they are issued can be fastened within the cover. The plates are well made. The two which have just been issued are those of the steamer Isaac L. Elwood and the North West. Both are printed on yellow tint blocks. The portfolio is issued to advertise the Neptune Marine paint and the New Era marine varnishes which are made by the com- pany. These paints and varnishes are guaranteed as the best to be obtained. The Chicago Pneumatic Tool Co. report a very large increase in sales during the past few weeks and all of their factories are working night-and day in an endeavor to fill orders pouring in. Especially is this the case in the air compressor department. The factory at Franklin, Pa., is being pushed to its utmost capacity. Mr. J. W. Duntley, president, is still continuing his business trip on the European continent and large orders from him are being received by the Chicago office for pneumatic tools, annealing ma- chines, rivet forges, etc. His return is not definitely announced although he will in all probability leave for this country in the very near future. Appointments of local representatives in several lake cities, made recently by the marine department of the Standard Oil Co., which now has headquarters for the lakes in the Perry- Payne building, Cleveland, seem to indicate plans for a very thor- ough organization. At Duluth the marine department will here- after be represented by W. W. Smith, at Milwaukee by W. H. Ballard and at Detroit by E. A. Fitzgerald. These gentlemen will give special attention to the marine trade. Messrs. Smith and Ballard will be located at once in the offices of the Standard Oil Co. at Duluth and Milwaukee, respectively, but Mr. Fitzgerald will not take up the Detroit work until Jan. 1. John F, Allen, No. 370-372 Gerard avenue, New York, has issued a catalogue devoted to Allen pneumatic machine tools. In his preface he addresses the manufacturers of elevated rail- road, bridge and boiler work, saying that his many years of ex- perience in devising and manufacturing the line of machinery de- [ Nov. 20. scribed in the catalogue has enabled him to produce many im- provements that could not suggest themselves to those unfamiliar with the requirements of their lines of work. Continuing he says: "Our pneumatic compression bridge riveters are indis- pensable. Our machines have entirely displaced the portable hydraulic pressure riveters, as the use of compressed air of 60 Ibs. pressure is much more convenient than that of water under a high pressure of 2,500 Ibs., which requires the use of cumbrous iron piping with socket joints. We make the only portable pneu- matic percussion and compression riveters." The catalogue con- tains a complete description of the riveters and is crowded with testimonials. 'The catalogue will be sent to inyone interested upon request. A few of the circulators and steam jets for steam boilers made by H. Bloomsburg & Co. of 700 Dolphin street, Baltimore, Md., were some years ago installed on lake vessels. These de- vices have since made their own way with little or no effort to push the sale of them. The Jenks Ship Building Co. of Port Huron purchased ten of the circulators some time ago and are now ordering four 2%-in. feed and four steam heating circulators, Twenty-three of the circulators have of late been furnished to vessels of the United States lighthouse service. The new Pacific Mail liner, Korea, which recently broke the record for passage of the Pacific, has fourteen sets of the circulators. Capt. H. Blooms- burg, representing the manufacturers, is now making a tour of the lake cities. Both circulator and steam jet, the latter a system of induced draft, are very reasonable in cost. Capt. Bloomsburg's principal object in visiting the lakes was to call upon the Jenks company and to see Chief Engineer Hayes of the Pittsburg Steam- ship Co. (Steel Corporation), who contemplates putting the cir- culators into some of the Steel Corporation vessels to be laid up at Duluth during the coming winter. The Pittsburg Blue Print Co., 1505 Park building, Pittsburg, has issued a catalogue devoted to its patent cylindrical electric copier. The company has already installed over 100 of them in the offices of some of the largest and most conservative concerns in this country. The copier is, of course, entirely independent of the sun. 'The standard upright machine is regarded as the best type for almost all work. It consists of two half-glass cylinders, bent to practically true curves, bound together with brass bands top and bottom, and having wooden strips between the edges df the glasses. A strong canvas cover fits around the glass to hold the tracings and paper in place and insures good contact.' The cylinder rests on a base, which is mounted on wheels and re- volves about the axis of the cylinder. An arc lamp of special de- sign and construction is suspended by chains, which pass over the sheave wheels on the bracket and are attached to a counter- weight on the back of the machine, the lamp being slightly heavier than the counterweight. Another chain connects the counter- weight with the drum of the auto-gear or escdpement mechanism for regulating the speed of the lamp in its descent. In operation the tracing and sensitized paper are placed between the glass and canvas cover, and the lamp passing axially through the cylinder gives uniform exposure to all parts of the print.
