WORLDS FAIR NOTES.
 An Interesting Exhibition Conducted
 in Charge of New Haven Man.
 MT. J. Betts Smith, son of Dr. J. Fl. Smith the dentist. is in charge of a notable exhibit at the worlds fair. We copy . portion of an article descriptive of this ex- hfbit from the Electrical Engineer.
 The Thomson Welding company of Boston, are making large exhibit in the electricity building. Eleven pieces of ap- psratus, including two complete plants and various miscellaneous mechanism, form the most striking and the largest part of the display. Y @
 On the principle that the excellence of a proosss is best shown by specimens of Rnished work, the company devote consider able space to boards covered with samples loaned by various manufacturers of work done in their several factories. A brief reference to these will be interesting, as showing the wide range of mechanical operations to which electrical welding is applicable. From the F. Wesel Manufac- turing company of New York, are printers chases with right angle welds at the corners, accurate to :0O2 inch; there are specimens of copper wire welding from the Benedict & Burnham Manufacturing company of Wa terbury, Conn.,, and the Tamarack Osceola Copper Manufacturing company of Dollar Bay, Mich, the latter company showing e three-eighth inch copper bar with eight welds, and what was an exactly similar bar reduced to No. IA wire, welds and all. The Parry Manufacturing company of Indian apolis, contribute 8 number of tires and hub bands, and from the -Gendron Iron Wheel company of Toledo, are shown all forms of tires, channel, crescent, oval, half oval and flat for bicycles, baby car risees, etc. The Electric Pipe Bending company of Harrison, N. J., show all sorts of pipe work for ice making and refriger ating machines; return bends with the weld in the center, and also welded to steel or wrought iron fsnges and female joints; pipe welded to square bends and to forged steel couplings, and 6 number of specimens showing the great strength of the welds under severe tests. These pieces have been bent and twisted out of all semblance to their original forms, and subjected to heavy strains, and in all cases where break has occurred 1t has been outside of the weld. Studebaker
  and carriage axles from three fourths of an inch round to one and one half inches square, tires from one and one eighth to two and one-half iRches, and various sizes of hub bands, while the Kentucky Wagon Manufacturing company of Louisville, Ky, show sections of welded tires as large as three and three-fourth inches, and Haydock Brothers of St. Louis, Mo-, exhibit axles of all sizes and shapes.
 In many cases the current has been used to heat the work for forging as well as in 9he weld. Shuttler & Hotz of Chicago have complete set of all the sizes of hub bands used, and the New York Fifth Wheel company of Brooklyn show speci- mems of welded channel iron in circular form for their anti-friction wheel. The Sheldon Axle company of Wilkesbarre, Pa., show two axles bent double at the weld. From the General Electric company are shown various sizes and sections of welded copper wire for srmatures and fields. E. 0. Atkins & Co.,, of Indianapo- lis show welded saw blades and the Rich mond Cedar Works show specimens of welded wire bands for pails and tubs. Here are also steel rods from the Carnegie Steel company of Beaver Falls, Pa and high carbon steel wire from the Hazard Manufacturing company of Wilkesbarre, Pa., galvanized and plain wire from Washburn & Moen of Worcester, Mass, and telegraph wire and steel cable from the Trenton Iron company, all weld, ed in various ways and for various pur' poses, and also specimens of carriage hard ware from the Sidney Pole and Shaft com pany of Sidney, O., the Cortland Forging company of Cortland, N. Y, and M. Seward & Son, New Haven, Conn. One board contains some 2} inch steel bars welded and tested on the testing machine at the United States Arsenal st Watertown, Macs. These all broke outside of the weld at strains of 3s7, ,O00, 39s, 300 and 390, ,50C pounds, respectively. Miscellaneous specimens of welded work are steel wire cables with hemp center brass welded to iron. pieces of aluminium steel band saws, high grade steel edges welded to iron or low carbon steel tools in halves welded together, tires welded l and spokes electrically upset on the upset l ting machine, and pipe coils, round, flat ! oval and zigzag.
 l An important feature of the display ii ! the collection of specimens from the John ! son company of Johnstown, Pa. Among ! these are combination splice bars to faster ! two rails of different sections, and also s ! section through an electric rsil in which | Guo ClAlI lS Wolucu ulIocbly tO tAo Ihil l1 | self In this the chair is rolled with 6
 bead at the top and the rail with cup al ! the bottom of the web. The one fits into \ the other and the weld Is then~made. A three way crossing is shown among | these specimens having six different l welds, not one of which is less than twelve l square inches in cross section, and also a
 railroad crossing of rolled steel welded to. gether in one solid piece. Another inter esting exhibit from the same company ie l the largest electric weld ever made, having
 8 section of forty-eight square inches.
 The American Projectile company of Lynn, Mass show number of shells with highly tempered points welded on electrl-
 cally. Some of these have been repeated ly fired through armor-plate. The Con | solidated Storage Battery company have | samples of clements in which the plates ! are electrically welded to the heads
 MT. Smith has been with this company
 for over three years, and installed several of the plants mentioned in the above. He is meeting many old friends at the fair and l renewing pleasant acquaintances.
