THE GENERAL ELECTRIC CO.'S EXHIBIT AT ATLANTA.

 

THE central space in Electricity Building at the late Atlanta Exposition was occupied by the compact and well-arranged exhibit of the General Electric Company, illustrating the latest developments in the fields of electric lighting, railway and power.

The exhibit which is illustrated in the accompanying engraving, was erected on a raised platform surrounded by a cornice supported on columns of white enameled iron. The cornice was decorated with a row of miniature purple lamps breaking into groups of amber lights over the caps of the posts. The side of the cornice facing the exhibit was ornamented with a line of frosted lamps.

The railing was an exhibit in itself, made of lengths of one inch brush-holder cable, stretched between standard insulated railway turnbuckles. It was supported on posts capped with General Electric insulators. At the ends of the platform the place of the cables was taken by nickel-plated trolley wires supported on high tension porcelain insulators of the double petticoat pattern, similar to those used for the Sacramento Folsom plant. The roof of the office, which stood in the center of the space, was decorated with a large model of an Edison lamp socket, three feet high. In the construction of which not less than 700 standard sockets were used.

The office stood under an arch—one of the most interesting features of the exhibit. It was a model of the upper field of one of the large 800 k. w. monocyclic generators now running in the station of the Edison Illuminating Company. St. Louis. Mo. The model is full size, 21 feet in diameter. These generators are the largest that have ever been constructed and operated. As erected here, the armature could be set upon the floor and just fit the field frame in its present position. The supports for this model were two large pyramids, the four sides of which formed display boards on which were artistically arranged fine selections of the many lines of railway, power and lighting supplies made by the company.

While the visitor was impressed with the model of the great monocyclic generator field, an opportunity was also afforded him in viewing the monocyclic system itself in actual operation. A monocyclic generator of 250 k. w. capacity ran day and night in Machinery Hall and supplied current for the illumination of a large portion of the halls and buildings, as well as for the operation of 30 and 50 h. p. induction motors. The visitor was thus enabled to judge of the flexibility of the system from personal observation.

One corner of the exhibition space was occupied by a 30 horse power three-phase induction motor driven by current from the monocyclic generator just mentioned. The motor is started by the closing of a switch and comes to full speed quickly. This motor drove a 20-kilowatt, 125-volt, four-pole, slow-speed generator, furnishing current to illuminate two signs, each forty feet long, conspicuously hung below the balconies opposite each end of the exhibit. The name of the General Electric Company was spelled in eight-candle-power lamps and stood out prominently in neat white script against a black ground.

A full set of the latest type, plain and ornamental, arc lamps for incandescent circuits were shown hanging from a stand of wrought iron scroll work. Several arc lamps intended for use, ten in series, on 500-volt railway circuits, were also shown. This display
