Peirce exhibited at the Chicago Electrical Show

THE CHICAGO ELECTRICAL SHOW OF 1907.

The second annual Chicago Electrical Show, which has been in progress at the Coliseum for two weeks, beginning January 14th, was, without doubt, the most complete, profitable and generally successful electrical trade exposition ever given in this country. It might well be called an educational exposition, as the predominating spirit among the exhibitors seemed to be along the lines of making clear to the public the manifold uses to which electricity can be put and to demonstrate the innumerable advantages in the application of electricity to every-day work in every walk of life.

All kinds of electrical machines, devices and appliances, with kindred apparatus, were exhibited at the show, as a study of the pages in this issue devoted to the show will prove. Some of the newest inventions and developments in the electrical field were shown for the first time, and there was much that appealed to the purely technical man and the student of electricity.

Attendance throughout the two weeks was very large, even during the extremely bad weather of the first week. The electrical industry in its various branches was represented by visitors from all parts of the country, and the exhibitors were not confined to Chicago, but came from the whole country; and there were also exhibits of some foreign products.

The special days at the show brought out large throngs. On Franklin day, Thomas A. Edison day and Telephone day the management gave out some very neat souvenirs. There were also several conventions and meetings of electrical men during the exposition, among these being the very successful annual convention of the Northwestern Electrical Association, and the organization meeting of the Chicago branch of the Illuminating Engineering Society. These are reported elsewhere in this issue.

A large gathering of the Sons of Jove was occasioned by the show and an enthusiastic rejuvenation was enjoyed, 43 new members being added to the ranks. An effort will now be made to form a Jovian Club in Chicago. This will provide weekly lunches and a monthly meeting for rejuvenations and to listen to matters of interest to the members. Mr. Blocker, W. P. Crockett and A. O. Einstein are on the committee arranging this work.

Central-station men were greatly interested in the hew illuminating devices recently developed and some of them show for the first time in public. The ladies were attracted by the demonstrations in household cooking and heating devices, and the numerous motor-driven machines,. Telephone men had an opportunity to inspect the very latest telephones, switchboards and parts.

SPECIALTIES.

One of the interesting exhibits was that of the Peirce Specialty Company of Chicago. The display was made up entirely of the company's regular steel construction material, the framework consisting of channel and angle steel of the various sizes used in the manufacture of its different labor-saving products. Mounted in the steel frame were two-point Peirce brackets carrying leads from a 15-foot pole erected in the center of the space. Strung from these leads was a number of electric lamps. At the pole these leads terminated on the company's standard distributing circle. This is the well-known Peirce circle top of the type that may be erected, carrying only points sufficient for the need at the time of erection, permitting additiorial points to be added from time to time till a capacity of 48 pairs is reached. In order to demonstrate the great saving in time effected by the use of the Peirce hammer drill, a block of stone weighing nearly 1,000 pounds was used. In the block of stone holes were drilled with the hammer drill, and Peirce expansion lead bolts were set. In no instance was the time consumed greater than one minute. Also on exhibition was a model ten-pin pole route equipped with the different methods of transposition, clearly illustrating the advantages of transposition brackets. In attendance were C. L. Peirce, Jr., president of the company; Al Haase, sales agent; A. J. Kusel, R. L. Crane and H. E. Ward.
