The lamps worked well but were short lived, requiring a small army of workmen to constantly replace them. Westinghouse Electric had severely underbid the contract and struggled to supply all the equipment specified including twelve 1,000 horsepower single phase AC generators and all the lighting and other equipment required. They also had to fend off a last minute lawsuit by General Electric claiming the Westinghouse Sawyer-Man based stopper lamp infringed on the Edison incandescent lamp patent. The International Exposition was held in an Electricity Building which was devoted to electrical exhibits. A statue of Benjamin Franklin was displayed at the entrance. The exposition featured interior and exterior light and displays as well as displays of Thomas Edison's kinetoscope, search lights, a seismograph, electric incubators for chicken eggs, and Morse code telegraph. All the exhibits were from commercial enterprises. Participants included General Electric, Brush, Western Electric, and Westinghouse. The Westinghouse Company displayed several polyphase systems. The exhibits included a switchboard, polyphase generators, step-up transformers, transmission line, step-down transformers, commercial size induction motors and synchronous motors, and rotary direct current converters (including an operational railway motor). The working scaled system allowed the public a view of a system of polyphase power which could be transmitted over long distances, and be utilized, including the supply of direct current. Meters and other auxiliary devices were also present. Part of the space occupied by the Westinghouse Company was devoted to demonstrations of electrical devices developed by Nikola Tesla including induction motors and the generators used to power the system. The rotating magnetic field that drove these motors was explained through a series of demonstrations including an "Egg of Columbus" that used the two-phase coil in the induction motors to spin a copper egg making it stand on end. Tesla himself showed up for week in August to attend the International Electrical Congress, being held at the fair's Agriculture Hall, and put on a series of demonstrations of his wireless lighting system in a specially set up darkened room at the Westinghouse exhibit. These included demonstrations he had previously performed throughout America and Europe including using a nearby coil to light a wireless gas-discharge lamp held in his hand. Also at the Fair, the Chicago Athletic Association Football team played one of the very first night football games against West Point (the earliest being on September 28, 1892 between Mansfield State Normal and Wyoming Seminary). Chicago won the game 14–0. The game lasted only 40 minutes, compared to the normal 90 minutes.
