"The Loomis Electric System
The Eureka Electric Company (Loomis system), whose ingenious self-regulating system of electric lighting was described and illustrated in these columns about a year ago, have installed many important plants during the past few months. One of their most recent contracts is one for an installation of two thousand incandescent and several low-tension arc lamps for a large hotel at Tampa , Fla. A notable feature of this installation is the fact that current for both kinds of lamps will be supplied from the same dynamos. Another feature of this installation is that each bedroom in the hotel is furnished with a special incandescent night-lamp, which can be kept burning all night, and at any degree of brilliancy desired by the occupant of the room.
The engines, boilers, and dynamos are placed in a separate building situated some distance from the hotel. The boilers have a total capacity of 250 horse-power, and supply steam to two automatic high-speed engines of 110 horse-power each. These furnish power for four dynamos of five hundred lights each. The main switch is of special design, and controls all the lights, both arc and incandescent. It is so constructed that the dynamos can be run singly, in pairs, or in multiple, any desired combination being made in a moment. Four main circuits run from the dynamo building to the hotel through an underground conduit. Each circuit is provided with an ammeter and a ground detector, and each is connected, by a compound switch, with a voltmeter; so that the electro-motive force of all, or of any one, or of any combination of dynamos, may be quickly taken. As a whole, the installation is expected to be the principal electrical feature of Tampa .
The Eureka Company have also installed a plant at Duncansville , Penn. , one-half the output of the dynamos being used for arc lamps, the other for incandescent. They have also recently put in plants, incandescent or mixed, in Hollidaysburg, Penn.; Wakefield, Mass.; Peterson, N. J.; Bloomfleld, N. J.; Marcellus. N.Y.; West New York, N.J.; Portland, Ore.; Little Falls, N.Y.; Chester, Penn.; Pinkney, Tenn.; and quite a number of large plants in important business buildings in this city. The growth of their business has been so rapid and constant, that the company have been compelled to remove their factory from this city to larger and more convenient quarters in Brooklyn."
