Ajax Line Material Company arc lamp fixtures

Ajax Mast Arms.

With the rapidly increasing cost of poles, and the growing sentiment against wires crossing the streets, the use of center-suspension lamps is decreasing. Similarly, the need of neat, firm and low-priced fixtures for supporting the lamps at some distance from the poles is steadily increasing.

The range of conditions to be met in modern practice is well shown in a series of fixtures made by the Ajax Line Material Company of Chicago. These range from the Ajax front fixture (Fig. 1) with its two-foot reach, to the Ajax medium mast arm (Fig. 2), built in lengths of 8 to 14 feet. The latter is also made with additional bracing for lengths up to 20 feet. The Ajax midget mast arm answers for the 4 and 6 foot lengths. Both of the last-named types are fitted with safety pulleys, while the front fixture is usually equipped with the high-voltage type of the Ajax arc-lamp insulators
