The threaded portion of this hanger is sowell protected that it is absolutely impossible for any moisture toget through into the insulation. When double-petticoat glass insulators were first placed uponthe market they became a universal standard, owing to theirhaving less leakage than any other insulator made at that time. The beaded skirt of The Gem is claimed to offer the sameamount of protection against the leakage of current as the doublepetticoat does to the glass insulator. Mechanical Power Brakes. The subject of brakes is one of the most important to be consid-ered in the equipment of the modern electric railway. That theincreased weight and high speed of the modern motor car demanda more powerful and effective brake than was necessary for slow-moving horse cars is generally admitted. Since the general adop-tion of electricity on street railways, various brakes have been puton the market, operating by compressed air, electricity and otheragents. One of the most widely adopted substitutes for the old-fashioned chain and spindle brake is the Sterling safety brake,made by the Sterling Supply & Manufacturing Company, of NewYork, and introduced about five years ago. Since that time thebrake has been extensively adopted, and its reliability and effi-ciency proved in service. A severe test of this brake hasbeen made at Troy, N. Y. The line of the Troy City Railway ex-tends for the greater part of its distance over a series of grades,some of them being ov
