Some New Locke Insulators


TWO new insulators, put on the market by the Locke Insulator Manufacturing Company, Victor, N. Y., are shown in the cuts below, one of them being a porcelain bus bar insulator for wire, tube, or flat bar conductor, supported either vertically or horizontally. This insulator is said to be ample for 12,000 volts. The cap is made of cast iron, cemented in place upon the insulator. The two studs are not attached directly to the cast part, but are threaded into a short steel bar which is attached centrally to the iron cap and, by swivelling, may be adjusted to any size bus bar up to 2 1/2 inches high by 2 1/2 inches wide. It is intended, when once the bus bar is in place, that superfluous length of the studs be cut off.

The porcelain supporting insulator, shown in elevation and section in the two lower illustrations, is designed for very heavy loads such as large storage batteries, electrolytic tanks, etc., and will stand a break-down test of 30,000 pounds or over. The insulator is furnished complete with cast iron cap at top and bottom.
