MURDOCK CABLE INSULATOR.

A simple cable insulator capable of holding a number of sizes of cable is shown by Fig. 24. The insulator is made by H. D. Murdock, of Pittsburg, Pa., and is in two pieces, each beveled to a square shape at one end. When the two pieces are put together the beveled edges form sides of a square slot between the faces of adjoining insulators, in which the cable is clamped; the opposite grooves are corrugated so as to afford a good grip on the cable. By tightening or loosening the upper half of the insulator all sizes of cable from 300,000 cir. mils to 1,000,000 circ. mils can be securely clamped and held in position. The insulator is made sufficiently strong to withstand the strain of the largest cable it is designed to hold. A smaller insulator of the same design is made to hold cables from Nos. 00 to 300,000 circ. mils
