Woodhouse and Rawson patented earthenware wire insulator.

INSULATORS AND SUPPORTS FOR ELECTRIC LIGHT WIRES. —The sketch above illustrates a neat and simple form of earthenware insulator for holding fast electric light wires in factories, tunnels, or along walls generally. It is manufactured in such a way that by the insertion of a knife-blade into a crevice, which is left all round it, the insulator divides into halves. The wire can then be laid in one half, and the other closed over it, and all may be made firm and securely attached to any supporting body by driving in a gas-hook, as shown. The patentees are Messrs. Woodhouse & Rawson, and doubtless their cheap and simple device will prove of service in electric light installations.
