Item: 25 Description: Cooke’s Sleeve with typical color glaze. Grade B for some surface wear. This is the FIRST insulator ever patented… in 1842… two years before Samuel Morse built the first telegraph line in the US. The Cooke & Wheatstone Telegraph Company of England built a line for the London & Blackwall Railway in 1840, burying the line underground. The insulated wire failed and, in 1842, Cooke received a patent for this above-ground insulator. The groove in the center is for a metal staple to hold the insulator to a post, and the telegraph wire was threaded through the insulator. In View 2 the insulator is tilted so you can see the flat backside. View 3 is an endwise look, showing how crudely formed these are. View 4 compares the color of this one with Item 24. Estimate: $150 - $200 Open: $95 Price Realized: $165 |
