Item: 28 Description: Cooke’s Sleeve. William Cooke built the world’s first commercial telegraph line in England in 1837 using insulated cable buried in the ground. When the cable failed, he patented this insulator in 1842. The wire passed through the insulator (View 3) and a staple was driven around the groove to hold the insulator in place. Most examples are clay colored like the one at the right in View 4. Orange colored glazes are much rarer. View 2 shows the flat bottom of the insulator. Estimate: $300 - $400 Open: $150 Price Realized: $190 |
