CD-139 - Combination Safety w/drips!       Sold For: $11,110       Color: Blue aqua.

This rare CD style is found offered by Brookfield in an early trade journal advertisement. The design of this insulator closely resembles a patent issued to Edward Schoenthaler in 1903. The Brookfield advertisement, circa 1909, pictures this insulator and states, Combination Safety—Designed to prevent dropping of line wire to cross-arm if the tie wire breaks, and to eliminate the necessity of tying to every insulator. It further states, With or without drip points. We are aware of six CD 139s, ranging from good to damaged condition. Of the six, there are three smooth base Combination Safety's and only two containing drip points. The sixth smooth base example has a slightly different mold design and is embossed with 'Safty' rather than 'Safety'. The 'Safty' was likely the original prototype, followed by the second variant offered here with the vulnerable weak points at the arms beefed up. The drip points were added as an option. This is one of those rare CD styles that seldom changes
