Description

#3590        Unmarked.      Mt. Washington "rams horn."        Colorless glass.

A great example, still retaining a portion of the wood block that the iron/glass insulator was mounted in.  Most often these primitive insulators have been found with no wood remaining.

Due to the extensive usage of this type insulator having taken place on the slopes of Mt. Washington in New Hampshire, they have been nicknamed the “Mt. Washington rams horn.”

A threaded iron shell was molded first. Then the interior of the iron shell was filled with molten glass. While the glass was still pliable, an iron stem with rams horn shaped end was inserted into the glass. This resulted in a peculiar shaped insulator which was then placed inside a large wooden block.

Most of the this type insulator have been found on Mt. Washington, but a very limited number are reported to have been found elsewhere in New Hampshire. Their sturdy construction and durability made them especially suitable to the extreme weather conditions found on the mountain. Winds up to 231 miles per hour have been recorded on the mountain top! That, along with abundant snow and ice, resulted in the Mt. Washington communication line being among the most heavily challenged anywhere in the world.

The wood adds to the desirability and appeal.... certainly a candidate for anyone seeking an example above and beyond the usual examples. 

Third image is an 1800's view of the cog railway that traversed up the west side of Mt Washington in New Hampshire.  Short posts were fastened to the trestlework at left, and the wood block rams horns then nailed to the posts.

Metal has the typical rusted surface.
