CD 249, HEMINGRAY, Aqua
With A. R. Hudson posting many great photos of the CD 249 No 0, PROVO TYPE insulators in service use, I thought I would post a front and reverse side of one from my collection.
The CD 249 is a large power insulator used for high voltage power distribution with a rating up to 50,000 volts. The Hemingray Glass Company in Muncie, Indiana produced these 0 Provo Type insulators in the early 1900's, and were used in service around the Pittsburgh, PA area.
The April 25, 1899 patent was issued to Vernon G. Converse of Pittsburg, PA for a design patent for a power insulator assigned to the Hemingray Glass Company. This was implemented in the CD 282 and 283 and later copied by U-372.
Embossing (F-Skirt) HEMINGRAY (R-Skirt) No 0, PROVO TYPE / PATENTED APRIL 25 1899
Index # 005

Not sure if I ever did have the CD 283 #1 Provo or not.
