This is a "infant signal" applied in telephone and low voltage electrical and signal applications. The little letter mold set dates from 1938 and Hemingray made use of it until the 1950s, I assume. If you can deliver the numbers and dots we can date it more precisely.

Fred M. Locke had a significant interest in the insulator and electrical company where he patented lots of insulator designs, the initially getting the triple petticoat insulator patented on Could 7, 1889 along with John Lapp. There are quite a few CDs of Hemingray insulators that have extra dots on them. Several low voltage glass insulators created throughout this period have been formed in dark colored glass to compete with similarly colored porcelain products. My thanks go to my neighbor Lars, whose father collected these over the years.

I've incorporated the patent application letter beneath and it is exciting to read the reasoning behind the small "teats" as they were named by the inventors themselves. The “Stamp” molds are less difficult to inform apart from every other than the Prism molds are, simply simply because of the generally erratic placement of the stamped letters. The mold engraver had great difficulty in stamping the characters in Exactly the same position from mold to mold. “EVO” style embossings, which are rather hard to find, have been noticed in most of the exact same colors as the “Script” style. “EVO 1” can be identified by the oddly shaped “9”, shown here.

A, is the body of the insulator created of glass, porcelain or other suitable insulating material. In the latter half of the 19th century entrepreneurship was booming. Inventors, businessmen and industrialists have been forging ahead at full steam each trying to outdo his competitors in the new and expanding industrial based economy of a young America.



On most of the examples with the “Looped 2”, though not all, the embossing tends to be rather compact. These two varieties of the “2” are believed to reflect the perform of two various mold engravers. This style of insulator was broadly distributed across the United States, being applied practically everywhere, and can be located in practically each state in the nation. Nonetheless, I look to notice these are more often found in the Midwestern and Western states, and much less so in the Northeastern, East Coast and Mid-Atlantic states. This is an estimated value range only, primarily based on historical hobby collecting information. Insulator values vary broadly depending on many things, which includes embossing, colour, condition, mold variations, manufacturing anomalies, and other attributes.

Simply because of the erratic nature of the stamped letters, no two “STAMP” molds inside the index are definitely identical……each mold can be individually identified below close scrutiny. For instance, there is considerable variability in the positioning of the “9” below the name Hemingray. It may be found positioned straight beneath “IN”, “N”, “NG”, “G”, “GR”, “R”, “RA” or “A”. In some instances the 9 is positioned slightly to the suitable or left, such as “slightly to the appropriate of the letter G”.
