About Me: Displays: 2012 Kansas City National  
Back to Displays  

This was my most recent display, and my first National display since 1996. Titled "Undercover Hemingrays", this was essentially a rebranding of my 2005 Cayucos Show display, which focused on insulators manufactured by Hemingray that aren't actually embossed "Hemingray" or "H.G.CO.". Since my 2005 display, I had acquired a couple dozen additional pieces, which required me to add a second display cabinet for spools and wall tubes.

I was very grateful to win the First Place award for the Specialty category!

At first glance, this may look like just your average display of Hemingray insulators. But look again! Not a single insulator here bears the iconic name “Hemingray” or even “H.G.Co.” Did you know that out of 170+ CDs attributed to Hemingray, only about 60% of them identify their manufacturer by name?

Flash back to the year 1871—December 19th, to be exact. On this day, Robert Hemingray was granted a patent for a glass insulator molding technique (U.S. Patent No. 122,015). Almost all of Hemingray’s earliest pieces are solely embossed with this patent date. Hemingray also manufactured insulators for A.U., B&O, Chambers, Seilers, T-H.E.Co., W.E.Mfg.Co., and W.U.

In the 1880s, Hemingray began embossing their insulators with “H.G.Co.” During this time period, they also manufactured insulators for other companies as well: F.M. Locke & Co., New Eng. Tel. &Tel. Co., S.S.&Co., and S.B.T.&T.Co. are some notable examples.

1893 was another significant year for Hemingray: on May 2nd, Ralph G. Hemingray and James C. Gill were awarded the patent for drip points (U.S. Patent No. 496,652). Hemingray began embossing virtually all of their drip-pointed products with the May 2, 1893 patent date. Beginning in the 1900s, Hemingray used stamped lettering, making embossed products easily recognizable from this point on. In the case of styles that were produced by both Hemingray and Brookfield, such as the CD 121 Am.Tel.&Tel.Co. and CD 147, the embossing style will give away a Hemingray every single time.

In 1933, Hemingray became a division of Owens-Illinois. Consequently, any insulator bearing the Owens-Illinois logo was manufactured by Hemingray. In the 1940s, Hemingray produced a line of insulators bearing the “Lowex” trademark, which stood for Low Expansion—Low Expense, a reference to a new type of glass being used. The trademark appeared on several Hemingray-embossed styles, but also appeared on its own. And finally, in the 1950s, Owens-Illinois’ Kimble line of power insulators was manufactured at the Hemingray plant in Muncie, Indiana.

Despite all this talk of embossings, many insulators manufactured by Hemingray were never embossed at all! For example, the majority of Hemingray’s break knob spools and floor/wall tube insulators were never embossed, despite catalog drawings showing the contrary. There are also many Hemingray insulators considered to be “no names” due to an engraving error. For instance, the CD 154 No Name in which “Made in U.S.A.” appears on both sides of the insulator. These types of embossings are often quite scarce and demand a premium over their correctly-embossed brethren.

Put all of these insulators together, and you have quite a wide variety of styles manufactured by Hemingray from the 1870s to the 1950s that never even mentioned the glass company that produced them. These are the Undercover Hemingrays.
