Hemingray Insulators CD 155

CD 145-184

Side wire groove - Double petticoat

CD 155

Size: 92mm x 101mm (3.625" x 4")

Years produced: 1938-1967
Style (CD) scarcity: 9, 1,000+ common colors/markings
Intended use: Telegraph & Telephone
Style / catalog number: 45
Number of unique insulators: 23
Notes: The replacement for the wildly popular Hemingray-42 (CD 154). Advantages to the Hemingray 45 (CD 155) are that it has reinforced wire groves. This style was made from 1938 as seen in the odd [060] listing, until 1967 which was the last year Hemingray insulators were made.

Primary Embossing = Embossing on the front of the insulator, usually is that manufacturers name or the customers name. No embossing units will be noted as NO EMBOSSING. Units with no name but with numbers or letters will be noted as NO NAME.

Examples:
HEMINGRAY
S.B.T.&.T.Co
NO NAME
NO EMBOSSING

EIN = Embossing Index Number is a standardized way to identify each unique embossing.

(FS) = Front Skirt
(RS) = Rear Skirt
(DO) = Dome
(CR) = Crown
(FC) = Front Crown
(RC) = Rear Crown
(BG) = Between Grooves
(FA ) = Front, Above wire groove
(FB) = Front, Below wire groove
(BE) = Base Embossed
(FU) = Front Umbrella
(RU) = Rear Umbrella
(FCE) = Front Center
(RCE) = Rear Center
(TE) = Top Ear
(TOP) = Top of Pinhole
/ = Next line of embossing

There are unique characteristics of the insulator that are not related to the embossing, but is worth noting.

Examples:
Factory molded brass bushing
Flaired skirt
MLOB = Mold Line Over Base
Waffle top
Wide saddle groove

Base = the bottom of the insulator. It is noted in the following standardized ways.

SDP = Sharp Drip Points
RDP = Round Drip Points
CB = Corrugated Base
SB = Smooth Base

= Insulator has been verified that exists
= Insulator has been verified that exists, but not listed in the "guide"
= Insulator has not yet been verified as existing
= Suspected error listing in the "guide" because listing does not match up with known manufacturing practices. Such as numbers and dots on an aqua insulator, or insulators listed with both factory molded brass bushing and without. Many do not come in both configurations and are listed as coming in both. Etc.

Color = The approximate color of the insulator. Due to manufacturing variations, insulators with the same color name maybe slightly different in actual appearance.

Details

Experimental unit from the Hemingray dump. The location of this insulator has not been known sense the 1970s. All that exist is a low res slide from the 1970s. Most likely a early prototype for the CD 155. Note, it has the No 42 Style. More info in this article.
