CD 116
  • Wide Squared Wire Ridges Variant
    This is the wide squared wire ridge variant, which first appeared in the 2008 price guide. Note the deeper, more prominent wire groove lips. Presumably they modified the mold in later years to better hold the tie wire.
Insulator Facts

Dimensions:4 1⁄4" H × 2 7⁄8" W
Primary Embossings:The Primary Embossing is typically found on the front of the insulator and usually identifies either the manufacturer (such as "Hemingray") or the company that the insulator was made for (such as "AM.TEL.&TEL.CO.")

Insulators with No Name or No Embossing are denoted as such.

Insulator Overview

This is an odd early Hemingray style nicknamed the "Three Rumple" by collectors. This is the only Hemingray style that references more than two patent dates. This style was officially Hemingray No.54 in a 1915 Western Electric catalog, but no specimens exist with this embossing. Based on multiple molds having "A.U." blotted out (American Union), it is believed some of these may have been modified from CD 121.4 molds. It's also interesting to note that so far we have been unable to locate any related patent applied for on or around the date of July 1st, 1882.
Known Embossings (10)
Primary EmbossingThe Primary Embossing is typically found on the front of the insulator and usually identifies either the manufacturer (such as "Hemingray") or the company that the insulator was made for (such as "AM.TEL.&TEL.CO.")

Insulators with No Name or No Embossing are denoted as such.
EINThe Embossing Index Number (EIN) is a unique number assigned by the collecting hobby to each distinct embossing for an insulator design. It is normally shown in brackets, e.g. [050].
EmbossingMost common terms:
(F-Skirt): Front Skirt
(R-Skirt): Rear Skirt
/: New line of embossing
{}: Special note (not embossed on the insulator)
[#]: Represents a number

Other terms:
{MLOB}: Mold Line Over Base
(F-Crown): Front Crown
(R-Crown): Rear Crown
(F-Umbrella): Front Umbrella
(R-Umbrella): Rear Umbrella
BaseThe base is the bottom of the insulator. Hemingray made 4 different types of bases:

1. SDP: Sharp Drip Points
2. RDP: Round Drip Points
3. CB: Corrugated Base
4. SB: Smooth Base
Year AddedThis is the year that this embossing was officially recognized and added to the McDougald (1991-2008) or Briel (2011-2023) insulator price guides. It is not necessarily the year this embossing was discovered.
