CD | + | | align="left" |100|| || Electric Fence|| || 1945~|| 1955~|| <ref name="surge">CD 100 and CD 100.2 Crown Jewels, December 1985. http://cjow.com/archive/article.php?month=12&a=12Surge%20Fencer%20Post%20and%20Insulator.htm&year=1985</ref> <ref name="surge2">Per N.R. Woodward, as shared by Bill Meier on ICON, 12/20/2020: The first CD #100 insulators were embossed with the words "T.M.REQ.PAT.PEND", below the SURGE name, which is in large letters. This is not an error embossing as explained below. Later insulators replace this with the words "REG.U.S.PAT.OFF." |
- | ! Name | + | |
- | ! Application | + | During a visit to the facility on April 22, 1970, I was permitted to review a file which contained several documents relating to the fence insulators. One was a letter from their attorney advising that the marking T.M.REQ. (Trade Mark Requested) was not conventional, and should be changed to the normal REG.U.S.PAT.OFF., which obviously was done. Another was a letter from a patent attorney stating that in his opinion the insulator would not be patentable since it did not differ materially from the usual telephone insulators. It would seem that he was also correct, as Design Patent number 113,240 was rejected. Unfortunately I had no means of obtaining copies; and those files in all probability no longer exist.</ref>|| Unique to SURGE (1940-1978)|| 1967|| [NRW67] |

All Dwight Patterns are thought to be Brookfield products, but were never made in Old Bridge colors. This implies these stopped being made by 1906. Other CD 143s could have been made later.</ref><ref>per Barret Nicpon, 8/15/2016 on ICON: As far as the Dwight CD-143 use era, I would suggest that a general |
+ | turn-of-century window is probably appropriate for these pieces. This isn't | ||
+ | based on any written or historical data, but rather on my own digging | ||
+ | experience. They seem to have begun to be used sometime in perhaps the | ||
+ | mid-to-late 1890s, and their use was probably truncated by the beginnings | ||
+ | of G.N.W. TEL. CO. CD-145 production. These seem to have been in prolific | ||
+ | use by the early 1900s. I can't personally offer much assurance on the | ||
+ | accuracy of these dates, unfortunately. | ||
+ | |||
+ | As far as the use of threadless in Canada goes, I believe the magic date | ||
+ | for the switchover to threaded glass took place around 1875-1877, depending | ||
+ | on the company and individual line. Again, this is based on my own personal | ||
+ | experience of line construction dates compared with digging finds. This is | ||
+ | also based on correspondence with other collectors who have indicated | ||
+ | threadless glass can be found on even newer lines on rare occasions. This, | ||
+ | I assume, is an example of a frugal line superintendent or telegraph | ||
+ | company continuing to re-use new-old-stock insulators into more modern | ||
+ | eras. Overwhelmingly, it seems threadless were no longer being used by the | ||
+ | beginning of 1877 and had been replaced by early 143s, such as threaded | ||
+ | 743.x, Montreal Telegraph CD-143s, and other unembossed 143s.</ref>|| || 1969|| [NRW69] | ||

Revision as of 21:35, 17 January 2021
This is an approximate and incomplete list of dates that CDs were manufactured. If you can fill in some of the missing information, or correct mistakes, please do so!
- The Trade Name, Application, and Hobby Nickname are mostly from N.R. Woodward's "The Glass Insulator in America" Reports.
- The Start Date and End Date have four notations
- ">" which indicates the date is as specified or after
- "<" which indicates the date is as specified or before
- "~" which indicates the date is approximately
- dates in italics are our best guess, as opposed to fact based.
- The References state where this information came from
- Comments provides some additional information to help in the dating.
- The Assigned Date and Comments show the date of publication of the first reference showing the CD (again, note that this is approximate).
NOTE: Rows in gray deal with CDs that have been deleted, combined with other CDs, or for which there are no known examples.

- ↑ Per N.R. Woodward, as shared by Bill Meier on ICON, 12/20/2020: The first CD #100 insulators were embossed with the words "T.M.REQ.PAT.PEND", below the SURGE name, which is in large letters. This is not an error embossing as explained below. Later insulators replace this with the words "REG.U.S.PAT.OFF." During a visit to the facility on April 22, 1970, I was permitted to review a file which contained several documents relating to the fence insulators. One was a letter from their attorney advising that the marking T.M.REQ. (Trade Mark Requested) was not conventional, and should be changed to the normal REG.U.S.PAT.OFF., which obviously was done. Another was a letter from a patent attorney stating that in his opinion the insulator would not be patentable since it did not differ materially from the usual telephone insulators. It would seem that he was also correct, as Design Patent number 113,240 was rejected. Unfortunately I had no means of obtaining copies; and those files in all probability no longer exist.
- ↑ CD 102 Per N.R. Woodward on Hemingray
- ↑ CD 102.4 a product of the Lyndeborough Glass Company, South Lyndeboro, New Hampshire (1866-1888). Many shards have been found by a digger at the old glassworks site. Per David Whitten, 10/12/2009 email.
- ↑ "The CD 106 Hemingray-9 was introduced in either 1892 or 1893 and continued in production until at least the early 1950's (my example is 1951) until replaced by the CD 107 Hemingray-9 in 1956." Per Bob Stahr, 09/12/2007 email on ICON.

- ↑ "CD #122 came along in 1919-20, the change in design was the larger square wire groove; and corresponding greater outward slant to the skirt and slightly greater base width" N.R. Woodward on ICON, 12/14/2009.
- ↑ 11.0 11.1 11.2 " Hemingray offered their smallest "bullet", the CD 124.1 probably as early as the 1871 Patent they wear. It is believed the 124.2 superseded the .1 as early as 1873, with the 124.3 being offered by about the time the very first Brookfield produced "pony" was introduced in the July, 1878 Tillotson catalogue." Brent Burger in ICON 2009.10.15 digest.
- ↑ CD #129 should have a date of 1954. First ones were made that year by both Owens and Armstrong. The single-page brochure I have advertising the "TS" as a "new insulator" has a print date of 1955. Per N.R. Woodward on ICON, 10/16/2009

- ↑ Unsure when Canadian glass houses started using threads, but likely in the 1870s. All Dwight Patterns are thought to be Brookfield products, but were never made in Old Bridge colors. This implies these stopped being made by 1906. Other CD 143s could have been made later.
- ↑ per Barret Nicpon, 8/15/2016 on ICON: As far as the Dwight CD-143 use era, I would suggest that a general turn-of-century window is probably appropriate for these pieces. This isn't based on any written or historical data, but rather on my own digging experience. They seem to have begun to be used sometime in perhaps the mid-to-late 1890s, and their use was probably truncated by the beginnings of G.N.W. TEL. CO. CD-145 production. These seem to have been in prolific use by the early 1900s. I can't personally offer much assurance on the accuracy of these dates, unfortunately. As far as the use of threadless in Canada goes, I believe the magic date for the switchover to threaded glass took place around 1875-1877, depending on the company and individual line. Again, this is based on my own personal experience of line construction dates compared with digging finds. This is also based on correspondence with other collectors who have indicated threadless glass can be found on even newer lines on rare occasions. This, I assume, is an example of a frugal line superintendent or telegraph company continuing to re-use new-old-stock insulators into more modern eras. Overwhelmingly, it seems threadless were no longer being used by the beginning of 1877 and had been replaced by early 143s, such as threaded 743.x, Montreal Telegraph CD-143s, and other unembossed 143s.

- ↑ CD 342s were made in a single production run in late 1903. The very first CD 342 tops had no embossing and were likely prototypes made before the embossing was engraved. Note that unembossed bases were produced May - December, 1900 for the M-2795 gutter tops. CD 342s with unembossed bases are reconstructed from a CD 342 top and a M-2795 bottom.
