== Insulator of the Week == '''CD 211''' - ''Fri, 1 Feb 2008'' ==Nickname== No Leak ==Related Patents== {{Patent | number = 882,803 | patentee = Leonard W. Storrer | date = March 24, 1908 }} ==Details== Embossing: (f) Brookfield (b) No Leak D./Patented These are found in shades of aqua, green aqua and near green. Only a small number have been found with notable amounts of bubbles or inclusions. {{PicturePoster |id=178151641}} This is a two-piece design with a glass insert. As described in the patent info, the glass insert was designed to fit into the underside of the insulator to maintain a dry and clean zone within the inner skirt area, thus the name "No Leak". This, of course, was for the prevention of current leakage due to wet weather or the build up of debris, such as spider webs. Due to the fragile nature of the insert, there are many Brookfield No Leaks in the hobby that lack a matching insert. I'll stretch my neck out and say at least half, maybe more, of the No Leaks known are "insert-less", with some inserts having been repaired. {{PicturePoster |id=178151641}} It appears that a good number of the No Leaks found in collections today have originated from the Stampede Pass line in Washington State. Other reports indicate spotty finds near Norwich, NY and "near an oil refinery in CA". A special dual pin assembly is reported to have been used with this insulator on the Stampede Pass line: {{PicturePoster |id=115995826}} Following is a link from the Crown Jewels of the Wire archives. This [http://tinyurl.com/2rfpgm article] was written by Elton Gish in the May 1986 issue. Note the locations of the test lines. Anyone know of any being found specifically in these areas? Who knows, maybe the first ones tested were porcelain? There was a report in a 1970 issue of Crown Jewels that a rubber gasket or washer was found with a No Leak and insert. Can anyone verify that a washer was used?
