Those small ones were stand-off's for the cables route down to the grounded metal rod in the dirt by the barn. I have a lot of insulators and lightning rod stuff up North. The lightning rod balls are great collectables and I even have one glass side pendent for lightning rod balls here in my office. It is the only one I have ever seen, because they had metal hangers in a screw cap - that let rain water in, then they were broken when the water froze breaking them. Lightning rod items are a collection field all it's own. RED Matthews
Red, thanks for the info. I was up in Elmira over the holidays, and I was traveling up the Miracle Mile and noticed that every telephone pole next to the RR tracks was still loaded with insulators. Every telephone pole had an average of 4-5 crossarms with roughly 8-10 insulators on each cross arm. I estimated roughly 40-50 insulators still on each telephone pole. Have you ever seen these? I know you are familiar with this area.
Kevin. Here are his comments. He is extremely knowledgeable and honest. If you are interested in parting with it please PM me and I'll give you his contact info. *******************************************************************************These spools and pins were specifically used in mines.There are two sizes (diameter) of the shank that fit into the spool.As you can tell from the pictures the top end of the pin had a pair of ears or tabs that fit through the hole in the spool.After the pin is inserted it is turned 90 degrees and the tabs would fit into the depressions in the spool.As long as the pin was hanging down (a ceiling installation) the spool would stay in place. In other installations a spring was added to keep the spool pressed against the tabs.Generally, holes were drilled into the rock and the triple edged pin was driven into the hole. That spool has embossing that I haven’t seen before.**************************************************************************************
