NEW Book    Collector's Guide for Porcelain Insulators    NEW Book

 

This 2015 book is the newest Guide Book for unipart (one-part) pin-type porcelain insulators.  It is like no other book about porcelain insulators.  This is the culmination of more than 45 years of research and nearly 5 years of work to write and photograph all known unipart styles.  The 1012 pin-type styles are shown in COLOR using reference photographs of actual insulators.  The Unipart Chart has been reduced by 20% by removing most of the trimmer variants and styles assigned from catalogs that did not match actual insulators.  It has a very detailed history of each manufacturer with nearly 500 historic and other photographs many of which are in color.  Every aspect of unipart pin-type porcelain insulators is discussed as well as examples of 286 types of markings that have been reported.  Mike Spadafora wrote an Appendix section summarizing his decades of  hunting and researching Fred Locke insulators and digging in the Victor plant dump.  He tells how you can determine the approximate year of manufacture by glaze and manufacturing characteristics. 

The book is 278 page book is spiral bound so it will lay flat when opened.  The size is 8-1/2 x 11.   The book is available NOW!

Lapp Museum at LeRoy, NY (May 1993)  When I was doing research for the Fred Locke book, I went to Victor, NY in May 1993.  Part of the trip was to the Lapp factory in LeRoy, NY with the sole purpose to visit the Lapp Museum, which was set up by Brent Mills.  Click on the link to see the photos of the museum.

Insulator Research Service: If you have an insulator you would like to learn more about, please feel free to contact the Insulator Research Service (go to www.insulators.info/irs).  I can send you links to make your own Patent copies.  The IRS is a good resource if you are designing an insulator display and would like additional research or copies of advertisements (over 1200), trade journal articles (over 1000) and patents (over 2800).  No fees are charged if you are building a display or doing research for future article.  Please be aware that no patents were granted for threadless insulators and very few specific insulator CD styles.  Click on the IRS link above to see a nearly complete list of CD styles covered by patents or click on this link to go to the patent database: Insulator Patents and do your own searching.  The IRS has copies of more than 2800 insulator related patents which includes more than 300 patents dealing with Lightning Rods: Points, Insulators, Ornaments (lightning rod balls), Conductors, and Rod Supports.
