An artifact from Transcontinental Railroad and telegraph history.

Emminger’s insulators come with lozenge-shaped projectors meant to retain dust and dirt from the insulator. It is popular for several of these common insulators to come with damaged or worn-out projectors. These insulators are also far more prone to breaking than comparable glass insulators.
