- Description
- (a) Telegraph insulators with a clear glaze on a white ceramic body with the CPR (Canadian Pacific Railway) monogram. The wooden pin is present with the object. This object would have been used along the Canadian railway. The insulators have been threaded and are designed to sit loosely upon a wooden pin. This style of insulator was a later, more modern version, manufactured in a beehive shape with a threaded interior cavity, which was then turned securely onto a matching threaded wooden pin. This allowed the insulators to remain securely in place so that they wouldn’t pop free staying locked into their wooden pins. The insulator has “C.P.R.” monogram has been stamped/printed in black ink on the tip of the body. Around the circumference of the body there is slot or groove formed into the insulator where the wire would have been wrapped around the groove. (b) The wooden base, acting as a pin, has two holes through the body to adhere it to the posts. The wood base also has screw threads cut into the body so that it can be affixed to the ceramic insulator. The size of the wooden pin would have depended greatly on the voltage to be isolated and the weight of the span of wire to be supported.
