Maine Hub and Manufacturing Company producing birch insulator pins

Birch Telephone and Telegraph

Cross-arm Pin.

To supply the large demand existing among wagon manufacturers for a birch hub, which is of such well established good reputation for durability, the Maine Hub and Manufacturing Company of St. Marys, Pa., about a year ago purchased a large tract of birch timber in Maine and there equipped a factory with modern machinery for hub production. This factory has been running on wagon hubs for over a year with great success. But from the fact that birch as a material for hubs has been so well tried for years by the world's largest manufacturers and has proved so reliable in arduous service, and under the severest climatic conditions, the Hub company was led to the conclusion that birch is a wood from which durable telephone and telegraph insulator pins could also be produced.

Birch Cross-Arm Pin.

The Maine Hub and Manufacturing Company is, therefore, now entering the field with this new birch pin, confident that it is equal in every respect to the best locust pin in the market. The company's large mill in the Maine woods is fully equipped with modern pin-producing machinery and the Maine Hub company is now ready to make quick shipments to any part of the United States. This birch pin has been tested as to tensile strength etc., and a critical inspection of samples, which will be furnished on application, will reveal its merits.
