Dynamite Box

Dynamite box, paten pin & wedge (part of "Pickles" mining display), June 2007

The company made their own paten pins in the machine shop since it was cheaper to make them than to buy them. The miner would drill a hole, put in the paten pin, and the wedge would hold it. The miner made sure the pin wasn't too far in the hole so it could be removed. These were used throughout the mines in all kinds of work and repairs.
