Steel Mine Car at One of the White Oak Shaft Mines
Description:
'All ready-Hoist! This is an end view of one of our new steel mine cars on a cage at one of the White Oak Shaft mines, and the signal has just been given to hoist it to the surface--450 feet up! These electric equipped hoists can hoist a car every twenty seconds and dump it! The cars are placed on the cages automatically by creeper chains and car stops. One man operates the signals and car stops and chains.'
'Coal at all White Oak shafts mines is handled on self dumping cages, which handle the coal uniformly and with a minimum of breakage. Note how evenly the coal is flowing from the mine car. Much more rapid of course than the picture indicates, but it shows how well designed the equipment must be to handle the coal in such splendid manner.'
