The first four applications on the accompanying list, viz., exhaust fans, blowers, ceiling fans, and fan outfits, are all more or less subject to the foregoing conditions, and therefore currents supplied to motors for these purposes command the maximum price per horse power. One important feature in the installation of ceiling fans is the countershafting to the motor.
Instead of the usual steam pump, a power pump of some approved design is substituted, and connected to the motor by suitable countershafting to give the required revolutions at the pump. The regulation of the motor in this case should be controlled by the position of water in the lower tank, as in the case of the steam pump.
In one recent case we had a complaint from a customer that the half horse power motor sent him would not drive the ceiling fans, and that the motor must be defective, and should he return it for repairs. We immediately sent a representative to find out the difficulty, which was found, as is usual in such cases, in the countershafting, or rather the want of it.
To Bonbright's eyes it seemed a tangle. A labyrinth of shafting, countershafting, hung from the high ceiling, from whose whirring pulleys belts descended to rows upon rows of machines below. It looked like some strange sort of lunar forest, or some species of monstrous, magic banyan tree. Here were machines of a hundred uses and shapes, singly, in batteries a scrambled mass it seemed.
