You say the sluices which admit water to wheels or factories shall be kept closed from six o'clock on Saturday night to six o'clock on Monday morning. How, then, are the repairs of shafting and machinery to be made? These are generally done when the workpeople have gone home on Saturdays. Besides, what is your object?
This means that in no industry will over 75 per cent. of the machines or machinery employed be in average operation. The entire shafting in the shops must be kept in operation the entire year, often for less than 50 per cent. of the machinery.
The bevel gearing is revolved by shafting connected with pulley wheels and belting, the wheels being 3 ft. and 1½ ft. in diameter, and 6 in. broad. The driving engine is placed at one end of the building. Each vat requires from 2½ to 3 horse-power, or in other words, an expenditure of 1 horse-power per ton of ore treated.
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.
Two or three sturdy, courteous men helped us carry our cargo, by an intricate official route, over coils of rope and chains, over lines of shafting, and along dizzy walks overhanging the yawning basin; while the Doctor, directed to a certain chute in midstream, took unladen Pilgrim over the great dam, with a wild swoop which made our eyes swim to witness from the lock.
Katubwé, the northern hill on the left bank, had been bought, together with Akromasi Point and the Avin valley, by the late M. Bonnat, who cleared it and began shafting it for gold in the usual routine way. During the last six months it has been overgrown with dense vegetation. Mr. Walker believes, not unreasonably, that this lode is connected with the Apatim or Bujiá reefs.
It is also a manufacturing center possessing extensive rolling mills for the manufacture of railroad materials. It has iron foundries and steel shafting works. The city occupies the site of Fort Cumberland, which by order of General Burgoyne at the beginning of the French and Indian war, Braddock constructed as a base for his expedition against Fort Duquesne.
In either instrument, the semi-major axis C X is equal to S R, and the semi-minor axis to S P. The two sections of shafting, A and B, have each a flange or collar forged or keyed upon them; and in each flange is planed a transverse groove.
He was sorry, in a way. He liked the work. It was fascinating to put shafting and gears and a motor and a set of insentient wheels together and make the assembled whole a thing of pulsing power that leaped under the touch of a finger. But a good salesman made thousands where a good mechanic made hundreds. And money was the indispensable factor to such as he, who had none.
Building progressed slowly during the bad weather, but before the end of December the horse barn, the woodshed, the granary, the forage barn, and the power-house were completed, and most of the machinery was in place. The machinery consisted of a fifteen horse-power engine, with shafting running to the forage barn, the granary, and the woodshed.
