I twisted the shafting one way and the tube the other as far as I could, and pinned them together. In this way, by straining the whole outfit up to its elastic limit in opposite directions, the torsion was practically eliminated, and after that the governors ran together all right."
The land is not heavily timbered, but there is wood sufficient for everyday purposes. Its chief growth is the spiny bombax, whose timber is hardly durable enough for permanent shafting. Here, however, and in all the mines upon and near the seaboard, carpenter-work should be imported from England; it will be at once cheaper and better.
The loss of power in this system has already been reduced to less than that which occurs with shafting, unless under the most favourable circumstances; and in places where the works are necessarily distributed over a considerable area the advantage is so pronounced that hardly any factories of that kind will be erected ten years hence without resort being had to electricity, and small motors as the means of distributing the requisite supplies of power to the spots where they are needed.
He also provided for the simplification of the hangers and fixings by which the shafting was supported, and introduced the "half-lap coupling" so well known to millwrights and engineers. His partner entered fully into his views; and the opportunity shortly presented itself of carrying them into effect in the large new mill erected in 1818, for the firm of MacConnel and Kennedy.
Both of us came to the conviction that the 'Izrah Concession' will pay, and pay well. But instead of the routine shafting and tunnelling it must be treated by hydraulicking and washing away the thirty feet of auriferous soil, whose depth covers the reef. The bed of the Fía will supply the water, and a force-pump, worked by men, or preferably by steam-power.
The above experiment took place between three and four o'clock on a Sunday afternoon, and within a few hours he had gathered his superintendent and men of the machine-works and had them at work on a shafting device that he thought would remedy the trouble. He says: "Of course, I discovered that what had happened was that one set was running the other as a motor.
When taken from the shafting the child was in a moribund state, with scarcely perceptible pulse, and all the accompanying symptoms of shock. Her injuries were dressed, the fractures reduced, and starch bandages applied; in about six weeks there was perfect union, the right leg being slightly shortened. Six months later she was playing about, with only a slight halt in her gait.
And yet the visible agents are not the sources, but only the vehicles of the power, the belting and shafting which transmit a mighty impulse which they had nothing to do in creating. And the antagonism subserves the purposes of the rule which it opposes, as the blow of the surf may consolidate the sea-wall that it breaks against.
I do not know of any instance of sewing machinery in a factory being driven by an electromotor, but such means of conveying motive power appears admirably adapted for that purpose, when the stitching room happens to be far removed from the main shafting or engine.
All these hypothetical correlates of force, therefore, predicated upon the doctrine of force-transmutation, have no foundation in fact, since the force transmitted from the point of generation to the point of expenditure undergoes no change but that of direction, in its passage along rope, wire, belt, pulley, shafting, etc.
