The more formidable weapons cannot be mounted upon ordinary vehicles, inasmuch as the increase in weight, which is appreciable, impairs the efficiency of the vehicle, and at the same time enhances the possibility of breakdown at a critical moment. For such arms a special and substantial chassis is imperative, while the motive power and gearing must be adapted to the circumstances.
Every connection with the main shaft, with its gearing and belts and pulleys by which colour-printing had before been accomplished was entirely done away with, because each machine had its own special engine. The former practice had led to much waste, and the printing was often confused and badly done.
I presume one of Dawson's men was working, unknown to his fellows, with the care and maintenance party, and another, equally unknown, with the engineers who were busy upon the gearing of the turbines. Many of the regular ship's officers and men would also have been on board. Had our remarkable friend his agents among them too?
Yes, it should run thus, the theme embroidered with high-flashing colour of Eastern reminiscence the great subtropic garden of the Sultan-i-bagh, for example, its palms, orange grove and lotus tank, the call of the green parrots, chant of the well-coollie and creak of the primitive wooden gearing, as the yoke of cream white oxen trotted down and laboriously backed up the walled slope to the well-head.
"To obviate the necessity of gearing to reduce the number of revolutions to those possible for a large screw, this member is made very small, and allowed to revolve three thousand times a minute, so that the requisite power is obtained with great simplicity of mechanism, which further decreases friction.
The mill itself, as regards the roll, is much the same as those of other firms; but instead of an engine with a heavy fly-wheel, always working in one direction, and connected to the rolls by double clutch and gearing, the work is done by a pair of horizontal reversing engines, in connection with which there is a very simple, and at the same time extremely effectual, system of hydraulic reversing.
One noticeable change in the front-steering tricycle, which has been largely made, lately, is the substitution of central for side gearing, in consequence of which bicycle cranks can be employed, instead of the cranked axle, with its fixed throw. This gives an appearance of lightness which the older types of machine do not possess.
Down below the transmission gearing gets out of order, and this prevents the mechanician from sending the trap up again. Then, up above, Bonnard gets angry, calls, and at last decides to go down in a fury when he finds that nobody answers him. Then Morange arrives, flies into a temper, and goes down in his turn, exasperated at receiving no answer to his calls for Bonnard.
In addition to the crank that corresponds to a throttle, there is a gauge on every vehicle, which shows its exact speed in miles per hour, by gearing operated by the revolutions of the wheels.
The yarn has certainly to be wound upon the bobbin and at the same rate as it is delivered from the drawing or delivery rollers, but in the spinning frame the bobbin, which rotates on the spindle, is not driven positively, as in the roving frame, by wheel gearing; each spinning bobbin is actually driven by the yarn being pulled round by the arm of the flyer and just sufficient resistance is offered by the pressure or tension of the "temper band" and weight.
