In the case of the turbine steamer several of the forms of screw which were first proposed when that type of propeller was invented will again come up for examination, notably the Archimedean screw, wound round a fairly long piece of shafting. The larger the circular area of this screw is the less will be the risk of "smashing" the water, or of losing hold of it entirely in rough weather.
That it needs only deep shafting and drilling to unearth more remarkable riches than even Missouri herself has as yet yielded up, is evident from the outcrops' by the way, gentleman," Madeira here interrupted himself to say, still in his quiet, dispassionate tone, "Salver has spent a good many days in the hills lately, and he has decided that the deeper-seated sulphides are just as surely in the hills as are the carbonates.
Subdivide these same shops into as many small units as possible, and the current necessary to operate the shafting for this idle machinery will be saved, besides the saving from frequent stops while the machinery is in active use. To return again to the list, the next two applications, picture frame manufacturers and moulding manufacturers, are very similar.
I will see to that," he replied. "Give me a few minutes while I go to the hotel and change my suit. I have been putting in shafting with the men, and am hardly presentable in my present condition," he laughingly added. "I am putting you to great inconvenience, I fear, Guy; but I cannot help it, for it will not do to send word that I will not go back till he is gone." "No, certainly not.
They could be curved to suit any peculiarity of the situation; and when the pipes were lapped with felt, or enclosed in wooden troughs filled with sawdust, the loss of heat by radiation was reduced to a minimum. The loss of power was certainly much less than in the friction of a long and perhaps tortuous line of shafting.
Sitting here by the office window, with the smell of ink in one's nostrils, with the steady monotonous clatter of the linotypes in the ears, and the whirring of the shafting from the press-room in the basement throbbing through one's nerves, with the very material realisation of the office around one; we feel that only a small part of it, and of the life about it, has been set down in these sketches.
Overhead the shafting ran in rapid revolutions, communicating its power and speed by lengths of swaying, sagging belts to the machinery that stood so closely packed on the vibrating floors, and between which passed, and behind which stood, the operatives, unconscious of danger, and with scarce a care than how to keep pace with the speed of steam and the flying hours.
The funny part of it is that by a very little work Olsen is a good man with a drill and powder, you know they did enough linear shafting to enable me to patent the ground. And in the five months that I have been at work on the extensions I have done enough work on each of them to patent them also. That's what I wanted this six hundred for.
Indicating a general idea of what he desired, he applied to one of his workmen, a man of intelligence and skill in his craft, but without a conventional education. The man constructed the support, a triangular framework contrived to receive the shafting at the apex; where there was no stress within the triangle, he cut away the timber, thus eliminating all surplusage of material.
This motor was driving the shafting for 30 machines, and as the average operators employed the year round will not exceed 75 per cent. of the shop capacity, it will, I think, be entirely fair to estimate the average volts per machine rather than per operator, as the user of the motor has contracted for power sufficient to drive his entire plant.
