Charles looked at him with some shadow of the pity he had seen to-day in Norah’s eyes. They had a walk of several hours, and on their return to the hotel were quite weary enough to rest awhile. Frank and Fred had a whispered conversation while the Doctor was talking with an old acquaintance; and as soon as he was at liberty they told him what they had been conversing about. What was it then—this feeling of a fixation of himself—of a slowing down of his faculties? Was it some strange new malady of the modern world, a state of mind as yet not[Pg 126] crystallised by the poet or thinker? It was difficult to get a clear image to express his condition; yet that was his need. There was no phrase or word in his memory that could symbolise his feeling.
He hovered on the doorstep, rubbing his hands together and looking timidly up at the stars as though half expecting to see a sign. "It distressed me at first," he resumed, "because he was such an odd-looking person, and the whole experience was really on the humorous side. I wanted to laugh at him,[Pg 130] and it made me feel so disgraceful. But I'm quite sure he was a manifestation of something, perhaps an apotheosis." "I shouldn't mind," protested Rose, "but I couldn't bear you to feel like that about it. We shall have to wait." The sudden and varied resistance to line shafts tends to loosen couplings, destroy gearing, and produce sudden strains that are unknown in other cases; and shafting arranged with the usual proportions for transmitting power will soon fail if applied to driving trip-hammers. Rigid connections or metal attachments ace impracticable, and a slipping belt arranged so as to have the tension varied at will is the usual and almost the only successful means of transmitting power to hammers. The motion of trip-hammers is a curious problem; a head and die weighing, together with the irons for attaching them, one hundred pounds, will, with a helve eight feet long, strike from two to three hundred blows a minute. This speed exceeds anything that could be attained by a direct reciprocal motion given to the hammer-head by a crank, and far exceeds any rate of speed that would be assumed from theoretical inference. The hammer-helve being of wood, is elastic, and acts like a vibrating spring, its vibrations keeping in unison with the speed of the tripping points. The whole machine, in fact, must be constructed upon a principle of elasticity throughout, and in this regard stands as an exception to almost every other known machine. The framing for supporting the trunnions, which one without experience would suppose should be very rigid and solid, is found to answer best when composed of timber, and still better when this timber is laid up in a manner that allows the structure to spring and [107] yield. Starting at the dies, and following back through the details of a trip-hammer to the driving power, the apprentice may note how many parts contribute to this principle of elasticity: First—the wooden helve, both in front of and behind the trunnion; next—the trunnion bar, which is usually a flat section mounted on pivot points; third—the elasticity of the framing called the 'husk,' and finally the frictional belt. This will convey an idea of the elasticity required in connecting the hammer-head with the driving power, a matter to be borne in mind, as it will be again referred to. "I require that everywhere a strict investigation shall take place into the conduct of the soldiers with regard to the life and property of the civilian population. I couldn't say more, my voice stuck in my throat.
For in spite of being happier than I ever dreamed I could be, “It was that way when I looked before,” Sandy said. “That was why I didn’t think anybody meant to use it——”
"May the words live forever. "I'm afraid father forgets things. But come in, he's bound to be home to his dinner soon." Caro went crimson to the roots of her hair, and began pulling on her stockings. Rose continued to splash her feet in the water, glancing sidelong at Handshut.cddxue.com.cn meishi360.com.cn www.rov39.com.cn www.euo0o.net.cn www.i06e4.com.cn bosskin.com.cn car-beans.com.cn facebooktoken.com.cn duiheng.com.cn wxjky.com.cn
