Rolling

“ The aim is now to make the base-course as dense and strong as the surface-course.
24. The importance of proper and thorough rolling is not usually fully appreciated, and this part of the work is often shirked by the contractor. Not only should the heavy roller be at work as soon as the material will bear it, but the roller should, when work is progressing regularly, be kept at work all the time. It is a safe motto that the final rolling cannot be overdone. ”

“ Another play with wheels consists of whirling a small one on a string passed through its axis, a practice both ancient and modern; and, too, there is the beautiful sport of rolling blazing wheels downhill at night, as is the custom with many mountaineers. ”

“ Advantages and Applicability of Rolling.—Rolling uses very much less power than drawing, because the friction against the fixed die in the latter process is very great. For much the same reason rolling proceeds much faster than drawing, and on both these accounts it is incomparably the cheaper of the two. ”

“ Rollers, are also moveable pieces of wood, of the same figure, which are occasionally placed under planks, or long pieces of timber, in order to move them with greater facility either in the dock-yards, or in lading and delivering merchant-ships.
ROLLING, the motion by which a ship rocks from side-to side like a cradle, occasioned by the agitation of the waves. ”

“ Such belts are sometimes three or four rods wide, or they may be much wider, and are rolling and slightly raised above the adjoining clay land. Sometimes, instead of lying in belts, such rolling, gravelly land is spread out over areas of no definite shape or limit. ”

“ In the cold-water operation he sometimes employs a heavy pressing roller l, which, being mounted in slots in the frame or standard, revolve with the large drum, rolling over the back of the cloth as it goes round. ”

“ As you start rolling forward [Pg 82] push the control lever forward which will raise the tail off the ground and place the wings edgewise to the wind while they will not offer resistance to the acquiring of good rolling speed. ”

“ The end of a slip of metal is presented between the rollers while they are in motion, not on that side of the roller which would operate to draw in the slip between them, as in the rolling-press above described, but on the contrary side, so that when one of the flat sides of the under roller fronts horizontally the circumference of the upper roller, an opening is formed, through which the slip of metal is to be inserted until it bears against a fixed stop at the back of the rollers. ”

“ I never pass or hear a rolling machine revolving very rapidly without having vividly brought to my mind a very serious accident that happened to my father. He was feeling for a flaw on one of the rollers, and whilst his hands were at the edge of the rollers the man turned the handle, drawing the whole hand between the heavy cylinders. ”

“ Back again went the trolley, along the asphalted road past the Queen Anne villas with their terraced gardens, past bicycles, carriages, wagons, and always clouds of dust; out into the open country, with rolling meadow and upland on either side, simmering in the heat of the summer afternoon, to which the morning heat was as nothing; Elizabeth sitting upright, shading her eyes from the glare, with aching head and burning eyes, and throbbing brain that refused to take in the reality of what she had done. ”

“ He hurried over to a little clump of trees and came back with a short section of a round limb.
“This will be a roller for the rope to pass over, just like a pulley,” he announced. Then he proceeded to put his plan in operation. Lying down on his face, he held the log in position, the rope passing over it. ”

“ Now put on your roller and drive it down to the hub and see that the roller is free from the fork. See that jewel pin reaches fork properly and that the guard pin also reaches the roller. See that your balance is free from the plate and the bridge. If the balance is true and all right, you are ready to put on your hair-spring. See that it is in beat. It is well to make a mark on the balance before taking off the old staff, showing positions of hair-spring stud and jewel pin. ”

“ I feel good. Now
a stoic ice shines
in me.
It makes me laugh this ruby
rope
grinding in my body.
Rope without end,
like a
spiral
descending
from
evil...
bloody and left-handed rope
formed by
a thousand daggers in support. ”

“ The innocent wavelets dancing in the sun, pretty and sparkling, and the huge black rollers, whose crests under the weight of a gale, before they can curl over and break, explode into spindrift, are propagated by the wind blowing obliquely on the surface of the water. ”

“ I heard the sharp click of this against the spokes of the wheel, then the hum of the wheel, the buzz of the spindles as the twisting yarn was teased by the whirl of its point, then a step backwards, a pause, a step forward and the running of the yarn upon the spindle, and again a backward step, the drawing out of the roll and the droning and hum of the wheel, most mournfully hopeless sound that ever fell on mortal ear. ”

“ It was rope, and it gave way beneath my grasp. I caught at something again. It was a wheel and it turned round, but, as strange sounds, shouts, and cries reached my ears, I got hold of the cross beam, and somehow, by help of the wheel, managed to reach my old position, but crouching down and holding on for dear life.
"Below there!" shouted a familiar voice, but hollow and strange, "who is it?"
"I! Help! Help!" I gasped, now thoroughly unnerved.
"Right; can you hold on till we send you down a rope?" ”

“ The awning is manipulated by pulling the rope which unwinds, causing the roller to revolve and releasing the rope allows the weight of the awning to make the roller revolve the reverse way, winding up the rope. ”

“ Roe, s. A species of deer; the female of the hart; the eggs of fish; that of the male fish is called the soft or melt; that of the female the hard or spawn.
Roller, s. Anything turning on its own axis, as a heavy stone to level walks; bandage; in saddling, the broad fillet, with two or more straps and buckles to secure the saddle or sheet.
Rollypooly, s. A corruption of roll ball into the pool, a sort of game, in which when a ball rolls into a certain place it wins. ”

“ Now, the step from a simple supporting roller to a fixed roller, or wheel, appears a very easy one. At least it appears very easy to us who are accustomed from childhood up to the action of the wheel. ”

“ The driving rigger or pulley a, is fixed upon the front roller b, commonly called the drawing roller, because when pressed upon by the upper wooden roller c, it draws out the fibres between them. The rollers d, e, f, are the ordinary back or holding rollers, for retaining the fibres, while they suffer powerful traction [502] by the rollers b, c, over the needles or points of the heckle bars. The upper guide rail above mentioned, upon which the heckle bars slide, is shown at g, in fig. ”

“ The rollers now begin to turn and to deliver threads, which receive immediately a portion of their twist from the spindles; the carriage retires from the roller beam with somewhat greater speed than the surface speed of the front rollers, whereby the threads receive a certain degree of stretching, which affects most their thicker and less twisted portions, and thereby contributes greatly to the levelness of the yarn. ”

“ By turning the wheel any type can be brought to the front, and a stationary guide controls its descent as it makes the impression. An inking roller is seen on the right, which inks the faces of the type. ”

“ Fastened to the wheel is a cam, concentric for about seven-eighths of its circumference and indented for the remainder. Into a groove in the concentric portion of the edge is pressed a roller which is pivoted at the free end of a strong curved spring. When the mainspring is fully wound the roller rests in the curved depression of the cam and the effort required to lift the roller up the incline absorbs some of the mainspring's power. ”

“ The windlass, as I have said, revolved slowly, but it revolved persistently. If I would remain with my head above the well-rim—which, I freely confess, I had a morbid desire to do—I must swarm as persistently up the rope. That was an eerie and airy sort of treadmill: to climb, and climb, and always climb, paying out the cord beneath me, that I might remain in one place. ”

“ The drawing shows an endless rope passed over a roller attached to the side of upright posts, and at the extremities of the line over horse-whims; buckets are attached to it by thin ropes, spliced to the main rope. At each roller a rod is attached to a piece of the post, which, bending upward and outward round the roller, pushes the bucket-rope aside, and enables the bucket to pass by the rollers. ”

“ The sheets are then placed between tins, and the whole passed |11| between the rollers, which are regulated by a screw, according to the thickness of sections and power required. The workman, technically called “Roller,” has to be very careful in passing his books through, that his hand be not drawn in as well, for accidents have from time to time occurred through the inattention of the Roller himself, or of the individual who has the pleasure of applying his strength to turning the handle. ”

“ The fabric or goods to be operated upon being first wound tightly upon a roller, that roller is to be mounted upon an axle or pivot, bearing in arms or brackets at the back of the machine, as shown at D. From this roller the fabric a a a a is conducted between tension rails, and passed under the bed cylinder or paper bowl E, and from thence proceeds over a carrier roller F, and over steam boxes not shown in the drawing, or it may be conducted into a hot room, for the purpose of drying the colours. ”

“ We have noticed that in order to favor the impulse we require a large roller, and for the safety action a small one, therefore escapements made on fine principles are supplied with two rollers, one for each action. ”

“ Another useful application may be mentioned; in flatting mills, where one roller is driven by a pinion from the other, there is a constant combat between the effort of the plate to pass equally through the rollers, and the action of the common geering, which is more or less convulsive. Whence the plate is puckered, and the resistance much increased, both which circumstances these wheels completely obviate ”

“ If you get a rope—a strong rope—and put a loop in it for your foot, and pass the other end of the rope to me around the staunchest railing of your balcony, I will let you down to the level of my own. Then you can easily swing yourself within reach. If you find you cannot climb back, I can help you, by pulling on the rope and you will ascend as you came down. ”

“ In ball bearings the load is concentrated at a few points, the points where the balls touch the race, and in the roller bearing at a few lines, the lines of contact between the rollers and the surfaces of the journal and bearing ”

“ This roller consists of a heavy piece of round wood, eight or ten feet long, to which a pole is fastened in the middle to have oxen harnessed to it. It is drawn slowly over the ploughed land, and presses the clods to earth. To give it greater force, the driver sits or stands upon it. ”

“ With such energy was that strong man cannonading himself through the air that at each extremity of his increasing arc his body, standing in the swing, was almost horizontal. Should he once pass above the level of the rope's attachment he would be lost; the rope would slacken and he would fall vertically to a point as far below as he had gone above, and then the sudden tension of the rope would wrest it from his hands. ”

“ In all continuous spinning the number of twists inserted into a given length of thread is governed by the surface speed of the front roller, relatively to the revolutions of the flyer, or to the speed of the winding surface. ”

“ Planted broadside, its four limbs—the massive wheels—hold the ground like a wrestler drawing to him the unwilling opponent. Humming, panting, trembling, with stretched but irresistible muscles, the iron creature conquers, and the plough approaches. ”

“ The rollers may be a spring shade roller mounted in the ordinary way, or a roller with a spool and cord, identical in principle with the roller shown in Figure 150, and the bottom of the curtain is provided with snaps to hold it in place when down. ”

“ The fact that the arm or detent, k, arranged on the roller in the manner described, moves towards and away from the center or axis of the roller in consequence of the motion of the roller itself, is not patentable independently of any useful combination in which it performs a necessary part. ”

“ Hold on to it and work the wheel round with your hands till a float projecting a little beyond its fellows comes opposite you. In this you’ll find a slit cut, ending in an eye-hole. Pass the rope, as it dangles, into this hole, and keep it in place by a turn of the iron button that’s fixed underneath the slit. Now step on to the broad float, never letting go the rope, and the weight of your body will turn the wheel, carrying you downward till a knot in the rope stops your descent.”
“What then, dad?”
“My son—you’ll see the place that for twenty years has held the secret of my fortune.” ”

“ The impact of one coming down throws the other up into the air some three or four feet. A rope is drawn above their heads like a clothes-line, and to this they cling as they go up in the air, in order to insure their equilibrium. ”

“ If they wish to capture an animal, they hurl one of the stones at it with singular address. By the peculiar art with which the ball is thrown, the rope makes a turn or two round the neck of the animal, which remains entangled, without the power of escaping. ”
