Jib sheet

“ If a sudden squall strikes the boat, let go the jib-sheet, and it will luff up quickly. When running before the wind the jib may be used as a spinnaker (see sketch of skiff) by placing the sails "wing-an'-wing," and if there is not enough wind to hold the jib out, a light pole or an oar may be used for that purpose. If the racing rules permit, a pole may be set over the side abreast of the mast, and the jib rigged as a regular spinnaker.
The crew should be disposed, when possible, so that the boat will set deeper in the stern than in the bow ”

“ Many combinations are made with the jib. There seems to be about only one common way of rigging a jib for a small boat. A pretty clear idea may be gained from the sketch (Plate I) . As may be seen, no stay is used, the sail usually being bound with a rope, which gives it sufficient strength; no halyard is used, either the jib being lashed to the mast, and lowered and hoisted when it is stepped or unstepped. The lower edge is laced to a boom, which is secured to the bow with a lashing about four inches long, a third of its length projecting. The sheet rope is fastened to the inner extremity. ”

“ If by any mischance the mainsheet becomes jammed do not hesitate, but cut it. A sharp knife in such an emergency has often saved life when an upset has seemed inevitable through the boat being nearly on her beam ends. If you are sailing in a jib and mainsail craft, and the squall has a good deal of weight in it, let fly the jib sheet and let the boat come up in the wind, at the same time lowering away the mainsail and taking care to spill it as it comes down. ”

“ The jib has two sheets, one on either side of the mast, one of which is hauled in and the other slackened out, according to the tack the vessel is on.
When the jibs are small the sheets require no purchase, but each should lead either through a single block on the gunwale or a comb cleat (Fig. 35) on the deck. It is important that this fairlead be exactly in the right spot, for on this depends whether the jib stands flatly or becomes a loose bag. The right spot can only be determined by experiment. ”

“ The jib is a triangle of 3 feet hoist and 3 feet foot, the fore-leach fast by a loop, passing under the painter and over the stem; the head is fixed by a loop over the mast-head, and under the flagstaff button. Thus the jib can be struck while the canoeist remains in the boat, by pushing off these two loops with his paddle. To set the jib, it is best to land. This is much more generally convenient than to have jib-tackle on the mast. (I have now discarded the jib entirely.) The sails are of calico, without any seam. ”

“ I suppose 199you all know what sheets are, and have got rid of the lubberly idea that the sails are called by this name."
"I think we all know that the sheets are ropes," added Ash.
"The jib is made fast at all points except at the clew, or at the after-clew, as some would say. By the sheets, the jib is trimmed so as to sail on the wind or otherwise. In small craft, these sheets usually lead aft, to the standing-room, or cockpit as it is sometimes called, so as to be within reach of the person sailing the boat. If there is a flying-jib, it is handled in precisely the same way." ”

“ A vessel is often known by the cut of the JIB sail; hence the popular phrase, “to know a man by the cut of his JIB.”
Jibb, the tongue.—Gipsy and Hindoo. (Tramps’ term.) Thence extended to mean language.
Jiffy, “in a JIFFY,” in a moment.
Jigger, a door; “dub the JIGGER,” shut the door. Ancient cant, GYGER. In billiards, the bridge or rest is often termed the JIGGER. Also, the curtain of a theatre. Jigger has many meanings, the word being applied to any small mechanical contrivance. Printers use the word for a little machine which guides the eye when copy is minute. ”

“ Fig. 119 Jibs.—For the fixing of the gear a jib (fig. 119) is sufficient to carry a fixed pulley. A jib is a single pole attached horizontally to the standards or ledgers above the platform upon which it is126 intended to deposit the material. It should project slightly more than half the width of the load to be hoisted, usually from 18 inches to 2 feet.
Fig. 120
It is useful at times to have a pulley block fixed over the work in hand, especially for fixing purposes. ”

“ If the mainsheet is well handled the mainsail never shakes. As it loses the wind on one side it catches it on the other, the jib being kept slightly aback until the boat's head is well off the wind. It is no joke to handle the jibsheets of an 8- or 10-ton boat. ”

“ Cranes of this type and strength are frequently found necessary for the inside work of goods-sheds, where packages of considerable weight have to be handled. A very similar class of jib-crane is constantly made for lifting weights of five or ten tons or more, the different parts being made stronger and heavier to correspond to the weights to be raised. ”

“ Large vessels often carry several jibs; as, inner jib; outer jib; flying jib; etc.
2. (Mach.) The projecting arm of a crane, from which the load is suspended.
Jib boom (Naut.) , a spar or boom which serves as an extension of the bowsprit. It is sometimes extended by another spar called the flying jib boom. [Written also gib boom.] -- Jib crane (Mach.) , a crane having a horizontal jib on which a trolley moves, bearing the load. -- Jib door (Arch.) , a door made flush with the wall, without dressings or moldings; a disguised door. -- Jib header (Naut.) , a gaff-topsail, shaped like a jib ”

“ But on the fore we have the head-sails. The extreme outer one we cannot see; it comes down from the fore-royal and ends half-way down, being a mere "kite;" it is called the "jib topsail." The outer one we can see is the "flying-jib," on the flying-jibboom. Then come the "outer jib" and the "inner jib" and the "foretopmast staysail."
The "trysails" are gaff or jib-headed sails sometimes carried on the fore and main, as the spanker is carried on the mizzen. ”

“ The use of a jib presents many new problems in sailing, and will necessitate some thought and study on the part of a boy whose experience has been confined to the handling of a cat-boat. In the jib-and-mainsail rig there are two opposite forces at work. The mainsail, as in the cat-boat, throws the boat's head in the wind, only this is more pronounced, as the mast is stepped further aft. ”

“ The crane will stand the greatest strain when the jib is most upright, and, reversely, less strain as it approaches the horizontal. It is a good rule, and one which works for safety, not to allow the top end of the jib to reach a lower level than the top of the mast, whatever the weight of the load carried may be. ”

“ The jib-header can be used in strong winds. When out at sea in really bad weather, it is often of great advantage to set the jib-header over a reefed mainsail, for the wind still fills it, and the steerage way is preserved while the reefed mainsail is becalmed in the trough of the sea. By means of a jackyard, which extends the foot of the sail beyond the end of the main gaff, the area of either a jib-header or a yard topsail can be increased. ”

“ A jib is of little use as a sail. It is apt to get aback in sudden turns. Besides, you must land either to set it or to take in its outhaul, so as to be quite snug. But the jib does well to tie on the shoulders when they are turned to a fierce sun. The boom should be attached by a brass shackle, so that when "topped" or folded its end closes on the top of the mast. The sails (with the boom and yard) should be rolled up round the mast compactly, to be stowed away forward, so that the end of the mast resting on the stretcher will keep the roll of sails out of the wet. ”

“ Jib—foot, eleven inches; hoist, sixteen inches—on the stay, twenty and one-quarter inches. The jib carries a boom, and the main-sail a gaff and boom. The material used for the sails is light muslin with hemmed edges.
Take a long chalk-line or heavy cord, and stretch at right angles to the direction of the wind. If the wind is from the north, the cord must reach east and west. Each extremity of the cord must be the same height from the ground, and can be attached from tree to tree, or from an upper-story window to a house near by. ”

“ If the nib is then not wide enough it may be cut again; if too wide, the sides may be pared down.
Cut very little at a time off the tip of the nib; a heavy cut is apt to force the pen out of shape and spoil the edge of the nib.
VI. The nib should then be examined with the magnifying glass. Hold the pen, back down, over a sheet of white paper, and see that the ends of the two half-nibs are in the same straight line a–b (fig. 30) .
The nib should have an oblique chisel-shaped tip, very sharply cut (fig. 31) . ”

“ For instance, if holes were to be bored in the casting for a jig templet which had simply been planed on the top and bottom, the casting could be bolted to a finished plate having square edges and the latter be set in the different positions required, by means of size blocks. Comparatively large jig plates are sometimes located for boring in this way and the milling machine is often used instead of a lathe. ”

“ He did so, and we spread out on his table drawing after drawing, which Jimmy explained in his slow, methodical way.
"We have also the formulæ and close calculations on a separate sheet which no one but I could understand," he said in conclusion. "They, of course, are the key to the entire set of plans. One without the other would be so incomplete as to be almost useless. They were purposely compiled in that manner. Let me see. Those sheets are—"
He began to move the plans about, sheet by sheet. ”

“ At this moment the telephone bell rang, and the Imp had to go see what was wanted.
"Excuse me for a moment, Jimmieboy," he said, as he started to leave the room. "I've got to send a message for somebody. I'll turn on one of the picture-books, so that while I am gone you will have something to look at."
The Imp then fastened a wire to the battery, turned on the current, and directing Jimmieboy's attention to the sheet of white canvas at the end of the library, left the room. ”

“ It is possible that sheets exist with the narrow spaced lines of perforation on the left side. We have searched in vain for such varieties, but they may exist. A sheet inverted when placed on the left side of the machine would shew the top margin perforated through, and narrow spaced perforation to left; while a sheet inserted top first on the right hand side would leave the top margin blank and the bottom one perforated through, and the narrow spaced perforation to left. ”

“ Value of Jigs and Fixtures.—The use of jigs, fixtures, and other labor-saving devices is an important factor in illustrating industrial and practical applications in the school shop. It is advisable to let each group of boys work out its own jig or fixture for the particular job they have on hand.
The three most common forms of jigs are cutting jigs, boring jigs, and assembling jigs. The important reasons for the use of such devices are: (1) They illustrate the speed of output in shop work. (2) They give the student a good idea of machine operation. ”

“ Reaching or going free you work the mainsheet and jibsheet alternately as best you can. All the boats have large open wells, the jibsheets lead aft through a couple of blocks shackled to the clew of the sail, with the standing part fast to eyes on each plankway, and leading blocks further aft. Thus there is just sufficient purchase to enable a strong man to control the jibsheet of a 10-ton boat. In sailing these boats there is no making the jibsheet fast if you wish to get the best speed out of the vessel. ”

“ The unconnected things centered in the singular behavior of the big man humped on the right-hand box. On the new card the "Flyer" made few stops and was practically given the right of road. Station after station the signals stood at "Clear"; each an unwinking eye of white with the red below it. Gifford, swinging rhythmically back and forth between tender and fire door, saw Jebb crouch and grip throttle and air-brake lever as each pair of signals sprang out of the darkness ahead ”

“ A "Pacific type" one-hundred-and-ten-ton compound, pulling a heavy train uphill on a quick card, does not give its fireman much time for reflective side issues. None the less, on this night of velvety skies and spitting raindrops, Gifford, Jebb's understudy, saw things not connected with his proper business of keeping the steam-gauge index at two hundred pounds pressure. ”

“ At first the stamps were perforated by a single line machine gauging 14. A single line machine, as its name implies, simply makes a single long row of holes in one direction—
In the present case, where the sheets were so small, the row is much longer than necessary, so in the sheets it extends through the margins on all sides, as in plate II.
[pg 29]
The horizontal rows may be perforated first (one row at a time) , and then the sheet is turned sideways and the vertical divisions are similarly perforated. ”

“ The sail is nine feet and six inches on the mast, six feet on the gaff, thirteen feet on the boom, and fifteen feet on the leach. The jib, also of twilled cotton, is eleven feet and six inches on the forestay, eight feet across the foot, and eight feet and six inches on the leach. The blocks can be of galvanized iron but patent sheave-wood blocks are preferable.
For the halyards Manila-rope three-eighths of an inch in diameter will be the right size, and a half-inch anchor-rope will be stout enough, since a catamaran does not tug as heavily on an anchor as does a boat. ”

“ That's Jib's real name. 'Jibbeway Pottoway'—that's the whole of it."
"Oh, oh!" cried Heavy, with her hand to her face. "It makes my jaw ache to even try to say it."
"What is he?" asked Madge, curiously.
"Injun," returned the Western girl, laconically. "Or, part Injun. He comes from 'way up Canada way. ”
