He worked on propeller shafts.
The shaft horse swayed from side to side, moving his ears as if asking: "Isn't it time to begin now?"
The breaking short of the shaft of the assegai when the weapon was used at close quarters was already a common practice among the Ama-Zulu, but Chaka had the shaft of the assegais made short, and their blades longer and heavier, so that they could be used for cutting or piercing.
Opposite Victoria dock is another ventilation shaft for the tunnels under the river.
The shaft horse swung steadily beneath the bow over its head, with no thought of slackening pace and ready to put on speed when required.
All tin, except a small quantity produced by the shaft furnace process from exceptionally pure stream tin ore, requires refining by liquation and "boiling" before it is ready for the market.
If the workable areas are poor, and appear only at long intervals along the outcrop, the chances of discovering richer areas by a shaft are very small.
A frame of wood or steel, erected at the shaft mouth, and rarely employed except for deep shafts of small cross-section or when the mine cars (tubs) are small, as in many parts of Europe.
A shaft of brilliant sunlight fell through the dusty layers of a horse chestnut tree, landing on the velvet vows of her shoes.
When he came to himself he was sitting on the ground leaning on his hands; the ammunition wagons he had been approaching no longer existed, only charred green boards and rags littered the scorched grass, and a horse, dangling fragments of its shaft behind it, galloped past, while another horse lay, like Pierre, on the ground, uttering prolonged and piercing cries.
"Now maybe you'll pay attention," he said and threw the shaft of the arrow.
On the same shaft with P is fixed a brake-wheel furnished with a powerful brake B, by the proper manipulation of which the speed of paying out is regulated, the pull on the cable being at the same time observed by means of D.
The cross-section of the cars was made to conform approximately to the section of the tunnel, the idea being that each train would act like a piston in a cylinder, expelling in front of it a column of air, to be forced up the station shaft next ahead of the train, and sucking down a similar column through the station shaft just behind.
The shaft-graves in the Mycenae circle are also a late type, paralleled in the later Cnossian cemetery.
1-2 in Crete, the shaft-graves in the Mycenae circle, the Vaphio tomb, &c., to the 16th and 15th centuries B.C., and Period III.
The campanile is usually a plain brick shaft with shallow pilasters running up the faces.
It is the centre of an important gold-field, the reefs of which improve at the lower depths, the deepest shaft on the field being 2558 ft.
From the girdle hung the single-edged missile axe or francisca, the scramasax or short knife, a poniard and such articles of toilet as scissors, a comb (of wood or bone), &c. The Franks also used a weapon called the framea (an iron lance set firmly in a wooden shaft), and bows and arrows.
Since the mineral occurs in definite veins, a more satisfactory and economical method of working would be that adopted in metalliferous mines, with a vertical shaft, cross-cuts, and levels running along the strike of the vein: the mica could then be extracted by overhead stopping, and the waste material used for filling up the worked-out excavations.
The shaft, resting upon arches supported by four cast iron columns about 9 ft.
Either to the simple lateral tail feathers with a few rami only, developed only on one side of the shaft and of uniform metallic coloration - or to the simple contour feathers of small size, with the usual symmetrical series of numerous rami right and left of the shaft and no remarkable colouring.
A central shaft descended 35 ft.
To the west of the main shaft were three square pits with horses and their harness, and by them two pits with men's skeletons.
Either in the shaft furnace or the reverberatory; the former is the better suited to stream tin, the latter to lode tin, but either ore can be smelted in either way, although reverberatory practice yields a purer metal.
Shaft furnace smelting is confined to those parts of the world where charcoal can still be obtained in large quantities at moderate prices.
The furnace consists of a shaft, circular (or more rarely rectangular) in plan, into which alternate layers of fuel and ore are charged, an air blast being generally injected near to the bottom of the furnace through one or more tuyeres.
The genus Machaeropterus, consisting of four species, is very remarkable for the extraordinary form of some of the secondary wingfeathers in the males, in which the shaft is thickened and the webs changed in shape, as described and illustrated by P. L.
If the outcrop of the vein or bed is accessible the shaft may be inclined and sunk to follow the deposit.
This is in general a cheaper and quicker method of development for inclined deposits than by a vertical shaft, and it has the added advantage that much information as to the character of the deposit is obtained as the shaft is sunk.
Of the drum depend on the hoisting speed desired and the depth of shaft or length of rope to be wound.
If, for a twocompartment shaft, a pair of drums (or a single wide drum) be keyed to the engine shaft, with the ropes wound in opposite directions, the hoisting is " in balance," that is, the cages and cars counterbalance each other, so that the engine has to raise only the useful load of mineral, plus the rope.
In the case of very thick beds and mass deposits the main shaft or tunnel will preferably be located in the foot-wall.
I and 2 illustrate the development of a metal-vein by two adits, two inclined shafts in the lode, and by a deep vertical shaft connected with the lode by horizontal cross cuts.
This is similar to shaft hoisting, except that the grades are often quite flat.
In geared hoists the drums. are on a separate shaft, driven from the crank-shaft by tooth or friction gearing, and make one revolution for, say, 4 or 5 double strokes.
Independent drums, on the contrary, are loose upon their shaft, and are thrown on or off by tooth or friction clutches.
The crook is usually richly ornamented, and is divided from the shaft by a boss; the shaft is commonly separated into sections by rings, so that it can be taken to pieces.
In the Public Square is a soldiers' and sailors' monument consisting of a granite shaft rising from a memorial room to a height of 125 ft., and surmounted with a figure of Liberty; in the same park, also, is a bronze statue of Moses Cleaveland, the founder of the city.
To render the elongation evident, another wire is attached to its centre S2, this last having a thread fixed to its middle of which the other end is twisted round the shaft of an index needle or in some way connected to it through a multiplying gear.
In diameter, passing from the bull-wheel shaft over a grooved wheel known as the crown-pulley, at the summit of the derrick.
Above the shaft comes the arcaded bell-chamber, frequently built of Istrian stone; and above that again the attic, either round or square or octagonal, carrying either a cone or a pyramid or a cupola, sometimes surmounted by a cross or a gilded angel which serves as a weathercock.
The famous Venetian pozzi, or wells for storing rain-water from the roofs and streets, consisted of a closed basin with a water-tight stratum of clay at the bottom, upon which a slab of stone was laid; a brick shaft of radiating bricks laid in a permeable jointing material of clay and sand was then built.
