Spur gear

“ Gear Casing.—Push forward and remove receiver lock pin and unhook gear casing from gear case hinge pin.
Mainspring Group. To strip completely the parts assembled in gear casing, raise the gear stop with the point of a bullet, and allow mainspring to unwind. ”

“ By gripping the endless rope between grip wheels (see 1208) the small wheel can be thrown into gear to grip the rope by a lever, cam or screw.
c. Differential gear may be driven from a shaft by belts or gearing. See Sections 84 and 3.
d. Screw gear. Ditto.
e. Rack gear. Ditto.
f. Worm and wheel gear. Ditto.
g. Friction gear is usually driven as No. 1211.
1211. Where the barrel shaft has a slight horizontal movement, so that, by the lever, it can be forced into gear with the friction pinion to raise the load, or into the brake block to sustain the load or lower it. ”

“ Rope and spurs will be necessary. I prefer the Mexican grass rope with a brass honda to the rawhide riata, because I am used to it. I once used a linen rope with weighted honda that was soft and threw well. The spurs will be of good steel, of the cowboy pattern, with blunt rowels. The smaller spurs are not so easy to reach a small horse with, and are apt to overdo the matter when they do. The wide spur leathers are to protect the boot from chafing on the stirrups. ”

“ The imported gear cases are clumsy and heavy, and, being made mostly of metal, are apt to be noisy. The 1898 gear cases of American make are made of a combination of rubber, leather and metal, and are light, noiseless and graceful, and most of the leading makes of the chain cycles for the coming season are built with sufficient clearance to take a gear case. ”

“ The gear on the armature shaft should be as small, and that on the axle as large, as practicable. The intermediate gear should be of such a size that it will close the space between the small gear on the armature shaft and the large one on the axle. ”

“ The wheel is thrown into or out of gear, that is, made to bear on the rail of the chassis or relieved from it, by turning the axle with a wrench placed on the octagonal end. In the direction of the radii of the wheels, but inclined outwards, mortises are placed for the reception of the end of the iron handspikes, by acting on which while inserted the wheels are turned, and the carriage moved back and forth on the chassis. Ordinarily, when the wheels are thrown into gear, the carriage being back, it will run into battery of itself. ”

“ At each machine sat a human being working with hand, foot, and eye, watching the flashing needle, guarding the margin of the seams, jerking the cloth hither and thither quickly, accurately, watching the spool to see that the thread ran freely, oiling the gear with one hand while the other continued to push the garment rapidly under the needle, the whole body swaying, bending, twisting this way and that to keep time and pace with the work. ”

“ Attached to the trail are the trail spade, float trail handspike, trail handles and the lunette.
Elevating Gear.—The elevating gear is of double-screw type and consists of an inner and outer elevating screw, an elevating-gear bracket, an elevating bevel gear, two elevating bevel pinions, and two elevating crank shafts. The inner elevating screw is a steel screw, threaded with a right-hand thread. It is attached at its upper end by the elevating pin to the rear end of the rocker. ”

“ The rifle is to the right of the rider, lying in a central position along the centre of the machine. Not an inch of spare space is lost, as all the distance between the back and front wheel is taken up by a leather valise, which is divided into various parts, the upper portion of which carries a good supply of cartridge cases, and there is plenty of room below for the various travelling instruments required in case of accident to the cycle, and for all other necessaries. ”

“ Instead of breeches and gaiters, many men wear trousers of moleskin or other strong material.
Boots.—Shooting boots, strong, well–dubbed. In wet weather indiarubber soles are very slippery, but in dry weather, on rocks, they are perfect. Rubber–soled shoes should be carried on the wallets.
Spurs.—The Colonial fashion of wearing one spur only is not a bad one where mounted infantry work is to be done. The spur should be very short, so as not to trip you when on foot.
Coat.—Burberry kharki gabardine, carried by day rolled up on the pommel of the saddle. ”

“ When first leaving port, studding-sail gear is to be rove, all the running rigging to be examined, that which is unfit for use to be got down, and new rigging rove in its place; then the standing rigging is to be overhauled, replaced, and repaired, in a thousand different ways; and wherever any of the numberless ropes or the yards are chafing or wearing upon it, there “chafing gear,” as it is called, must be put on. This chafing gear consists of worming, parcelling, roundings, battens, and service of all kinds—both rope-yarns, spun-yarn, marline, and seizing-stuffs. ”

“ A leather stud should be sewn on the left boot, about 2-1/2 inches above the heel, on which stud the spur should rest, and thus be kept in its place without tight buckling. The spur found to be the most useful after the trial of many is a rowel spur of plated steel, about two inches to two and-a-half inches long, strong and light, hunting shape, and fastened with a strap and buckle, the foot-strap of plated steel chain. This chain foot-strap looks neater than a leather one, and does not become cut or worn out when on foot on rough or rocky ground. ”

“ Double wedge gear.
1495. Governor gear. The rope attached to the cage drives a governor acting on a brake or catch which is thrown into action if the cage gains excessive speed, used in Attwood Beaver’s Patent; American Elevator Co., &c.
1496. Rack and pawl gear.
1497. Cross grip lever gear.
1498. Safety hook to prevent accident from overwinding; the projecting horns A A strike the edges of the plate B, and throw the shackle C at top out of gear.
For hoist doors the best appliance is an ordinary spring lock opened only by a key, the doors being provided with springs to close them. ”

“ The sparking gears are driven by means of a gear formed on a sleeve which telescopes over the hub of the starboard drum, and has a bearing thereon, the end of the sleeve terminating in a ring which is fastened to the crank shaft. ”

“ After inserting bolt, rod, and charging handle, the charging handle is carried forward to extreme end of its stroke before gear casing is swung up into place and rack engaged.
4. The mainspring is wound up by engaging the rack and gear, disengaging the guard, and pulling back on the charging handle until the required tension is obtained. The gear is then disengaged, charging handle moved completely forward, gear re-engaged and guard pushed home.
5. To reduce tension of mainspring proceed as follows:—
Remove buttstock. ”

“ The white webbing belts, supporting the cartridge-box and bayonet-scabbard, were hung on pegs projecting from the wooden shelf. Shoes, "neatly blacked and dusted at all times," were aligned at the back of the floor, toes to the front. [68] Such books as were allowed were piled on the floor at the back end of the locker. All woollen uniforms, overcoats, rubber coats, etc., were to be hung on the hanging-pole. All white trousers, sheets, underclothing, collars, cuffs, gloves, etc., to be stored, each man's in his own locker. ”

“ By means of these it is possible to change the gear of the machine so as to have a high gear under favourable conditions and a low gear when mud, wind, or an ascent make travelling difficult. Although chain gearing is used in nearly every machine made, connecting rods, wheels, or bands are fitted instead to some machines. ”

“ In his knapsack were all the necessaries of a soldier—to wit, one pair of shoes and long gaiters of black cloth, shirts, socks, and mitts; a forage cap, brushes, black-ball, pipeclay, hair-ribbon, and leather. He had to carry a blanket and great-coat, a canteen of wood for water, and a canvas havresack for provisions was slung over the right shoulder; a pouch with sixty rounds of ball cartridge was over the left; add to these his musket, bayonet, belts, and grenadier cap, and the reader may believe that the poor volunteer felt life a burden before he saw the hill and spires of Portalegre. ”

“ As a large gear reduction is thus rendered possible on the back axle, it will readily be understood that the change-speed gear-box may be made considerably smaller than would be necessary for a bevel-driven live axle, where a large gear reduction is not permissible, both on account of its size and because such a gear would be very noisy in its working. ”

“ There is hinged to the frame in front of the breech-casing a curved plate, covering partially the grooved carrier, into which is formed a hopper or opening, through which the cartridges are fed to the gun from feed-cases. The frame which supports the gun is mounted upon the carriage used for the transportation of the gun.
“The operation of the gun is very simple. One man places a feed-case filled with cartridges into the hopper; another man turns the crank, which, by the agency of the gearing, revolves the main shaft, carrying with it the lock cylinder, carrier, barrels, and locks. ”

“ Had the object been to give the utmost possible trouble to the infantry-man, no better means could have been devised than inflicting on him the belts at present used, of all others the most easily sullied and troublesome to clean. Let a black patent leather belt and rifleman's cartridge-box be adopted as the regulation for the whole of the British service. Light to carry, convenient in form, and easy to clean, it is the perfection of infantry equipment. ”

“ In my case, the chain shirt being too big for me, I put it on over all my clothes, which caused it to bulge in a somewhat ungainly fashion. I discarded my trousers, however, retaining only my veldtschoons, having determined to go into battle with bare legs, in order to be the lighter for running, in case it became necessary to retire quickly. The mail coat, a spear, a shield, that I did not know how to use, a couple of tollas, a revolver, and a huge plume, which I pinned into the top of my shooting hat, in order to give a bloodthirsty finish to my appearance, completed my modest equipment. ”

“ We hoped not to need such emergency rations and, fortunately, never got to that stage in our subsequent adventures. Over and above the 20 lb. of food we estimated that each one would need to carry 10 lb. more in kit and equipment, the former comprising a spare pair of socks, a "woolly" and vest or something similar, and the latter a haversack and waterbottle, matches, knife, spoon and soap. In addition we carried a sail, about 40 feet of light rope, a light axe head, two canteens, a safety razor, housewife, nails and thread for repairing boots, maps, and compasses. ”

“ It is also pierced with a conical hole for the axle-arm; and to diminish wear and friction, it is lined with a box of brass or cast iron, called the nave-box. The spokes serve to transmit the pressure of the load to the rim of the wheel. In all artillery carriages there are seven felloes and fourteen spokes. The felloes are the wooden segments which form the rim, and are joined together at their ends by wooden pins, or dowels. The tire is a strong band of iron, shrunk tightly around the felloes, to hold them together, and protect the rim from wearing away by contact with the ground. ”

“ It simply presented the men who acted, clad in the outward garb, and bearing the tools and weapons of their day. The cut of a garment, the form of a helmet or halberd, a saddle or a semitar, a hoe or a hatchet, or the cut of the hair or the beard, may speak of the heart and soul, only, however, by distant hints. ”

“ What, then, would he require—that compact little kit of burglar tools, rolled in its leather jacket, that, unrolled slipped about his body like a close-fitting undervest? As well to take it anyway. He removed his coat and vest, took out the leather bundle from the safe, untied the thongs that bound it together, unrolled it, passed it around his body, life belt fashion, secured the thongs over his shoulders, and put on his coat and vest again. A revolver, a flashlight? He had both—at the Sanctuary, under the flooring—but there were duplicates here! ”

“ Gears was the name old wagoners applied to harness. The gears used on the team of the regular wagoner were of immense proportions. The back bands were fifteen and the hip straps ten inches wide, and heavy black housing covered the horses’ shoulders down to the bottom of the hames. The traces used were iron chains with short and thick links. It required a strong man to throw these heavy gears on the back of a big horse. Heavy and broad as they were, these gears were not out of proportion to the large fat horses of the old teams, and looked well on their broad and shining backs. ”

“ For my own part, being a handicraft, I marched under a weight sufficient to impede the free motions of a donkey; for besides my well-filled kit, there was the great-coat rolled on its top, my blanket and camp kettle, my haversack, stuffed full of leather for repairing the men's shoes, together with a hammer and other tools (the lapstone I took the liberty of flinging to the devil) , ship-biscuit and beef for three days. I also carried my canteen filled with water, my hatchet and [Pg 27] rifle, and eighty rounds of ball cartridge in my pouch ”

“ The trunnion-hoop is of wrought iron. The gun has, properly speaking, ribs instead of grooves, the grooves being cut in the projectiles. The twist is a constant one.
Vavasseur Gun and Carriage.
The gun-carriage possesses a peculiar recoil arrangement, consisting of a heavy screw-shaft traversing the middle of the slide and carrying at its forward end a wrought-iron friction-wheel with a metal strap worked by a lever, by which any desired amount of friction may be applied. Attached to the carriage is a sleeve or clutch grasping the screw-shaft. ”

“ The first thing that strikes us as we look at these men is their superb kit and outfit. From the broad cowboy hat, the neat uniform close fitting at the waist, down to their American shoes; from the saddles, bits, and bridles to the nose bags of the horses; from the guns, motors, and trucks down to the last shoe lace, the equipment is incomparably the best and most expensive of all that we have seen at the front. ”
