Running gear

“ The question of gearing is complicated by the fact that the frame of the car oscillates vertically with respect to the axles. Spur-wheels, worm-gear, friction gear, belts, multiple-band gear, and chain-gear are or have been used. ”

“ 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 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. ”

“ 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. ”

“ 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. ”

“ Improved gear and new machines were introduced in the woods; for accelerating yard movements of lumber, electric or gasoline-powered carriers came into use, performing the work of 36 horses and 18 teamsters at a saving of 60 per cent. ”

“ For example, in my governor gears their true running required that the bore should be absolutely correct, both in position and in direction. I had seen many gears bored. They were held in the jaws of a chuck and trued by marking their projecting side when running with a piece of chalk. It was evident that absolute truth could hardly ever be reached in this way, and the approximation to it depended wholly on the skill and pains of the workman. [32] Besides, much time was lost in setting each wheel. ”

“ GEAR (connected with “garb,” properly elegance, fashion, especially of dress, and with “gar,” to cause to do, only found in Scottish and northern dialects; the root of the word is seen in the Old Teut. garwjan, to make ready) , an outfit, applied to the wearing apparel of a person, or to the harness and trappings of a horse or any draft animal, as riding-gear, hunting-gear, &c.; also to household goods or stuff. The phrase “out of gear,” though now connected with the mechanical application of the word, was originally used to signify “out of harness” or condition, not ready to work, not fit. ”

“ Self-reversing gear, with one belt, two fast and one loose pulleys. The large spur wheel is driven from the bevil gear, and carries the weighted lever past the vertical position by a stop on the face-plate or disc, when it falls over and reverses the belt fork. ”

“ Equipments in Use.—Practically all nations have abandoned the simple wheeled carriage for machine-guns, or rather have adopted the tripod or table mounting, reserving the wheeled vehicle for the mere transport of the equipment. ”

“ 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. ”

“ Within a circular rampart, formed out of various articles of household gear,—three or four antique-looking spinning-wheels, a pair of churns, a few clumsy chairs, a large chest, together with a couple of small heavy waggons not yet placed upon the wheels,—were a few as lively recruits as any land desirous of population could wish to welcome. ”

“ To accurately divide off the pitch circle of a gear-wheel by hand, requires both patience and skilful manipulation, but it is time and trouble that well repays its cost, for in the accuracy of spaces lies the first requisite of a good gear-wheel. ”

“ The soldier hurled himself upon the aged peasant, felled him with one blow, sprang to one of the bicycles, started the engine, ran the machine a few yards and leapt into the saddle. With every jolt as the bicycle gained speed on the rough track his heart grew more elate. ”

“ When you put your tackle together you will make it far 147safer if you consider it as one apparatus or machine from hook to reel and if you let the rod top, or “tip,” be the weakest point of all, because by it you can best determine the strain upon the whole gear. ”

“ 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. ”

“ Men were stripping the gear. The engine-room showed a sort of orderly confusion. Mark sighed thankfully that it was the natural perversity of the strap, and no carelessness of his, that had caused the trouble. ”

“ The higher gears are useful for normal conditions or for riding with the wind blowing on the rider's back or down slopes when the gradient is not steep enough to let the machine run down quickly by its own weight. ”

“ Such tests prove the endurance of the motor cycle, and pave the way to its use in more profitable employments. Volunteer cycling corps often include a motor or two, which in active service would be most valuable for scouting purposes, especially if powerful enough to tow a light machine-gun. ”

“ 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. ”

“ There is a rush of men, the click of a bolt, a red fire-engine, spitting and swearing with the sparks flying from the furnace, is dragged out of its shelter. A huge brake, which holds supplementary horses, men, and hatchets, follows, and a hose-cart is the third on the list. ”

“ The recruit must learn how to raise the heavy machine by his own efforts, by means of a rope rove through a ring-bolt. We had an opportunity to see the recruits raising the machine together to get it off the wagon. The men are practised in leaping up when the vehicle is starting off at a great pace after the wheels are manned to give an impetus to the vehicle which carries such a burthen.
But the "rescue drill" is still more interesting, and this exhibited the strength and dexterity of the firemen in a surprising manner. ”

“ 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 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. ”

“ We left some of our less needful gear in charge of the headman, and then shouldering our guns, we set out for the mountain, a good ten mile walk, over bad roads, and the last three or four miles is stiff climbing most of the way. ”

“ 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. ”

“ Somehow I never could learn to change gears properly on a horse. He is always running in low when I'm in a hurry, or I step on the accelerator unintentionally but with disastrous effect, or else get to running along in high and can't work the brakes. ”

“ A change speed gear is a device that allows the gear ratio to be altered to suit the conditions of the road or the riding conditions prevailing at the time. A low gear ratio, one to two, for example, means that the rider is enabled to climb hills better but not faster; the power of the rider does not vary but the power strokes in pedalling are divided into a greater number of efforts in a given time. ”

“ The last mentioned drawback can be remedied apparently only by the adoption of a folding wheel, but, since the cyclist’s equipment cannot be secured on the machine, it is better in difficult country to push the wheels or to leave them behind under guard when necessary. ”

“ It seems probable that in time of action the mounted cyclist will be able to get within an easy distance of the field, dismount and detach his rifle in a couple of seconds, put his machine in a place of safety, and be on the scene of action quicker than he could by any other means. ”

“ To cross-lift a gun, or carriage, is to move it in a direction nearly perpendicular to its axis. Heavy guns, mounted, or dismounted, require a long lever, and a fulcrum, for cross-lifting. Guns of medium weight may be cross-lifted by means of handspikes. ”

“ A rifle on the hillside cracked with a spiteful suddenness, and in a huddled heap the driver dropped forward, liberating the reins from his hands, The terrified horses threw themselves into the traces, the coach gave a leap ahead, and, driverless and aimless on the mountain-shelf, the race was on. ”

“ He likens his gear, in working, to the familiar breast drill, except that the drill has its teeth somewhat bevelled. If simplicity coupled with great strength and rigidity of frame, together with cheap construction and smooth and quiet action, are attained by this gear, as expected, it will evidently score a point among chainless models; but that straight-cut teeth can interact successfully at all with gears set at right angles or nearly so is contrary to all ideas heretofore, and in the lack of a model for examination we must forbear any opinion. ”

“ The motor-ambulances move here, there and everywhere over the clayey fields, where the wheels of the ammunition wagons have drawn mighty furrows, like those that peaceful toil once made here. One hardly sees the faces of these men. ”

“ Enemies in ambush, the peril of fire, and the guarding of treasure make exciting times for the Motor Rangers—yet there is a strong flavor of fun and freedom, with a typical Western mountaineer for spice. ”

“ What a mass of carts, drays, buggies, wheelbarrows, handbarrows, and many queer makeshifts for carrying goods—the strangest of all a large barrel set on an axle, and dragged or shoved by means of two long handles, the proud possessor's belongings turning round and round inside until they must surely be churned into a most confusing jumble. ”

“ 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. ”

“ Notwithstanding this facility for water-power, we witnessed the stupendous folly of a small cotton-gin with eighteen saws in operation by the force of a treadmill, worked by the leg-power of men; and a screw was also seen at the same place worked by manual force of these bipeds.
In this apparatus there is a huge upright wheel of fifteen feet diameter, in which a man is constantly walking, and yet not advancing ”

“ Mention other parts of a field-carriage.
Cap-squares, ear-plates, trunnion-plates, under-strap, elevating screw, wheel guard plate, axle-tree, trail-plate, trail-handles, prolong-hooks, pointing-rings, washer-hooks, lock-chain, sponge-chain, sponge and rammer stop, bolts, rings, bands, hooks, keys, straps, nuts, and nails. [Pg 96]
19. What is the limber?
It consists of a similar axle-body, axle, and two wheels, and on these rests a frame-work to receive the tongue. On top of the whole is an ammunition box, the top of which forms a seat for three cannoneers. ”

“ The load of the gun and the peak load put on the carriage when the gun is fired are so great that it requires four trucks of 8 wheels each, 32 car wheels in all, to distribute the load safely over ordinary standard-gauge track. ”

“ All the wheels of the going part, except the great wheel, are set in a separate frame called the movement frame, which is complete in itself, and light enough to take off and carry away entire, so that any cleaning or repairs required in the most delicate part of the work can be done in the clock factory, and the great wheel, barrel, and rope need never be disturbed at all. ”
