Page 168 - ... with a hook at one end and an eye at the other ; links furnished with eyes are joined by links furnished with hooks, or by keys, pins and wedges.
Page 12 - ... spokes are subject, is from the lateral thrust brought to bear upon the nave when one wheel becomes lower than the other by dipping into a rut, &c. In order, therefore, to place them in a better position to resist this thrust, the wheel is " dished," or formed into a kind of dome ; and just as the dome or arch is strong, from its form, to resist pressure upon the crown, tending to crush it in, so is the wheel made strong by the dish to resist the lateral thrust tending to force the nave outwards....
Page 12 - These facts accord with those observed in the case of the pita that grew continuously, not intermittently, to maturity from the initial and less advanced stages of previous exposures to the acid. The stepped figure seems, then, to show that the formation of pits may (though not always) take place spasmodically...
Page 146 - The frustra are pressed together, as desired, by means of a nut Q, outside of which a locking nut R is placed. A loading stage is formed between the sides at the centre by baulks supported on angle-iron frames. In this pattern the operation of loading is much easier than in the first pattern, being performed under instead of over the counterweight. The projectile being placed upon the loading stage is hoisted to the muzzle by...
Page 137 - In fact the elevator may be regarded as a lever of the first order, the gun at one extremity and the weight at the other ; and here it is to be noticed, first, that the fulcrum on which the elevator rests is not fixed, but movable or changing, whereby any jar or concussion to the parts on discharge is avoided, at least in a horizontal direction ; second, still further to...
Page 140 - The counterweight boxes (three, two side and one centre) are bolted between the sides in such a manner that when the gun is raised to the firing position they lie between the sides of the platform. These boxes are packed with pieces of cast iron and wood of sufficient weight to raise the gun from the loading to the firing position without a dead point. In the upper part of the elevator are metal-benched holes to receive the main shaft which connects the carriage to it.
Page 140 - The cross stay is of girder iron, and is bolted beneath the sides 9^' from the front. The pivot stay is a diagonal stay of plate iron ; its centre, to which a pivot socket is attached, is bolted under the centre of the cross stay and its arms under the sides. The flanged feet are bolted beneath the sides, those in front projecting outwards ; two have metal bearings for the axles of the trucks. The latter are of wrought iron, 16'' in diameter, and their axles are of steel.
Page 108 - ... for the ironpointed lever by which it is turned; when thus moved it turns the spindle, as it has feathers on it, which enter slots in the latter, and the spindle by its pinion moves the arc. The jamming lever screws upon the spindle outside the capstan head, so that when tightened upon the latter it clamps the pinion. The thread of the spindle...
Page 84 - Upon the near side a small outrigger is fixed to the splinter bar to take a swingletree for double draught, and upon the points of the shafts there are eye plates to receive the trace hooks of a leading horse or drag ropes. The cart is also fitted with staples underneath the shafts to take slats for man draught. Props are attached to the hind part of the cart as well as to the shafts. A canvass cover and lashing rope are issued with the cart, and a web girth attached to the shafts.
