Here, too, was raw material organized: a fly-wheel, large enough to keep the knobbiest of asteroids revolving without a wabble; a cross-head, cross-tail, and piston-rod, to help a great sea-going steamer breast the waves; a light walking-beam, to whirl the paddles of a fast boat on the river; and other members of machines, only asking to be put together and vivified by steam and they would go at their work with a will.
He pointed out that, though the piston-rod was more or less straight, the piston-rod cross-head the thing that had been jammed sideways in the guides had been badly strained, and had cracked the lower end of the piston-rod.
The cross-head jammed sideways in the guides, and, in addition to putting further pressure on the already broken starboard supporting-column, cracked the port, or left-hand, supporting-column in two or three places.
These plates are set, one a little ahead of the other, to obtain successive opening or closing of the valves. When more steam is required the shield plate allows the proper pawl to fall into its notch in the cross-head and lift the valve from its seat. If less steam is wanted the shield-plate rises and allows the lower pawl to close the valve on the down stroke.
There the connecting-rod jammed. Meantime, the after-engine, being as yet unembarrassed, went on with its work, and in so doing brought round at its next revolution the crank of the forward engine, which smote the already jammed connecting-rod, bending it and therewith the piston-rod cross-head the big cross-piece that slides up and down so smoothly.
He was not engaged in the raising, and had only chosen to cross the tube, as being the nearest road from one tower to the other. An inquest was held on the following day, and a verdict of accidental death returned. No one actually engaged in the operation was injured, although Mr. Edwin Clark, who was superintending the operation, on the top of the cross-head, and his brother, Mr.
I'm going to get round to the other side, where I can reach the bell-rope, and signal the engineer to bring up the cross-head again." "Not walk around on this beam!" exclaimed Charlie, as his interest changed to genuine alarm, for he realized that such an attempt was a very different matter from standing quiet and holding on by the upright timber between them. "There's no other way," Mr.
He was going to forge and shrink a wrought-iron collar on the neck of the piston-rod where it joined the cross-head, and from the collar he would bolt a Y-shaped piece of iron whose lower arms should be bolted into the cross-head. If anything more were needed, they could use up the last of the boiler-plate. So the forges were lit again, and men burned their bodies, but hardly felt the pain.
The others stayed aboard and replaced piston, piston-rod, cylinder-cover, cross-head, and bolts, with the aid of the faithful donkey-engine. The cylinder-cover was hardly steam-proof, and the eye of science might have seen in the connecting-rod a flexure something like that of a Christmas-tree candle which has melted and been straightened by hand over a stove, but, as Mr.
This kind of attachment was found to be more convenient than the mode of passing the hawser through the ring of the buoy when the vessel was to be made fast. She had then only to be steered very close to the buoy, when the salvagee was laid hold of with a boat-hook, and the BITE of the hawser thrown over the cross-head.
