The paper "feed" is shown at the end of the press-lever, and consists of a push "dog," or pawl, which operates to urge the paper forward as the press-lever descends. The worm-gear which appears in the diagram on the shaft, near the toothed wheel, forms part of the unison stop above referred to, but this device is not shown in full, in order to avoid unnecessary complications of the drawing.
"From my experiments on the telephone I knew of the power of a diaphragm to take up sound vibrations, as I had made a little toy which, when you recited loudly in the funnel, would work a pawl connected to the diaphragm; and this engaging a ratchet-wheel served to give continuous rotation to a pulley. This pulley was connected by a cord to a little paper toy representing a man sawing wood.
"Tail on to the handles, my bullies, tail on and heave. Heave, and raise the dead!" shouted the man Mike, who had been one of the lucky five to escape capture by the savages. They got their first pawl easily enough, then another, and another, by which time the hawser was once more as taut as a bar.
It was Tom's hobby, and he delighted in nothing so much as tinkering with machines, from lawn-mowers to steam engines. Tom took hold of the handle, which Eradicate gladly relinquished to him, and his trained touch told him at once what was the trouble. "Some one has had the wheels off and put them on wrong, Rad," he said. "The ratchet and pawl are reversed.
K, lever and weight lifted by electro-magnet, E. A, open contact completed by pendulum each swing. B, battery. R, ratchet wheel and pawl. M, lever fixed at top. At the recent meeting of the Institution of Mechanical Engineers, Dublin, Mr. Davey, of Leeds, spoke of synchronizing mechanisms. He had occupied some of his spare time in attempting to synchronize clocks from a standard clock.
"Yes, you told me not to come, but you wanted me to come all the time. I know you did. You wanted songs, you wanted all the songs, and you had the ropes off the pawl before I had time to change my mind." "You should go home now," said the seaman anxiously. "Here is our young fellow, and he will walk up to the town with you."
If screwed out too far, the valve-stem becomes too long and the pawl in descending will, after the valve is seated, continue downward until it has broken something. If screwed in, the cross-head will be too low for the upper pawl to engage and the valve will not be opened. This second condition is not dangerous, but should be corrected.
We're very busy workin' at tryin' to mend this ole clock for you all." "Clever," said Jimmy, admiringly. "Mendin' the clock. Clever!" "William!" groaned his mother, "you've ruined the clock. What will your father say?" "Well, the cog-wheels was wrong," said William doggedly. "See? An' this ratchet-wheel isn't on the pawl prop'ly not like what this book says it ought to be.
The men strained at the bars until it seemed as though they would burst their very sinews; another reluctant click or two of the pawl showed that something was at length yielding; and then, first with a slow jerky motion which quickened rapidly, and ended in a mighty surge as the men drove the capstan irresistibly round, the bows of the schooner swerved to seaward, the vessel herself righted, hung for a moment, and then glided off the tail of the bank, finally swinging to her anchor, afloat once more.
Yo, heave, hearty, ho! and, in time with the song, by the force of twenty strong arms, the windlass came slowly round, pawl after pawl, and the weather clew of the sail was brought down to the water-ways.
