The rectilinear motion of the piston-rod was thus converted into rotary motion. Mr. Miller was pleased with the action of the ratchet-wheel contrivance, and gave Symington an order to make a pair of engines of that construction. They were to be used on a small pleasure-boat on Dalswinton Lake.
Upon it was mounted a broad ratchet-wheel with a crank, while into the teeth of the wheel there played a stout, elastic slab of wood. The box would be placed on the table where the snorer was sleeping and the crank turned rapidly. The racket thus produced was something terrible, and the sleeper would jump up as though a typhoon had struck the laboratory.
It consists of a tympanum or drum, having a stylus attached as in the phonograph. When the tympanum vibrates under the influence of the voice, the stylus acts as a pawl and turns a ratchet-wheel.
He was a millionaire-baiter by nature and a pessimist by trade. Kenwitz would assure you in one breath that money was but evil and corruption, and that your brand-new watch needed cleaning and a new ratchet-wheel. He conducted Kinsolving southward out of the square and into ragged, poverty-haunted Varick Street.
"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.
A rotary motion of the shaft is useless here, as the click, F, acts in an oblique position upon the ratchet-wheel, O, and pushes it by reason of the to and fro motion of the screw. The name of Dr.
Thus the spring months will be the great time of the formation of ice, and also of the raising of the temperature from some degrees below freezing to the more temperate register at which I have generally found it, viz., rather above than below 32°. Professor Tyndall very properly likens the external atmosphere to a ratchet-wheel, from its property of allowing the passage of hot rays down to the surface of the earth, and resisting their return: it may equally be so described on other grounds, inasmuch as the cold and heavy atmosphere will sink in the winter into the pits which lead to glacières, and will refuse to be altogether displaced in summer by anything short of solar radiation.
Because that is the attitude of mind of the correct human person in such a case made and provided. That is, if an inevitable automatic action can be called an attitude of mind. Is rotation on its axis an attitude of a wheel's mind? To be sure, though, a wheel may turn either of two ways. A ratchet-wheel is needed for this metaphor.
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.
John Bull would look with sovereign contempt, or downright despair, according to the state of his stomach, on the thing called a roast in Rome. There it is seldom seen beyond the size of a beef-steak. Much small fry is roasted with a ratchet-wheel and spit. This is wound up with a weight, and revolves over the fire, which is strewed upon the hearth.
