In the first place it is obvious that if a ratchet runs freely in one direction and only catches on the tooth of the spur-wheel when it is drawn in the other, the power developed and used is concentrated on one stroke, when it might, with greater advantage, be divided between the two; and in the second place the shock occasioned by the striking of the ratchet against the tooth when it just misses catching one of the teeth and is then forced along the whole length of the tooth gathering energy as it goes, must add greatly to the wear and tear of the machinery and to the unevenness of the running.
By this plan, however, the oil is not well supplied at slow speeds, as the drops fall before the wires are in proper position for feeding the journal. Another lubricator consists of a cock or plug inserted in the neck of the oil cup, and set in revolution by a pendulum and ratchet wheel, or any other means.
His eyes were moist with righteous ardour. The cutlery reposed in a green-lined basket. She had doffed the apron and hung it behind the scullery door. With all the delicious curves of her figure newly revealed, she was reaching the alarm-clock down from the mantelpiece, and then she was winding it up. The ratchet of the wheel clacked, and the hurried ticking was loud.
I could hear my thin, aspiring voice reaching out over that paralysed audience with: Though my scarred and veteran legions Bear their eagles high no more; And my wrecked and scattered galleys Strew dark Actium's fatal shore. My tongue seemed frozen, or some kind of a ratchet at the base of it had got out of order. For a moment a moment can be the little sister of eternity I could say nothing.
You'd make a wooden Indian nervous!" There was silence for an instant, then a curious gnawing sound punctuated with quick, low, metallic rasps as of a ratchet at work and upon Jimmie Dale for a moment came stunned dismay. Time, the one factor upon which he had depended, was lost to him; Clarie Archman and Gentleman Laroque were already at work in there in that room beyond.
Other similar designs are known, by which the whole of the after deck can be pushed over from the stern by a ratchet arrangement, with air-tanks below to buoy it up: it seems to be a practical suggestion. One point where the Titanic management failed lamentably was to provide a properly trained crew to each lifeboat. The rowing was in most cases execrable.
The rings must obviously be fitted over a boss upon the back of the valve; and between the rings, which are of brass, a gasket ring is interposed to compensate by its compressibility for any irregularity of pressure, and each of the bolts is provided with a ratchet collar to prevent it from turning back, so that the engineer, in tightening these bolts, will have no difficulty in tightening them equally, if he counts the number of clicks made by the ratchet.
On the side of the clock case was a contact maker, which closed the circuit by the pin on the ratchet wheel, R, once every minute. The weight was lifted by the electric current, and by its fall gave an impulse to the pendulum. The pendulum was a free swinging pendulum for 59 sec., and the increase of the arc could scarcely be detected. By JOHN McCRAE, of Dundee.
By no means discouraged, they went back to the end; and this time, by progressing more slowly, the window was reached, and, to their great delight, Don found that it was fastened inside, opening outwards by means of a couple of hinges at the highest end, and provided with a ratchet, to keep it open to any distance required. "Can you bear me if I try to open it, Jem?" "Can I? Ah!"
The two young men went on up the stair. As their feet were approaching the sixth step, a sudden word came from the Penman like a bolt from his bow. "Halt!" he cried, and they heard the gur-r-r-r of his steel ratchet. Sholto smiled, for he knew the nature of the man. "It is I, your captain," he said. "You have done your duty well, Andro the Penman. Now get down to your dinner.
