It consisted of two dials mounted separately, each revolved by an electromagnet, so that the desired figures were brought to an aperture in the case enclosing the apparatus, as in the Laws system. Each shaft with its dial was provided with two ratchet wheels, one the reverse of the other.
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.
The third cause which catches hold, like a ratchet wheel in machinery, from time to time producing a complete standstill, is the greater strength of the defensive form.
Then his back raised up the hinged skylight higher and higher, till, holding on to the cross-bar with one hand, and the ratchet fastening with the other, he thrust up and up, till the skylight was perpendicular, and he paused, panting with the exertion. "All right, Mas' Don; I've got the rope. Now lower it down gently, till it lies flat on the slope. That's the way; steady! Steady!"
"There, there!" he said, trying to poke the more distant potatoes toward her with his cane. He could not himself stoop; or, if he did, he could only sit erect again after the method of a ratchet wheel. "I won't do so again, Prudence. I be an onthoughtful critter, if ever there was one." Prudence had recovered the last potato.
When the final sheet came out with a whirring rasp of the ratchet, he suddenly remembered that he had promised Miss Van Brock to dine with her. It was too late for the dinner, but not too late to go and apologize, and he did the thing that he could, stopping at his rooms on the way to dress while his cab-driver waited.
A ratchet wheel is fixed upon a little shaft which passes through the side of the oil cup, and is put into slow revolution by a pendulum attached to its outside and in revolving it lifts up little buckets of oil and empties them down a funnel upon the centre of the bearing.
An armature is arranged so that when a thread is broken or a sliver or a strand of roving, the armature drops into a ratchet wheel; this ratchet wheel is made to revolve by the belt, and whenever it is impeded or stopped in its course it acts upon mechanism which throws the driving belt of the machine upon the loose pulley.
The brakes will not hold them. If we are going to meet anything we might as well meet it properly," answered Phil calmly, whereupon he kicked the ratchet loose and spun the brake wheel about. The car seemed to take a sudden leap forward. Just then there came a rift in the clouds. "Look!" cried Billy. Phil leaned over the rail, peering into the mist.
He reeled like a drunken man and dropped the gun on the floor with an oath. "Beaten again," he muttered. "Forgot to move the ratchet from 'safety' to 'fire." Like a madman he wrenched himself loose from us, sprang through the door, and darted upstairs. "I'll show you some combustion!" he shouted back fiercely. Kennedy was after him like a flash. "The will!" he cried.
