The limit to which it may be practicable to multiply ratchets or toothed bands will, of course, depend upon the thickness of the spur-wheel, and when this latter has been greatly enlarged, with the object of providing for this feature, it becomes virtually a steel drum having bevelled steps accurately cut longitudinally upon its periphery.
Then the local smith came to the aid of the "domestic" or serf, and hammered into shape what were termed andirons, their use making it easier to light the logs, giving a current of air under them, causing them to burn brighter. The andirons were afterwards called fire-dogs, and in course of time bars rested on hooks or ratchets, or were laid across the dogs.
The piston rods are formed with conical ends for fitting into the piston, but are coned the reverse way as in locomotives, and are secured in the piston by nuts on the ends of the rods, these nuts being provided with ratchets to prevent them from unscrewing accidentally. Q. What species of slide valve is employed? A. The ordinary three ported valve, and it is set on the top of the cylinder.
This was a box like the bed of a wagon, with a windlass at each end, with levers, and ratchets to prevent slipping; over each windlass went chains; some were fastened to the ankles of the sufferer; others to his wrists.
"What we most need, to secure honest elections," says a well-meaning reformer, "is the Clifford or the Myers voting machine." Why, truly, here is a hopeful spirit a rare and radiant intelligence suffused with the conviction that men can be made honest by machinery that human character is a matter of gearing, ratchets and dials! One would give something to know how it feels to be like that.
The shock occasioned by the blow of the ratchet on the spur-wheel, or of one tooth upon another, may be reduced almost to vanishing point by multiplying the number of ratchets or toothed bands, and placing the effective ends, which engage in the teeth of the wheel successively, one very slightly in advance of the other.
In the gas-operated arms, a small hole is drilled in the under side of the barrel, six to eight inches from the muzzle, so that, when the bullet has passed this point, and during the time it takes it to traverse the remaining few inches to the muzzle, a certain portion of the enclosed gas is forced through this hole, where it is "trapped," in a small "gas-chamber" and its force directed against a piston or lever which, being connected with the necessary working parts of the gun by cams, links or ratchets, performs the functions of removing and ejecting the empty cartridge case, withdrawing a new cartridge from the belt, clip or magazine, and "cocking" the gun: that is, forcing the "hammer" or striker back and compressing its spring.
Roby, a spectre huntsman known by the name Gabriel Ratchets, accompanied by a pack of phantom hounds, is said to hunt a milk-white doe round the Eagle's Crag in the Vale of Todmorden every All Hallows Eve. These hounds were also seen in Norfolk. A famous ecclesiast, when on his way to the coast, was forced to spend the night in the King's Lynn Inn, owing to a violent snowstorm.
In this way the machine is so arranged that, no matter at what point the stroke imparted by the movement of the buoy may be arrested, there is always one or other of the ratchets or of the teeth which will fall into engagement with the tooth of the spur-wheel, very close to its effective face, and thus the momentum acquired by the one part before it impinges upon the other becomes comparatively small.
Doesn't it make you feel rather small and otherwise unworthy when you see the kind of street these fellow-beings of yours live in, and then think how particular you are about locality and the number of bellpulls? I don't see even ratchets and speaking-tubes at these doors."
