He rolled the ratchet of his static gun and Asher was hurled to the floor by the heavy shock.
Asher increased the pressure of his ratchet trigger.
Asher's finger pulled the ratchet trigger full force, and like dew before a strong shaft of sunlight, the gruesome Things were knocked away.
The ratchet arm moves up and down in a spiral groove, the groove being in a shield attached by screws to the cylinder; on the ratchet-band there is a pall and two springs, one under the other.
On the return of the piston, the pall drops into the ratchet and then the piston is turned.
The drill-bar is rotated by means of a ratchet operated by a spiral groove in the shield of the machine.
The rotatingratchet is in the band of the cylinder and has a spline in it, and a pall on its outside.
The motion of the piston raises the lever up, pressing the end containing the pall against the ratchet which turns the nut on the feed-screw, thus moving the machine forward.
The piston having a spiral groove is turned by this ratchet as it moves down.
On the end of this feed-nut is a ratchet gear covered by a ratchet-band with an arm upon it, all moving with the piston.
D represents a concealed ratchet in which the cam ring governs the ratchet, and, being in line with the bit, makes it more convenient in handling than when it is at right angles.
E is the ratchet box, and this shows the gear teeth cut on the extra heavy spindle, and encased, so that the user's hands are protected from the teeth.
The ratchet mechanism is interchangeable, and may be taken apart by removing one screw.
The ratchet parts are entirely enclosed, thus keeping out moisture and dirt, retaining lubrication and protecting the users' hands.
The open ratchet (F) shows the gear pinned to the spindle and exposed.
The pawls offer no resistance to the ratchet teeth, which push them up into the semicircular recesses in the chain-ring.
It is a ratchet specially suited for this kind of work.
When the rider ceases to pedal, the chain-ring becomes stationary, but the ratchet continues to revolve.
A ratchet prevents the arbor from being turned backwards by the spring.
The ring on which the three pawls and springs are carried is screwed on the end of the hub; the chain-wheel is combined with an inner ratchet wheel and is mounted by two rows of ball bearings on the pawl ring.
There are three principal types of free-wheel clutches--roller, ratchet and friction cone.
When the sun-wheel D is released, the planet carrier C drives the annular wheel A by the ratchet free-wheel clutch; the part thus revolves as a solid piece, and gives the normal or low speed.
A sectional view of a ball-bearing ratchet free-wheel, with outer cover removed, is shown in fig.
The teeth of the ratch and ratchet have so gentle an inclination on one side of each, that although the ratch applies force to the ratchet in the upward direction, they slide freely over in their return.
Let us further conceive that all of these ratchet wheels are provided with a notch or a hole or a projection, alike in all respects at all stations save in the position which this notch or hole or projection occupies on the wheel.
The ratchet wheel is stepped around automatically by each impulse of current from an ordinary pole changer such as is employed in ringing biased bells.
The ratchet wheels, therefore, are all stepped in unison.
There is thus one of these driving magnets at each station, each bridged across the line so that when a single impulse of current is sent out from the central office all of the ratchet wheels will be moved one step.
The ratchet 3 in this case is not a complete wheel but rather a segment thereof, and it is provided with a series of notches of different depths.
Another impulse will move all of the ratchet wheels another step, and so on throughout any desired number of impulses.
The brake rod reaches from the upper end of the lever elbow to the foot ratchet at the front end of the wagon box.
Two sizes of braces are needed, a small brace for small pod bits and twist drills, and a largeratchet brace with a 6-inch crank radius for turning larger bits.
They went out on the other platform and kicked the ratchet out and let the wheel spin.
There was a clock under a glass cover on the chimney-piece whose works you could see through, with a fascinating ratchet movement of perfect grace and punctuality.
Nor is she, in the sense in which her statement has been accepted, for she comes downstairs within seven by the clock with the dutiful ratchet movement.
There is, however, an important difference in the magazine, which has no spiral spring, but is furnished instead with an ingenious system of ratchet bars.
The act of closing the spring cover again brings the two ratchet bars into play.
The magazine is loaded through an aperture in the butt plate, the opening of the spring cover of which causes the tworatchet bars to be depressed, so that the magazine can be filled by passing the cartridges along a smooth middle bar.
This rack is cut into ratchet teeth as at w, in which enters the catch o, as impelled by a proper spring acting on it, (but not seen in the figure.
This operation might be performed by a handle put on the axis of the Machine, accompanied by a ratchet on the wheel, just like the similar parts of a jack for roasting.
The Barrel on which the cords are wound possesses a metal cap in front, and a ratchet or toothed wheel at the back end; between this cap and ratchet is a metal drum or tube adapted to the width of the Frame.
Fitted to the fly-frame is a ratchet with two clicks and springs, these being used to prevent the train being stopped too suddenly, and the damage likely to arise therefrom.
This is acted upon by a click, which, falling into the ratchet teeth, prevents the recoil of the mainspring, so that the spring has no means of uncoiling itself, except by the moving of the train of wheels.
The shaft B, to which is attached a driving pulley, C, and a ratchet wheel, D, is fitted in holes drilled through the diameter of the body.
Adjusting the diaphragm contact on the ratchet wheel will change the tone of the horn.
A spring catch kept the ratchet wheel in place at the end of each forward rotation of the wheel by the pawl.
In 1780, one was erected at Birmingham, where theratchet work was found to be subject to such objections, that one of the persons about the works substituted for it the simple crank, which has since been invariably used.
On the inward stroke the ratchet is held fast by the pawls, and the piston and bit are forced to rotate through a small part of a revolution.
On the outward stroke, j, with its ratchet k, is free to turn under a couple of pawls and springs, and consequently the piston delivers its blow without rotation.
The brakesman is supplied with a convenient seat and footboard, and on the floor-level of the latter there is a pawl and ratchetattached to the vertical rod, which permits the brakes to be applied to the extent required.
The brakesman has merely to put it on, the pawl and ratchet keep it on, and the bow springs take it off when no longer required.
