The machine can be set to deliver a certain number of coins, after which the counting wheel stops automatically.
The toothed wheel being set in motion, the edge of a card or of a funnel-shaped piece of common notepaper is held against the teeth, when a note will be heard arising from the rapidly succeeding displacements of the air in its vicinity.
If, for the single toothed wheel, be substituted a set of four with a common axis, in which the teeth are in the ratios 4: 5: 6: 8, and if the card be rapidly passed along their edges, we shall hear distinctly produced the fundamental chord C, E, G, C 1 and shall thus satisfy ourselves that the intervals C, E; C, G and C, C 1 are, 2 and 2 respectively.
For this purpose the axis is furnished at its upper part with a screw working into a toothed wheel, and driving it round, during each revolution of the plate, through a space equal to the interval between two teeth.
On the completion of each revolution of this toothed wheel (which, if the number of its teeth be 100, will comprise loo revolutions of the movable plate), a projecting pin fixed to it catches a tooth of another toothed wheel and turns it round, and with it a corresponding index which thus records the number of turns of the first toothed wheel.
§ 68 c), consists of a wheel carrying several soft-iron armatures fixed at equal distances Rayleigh's round its circumference.
If the wheel has very little work to do it may not be necessary to apply driving power, and uniform rotation may be maintained by the electro-magnet.
In an experiment described by Rayleigh such a wheel provided with four armatures was used to determine the exact frequency of a driving fork known to have a frequency near 32.
Thus the wheel made about 8 revolutions per second.
If the fork makes exactly 32 vibrations and the wheel 8 revolutions in one pendulum beat, then the positions will be fixed, and every two seconds, the time of a complete pendulum vibration, he will see the two positions looked at flash out in succession at an interval of a second.
But if the fork has, say, rather greater frequency, the hole in the wheel comes round at the end of the two seconds before the bead has quite come into position, and the two flashes appear gradually to move back in the opposite way to the pendulum.
Then the wheel makes 8 N + 1 revolutions in N clock beats, and the fork makes 32 N + 4 vibrations in the same time.
When a cart wheel is ungreased it produces a very high note, probably due to torsional vibrations of the axle.

Money, "the great wheel of circulation," is altogether different from the goods which are circulated by means of it; it is a costly instrument by means of which all that each individual receives is distributed to him; and the expenditure required, first to provide it, and afterwards to maintain it, is a deduction from the net revenue of the society.
Now familiarly known as "wheel 'animalcules," from the wheel-like motion produced by the rings of cilia which generally occur in the head region, the so-called rotatory organs, they were first discovered by A.
This appearance puzzled the older observers, who were led thereby to give the name" wheel-bearers "to the group, until the true character of ciliary motion was recognized; for a wheel cannot be i i organic continuity with the support on which it rotates..
During this time the illusion of a wheel or wheels produced by the ciliary action of the disk had puzzled all observers.

The Pelton water wheel (fig.
The wheel carries a series of cups placed at equal distances around the circumference.
The theoretical efficiency of the wheel would then be Ioo %.
- Pelton Wheel.
On entering, the water flows at first in a radial direction, and then gradually, as it passes through the wheel, it receives a downward component which becomes more and more important.
Another turbine of the mixed flow type is the " Victor," which consists of three parts - the outer guide case, and, inside this, the register gate, and the wheel.
The gate regulates the speed of the wheel by varying the quantity of water; when fully open it merely forms a continuation of the guide passages, and thus offers no obstruction to the flow of the water, but by giving it a movement through a part of a revolution the passages are partly blocked and the flow of the water is checked.
The water passes from the penstock through the guide blades of the upper wheel, and in doing so acts in an upward direction on a cover of the upper wheel, which thus becomes, as it were, a balance-piston.
The wheel is 12 ft.

The former, the old city, lying close to the harbour front, has streets as narrow as is consistent with wheel traffic. Obispo (Pi y Margall in the new republican nomenclature), O'Reilly and San Rafael are the finest retail business streets, and the Prado and the Cerro the handsomest residential streets in the city proper.
They weave and dye several kinds of cloth, tan and dress leather and manufacture oil and soap. Without the assistance of the wheel the women produce a variety of pottery utensils, often of very graceful design, and decorated with patterns in red and black.
If now a wheel W is forced up against q with a pressure equal to the weight of the moving part of the instrument, the whole weight of the moving part would rest upon W in unstable equilibrium; or if a pressure R, less than W, is employed, we have the end friction on the lower bearing removed to an extent = R sin 4),4), and the friction on the bearings of the upper pivot removed to the extent of F cos 4), - where 4 is the latitude of the place.
The wheel W is therefore mounted on a guided rod, which is forced upwards by suitable levers and weights, and this relief of pressure is precisely proportional to the pressure on the respective bearings.

Rotation about a Fixed Axis: Lever, Wheel and Axle.The fixed axis of a turning body is a line fixed relatively to the body and relatively to the fixed space in which the body turns.
In the wheel and axle, motion is received and transmitted by two cylindrical surfaces of different radii described about their common fixed axis of turning, their velocity-ratio being that of their radii.
When the point of contact of two wheels lies between theim centres, they are said to be in outside gearing; when beyond theii centres, ip inside gearing, because the rolling surface of the larger wheel must in this case be turned inward or towards its centre.
A rack, to work with a circular wheel, must be straight.
To work with a wheel of any other figure, its section must be a rolling curve, subject to the condition that the perpendicular distance from the pole or centre of the wheel to a straight line parallel to the direction of the motion of the rack shall be constant.
Let r1 be the radiusvector of a point of contact on the wheel, Xi the ordinate from the straight line before mentioned to the corresponding point of contact on the rack.
98, in which case it is a disk wheel.
One of those consists in forming the rim of each wheel into a series of alternate ridges and grooves parallel to the plane of rotation; it is applicable to cylindrical and bevel wheels, but not to skew-bevel wheels.
Sliding Contact (direct): Teeth of Wheels, their Number anc PitchThe ordinary method of connecting a pair of wheels, or wheel and a rack, and the only method which ensures the exaci maintenance of a given numerical velocity ratio, is by means of i series of alternate ridges and hollows parallel or nearly parallel t(the successive lines of contact of the ideal smooth wheels whon velocity ratio would be the same with that of the toothed wheels The ridges are called teeth; the hollows, spaces.
The pitch-surface of a wheel lies intermediate between the points of the teeth and the bottoms of the hollows between them.
Separate teeth, fixed into mortises in the rim of the wheel, are called cogs.
The radius of the pitch-circle of a wheel is called the geometrical radius; a circle touching the ends of the teeth is called the addendum circle, and its radius the real radius; the difference between these radii, being the projection of the teeth beyond the pitch-surface, is called the addendum.
In order that a pair of wheels, or a wheel and a rack, may work correctly together, it is in all cases essential that the pitch should be the same in each.
Let t, T be a pair of teeth in the smaller and larger wheel respectively, which at a particular instant work together.
It is required to find, first, how many pairs of teeth must pass the line of contact of the pitch-surfaces before I and T work together again (let this number be called a); and, secondly, with how many different teeth of the larger wheel the tooth t will work at different times (let this number be called b); thirdly, with how many different teeth of the smaller wheel the tooth T will work at different times (let this be called c)
It is considered desirable by millwrights, with a view to thi preservation of the uniformity of shape of the teeth of a pair 01 wheels, that each given tooth in one wheel should work with a~ many different teeth in the other wheel as possible.
Sliding Contact: Forms of the Teeth of Spur-wheels am Racks.A line of connection of two pieces in sliding contact is line perpendicular to their surfaces at a point where they touch Bearing this in mind, the principle of the comparative motion of pair of teeth belonging to a pair of spur-wheels, or to a spur-whee and a rack, is found by applying the principles stated generally ii 36 and 37 to the case of parallel axes for a pair of spur-wheels, am to the case of an axis perpendicular to the direction of shifting for wheel and a rack.
Let the wheel I be the driver, and the wheel 2 th follower.
The relative velocity pet-pendicular to P~Pi of the teeth at their point of contactthat is, their velocity of sliding on each otheris found by supposing one of the wheels, such as I, to be fixed; the line of centres CXCi to rotate backwards round C~ with the angular velocity aj, and the wheel 2 to rotate round C2 as before, with the angular velocity az relatively to the line of centres CiC2, so as to, have the same motion as if its pitch-circle rolled,on the pitch-circle of the first wheel.
~s Now, suppose a tracing point T Pa to be fixed to the cord, so as to be carried along the path of con- Dz a tact P11P2, that point will trace on a plane rotating along with the wheel I part of the involute of the base-circle DfD1, and on a plane rotating along with the wheel 2
Consequently, one of the forms suitable for the teeth of wheels is the involute of a circle; and the obliquity of the action of such teeth is the angle whose cosine is the ratio of the radius of their base-circle to that of the pitch-circle of the wheel.
103) be rolled on the inside of the pitch-circle BB of a wheel, it appears, from 30, that the instantaneous axis of the rolling curve at any instant will T a be at the point I, where it ~ E
traced by a tracing-point T, fixed to the rolling curve upon the plane of the wheel, will be avery- T
For a smaller pitch-circle the flanks would be convex and in- curved or under-cut, which would be inconvenient; therefore the C smallest wheel of a set should FIG.
In fig~ I04 let BB be part of the pitch-circle of a wheel with epicycloidal teeth; dC the line of centres; I the pitch-point; EIE.
For the proportions approved of by Willis, sin 0 = 3/4 nearly; r = (the pitch) nearly; c=1/2p nearly; and, if N be the number of teeth in the wheel, r/R =6/N nearly; therefore, approximately, p C=~.
Trundles and Pin-Wheels.If a wheel or trundle have cylindrical pins or staves for teeth, the faces of the teeth of a wheel suitable for driving it are described by first tracing external epicycloids, by rolling the pitch-circle of the pin-wheel or trundle on the pitch-circle of the driving-wheel, with the centre of a stave for a tracing-point, and then drawing curves parallel to, and within the epicycloids, at a distance from them equal to the radius of a stave.
The clearance allowed between the points of teeth and the bottoms of the spaces between the teeth of the other wheel is about one-tenth of the pitch.
A wheel thus formed resembles in shape a series of equal and similar toothed disks placed side by s de, with the teeth of each a little behind those of the preceding isk.
Teeth of Skew-Bevel Wheels.The crests of the teeth of a skew-bevel wheel are parallel to the generating straight line of the hyperboloidal pitch-surface; and the transverse sections of the teeth at a given pitch-circle are similar to those of the teeth of a bevelwheel whose pitch surface is a cone touching the hyperboloidal surface at the given circle.
When one is of considerably greater diameter than the other, the larger is commonly called in practice a wheel, the name screw being applied to the smaller only; but they are nevertheless both screws in fact.
To make the teeth of a pair of endless screws fit correctly and work smoothly, a hardened steel screw is made of the figure of the smaller screw, with its thread or threads notched so as to form a cutting tool; the larger screw, or wheel, is cast approximately of the required figure; the larger screw and the steel screw are fitted up in their proper relative position, and made to rotate in contact with each other by turning the steel screw, which cuts the threads of the larger screw to their true figure.
Let the axis Ai carry a wheel of N1 teeth, driving a wheel of ni teeth on the axis Ai, which carries also a wheel of N2 teeth, driving a wheel of 113 teeth on the axis A3, and so on; the numbers of teeth in drivers being denoted by Ns, and in followers by ns, and the axes to which the wheels are fixed being denoted by numbers.
