Each separate strand passes through the eye of a faller, which, should the fibre break, falls down and instantly stops the machine, thus effectually calling attention to the fact that a thread has failed.
Numerous attempts have been made to simplify the silk-throwing by combining two or more operations on one machine, but not as yet with much success.
Thence the silk is taken to a washing machine, and the loosened gum thoroughly washed away.
When the waste contains any large percentage of worm or chrysalis, it is taken to a " cocoon beater," a machine which has a large revolving disk on which the silk is put, and while revolving slowly is beaten by a leather whip or flail, which loosens the silk and knocks out the wormy matter.
When the teeth are full the machine is stopped, and the silk stripped off the drum, then presenting a sheet-like appearance technically known as a " lap."
The silk drawn by the rows of teeth on the drum through the porcupine rollers (or porcupine sheets in some cases) covers the whole of the drum, hooked at certain intervals round the teeth; and when a sufficient weight is on the machine, it is stopped, and an attendant cuts, with a knife, the silk along the back of each row of teeth, thus leaving a fringe of silk hooked on the pins or teeth.
This fringe of silk is placed by the attendant between two hinged boards, and whilst held firmly in these boards (called book-boards) is pulled off the machine, and is called a " strip "; the part which has been hooked round the teeth is called the " face," and the other portion the " tail."
In each machine the object is the same.
This fibre again yields combings which will also be combed, and so on for five or six times until the combings are too short, and are taken from the machine and known as noils.
The flat frame is the most gentle in its usage of the silk, but is most costly in labour; whilst the circular frame, being more severe in its action, is not suitable for the thoroughly degummed silks, but on the other hand is best for silks containing much wormy matter, because the silk hanging down into the combing teeth is thoroughly cleansed of such foreign matter, which is deposited under the machine.
A faller or gill drawing machine consists of a long feeding sheet which conveys silk to a pair of rollers (back rollers).
This lap is sometimes re-spread to make it more even, and at other times taken to a drawing machine which delivers in a sliver form.
Eight or more slivers are put behind the first drawing head, conveyed through the fallers and made into one sliver in front of the machine.
From the last head of drawing the sliver is taken to a machine known as a gill rover.
This is a drawing machine fitted with fallers through which the sliver is drawn, but the end from the front roller is wound on to a bobbin.
The machine is fitted with 20 to 40 of these bobbins placed side by side, and its product is known as " slubbing roving," it being now a soft, thick thread of silk, measuring usually either 840 or 1260 yds.
Hitherto all the drawing has been by rollers and fallers, but in the next machine the drawing is done by rollers only.
Two or three slubbing rovings are put up behind the machine opposite each spindle; each end is guided separately into back rollers and thence between smaller rollers, known as carrier rollers, to the front rollers.
The fibre and nibs have to be cleaned off by means of a gassing machine so constructed that the end of silk (silk yarn) is frictioned to throw off the nibs, and at the same time is run very rapidly through a gas flame a sufficient number of times to burn off the hairy and fibrous matter without injuring the main thread.

But the fibre produced by these rapid and economical means was very inferior in quality to the product of Maori handiwork, mainly because weak and undeveloped strands are, by machine preparation, unavoidably intermixed with the perfect fibres, which alone the Maoris select, and so the uniform quality and strength of the material are destroyed.
The New Zealand government in 1893 offered a premium of £1750 for a machine which would treat the fibre satisfactorily, and a further £250 for a process of treating the tow; and with a view to creating further interest in the matter a member of a commission of inquiry visited England during 1897.

Such arc the phenomena of the action of a machine, arranged in the order of can sation.
But in studying or treating of, the theory of machines, the order of simplicity is the best; and in this order the first branch of the subject is the modification of motion and force by the train of mechanism; the next is the effect or purpose of the machine; and the last, or most complex, is the action of the prime mover.
When the pressure and temperature of the air can be maintained constant, this machine fulfils equation (2), like the hydraulic press.
Motions ClassedIn problems of mechanism, each solid piece of the machine is supposed to be so stiff and strong as not to undergo any sensible change of figure or dimensions by the forces applied to ita supposition which is realized in practice if the machine is skilfully designed.
They there fore study that the numbers of teeth in each pair of wheels whici work together shall either be prime to each other, or shall hav their greatest common divisor as small as is consistent with velocity ratio suited for the purposes of the machine.
One train of mechanism may diverge into two or moreas when a single shaft, driven by a prime mover, carries several pulleys, each of which drives a different machine.
Laws of Motion.-The action of a machine in transmitting force and motion simultaneously, or performing work, is governed, in common with the phenomena of moving bodies in general, by two laws of motion.
Thus, the weight of each separate piece in a machine is treated as acting wholly at its centre of gravity, and each pressure applied to it as acting at a point called the centre of pressure of the surface to which the pressure is really applied.
Work is distinguished into useful work and prejudicial or lost work, according as it is performed in producing the useful effect of the machine, or in overcoming prejudicial resistance.
Principle of the Equality of Energy and Work.FroIn the first law of motion it follows that in a machine whose pieces move with uniform velocities the efforts and resistances must balance each other.
This principle, applied to a machine whose parts move with uniform velocities, is equivalent to saying that in any given interval of time the energy exerted is equal to the work performed.
It is shown that a machine may at any instant be represented by a frame of links the stresses in which are identical with the pressures at the joints of the mechanism.
The more nearly the efficiency of a machine approaches to unity the better is the machine.
Power and Effect.The power of a machine is the energy exerted, and the effect the useful work performed, in some interval of time of definite length, such as a second, an hour, or a day.
Modulus of a Machine.In the investigation of the properties of a machine, the useful resistances to be overcome and the useful work to be performed are usually given.
The result of this investigation, expressed in the form of an equation between this energy and the useful work, is called by Moseley the modulus of the machine.
In oruer to diminish that pressure to the smallest possible amount, the effort, and the resultant of the useful resistance, and the weight of the piece (called above the given force) ought to be opposed to each other as directly as is practicable consistently with the purposes of the machine.
Of this kind is the weight of any piece in the mechanism whose centre of gravity alternately rises and falls; for during the rise of the centre of gravity that weight acts as a resistance, and energy is employed in lifting it to an amount expressed by the product of the weight into the vertical height of its rise; and during the fall of the centre of gravity the weight acts as an effort, and exerts in assisting to perform the work of the machine an amount of energy exactly equal to that which had previously been employed in lifting it.
Hence, unless there be some reason to the contrary, each piece of a machine should be balanced on its axis of rotation; otherwise the centrifugal force will cause strains, vibration and increased friction, and a tendency of the shafts to jump out of their bearings.
It is essential to the steady motion of every rapidly rotating piece in a machine that its axis of rotation should not merely traverse its centre of gravity, but should be a permanent axis; for otherwise the centrifugal couples will increass friction, produce oscillation of the shaft and tend to make it leave its bearings.
When a weight is reciprocated, the equal and opposite force required for its acceleration at any instant appears as an unbalanced force on the frame of the machine to which the weight belongs.
General Principles.In order that the velocity of every piece of a machine may be uniform, it is necessary that the forces acting on each piece should be always exactly balanced.
Also, in order that the forces acting on each piece of a machine may be always exactly balanced, it is necessary that thevelocityof that piece should be uniform.
When a machine is being started from a state of rest, and brought by degrees up to its proper speed, the effort must be in excess; when it is being retarded for the purpose of stopping it, the resistance must be in excess.
When a machine undergoes alternate acceleration and retardation, so that at certain instants of time, occurring at the end of intervals called periods or cycles, it returns to its original speed, then in each of those periods or cycles the alternate excesses of energy and of work neutralize each other; and at the end of each cycle the principle of the equality of energy and work stated in 87, with all, its consequences, is verified exactly as in the case of machines of uniform speed.
In any given interval during the working of a machine, the energy exerted added to the energy restored is equal to the energy stored added to the work performed.
Flywheels.A flywheel is a rotating piece in a machine, generally shaped like a wheel (that is to say, consisting of a rim with spokes), and suited to store and restore energy by the periodical variations in its angular velocity.
Let e denote the quantity by which the energy exerted in each cycle of the working of the machine alternately exceeds and falls short of the work performed, and which has consequently to be alternately stored by acceleration and restored by retardation of the flywheel.
Brakes.A brake is an apparatus for stopping and diminishing the velocity of a machine by friction, such as the friction-strap already referred to in 103.
To find the distance s through which a brake, exerting the friction F, must rub in order to stop a machine having the total actual energy E at the moment when the brake begins to act, reduce, by the principles of 96, the various efforts and other resistances of the machine which act at the same time with the friction of the brake to the rubbing surface of the brake, and let R be their resultantpositive if resistance, negative if effort preponderates.

In 1873 at Vienna the fact was discovered that a dynamo machine of the Gramme type could also act as an electric motor and jwas set in rotation when a current was passed into it from another similar machine.
On the smooth surface the seed is sown broadcast by hand or machine, at the rate of 3 bushels per acre, and covered in the same manner as clover seeds.
The breaking is done by passing the stalks between grooved or fluted rollers of different pitches; these rollers, of which there may be from 5 to 7 pairs, are sometimes arranged to work alternately forwards and backwards in order to thoroughly break the woody material or " boon " of the straw, while the broken " shoves " are beaten out by suspending the fibre in a machine fitted with a series of revolving blades, which, striking violently against the flax, shake out the bruised and broken woody cores.
In England the broad distinction between " presses " and " machines " is generally considered to rest in the fact that the former are worked by hand, and the latter by steam, gas or electricity; and the men who work by these two methods are called respectively " pressmen " and " machine minders " or " machine managers."
It was left to Friedrich Ktinig (1774-1833), a German, to produce the first really practical printing machine.
Two other classes of presses of somewhat different design were largely in operation in the middle of the r9th century - the " double platen," which still printed only one side at each impression from each end, and the " perfecting machine," which was made with two large cylinders and printed from two typeformes placed on separate beds.
Although the latter machine turned out sheets printed on both sides before it delivered them (hence its name), the second impression was still a distinct operation.
A machine of this kind, if it printed a sheet of double demy, which measures 35 X 221 in., was about 13 ft.
There were two type beds and two inking tables, which travelled backwards and forwards, and one platen only, situated in the middle of the machine, which in turn gave the needful impression as the type-formes passed underneath.
The sheets were laid or fed to certain marks between the frisket and tympan, and when these were closed together the carriage was propelled under the platen and the impression was given to that portion of the machine, while at the other end another sheet was being fed in ready to receive its impression in due course.
The perfecting machine has had a great vogue, and has been much improved from time to time, especially in America, though the two-revolution machine in recent years superseded it, whether temporarily or not being still uncertain.
In this class of machine various improvements were made from time to time by different manufacturers, each profiting by the experiences of the others, and two kinds of such revolving presses may now be given as examples.
After many experiments Augustus Applegath (1789-1871) in 1848 constructed for The Times (London), a machine which was an eight-feeder, built entirely on the cylindrical principle, the cylinders placed not in a horizontal but in a vertical position.
This was accomplished by the construction of cast-iron beds, one for each separate page (not column, as in Applegath's machine).
Hoe's first presses were four-feeders, but as many as ten feeds were supplied, as in the case of the two presses built to replace the Applegath machine for The Times, each of which produced about 2000 impressions from each feed, making a total of 20,000 per hour, printed on one side, or from two machines 20,000 sheets printed on both sides.
Bullock (1813-1867) of Philadelphia who in 1865 invented the first machine to print from a continuous web of paper.
Perfecting machines, usually with two cylinders, and printing or " perfecting " both sides of a sheet before it leaves the machine, but with two distinct operations.
Two-colour machines, usually made with one feed, that is, with only one cylinder, but with two printing surfaces, and two sets of inking apparatus one at each end of the machine.
The modern single or " stop " cylinder, quite different in construc- Wharfe= tion from the old single cylinder machines, largely suc dale" ceeded the double platen machine.
All the accessories for inking are placed at the end of the machine, the ink itself being supplied from a ductor, which can be so regulated by the keys attached to it as to let out the precise amount of pigment required.
This revolves with the run of the machine and at the same time has a slight reciprocating action which helps the distribution.
The perfecting machine is so named because it produces sheets printed on both sides or, in technical language, " perfected."
This perfecting class of machine has been in use a great many years, Machines.
The frame of the machine, owing to the fact that it contains two carriages and a double inking apparatus, is long, the exact size depending on the size of the sheet to be printed.
The AngloFrench perfecting machine is one of that class.
The two-revolution machine is another one-cylinder machine built on the reciprocating principle.
In the first case a bar descends upon the paper after it is laid to point marks, and this bar, having a rotary motion, runs the sheet between a roller and a small drum into the machine.
The web arrangement consists of a series the high over-feedboard, and the taking-off apparatus is automatic but on a different plan from that of the ordinary Wharfedale, the sheets being carried over tapes with the freshly-printed side uppermost, thus preventing smearing; they are then carried on to the heap or pile by the frame or long arms placed at the end of the machine.
A recent feature of this machine is the tandem equipment, whereby two, three or even four machines may be coupled together for colour work.
These plates were then fixed on the beds of the Hoe type revolving machine, which were adapted to receive them instead of the movable typeformes previously used.
The two-colour machine is generally a single cylinder (fig..8) with one feed only, and the bed motion reciprocating.
A double inking apparatus is of course necessary, and the inking arrangements are placed at the two extreme ends of the machine.
In comparison with the ordinary single cylinder the two-colour machine is built with a longer frame, as is necessary to allow the two type-formes to pass under the cylinder, both in its travel forward and on its return.
This cylinder on its return is stationary, in fact it might be called a double or rather an alternative stop-cylinder machine, with the inking facilities arranged somewhat on the same plan as on either a two-feeder or a perfecting machine.
These two-colour presses are intended only for long runs, short runs may be worked to advantage separately on the ordinary single-colour machine.
Generally, with the exception just mentioned, the machine is much the same as the ordinary stop or Wharfedale.
