Lenin’s and Stalin’s form of communism is gone, yet its trappings have been expropriated by mega-corporations. We have companies featuring central planning by troikas, mission statements crafted by apparatchiks, five-year plans, no right to choose leaders in companies, no democracy in the workplace, a clear distinction between intelligentsia and peasants (top CEOs make 152 times the median salary and enjoy company dachas, jets, and limos), and state monitoring (time<b> clocks, dress codes, drug screening, “employee assistance” plans, e-mail monitoring, no smoking, and other personal conduct rules, as well as family-life audits).
Some folk's tongues are like the clocks as run on strikin', not to tell you the time o' the day, but because there's summat wrong i' their inside.
Unless hours were cups of sack, and minutes capons, and clocks the tongues of bawds, and dials the signs of leaping houses, and the blessed sun himself a fair, hot wench in flame-colored taffeta, I see no reason why thou shouldst be so superfluous to demand the time of the day. I wasted time and now doth
-- William Shakespeare
I lighted my fire, which burnt with a raw pale flare at that time of the morning, and fell into a doze before it. I seemed to have been dozing a whole night when the clocks struck six. As there was full an hour and a half between me and daylight, I dozed again; now, waking up uneasily, with prolix conversations about nothing, in my ears; now, making thunder of the wind in the chimney; at length, falling off into a profound sleep from which the daylight woke me with a start.
She answered in a low whisper and with caution: "I had been shut up in these rooms a long time (I don't know how long; you know what time the clocks keep here), when I told him that I wanted a little girl to rear and love, and save from my fate. I had first seen him when I sent for him to lay this place waste for me; having read of him in the newspapers, before I and the world parted. He told me that he would look about him for such an orphan child. One night he brought her here asleep, and I called her Estella."
When the afternoon arrived and he felt that the hour was drawing near, he wished for solitude, his agitation was extreme; a simple question from a friend would have irritated him. He shut himself in his room, and tried to read, but his eye glanced over the page without understanding a word, and he threw away the book, and for the second time sat down to sketch his plan, the ladders and the fence. At length the hour drew near. Never did a man deeply in love allow the clocks to go on peacefully. Morrel tormented his so effectually that they struck eight at half-past six. He then said, "It is time to start; the signature was indeed fixed to take place at nine o'clock, but perhaps Valentine will not wait for that." Consequently, Morrel, having left the Rue Meslay at half-past eight by his timepiece, entered the clover-field while the clock of Saint-Phillippe du Roule was striking eight. The horse and cabriolet were concealed behind a small ruin, where Morrel had often waited.
Valentine was alone; two other clocks, slower than that of Saint-Philippe du Roule, struck the hour of midnight from different directions, and excepting the rumbling of a few carriages all was silent. Then Valentine's attention was engrossed by the clock in her room, which marked the seconds. She began counting them, remarking that they were much slower than the beatings of her heart; and still she doubted,--the inoffensive Valentine could not imagine that any one should desire her death. Why should they? To what end? What had she done to excite the malice of an enemy? There was no fear of her falling asleep. One terrible idea pressed upon her mind,--that some one existed in the world who had attempted to assassinate her, and who was about to endeavor to do so again. Supposing this person, wearied at the inefficacy of the poison, should, as Monte Cristo intimated, have recourse to steel!--What if the count should have no time to run to her rescue!--What if her last moments were approaching, and she should never again see Morrel! When this terrible chain of ideas presented itself, Valentine was nearly persuaded to ring the bell, and call for help. But through the door she fancied she saw the luminous eye of the count--that eye which lived in her memory, and the recollection overwhelmed her with so much shame that she asked herself whether any amount of gratitude could ever repay his adventurous and devoted friendship.
So unchanging was the dull old house, the yellow light in the darkened room, the faded spectre in the chair by the dressing-table glass, that I felt as if the stopping of the clocks had stopped Time in that mysterious place, and, while I and everything else outside it grew older, it stood still. Daylight never entered the house as to my thoughts and remembrances of it, any more than as to the actual fact. It bewildered me, and under its influence I continued at heart to hate my trade and to be ashamed of home.
The length of pendulum rods is also affected by temperature and also, if they are made of wood, by damp. Hence, to ensure good time-keeping qualities in a clock, it is necessary (1) to make the rods of materials that are as little affected by such influences as possible, and (2) to provide means of compensation by which the effective length of the rod is kept constant in spite of expansion or contraction in the material of which it is composed. Fairly good pendulums for ordinary use may be made out of very well dried wood, soaked in a thin solution of shellac in spirits of wine, or in melted paraffin wax; but wood shrinks in so uncertain a manner that such pendulums are not admissible for clocks of high exactitude. Steel is an excellent material for pendulum rods, for the metal is strong, is not stretched by the weight of the bob, and does not suffer great changes in molecular structure in the course of time. But a steel rod expands on the average lineally by .0000064 of its length for each degree F. by which its temperature rises; hence an expansion of .00009 in. on a pendulum rod of 39.14 in., that is .000023 of its length, will be caused by an increase of temperature of about 4° F., and that is sufficient to make the clock lose a second a day. Since the summer and winter temperatures of a room may differ by as much as 50° F., the going of a clock may thus be affected by an error of 12 seconds a day. With a pendulum rod of brass, which has a coefficient of expansion of .00001, a clock might gain one-third of a minute daily in winter as compared with its rate in summer. The coefficients of linear expansion per degree F. of some other materials used in making pendulums are as follows: white deal, .0000024; flint glass, .0000048; iron, .000007; lead, .000016; zinc, .000016; and mercury, .000033. The solid or cubical expansions of these bodies are three times the above quantities respectively. Entry: 1
If the clock is required to strike quarters, a third "part" or train of wheels is added on the right hand of the going part; and its general construction is the same as the hour-striking part; only there are two more bells, and two hammers so placed that one is raised a little after the other. If there are more quarter-bells than two, the hammers are generally raised by a chime-barrel, which is merely a cylinder set on the arbor of the striking-wheel (in that case generally the third in the train), with short pins stuck into it in the proper places to raise the hammers in the order required for the tune of the chimes. The quarters are usually made to let off the hour, and this connexion may be made in two ways. If the chimes are different in tune for each quarter, and not merely the same tune repeated two, three and four times, the repetition movement must not be used for them, as it would throw the tunes into confusion, but the old locking-plate movement, as in turret clocks; and therefore, if we conceive the hour lifting-piece connected with the quarter locking-plate, as it is with the wheel N, in fig. 26, it is evident that the pin will discharge the hour striking part as the fourth quarter finishes.

The general construction of the going part of all clocks, except large or turret clocks, is substantially the same, and fig. 3 is a section of any ordinary house clock. B is the barrel with the cord coiled round it, generally 16 times for the 8 days; the barrel is fixed to its arbor K, which is prolonged into the winding square coming up to the face or dial of the clock; the dial is here shown as fixed either by small screws x, or by a socket and pin z, to the prolonged pillars p, p, which (4 or 5 in number) connect the plates or frame of the clock together, though the dial is commonly set on to the front plate by another set of pillars of its own. The great wheel G rides on the arbor, and is connected with the barrel by the ratchet R, the action of which is shown more fully in fig. 25. The intermediate wheel r in this drawing is for a purpose which will be described hereafter, and for the present it may be considered as omitted, and the click of the ratchet R as fixed to the great wheel. The great wheel drives the pinion c which is called the centre pinion, on the arbor of the _centre wheel_ C, which goes through to the dial, and carries the long, or minute-hand; this wheel always turns in an hour, and the great wheel generally in 12 hours, by having 12 times as many teeth as the centre pinion. The centre wheel drives the "second wheel" D by its pinion d, and that again drives the scape-wheel E by its pinion e. If the pinions d and e have each 8 teeth or _leaves_ (as the teeth of pinions are usually called), C will have 64 teeth and D 60, in a clock of which the scape-wheel turns in a minute, so that the seconds hand may be set on its arbor prolonged to the dial. A represents the pallets of the escapement, which will be described presently, and their arbor a goes through a large hole in the back plate near F, and its back pivot turns in a cock OFQ screwed on to the back plate. From the pallet arbor at F descends the _crutch_ Ff, ending in the _fork_ f, which embraces the pendulum P, so that as the pendulum vibrates, the crutch and the pallets necessarily vibrate with it. The pendulum is hung by a thin spring S from the cock Q, so that the bending point of the spring may be just opposite the end of the pallet arbor, and the edge of the spring as close to the end of that arbor as possible.

Electricity is applied to clocks in three main ways:--(1) in actuating timepieces which measure their own time and must therefore be provided with pendulums or balance wheels; (2) in reproducing on one or more dials the movements of the hands of a master clock, by the aid of electric impulses sent at regular intervals, say of a minute or a half-minute; and (3) in synchronizing ordinary clocks by occasional impulses sent from some accurate regulator at a distance.

Huygens had before this time fixed his abode in France. In 1665 Colbert made to him on behalf of Louis XIV. an offer too tempting to be refused, and between the following year and 1681 his residence in the philosophic seclusion of the Bibliothèque du Roi was only interrupted by two short visits to his native country. His _magnum opus_ dates from this period. The _Horologium oscillatorium_, published with a dedication to his royal patron in 1673, contained original discoveries sufficient to have furnished materials for half a dozen striking disquisitions. His solution of the celebrated problem of the "centre of oscillation" formed in itself an important event in the history of mechanics. Assuming as an axiom that the centre of gravity of any number of interdependent bodies cannot rise higher than the point from which it fell, he arrived, by anticipating in the particular case the general principle of the conservation of _vis viva_, at correct although not strictly demonstrated conclusions. His treatment of the subject was the first successful attempt to deal with the dynamics of a system. The determination of the true relation between the length of a pendulum and the time of its oscillation; the invention of the theory of evolutes; the discovery, hence ensuing, that the cycloid is its own evolute, and is strictly isochronous; the ingenious although practically inoperative idea of correcting the "circular error" of the pendulum by applying cycloidal cheeks to clocks--were all contained in this remarkable treatise. The theorems on the composition of forces in circular motion with which it concluded formed the true prelude to Newton's _Principia_, and would alone suffice to establish the claim of Huygens to the highest rank among mechanical inventors.

The _watchman's_ or _tell-tale_ clock, used when it is desired to make sure of a watchman being on the spot and awake all the night, is a clock with a set of spikes, generally 48 or 96, sticking out all round the dial, and a handle somewhere in the case, by pulling which one of the spikes which is opposite to it, or to some lever connected with it is pressed in. This wheel of spikes is carried round with the hour-hand, which in these clocks is generally a twenty-four hour one. It is evident that every spike which is seen still sticking out in the morning indicates that at the particular time to which that spike belongs the watchman was not there to push it in--or at any rate, that he did not. At some other part of their circuit, the inner ends of the pins are carried over a roller or an inclined plane which pushes them out again ready for business the next night. The time at which workmen arrive at their work may be recorded by providing each of them with a numbered key with which he stamps his number on a moving tape, on which also the time is marked by a clock.

It is not desirable in clocks that the pinion wheels which are driven should have too few teeth, for this throws all the work on a pair of surfaces before the centres and is apt to produce a grinding motion. Theoretically the more leaves a pinion has the better. Pinions can be made with leaves of thin steel watch-spring. In this case quite small pinions can have 20 leaves or more. The teeth in the driving wheels then become mere notches for which great accuracy of shape is not necessary. Such wheels are easy to make and run well. Lantern pinions are also excellent and are much used in American clocks. They are easy to make in an ordinary lathe. The cog-wheels must, however, be specially shaped to fit them. They consist of a number of round pins arranged in a circle round the axis of the wheel and parallel to it. The ends are secured in flanges like the wires of a squirrel cage. The teeth of cog-wheels engage them and thus drive the wheel round. They were much used at one time but are now falling out of favour again. Entry: A
This kind of going barrel, however, is evidently not suited to the delicacy of an astronomical clock; and Harrison's going ratchet is now universally adopted in such clocks, and also in chronometers and watches for keeping the action of the train on the escapement during the winding. Fig. 25 (in which the same letters are used as in the corresponding parts of fig. 3) shows its construction. The click of the barrel-ratchet R is set upon another larger ratchet-wheel with its teeth pointing the opposite way, and its click rT is set in the clock frame. That ratchet is connected with the great wheel by a spring ss' pressing against the two pins s in the ratchet and s' in the wheel. When the weight is wound up (which is equivalent to taking it off), the click Tr prevents that ratchet from turning back or to the right; and as the spring ss' is kept by the weight in a state of tension equivalent to the weight itself it will drive the wheel to the left for a short distance, when its end s is held fast, with the same force as if that end was pulled forward by the weight; and as the great wheel has to move very little during the short time the clock is winding, the spring will keep the clock going long enough.

These old clocks had what is called a verge escapement, and a balance. The train of wheels ended with a crown wheel, that is, a wheel serrated with teeth like those of a saw, placed parallel with its axis (fig. 1). These teeth, D, engaged with pallets CB, CA, mounted on a verge or staff placed parallel to the face of the crown wheel. As the crown wheel was turned round the teeth pushed the pallets alternately until one or the other slid past a tooth, and thus let the crown wheel rotate. When one pallet had slipped over a tooth, the other pallet caught a corresponding tooth on the opposite side of the wheel. The verge was terminated by a balance rod placed at right angles to it with a ball at each end. It is evident that when the force of any tooth on the crown wheel began to act on a pallet, it communicated motion to the balance and thus caused it to rotate. This motion would of course be accelerated, not uniformly, but according to some law dependent on the shape of the teeth and pallets. When the motion had reached its maximum, the tooth slipped past the pallet. The other pallet now engaged another tooth on the opposite side of the wheel. The motion of the balls, however, went on and they continued to swing round, but this time they were opposed by the pressure of the tooth. For a time they overcame that pressure, and drove the tooth back, causing a recoil. As, however, every motion if subjected to an adverse acceleration (i.e. a retardation) must come to rest, the balls stopped, and then the tooth, which had been forced to recoil, advanced in its turn, and the swing was repeated. The arrangement was thus very like a huge watch balance wheel in which the driving weight acted in a very irregular manner, not only as a driving force, but also as a regulating spring. The going of such clocks was influenced greatly by friction and by the oil on the parts, and never could be satisfactory, for the time varied with every variation in the swing of the balls, and this again with every variation of the effective driving force.

Where or when the great and important step already conceived by Abu'l Hassan, and perhaps by others, of reckoning by _equal_ hours was generally adopted cannot now be determined. The history of gnomonics from the 13th to the beginning of the 16th century is almost a blank, and during that time the change took place. We can see, however, that the change would necessarily follow the introduction of clocks and other mechanical methods of measuring time; for, however imperfect these were, the hours they marked would be of the same length in summer and in winter, and the discrepancy between these equal hours and the temporary hours of the sun-dial would soon be too important to be overlooked. Now, we know that a balance clock was put up in the palace of Charles V. of France about the year 1370, and we may reasonably suppose that the new sun-dials came into general use during the 14th and 15th centuries.

Another class of subjects was now to engage his attention. The improvement of the telescope was justly regarded as a _sine qua non_ for the advancement of astronomical knowledge. But the difficulties interposed by spherical and chromatic aberration had arrested progress in that direction until, in 1655, Huygens, working with his brother Constantijn, hit upon a new method of grinding and polishing lenses. The immediate results of the clearer definition obtained were the detection of a satellite to Saturn (the sixth in order of distance from its primary), and the resolution into their true form of the abnormal appendages to that planet. Each discovery in turn was, according to the prevailing custom, announced to the learned world under the veil of an anagram--removed, in the case of the first, by the publication, early in 1656, of the little tract _De Saturni luna observatio nova_; but retained, as regards the second, until 1659, when in the _Systema Saturnium_ the varying appearances of the so-called "triple planet" were clearly explained as the phases of a ring inclined at an angle of 28° to the ecliptic. Huygens was also in 1656 the first effective observer of the Orion nebula; he delineated the bright region still known by his name, and detected the multiple character of its nuclear star. His application of the pendulum to regulate the movement of clocks sprang from his experience of the need for an exact measure of time in observing the heavens. The invention dates from 1656; on the 16th of June 1657 Huygens presented his first "pendulum-clock" to the states-general; and the _Horologium_, containing a description of the requisite mechanism, was published in 1658.

JOHNSON, THOMAS, English 18th-century wood-carver and furniture designer. Of excellent repute as a craftsman and an artist in wood, his original conceptions and his adaptations of other men's ideas were remarkable for their extreme flamboyance, and for the merciless manner in which he overloaded them with thin and meretricious ornament. Perhaps his most inept design is that for a table in which a duck or goose is displacing water that falls upon a mandarin, seated, with his head on one side, upon the rail below. No local school of Italian rococo ever produced more extravagant absurdities. His clocks bore scythes and hour-glasses and flashing sunbeams, together with whirls and convolutions and floriated adornments without end. On the other hand, he occasionally produced a mirror frame or a mantelpiece which was simple and dignified. The art of artistic plagiarism has never been so well understood or so dexterously practised as by the 18th-century designers of English furniture, and Johnson appears to have so far exceeded his contemporaries that he must be called a barefaced thief. The three leading "motives" of the time--Chinese, Gothic and Louis Quatorze--were mixed up in his work in the most amazing manner; and he was exceedingly fond of introducing human figures, animals, birds and fishes in highly incongruous places. He appears to have defended his enormities on the ground that "all men vary in opinion, and a fault in the eye of one may be a beauty in that of another; 'tis a duty incumbent on an author to endeavour at pleasing every taste." Johnson, who was in business at the "Golden Boy" in Grafton Street, Westminster, published a folio volume of _Designs for Picture Frames, Candelabra, Ceilings, &c._ (1758); and _One Hundred and Fifty New Designs_ (1761).
