THE STEAM ENGINE.

WITH ILLUSTRATIONS.

(Concluded from page 45.)

resume and conclude our remarks on the Steam Engine.
e explained the formation of steam and stated various facts
ng its power at different degrees of temperature. We have
lained and illustrated the application of that power in the
of WATTS' Double-Acting Condensing Steam Engine-
the four essential improvements in its construction for which
d is indebted to that great Inventor and Engineer.
will now add a few illustrations and statements for which
not room in our last number. To show more clearly the
on and working of the principal parts of the engine, we
e the following figure No. 1, which represents the boiler,
n-pipe, the cylinder and piston, the eduction-pipe, condenser,
P, &c.

Fis e lower steam-valve, and G is ́called the upper steam-valve. re opened and closed alternately by levers (L L, fig. 2) depressed by projections attached to the piston-rod of the K is the exhausting or eduction-pipe, having two branches es, like the steam-pipe, and the valves are opened and closed ame machinery. P is called the lower exhausting valve, e upper exhausting valve. By the eduction-pipe, through

these valves, the stean passes from the cylinder to the condenser as the piston ascends and descends.* L is the condenser, and O a stop-cock for the admission of cold water to promote the sudden condensation of steam from the cylinder. M is the air-pump, so called, because it removes from the condenser not only the water, but also the air, and he steam that escapos condensation. In fig. 2, (note,) F represents the air-pump, which conveys the water, &c., (heated by the steam) from the condenser into the hot-well I, whence it is conveyed by the hot-water pump K back to the boiler. R (fig. 1) is the safety valve. When the valves are all open, the steam issues freely from the boiler and circulates through all parts of the machine, expelling the air. This process is called blowing out, and is heard when a steamboat is about starting. In the working of the engine, the steam-valves F and G, and the exhaustingvalves P and Q are alternately opened and closed. When the valves F and Q are closed, and G. and P. opened, the steam from the boiler rushes at D into the upper part of the cylinder C, and presses down the piston H. At this moment, the levers (L L, fig. 2) attached to the pump-rod close the valves or stop-cocks G and P, and open F. and Q, when the steam flows into the cylinder at E, and rushes from above the piston through the eduction-pipe K into the condenser L. Thus, as the valves G. and P and F and Q are alternately opened and closed, the steam passing from the boiler drives the piston alternately upwards and downwards, thereby producing a regular and continued motion. The piston is connected with one end of a workingbeam by a rod called the piston-rod (see fig. 2), and the other end of the working-beam is connected with the machinery to be worked, the whole of which is moved by the motion of the piston. Thus an engine of great power is obtained.

It would exceed our limits and be foreign to our design to attempt a minute description of the various parts of the steam engine, much less to explain their construction; our object is to explain and illustrate to the general reader the principle on which the power of this wonderful machine is produced and applied, and to state some facts and phenomena connected with its operations. In the construction of the steam engine there is a relation between its different parts-for example, between the evaporating power of the boiler and the magnitude of the surface exposed to the action of

steam and eduction pipes are made in various forms, as also the valves: but the principle of action is the same in them all. For convenient on and reference, we here repeat the illustration, Fig. 2, which we gave in the last number :

WATT'S DOUBLE-ACTING CONDENSING STEAM ENGINE.

N. B. For a more full explanation of this figure, see the Journal of Education for March, page 45.

afety-valve R is connected with a lever whose fulcrum is at nd the weight at the other. The valve opens outwards, and is aperture in the boiler, so as to be steam tight. It is pressed a weight, the amount of which is regulated by the maximum which it is intended to limit the steam. Thus, if the valve be nch, and if it were intended to limit the steam to 20 lbs. per above the pressure of the atmosphere, the valve would be loaded ght of 20 lbs. Suppose the distance between the fulcrum and the e four times as great as the distance between the valve and ful

crum, it would require a weight of only 5 lbs. The weight is usually made to slide upon the lever (like the weight of a steelyard) so as to vary from time to time the limiting pressure of the steam. Instead of a weight, a spring steelyard, or spiral spring, is frequently used to determine the pressure on safety-valves. This is generally the case in locomotive engines. When the pressure of the steam within the boiler is greater than the weight on the safety-valve, the valve is raised up, and the steam rushes through the aperture under the valve, and thus removes the danger of bursting the boiler.

the condenser, &c. Engine builders allow from ten to eighteen square feet of heating surface in the evaporation of every cubic foot of water per hour; and within the same wide limits of from ten to eighteen square feet of heating surface in the boiler do engine-makers vary for every nominal horse-power of the engine. They also allow about 22 square inches of piston surface per nominal horse-power, the piston being supposed to move at the rate of 200 feet per second.* The evaporation of a cubic foot (or about ten gallons) of water, and the consumption of ten lbs. of bituminous coal per hour, are estimated for each horse-power of the engine. Some estimates, however, are half & cubic foot of water per hour for each horse-power of the engine. These variations in the estimates, or rather conjectures, of engine-makers show how little certainty has been attained in the constructions of the steam engine, and of how much improvement it is therefore susceptible.

The foregoing remarks relate to double-acting condensing steamengines. In steamboats the fly-wheel is generally dispensed withbeing superseded by the paddle-wheels; nor is there any coldwater cistern in marine steam engines, but the capacity of the condenser is increased to half that of the cylinder, instead of being one-fourth, as in engines for manufacturing purposes.

The Locomotive engine is a high-pressure steam-engine, mounted on wheels, commonly six wheels, and used for drawing loads on railroads, (and latterly on other level roads.) It is usually accompanied by a large wagon, called a tender, in which fuel and water, used by the engine are carried. We have heretofore stated that a high-pressure engine has no condenser, costs less, occupies less

complicated than the condensing steam engine high-pressure engine, after having moved the p the open air, and of course against the weigh the atmosphere. In the condensing steam en nearly a vacuum, is produced in the division or whose exhausting-valve opens the passage to th the piston, in ascending and descending, has 1 resistance of friction to overcome; but as no s duced in the cylinder of a high-pressure engine, additional resistance of the pressure of the atmo every time it ascends or descends. To overc requires a pressure of steam equal to that of the is 15 lbs per square inch; and the only part of which will be available as a moving power, is t it exceeds the pressure of the atmosphere. Hen engine, steam at a pressure of 10 lbs per squar effective mechanical force equal to that of stea 25 lbs per square inch in a non-condensing eng the latter, therefore, it is necessary to have stean pressure than in working the former. Hence t the low-pressure engine, and the latter the high is, of course, less danger in working the former less expenditure of fuel and water in proporti power obtained; but the high-pressure engine small, as well as comparatively cheap and simp is alone adapted to locomotion.

The boiler is closed on all sides, all its openings being guarded by valves. The apparatus of safety-valves and other appliances for the management of the power produced by this machine, are the same in principle, though differing in form, with those used in other steam engines, and are not represented in the above figure. The operation of the machine is as follows:-The steam is generated in great abundance in the boiler, and being unable to escape, acquires a high degree of elastic force-sometimes to the pressure of 40 or 100 lbs on a square inch. To put the engine in motion, the engineer opens the valve V by the handle L, when the steam rushing into the pipe S S S, passes in the direction of the arrow, and enters the valve-box at X. There a sliding valve, which moves at the same time with the machine, opens for the steam a communication successively with each end of the cylinder below. Thus, in the figure, the entrance on the right hand of the sliding-valve is repre

Portant Discovery in Voltaic Electricity.-Mr. ALFRED SMEE, -geon to the Bank of England, and inventor of the battery which bears me, has announced important discoveries in animal electricity. By which he terms electro voltaic, he has discovered that the terminations sensor nerves are positive poles of a voltaic circuit, whilst the musubstance is the negative pole. The sensor nerves are the telegraphs carry the sensation to the brain, and the motor nerves carry back the

which, upon theoretical grounds, he believes to be sufficient to account for all mental phenomena. Mr. SMEE has succeeded in making artificial elec. tric fish, and artificial muscular substance. Should these researches be fully confirmed by other investigators, they must be regarded as the most important physiological discovery of modern times.--(Jerrold's Weekly News.

Personal Appearance of Dumas and Lamartine.-The Paris correspondent of the N Y. Tribune says:-"I saw Dumas a few evenings since, sitting in a box at the Italian Opera. He is a liquid-eyed, voluptuous West Indian-with all the languid orientalism of a Creole in his mien. The luxurious appointment of the dress circle at the Italian, was a fitting frame for him. Opposite sat Lamartine, grave, sweet, and graceful. He looks older than his portraits generally make him. He is really 59 years old. His hair is grey-his head large, his brow grandly arched, and his eyes and nose of a generous greatness, finer than I find in the portraits. The mouth is large-he lips somewhat fallen, and it is here, about the mouth, that a faint feeling of vanity is visible. His manner is that of a man accustomed to homage-which was offered him this time, by a lady and two gentlemen who were in constant conversation with him. The party rose and left before the conclusion of the Opera""

Improvement in Locomotives.-JAMES S. FRENCH, Esq., of Virginia, has invented a plan by which locomotives, with cars attached, may be made to traverse a rail laid over the undulations of an ordinary road, without danger or difficulty. As the plan has not yet been made known to the public, we cannot judge of its practicability, but merely remark that the end desired is produced by an apparatus which gives the engineer power to control the adhesion of the wheels upon the rail, at pleasure; which was the difficulty to be overcome, and hitherto thought to be insurmountable. This has been a subject of study and experiment since the days of Sir Richard Philips, and if the above invention proves successful, it will be another important triumph of science, and an evidence of the rapid progress of the age.-[N. Y. Teachers' Advocate.

A New Application of Air.-A patent has lately been taken out in England, for an apparatus, by which the brakes of carriages are pressed against the wheels, by the expansive power of Air. The force is obtained by means of a piston, moved in a cylinder, either by air compressed in a reservoir, and allowed to escape suddenly through the valve against it, or from exhausting the cylinder of air behind the piston. In this way, it is said, a force is obtained of fifty pounds to a square inch. It seems to be altogether an ingenious affair, even in this age of novel inventions, and will undoubtedly be very useful for the purpose of suddenly checking the speed of the rail road carriages.-[Ibid.

To Transfer Engravings to White Paper.-Place the engravings for a few seconds over iodine vapor. Dip a slip of white paper in a weak solution of starch, and, when dry, in a weak solution of oil of vitriol. When dry lay the slip upon the engraving, and place them for a few minutes under a press. The engraving will thus be reproduced in all its delicacy and finish. The iodine has the property of fixing on the black parts, or the ink of the engraving, and not the white.-[Ibid.

The Manufadure of India Rubber Goods.-At Harlem, near New-York city, there is an India Rubber manufactory, where about one hundred and fifty women and fifty males are employed, and where military equipments are made in no small quantities. The raw rubber is first cleanly washed, and after being dried is ground between two large cylinders under an immense pressure, heated by steam, heated so hot that the rubber looks as though it were burning. While this is grinding, a preparation of turpentine is mixed with it to dissolve the rubber. The rubber comes from the roller a black mass, which is transferred to rollers of a still heavier pressure, where it is ground again under a strong heat; thence it goes to a third roller to be heated ready to be put upon the cloth; this is done by a powerful set of rollers. The rubber thus prepared is put upon the rollers and distributes itself evenly, at any thickness desired; the cloth is then put upon another roller that passes under the rubber, which, under great pressure, is forced into and through the cloth; no matter whether silk or the stoutest sail duck, it goes through. A coat is put on the other side in the same way, and no power can separate the mass after that. The cloth is then taken to the room where it is made into an infinite variety of goods to which it is adapted. These goods are cut out by patterns, and after the edges are covered with rubber cement, they are folded together and rubbed down closely, and soon become so closely fixed that any part will separate before the seams; there are in fact no seams; all is rubber, without a particle of other fastening. After they are all fastened, the whole article is covered with powdered sulphur and taken to be cured. This is done by placing them upon an iron railroad that passes into a large cylinder, where

which will outwear iron itself. The goods taken out of the heater are boiled in strong potash lye and then washed, which leaves them ready for sale. The sulphate of lead and sulphuric gases are also used to cure or vulcanize the rubber. The goods made by this machinery are elegant, and the operation of making them is very simple, and yet complete.

Gutta Percha.-The discovery of Gutta Percha promises to be one of the most important which has been made in the present century. Already articles of almost every variety, both useful and ornamental, have been manufactured from it. At the proceedings of the British Association, recorded in the Athenæum, No. 1086, a splendid communion dish and service were shown, composed of a preparation of this substance. The following is a list of some of the principal articles manufactured from it by the American Gutta Percha Company, whose office is at 139 William Street, in this city :-Machine bands, gas and water pipes, saddle and harness of all kinds, Trays, Fancy Boxes, Tables, Water-Proof Roofing, Inkstands, Drinking Cups, Boots and Shoes, Air-tight Coffins, Powder kegs, for the transportation of powder in water, Soda Fountains, Gasometers, &c. To a person unacquainted with the nature of this truly singular substance, it will appear incredible that so many articles as the above catalogue mentions, should be fabricated from a single material, but a visit to the above named establishment will convince them of its truth.

Gutta Percha is the concrete juice of a tree abounding in Borneo, and is obtained periodically by the Malays, by tapping the tree. Its introduction as a useful article of commerce is said to have been entirely accidental, and the first sample was transmitted to the Secretary of the British Association in 1843. The following is the manner in which it is prepared :-The rough and crude blocks of the substance are cut into slices and soaked in hot water. These are then placed in a mincing cylinder, and afterwards in a masticating machine, when they undergo the same process as the pulp of rags of which paper is made. It is then formed into sheets by being pressed through rollers. Out of these sheets are stamped driving bands for machinery, soles for shoes, boot-heels, and a multitude of other articles. This invention promises to be of very great ability in forming the sheaths for submarine telegraphs. But the most singular, and perhaps we may say important, purposes to which it has been applied is the construction of an acoustic telegraph, or, as it is called by its inventor, the Telakouhanon. This is a species of speaking trumpet, consisting of a long tube extending to any distance, at the pleasure of the maker; by means of which a whisper may be heard at the distance of three-fourths of a mile. In manufactories, hotels, and even in private houses, this will prove an invaluable acquisition since branch tubes may be affixed to convey the sound to any apartment in the building. In order to attract the attention of the person to whom the mission may be addressed, a whistle is attached at either end of the tube. An operator, who exhibited this curious instrument a short time since at London, placed one end of a tube of this description in the embochure of a flute, and blowing through the other end, by another person's adapting his fingers to the holes of the instrument, "God save the Queen" was played with perfect correctness.-[N. Y. Teachers' Advocate.

French Sewing Machine.-This machine, to which we have before alluded, is the invention of an humble artisan, who has a great mechanical genius, and who has been engaged for thirty years in the perfection of his invention. He received a patent for it in France a few years ago, and it is said that for more than twenty-five years, he sought in vain to make it work, and that the thought flashed all at once upon his mind regarding its true and perfect principle. The machine was introduced into London some time last year, and has attracted much attention in that city. It is very cheap; some are sold for twenty dollars, and the price varies from that to thirty. The machine is fixed on a table, and is a very small box. It is worked by a treadle, and every movement of the foot produces a corresponding action in the needle; so that three hundred stitches can easily be made in a minute. The hands are merely used to guide the material being sewn, and by turning a screw, the stitch is easily varied. The machine will sew, stitch, and forms cords and plaits. The stitch is the tambour or crotchet stitch. The whole value of the invention consists in making machinery to do what was hitherto done by the fingers, and thus resolving a problem supposed impracticable. The beauty of this machine is, that it can work button holes and embroider. M. Magnen, who exhibited in London, wore an entire suit worked by it, consisting of coat, pants, vest and all their appurtances. To France belongs the credit of this invention. M. Thimonnier is the name of the inventor, and his fame will go down to posterity with that of Jacquard.

Mr. Halt, sent him to Hartford; but fi sent him to Dr. Chaplin, of Cambridge, Mass. The was no relief for him at that time,-but at the age of there would be a change; that the brain was too much cranium, and there would at that age be a contraction, w it to act healthfully. His anxious father saw their hopes red for nineteen years. That time has recently expired, joy the prophecy is fulfilled. The man began to inquire if he had just laid them down, and resumed his mathemat he left them. There was no trace on his mind of this lon or of anything which has occurred in it, and he did not k almost forty years of age.

The departments of School Architecture and Science, illustrated as they are with wood engravings, are as well cal culated to afford instruction as they are to awaken interest. The increased expense incurred in suitably illustrating the work, evinces the disposition of its Conductors to make the Journal all that its best friends and supporters could desire it to be, while at the same time it furnishes an additional claim upon the patronage of the public.

From the St. Catherines Journal.

The number for March has reached us, and we must say that it seems to be an improvement on even its own predecessors. The work is really invaluable, and we entertain large expectations from its circulation. We would add to the testimony of other Districts, as given in this number, that of the Niagara District, as far as we have the means of knowing it, that a growing feeling exists in favor of the " Free-school system. The only objection ever made to it in this part of the country came from a few individuals, whose argument was "We have paid for the education of our own children, and now let others do the same." On investigation this argument was found to be based on falsehood; consequently, it lost all its force, if ever it had any. The children of these objectors are educated at our public Grammar Schools, and at the Colleges, sustained and endowed by the public property. They had their children taught at the expense of the country, quite as much as the poor man who sends his children to a Common School. We can assure the conductors of the Journal, that at this moment the existence of a rate-bill keeps two thirds of the children of this large population away from school altogether. In this state of things, we must and do look for an alteration, if the blessings of education shall be commensurate with the wants and interests of a growing community. Every narrow minced and merely selfish consideration must give way before the wants and interests of the country.

From the British Colonist.

The "Journal of Education" for March, was laid on our table yesterday. Its contents are valuable, and deserving of general perusal by all who take an interest in the important questions so ably discussed in the "Journal of Education," and who re desirous of acquiriug sound information respecting them. The subject of School Architecture is followed up, by the continuation of the very able paper on School Architecture, by the Hon. HENRY BARNARD, State Commissioner of Public Schools, Connecticut and Rhode Island," Among the other articles in the number before us, we have pleasure in particularly referring to one, by II. Y. HIND, Esq., Mathematical Master in the Normal School for Upper Canada, on Schools of Art or Practical Knowledge," to which is appended a synopsis of the course of study pursued in a School of Art and Design. Under the head of" Science and Practical Arts," there is an interesting paper on the Steam Engine, with illustrations, Altogether, the number of the "Journal of Education" before us, is fully equal, in point of merit and worth, to those which have preceded it, if it does not surpass them, and we cordially endorse the appeal of the Editor, wherein he expresses his " earnest hope that the favorable opinions expressed by correspondents and others, in different parts of the Province, respecting the "Journal of Education," will be followed by corresponding exertions to increase its circulation as widely as possible."

From the Philipsburgh Gleaner, L. C.

The second number of the U. C. Journal of Education has reached us. It contains an admirable Lecture by Dr. RYERSON, to which we shall refer in a future number. Every Clergyman-School Commissioner, and Teacher, ought to take the Journal.

us.

The March number of this excellent periodical is before It is embellished with a view of the "Front Elevation of one of a series of School houses, [including restdence for teachers] recommended by Her Majesty's Privy Council Committee on Education." We cordially comthend the work to the patronage of all who feel interested in the education of the youth of this Province.

From the Perth Constitutional.

The "Journal of Education for Upper Canada," is marching on in the laudable career of usefulness and efficiency. Men of education may err, but the history of every country and people informs us, that though the ferocious bravery of a nation might extend their limits beyond conquest, it is only by the arts of civilization and intelligence, that the belligerent spirit of our nature is deprived of its rudeness, and the energy which, without education, would be employed to destroy, is, under the star-eyed guidance of a liberal education, ma e the means of diffusing any blessings.

From La Minerve.

Nous avous reçu la livraison de mars du "Journal d'Education" potir le Haut-Canada. La rédaction en est toujours conduite une rare habileté. Ce journal est véritablement ce qu'il doit être, une excellente école.

From the Montreal Witness.

The Superintendent of Education for Canada West is doing a great work with his characteristic zeal and ability. The work is to render popular an elevated standard of education, with all its adjuncts of good teachers, and good school houses throughout the Province, and one of his great levers to accomplish it, is the Journal of Education The March number of this periodical is before us, embellished with a front elevation of a model school-house, and filled with articles admirably adapted to raise up a strong and enlightened public sentiment in favour of good popular education.

This Journal should, we think, be widely circulated and we scarcely know any way in which an association, say of young men, in each county of Canada, could more effectually promote the general interests of the country, than by raising funds to send the Journal of Education to each Minister, Member of Parliament, District Councillor, Magistrate, and School Teacher in the county in question. If associations would set seriously about such a work, we doubt not that Dr. RYERSON would take care to have the necessary number of copies furnished at a very cheap rate, in order to facilitate the advancement of the cause, which he evidently has so much at heart.
