A Large Shearing Machine. Messrs. Buckton & Company, of Leeds, England, have long been celebrated for ex- cellent design and workmanship in their | tools, a noticeable feature in their machine tools being the adoption of frames and beds | go constructed as to make the machines independent of their foundations. In former days the satisfactory working of a machine tool, especially if of large size, de- pended very much on the foundations and the care with which the several parts were attached to these and walls, and in some eases roof beams also. Owing to the adop- tion of the method above men- tioned, this is now seldom nec- essary, and machines are tested before sending them out by connecting them by a strap to the shafting of the works, or by means of the small special engine attached to the machine itself. The large shearing ma- chine turned out by the above firm, and of which we present an engraving this week, is a good example of this class of design. The machine will cut steel or iron plates cold up to 1%-inch thick 26 inches from the edge ; it has 11 feet face of knife ; a plate 8 feet wide will go clear through the ma- chine, and can be cut across at any part of its length at a sin- gle stroke. The moving shear slide is balanced with a coun- terweight and fitted with a stop motion, so that while the engine, fly-wheel and gearing may run continuously, the ac- tion of the shear can be stop- ped until the plate is put into ition, when the two stop locks are slid by a coupled motion simultaneously into their places, and the slide is peut down by a parallel motion, being acted upon at its two extremities by connect- ing rods driven by parallel ec- centric pins on the two ends of the main shaft. All the wheels in this machine are cast with split bosses, planed at the pints and hooped’ with wrought-iron rings. There are two overhung wheels about the machine ; they each work be- tween a pair of brass bearings, in which any wear that takes place does not prevent the teeth from still bedding fairly across the faces. The main eccentric shaft is of wrought iron, 20 inches diameter, and works in solid brass bushes, each 18 inches long. At each stroke of this machine it overcomes a resistance in the plate of about 4000 tons of breaking load. The whole ma- chine, with engine complete, is so self-contained that steam has been pat into the cylinder at the makers’ works, just as it stands depicted, on the floor, and a plate of the maximum dimensions cut into slabs with repeated strokes of the ma- hine, A machine of similar design, but for plates 14 inches thick, s now in course of construc- tion at these works, and one of the size described is in opera- tion at the works of the Bowl- ing Iron Company, near Brad- ford, England. Among other notable machines in course of construction at Messrs. Buck- ton & Co.’s works is a very large planing machine, to plane 12 feet 6 inches wide, and carry «casting weighing 30 tons, and alarge lathe to take in a 14- foot wheel or a heavy shaft. The bed is 45 feet long and is made in two parts, the joint being of about double the depth of the other part of the bed so as to secure perfect rigidity. — —— = The New York Postmaster tas adopted an improved ethod for sealing securely the as was expended for cleaning the others, viz., $1.25 a thousand. = a — Automatic Sprinklers. Some very remarkable instances of the value of automatic sprinklers have recently come to our notice. The first one was in the mills of the Bates Manufacturing Co., at Lew- iston, Maine, where a watchman on the 20th of June discovered, late at night, a fire in some dyed cotton, which was in the process of drying. A Parmelee automatic sprinkler was at work at the time. Of course the agent was called immediately and took a ! the most severe tests to which this kind of apparatus has ever been subjected. Another instance occurred at Amesbury, Mass. A fire was discovered at night, during the present month, by a watchman in opening a room in one of the mills in which 100 bales of loose cotton had been opened the day previous. These were on fire from an unknown cause, probably oil absorbed by the cotton when in the bale. The fire took on the apron of the opener. A Bishop automatic sprinkler head had started. The force of the water was so great that the inner cap was | burst so that a %-inch stream was moder- ately distributed by the irregular edges of ! facturing buildings with such sprinklers, and! for which it js intended : an Wii ATMA Nii iy im hy UN \ ii h MN ie I Le iii i fue ‘il | Mh caught it up and threw it out of the window. | ered that even the stage carpenters would The loose cotton was scarcely injured. burrowing fire and the water were in opera- tion together about half an hour. The total damage was only $100. This prompt protec- tion by a stream of water delivered directly upon the fire and nowhere else, is one of the great features of the automatic sprinkler system. For economy of water and effective- ness of distribution it is by far the best and most perfect system thut has yet been in- vented. Itsadvantages are greater than those of astream from an engine, and it would seem | copper and tin | Se., astudent of Rutgers College, N. J., The | no longer have anxiety in regard to fire.

It is said that this was one of The up- | the broken cap. This was sufficient to ex- | oe the fire, with the exception of the | embers of the apron slats. In this case, al- | though the fire apparatus of the mill was | prepared for use, it was not needed, and the damage was not sufficient to warrant a call | upon the insurance companies to make good. | Perhaps the most remarkable case, certainly | one of the most difficult to be put out by ordinary means, occurred recently when a waste gatherer brought clean card waste into the opening room where 100 bales ready for | mixing were piled up. The pile of waste | was about 20 feet long, 8 feet high and 3 feet | wide. It was 3 feet distant from the loose | cotton. Probably a match had been dropped upon the floor by which the waste was igni- | ted. The fire of course flashed over the sur- | face instantly. The Burritt automatic sprink- lers overhead operated so quickly as to cover and protect the whole pile, and while the fire was burrowing in the waste the employees to arrange if necessary to have fire engines, steam pumps and other fire apparatus de- liver their water directly into the sprinkler pipes. After what we have said in regard to the extinguishment of fires in loose cotton by au- tomatic sprinklers, we think there is no fur- ther excuse for fires in theaters. If a pile of loose cotton, over which the flame will run like a flash of lightning, can be set on fire and then extinguished almost instantly by sprinklers, certainly there is no reason why theater fires should not be extinguished in the same manner and with equal certainty. The scenery employed is infinitely less combusti- ble and more difficult of ignition. The stage opening, if defended by automatics, might low volumes of smoke to pass, but certainly no fame could ever reach the auditorium to do any damage. In the same way every line of scenery and all the maze of cordage be- hind the scenes ceuld be se thoreughly eev- ' sometimes lead, zine, gold and silver are added with the intention of giving it greater brilliancy of fusibility. Modern bronzes differ from the antique ones in composition and manner of manufacture. The bronze coin of Alexander the Great (335 B. C.) contained 86.72 per cent. of copper, and 13.14 por cent. of tin. A Ro man bronze coin (500 B. C.) contained 66.04 per cent. of copper, 7.66 per cent. of tin, and 29.32 per cent. of lead Many of the modern French bronzes are composed of : Copper, gI parts ; tin 2 parts ; zinc, 6 parts; lead, 1 part. The Japanese word corres- ponding to bronze is ‘‘ kara- kane,” meaning Chinese metal Brass is called ‘‘ shin-chu.” The bronze industry in Japan is very ancient. Copper has been produced in Japan since the eighth century, but even before that period the manu facture of bronze had reached a certain stage of perfection, the copper or its alloys having been imported from China. Giyoka, a priest, and the in- troducer of the potter’s wheel, planned the erection of mon ster statues to the god Buddha, and the plan was carried into execution by the Emperor Shomw, in 724-749 A. D. Three of these statues still ex ist. They are about 50 feet in hight, and are said to contain a small percentage of gold The modern bronze castings are employed for many useful and ornamental purposes, such as statues, bells, vases, knife sheaths, candlesticks, <&c., and are generally made in the simple and curious styles of the old and celebrated Chinese bronzes, or are embellished with the characteristically gro- tesque vagaries of Japanese art. The bronze cast in clay molds, formed upon models made of a mixture of wax and rosin, which is melted and poured out of the mold previous to running tho metal in. The melting fur- naces are generally of small dimensions, and consist of an iron pot lined with clay. The surface of the casting is then finished and the design cor rected by chiseling Ire quently gold and silver are in laid to produce artistic effects. This work is known as * zo and is principally car ried on in the provinces of object $3 are ran ?? gan, Kagan and Techin.

THOMPSON’S PATENT FOR Wet Pulverization of Rocks, Ores, Rolling Mill Fix AND OTHER MATERIAL, EITHER COARSE OR TO AN IMPALPABLE POWDER. STEPHEN P. LLL AL LE 2 P| LLAMA LERAARL LAE VIGSSIVIISIINGE M. TASKER, Since Mr. Edison’s invention of the micro- yt .simeter which proved so sensitive to heat, jsutisfactory instruments for the measure- ment of extremely delicate changes of tem- perature have not been brought out. M. Michelson, of Paris, however, recently ex- hibited before the French Physical Society an apparatus in its experimental form which appears to satisfy all the requirements. The apparatus is based on the principle of bi- metallic thermometers, ebonite or hard rub- ber being chosen instead of one of the metals. Hard rubber is 10 times more dilatable than platinum when exposed to heat, and a spring composed of platinum on one side and ebonite on the other will curve under the least in crea;e of temperature. At the extremity of the spring is fixed a small glass stem form ing an elbowed lever which rests against a small mirror suspended by a silk fiber. When the spring curves or straightens, as the case may be, the mirror is deflected, and a ray of light from a lamp reflected from its surface upon a scale moves up or down the divisions of the same. sy giving to the spring and lever a relatively great length, the instrument can be made exceedingly sensitive, and the inventor expects to be able to measure the thousandth of a degree cen- tigrade. An Improved Gas Engine. Mr. Christian Rohn, of Worcester, Mass., has, after repeated experiments, succeeded in designing a gas engine, of which we ap pend the following particulars: The engine is double-acting and very simple in construc tion, and the obstacies which have usually seriously interfered with the construction of double-acting gas engines have been success- fully overcome. The valves are driven by eccentrics, and the friction of the several moving parts has been reduced to an ex- tremely low figure. The mixture of gas and air is compressed to some extent before being admitted to the cylinders, or only sufficient to make it fill the cylinder in the time re- quired. This gas engine, it is said, can, with-safety, be made of any size up to 100% horse-power, making it a three-cylinder en gine and using steel in its construction. Mr. Rohn has also designed another gas engine of the disk-engine principle, having six cyl- inders, and as the charge for each cylinder is exploded in succession once in every revo- lution of the engine, great regularity and uniformity in power and speed is expected. Tires of Mixed Metals. The Saint Chamond Works have recently commenced the manufacture of tires of - mixed metals, half iron and half steel, and which, it is claimed, will have a hardness of the latter without its fragility. The body of the tire is composed of a ring made of pieces of puddled steel, and inserted between two hoops of fine iron which form the outer sides of the section, the whole being welded to- gether by means of the hammer. The prin- ciples of this manufacture are as follows : A bar of fine iron, which is to serve as the core, is first rolled, and then a hoop of fine iron is put on at each end cold. One of these hoops is afterward to form the flange, and is composed of three coils of equal size. The other is formed of a single coil, and is to make the outer face of the tire. Wedges of puddled steel are then placed obliquely in the space between the two hoops, thus mak- ing so many spirals inclined on the axis of the tire. This arrangement brings the wedges together when the hammer is ap- plied, and thus a complete welding is ob- tained. The wedges are cut from rolled bars ; they should be of hard steel, but yet soft enough to weld easily with fine iron. The round pieces thus obtained are forged and welded with the hammer. Four heats are requisite to obtain a ring like those used in the ordinary processes. The welding is completed by the rolling, and it brings the inside core to such a small thickness that it disappears altogether in the boring. Standard Measurements, The following paper by Mr.Geo. M. Bond, of the Pratt & Whitney Company, was read before the Hartford meeting of the Ameri can Society of Mechanical Engineers : The subject of standard measurements is not a new one, though it has received the atten- tion of minds well qualified to master it; still, the lack of a definite system of uniform sizes for general use, especially in machine construction, led to the appointing of a committee by the Master Car Builders’ Asso- ciation to select some one prominent firm en- gaged in tool making, to undertake to fur- nish standard United States, or ‘* Franklin Institute” thread-screw gauges. The choice fell to the Pratt & Whitney Company, of Hartford, Conn., and in order to commence aright, the services of Prof. W. A. Rogers, of Harvard College Observatory, Cambridge, were enlisted for the purpose of obtaining an exact transfer from the British lmperial Yard, thus enabling the company to feel as- sured that the ‘* bottom ”’’ had been reached, and todo, once for all, and for the benefit of all, what seemed absolutely necessary for a correct beginning. The necessities growing out of the difficulties of subdividing the yard, and of applying such subdivisions in practice, led to the construction by them of a com- parator, of the form which Professor Rogers found best adapted to comparison of stand- irds. Two of these comparators, or ‘‘ meas- uring machines,” have been made ; one to be placed in position at Harvard College, and the other to remain atthe works of the com- pany for use in future comparisons. It is not the intention in the present paper to vive an exhaustive report, or a detailed ac- count of the condition, at this late day, of the question of standards of length, but simply to furnish, in a brief and general way, such faets and statements regarding the subject as are of importance to those in- terested in the adoption of a uniform stand- ard of size in the manufacture of tools, and machinery requiring interchangeability of parts, and to show in what the standard for he basis of future measurements consists, and the method adopted for determining how closely in practice such standard meas- urements may beapplied. As is well known, three natural units have been proposed as the basis of standards of length, as follows: 1. The length of a pendulum beating sec- onds in a vacuum, at the level of the sea, in the latitude of London. 2. One ten-millionth part of the quadrant of the earth’s circumference. 3. The length of a wave-length of given refrangibility. The first of these natural units was found to be unsuitable for the accurate restoration f the original British Yard, rendered useless by the great fire October 16th, 1834, which destroyed both houses of Parliament, where the standard had been kept. Sir Francis Baily, Bessel, Kater and Dr. Young found serious errors affecting the comparisons originally made between the bar marked ‘* Standard, 1760,” and the exact length of a pendulum beating seconds under the above conditions. It may be interesting to here insert the act legalizing the standard : ‘* Section 1. Be it enacted .... that from and after the first day of May, one thousand eight hundred and twenty-five, the straight line or distance between the centers of the two points in the gold studs in the straight brass rod, now in the custody of the clerk of the House of Commons, whereon the words and figures ‘‘Standard Yard, 1760,” are engraved, shall be, and the same is here- by declared to be, the original and genuine standard of that measure of length or lineal extension called a Yard; and that the same straight line or distance between the centers of the said two points in the said gold studs, in the said brass rod, the brass being at the temperature of sixty-two degrees Fahren- 7 SOLE MANUFACY heit’s thermometer, shall be, and is hereby 7 CLURER, Automatic Indicator for Determining denominated the Imperial Standard Yard. by Meridian Time, * * * * Care of MORRI = S; TASKER & CO., Limited, There was recently exhibited in the window \ fe ae 2, And wngreee ete us - . e 1 Sai . the said Standar« ard, 1 ost, destroyec PHILADELPH i _ | of Messrs.

A magnetic bar moves freely on a pivot at the pole, and a small piece of wire crosses the bar at both ends. In places where the magnetic and terrestrial meridian coin- cide, the shadow of the bar on its pivot will indicate solar or apparent noon, and the shadow of the wire on the south end of the bar falling on the meridian at noon, will limit acertain arc of the meridian between the shadow and the equator. When the sun’s declination is south, this are will be equal to the latitude of the place minus the declina- tion. Therefore, when the sun’s declination is known, the latitude of the place may be found by a meridian observation of the dial ; and, when the latitude of the place is known, the sun’s declination may be found by a sim- ilar observation.” The inventor claims that | the moon’s meridian may also be taken with | the instrument, is always adjusted for use, inches, and one thousand three hundred and ninety-three ten-thousandths parts of an inch. “‘Be it therefore enacted and declared, that if at any time hereafter, the said Im- perial Standard Yard shall be lost, or in any manner destroyed, defaced, or otherwise in- jured, it shall and may be restored by mak ing a new Standard Yard, bearing the same proportion to such pendulum as afore said as the said Imperial Standard Yard bears to such pendulum.” In view, therefore, of the errors due to the doubtful reductions of the level of the se a, | and the estimated specific gravit y of the pen dulum employed, and elso to other important factors, shown conclusively by Dr. Young, Kater, Bessel and Baily to be unreliable, the method adopted and employed in restor- ing the Imperial Yard, was to use standards ive : and that it is of advantage in cases where which had previously been prepared with it.
