There is, perhaps, no recent mechanical provement attracting so much attention at » present time among steam engineers as , Joy valve gear, accounts of which have iched this country from the foreign tech- cal press. Some of these descriptions have ,en republished in American technical jour- als, The success of the Webb compound loco- otive, in which this gear formed a prominent -re, attracted a great deal of attention on th sides of the water at the time of its trial. o adequate description, however, so far as r information goes, has yet been presented, therefore, engineers and mechanics nerally are somewhat in the dark as to the erits of the improvement. Mr. Joy is at esent in this country for the purpose of in- oducing his invention and explaining to ‘ineers the peculiarities of his valve gear. t the meeting of the Master Mechanics’ ssociation, held at Niagara Falls last k, Mr. Joy read a paper upon this ject, and also distributed «a number ’ illustrated circulars relating to his inven- . Some of the illustrations prepared \ir. Joy for this purpose, will be found ag the engravings on this and the follow- pages. We have prepared additional cuts order to make our readers thoroughly ailiar with the improvement, and expect resent in another issue a full report of » paper above referred to. The action of this gear is such that the int of cut-off for the live steam may be ied to give the required degree of expan- ,, without incurring the evils common to » link motion, of varying the amount of lve lead and of steam compression. These vantages are preserved during both piston okes with the engine running in either di- tion. By this means there is obtained a ‘ribution of steam that has long been ght for by inventors. The manner of omplishing these ends is shown in the ompanying engravings, which represent ious applications of the gear. The action the various mechanical parts, however, * perhaps be best explained by reference gs. 1 and 4, which represent different .ods of applications of the gear, but in th letters of reference correspand. Mo- for the valve gear is taken from a point he connecting rod, the lever B being ved at A, while at H it is connected to rod C, which is pivoted at its other To B is connected the end of a lever or 2 E, which is pivoted at F toa pin which ries the slide blocks or dies, f, fitting in a deway, T,in Z. At end b lever E is con- sted to the valve spindle G. It is obvi- s that the vibration of E upon its center F , supposing the sliding block remains sta- buary, move the valve spindle G. The eway of Z, in which blocks / slide, are, hen Z is at its vertical or mid position, an of a circle, of which the axis of the pivot (Fig. 1) is the center. Hence if E of Fig. were disconnected from B (by removing pin at D), moving the pivot F and sliding r block f up or down in the slideway Z would not impart any motion to G. |the motion, therefore, that is given to G ben Z is in its mid ition (standing verti- ly) is that due to the vibration of E upon e pivot F. But the motion of G, and there- ¢ the travel of the valve, may be increased causing the slideway in Z to stand out of the ical position as it is shown in Fig. 5 at X. is obvious that if f were moved up the eway in Z until the axis of its pivot came the dot at h and then down the slideway til that axis stood at g, there would given to fa certain amount of lateral mo- n, which would be determined by the bount of inclination of Z. Here then isa ans of increasing the lateral motion of F, i therefore of the valve, by moving Z so t it stands inclined or out of its vertical mid position. By varying the valve vel the point of cut-off, and therefore the sree of expansion, is varied. In moving ut of the vertical to the position shown at Fig. 5, however, the valve stem, and refore the valve, will be moved to the bt, causing steam to be admitted to the ‘t nearest to the crank. But if Z be ved so that its slideway inclines to the left, port furthest from the crank will be ied ; hence the forward or backward mo- of the engine is governed by the direc- of inclination of Z, while the degree of ‘mclination governs, to a certain extent, travel of the valve, and therefore the cunt to which the steam is used expan- &y. When Z is in mid position the valve ‘elis such that the port opening for live AL . equal to the amount of lead given to Valve, ¢ may now explain the construction of Parts as follows: In the method of ap- tion shown in Fig. 4 there are two of tides Z, which are secured together by a *Y, the inner side of said yoke being ted to the shaft L, which is operated in jurnal bearings by the arm M, in the “manner. The yoke Y is provided with ual bearing at its outer end in a stay-rod ded for that purpose. The advantages Us gear compared with the link gear are & by the inventor as follows:: lt is simpler and less costly than the Fvear by fully 25 per cent., taking the forms of application in both. A com- n of the two shows a saving in weight Xt amount. The saving is not only in it, however, but also in the greater sim- 2. The gear is more correct than the link | motion. By setting out the center lines prop- erly, a valve-path diagram is given in which the lead and cut-off are exactly equal for both ends of the cylinder, and they remain so in all grades of expansion to mid-gear ; and when the port opens and closes by the amount given as lead at equal distances in each side of the center line. ° . ° ! 5. The motion of the valve is not, as in the link motion, limited by a given throw of eccentrics, but as the reversing depends on the angle to which the links Z are inclined, it is only necessary to carry them over a slight amount beyond the usual full gear, or, say, 75 per cent. cut-off, to give an extended opening to the port, which may be carried as | far as to allow steam on the piston for go per New York, Thursday, June 29, 1882. 2 shows the application of the Joy valve gear to a marine engine, and _ illustrates the difference in space occupied between engines equipped in the old and the new way.

The valve is opened more rapidly, the | cut-off is more prompt, and the exhaust port is opened more quickly than with a link- motion. 4.

Hence, wherever an en- | gine might erase to stand it would never be necessary to back it to get away with a , train. It would only be necessary to push over the lever, giving a little extra angle to the links Z, and, as stated, the action of the n outside cylinder | under the direct inspection of the engineer, | steam would be prolonged on the piston to | “ous point. val, B to C, in the down stroke, the center F of the lever is continuing to swing down the inclined arc, but the lever E itself has begun to take action as a lever, and this action is counter to and partially neutralizes the move- ment of the center F. The result is a longer dwell of the valve at the time when it is fully opened. During the next interval, while the crank passes from C to D, the movement of the center, F,is almost nothing, while the lever action of E is fully developed, and its reaction is at the quickest. During this time the valve is being closed. In the next inter- val, D to E, when the valve is closed, the lever action of E continues, though its effect gradually decreases, while its center, F, is now swinging up the inclined arc Both are acting in the same direction, but as one diminishes while the other in- creases, the result is to maintain the speed of the valve nearly constant until approach- ing the point E, when a considerable accel- eration takes place by the center F swing- ing more rapidly up the inclined arc. This occurs just at the point required for the release, which is thus affected by a quick opening of the exhaust port as it is uncov- ered by the inner edge of the valve, giving a round, full curve in the release diagram. For the upward stroke the same action is repeated which has just been described for the downward one. The Joy valve gear is at present attract- ing attention both in this country and abroad, and its advantages over the old gear will probably soon be more generally recognized and appreciated in engineering circles, em SCIENTIFIC AND TECHNICAL. THE HOLDING POWER OF BRASS TUBES IN TUBE PLATES. A number of experiments made by Mr. W. H. Shock, U. 8S. N., on the holding power of brass tubes in tube plates, have given results worthy of attention. Forty- eight experiments were made with brass tubes, 9 in. area in cross section, tubes with screwed ends, having a sectional area of 1.33 inches, The average resistances ob- tained with each method of tube-fixing be- fore the tubes were withdrawn from the plate was as follows: No. 1, tubes simply tightened with the expander, 6700 pounds ; No. 2, expanded and beaded over, 16,829 unds; No. 3, expanded, ferruled and eaded over, 31,751 pounds; No. 4, ex- panded, and ends screwed into -inch nuts, pera gins cay No, 5, expanded, and ends screwed into -inch nuts, and ferruled in addition, 39,935 pounds. In 75 per cent. of the tests the plate representing the tube plate was 34 inch thick, and the rest 4% inch and % inch thick. It appears, then, that where the tubes were beaded over and fer- ruled, the variations of thickness of tube plate from % inch to % inch did not increase the holding power. The holding power of tubes simply fixed by the expander, and neither beaded over nor ferruled, is generally very much beyond any strain that would be put upon them by the working pressure of a locomotive boiler. THE DETERMINATION OF NITRIC ACID IN SOILS. At a recent meeting of the Chemical So- ciety, England, a paper was read on the above subject, from which it appears to be important to sample the subsoil as well as the surface, and to take the samples after dry weather. Boussingault found many years ago that after dry weather the surface soil of a kitchen garden contained nitrogen as nitrates = 29.2 per million ; a few weeks later, rain having fallen, the nitrogen amounted to 1.2 per million. Experiments made still later, after dry weather, gave the quantity of nitrogen as 41.3 per million, It is necessary to dry the sample speedily, else nitrification proceeds; drying at 100° may occasion a loss of nitrates in proportion to the wetness and mass of the soil and ite rich- ness in organic matter. Drying at a high temperature also greatly increases the solu- ble organic matter in a soil. The plan adopted by Mr. Warington, the author of the paper above mentioned, is to break up the soil in small pieces, place these in paper trays, and dry in a stove at 55°—the tem- perature at which nitrifaction is said to cease. Soils thoroughly dried in dry air seem to uudergo very little anes by keep- ing. The method commonly used to prepare an extract of the soil is to eles 500 or 1000 of soil with its own, or twice its own, weight of water, and take a known portion of the solution for analysis. & NEW WATER ELEVATOR. Among the many interesting exhibits at the recent Naval and Submarine Exhibition, England, was a new water elevator, by means of which, it is stated, from 300 to 375 valve in a different form from that we have | gailons of water can be raised per minute, described, also applied to a marine engine. In this a radius rod is used in place of the slide and slideway above mentioned, Fig. 6 shows the path of crank of the engine illus- | trated in Fig. 3, divided into eight spaces. The action of the gear may be described in connection with this diagram es follows: | the consumption of fuel being from 8 to 10 | ewt. of slack per day, and the discharge pipe being 6 inches in diameter. The apparatus consists of a cylindrical chamber furnished at the lower end with inlet and outlet valves for water, and at the upper end with an in- let valve for air, while, in addition, there is ferring to the other engravings, Fig.| While the crank is passing its top center | a small steam valve which is opened periodis SS...

Partial condensation of the steam then takes place, and a fresh charge of water is taken in, while, at the same time, air enters through the air-inlet valve, the air so ad- mitted appearing to form a kind of cushion between the water and the steam, and ap- pearing to prevent condensation of the latter during the greater part of the delivery stroke. The entire arrangement is charac- terized by great simplicity, and further im provements which, it is said, will shortly be made, will render the apparatus still more economical and efficient. SOUNDS PRODUCED BY THE EFFECTS OF JETS ON DIAPHRAGMS. It was discovered in 1826 by a French en- | gineer that when a plate was held normal to the axis of a jet issuing from an orifice under pressure, and at a certain hight above the jet, it was repelled, whereas if held lower it was attracted. It was also found that there was a neutral point at which the A NEW FORM OF BIOHROMATE CELL. A new arrangement of the well-known bichromate of potash battery has been pro- posed by Mr. F. Higgins, of the Exchange Telegraph Company, London, which, besides yielding very powerful currents, is said to be very econom cal, inasmuch as the waste liquor of other bichromate batteries and the scraps of zine left by the wasted zinc plates may be successfully utilized. The cell con- sists of an earthenware jar fitted with an overflow spout near the mouth, the scrap placed in a pool of mercury at the bottom of the apparatus. A copper wire insulated with gutta-percha, except at the foot, where it enters the amalgam of zine and mercury, passes down the middle of the jar. Two carbon plates, arranged parallel to each other, are suspended from the mouth of the cell by a frame, and connected with an electrode A battery of be arranged by placing each below the one above it on a suit- so that the overflow of liquor zine being each ther b these cells ma one a little able platform, from one cel! may run into the next, thus causin ¢ a continual circulation of the wasted The Joy Valve Gear.—Fig. 4.—Illustration of the Princtple of Action. plate was supported on the jet, and emitted an audible note as it oscillated about this position of equilibrium. It may not be with- out interest in this connection to state that M. Th. Vautier has recently succeeded in evoking very high sounds in this manner and registering them. having a pressure in the boiler of 414 atmos- pheres, and issuing from an orifice about I inch in diameter, against a plate 4 inchin diameter and .06 inch thick, held .007 inch from the orifice, a sharp note was obtained, the number of vibrations per second being about 7250. SAFETY LAMPS. It is a well-known fact that when a light is covered by wire gauze, as in a safety lamp, a large proportion of its lighting power is lost, and tests which have been made, the Fig. 5.—Diagram showing Different Posi- tions of the Reversing Lever. standard being a sperm candle consuming 120 grains per hour, have given the follow- ing results : Davy, naked..... ae . = .398 covered...... 146 = 63 loss Stephenson, naked 306 ” covered : ‘ 131 64 loss Clanny, naked. 375 covered.... = 96 21 loss} Mueseler, naked a8. ” covered......-- = .385 = 4% gain The contradictory result obtained in the last case is explained by the more perfect venti- >- Fig. 6.—Path of Crank of Engine shown in Fig. 3. lation of the lamp considered, the flame, morever, not being cooled as in other lamps Safety lamps may remain in a stationary or slowly moving atmosphere of explosive for a considerable time without danger, the | latter increasing, however, with an increase of speed ; thus, a Davy lamp explodes when submitted to a speed of 6 feet per second ; Clanny, § feet ; Stephenson, 10 feet; Muese- ler, 15 to 20 feet, according to the dimensions of the outlet of chimney and the position of lamp.

Recent experiments of M. H. Pellat, com- municated to the French Academy of Sci- ences, tend to show that when two metal surfaces are brought very close together a slight change takes place in the properties of the surfaces. The change requires a few minutes for its completion, and gradually disappears again when the disturbing metal is withdrawn. The phenomenon is detected by measuring the differences of potential between the electric strata covering the sur- faces of the two metals in contact. The strongest effect of the kind is produced by lead and iren placed near another metal. Copper, gold and platinum give a distinct effect, but zinc does not appear to possess the |power. It would seein from these experi- ments as if metals gave off at common tem- | peravures a volatile substance which, when | deposited on the surface of objects, modifies | their chemical nature. This opinion of M. | Pellat appears to be supported by the smell of metals, a subject investigated by the late Professor Rankine, | | ALLOYS OF LEAD, COPPER AND ANTIMONY FOR SULPHURIC ACID CHAMBERS. There has been much conflicting testi- } mony as to the value of adding small quanti- | ties of copper or antimony to lead before rolling it into sheets destined for use in the construction of sulphuric acid chambers, and jit will therefore not be without interest to | give the results of experiments made by Mr. | John Glover, a well-known English manu- | facturer of sulphuric acid, and Mr. N. Cook- son. Mr. Glover had sheets rolled weighing 7 pounds per foot, and hung portions of them jin the first of a series of chambers 30 feet from the inlet and 1% feet from the top, | keeping them in these chambers, which were worked in the usual way, for a period of 110 |days. Unalloyed lead during that period lost 7% per cent.; lead, alloyed with the pro- | portions of copper and antimony given belew, | showed the following losses : ——Alloy of Copper.— —Alloy of Antimony.— f Loss Per cent. 0 Ss, Per eent, of Loss, Copper. per cent, Atimony, per cent, I 7.1 r > 2 i: 2 3 5 | 3 19.9 4 I } 4 11.6 15.9 It will b een from these results that such alloys are not to be recommended for the above-mentioned purpose Mr. Cookson took commercially pure lead and alloys of the same lead with o.1, 3, 0.5 and 1.0 om cent. of antimony, and heated them for dif- ferent periods in acids of different strengths, determining in each case the loss which the plates sustained aking the extremes of 4 hours’ boiling in strong acid, and 60 hours’ exposure to weak acid at about 120° F., the foll ng results were ¢ btained Bou & in L x . 8 cad to weak j rer Cent, Per cent, I ad 4.3 49 r cent. antimony 4 r cent. antimony : 8 °.38 per cent. antimony 8.26 o.1§ per cent. antimony » 9.00 18 Mr. Cookson stated as the result of his obser- vations that probably the physical condition eamanaen ane » —_— 3 ES RT 4.
