The Iron Age A Review of the Hardware, Iron and Metal Trades. Published every Thursday Morning by Davim Wrixiams, No. 83 Reade Street, New York. Entered at the Post Office, New York, as Second-Class Matter. Vol. XXX: No &. New York, Large Drawing and Stamping Press. Mr. E. W. Bliss, of Brooklyn, N. Y., has just completed a new stamping and drawing press which, in design, size and style of work to be done, is unique. It is built on a plan rarely seen at the present day in large presses, the driving shaft being at the bottom and the work above, with all the strains taken di- rectly upon connecting-rods at the sides. The ress is an original design made for the En- ameled Metal Stamping Company, of Zug, Gwitzerland, a town not far from Zurich. The press itself weighs 65,000 pounds and stands 18 feet high. The largest work it is intended to make is a dish or pail 26 inches in diameter and 16 inches deep, from a disk or blank no less then 49 inches in diameter. This, we believe, is the largest piece of sheet metal stamping that has ever been attempted either in this or any other country. The en- graving gives a very good idea of the gen- eral appearance of the press and its con- nections. In its working parts it consists essentially of a main shaft carried in brack- ets, supporting a bed-plate on which are two standards carrying the guides for the punches, and between which blank holders, &e., are placed. A pair of connecting-rods en each side, coupled to cranks below and to a cross-head above, transfer the motion of the cranks to the dies. The size of the press is so great that the weight of the parts alone is sufficient to do some of the work usually performed by separate cams. For example, the blank holders fall by gravity, and, after seating, are held in place by stops, shown in the figure like bent levers, pivoted on each side of the main cross-head. These are actu- ated by two short slotted arms shown stand- ing at an angle in front of the cross-head. Through the center of these the blank holder, die holder or plunger works, being forced down by the connecting rods after the blank holders have reached their proper place. These holders are so heavy that al- though cored out to some extent, they are counterbalanced by a cast-iron box weighing some 3000 pounds, This box is sustained on the ends of two beams at the top ot the machine, which are connected at their front ends with a set of equalizing bars. The blank holders are lifted by wrought-iron cross-heads which, in the up stroke, rest upon the top of the main cross-head. The amount of power re quired and the strains which the press must withstand in doing this work, can best be guessed from the fact that there are two 62 inch fly-wheels on the shaft, each weighing 1900 pounds. The driving pulley is 36 inches in diameter and 12-inch face, and the press is geared 60 to 1. The shafts, which have three bearings each, are respectively 4, 5, 6 and 7 inches in diameter. They are parallel pieces of steel without shoulders or collars, and have bronze boxes. The main shaft, which is 7 inches in diameter, is relieved from all torsional strains by double gear wheels upon each end, the crank-pins being in the gear wheels. These pins are 5% inches in diameter by 6 inches long, and like the shafts, are parallel pieces of steel. ‘lhey are the same size in the crank-eyes as in the journals, and are forced in by hydraulic pressure. The hubs of the wheels form the collars and hold the shafts in place. To do this the gear wheels, especially the larger ones, are put on in a peculiar manner. Two feathers, 1% inches square, are let into the shaft, over which the wheels are slipped and held fast by two keys driven on the top of these feathers. These keys are only 114 by 7%, with a draft of about 1-16th inch in 10 inches, The distance between the uprights on the working table is 50 inches, which is practically the largest diameter of blank. The die opening in the blank holder ring is 39 inches, which is the largest punch that can be used. The stroke of the top die is 36 inches and of the blank holder 16%. The friction-clutch used for this press is actuated by a wedge, but the wedge is adjustable in such a way that only a given and fixed amount of pressure can be obtained from it. When more is wanted an adjusting screw and gib can be used to obtain it. The con- necting-rods are of a type which deserve to be better known, consisting of two rods with shoulders at suitable distances apart, upon which the boxes are held by nuts. The shoulders insure the parts going together at the proper length, while the division of the rods into two parts makes the quality of the metal much more certain, and enables a lighter rod to be made than would be possible with a single forging. This press is intended to make a variety of goods from black iron which are afterward enameled, and it shows the growing tendency to abandon piecework 1ud make more and more of our heavy sheet metal ware in pieces. The great hight of the press makes it necessary to place it upon two floors, the workmen being elevated nearly © feet above the foundation level. Although Mr. Bliss has built some very massive presses, ‘ud some of which, at the time they were de- ‘igned, were the largest ever constructed, *teven the heaviest of these seems to be ‘warfed when placed alongside of this one. - a ~ : According to the Moniteur des Interets Ma- ‘rtels, the Sarre coal district is already be- ‘thing to profit by the opening of the St. ‘Othard Tunnel. Up to the present time consignments consisted chiefly of trial ‘ders, and several months will probably “apse before it will be possible to judge the ‘obable importance of the Italian market ‘0 the future. During the month of June Pagut 4009 tons of coal passed through the “one ‘ Water-Tight Bulkheads., One of the daily papers recently had the fol- lowing article in regard to water-tight bulk- heads in steamers : The safety inherent in the water-tight bulk- head system, as such is now practiced in the building of seagoing steam vessels, has been lately a fruitful theme of discussion in Eng- land. The safety afforded has been attacked by the lay press vigorously indeed, while the journals devoted to engineering, shipbuild- ing and other kindred mechanical subjects, have rallied to the support of the present system of surveying, inspection and classifi- cation, claiming that as now practiced it is the best that can be had under the pres- ent conditions of knowledge in such matters. A correspondent of Engineering, London, however, strikes a severe blow at the pres- ent practice when he writes in the issue of July 7, from Rangoon, as follows : ‘‘ Imadea point of observing these water-tight doors in shaft tunnels of screw steamers. I find that 8 per cent. might be shut in less than 10 min- | | Oe y Be a mn dia ela » ory STN Se LLL rT Wis 1e | cu lil | i 4H4)1!)t} iNT WN a i ah fi | — | ed —— — -_ ee LARGE DRAWING utes ; 22 per cent. in about 25 minutes, and not less than 20 minutes ; while the remain- der would take from half an hour to three- quarters of an hour to shut them, and in a few cases hours would be nearer the time. Of those observed, not 5 per cent. appeared to have been moved since the ship was built, being jammed with rust and paint, while those fitted with screws were in a hopeless state.” The foregoing was written by a practical man, whose range of inspection covered some 27 steam vessels actively employed in the East India waters and sailing under the British flag. In order to ascertain how far such severe criticism might apply to the steam fleet sailing from this port, several persons supposed to have a thorough acquaintance with the various intricate naval matters hav- ing a practical bearing on the question of the comparative safety of the present water- tight bulkhead system have been visited. | Mr, Thomas Congdon, principal surveyor in the United States for Lloyd’s Register of British and Foreign Shipping, said: ‘‘I am certain that no such state of things as has besn reported in Engineering could exist in vessels surveyed and registered by us. When making our annual survey particular attention is paid to the working of | the doors in the bulkheads ; for, as you can | see, in our regulations great stress is laid | upon the point of examining the water-tight | bulkheads in all their details. We not only | examine the officers and engineers about the | efficiency of the doors, sluices, &c., but we Thursday, August 24, 1882, nel door,’ or the opening from the engine room to the shaft tunnel, is an opening of vital importance, and yet, strange to say, in some cases it is neglected shamefully by care- less or incompetent engineers. ‘‘The passage is used a great deal, and, you know, ‘ familiarity breeds contempt.’ Too much care, however, cannot be paid to these doors, which, in case of accident, must be closed instantaneously from the deck above, and it is possible, also, that, though found efficient in its working to-day, a door might fail to close tightly to-morrow. Many prac- tical reasons can be given for this. The after hold is very large in the modern steam ship, and so is the engine and boiler space, and if, by reason of the bulkhead between them not being water-tight, both are flooded, destruction is certain. This is one reason why ruptures of the after portion of the ship always prove so fatal in collisions at sea. The greater number of collisions which occur in ocean navigation fortunately happen when the vessels are ‘end on’ or nearly so, and ruptures of the forward compartments are AND STAMPING PRESS, BUILT BY E. W. BLISS, not so dangerous to the safety of the ship as those abaft of midships. Thepresent system is as near perfection as the ingenuity of man can devise, but, of course, there are many fortuitous, perilous conditions which attend navigation against which no human skill can provide. Many of the Atlantic steamers are not registered with us, but, I fancy, they are with some other company, and I feel war- ranted in saying that no such shameful state of affairs as is stated in the foregoing can be found aboard of any of our first-class Atlan tic passenger steamers. Bulkheads and doors, | with all theiraccompanying machinery, may be constructed in the highest degree of perfec tion, and yet, by neglect and stupidity, be come worthless, and again, they may be perfect to all appearances, yet fail when needed. No skill can discount the action of the force of concussion when two vessels col- lide.” Mr. Samuel Holmes, iron shipbuilder and ‘surveyor, said; ‘‘The steam vessels plying in the East India waters come home only once in 6 years to have new boilers, &c., and the officers, engineers and crews get care less, no doubt; the hot weather, too, makes them neglectful, and collision risks are rot so great in that part of the world as about here or in European waters, In every well regulated steamer the doors should be worked every day, and the attending machin- ery well oiled. As much difference exists among steamships in this important respect as can be found among men generally. En- gineers are no exception to the general rule, ing is too often the case, and, in my opinion, | criminal to the last degree.” In the office of the United States Inspector of Steam Vessels, no one seemed to know of | any such rule, nor was any one impressed with its importance. In fact, they seemed to know very little about water-tight bulk heads and their doors, or anything else con- nected with the matter, Founding in Bavaria. [ron —epelll The Jronmonger correspondent at Nurem- berg, Germany, in a recent note on the ex- hibition at that place, gives the following of ficial statistics concerning mining and iron founding in Bavaria: The earliest records mention that iron ovens were cast in Alsace in 1490. Cast-iron cannon were manufactured in Prussia in | 1667. The first iron bridge was erected in | England in 1773, in Germany in 1794. Stat- | ue-casting in iron was first practiced abvut | the year 1780, at the Lentihentense Iron | BROOKLYN, N. Y. works. Fine castings for artistic and orna- mental purposes were first attempted at the beginning of the present century, at the Royal Berlin Foundry. Loam was formerly the only material used for molds, being em- ployed at the Harz ironworks as late as 1766, while in France sand rapidly gained favor for this purpose at about the same time. The tempering of cast iron, or the production of malleable cast iron, was accomplished some 80 years ago, a patent having been secured in 1804 by Lucas in England for the process, In Germany the method has been practiced since 1829. The iron foundry and enamel ing works of Bavaria in 1875 numbered 49, employing 2145 hands, The country is very rich in iron ores, various qualities of which are found under the usual geological condi- tions. The total ore produced by the 26 mines in 1880, was 73,560 tons. The most noteworthy and important is the ‘‘ Erzzug,” the principal point in this stratum being near Amberg, the mineral wealth of which place has contributed largely to the success of the ironworking in the Oberpfalz, Commencing at Altenricht and Haidweiher, the beds of ore stretch over Krumbach and Amberg, and in a northwesterly direction over Sieben eichen, Lobenhof, Annaberg, near Sulzbach. to Etsmannsberg, Langenbruck, Auerbach to Sassenreuth, near Pegnitz, and extend in numerous directions over the Frankenjura. These ores are now worked at the royal mine on the Erzberg, near Amberg; the St. George’s mine on the Lobenhof, near Rosen- berg ; and the Etsmansberg, near Sulzbach —. + $1.50 a Year, Including Postage. Single Cavies, Ten Centds. bach, and the Sassenreuther mine, which however are worked only at intervals: The principal ore of Amberg is brown ironstone, containing about 55.5 per cent. of metal- lic iron, 3 per cent of manganese, .8 phos- phorus, 10.3 water, and 14.4 per cent. of clay and quartz. Spathose ironstone of in- ferior quality is found at greater depths, es- pecially near Auerbach, analyses having given the following results ; Per cent. Metallic Iron.........0 Bases rceveved .. 38.54 Protoxide of Manganese....... 2.42 Phosphorus........... siebivis . 2.09 Carbonic Acid.... ...... . 30 80 The remainder consists of lime, dolomite, clay, quartz and water, 17 he ore beds, which are from about 260 to 2g0 feet wide, are at present worked at a depth of 115 feet below the deepest adit level. At the private mines }on the Lobenhof, the northern extension of the Amberg vein, which at that point is about 140 feet wide, 15,000 tons of ore are raised by 30 men, while still further north the private Etmannsberg mine employs 76 men and yields 33,000 tons. The once flour ishing iron industry of Bavaria, especially in the Oberpfalz, in the Pfalz, and in certain parts of Lower Franconia, has cisappeared in consequence of the high price of charcoal, the difficulty of obtaining coke, and the severe competition of ironworks in other districts. The following figures, showing the blast furnaces at work 20 years ago and now, speak for themselves : 1858 1868 1878 1880 Charcoal blast furnaces...... 77 20 5 5 Coke furnaceS.......+.. see ee 2 r 2 Even these few furnaces are not constantly employed, so that the total production of pig is small. The following figures are for 1880 : In Oberbayern (Higher Bavaria), total pro- duction of pig iron, 1572 tons ; in the Oberp- falz, 24.594; in the Pfalz, 3126. Of iron castings 60 works turned out 27,770 tons ; of rod and bar iron 26 works ees 66,787 tons; of black sheets five establishments made 2270 tons ; one iron wire works produced 2637 tons ; and one concern employed on steel wire turned out 760 tons, The number of men employed at all the ironworks amounts to 4780, and the output is valued at 18,908,147 marks, or about $4,440,000, Speaking of the exhibition, the corres- pondent states that of the different speci mens of iron ores shown, those from the Leonie mines are made up as follows: 74.160 Oxide of iron 1.912 metallic iron. .262 Oxide of manganese 1382 Manganese, 4 Sal Phosphoric acid 1.985 phosphorus, 1.699 ..Lime, oO.47% Mapnesia, 5.543 Silicie acid, 0 253 Sulphuric acid. it, S€ .Lost in working. Another sample shows 74.21 of oxide of iron, equal to 51.95 metallic iron ; 2.10 of ox ide of manganese, equal to 1.46 of manganese and 0.58 of phosphoric acid. Yet another of Etzmannsberg ore as 75.26 of oxide of iron, | yielding 52.68 of metallic iron. The various | specimens of rolled iron are all of excellent quality and reflect credit upon the respective works at which they have been produce d, cc ~- Coal Beds on Puget Soand,—A writer in Olympia, Washington Territory, says: fhe second great source of wealth of the Puget Sound region is the coal field lving back of its eastern shores up against the base of the Cascade Mountains. Its width is from 10 to 20 miles, and its length, when fully explored, will probably be found to be as great as that of the Sound itself, reaching from Carbonado northward to and beyond the British line, a distance of over 100 miles. At two points upon this field mining opera tions are carried on successfully by the aid of railroads to tide-water. The Central Pacific Railroad Company purchased re cently, for $500,000, the mines at Carbcn ado, about 20 miles east of Tacoma, and are shipping coal to San Francisco for the use of its locomotives. This coal is a true bitumi nous—hard, solid, black and clean, not equal in heat-producing capacity to the best Pitts- burgh coal, but a good fuel for railroad and steamship purposes. It is transported to Tacoma over a branch line of the Northern Pacific, and thence forwarded by sailing vessels, A number of steam colliers will soon be put in this trade by the Central Company, and extensive coal docks are now being built at Tacoma. Several new com- panies are preparing to open mines in the Carbonado district. This industry, now in its infancy, seems capable of indefinite ex pansion to meet the demands of the coast cities and of the agricultural regions of the interior, whicn are destitute of good fuel Back of Seattle, and reached by a narrow- gauge railroad, lies the Newcastle lignite field. The coal is of a younger formation, geologically speaking, than that of the Car- bonado district. It comes out in fine, clean, solid blocks, dces not slack easily, like the brown coals of Dakota, and has about two- thirds the heat-producing quality of bitu- minous coal. It is used by steamships, and finds a ready market for domestic consump- tion. Mines and railroad are owned by the Oregon Improvement Company, which has also a large shipping dock at Seattle and runs a line of steam colliers to San Fran- cisco, —— The total output of the German collieries for the second quarter of the year was 1,271,- 204 tons, against 1,179,171 tons in the corre- sponding period of 1881, During the first three months of 1882, 2,590,306 tons were raised, showing an increase of 6 per cent. on the total of the preceding year during the have them tested in our presence, The ‘ tun- | but neglect like that reported in the forego-| There are also the Leoni mine near Auer- | ame period, ~~ : oo eS De te ee = a THE IRON AGE.

The Levett-Miiller Electric Light Company, 540, 546 West Sixteenth street, New York City, are manufacturing a dynamo machine j which, in many respects, is worthy of | most careful attention, and is certainly capa- ! armatures and cores overlap the field mag- nets in such a way that they are not released from the influence of one before passing un der the following one, The magnets present alternate poles to the armatures, and there is no opportunity of reversing the current, the secondary current in one case passing through the coils in the same direction as the Fig. 1.—The Levett -Miille ble of producing some very desirable results. | Some of the claims made by the company for | their machines are so surprising that, at first | sight, it seems impossible to obtain such re- sults. Perhaps one of the leading claims will give a clear idea of the character of the whole of them. The inventor, Mr. Hans J. Miller, claims to make a machine in which the current is not only divided, as if it came from several independent machines, but it is ' r Continuous Arc Lamp, current produced by the following magnet, In other words, what would be the secondary current is in the same direction as that induced by the following magnet. This inclination of the armature cores is the sub- ject of a very important patent which was re cently granted to Mr. Miiller in an interfer- ence case with the United States Electric Light Company. By the use of this arrange- ment it is claimed that a very considerable Fig. 2.—The Levett-Miiller Incandescent Lamp, divided to produce quantity or to produce in- | tensity, as the case may be. In a machine | which we saw at work recently, there are | 12 field magnets disposed in six pairs. There are 24 armatures connected with four commu- | tators, so divided as to give six to each. | When this machine is arranged for intensity | the current passes through all in succession, but when it is necessary to obtain quantity | only, each one goes directly tothe commutator. In other words, the machine is divided into | saving in power is effected in producing a given amount of current. In one of these machines, for plating purposes, no small amount of advantage is to be gained on ac- count of the possibility of varying the inten- sity and quantity without the necessity for the introduction of resistance coils. The ma- chine, it is said, solves in avery convenient way the question of subdividing the electric current in an economical manner, Among one of the advantages for lighting which the Fig. 3.—Transverse Section of the Levett-Miiller Dynamo, four or more different and separate machines, | company claims is that arc lights of from 200 so far as the connections are concerned. The | current then can be sent in succession through each one of the sections or taken di- rectly from each. The machine, therefore, | resembles, in some respects, an ordinary | battery, which may be connected either | for intensity or for quantity, as may be de- | sired, It is even possible to connect a por- to 100,000 candle-power can be produced at the same time that incandescent lights of from 10 to 16 candle-power are being sup- plied from the same machine, either on the same circuit or separate currents. For steamers and railway trains, where enormous head-lights are needed and comparatively small lights for other purposes, they of course tion of the machine for quantity and another | would be a very great convenience. portion for intensity, and thus from the same machine to obtain a current capable of plat- ing, another suitable for incandescent light, and « third current for supplying arc lights. The armatures are oblong in section and are arranged so as to be placed at an angle In some experiments which we recently witnessed in connection with this machine we saw what struck us as rather a remarka- ble combination. It was a large are light in the same circuit as a dozen or more Edison incandescent lights. Both seemed to work to their line of motion. That is, they cut in a most perfect manner, and the lights were exceedingly satisfactory, By means of “ me a ~ SS 2 ee —- = 7> — :3 4. THE 1LRON AGE. August 24, 1882 OGDEN & WALLACE,|A. B.

JUSTICE COX, JR. & CO., incandescent, may be shut off or turned on ing on the ratchet wheel and its shaft raises the lower carbon holder. Since the positive carbon is consumed twice as rapidly as the negative carbon, the wheel which is moved by it must naturally have twice the diamete: of the wheel which moves the negative ca bons, As long as there are any carbons in the first lamp the current passes into the posi- tive carbon-holder, the positive and negative carbons, the helix, the joint piece of the armature, and from there to the generator, During this time the armature at the side of the helix is attracted by the pole-piece at the lower end of the helix. As soon as the first set of carbons is consumed to such an extent as to interrupt the circuit, the side armature is released from the pole-piece and is pressed against a contact slip which sends the cur- rent through the second set of carbons. As soon as the second set of carbons is con sumed the armature of that lamp is released in the same way, sending the current to the third set, and so on. By this ingenious arrangement a battery of lamps may be kept in operation for a considerable period. Two sectional views of Mr. Miiller’s incan- descent lamp are given in Fig. 2, the in- ventor having secured the following im- portant results: The carbon filament may be replaced without breaking or rendering useless any part of the lamp, and the en- trance of air through the joints between the plug and the conductors, passing through it to the carbon filament, may be entirely avoided. The glass globe is furnished with a strong neck, fitting very tightly on a bev eled glass plug, which is secured air-tight by means of packing material in a hollow base, D, adapted to be screwed on or otherwise attached to a bracket or chandelier arm The plug and neck of the globe are ground together so as to make an air-tight joint. The packing above me entioned is introduced as shown in the engraving, and two carbon conductors pass through longitudinal open ings in the plug, projecting at the top and bottom, and held in place by a suitable cement. The apertures through which the conductors pass are provided with copper rings, projecting slightly from the ends of the plug. The projecting ends of the car bons will be strengthened in this way and prevented from being broken off. The upper ends of the carbons are pro vided with slots, into which the ends of a carbon filament are passed and secured by means of a peculiar cement. A glass seal tube projects from the bottom of the plug through the base of the lamp, in which it i secured air-tight by means of cement. The end of this tube extends through the plug instantaneously, and the same current that 230 S. Third St., Philadelphia, Pa, ae OLD RAILS, SCRAP, &o. without difficulty.
