The construction of a center post panel from four pieces of stock of odd sizes shown in Fig. 5. Welding time on this type of panel construction is 5 min. The forming of the cowl on the Franklin bodies formerly presented many difficulties, due to the large amount of metal that must be formed and swaged over the front to form the front panel. This diffi- culty has been overcome by the welding process, as shown in Figs. 1, 2, and 3. Fig. 1 illustrates the cowl hammered to shape with very little metal formed over the front. The remainder of the front panel is made up by welding in small side sections or wings, as shown in Fig. 2. Fig. 3 shows the completed part, the front panel sections now con forming with the characteristic lines of the Frank- lin hood. The total length of this weld is approxi- mately 60 in. and the total welding time for both is sides is 7 min. A view of the Franklin roadster rear boot, welded into one solid piece, is given in Fig. 6. The min. The same class of work on a coupé rear boot requires a much shorter time, only 5 min., for welding. Welding of this character is carried out with the separate parts clamped on a frame, as shown in Fig. 7. Another operation which formerly presented difficulties in automobile body manufacture is the forming of door panels around the window frame openings. This. was formerly handled by slowly hammering the metal over the frame and carefully working in the corners, the process occupying a total time of over 24 and sometimes 3 hr. Even total time for these two welds is 7 4 Min ding from the Fig. 5—A Welded at A Doo!

A considerable loss of materia! was the result in a great many instances. This difficult is now overcome by using a small acetylene blow torch, which is similar in principle to the wel known Bunsen burner. The metal simultane- ously annealed and hammered by one man, as shown in Fig. 9. In this case the same cylinder of acety- lene that is ordinarily used with the oxy-acetylene outfit is now employed to furnish gas for the anneal- ing and hammering operation. The total time occu- pied by this newer method is 30 min., at a time cost of than one-fifth of what the old method of hammering cold formerly cost, and with practicall no loss. A striking example of the savings that ar being made in the laying out of patterns on alum num sheets is given in Fig. 8. The illustration 1s of a Sedan cowl, roughly shaped, with small pieces welded to the corners, a considerable saving in the size of the sheet necessary for this pattern. The total time consumed in welding the two corners A and B was 5 min.

In the majority of operations the f the sheets to be welded are turned at right to a height of from one-and-one-half to twice ckness of the metal.

Care should sed not to “trap” the flux in the weld, in ‘ 1916 THE IRON AGE 939 Fig ; Annealing Aluminum Window F: ! ()pe gz with Acetylene Blow Torch t - : me Without Cracking which case no amount of scrubbing would remove it. By “trapping in the weld” is meant the flowing together of the metal in the joint above and below the flux so that the flux cannot be entirely burned out. An advantage in using flux in a moist condition is that when applying the first coat with a piece of cloth both edges of the metal must be rubbed to a distance of about °4 in., which effectually removes any oxide from the surface of the metal and also destroys any greasy material that might form a film over the molten metal. After this is done a second coat should be applied sparingly with the stiff brush. No filling material is used in the welding opera- tion, except at such points as a defect may occur, either through the improper handling of the weld- ing flame or lack of a sufficient quantity of flux to allow the metal to flow together freely. In the lat ter case, usually a narrow strip cut from the same metal is used as a filler, and the operator re-fluxes the line of weld before starting to fill in the defect- ive spot. After welding, the line of weld is hammered flat under spring power hammers, similar to those used for flat hammer work in all sheet metal industries The Baby welding blowpipe used in this class of welding is a new product of the Presto-O-Lite Com- pany, Inc., Indianapolis, Ind. It is peculiarly adapted to sheet aluminum welding on account of its small size and its easy manipulation. With it a workman can weld thin sheets more rapidly than with the heavier type of blowpipe such as is com- monly used in large repair work. British Pig Iron Output in 1915 Great Britain’s pig-iron output in 1915, according to the data published by the Iron, Steel and Allied frades Federation Statistical Bureau, was 8,793,659 gross tons: 53,000 tons of this is estimated. The total was made up of 1,024,063 tons of forge, 1,573,575 tons of foundry, 2,272,684 tons of basic and 3,564,276 tons of hematite iron, 255,484 tons of spiegeleisen, ferro- manganese and ferrosilicon and 103,577 tons of direct castings. Out of a total of 489 furnaces, 291 were in blast.

Lewis, professor of physics and assistant professor of engineering at Swarthmore College respectively, at the spring meeting of the American Society of Mechanical Engineers held at New Orleans, La., April 11-14, a new form of viscosimeter is described. It operates in accord- ance with the principle that a solid body having a sur- face of revolution when suspended in a rotating liquid experiences a torque which is proportional to the vis- The Viscosity of an Oil is Here Measured by the Twist Given to a Body When Oil Chamber Is Revolved cosity of the liquid under test, such as a lubricating oil. The specimen S is contained within a cylindrical chamber that is rotated uniformly by a motor, M, through a worm drive, R, A cylinder, C, is suspended within the specimen by a thin steel wire, W, so that the axes of the rotating liquid and the cylinder coincide. A cap, V, shaped so that the excess liquid can overflow when the cap is seated and thus give constant condi- tions within the specimen chamber, is provided. The specimen chamber is surrounded by an oil jacket, J, in which a thermometer, 7, is suspended. The jacket oil may be brought to any desired temperature by a heat- ing coil. The cover of the jacket chamber D has a scale graduated in degrees or may be calibrated to read the viscosity in terms of a standard liquid directly through the deflection of the pointer P. The speci- men chamber and the suspended cylinder are both made of copper to insure a constant temperature throughout the specimen and the outside of the specimen chamber is provided with blades which keep the jacket oil thor- oughly mixed as the chamber revolves and thus ex- pose the latter to a uniform temperature. This, it is explained, is an important factor toward insuring con stant temperature throughout the specimen. Experimental work conducted with the machine has shown that the temperature of the specimen is uniform to within a small fraction of a degree and follows that of the jacket oil so closely that the temperature-vis- cosity curve can be taken while the temperature is slowly raised or lowered. This has proved to be a great saving of time and also saves labor, as it is not neces- sary for the operator to stand by the instrument con- tinually. The deflection of the pointer is at any instant a measure of the viscosity, so that all that is required is to take simultaneous readings of temperature and de- flection at intervals in the heating or cooling process. The Steiner Mfg. Company, gasoline engines, Plymouth, Wis., has been obliged to place an overtime working schedule in effect to enable it to fill orders. Further orders from the Pacific coast have made this necessary.

E. Gallon in the March issue of the Foundry Trade Journal (British). He considers that the height of the cupola stack affects coke consumption to an important degree. The distance from the tuyeres to the charging door is usually arbitrary, with published data based rather on what is accepted as fairly good practice than on any law. This particular factor is generally obscured by such variables as blast pressure and density of the charge. Mr. Gallon contends that the higher the stack, within practical limits, the greater the efficiency of the furnace. It is not known whether this is because of the longer contact of the hot gases with the iron, longer con- tact with the coke or by creating increased resistance to the travel of the gases. The amount of oxygen blown in is not affected by the height of the stack, and if that oxygen combines with carbon in the melting zone to form CO,, the only further change it can make is CO, + C= 2CO, resulting in waste of fuel without further heating. But if a proportion of the oxygen is already passing off as CO, because of imperfect com- bustion, no increase in height will alter the fact, though it would abstract a little more heat from those gases the same as with CO, or any other hot gas.

W. Akimoff of the Dynamic Balancing Ma- chine Company, Harrison Building, Philadelphia. He regards it as employing a new principle, and he Balancing Cage a Vibrations are Limited to a Vertical Movement and the Cage Below Is Adjusted to Neutralize Them presented a paper descriptive of it before the meet- ing last week in New Orleans of the American So- ciety of Mechanical Engineers. He differentiates between static balance and dynamic balance. In other words, he calls atten- tion to the fact that an unbalanced condition of a rotating body may be due either to lack of static balance or lack of dynamic balance. The static balance may be obtained by a static balancing ma- chine which involves the drilling of one hole or the adding of a weight to bring the center of the mass of the body somewhere on the axis of rotation. In a statically balanced body, however, there may be two masses on opposite sides of the shaft, located axially some distance from each other. Such masses, owing to the fact that there is static balance, must be in the same axial plane and the products of each mass and its respective distance from the axis of rotation must be equal. However, the two masses on rotation form a couple with the result that when high speed is developed the vibrations manifest themselves, as is noted in the defective commuta- tion in electrical machinery, with wear on bearings, or, in the case of grinding disks, defective products. The object of the Akimoff machine is to estab- lish another couple which shall still maintain the static balance, but also oppose the couple which gives unbalance at high rotative speed. The prin- ciple of the machine may be gained from the ac- companying drawings. A rigid horizontal beam, such as a lathe bed, is hinged at one end and supported by a spring at the other. The body to be tested, already in per- fect static balance, is rotatably supported on the beam. If dynamically unbalanced, the body will, when rotated, cause the beam to vibrate in a vertical plane, with a period of oscillation equal to the 942 THE IRON AGE April 20, )\1¢ period of rotation of the body. In other wor the speed of the unbalanced body is, say, 315 rm. the beam will vibrate at the rate of 315 com»tete oscillations per minute, quite regardless of the ¢ jar. acteristics of the spring (except possibly at the very beginning of motion). “Now imagine a second body,” says the author. “exactly similar in every respect to the first, als in perfect static balance but dynamically unbalanced to precisely the same extent as the first body, ten porarily associated with the same beam, say sus pended under it. If these two bodies are opposite located as to balance and run precisely at the same speed (synchronously), then the unbalancing or dis- turbing couples will cancel out, and the beam wil] have no tendency to vibrate, no matter how badly unbalanced, individually, are the two bodies. This is the fundamental principle of the machine—t determine unbalance by determining the unbalance necessary to neutralize its effect.” In the actual machine instead of the second bod) being an exact image of the original unbalanced body, it is a so-called squirrel cage, and this is rotated in unison with the article to be tested. The cage, as indicated, consists of two or more circular disks, carrying an even number of rods (usually six or eight) arranged slidably in the disks. The rods are accurately made and their common weight is known; therefore, any displacement of one of the rods with respect to the one exactly opposite will not affect the static balance, originally perfect, of the cage, but will introduce a certain centrifugal couple, according to the relative displacement or added distance. As an example of the use of the machine, the author considers the case of a ventilating fan, shown in one of the drawings. The unbalance may be due to two excess weights grossly exaggerated in the figure. This will result in a centrifugal couple, and to counteract it the cage will have to be put into a state of unbalance as shown by the relative displacement of the rods and as measured by the added distance. Thus the cage has means for indi- cating the exact amount of the unbalance which has been put into it in order to reproduce with the opposite sign the exact unbalance of the article being tested. For instance, the displacement or added distance of 15/16 in. may represent for a cer , congested ragions —_- oor oo sip oaine To seid »+ anise | ™ “ added distance The Scheme for Neutralizing and Measuring Unb Illustrated in Case of Fan Wheel tain speed a couple of 120 oz.-in.

An in- teresting feature is that the rods of the cage may be adjusted axially while the cage is in rotation. A set of tables is provided with the machine so that the operator can pick out the necessary direc- tions as how to remove a certain amount of metal from one of the cranks of the automobile engine, for example, and how to drill the flange in order to secure the balance. The author admits that one pair of rods would suffice if the relative position ' the reds could be altered through the transmis- n device, but for convenience three or four pairs rods are employed and even then it is sometimes essary to change the angular position of the 0 that the balancing can be done by one pair ‘ods and not two, as often happens at the be- r of the test. » Universal Horizontal Routing Machine : (he routing of the vent and powder grooves in » ‘he fuse rings of shells is the special field covered ichine that has been developed by the George Machine Company, Racine, Wis.

Thus the United States produces just about two tons of ore for every ton of pig iron, and we know that our ore runs about 50 per cent in iron; but this method fails when we apply it to countries that either import or export a large proportion of their output. Thus Belgium raises no ore, yet it makes more steel per capita than any other nation, while Spain and Sweden export large quantities of ore but produce comparatively little iron. The output of coal follows more closely the pro- duction of iron; and while there are exceptions we find that on the whole a nation which is a leading producer of steel mines a large quantity of coal. One or two countries have overcome natural disad- vantages. Thus Sweden has hardly any coal and must use charcoal, while Italy imports fuel for smelting iron. PIG IRON AND STEEL There is no necessary connection between the amount of pig iron and the tonnage of steel pro- duced. Thus Petrograd makes no pig iron, but imports it to make steel; on the other hand, Ala- bama made pig iron for many years but not a pound of steel. Moreover, there is a complication in steel statistics, for the figures usually given are the tons of ingots cast, while the scrap made in rolling will be put back into the melting furnaces and appear over and over again in the course of a year, and we know also that old material ulti- mately finds its way back to the steel works and appears again in the form of ingots. The United States and Germany and other na Per Capita Output CAMPBELL tions make just about a ton of steel for every top of pig iron; but Great Britain produces only three tons of steel for every four tons of pig iron, be. cause a great part of the iron smelted from the native ores of England is not well adapted for making steel, although it is excellent for foundry use. As a consequence, Great Britain exports large quantities of pig iron to Belgium, Germany, France, Russia and other countries. Conditions in Italy are just the opposite, for almost all the pig iron is melted in open-hearth furnaces with an equal amount of scrap, so that the tonnage of steel js twice that of pig iron. POUNDS OF STEEL PER CAPITA The amount of pig iron made or used per capita is often taken as a yardstick by which to measure the civilization of a nation; but it seems better to take the steel production. While on the one hand the tonnage of pig iron is a measure of real pro ductive power, since practically every pound of pig iron is a new creation from crude ore, yet on the other hand the manufacture of steel shows a higher development of metallurgical science. We must also distinguish between production and consumption; but to find the amount consumed would require a long analysis of tables of imports and exports, an inquiry a little outside of our field, so that Table A shows the amount produced. Belgium and the United States come first in the amount of steel made per capita, with Germany and Great Britain following. As just remarked, we should subtract something from the record of the leading producers to balance their exports, and we should add something to countries like Spain and Italy to make up for their imports; while, of course, the figures mean nothing if applied to a countr) like Holland, which makes no steel at all. NON-PRODUCERS OF STEEL Before taking up the leading iron-producing na tions it may be well to say a word about those that do not loom large in the statistical tables. Nor- way, Denmark, Holland, Switzerland and Portugal! produce practically no iron and mine hardly an) ore or coal, so that they may be dismissed from consideration; but the Balkan states may not ° disposed of so summarily, for travelers have told us of mineral deposits in those countries, albe!t these stories have little weight with metallurgists There may be coal there that will serve very Wwe! in a cook stove or a blacksmith’s forge, but be use less for smelting pig iron; while an ore bed, whit! a newspaper correspondent would describe as inexhaustible supply,” might last a modern Dias furnace about a week. The last edition of the Encyclopedia Britannic says that “Bosnia is rich in iron and coal,” but ™ the Austrian official report we find that although Bosnia has been producing iron since 1881, ™* output in 1912 was only 145 tons per day, whit? could be made in one furnace of moderate size. TH output of ore was 435 tons per day, and if this was all used to make the pig iron, it only contained 32 per cent of iron. These facts will indicate ho¥ Je 944 ance can be placed on general statements y natural resources. SPAIN ed as a producer of iron, Spain occupies a all place in the world, but there are only tions that produce more iron ore. From times the iron made in the northern prov- as been renowned for its quality; and as coal near by, we have the essentials for a hing steel industry. Spain is, however, a ard country and the market for miscellaneous ts is limited; as a consequence Spain has elling her birthright for a mess of pottage English iron masters years ago bought for a the mines around Bilbao and for half a cen- tury have been carrying the ore away. Some has been and is still being shipped to Germany, France, Relvium and the United States, but the greater goes to Great Britain. For long years the average content of iron in the ore that is shipped has shown a steady decrease, mineral being mined to-day which would have been rejected a few years ago, and from time to time predictions have been made of the exhaustion of the deposits; but somehow these dire prophecies never have come true. It is certain that all the mines will not give out simultaneously and that the end will be long postponed by mining inferior ores, while it is quite possible that new deposits will be found. Nevertheless it seems more than probable that before many years the end must come to the huge exports of ore that have played so important a part in the international iron trade for fifty years. SWEDEN Sweden is known to every one as the producer of the best grade of wrought iron and steel, al- though she is cheated out of some of her just due because men will speak of Norway iron, just because it came from a Norwegian seaport. This superior quality is partly due to the purity of some of the Swedish ore and partly to the use of charcoal as uel. There is no good coal in Sweden and so her ron masters have made a virtue of necessity and e devoted themselves exclusively to making pure ron and steel for special purposes. Sweden is not of the first rank, if we merely of the tonnage of iron and steel produced, important as an exporter of iron ore and enters our problem, particularly with regard England. There are large deposits north of the Circle, but the mineral is scattered irregu- n hard rock and much of it must be ground i magnetically concentrated. It is sent across : Men get to an ice-free port and shipped to “ngiand, Germany and the United States. geographical point of view this ore ll go to England, and in a certain measure say that it would make up the shortage hound to come when the mines of Spain But this Swedish ore costs more than the at has been drawn from English-owned nines; it is more difficult to smelt and a portion of the output contains too much to be suitable for the making of acid ese facts have an important bearing on ¢ the steel industry of Great Britain. ITALY “ration ago Italy exported ore from the Elba, where mines were worked more years ago; but the government has now ; commandeered what is left and reserved onsumption. As the reserve is small 1916 THE IRON AGE © and as fuel must be imported from England, in the absence of any coking coal at home, it does not seem likely that Italy will develop into a formidable competitor for the iron trade of the world AUSTRIA-HUNGARY Austria-Hungary raises a little more ore than is needed at home and sends the surplus to German Poland, but there is only one large deposit of fairly good ore in the dual empire, and this is in Styria in the south, as far as it could get from the best coal in the country. Since even this coal in the north gives a poor coke, the works in the south bring coke all the way from western Germany, this long rail- road haul of blast furnace fuel being matched no- where else in the world except in the trip from Connellsville to Chicago. From these facts it would seem that Austria will not be a big factor in the steel trade of the world in the near future RUSSIA There are several old-established iron districts in Russia, but all save one can be eliminated at once from this review. The Moscow and Ural dis- tricts depend on charcoal for fuel; Petrograd uses imported coal and iron, while Poland has almost no ore and very poor coal, and is only kept alive by coke brought from Austria and by government help in the form of low freight rates on ore from south- ern Russia. We have a different state of things in the south, near the Black Sea. Here there are extensive de- posits of coal which are far from being of the best quality, but yield a coke suitable for blast furnaces. We also find here a bed of iron ore known as the Krivoi Rog. This ore is rich in iron and low in phosphorus, and if there were an unlimited amount of the mineral it might form the basis ef a world- wide trade; but the end of the supply can be fore- seen, and it is probable that about all the output of this region will be needed in Russia. There are other beds of iron-bearing mineral in the Crimea, but it is difficult to get accurate infor- mation about them, for the ore occurs between strata of worthless earth and reliable observers have varied widely in their estimates of the quan- tity and quality of the reserve. The output of South Russia is constantly increasing, but there is no sign to-day that its plants can compete in price with the outside world. GREAT BRITAIN, GERMANY, FRANCE AND BELGIUM We have now considered all the nations of Eu- rope except Great Britain, Germany, France and Belgium. These are the countries which have been in the past, and will be in the future, the most active competitors of the United States. They will be most affected by this war and we are more inter- ested in their history and their future than in the story of other countries. We will therefore take up these nations more in detail in future articles The production of anthracite in 1915, as shown by the final figures compiled by C. E. Lesher of the United States Geological Survey, from returns made by the operators, was 79,459,876 gross tons, differing from the estimate of 79,100,000 tons published last January by less than one-half of 1 per cent. Compared with the figures for 1914, those for 1915 show a decrease of 2 per cent in quantity and 1.9 per cent in value. There were 148 machines used in underground mining of anthracite in 1915, and 57 steam shovels were used on the surface. The steam shovels are nearly all used in the Schuylkill and Lehigh regions, and the mining ma- chines in the Wyoming region.
