e ir INDEX TO READING MATTER, PAGE 3). XXXII: The Magnetophone. ] al tain experiments of Bell and ~— : the radiophone suggested to Prof. H. : ‘arhart, of Evanstown, IL, ‘ interrupting, or at least periodically modi- ‘ing, the lines of force proceeding from the -‘of a magnet by means of a disk of t iron, perforated with a series of equi- it holes, and rotated so that the holes d pass directly in front of the magnetic For the purpose of verifying his hy- is, he had constructed a disk of sheet pierced with two circles of \-inch es concentric with the disk, the number ‘holes in the two circles being 32 and 64 wtively. On one side of the disk was 1 a horse-shoe magnet with its poles very near the rows of holes; on the other | jde were arranged two corresponding in- | ion bobbins. The circuit was completed ugh a telephone and either bobbin at | easure. Upon rotating the disk rapidly, | a cle ‘ar, musical sound was produced in the | elephone, the pitch rising with the rapidity frotation. Moreover, the bobbin opposite | . circle of 64 holes gave the octave above | 1c other, and each gave a note of the same tch as was produced by blowing a stream of air aco the corresponding holes. Non-magnetic metallic disks produced sim- ur musical notes by the periodic modifica- tion of the magnetic field by means of the jistortion or bending of the lines of force. The solid parts of the conducting aisk deflect e lines of force in the direction of the rota- tion, but upon the passage of a hole they fall ack toward their normal position. A peri- dic movement of the lines of force will therefore take place when the disk rotates. Disks of zine and copper produced a clear, nusical sound, somewhat less intense than that given by iron under the same condi- tions. Any discontinuity in the rotating isk recurring periodically will produce cor- responding induction currents in the bobbins. \-shaped notches round the circum- ence of the disk are quite as efficient as he holes in effecting the requisite modification fthe magnetic field. Moreover, it is not neces- iy that the holes extend entirely through ie disk. Two disks of zinc, of the same di- neter and thickness, were placed together n the same rotating spindle, one pierced with a circle of holes, and the other not. The mbination proved as efficient in producing » sound as the single perforated disk. A sheet of tinfoil, with a circle of small holes, | is pasted on the continuous zinc disk. The -forations, extending only the thicknes. | { the tinfoil into the compound disk, con- | ituted a sufficient discontinuity to produce | : clear, though somewhat faint, musical | und. About the same re.ult was given by | i disk consisting of the same sheet of t.nfoil usted on cardboard. Any periodic varia- n from uniformity in the disk appears to | roduce corresponding variations in the ignetic field when the disk is rotated. Since the pitch of the note obtained de- ends only on the number of holes passing | pole of the magnet in a second, it is easy ‘onstruct a piece of apparatus to illus- rate musical intervals, A cylinder of gal- nized iron, with four rows of holes in the itio of 4, 5, 6, 8, was mounted on a whirl- g table, and provided with two U-magnets ind two electro-magnets for induction. The itter were placed inside the cylinder, and e former outside. By means of four keys, one of the bobbins, or all of them, can put in circuit with the telephone. By de- essing the keys, the four notes of the com- n, or major, chord are brought out with eat distioctness and clearness. In fact, intensity of the sounds obtained by the snetophone is something so great as to be nful to the ear when the telephone is held ely against it. — I —— Styrian Tool Steel.—In making this | the ore is smelted in the usual manner | run into cakes instead of pigs, that form gthe most suitable for subsequent treat- it. The cake, or pig iron, is then broken pieces of a suitable size and held by » tongs in the fire of the retinery forge, e it is brought down to a shapeless lump » well of the forge.

The lump is then cut into s and drawn into rough bars under tilt mers.

Published every ee — by Davip Wi.uiams, No. 83 Reade Street, New York. Entered Emery Scales and Testing Machines. There are few of our readers, who are not familiar remarkable work performed by the Watertown testing machine. That after recording hundreds of thousands of pounds it will show the strain which breaks a horse-hair, or, when testing to hundreds of thousands of pounds, read toa fraction of its load as small as that of an analytical balance, are facts which have caused the greatest wonderment and curiosity in regard to the re- markable mechanism by which these results have been accom- plished. It is evident to those who are familiar with the ap- paratus and the way it has been developed that a revolution in machinery for weighing is at o™ and, in fact, few professional men generally in the with the Fig. back-lash or the wear of pivots or knife edges. The importance of this we can the better understand when we refer tothe work of some of the best analytical balances of the country.

Zen Cents. On cne edges crushed and worn into rounded forms, but the fulcrum distances are by this means changed, and consequently the accuracy of the scale is lost. The fine scales for weighing silk are intended to take 1 pound, and are sen- Sitive to xq, part of the load—that is, with 1 pound in the pan—and they will indic ate I grain. Disbelieving the manufacturer's es ment that 5 pounds would ruin this scale, friend of ours bought one, and after testing it well within its capacity attempted to weigh 5 | pounds wihit. After this weight had been | | put on he found that although the scale still moved with a single grain, \ et it would not weigh a pound twice alike to within a grain. In other words, the overloading had not only destroyed its sensitiveness, but had ruined it for accuracy by changing the fulcrum dis tance. In contrast with this we take the scale beam of the testing machine at the Water town Arsenal, which was used before the machine was finished as an ordinary beam scale by the prolongation of its weight beam. When rigged asa balance, 100 pounds was put in the pan and weighed seven times, and the greatest difference between the maxi- mum and minimum weights obtained was one part in 1,750,000. A 200-pound standard was afterward weighed nine times in suc- cession. Here the greatest difference be- tween the maximum and minimum weizhings re- | Was one part in 2,350,000. The sensitiveness of the scale when thus used with the 200 pound load, stated according to the ordinary method, was equivaJent to the scale turning with y_ 505 goo part of its load. In other words, a scale beam with its fulerum capable said | of sustaining without injury a load of 4000 if | pounds has been made more sensitive than finest analytical balances yet made in this or any other country. Indeed, the same beam, if we understand Mr. Emery’s state ment correctly, might be used for analytical work with a far greater perfection than is at- tainable with the ordinary balances inside of their range of accuracy. To understand how such accuracy is possi- ble, we must first get an idea of the nature of the fulcrums used and the levers employed in Mr. Emery’s scales, gauges and dynamo- meters. The second step will be the means used for transmitting enormous loaas on heavy scales or the strains of large testing machines to the weighing apparatus. Lastly will follow a description of the methods of balancing the beams and reading the loads. Figs. 1, 7 and 8 illustrate the arrangement of these fulcrums and levers as applied to a pressure gauge or weighing dynamometer. fhey consist of thin, flat pieces of steel of suitable widths and lengths, forced into grooves or held between columns. In Fig. I, a, d, 6, ec represent these ftulcrums made of flat pieces of steel, and e and f show similar fulerums where two flat strips of steel take the place of a wide one. ‘The method vf connection and the variations of the bearing are shown in Figs. 7 and 8, which are enlarged details of certain parts of spec al scales or gauges. In the case of the gauge or weighing dynamometer, A (Fig. 1) shows the pressure column, consisting of a cylinder widening into the rectangular head A, in which is planed a groove to receive the first fulcrum a, into which it is pressed, aod which is also pressed into similar grooves at its upper end in the first lever B. A fixed fulcrum, d, is pressed at its lower end into the lever B, and its upper end into a groove in the fulerum block D. The third fulcrum 6 is shown clamped at the outer end by a | cClamping-plate, and its upper end is pressed | into the lever C, or into a block attached to lthe lever C. The same bluck clamps the | fourth fulerume to its lever C. Tbe ful }crums d and ¢ are both fixed, which causes | the lever B to move upward at ils upper outer end, as shown by the arrow, and the lever C to move downward at the |}same time. The strain on the first four fulcrums a, d, b, c, is compression, while }that on the fulcrum e and f is tension r'hese fulerums are aJl of tempered plate steel, and are often gold plated, to pre } vent rusting. In the illustration shown, amount thick fulcrums 1s the pressure on the block A may }to 4000 or 5000 pounds, and the ness of the tirst and second from .04 to .v§ inch and the third and fourth fulc:ums 6 and ¢, .o2 inch Lhe | width of these is 4 inches, and the exposure or portion left free between the different levers is about .2 inch for a and «& and Be inch for 6 and 2 inches for c, the loads on the latter being reduced to about | 400 pounds through the lever B. Fig 1 is an enlarged view of the pres shown in Fig. 9. This hydraulic gauge is | for measuring loads of 7500 pounds to the sure yauye square inch. Surprising as it seeuis at first ight, the motion of these levers, thoug jtirmly connected in this way and transmit jting strain without the possibility of back | lash, is practically frictionless A further application of this form of ful }crum is shown in Fig. 12, where the beavy lines b,c andd represent pieces which, as we have said, take the pluce of the ordi nary knife edge Here the beam B re its load from the pressure column A through celves the fulcrums 6 and ¢ These are connected tu sther by the block ¢, for the purpose of int oes ing or allowing for a certain amount of lateral motion around the center of mo tion in the fulcrum 6 I'he beam 1s pre vented fre mi y ielding bodily to the stress by the fulcrum d, held in the fulerum bock D As its outward end moves up or duwn, mo tion is transuutted to the indica or rod Gi by are the (Cont ni ee _—_ s " Ps es ?. re 4 , ** SI cate eet te on L > a uaa eee Ls a x ” Re 2 THE IRON AGE.

HOGAN,|~ (Continued from Page 1.) means of the two suspension fulcrums E and F. Their action on the point of support of the indicator rod G is similar to what is shown in Fig. 7, which is, however, from another piece of apparatus, and this con- struction is intended to permit a large range of motion. We may here point out a de- cided difference in the twoconstructions. In Fig. 12 the bending of the fulcrums e and f is | directly as the angular motion of the indi- cator rod G, while in Fig. 7 the bending of the fulerums B and B? is constant, no matter | what the angular motion of the indicator rod C may be. This construction is often em- ployed by Mr. Emery where it is necessary to hang one beam from another, and where it is desirable to obtain great angular mo- tion. Fig. 8 illustrates the method of clamp- ing suspension fulcrums similar to E or F in Fig. 12. It must be observed, however, that in Fig. 12, the fulerums being very long and delicate, it is found desirable to protect the central portions, and this is dove by a pair of clamping plates. From the end of the Emery Scales and Testing "Machines, Built by the Yale & Towne Mfg. Co., Stamford, Indicator-Rod and 7.—An / Conn.—Fig. Fulcrums. | beam B a poise rod and weight plate K are }hung by a pair of thin plates, which illus- | trate another application of this kind of ful- |crum, giving all the lateral motion and flexi- bility which is needed, and preserving the exact fulcrum distance without wear or friction. The thickness of metal used for supporting the beams is very slight, and it would surprise most engineers to know that a piece of metal .y inch thick and 5 or 6 inches long, and perhaps 2 inches “ ex- | posure,” or portion not in, but between, the groove, will carry many thousand pounds without suspicion of buckling or springing. For those bearings or primary fulcrums | which are to take the heaviest pressures in the large gauge, the strips of metal are of the finest spring steel, ,\; inch in thickness and 4 inches in width, and are pressed into their grooves with a load of 18,000 pounds, though in use they would receive 4000 or 5000 pounds The greater portion of this metal is, as the reader will from the different drawings, firmly fixed in slots cut in the beams. When tensile strain is to come upon these fulcrums, of course a much thinner spring and a longer one is possible, and, with the construction shown in Fig 7, the angular motion can then be made as great as may be see Fig. 8.—Clamping Suspension Fulcrums. desired, and with the other construction it can usually be made as great as is necessary In many constructions the thickness of these fulcrums for compression is reduced to as lit inch, and for tension to as little t 16. inch. By increasing the width, the amount of strength obtained can be raised and any load whatever sup 1 tle as gso'55 = Sy indefinitely ported. Fig. 1 sh
