CHAPTER XXII.

THE PHONOGRAPH. INVENTION OF PHONOGRAPH BY EDISON--SCOTT’S PHONAUTOGRAPH-- IMPROVEMENTS OF BELL AND TAINTER--THE GRAPHOPHONE--LIBRARY OF WAX CYLINDERS--THE GRAMOPHONE. Following closely upon the discovery of the telephone the phonograph came, literally speaking for itself, and adding another surprise to the wonderful inventions of that prolific period. It was in the latter part of 1877 that Thomas A. Edison showed to a few privileged friends a modest looking little machine. He turned the crank, and to the astonishment of those present it said. “Good morning! How do you do? How do you like the phonograph?” Its voice was a little metallic, it is true, but here was presented an insignificant looking piece of mechanism which was undeniably a talking machine and one with an unlimited vocabulary. So-called talking machines had been made before, of which the Faber machine was a type. These, by an arrangement of bellows to furnish air, and flexible pipes in imitation of the larynx and vocal organs, made laborious and wheezy efforts to imitate the mechanical functions of the throat and tongue in articulate speech, but the method was fundamentally faulty and no success was attained. Edison followed no such leading. His phonograph made no attempt at imitating in construction the complex organization of the human throat, but was as wonderful in its divergence therefrom and in its simplicity as it was in the success of its results. The machine was patented by him Feb. 19, 1878, No. 200,521, and its life principle is simply and clearly defined in the first claim of the patent, as follows: “The method herein specified of reproducing the human voice, or other sounds, by causing the sound vibrations to be recorded substantially as specified, and obtaining motion from that record as set forth for the reproduction of sound vibrations.” The invention was a striking and interesting novelty and at once attracted the attention of scientific men as well as the general public. Its first public exhibition was about the latter part of January, 1878, before the Polytechnic Association of the American Institute, at New York. It spoke English, French, German, Dutch, Spanish and Hebrew with equal facility. It imitated the barking of a dog and crowing of a cock, and then catching cold, coughed and sneezed and wheezed until it is said a physician in the audience proposed sending a prescription for it. It was also suggested by an irreverent man that it might take the place of preachers in the rendition of sermons, while another thought that as it reproduced music with equal facility it might take the place of preacher and choir both. In the spring of 1878 it was exhibited at Washington by Edison and his assistant, Mr. Batchelor. Mr. Edison was the guest of Mr. U. H. Painter, and in his parlors it was shown to a party of gentlemen. From Mr. Painter’s house the machine was taken to the office of the Assistant Secretary of the Interior, thence to the Academy of Sciences, in session at the Smithsonian Institution, and at night it was taken to the White House and exhibited to President and Mrs. Hayes. [Illustration: FIG. 189.--FIRST PHONOGRAPH.] The form of the first phonograph is shown in Fig. 189. It consisted of three principal parts--the mouthpiece A, into which speech was uttered, the spirally grooved cylinder B, carrying on its periphery a sheet of tin foil, and a second mouthpiece D. The cylinder B and its axial shaft were both provided with spiral grooves or screw threads of exactly the same pitch, and when the shaft was turned by its crank its screw threaded bearings caused the cylinder to slowly advance as it rotated. The mouthpiece A had adjacent to the cylinder a flexible diaphragm carrying a little point or stylus which bore against the tin foil on the cylinder. When the mouthpiece A was spoken into and the cylinder B was turned, the little stylus, vibrating from the voice impulses, traced by indentations a little jagged path in the tin foil that formed the record. To reproduce the record in speech again, the mouthpiece A was adjusted away from the cylinder, the cylinder run back to the starting point, and mouthpiece D was then brought up to the cylinder. This mouthpiece had a diaphragm and stylus similar to the other one, only more delicately constructed. This stylus was adjusted to bear lightly in the little spiral path in the tin foil traced by the other stylus, and as the tin foil revolved with the cylinder its jagged irregularities set up the same vibrations in the diaphragm of mouthpiece D as those caused by the voice on the other diaphragm, and thus translated the record into sounds of articulate speech, exactly corresponding to the words first spoken into the instrument. In Fig. 190 is shown a further development of the phonograph, in which a single mouthpiece with diaphragm and stylus serves the purpose both of recorder for making the record and a speaker for reproducing it, a trumpet or horn being used, as indicated in dotted lines, to concentrate the vibrations in recording and to augment the sound in reproducing. [Illustration: FIG. 190.--SECOND FORM OF PHONOGRAPH.] The phonograph is in reality a development of the phonautograph, which was an instrument invented by Leon Scott in 1857 to automatically record sounds by diagrams. There is a model of Scott’s phonautograph in the National Museum at Washington, D. C, and it consists of a chamber to catch the sound waves and an elastic diaphragm with stylus working on a revolving cylinder bearing a sheet of paper coated with lampblack. The phonograph’s record-making mouthpiece, with its diaphragm and stylus, is substantially a phonautograph, but instead of simply causing the stylus to trace a record on carbon-coated paper and stopping with this result, Edison traced a record in a substance--tinfoil--which was capable of mechanically translating that record into sound again by a mere reversal of the function of the stylus and diaphragm. This was the very essence of simplicity and logical reasoning. All records had been heretofore traced for visual inspection only. Edison’s record was not for visual inspection, but was endowed with the mechanical function of reproducing sound. From the first Edison believed that his phonograph was to fill an important place in the business activities of the world, since here seemed a silent but faithful stenographer which reproduced the words of the speaker with absolute fidelity, even to the quality of emphasis and inflection, and which made no mistakes, was always even with the speaker in its work, and asked no questions. For a number of years, however, the invention lay dormant and served no other purpose than that of a scientific curiosity or an amusing toy. The difficulty of its practical application largely existed in the perishable form of the record, which, being in tinfoil, was liable to be mutilated and distorted, and was not well adapted for storage or transportation. A few years after the announcement of Mr. Edison’s invention. Dr. Alexander Graham Bell, the distinguished inventor of the telephone, with his associates, Messrs. Chichester A. Bell and Charles Sumner Tainter, directed their attention to the improvement of the phonograph. Dr. Bell had received from the French government, upon the recommendation of the French Academy of Sciences, the Volta prize of 50,000 francs as a recognition of his successful work in acoustics and the invention of the telephone, and with this sum he built the Volta Institute in Washington and carried on the work of developing the phonograph. On May 4, 1886, Chichester A. Bell and Sumner Tainter obtained patents Nos. 341,214 and 341,288, which covered a great improvement in the record of the phonograph. This invention substituted for the tinfoil sheet a surface of wax, which was finally fashioned into a cylinder, and instead of merely indenting the record on tinfoil the stylus cut a distinct groove or kerf in the wax cylinder as it revolved, dislodging therefrom a minute filament or shaving and forming a record which was not only far more positive in its translating effect and more easily transported and stored, but was also less perishable, and besides it could be easily effaced without loss of the cylinder by simply smoothing off the surface of the cylinder again when it was desired to make a new record. This invention quickly grew into practical use, and is known as the “Graphophone.” [Illustration: FIG. 191.--THE GRAPHOPHONE, RECORDING AND REPRODUCING DEVICES.] In Fig. 191 is shown on the left a cross section of the diaphragm, recording stylus, and wax cylinder, of the graphophone, the stylus plowing a tiny groove in the wax cylinder in the act of recording the speech, and on the right is shown the reproducing stylus traversing the record groove in the wax cylinder, and the diaphragm chamber with which the ear tubes are connected. The grooves in the wax, although giving forth mechanical movement that is translated into sound, are very minute, being only 6/10,000 of an inch deep. When the possibilities of the graphophone became known, capital was quickly supplied for its commercial exploitation, and the Columbia Phonograph Company was organized. At the present time, owing to the great increase in the business, the control of the graphophone business is vested in two branches, the Columbia Phonograph Company, which has charge of the selling, and which has offices throughout all the principal cities of this country and some of the larger ones of Europe, and the American Graphophone Company, which attends to the manufacturing branch, and whose factory is located at Bridgeport, Conn., where, it is said, that in 1898 the production of the factory reached the point of one graphophone for every minute of the day, making a total daily output of 600 machines. Although the Bell and Tainter patents of 1886 represent the basic principles of the graphophone, its development and perfection have been contributed to in many subsequent improvements by Messrs. Bell, Tainter, McDonald, and others. The more important of these are covered by patents No. 375,579, Dec. 27, 1887; No. 380,535, April 3, 1888; No. 527,755, Oct. 16, 1894, and No. 579,595, March 30, 1897. At the beginning of this industry it was thought that the principal use of the instrument would be found in business applications, to take the place of the stenographer, but it proved difficult to revolutionize office methods, especially as the earlier machines were somewhat intricate, and the business man had no time to divide in engineering a machine. These difficulties, however, have been so far overcome by modern improvements and simplification of the machine that its use in business houses as an amanuensis has become quite common. The greatest use of the graphophone is, however, for amusement purposes. Its songs, orchestral and solo renditions, and its humorous monologue reproductions constitute to-day a great library of wax cylinders, regularly catalogued and sold by the thousands. It will readily be understood that the formation of the cylinders must constitute a great business of itself when it is remembered that many record cylinders accompany each graphophone, and that the latter are turned out at the rate of one a minute by a single company. Many thousands of these cylinders are made daily. Some are sent out simply as plain wax cylinders, onto which the records are made by the voice of the purchaser, while others have records made for them of popular music, monologues in dialect, humorous speeches, etc. The waxy composition, which is in reality a species of soap, is melted in huge pots, and then passes from one floor to another, undergoing a refining process in its progress, and finally reaches the molds. These molds are arranged in rows around a horizontal wheel about eight feet in diameter. The wheel is kept revolving, and a man on one side is kept constantly busy in filling the molds with the molten material as they reach him. A half revolution of the wheel brings the filled molds to the other side of the room, and by that time the material has hardened sufficiently to enable another attendant, stationed there, to remove the cylinders from the molds. Thus the wheel is kept going, receiving at one side a charge of the melted wax and discharging at the other molded cylinders, which are afterwards turned true on the surface. The record-making department is both unique and interesting. Here the records of music are produced, and they are made by bands and performers engaged for the purpose, many of which, operating at the same time, produce such a medley as to be scarcely distinguishable to the visitor. The records are tested by about half a hundred women, each of whom has a little compartment or booth framed in by glass partitions. The duty of the tester is to decide upon the merits of the record by actually listening to it on the graphophone. A very important feature in record-making, from a commercial standpoint, is in means for cheaply duplicating records. If every record cylinder had to be made by the separate act of a performer such records would be very expensive. An original record is first made by some celebrated musician or speaker, and this record is afterwards multiplied and reproduced in large numbers. For this purpose an original record by suitable mechanism is made to take the place of the speaker or singer, and so multiplies and reproduces the original record. The duplicating of records was contemplated by Edison from the first, as seen in his British patent, 1,644 of 1878, and later appliances for accomplishing such results are covered under Tainter’s patent, No. 341,287, Bettini’s, No. 488,381, and McDonald’s, No. 559,806. The diaphragms used in the recorders and reproducers are made of French rolled plate glass, thinner than a sheet of ordinary writing paper. The recording stylus is shaped like a little gouge to cut the little grooves in the wax, while the corresponding stylus of the reproducer has a ball-shaped end to travel in the groove. Both the recording stylus and reproducing ball are made of sapphire, chosen on account of its hardness, to resist the great frictional wear to which they are subjected. When a record is to be effaced from a cylinder, it is turned off smooth on a sort of lathe, and the cutting tool or knife for this purpose is also made of sapphire. The latest, loudest, and most impressive form of the talking machine is the “Graphophone Grand.” This has a horn attachment exceeding the big horn of a brass band in size, and the wax cylinder is about four inches in diameter. Its reproductions in music and speech are so full and strong as to be clearly heard at the most remote part of a large hall, and its versatile voice lends effective rendition to all sorts and kinds of sounds, from the inspiring chords of “A Choir Invisible” to the grandiloquent and facetious rattle of a noisy and hustling auctioneer. [Illustration: FIG. 192.--MODERN PHONOGRAPH.] It is not to be understood, however, that the graphophone is the only speaking machine on the market, for about 250 patents have been granted on phonographs and graphophones. The National Phonograph Company, under many later patents granted to Mr. Edison, manufactures and sells the phonograph shown in Fig. 192, which is a very ingenious and effective instrument. This modern form of phonograph is actuated either by electricity or spring power, is regulated by a speed governor, and bifurcated ear tubes connect with the diaphragm case, which tubes are placed in the ears when the instrument is operated. [Illustration: FIG. 193.--THE GRAMOPHONE RECORDER.] The gramophone is also another speaking machine. This is the invention of Mr. E. Berliner and covered by him in patent No. 372,786, Nov. 8,
