The talking machine world (Jan-Dec 1911)

THE TALKING MACHINE WORLD. 55 LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS (Special to The Talking Machine World.) Washington, D. C, Dec. 7, 1911. Sound Reproducer. Alexander N. Pierman, Newark, N. J., assignor by mesne assignment to Thos. A. Edison, Inc., West Orange, N. J. Patent No. 1,010,311. This invention relates to talking machines of the type in which undulations corresponding to sound waves are impressed upon a current of any suitable moving fluid by the operation of a suitable valve through which the fluid is allowed or caused to pass, the valve being operated in accordance with the sound waves, as by connection with a reproducing stylus tracking a record groove. The objects of the invention are to construct a sound reproducer in which the moving fluid is caused to operate a sensitive valve of a novel character in a novel manner, whereby a sound reproduction of clear and excellent qualities and the desired degree of loudness or amplification is secured. The valve or vibratory member or' members constructed in accordance with this invention is of minimum mass, whereby defects due to inertia and momentum of parts are largely avoided. In accordance with these objects, thin, flexible, reedlike members are interposed in the path of the moving fluid current and are vibrated in accordance with sound vibrations to set up corresponding undulations in the moving fluid current in the sound box of the reproducer. In the preferred form of this invention a port plate is provided having one or more slit-like ports' therein, upon which ports are seated thin, flexible, reed-like members of elastic material which are placed under tension and secured to the port plate at both ends. Also, preferably, these jf^ij / reedlikc members are burnished or otherwise given such a conformation that they rest upon the mouths of the ports in close contact, partly within the same, to accurately close the said ports when the members arc in their normal position. The reedlike members are jciiiied together and are flexed by connection with the stylus to vary the extent .of opening of the ports to a greater or less extent in accordance with the sound vibrations which originally produced the record 55 groove tracked by the stylus. ■ Figure 1 is a side elevation, partly in section, of a sound reproducer embodying the invention. Fig. 2 is .a plan view of the port plate with the valve members secured thereto. Fig. 3 is an enlarged fragmentary cross section through one of the ports of the port plate showing one of the reed-like members burnished into contact therewith, and Fig. 4 is a detail view showing the preferred method of securing the reed-like members to the port plate under tension. Phonograph Horn. Peter Weber, Orange, N. J., assignor by mesne assignments to Thos. A. Edison, Inc., West Orange, N. J. Patent No. 1,010,338. This invention relates to phonograph horns of the type in which the flaring bell is made in a single piece which is separately united to the small end or body portion of the horn, and has been preferably embodied in a horn, the axis of which is curved so that tiie horn extends upward from the phonograph sound box and the mouth of the bell occupies substantially a vertical plane facing in the same direction as the phonograph, as described and claimed in application filed by the same inventor October 14, 1907, No. 397,283. The present invention also relates to improved means for flexibly uniting a horn of this character with the sound box of the phonograph. Figure 1 is a side elevation of a horn constructed in accordance with the invention and ap plied to a phonograph which is illustrated in dotted lines; Fig. 2 is a section on line 2 — 2 of Fig. 1; Fig. 3 is a detail plan view of the means for locking the bell to the body of the horn; Fig. 4 is a section on line 4 — 4 of Fig. 3; Figs. 5 and 6 are views similar to 3 and 4 of a modified locking device; Figs. 7 and 8 are similar views of another modification ; and Fig. 9 is a view similar to the lower portion of Fig. 1, ishowing a phonograph in which the nipple of the sound box extends vertically and showing a modified construction of coupling for connecting the lower end of the horn with the said nipple. Phonograph. Frank L. Dyer, Montclair, N. J., and Frank D. Lewis, Elizabeth, N. J., assignors by mesne assignments to Thos. A. Edison, Inc., West Orange, N. J. Patent No. 1,010,355. This invention relates to phonographs, and the objects thereof are to provide a novel and effective mounting for a phonograph horn or sound conveyor used in connection with a phonograph or other talking machine, and to provide an improved cabinet for a phonograph or talking machine having the horn mounted. Figiire 1 represents a front elevation of an improved cabinet having a phonograph and horn mounted therein. /'fO./ Fig. 2 represents a side elevation of the lower part of the cabinet or supporting means therefor, the upper portion of the cabinet being shown partly in section on line 2—2 in Fig. 1, and Fig. 3 is a detail showing the method of mounting the horn in Fig. 2, the same being an end view of th(j liorn with supporting means. Means for Automatically Arresting Talking Machines. Arthur E. Spencer, San Francisco, Cal., and Frank C. Thomas, Mifl Valley, Cal. Patent No. 13,305. Reissued. This invention relates to means for arresting the rotation of a talking machine automatically upon the stoppage of the sounds produced by the talking machine. The object of the invention is to provide a device for accomplishing this and which will not necessitate any change in the form or construction of the record itself or in the mode of using the talking machine. In the accompanying drawing. Figure 1 is a broken plan view of a talking machine equipped with this invention; Fig. 2 is a broken side view thereof; Fig. 3 is a detail cross section on the line 3—8 of Fig. 1; Fig. 4 is a detail vertical section on the line a— a of Fig. 1, showing the positions of the parts when the tone tube is elevated ; Fig. 5 is a similar view showing the positions of the parts when the tone tube is lowered to its operative position; Fig. 6 is a similar view showing the positions of the parts when the tone tube is also in the lower position but the pin has arrived at the end of the record. Phonograph Reproducer. Herman Wolke, Orange, N. J., assignor by mesne assignments to Thos. A. Edison, Inc., West Orange, N. J. Patent No. 1,007,407. This invention relates to phonograph reproducers, and has for its object the provision of an improved mounting for the stylus lever in order that the same may have great freedom of movement in tracking the grooves of the sound record, and in order that the defects due to inertia of the moving parts may be obviated. More particularly, the object of this invention is to provide a mounting for the stylus, which shall permit the latter to be used in connection with records having two hundred threads to the inch, and track the same faithfully and without injury to the record or the stylus. While the stylus mounted in the manner of the invention is equally well adapted for use in connection with records having one hundred or some other number of threads per inch, the requirement of great facility of movement of the stylus lever both in a direction parallel to and transverse to the record groove, is particularly important in the case of the two-hundrcd-thread^ecorJ~or other record having a great number of threads per inch, ^y^^^ _ owing to the thin walls between the record grooves, which might be broken down or jumped across by a stylus, the parts moving with which ■have considerable inertia, and owing to the character of the record grooves generally. A c c o rdingly, a stylus mounting of the least possible inertia is very desirable. This is provided for in the invention by providing a universal pivotal connection between the stylus lever and the member supporting the pivot, which member is preferably the usual floating weight well known in the art. In order to eliminate inertia and friction to~tRe least possible degree, this invention comprises a mounting for the stylus lever in which point friction is substantially substituted for the line friction usual in devices of this character.
