THE TALKING MACHINE WORLD. 51 LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS (Special to The Talking Machine World.) Washington, D. C, Feb. 8, 1913. Multiple Phonograph. Julius Roever, New York. Patent No. 1,049,923. This invention relates to improvements in multiple phonographs in which a wheel is used, the said wheel carrying on its circumference a series of records which are brought in turn or as desired beneath the reproducing mechanism. Machines of this kind are used in public places and are operated after dropping in a coin, and it is necessary and desirable occasionally to change the records and give a new list of pieces or tunes. The object of the present invention is to provide a device for supporting the records so that they may be easily and quickly changed, and so that when changed the machine may be assembled for operation again without any chance of jamming of the different parts so that there will be too much friction for the proper running of the mechanism. To this end is 'provided a rotatable record wheel carrying record holders near its periphery, the record holders being supported by the wheel only at one end of the holder and at right angles to the surface of the wheel. The records are changed by merely slipping them off and on the holder. In connection with the record wheel a disc rotatable is provided with the wheel and having cards or other means secured thereto indicating the name of the tune or piece of the corresponding record on the wheel, and an indicator set at a point where it is necessary to stop in order to have a desired record brought under the stylus of the reproducer. Figure 1 is a 'broken front elevation of a machine showing improvements, and Fig. 2 is a crosssectional view through the center and the upper part of the same. Tone Arm for Talking Machines. John C. English, Camden, N. J., assignor to the Victor Talking Machine Co., same place. Patent No. 1,049,348. This machine particularly relates to the means for connecting a sound reproducer with the swinging tone arm of a talking machine. The principal objects of this invention are to provide a simple and efficient mounting for connecting the tone arm and sound reproducer, which is co-operative with said arm when said reproducer is in operative position to afford a smooth, uninterrupted, continuous conduit for the free passage of sound waves ; and to provide a compact structure which when in inoperative position may be enclosed in a minimum space. Further objects of this invention are to provide such a pivoted connection between said tone arm and sound reproducer as to permit the free movement of said reproducer relative to said arm, effected by possibly slight irregularities in the record disc, and to permit the movement of said reproducer from said record to its inoperative position; to provide means carried by said arm to support said reproducer in an approximately operative position, independently of the turntable of said talking machine; to provide means to support said sound reproducer in its inoperative position at the side of said arm, and extending below the top thereof; and to provide means to automatically close said conduit when said sound reproducer is disposed in its inoperative position. The form of the invention hereinafter described provides a hollow tapered tone arm suitably mounted to swing on a substantially vertical axis, and having its free end curved laterally and terminating in a flanged collar, to which is pivoted a similar flanged collar on the tubular mounting, upon the free end of which the sound reproducer is removably attached. The flange of the mounting is provided with a lug or hook operative to engage suitably disposed lugs on the flange of said arm, and respectively arranged to support the sound reproducer in approximately operative position, and in its inoperative position. In the accompanying drawings, Figure 1 is a fragmentary sectional elevation of a talking machine, showing the tone arm carrying a sound reproducer in operative relation to a sound record disc; Fig. 2 is a fragmentary plan sectional view of the structure shown in Fig. 1 ; Fig 3 is a side elevational view of said tone arm supporting the reproducer in an approximately operative position, independently of the sound record disc ; Fig. 4 is a fragmentary view similar to Fig. 3, but showing the sound reproducer inverted to its inoperative position ; Fig. 5 is a plan view of the structure as shown in Fig. 4, exclusive of the casing; and Fig. 6 is a perspective view of the sound reproducer mounting per se. Recording and Reproducing Device for Phonographs. David H. Wilson, Chicago, 111. Patent No. 1,048,924. This invention relates to recording and reproducing devices for phonagraphs, and the like, and has for its object to produce a new and improved device of this description which may be used either as a recorder or a reproducer. Figure 1 is a side view of a device embodying the invention; Fig. 2 is a sectional view of the device shown in Fig. 1 ; Figs. 3, 4 and 5 show the parts of the device of Fig. 2 separated ; Fig. 6 is a sectional view showing a modified construction ; Fig. 7 is a view showing a further modification. Collapsible P h onograph Mich. Patent No. Horn. Gilbert Stiff, Ovid, 1,049,166. The invention provides a horn designed most especially for sound reproducing machines of the phonograph type, the purpose being the provision of a horn which will admit of its length being readily reduced so that the horn may be stored in a comparatively small space either for convenience of carrying or to be laid aside when not required for immediate use so as not to be in the way, the invention relating most essential'y to the joint formed between the horn sections whereby both the inner and the outer side of the horn arc practically smooth and continuous. Referring to the drawing, forming a part of the specification, Figure 1 is a side view of a horn of the type described embodying the invention, a part being broken away. Fig. 2 is a sectional view, the parts or horn sections being separated and the dotted lines showing the position of the sec tions when nested. Fig. 3 is an enlarged section of the point formed between adjacent sections. Fig. 4 is an enlarged view of a part of one of the horn sections. Phonograph Reproducer. Frank L. Dyer and Peter Weber, Orange, N. J., assignors by mesne assignments to Thos. A. Edison, Inc., West Orange, N. J. Patent No. 1,049,216 This invention relates to phonograph reproducers, the object being more particularly to provide for the greater freedom of movement of the stylus lever, in order that a more faithful reproduction of the vibrations of the sound record may be made, and that undue wear upon the stylus and record may be avoided. This invention relates more particularly to a novel means of mounting the stylus lever whereby greater freedom of movement of the same transverse to the record groove may be allowed. Another object of the invention is the provision of means for aligning the stylus lever in a central position whenever the stylus is lifted from the record surface. Figure 1 is a side elevation, partly in section, of a reproducer embodying the invention. Fig. 2 is a bottom view of the same showing the stylus lever and connections and the adjacent portion of the floating weight, and Fig. 3 is a detail view of the means for aligning the stylus lever centrally. Talking Machine. Frank L. Dyer, Montclalr, N. J., assigner by mesne assignments to .Thos. A. Edison, Inc., West Orange, N. J. Patent No. 1,049,215. This invention relates to talking machines, and the object is to produce an improved device for feeding the reproducer and stylus carried thereby across a rotatable \^"'' sound record of the disc type. The sound-co n v e y i n g tube upon which the reproducer is carried is mounted by means of a ball and socket joint upon a fixed tube forming part of or connecting with the amplifying horn. By this ball and socket joint construction the reproducer is free to be moved across the face of the record to give the feed, and also is free to be moved toward and away from the record surface. The movable hollow arm or tube carries a geared sector or other desired engaging means, which, upon the lowering of the reproducer to cause the stylus to engage a record, moves into mesh with a gear or other driving device connected with the motor. Thus, the feed may be engaged or dis(Continued on page 52.)
