56 THE TALKING MACHINE WORLD. LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS (Specially prepared for The Talking Macliine World.) Washington, D. C, Oct. 4, 1906. HoRX. Charles R. Breen, New York. Patent No. 829.836. This invention is an improvement in talliing machine horns, and the object of the invention is to produce a superior horn or trumpet to those hitherto devised — one which is highly resonant, but devoid of the objectionable metallic sound so often encountered in devices with a like object in view. Another object of the invention is to so construct the horn as to have a removable outer section which may be wrapped about the small end of the horn in order that the whole may be packed in a small compass. Fig. 1 is a partly sectional side elevation of one embodiment of this invention. Fig. 2 is a partly sectional side view showing the removable section detached and wrapped about the small end of the horn, and Fig. 3 is a perspective view of the removable section. Pho>-ograph Attachment. James Vincent Cruso, Newark, N. J., assignor of one-half to Thomas J. Hinton, same place. Patent No. 829,848. This invention relates to an improved phonogi'aph attachment, and has for its object to provide a device by which the ordinary cylinder record operating machines may be employed for operating a disc record, and thus adapting the one machine to both forms of records. Fig. 1 is a perspective view, illustrating the improvements applied to the ordinary cylinder record machine. Fig. 2 is a sectional elevation of the same. Fig. 3 is a detail view showing the horn supporting device. Fig. 4 is an enlarged sectional face view of a machine having my invention applied. Fig. 5 is a detail view illustrating the reproducer and the manner in which it is secured to the supporting lever. Fig. 6 is a detail section of the same drawn on the line 6 6 of Fig. 5, and Fig. 7 and Fig. 8 are detail views of the reproducer, showing the form of stylus holder employed, and Figs. 9, 10, 11 and 12 are detail views of the stylus holder, Fig. 11 being of the blank of which a portion of the holder is made. Phoxogbaph Tone Regclator. Eugene M. Robinson, Chicago, 111. Patent No. 831,188. This invention relates particularly to means for reducing the volume of sound-waves passing through the horn of the talking machine, whereby a machine designed for outdoor work or for a large auditorium may be used in a small room without discomfort to the audience. This in vention is in some respects an improvement upon patent No. 778,271", and Serial No. 251,470. As shown in Figs. 11, 12. 13 and 14 of the latter, this invention consists in the use of a valve in the sound conveyer consisting of a sheet or plate of imperforate material so mounted adjacent to an opening in the side of some portion of the sound conveyer that it can be moved to a po-ition in which it lies crosswise of or obstructs the sound-wave passage of the sound conveyer. In its preferred form the invention consists in the use of such a plate valve in combination with a novel form of mechanism for moving the plate of the valve backward and forward between opened and closed positions. More in ' detail, this invention consists in an article of manufacture comprising a plate with a hole in it, with a valve plate mounted in a re cess in said supplemental plate to close said hole, the whole being so constructed that it may be inserted at some convenient point in the sound conveyer of the phonograph. Referring to the drawings, Fig. 1 is a plan view of a portion of a phonograph corresponding, except as to the mechanical means for moving the valve plate, to Fig. 11 of said prior application. Fig. 2 is a sectional plan view through the reproducer and valve plate operating mechanism, taken on the horizontal central plane of Fig. 1. Fig. 3 is a detail sectional end view taken on line 3 of Fig. 2. Fig. 4 is a side view of the valve mechanism proper removed from the phonograph. Fig. 5 is a side view of the simplest form of my mechanism, the same being identical with Fig. 12 of said prior application. Fig. 6 is a horizontal sectional view taken on line 6 of Fig. 5, the same being identical with Fig. 13 of said prior application. Fig. 7 is a detail view of a modified form of this invention in which the valve plate is pivotally mounted. Gramophone. Conrad Hilgenberg, Chicago. 111. Patent No. 831.344. This improvement relates to the gramophone "reproducer" and the connections with that part and the horns, and the object is to increase the volume of sound and improve the tone of the instrument. Fig. 1 is a side view of the gramophone, showing the reproducers, connections and horns in position supported by the bracket and VICTOR If of U R A Dealer TALKING MACHINES We will gladly mail U our New illustrated price list of EDISON VICTOR GENERAL SUPPLIES EDISON VICTOR We can save you from 30 to 60<r New and Halsey Sts.
