The talking machine world (Jan-Dec 1906)

26 THE TALKING MACHINE WORLD. LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS. (Specially prepared for The Talking Machine World.) Washington, D. C, Marcli 7, 1906. Phonograph. Eugene M. Robinson, Chicago, 111. Patent No. 813,670. This invention relates to phonographs, and particularly to means for reducing the volume of scund-waves passing through the horn of the phonograph, whereby a phonograph designed for outdoor work or for a large auditorium may be used in a small room without discomfort to the auditors. This invention is in some respects an improvement upon patent No. 778,271, for phonograph, issued to same party December 27, 1904. The object of this invention is to provide modified forms of structure for use in place of those shown in prior patent. One of these forms is especially designed for use in a well known com mercial type of phonograph-horn, whereby great accuracy of regulation of the volume of soundwaves passing through the horn is obtained. This invention consists in this particular detail in the use of a horn having a substantially rightangled joint therein, there being in one of the angular portions of this horn a rotable valve adapted to be rotated from without to regulate the volume of sound-waves passing from one of the angular portions of the horn to the other. The invention also consists in the novel form of mounting for a sound-restricting mechanism, so that it can be detachably placed in the horn at some suitable point between the reproducer and the end of the horn. In the drawings. Fig. 1 is a side elevation of one of the commercial forms of phonograph hav ing preferred form of the invention applied thereto. Fig. 2 is a plan view of the same, a portion of the horn being removed. Fig. 3 is a sectional detail view showing the preferred form of invention in assembled position. Fig. 3a shows an alternative form of valve. Figs. 4, 5 and 6 are sectional detail views of different parts of the structure of Fig. 3. Fig. 7 is a plan detail view showing means for restricting at two different points the volume of sound passing through the horn. Fig. 8 is a sectional detail view of the left-hand arm of Fig. 7, showing in detail a mounting for the restricting mechanism, which mounting can on a proper proportioning of the parts be applied to the horn at any desired point in its length. Fig. 9 is a detail plan view of the exterior of the mounting just referred to. Fig. 10 is a rear view of a reproducer, showing the method of attaching the mounting of Fig. 9 thereto. Fig. 11 is a plan detail view showing two means for restricting the volume of sound passing through the horn at different points, one of said means being practically within the reproducer itself. Fig. 12 is a detail sectional view on line 12 of Fig. 11. Fig. 13 is a sectional plan view taken on line 13 of Fig. 12. Fig. 14 is a sectional detail view taken on line 14 of Fig. 12. Geamophoxe. Herbert S. Mills, Chicago, 111. Patent No. 812,512. This invention relates to an improvement in the means for supporting the stylus in the form of an attenuate length of wire on the reproducer of the instrument to co-operate with the rotary recorddisc, the degree of attenuateness of the wire, which is of uniform or substantially uniform thinness throughout, being such as to cause it to present always to the record-grooves an adequately fine point as it wears away with use by fric One Thousand CYLINDER RECORDS That's the Capacity of THE MONARCH Revolving Rack You cannot carry records as well any other way. We can hardly keep pace with the demand. Better gel your order in ISJOW Catalogue of the complete "Heise System" of racks on application. Shall we send it ? Syracuse Wire Works SYRACUSE, N. Y. tional contact with the grooves. This fine wire is too yielding for use without support, since by undue bending in traversing the disc it wears the record and renders it indistinct. The object of this invention is to provide a novel construction of rigid clamp on the reproducer which shall serve to hold the wire in a manner to permit one end to protrude to the desired short distance beyond the clamp for engagement with the record and to confine the wire throughout the remainder thereof contained in the clamp, so firmly and uniformly as to render it practically an integral part of the rigid clamp, and thus prevent any independent vibration or movement of the wire therein which would tend to mar or destroy the stylus action. In the accompanying drawings. Fig. 1 is a broken view showing in side elevation the reproducer equipped with the improvement and in operative position relative to the record-disc. Fig. 2 is a view of the reproducer in front elevation, shown broken and provided with the improvement. Fig. 3 is a section taken at the line 3 on Fig. 1 viewed in the direction of the arrow and enlarged: and Fig. 4 shows the parts of the improved clamp separated and ready to be assembled, the removable jaw being in section and the other parts in elevation. Graphophoxe-Reproducer. Geo. A. Mainwaring, Bayonne, N. J., assignor to American Graphophone Co., Washington, D. C. Patent No. 811,568. This invention relates to means for securing in place the needle of a reproducer, and its purpose ia to permit the needle to be readily inserted in place and to expedite the substitution of a fresh needle for an old one. At the present time these needles are held in the needle receiving barrel by a set-screw, and to put in a fresh needle the screw has to be turned several revolutions, and then after the old needle is removed and the new needle put in place the screw has to be turned back several revolutions, all of which calls for considerable time and trouble. By means of this invention most of this is avoided. The use of a split spring-socket for holding the needle has also been proposed; but no means (such as a lever) have been provided for releasing the pressure upon the needle to permit ready removal of the same and substitution of a fresh needle. This invention will best be understood by reference to the accompanying drawings, showing the preferred embodiment thereof, in which Fig. 1 is a face view, and Fig. 2 is a side view, partly broken away, of a reproducer equipped with this novel means for holding the needle in place. Fig. 3 is a sectional view through the barrel of the stylus-bar on line 3, Fig. 4, the stylusclamping lever being shown in elevation. Fig. 4 is a longitudinal sectional view at right angles to Fig. 3. Attachment for Phonographs. Zenas Tarble Grover, South New Berlin, New York. Patent No. 811,633. This invention relates to certain improvements in phonographs, graphophones and similar soundproducing machines, and more particularly to a
