98 THE TALKING MACHINE WORLD LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS Washington, D. C, August 8. — Method of Making Phonographic Records. — Hagar H. Byron, Chicago, 111., assignor by mesne assignment of one-third to A. H. Adams, Ada E. Pickard and J. L. Jackson, same place. Patent No. 1,185,056." This invention has for its object to provide a new and improved method by which continuous records of any desired length may be made having one or more grooves corresponding with the sound waves to .be reproduced; also to provide for making such sound grooves by photography and thus make practicable the simultaneous making of sound records and photographic records on the same medium, such as a flexible film, thereby insuring perfect synchronism. In the accompanying drawings, Figure 1 is a vertical sectional view showing one form of apparatus that may be conveniently employed for photographing sound waves upon a continuous film and at the same time photographing views thereon; Fig. 2 is an enlarged detail, showing the face view of a portion of a combined phonographic and kinetographic record as made by such apparatus; Fig. 3 is an enlarged detail, being a partial vertical cross section on line 3 — 3 of Fig. 1; Fig. 4 is an enlarged detail, being a partial vertical section on line 4 — 4 of Fig. 3; Fig. 5 is a perspective view of the guide wheels and shaft, and Fig. 6 is a cross section of the finished record. Sound Reproducing or Recording Machine. — George H. Underhill, Boston, Mass. Patent No. 1,185,149. This invention consists in improvements in sound reproducing or recording machines, being particularly, though not exclusively, concerned with machines employing a plurality of records which are brought successively into operative relation with the sound recording or reproducing mechanism. Herein is illustrated one specific embodiment of the invention as applied to a sound reproducing or recording machine employing a feeding mechanism by means of which the records are singly and automatically transferred from a traveling magazine or holder into operative relation with the sound reproducing mechanism of the machine. Subsequently, after reproduction of an individual record, the latter is then automatically withdrawn from its operative position upon the machine and replaced in the holder, which then advances to bring a fresh record adjacent the machine. The new record is then automatically transferred to the machine, the stylus mechanism restored to its initial position, and the operations of the machine, which, during the interval of feeding the records on and off the holder have been suspended, are repeated as described. In the drawings, Figure 1 is a plan view of the machine; Fig. 2 is a sectional elevation of the record feeding mechanism taken on the line 2 — 2 in Fig. 3; Fig. 3 is a sectional elevation looking toward, the right, and on the line 3 — 3 in Fig. 2; Fig. 4 is a section on the line 4 — 4 in Fig. 5 looking toward the right and showing the feeding carriages; Fig. 5 is a plan view on an enlarged scale of the feeding mechanism with the traveling carrier removed; Fig. 6 is an elevation, partly diagrammatic, showing the tilting shelf and the control thereof; Fig. 7 is an enlarged cross sectional view of the phonograph, showing the phonograph feed and the tilting shelf in end elevation, and Figs. 8, 9 and 10 are diagrams of the circuit connections. Tone Varying Attachment for Reproducing Needles.— Richard H. Vesey, Denver, Col. Patent No. 1,185,266. This invention relates to improvements in means applied to the reproducing needles of talking machines and consists in equipping the needle holder with a number of pieces or blocks composed of substances varying in hardness or density, all of them preferably being of less density than metal of which the usual needle holder is composed. In the improvement the needle holder is simply extended, the extension consisting of a hollow part which may be integral with the ordinary needle holding member, within which hollow part is located a number of members of varying density or hardness as heretofore stated. These members are perforated to register with the recess or socket of the ordinary needle holding part. The needle, if relatively loud results are required, should extend into the metal socket or recess of the ordinary metal part. When it is desired to vary the tone by making it lower or softer, the needle is withdrawn from the metal socket so that its inner extremity shall engage one of the members of the improvement. As these members themsleves are of varying density or hardness', as many different primary or basic variations in tone may be obtained, as there are different members or substances employed. In the construction illustrated in the drawing there are shown three blocks or pieces, composed of different material from the metal holder, the said blocks or pieces also varying in density as compared with one another. Consequently four different primary tone variations may be obtained, one when the needle is in the socket of the metal holder, and others as the inner extremity of the needle is left within the other blocks or pieces of the improvement. Furthermore a great variety of sub-tone variations may be obtained by varying the distances which the needle pene trates any one of the said members. In order to vary the tone it is only necessary to adjust the needle by moving it outwardly or inwardly as may be required. In the drawing, Figure 1 is a perspective view of a sound reproducing machine of the disk type, the needle holder being equipped with the improvement. Fig. 2 is a detail view of a needle and needle holder likewise equipped. Fig. 3 is a similar view showing a slightly modified form of construction. Fig. 4 is a sectional view in detail showing the improvement applied to a needle holder of ordinary construction, the latter being indicated by dotted lines. Fig. 5 is a similar view showing a slightly modified form of construction. Figs. 6 to 9 inclusive are detail sectional views showing the improved needle holder construction with the needle in different positions of adjustment, the parts being shown on a larger scale than in the other views. Light and Sound Distributing Apparatus. — George E. Emerson, Newark, N. J., assignor by Mesne assignments to Emerson Phonograph Co., Inc., New York. Patent No. 1,185,987. This invention relates to light and sound distributing apparatus, and comprises means for producing sound waves, said sound waves coacting with the heat of light rays, produced by the appurtenances of the invention, and from which results a distribution of the said sound waves. The invention assumes the form of a piece of artistic furniture, and specifically comprises a sound producing apparatus coacting with the heat resulting from a source of light, preferably a lamp, the lamp generally consisting of an electric bulb, although other sources of light may be used. The lamp is positioned to coact with the sound waves produced by the apparatus without interfering with the vibrations thereof. Some of the forms in which the invention may be embodied are shown and described in this application, although the disposition of the elements shown, may be varied in numerous ways without departing from the invention. The source of light or lamp of the invention is surrounded by an envelop of heated air, the hottest layer being adjacent to the lamp, and the temperature of the layers decreasing with their distance from the lamp. The velocity of sound increases with the temperature of the transmitting medium, the velocity increasing at about the rate of 23.9 inches with one degree centigrade. The end of the sound wave nearest to the lamp travels faster than the portion more distant from the lamp. The direction of advance of the sound wave before entering the unequally heated mass of air surrounding the lamp is parallel to the axis of the lamp, and variably heated strata of air about the lamp cause a turning of the sound wave, so that the direction of advance thereof is diverged from the axis of the lamp, thereby producing a distribution of the sound waves. In the various forms of the invention shown and described, in which the source of illumination consists of a lamp within the sound duct or horn of the apparatus, the lamp is separated or stepped off from the latter, so that the advance of the sound waves is not obstructed. When a lamp shade is used it is preferably made of a translucent material that will reverberate from the effects of the sound waves impinging thereon, and thereby perform the functions of a sound horn. Referring to the accompanying drawings, Figure 1 represents an elevation and partial axial section of one form of the invention; Fig.
