Process of Making Records for Phonographs. William Sanderson, New York, N. Y. Patent No. 947,777. This invention relates to an improved process of making cylinder and disc records. FK , lu the drawings, { .J ■•'igure 1 is an ele vation of a disc made according to m 2 the invention in its preferred form, Fig. 2 is a section thereof prior to the molding operation, the several layers being exaggerated for clearance, and Fig. 3 is a similar view after the molding operation. Composition for Sound Records and Other Objects. John C. English, Camden, N. J., assignor to the Victor Talking Machine Co., same place. Patent No. 943,314. The object, therefore, of this invention is to produce such a composition or mixture for use in sound records and other objects which will not only have all the advantages of the mixtures of shellac and the different body materials which have heretofore been used, but will also have distinct advantages over the same, according to the inventor. Gum shellac, when in its purest form and highest grade, resembles well seasoned glue in consistency and color, and it is the aim of manufacturers of records to obtain shellac as near to this standard as possible. Of course, shellac when received by the users in the regular course of trade varies considerably in the texture and quality, and it has been the aim of the inventor to provide an ingredient or substance which will not only improve the texture and quality, but will reduce the shellac to a uniform grade. It has been found that by adding certain hydrocarbons to gum shellac that this result is produced in an extremely economical and satisfactory manner. Furthermore, different earthy materials, such as fossil flour, clay, powdered silica, metallic oxides, and other cheap earthly material and pigments, require greatly varying amounts of shellac to produce the requisite adhesive purpose and toughness to the composition. In the use of the improved composition and embodiment of these materials provides a much more uniform quantity of the binder heretofore attained by gum shellac. The o hj e c t, therefore, of this invention is to generally improve the material from which sound records and other obj e c t s requiring material having the same characteristics are made. In the drawing forming a part of this specification is illuitrated a sound record tablet of the disc type with the np.mes of the ingredients inscribed thereon, although it is obvious that the intention is not limited to any particular shape or type of tablet. Record Plate for Graphophones and Like Machines. William C. Rhodes, Cleveland, 0. Patent No. 946,563. This invention relates to record plates for graphophones and like machir.es. In the accompan ying drawing-, Figure 1 is a plan view of the plr.te or disc, and Fig. 2 is . a central cross! \ iff section theieof. stylus needle with respect' to its stylus bar. Referring to the drawings: Figure 1 is a plan view of a talking machine having the improvements embodied therein. Fig. 2 is a side Phonographic Recording Apparati rs. Thoma; A. Edison, Llewellyn Park, Orange, N. J., assignor to the New Jersey Patent Co , West Orange. N. J. Patent No. 950,226. This invention relates to various improvements i i phonographic recoiding apparatus, and the object is to provide an apparatus for the purpose, whsrein superior results can be obtained. It is found that vibrations of abnormal amplitude, caused by very high, shrill tones, like those of a soprano voice, or resulting from abnormal reinforcements of certain tones by the tone due to the resonance of the air column in the funnel, result in the cutting stylus leaving the record surface, producing the disagreeable effect of blasting. This result is due to the fact that the diaphragm in vibrating toward the record surface encounters the very considerable resistance imposed upon the stylus in effecting the cutting of the material, while In vibrating in the opposite direction, the diaphragm encounters little or no resistance. Consequently, under the effect of condensations of sound waves, the movement of the diaphragm is limited, while under the effect of the refraction of sound waves the movement of the diaphragm becomes abnormal and permits the stylus to jump free of the record surface. The accompanying drawing illustrates a sectional view of a recording mechanism equipped with the improved compound spring. Talking Machine. John B. Browning, Kansas City, Mo., assignor to Victor Talking Machine Co., Camden, N. J. Patent No. 948,040. The objects of this invention are to provide in a talking machine a plurality of sound boxes arranged to reproduce either simultaneously or separately the same tones from a single record, and to arrange the said boxes so that the operator is enabled to change the volume and quality of the sound at will, by raising one box, while the other continues playing: to provide means whereby a pair of independent sound boxes may be supported by a single sound tube; to provide an improved mounting for a diaphragm; to provide an improved mounting for a stylus bar; to provide means for the lateral adjustment of a elevation of the same. Fig. 3 shows an enlarged plan and end view of one of the U-shaped tubes as used in this device. Fig. 4 is a half section and half elevation of the tee connection. Fig. 5 is an end view of one portion of said tee. Figs. 6 and 7 aie front and sectional views, respectively, of one of the couplings. Figs. 8, 9 and 10 are side, central sectional, and bottom views, respectively, of one of the reproducers, and Fig. 11 is a diagrammatic view of the spring used in this device. Graphophone. Baxter Morton, New York, assignor by Mesne assignments to Hawthorne & Sheble Manufacturing Co., Philadelphia. Pa. Patent No. 848,959. This invention has for its object the provision of a graphophone in which the reproducer is not impelled across the record tablet by means of the record groove or by mechanical feed mechanism such as a screw or rack. In the accompanying drawings forming part of this application is illustrated the invention as embodied in a graphophone of the disc type, the stylus of the reproducer being yieldingly propelled across the record in a plane parellel to the surface of the disc with the stylus tracking in the record groove and restrained against too rapid movement thereby. In the drawing, Figure 1 is a view in side elevation of a complete graphophone embodying the present invention. Fig. 2 is a view partly in elevation and partly in section of the reproducer, the reproducer carriage and a portion of the record tablet and support therefor. Duplex Reproducer fob Phonographs. Frank P. Beck. Richmond, Va. Patent No. 950,428. This invention relates to duplex reproducers for phonographs, and one of the principal objects of the same is to provide means for con veying compressed air through the sound box and up into the outlet horn. Another object of the invention is to provide
