THE TALKING MACHINE WORLD. 67 LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS (Special to The Talking Machine World.) Washington, D. C, October 6. — Sound Box for Talking Machines. — Alva D. Jones, Philadelphia, Pa. Patent No. 1,142,883. This invention relates to a novel construction of a sound box for talking machines, graphophones and other sound recording and reproducing machines, and its object is to improve the construction of the recording and reproducing mechanism, particularly that part known as the sound box and stylus supporting bar, whereby the sound delivered from the diaphragm is greatly improved and a clear and distinct articulation obtained, provision being made for the diaphragm to be yieldingly supported in the box so that it has capacity for vibration adjacent to its perimeter as well as at its center, the sound box and its adjuncts being inexpensive to construct, sensitive in action, easily and quickly repaired and readily accessible for the purpose of inspection or replacement of parts, means being thus provided for a general improvement of the tones, amelioration of the scratchy metallic or grinding sounds common in instruments of this class and for developing the delicate sounds ordinarily difficult to reproduce. This invention further consists of a novel construction of stylus support embodying broadly the combination of a stylus and a convoluted or resident support therefor, whereby the requisite freedom of vibration in every direction is imparted to the stylus under all conditions to accommodate or compensate for all inequalities or depressions in the groove of the disc with which the stylus coacts, whereby there is produced a general improve ment of the tone reproduced and an elimination of the scratching and metallic harshness heretofore existing. Figure 1 represents a sectional view of a sound box embodying this invention. Fig. 2 represents a section on line x — x, Fig. 1. Fig. 3 represents a side elevation showing the stylus and its convoluted resilient support in detached position. Fig. 4 represents a front elevation of Fig. 3. ■Cabinet Sound-Reproducing Machine. — Henry C. Miller, Waterford, N. Y., assignor to Victor Talking Machine Co., Camden, N. J. Patent No. 1,146,342. This invention relates to improvements in soundreproducing machines. One of the objects of this invention is to provide a supplemental cabinet unit having a sound modifying chamber with a sound passage therethrough, said cabinet unit being associated with any of the well-known types of talking machines in order to vary the reproduced sound. The unit is so constructed that it may be readily associated with a talking machine or removed therefrom to permit said parts to be employed in conjunction with each other or to enable the talking machine to be used alone, according as desired. A further object of the invention is to provide a sound chamber having a sound passage therethrough and inclosing a plurality of spaced partition members which subdivide the interior of said chamber and act on the sound waves. Figure 1 is a side elevation of a cabinet unit partly broken away, and a talking machine of the Victor type associated therewith ; Fig. 2 is a plan view of one of the partition members employed in the cabinet unit; Fig. 3 is a similar view of another one of the partition members ; Fig. 4 is a view similar to Fig. 1, but illustrating the use of the cabinet unit with a talking machine having an exposed amplifier ; Fig. 5 is a plan view of a cabinet unit with still a further style of talking machine, the said unit being shown partially in section. Metallic Acoustic Diaphragm and the Manufacture Thereof. — Emanuel Aufiero, Brooklyn, N. Y. Patent No. 1,146,773. The invention relates to acoustic diaphragms such as are used in telephones, talking machines. and particularly in automobilists' signaling devices and the like. In the drawings Figure 1 indicates a diaphragm dented by hammer-blows in carrying out the invention ; Fig. 2 indicates, in exaggerated manner, a cross-section of a portion of a dented diaphragm, and Fig. 3 is a plan indicating a diaphragm upon which the invention has been carried out by the use of a die. Phonograph. — Clinton B. Repp, New York. Patent No. 1,146,519. This invention relates to phonographs, and more particularly to the means for transmitting sound vibrations from the record to the diaphragm. The main object of the invention is to provide a phonograph embodying therein a transmitting or vibrator member without a pivotal support intermediate the ends thereof, the ends of said transmitter or vibrator member being respectively adapted to apply pressure to the diaphragm and to support a producer point, the means applying such pressure permitting said member or arm to be projected over a disc record. A further object is to provide a phonograph wherein the sound vibrations will be transmitted from the record to the diaphragm through a transmitter or vibrator member and pressure will be exerted upon said arm at a single point to simultaneously tension the diaphragm and cause that intimate contact between the reproducer point and the record which is desirable to induce in said transmitter vibrations corresponding with all of the sound waves indicated upon a record. A still further object is to provide in conjunction with an apparatus having the characteristics referred to immediately above means for regulating the pressure exerted by the tensioning member or mechanism. A still further object is to provide a phonograph of this type wherein the tensioning means will exert a predetermined, proportionate pressure upon the reproducer point and upon the diaphragm. A still further object is to provide a phonograph of the character described wherein the pressure on the diaphragm may be varied without varying the pressure upon the reproducer point. A still further object is to provide a phonograph embodying therein a transmitter or vibrator member subjected to pressure acting toward the record and away from the diaphragm, by means of a rigid, swiveling controlling arm, said transmitter being connected to, or supported from, said controlling arm in a manner to avoid any interference with the vibrations passing through said transmitter or vibrator member, or the presence of a fulcrum about which said member oscillates in following the vertical undulations of the record. A still further object is to provide a phonograph of this character wherein the volume of reproduced sound may be augmented by merely adjusting the stylus or reproducer point. And a still further object is to provide a phonograph embodying therein a transmitter or vibrator member to which pressure is applied by a rigid controlling rod connected therewith in a manner to avoid interference with the free vibrations of said transmitter or vibrator arm or member, said controlling arm being free to have vertical movement with the undulations upon a record and to have lateral movement to permit the stylus or reproducer point to track in the spiral formed by the indicated sound waves of said record. Referring to the drawings, Figure 1 is a side elevation of a phonograph embodying the invention ; Fig. 2 is a detailed view, partly in elevation and partly in section, of the sound transmitter and reproducing mechanism only; Fig. 3 is a plan view of the transmitter or vibrator member and its o ntrolling and supporting arm, one end of said transmitter or vibrator member being broken away to disclose in detail the mechanism thereunder, and Fig. 4 is a front view of the forward end of the transmitter or vibrator member, illustrating the manner of attachment of said member to its controlling arm, and the details of the mount for the stylus or reproducer point. Phonograph. — Mzl Fuller, Birmingham, Ala. Patent No. 1,146,418. This invention relates to improvements in phonographs, or sound recording and reproducing apparatus, and its object is to simplify, lighten and condense the apparatus so that it may be embodied in a small, compact and portable structure which can be conveniently carried in the pocket. This present invention is especially adapted for use in connection with other inventions of Mr. Fuller the object of all of wtiich is to make it possible to conveniently and cheaply produce small, light records and reproduce from the same so that such records may be transmitted through the mails and interchanged to form a part of business and personal correspondence. With such an end in view, one important thing is to so simplify and cheapen the means of making and reproducing the records that they can be made generally accessible, and that is the object primarily in view in the present invention, which involves novel features in the construction of the casing or container for the recording apparatus ; the tone arm and manner of mounting the same and attaching the sound box thereto ; the arrangement and construction of the sound amplifying means ; the manner in which the operating mechanism is detachably mounted in the container, and the provision for carrying a number of record discs in the phonograph casing.
