180 THE TALKING MACHINE WORLD January IS, 1921 LATEST PATENTS RELATING ToTALKING RECORDS Washington, D. C, January 8. — Indicator for Phonograph Reproducers. Joseph Wolff, assignor to the Sonora Phonograph Co., New York. Patent No. 1,350,763. This invention relates to indicators for positioning the reproducers of talking machines. The objects are to provide visual means whereby the reproducing stylus may be placed in the proper position in the record groove, whereby the operator will not be compelled to watch the point of the stylus when starting the machine. Further objects are to provide an indicator which wall not interfere with the operation of the machine, and which, when not in use, will be practically concealed from view; to provide means to indicate the point in the record groove corresponding to the stylus position on said i ecord groove, and also the provision of means of the character described, simple in construction, inexpensive to manufacture and so designed and constructed that it ma3" be readily and easily attached to disc talking machines now in general use. Figure 1 is a plan view of a talking machine with the cover removed and with the invention applied. Fig. 2 is a rear elevation of a sound box with the invention affixed to the tone arm, and Fig. 3 is a similar view of a modification. Talking Machine. George H. Isley, Worcester, Mass. Patent No. 1,355,081. The present invention relates to talking machines, and more particularly to such machines which are adapted to play continuously, by the use of a multiplicity of records, the latter being brought progressively by mechanical means into position for playing by the tone-producing mechanism of the machine. The invention of the present application resides in certain improvements and refinements upon a machine of similar type which is shown and described in prior copending application Serial No. 108,342, filed July 10, 1916, Figure 1 is a plan view of a machine embodying the present invention, certain parts being broken away to disclose more fully the construction; Fig. 2 is a transverse sectional view thereof partly on the line 2 — -2 of Fig. 1, disclosing interiorly the operating mechanism of the machine; Fig. 3 is a central sectional view of the tone arm support and associated parts; Fig. 4 is a section on the line 4^4 of Fig. 2; Fig. 5 is a section on the line 5 — 5, Fig 2; Fig. 6 is a fragmentary detail view showing the governing mechanism of the machine, and Fig. 7 is a fragmentary detail view showing a modified cam construction. Controlling Means for Gramophones. Charles A. Fisk, Arrotsford, Quebec, Canada. Patent No. 1,354,961. This invention relates to improvements in means for controlling or regulating the tone and volume of sound produced by gramophones, and the object of the invention is to provide a simple, inexpensive, durable and easily adjusted means \ '3 / / IS 13 /" // \ Fig. 2 Fig / by which the sound produced by a gramophone may be regulated as to tone and volume. The device consists briefly of a horn which may be built into the casing of a gramophone or otherwise suitably located, having separate sounding boxes surrounding it. The tone arm of the gramophone leads into the horn and is provided with an adjustable diaphragm. Various sound regulating means may be mounted in the horn. Figure 1 is a vertical, longitudinal, sectional view of the device; Fig. 2 is a front elevation. Talking Machine Apparatus. Albert J. Swing and Albert S. King, Cincinnati, O. Patent No. 1,355,711. This invention relates to improvements in talking machines. One of its objects is to provide an improved combination of sound transmitting mechanism to preserve and transmit all of the sound reproduced by the diaphragm. Another object is to provide in combination with a transmitting diaphragm a horn or megaphone the inner end of which from a point close to the diaphragm is subdivided into a plurality of separate tubular compartments, and which merge into a common compartment at different points between the inner and outer ends of the horn. Another object is to provide an improved horn. Figure 1 is a diagram partly in section through a talking machine apparatus embodying the improvements; Fig. 2 is an enlarged sectional view of the diaphragm casing and tone arm detached; Fig. 3 is a cross sectional diagram through a modified form of tone arm divided into three compartments; Fig. 4 is a section on line v — v of Fig. 2; Fig. 5 is a section on line z — z of Fig. 2; Fig. 6 is a section on line x — x of Fig. 2. Apparatus for Recording and Reproducing Sound. Richard S. Arthur, New York. Patent No. 1,355,523. This invention relates more especially to the transmission of motion to the record, in sound recording and reproducing machines, so as to cause the same to travel beneath the stylus of the sound box, and the objects of the invention are to prevent the transmission of vibrations and tremors to the record from the driving apparatus, and thus improve the quality of the sound. It will be understood that in many sound recording and reproducing machines, and particularly the less expensive ones, there is considerable irregularity in the movement produced by the -motor, which is transmitted to the record, if the connection is a rigid one, and detrimentally affects the sound reproduction. The objects of the invention are to remedy this and to provide a resilient or yielding connection between the motor and the record which shall turn it with sufficient positiveness and at the same time absorb any slight irregularities, such as vibrations or tremors, and give the record a perfectly smooth and uniform motion; to do this simply and inexpensively, and to obtain other advantages and results as may be brought out in the following description. Figure 1 is an elevation of a cylinder machine of ordinary and well-known construction illus trating the application of the invention thereto; Fig. 2 is a section through the cylinder and record thereon. Reproducer for Talking Machines. John W. Kaufmann, Baltimore, M'd. Patent No. 1,354,197. This invention is an improvement in reproducers, and has for its object to provide a new and improved connection between the needle and the diaphragm controlling lever, which will eliminate the usual rigidity between these parts and which will intensify the movement of the needle during its transmission to the diaphragm of the talking machine. In the drawings: Figure 1 is a perspective view of the improved reproducer; Fig. 2 is a similar view of the holding bracket for the transmission member; Fig. 3 is a similar view of the diaphragm controlling lever; Fig. 4 is a perspec live view of one of the connecting brackets; Fig. 5 is a longitudinal section; Figs. 6 and 7 are views similar to Fig. 5, showing modified constructions; Fig. 8 is a side view showing a modified form of needle holder. Combined Table Light, Fan and Phonograph. Peter R. Gonsky, Detroit, Mich., assignor to the Endlessgraph Mfg. Co., New Jersey. Patent No. 1,359,053. This invention has for an object to provide a ,j.W9.oo3. construction in a stand and mechanism whereby the appliance may be used as a gramophone, fan and reading light combined, adapted to be set upon any suitable horizontal surface, and utilized for its various functions in an efficient manner, without interference of one with another. It is an important object to give a construction of this character in which the shaft for the rotating table of the gramophone may be employed to rotate and drive the fan, and an additional interposed
