The talking machine world (Jan-June 1923)

188 THE TALKING MACHINE WORLD June 15, 1923 Washington, D. C, June S. — Horn. Carl J. Schinitt, Brooklyn, N. Y. Patent No. 1,449,843. This invention has for its object to provide a horn adapted to influence a vibrating air column in such a manner as to increase the pleasurable sensation desired to be produced on the auditory nerves. Figure 1 is. a longitudinal vertical section through a phonograph horn and its enclosing cabinet. Fig. 2 a lateral section of the horn shown in Fig. 1 following approximately the center of the horn and showing the face of the attaching block; and Fig. 3 a top perspective of the upper edge and a portion of the top of the horn shown in Fig. 1 illustrating the nature of the wood from which the horn is made. Phonograph Reproducer. Albert B. Rehn, Philadelphia, Pa. Patent No. 1,452,094. This invention relates to phonograph reproducers, and it contemplates, first, an improved reproducer constructed so as to . interfere as little as possible with the delivery of the soundwaves into the atmosphere and so that at the same time, 'if the reproducer is pivoted to its support as is usual, it will stand in convenient relation to such support for the facile performance of its pivotal movements; arid, second, in such a combination of a sound-box of the class having opposite spaced upright diaphragms and a forked stylus device whose arms are in vibration-transmitting relation to the respective dia phragms that adjustment may be effected to vary the tension of the said arms and hence of the diaphragms. In said drawing Figure 1 is a side elevation of the first-mentioned form; Fig. 2 is a sectional view on line 2 — 2, Fig. 1; Fig. 3 is a plan of said form; Fig. 4 is an enlarged fragmentary transverse sectional view in the plane of a certain stud t appearing in Fig. 1; Fig. 5 is a side elevation of the second-mentioned form; Fig. 6 is a front elevation, partly in section, of the same, and Fig. 7 is an enlarged fragmentary sectional view of said second-mentioned form. Phonographic Apparatus. Henry P. Clausen, Mamaroneck, N. Y., assignor to Western Electric Co., Inc., New York. Patent No. 1,452,361. This invention relates to phonographic apparatus and the object is to prevent the irregular vibrations of the moving systems in the recording or reproducing machines from being communicated to the operating or operated member, according to whether the device is for recording or reproducing. In general, the invention provides for mounting the operating or operated member, such as a diaphragm, spaced from the stylus, and directly connecting it thereto by a longitudinally moving member, instead of the usual lever system. Specificallv, the invention provided for directly connecting the operating or operated member to the stylus when these elements are in spaced relation, by means of a longitudinally curved element, preferably a wire which is relatively inflexible longitudinally and relatively flexible transversely, but restrained from vibrating transversely by energy-absorbing material engaging its sides. In accordance with another feature, the invention provides a single reproducer coupled to a plurality of styli and records for combining the reproductions from a plurality of records. Referring to the drawings. Figure 1 is a side elevation partially in section of one form of the invention as applied to a reproducer for use with a "hill and valley" type of phonographic record; Fig. 2 is a plan view of a reproducer for use with a "transversely grooved" type of record; Fig. 3 is a cross section of a reproducer in which a plurality of sound boxes are operated by a common translating member; Fig. 4 is a side elevation partially in section, of a form of the invention in which two separate records can be reproduced simultaneously through the medium of a single reproducing sound box common to the two records; Fig. 5 shows a form of tlie invention designed to telephonically reproduce the matter recorded; Fig. 6 is a rear elevation of a reproducer for use with both "hill and valley" and "transversely grooved" types of record; Fig. 7 is a detailed side elevation thereof showing the method of supporting the stylus and translating members extending from the stylus to the respective sound boxes; and Fig. 8 is a sectional view in perspective of the means used for translating movement between the stylus and the diaphragm of the sound boxes. Phonograph Doll. Samuel Haskell, Brooklyn. N. Y. Patent No. 1,451,022. This invention relates to talking dolls and in particular to a doll wherein is contained a record and its operating mechanism. An object of the invention is to provide a doll more particularly in the form of a toy which will, together with a base, embody a small phonograph upon which may be played miniature records, these records having any short selection or story thereon and which when being played will give the impression of a talking doll. Figure 1 is a side elevation of a doll and pedestal therefor partly in section and showing the position of the sound-projecting member relatively to the doll body; Fig. 2 is a front view of the deyice as illustrated in Fig. 1, the same also being in partial section; and Fig. 3 is a perspective view of the reproducing mem ber which translates the vibrating motions of the needle into sound. Amplifier for Talking Machines. Joseph F. Biggs, Richmond, Va. Patent No. 1,450,241. This invention relates to an improved amplifier for use in connection with a cabinet talking machine wherein ample space is afforded in the rear of the cabinet for housing the amplifier in such a manner that the rear wall of the amplifier assumes a position in parallelism with the back of the cabinet. It is also to be noted that the forward part of the cabinet aflfords ample space for an improved combination record rack and ejector as set forth in the co-pending application of Joseph F. Biggs, Serial Number 403,176, filed August 12, 1920. It is also the aim to provide an amplifier of relatively large proportions whereby the sound waves or vibrations are considerably amplified. Another object is to provide an amplifier which is of stream line design and connected to the tone arm downwardly from the motor board and curved in order to arch under the motor and deliver the sound into a chamber at one end of the cabinet. Still another object is to provide an amplifier of relatively large proportions and of stream line design, as shown, with an aim to not only considerably amplify the sound waves, but also to produce tones more natural. In attaining this result through extensive tests by means of the stream line design and curved formation of the amplifier it has been found necessary to retard the vibrations or sound waves on one of the curved walls of the amplifier relatively to the vibrations on an opposite curved wall. .-Vlso, in order to accomplish this result, it has been found that, by providing angular abut ments and especially terminating the shorter curved wall in a chamber or pocket, the vibrations or sound waves are retarded. Figure 1 is a vertical cross sectional view of a cabinet talking machine showing the improved amplifier as mounted therein, showing the chamber or pocket at the end of the shortcurved wall thereof. Fig. 2 is a longitudinal sectional view on the line 2 — 2 of Fig. 1, also showing the pocket or chamber at the terminus of the short-curved wall. Fig. 3 is a perspective view of the amplifier shown in Figs. 1 and 2. Fig. 4 is a longitudinal sectional view through a cabinet talking machine show-ing another form of amplifier mounted therein, wherein the short-curved wall of the amplifier terminates in an angular portion acting to retard the vibrations and render them more natural. Fig. 5 is a detail perspective view of the amplifier shown in Fig. 4. Magazine Phonograph. Louis J. Thon, Marshfield. Wis. Patent No. 1,451,282. This invention relates to improvements in magazine phonographs, and the main objects are: First, to provide an improved magazine phonograph adapted for disc records. Second, to provide an improved magazine phonograph in which the records are automatically brought to playing position. Third, to provide an improved magazine phonograph in which the rec
