THE TALKING MACHINE WORLD. 61 LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS (Specially prepared for The Talking ilacliine Wdilil.j Washington, D. C, Jan. 6, 1908. Talking Machine. Horace Sheble, Philadelphia, Pa., assignor to the Hawthorne & Sheble Mfg. Co., same place. Patent No. 872,586. This invention concerns talking machines and relates, more particularly, to the construction o£ the sound-conveying and amplifying tube or horn. The object of the invention is to provide an improved construction of such sound-conveying tube, the use of which results in a more faithful reproduction of the sound recorded. In the talking machines heretofore constructed it has been common to provide a sound-conveying tube tapering from end to end, the small end thereof supporting the sound box, and the inventor has found that greater fidelity of sound reproduction can be obtained by so constructing the sound-con'^■^ veying tuibe that the interior thereof near the end to which the sound box is affixed consists of a plurality of sections of prog r e s s i V ely increasing crosssectional area. The smallest of these sections c o m m u n ic ates with the chamber directly in r e a r of the diaphragm of the sound box and is considerably smaller in cross-section than that chamber. This section is of comparatively short length, as are the succeeding ones, except the last, which may be of any desired length, and a tapering amplifying horn is connected to the end of this section. If desired, the sectional tube and horn may be coupled together in a manner permitting relative movement, the sectional tube, in this case, corresponding to the tone-arms now in general use. Preferably the tube and horn are circular in cross-section, the sections of the tube being cylinders of small length, except the last, whose length is determined by the length desired for the complete tone-arm. The sections of the tonearm are so constructed and assembled that the end of each extends a short distance into the end of the next larger section, so that a series of air chambers or pockets are provided about the ends of the sections. By reason of this construction, the diaphragm of the sound box can vibrate more freely as the air pressure thereon is, under certain circumstances, considerably reduced. The preferred embodiment of the invention is illustrated in the accompanying drawings, in which Fig. 1 is an elevation of a portion of a talking machine broken away and sectioned in part; Fig. 2 is a longitudinal section of a tonearm on line 2 — 2 of Fig. 3;and Fig. 3 is a transverse section on line 3 — 3 of Fig. 2. Talking Machine. Henry B. Babson and Andrew Haug, New York, N. Y., assignors to Universal Talking Machine Co., Newark, N. J. Patent No. 872,783. This invention relates generally to talking machines and more particularly to supporting means for mounting the reproducer in operative relation to the horn. In certain types of machines of this class now in general use, provision is made. for supporting the horn and reproducer independently of each other, the arrangement being such as to permit the horn to be swung around into any desired position while the reproducer is either in or out of operation, without disturbing the same, and at the same time to permit free movement of the reproducer without such motion being transmitted to the born. While such an arrangement affords many obvious advantages and has received general approval, objection is made to the particular forms of mechanism heretofore employed, owing to the large number of parts, the care and accuracy required in fitting and assembling the parts to insure proper co-operation and the general com plication involved in the construction which renders it expensive, difficult to adjust and altogether unsatisfactory from the point of view of both the manufacturer and user. The present invention is designed to obviate the objectionable features above pointed out in the production of a reproducer supporting arm and mounting therefor employing a minimum n u m ber of parts of a form suitable for being manufactured at a comp a ra t i V ely low cost, readily assembled or disconnected, and so arranged as to coact efficiently in permitting free movement of the reproducer and its ready adjustment in or out of operative relation to the sound record. The accompanying drawings will serve to illustrate a device suitable for carrying the invention into effect. Fig. 1 is a view in side elevation of a support for a sound reproducer, constructed in accordance with the invention, the same being shown applied to a well known type of talking machine. Fig. 2 is a rear view thereof. Fig. 3 is a vertical section on the line s', s^ of Fig. 1. Fig. 4 is a similar view taken on the line, s*, s\ of Fig. 3. Reproducing Horn for Talking Machines. William E. Leighton, Pembroke, Me. Patent No. 872,828. This invention relates to the horns used on the reproducers of talking machines and has for its principal object the improvement of the horn to the end that the tones reproduced are prolonged and made more clear. This i s accomplished b y attaching a number o f the strings to the horn which are tuned to the chromatic scale so that when a tone is made by the ^ talking machine record the string tuned to that tone vibrates in sympathy and also the strings tuned to the harmonics of the tone. Fig. 1 is a perspective view of a conventional talking machine with the improved horn secured thereto; Fig. 2, a central longitudinal sectional view looking at one side of the inner surface of the horn; Fig. 3, a cross-sectional view, and Fig. 4, a detail showing one of the keys and its mountings. Tone Purifier. Adalbert T. E. Wangemann, West Orange, N. J., assignor to New Jersey Patent Co., same place. Patent No. 872,592. This invention relates to devices for purifying or improving the quality of tones produced by an instrument such as an Edison phonograph or other talking machine, and may be used also WILKESLYKE Automatic Start and Stop ATTACHMENT This scientific attachment is made to fit the famous Edison Standard, Home and Triumph Phonographs. It automatically starts the machine on clos= ing the gate and stops at the end of record, thus enabling the operator to wait on customers or perform other duties.
