The talking machine world (Jan-Dec 1908)

THE TALKING MACHINE WORLD. 63 type in which sound waves are recorded on a disc or cylinder record and sought to be reproduced therefrom by a diaphragm vibrated by a relatively traversing stylus and record, of a contiguously-mounted resonance chamber, at least one wall of which is a sounding board, into the interior of which chamber the sound Waves produced by the diaphragm of the reproducer are discharged; and means such as a pivotallymounted hollow sound-conveying arm on the free end of which the sound reproducer of the ^ ^ talk ing machine is mounted, the other and pivotally-supported end of said arm being mounted in an apertured wall of said resonance chamber in such manner as to discharge the sound waves thereinto. Also in deflecting partition walls in the resonance chamber, operating primarily as an amplifying conduit for the sound waves on their passage through the resonance chamber and during their impingement against the inner face of the sounding board, and secondarily to modify their tone by contact of such partition walls with the resonant fibers of the sounding board. Also in the provision of valve mechanism governing the inlet to the resonance chamber, as also valve mechanism governing its discharge ports, whereby the tune production may be regulated, namely, producing either loud or soft tones, with diminuendo or crescendo, at the will of the operator and wliile the Mg3 machine is in operation. Also in other detail features of construction and arrangement of the elements relatively to the cabinet, in each of the two alternate forms thereof hereinafter described; the combined elements being well adapted to be contained in a cabinet and constitute a compact, self-contained and readily transportaJble machine or instrument. The basic principle of the invention is exemplified in a device wherein sound waves are reproduced from a "record" thereof by a contacting stylus vibrating a diaphragm and discharging the sound waves so produced into the interior of a resonance chamber of the character recited, whereby they operate to sympathetically vibrate the sounding board wall or walls thereof; while a further basic principle is the deflection modification and amplification of such sound waves within the resonance chamber, exemplified by the provision of outwardly-diverging partition walls interiorly disposed between the sounding board wall or walls of such resonance chamber. In the accompanying drawings illustrating this invention in two of its best forms, Fig. 1 is a vertical section, partly in elevation, wherein the interior of the cabinet is reached through a hinged closure in one of its side walls, and wherein the resonance box is placed over the open top of the cabinet, the back of the former constituting the top of the latter and not necessarily having any function as a sounding board. Fig. 2 is a section of the resonance box, drawn on the line 2 — 2 of Fig. 1. Fig. 3 is an elevation of the pivoted sound-conveying arm constructed to operate with the form of device shown in Fig. 1. Figs. 4, 5 and 6 are elevations in perspective of the elements comprising the soundconveying arm of Fig. 3. Pig. 7 is an elevation in ■ perspective of another form of the device, wherein the top of the cabinet is provided with a hinged lid or door and the resonance box mounted on the inner face of the door, in such manner that both tlie top and back sides of the resonance chamber may operate as sounding boards; and Fig. 8 is a horizontal sectional view thereof, through the center of the resonance chamber. Fig. 9 is an elevation of a form of the pivotally-mounted sound-conveying arm constructed to operate with the form of device shown in Fig 7; and Figs. 10 to 13, inclusive, are elevations in perspective of the elements comprising the sound-conveying arm of Fig. 9. Pitch-Indicating Device for Ghai'hophones AND THE Like. Theodor Zoebl, Chicago, 111. Patent No. 872,399. This invention relates to improvements in pitch-indicating devices for graphophones and the like, and the object of this invention is to provide a pitch-indicating device by means of which the speed of the record may be regulated to produce any desired pitch in the reproduction o f sounds, and in which it will only be necessary to primarily adjust the device to a given tone, as for instance, middle C, and from that tone as a starting point the speed of the record may be adjusted to give any desired pitch. In the drawings. Fig. 1 is a view, partly in section and partly in elevation, of a speed governor of a graphophone, and having a pitchindicating device, embodying the invention, attached thereto. Fig. 2 is a front elevation of the locking collar. Fig. 3 is an outer face view of the pointer. Fig. 4 is a side elevation thereof. Fig. 5 is a front view of the scale disc, and Fig. 6 is a perspective view of a graphophone provided with a device embodying the invention. Phonograph. Charles Thoma, Jr., and "Walter Thoma, Carlstadt, N. J. Patent No. 873,969. The present invention relates to phonographs or other sound-reproducing machines, and has more particularly reference to a multi-record or a repeater phonograph. In_ machines of this character, the record, or the sound-reproducing mechanism, is given a reciprocating motion, one with relation to the other. One motor being utilized to effect the forward feed or outward excursion during the sound-reproducing period, and another motor, generally a spring or a weight, is utilized to return the parts to their original position at a greater speed than that _E1DI attained during the outward excursion. The chief object of the present invention is to produce a multi-record machine operating automatically. ' ' Fig. 1 is a plan view of a phonograph embodying the invention. Fig. 2 is an end elevation looking in the direction of the arrow 2 in Fig. 1, showing the stylus disengaged from the record. Fig. 3 is a vertical sectional view on the line 3 — 3 of Fig. 1 showing the stylus in engagement with the record. .Fig. 4 is a detail view of the double reversely threaded repeater screw.. Fig. 5 is a vertical sectional view on the line 5 — 5 in Fig. 1. Fig. 6 is a sectional detail view of part of the feed screw. Record Needle. Harvey H. Allison, New York, N. Y. Patent No. 874,819. This invention relates to needles used in connection with talking machines, and has for its object to provide means capable of producing even, harmonious sounds, free from the chatter, vibrations and strident tones commonly produced by the devices now in use. Fig. 1 is a perspective view showing a device embodying the invention applied to the sound MR. DEALER AILTONES All-Tones for all cylinder niacliincs.
