PHONOGRAPHIG sown-Box;
Specification of Letters Patent. Patented Sept. 29, 1914:.
llpplieation filed July 5, 1913. Serial No. 777,537. I
To all whom it may concern Be it known that I, JOHN H. VANMATER, a citizen of the-United States, residing at Atlantic Highlands, in the. county of'l /lonmouth and State of New Jersey, have invented certain new and useful Improvements in a Phonographic Sound-Box, of which the following is a description.
My invention relates to means employed for transmitting articulate and musical sound vibrations from the contact needle of a phonograph to its resonant diaphragm, and from which they are transmitted in the form of sound waves by a suitable amplifier.
'The object of my invention is to produce and preserve the vibrations peculiar to articulate speech and musical sounds, to the exclusion of those produced by the scratching or frictional effects peculiar to phonographs.
In phonographs,
heretofore part of their sound vibrations have been transmitted from the stylus point to the interior of the amplifying horn through mechanical con nections or sound conductors leading from the stylus needle to the materialforming the sound box,
thence through such'material to the interior of the horn; and such sounds so transmitted irrespective of a diaphragm or sounding board are generally of an objectionable nature.
In carrying out my invention and to avoid such objectionable sounds, all parts ofthe mechanism employed for recording and'reproducing musical and articulate sound vibrations, including the stylus and its holder are insulated from the-sound box and horn,
by means of a keeper composed of material which ofi'ers an effective resistance to the passage of all sound vibrations through it; so that the only way that such vibrations can be transmitted from the stylus to the interior of the 'horn must be through asingle transmitting member leading from the needle to a diaphragm and thence to the interior of the horn.
My invention further embraces certain forms of a sound transmittlng member leading from a stylus to a resonant diaphragm and adapted for carrying with an increasing volume and clearness certain vibrations common to musical sounds andv articulate speech which accord with certain vibrator characteristics of said ,member, and in'tran's?" mittinlg with a decreasing force and .clearthe insulator ness other sound vibrations which do not accord with the same. 4
I attain these objects by means illustrated in the accompanying drawings made a part hereof, wherein:
Figure 1, is a plan of the under face of a phonograph sound box embodying my invention; Fig. 2, is a sectional elevation of the device shown by Fig: 1; Fig. 3, shows a part of the device of Fig. 2, in section; Fig.
device of Fig. 1; Fig. 5, is a modified form of the device of Fig. 2, shown in section; Figs. 6 and 7, are modified forms of part pf the device of Fig. 1; Figs. 8 and 9, show a working form of my invention, and Figs. 10 and 11, show a practical form of mechanism.
Fig. 1, shows a plan of the shell of a sound box M, in connection with a stylus arm S, for holdin a stylus, the same being pivotally connected to an insulated inertia plate P, held within the'sound box; also a resonant diaphragm D, with a transmitting member T, leading from the stylus arm S, to the diaphragm D.
F ig. 2, is a sectional elevation of Fig. 1, showing the shell of the sound box M, rovided with a sleeve or horn attachment M. Inside of the box M, are shown two insulating rings R, and G, between which is held insulated from the shell a flexible diaphragm D, while the inertia plate or ring P, is held insulated frdm both the box M, and the diaphragm by the insulating ring G. The insulated inertia plate P, has a stylus arm'S, pivotally connected to it at S. The transmitting member T, is rigidly united at one end with the stylus arm S, while its other end is provided with a post T, which is joined to the center of the diaphragm 1); whereby the post S, is connected to the diaphragm D, by means of the member T, and its post T. S shows a stylus placed in the arm S. M is a snap'ring used for holding G, and its plate P in place. ,Fig. 3, is a reproduction of part of Fig. 2, with thestylus arm and transmitting member omitted, showing enact the lugs P, by which a stylus arm can be. connected to the insulated plate P.
Fig. 4:, shows a plan of an inertia plate P, with two lugs P, P, for pivotally holdmg a stylus arm; the outwardly extending flange'P being for the purpose of engagingthe insulating ring G, as shown in Fig. 2.
e5 4, is a plan of the under face of a part of the 7 and a fulcrum plate P, insulate member T, will not be communicated through P, owing to its weight or inertia,
vening insulating ring G.
Fig. 5 shows in section 9. dia hragm from each other but held together by the transmitting member-T, which is pivoted to 4 the plate P; all of which forms a complete mechanism which can be slipped in or out of a sound boxior held therein in; an msulated condition by means of the insulating rings G and R.- x
Fig. 6 shows analogo ly fine of the .elements'of my invention whlch relates to the peculiar construction of the-transmitting member T, and here shown as a separate article consisting of a blade T, adapted for being rigidly attached to the stvlusarm; which blade has, a post T, held to a by a spring T, which ost is connected to a resonant diaphragm the object being to show that an vibrations imparted to the blade in a direction perpendicular to the plane of the diaphragm will be transmitted 'aato it through the post T-, while any vibrations in the blade parallel to the plane of the diaphragm will simply swing relatively to the post without vibrating the diaphragm.
This same' effect is attained by means pe 40 culiar to the construction of such a transmitting member as shown by Fig, '7, consisting of a blade T, made throughout of comparatively thin material, and having part of it tapering in width andiorr' ed into a spiral T to which a resonant diaphragm D,'is directly attached; the spiral part'Tf', being formed so 'aslto be comparativelyrigid 1n the direction perpendicular to the diaphragm and comparatively flex .50 iblein 'a transverse direction whereby vibrations one way in the blade will be trans- -mitted to the diaphragm while those in another way ,will-not be transmitted; as described in connection with Fig. 6. Y
Figs. 8 and 9, graphically represent a diaphragm D, fixed in a ring D, and centrally connected at D, to the post T, of the trans: mitting member T, which forms its sole support and holds it free from contact with G0 the late or ring P and otherparts of the mec anism to which sound vibrations might be communicated.
Figs. 10 and 11, show a plan and a crossdimensions approximately e nor to the shell of box M, owing to the inter- 4 which forms a section of a practical form of mechanism adapted for carrying out my invention; in Which' the transmitting member or blade T, terminates in a spiral T with its flat parallel to that of its blade T, and provi d with a post T, for connecting it with the diaphragm D.
In this form, the diaphragm D, and fulcrum plate P, connected by a spring joint S, to the stylus arm S, are insulated from each is also insulated from the mouthpiece M, part of the horn to which it is attached; 2
Inthe construction of the transmitting *other'and from the shell M, while the shell member T, I find thatcer t'ain features are essentialfor its better performance, which are; a greater width and rigidity one way than the other as shown; a greater length than that represented by the distance from its stylusar'm to its junction with the diaphragm: hence the necessity of a spiral or analogous form to increase. its length and not its reach, and the necessity of maklng 1t tapering in its width to prevent monotone sound vibrations which-would result if its cross-sections were equal throughput its length. 3
What I claim as my, invention is:
1. In a sound recording and-reproducing machine, a stylus arm and a vibratory diaphragm united by a sound transmitting member made of thin material tapering in width and formed at its smaller end nto a spiral with its wide dimensions perpendicular 'to the .plane of'the diaphragm to which it is attached.
2. In a sound recordin and --reproduc1ng machine, a complete mec anlsm for-receiving and transmitting sound vibrations and comprising an insulated stylus arm and ful: crum, an insulated. vibratory diaphragm and asound transmitting member ,uniting the stylus arm with the diaphragm and consisting ofthin material, tapering'in width and formed at its smaller end into a spiral with its Wide dimensions perpendicular to the plane of the diaphragm to which it is attached. Y
3. In a sound recording and reproducing machine,a sound box,a vibratory diaphragm therein, a stylus arm, a transmitting member composed of tapering material and made partlyinto a spiral for connecting thediaphragm to the-arm, and a body supported'within but out of contact with said sound box for flexibly holding the stylus JQH'LVANMATEBz armin place;
