LOUIS P. VALIQUE'I, OF NEW YORK, 1\T.'Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO VICTOR TALKING MACHINE COMPANY, A CORPORATION OF NEW JERSEY.
SOUND-BOX FOR TALKING-MACHINES.
Specification of Letters Patent.
Patented Jan. 25, 1910.
Application filed October 28, 1903, Serial No. 178,933. Renewed November 5, 1909. Serial No. 526,471.
To all whom it may concern:
Be it known that I, LOUIS P. VALIQUET, a resident of the city of New York, State of New York, have invented certain new and useful Improvements in Sound-Boxes for vention,Figure 1, is a central longitudinal section of a sound-box constructed in accordance with my invention. Fig. 2, is a cross-section of the diaphragm; Fig. 3, is a face view thereof;Fig. 4, is a front elevation of the sound-box with the cover and stylus-holding arm removed and with the diaphragm partially broken away; Fig. 5,
v is a front elevation of the sound-box with 25 the cover stylus-holding bar and diaphragm removed; Fig. 6, is a face View of a ring for supporting the diaphragm; Fig. 7 is a cross-section thereof; Fig. 8, is a crosssection of a portion of the diaphragm and a flexible. ring for supporting the same; Fig. 9, is a cross section of a portion of the sound box with the diaphragm support shown in Fig.8 applied thereto; Fig. 10,
is across sectionof a portion of the diaphragm and a flexible spring ring for supporting the same and showing another construction embodying my invention; and Fig. 11, is a View, partially in elevation and in section, illustrating an adjustable rocking support for the stylus-holder, being an enlarged view of certain parts shown in Fig. 1.
Referring to these drawings, the body 1 ofjthe sound-box is recessed, as shown at 2, to form a diaphragm chamber, and is provided with a tube 3, extending rearwardly fonconnection with the usual trumpet or horn.
Alcover 6 is removably secured to the front of the sound-box, conveniently by screws 7, and serves as a retainer for the diaphragm are held in the construction illustrated, this support comprises a ring 10 contacting with the edge portion of the rear face of the diaphragm and yieldingly supported by a plurality of springs 11, mounted in recesses 12 in the rear of the diaphragm chamber, as shown in Fig. 1. The said ring 10 is situated opposite the bead 9, and the side faces of the between this bead 9 and the ring 10. j I
As shown in Figs. 2 and 3, I prefer to employ an insulating annulus 13, which is interposed between the diaphragm and the head 9 and ring 10 between which the diaphragm is held, said annulus being of nonsonorous material, such, for example, as felt fiber, and is preferably applied to one or both of the opposing faces in the form of an adhering coating. I
As shown in Figs. 1 and 7, the ring 10 may be provided with an insulating coating or annulus 1 1 on the face thereof contacting with the diaphragm. In this way the diaphragm is flexibly supported so that it is extremely sensitive and reproduces with a high degree of efliciency the vibrations of the stylus which are conveyed thereto by the stylus holder 15.
The stylus holder 15 is approximately L- shaped, as shown in Fig. 1, the upright arm 16 thereof being provided with a socket for the stylus 17, and with the usual means for holding the same in place. The upper end of the arm 16 is curved and projects through a central opening in the cover 6 toward the diaphragm, to which it is attached in any well-known manner.
The stylus holder 15 is movably mounted upon the sound-box cover, being fulcrumed preferably by means of twin points or studs 18, projecting rearwardly from the arm 16,
and seated in depressions 19 in the cover 6,
located over a socket 21 in the lower portion of the body of the sound-box, and the horizontal arm 22 of the stylus holder'projects through said opening 21 into said socket.
For the purpose of holding the stylus holder in engagement with the diaphragm in a sensitive manner and under tension, and also for varying the tension or pressure upon the diaphragm, I employ a spring 23 that encircles the arm 22, and in Figs. 1 and 11,
is situated between a cam 24 resting against the rear face of the cover 6 at the front of the socket 21, and an adjustable nut 25 having screw threaded engagement with the rear end of the arm 22, said spring being coneshaped with its base resting against the cam 24. The nut 25 may be constructed to be turned by a suitable tool, or it may be milled, and obviously can be employed to adjust the tension of the spring 23 so as to vary the pressure, with which the stylus-holder arm 16 engages the diaphragm. The cam 24:, referred to, is provided with a handle 26 by which it may be turned and its inclined face, upon which the base of the spring 23 bears, serves also to adjust the tension of the spring independently of the adjustment attained by the nut 25.
The spring ring shown in Fig. 1 exerts a uniform pressure upon the diaphragm throughout its circumference, but upon one side only, and in Figs. 8, 9 and 10, I have shown a construction for exerting a uniform and yielding pressure upon both sides of the diaphragm around its peripheral portion within and adjacent to its circumferential edge or wall of a flexible spring ring with a recess throughout its inner circumference to provide a seat for the peripheral portion above referred to of the diaphragm. In Figs. 8 and 9, this flexible spring ring 27 is in the form of a tube slit throughout its inner circumference, as shown at 28, with the peripheral portion of the diaphragm 8 seated within the slit portion, while the slit portion of the ring 27 engages both faces of the diaphragm. In Fig. 9, a diaphragm so supported is shown in position within the soundbox, the ring 27 lying within the diaphragm chamber 2, and held in place by the cover 6, which engages the front side of the ring so that the latter is held between the cover 6 find the rear wall of the diaphragm cham- In Fig. 10, another form of spring ring 29 is shown, which consists of a double walled tube separated throughout its inner circum ference with the walls joined at the sepa rated portion, as shown at 30, and with the diaphragm 8 engaged on both faces by the portion of the tube joining the walls, as shown at 30.
It is obvious that various changes might be made in the details of the constructions shown, without departing from the spirit of this invention or the scope of the appended claims.
Having, therefore, described my invention, what I claim as new, and desire to protect by Letters Patent, is
