UNITED STATES" PATENT curios.
WILLIAM N. HUNTER, OF'BLANCHESTER, OHIO,
SOUND-REPRODUCER FOR TALKING-MACHINES, TELEPHONES,
To all whom it may concern:
Be it known that I, WILLIAM N. HUNTER, a citizen of the United States, residing at Blanchester, in the county of Clinton and State of Ohio, have invented certain new and useful Improvements in Sound-Reproducers for Talkingdllachines, Telephones, &o\; and I do hereby declare the following to be a full, clear, and exact description of such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates-to new and useful improvements in sound reproducers for talking machines, telephones, etc., and is more particularly an improvement over my former Patent #875,352, issued December 31, 1907 and my object is to provide means in connection with a sound receiving cham her for suppressing or eliminating .all.
sounds other than the pure and finer tones produced by the diaphragm.
A further objectisto provide means for intensifying the tone sound without aflecting the quality of the tone.
A further object is to provide adjustable means for increasing or decreasing the intensity of the sound.
A further object is to provide means for preventing outside disturbances or noises from reachingthe diaphragm, when the diaphragm is in use for reproducing purprovide means for adjusting the tension on the sound excluding or arresting mechanism Other objects and advantages will be hereinafter referred to and more-particle larly pointed out in the specification hereunto annexed. I
In .the accompanying drawings which are made a part of this application, Figure -1 is a vertical central sectional view through the device removed from the diaphragm. Fig. 2 is a bottom plan view thereof. Fig. 3 is a sectional'view Fig. 4 is a sectional view similar to Fig. 1, showing a slightly modified'form of device, and, Fig. 5 is a detail sectional view of a disk used in connection with the device shown in Fig. 4.
Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a cap, which is constructed in the usual or any preferred manner, the flange 2 thereon being adapted to receive Specification of ietters Patent. Application filed June 16, 1910.
the usual or any preferred form of trally through the as seen on line 3-3 Fig. 1..
Patented Jan. 23, 1912. Serial No. 567,280.
diaphragm (not shown) and in the under face of the cap "1' is formed a cavity 3, which cavity is. preferably dome-shaped and is adapted to gather the sound produced by the needle of the diaphragm. It is customaryin devices of this class to place the cap immediately back of the diaphragm and convey the, sounds through a central opening in the cap and directly into a horn or other device, but when so doing, the me chanical sounds of the machineare-fully reproduced and rendered audible, thus destroying the finer tones or sounds. To overcome the ob ectionable feature, I provide means for eliminating all tones save I the finer sound vibrations by' introducing cencap 1, a tube or similar end of which is extended to a point adjacent the device-41, the inner through the cap diaphragm, when nected with the diaphragm. The inner end of the tube is closed and in order to admit the sound waves into the tube, that portion" of the wall of the tube projecting through the cap is provided with openings 5, preferably four in number, but if preferred, a greater or less number of the openings may be provided or an elongated slot substituted for the openings. The opposite end of the tube 4 is extended a distance from the cap and is left open, so that the sound waves may escape therefrom and in order to increase the volume of'the tone, a hell 6 is introduced over the tube 4:, so as to carry the sound waves back to a point adjacentthe cap is properly con the cap 1, before they are released into thep horn or other device for recei vingthe samei The tube 4 and bell-v6 are "preferably tapered outwardly from their closed ends, so
that the sound vibrations will more readily pass through the same and as the closed end of the bell is opposed to the open end of the tube, the flares of the tube andbell will be in opposition to each other. In order to regulate-the volume of sound through the tube and bell, said bell is adjustably mounted with respect tothe tube by extending a spider 7 across the open end of the tube and extendingupwardly from the center thereof is a stud 8, which is exteriorly threaded and around said stud is introduced a sleeve 9, which is interi'orly and ex .teriorly threaded, the interior threads engaging the threads of the stud, while the ex terior threads are engaged by a nut 10, and
by means of which the bell is locked in engagement with the sleeve. The lower'end of the sleeve is provided with a peripheral flange 11, upon which the bell rests,sa1d flange fitting within the bell, while the nut is placed on the opposite, side of the bell,
thereby locking the closed end of the bell between the flange and nut, when the nut is turned home on the sleeve. hen increasing the volume of sound, the sleeve 9 is turned outwardly on the stud S and v1ce versa when the volume of sound is reduced, :1 locking nut 12 being introduced on to the free end of the stud, so that when the locking nut is turned against the e d of the sleeve, said sleeve will be held in its ad justed position on the stud.
The cap 1 has attached thereto an elongated band 13, which is preferably formed integral with the cap, although the same may be formed separable, if desired. This band is arranged to receive the end of the usual form of horn or other device and is preferably flared from its inner to its outer end and as communication with the outside atmosphere is completely closed at the point of intersection of the band with the cap, the sound produced by the diaphragm will be greatly intensified when it reaches the horn.
In practice, it has been found that the finer tones are produced at a point farthest from the center of the diaphragm and in 'order to eliminate the harsh sounds produced by the needle at the center df the diaphragm, the closed end of the tube 4 is provided'with a recess 14 and as said recess is immediately ,above the needle, the usual diaphragm and maintain a uniform vibration thereof. I l
7 As best shown in Fig. 4:, I have also provided aslightly modified form of device which consists of extending a wire 15 lengthwise of the tube 4, the lower end of the wire being attached to a disk 16, the
What I claim is 1. In a sound reproducer, the combination witha cap, of a hollow member having one of its ends extended through the cap, said end being closed and the-opposite end open, an additional hollow member. extending over the first hollow member, means to adjust the second hollow member, the first hollow member having openings therein to admit sound from the cap and the closed end of said first hollow member having a recess therein.
2. In a sound reproducer, the combination with a cap, of a'hollow member projecting through said cap, one end of the hollow member being'closed and a stud at the opposite end thereof, a wire extendin through the hollow member and stud, dis rs for securing the ends of said Wire in said hollo'w member, and means at the end-of the stud .to increase or decrease the tension; fthe 3.
