YOUNGSTOWIL OHIO.
SOUND-MODIEYING DEVICE.
Specication o! lettera Patent. Y Patented J une 24, 1913.
- Application led November 20, 1812. Seri-al No. 732,572.
To all 'whom t may concern? Be it known that I, VILLIAM G. SABINE, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Sound- Modifyin Devices, of .which the following is a speci cation.
The present invention relates in general to sound reproducing machines, and more particularly to novel means for modifying the sound so as to clarify the same and mutlleor soften the harsh metallic ring which is alwaysvincdentl to such machines.
One of the objects of the invention is tlie provison of a sound modifying device which is sim le and inexpensive in its construction, and which will operate in an effective manner to modify and soften the sound of the instrument and do away with the whizzing or grating sound.
A further object ofthe ,invention is the rovisionof a. device of this character which is susceptible of being constructed in such a manner as to be'upplied in the form .of an attachment to the usual sound boxes now in common use.
W'ith theseandother objects in vie\v,.the invention consists in certain combinations and arrangements of the parts will more fully appear as Ithe description proceeds, the novel features thereof being pointed out in the appended claims.v
For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:
Figure 1 is an enlarged elevation of a conventional form of sound box of the kind usually employed 'with a disk typo of talle lng machine, the view illustrating,r the sound lbox litted with the im|n-ovod sonnd modifyingr device claimed herein. Fig. 2 is a detail perspective yicw showingr the several parts of the invention in :l separated relation.
Corresponding and like parts are referred to inthe followingI description :md indicated inv all thcview of tin-drawings bythc same refeigice characters. j
In tllegvresent instance the sound "n'iodil'ying device is shown :es constructed -in the form of an attachment so as to be applied to a sound box of the conventional construetion. The sound box itself does not constitute any part of the present invention, and may be briefly referred to :is including n casing 1 provided upon one side thereof with theV usual means for attachment to the swinging arm or other equivalent member of-a sound re reducing machine, the opposite side of t e casing being formed with an open chamber?) within which the diaphragm 2 is mounted. This dia ihrgm is held 1n ositionl between rines 4 o some soft 65 materia such as rubber which fitswithin the chamber 3, and the central portion of V'the diaphru m is connected in the usual |x"nanner-to die inwardly extended end of a 'stylus lcarrying bar 5. The opposite end 70 of ythis stylus carrying bar is rigid with a head 6 whichfxils; suitably mounted in the ordinary mnner-upon the casingl .so as to 'have the nccessryrocking or vibratory movement, und proviled with the usual socket to receive thefstyluspoint.
The sound modiffying attachment vcomprises aplurnlity o 'disks.78,\ 9,'and 1 0, which are4 of severalrditferent materials assembled in face to face relation and held 80 clamped together as a unit at .one side of and against the diaphragm 2.
Referring to the materials from which the disks are made, and the individuel Afunc` t'v lis-f each, it will be observed ,that the 85 (5;7 and 1() are made of thin sheet rubare provided with the central sound igs 7 and 102L respectively. 'lf he disk 8 is made of parcl'iment and diti'ers from the otlicr disks only i'n the particular of its 9o central opening 8 boing of much greater diameter than any of the openings in said other disks. The disk t) is made of metal andits diametervis less than that ofuny of the other disks. lion/ever, the vnuid disk 9 is provided with :l central opening 9"v whose diameter .substantially corresponds to that of the openings i and l0 in their rc spoctivo disks.
ln :usomliling the attachment ulm-vfdclou scribed the rubber disk 7 is placed next to the diaphragm 2 und 'lure to tzu-c thon-with` so that. the opening "1 is opposite the june?- tion of the stylus lmr .5 with the diaphragm 2. Next to this thin rubin-r disk is placed the parchment disk or ringr H. which by renson of'ils enlarged central opening' p|-orides within such openingV :in auxiliary sound clarifying chamber l1, one side of which is formed by the disk 7, and the other side i 'of which is formed by the metal disk 9 which comes next in orderv after the parch nient has been placed in osition. The metal disk preserves the distinctness of the sound waves.` while'fthe parchment 'andrubber packing 'so'niodifies the sound as to eliminate the Whizzing orlgrating sound incident to the travel of the needle over the record and -the reproduction of the selec,- tionl )The assembling of the device is completed by placing the rubber disk l10, which is a .duplicate of the disk 7, next to the metal disk 9, so that it is l,concentric with the lother disks, and so that the opening 10a is opposite the junction of the stylus bar with the diaphragm similar to the o ening 7a in the disk 7'. kIt may ialso Abe 'o served that by reasoii'of the metal disk-9 bein aineterthan the chamber 3 within which itiis located, the: edges lof said disk are spaced. from and out -of- Contact "with the inefallie Wall ofv the said chamber 3, thus permitting the `said-metal disk to have its independent vibrationas it mayv be influenced' by the .vibrations o'fthei'main dia-f pliragm communicated -tlirough vthe first rubberf diskf? aiid the intervening parchment sheet 8. This construction and' arrangement of parts jhas' been found to be 'very sensitive andreliable in its 'action to modify *and soften the'liaish grating sound i` and metallic' ring which usuallyA accompanies Athe operation of the ordinary'gramophone.
In those forms of sound boxes where thev i diapliragn'i is made of metal, such as aliiinil' nuin',"satisfactory results may be secured in` the present invention, by omitting the metal disk and simplyutilizing the two rubber disks with 'the parchment diskv between ivliiiclithe common mica orlequivalent diaphragni'fis employed, the particular arrfingernent,l of disks herein described is the Vone preferred and ordinarily feiiiployed.
g. of less di'- .A Y, although'it `will be understood that .tliY 'e conventional form of sound box within I claim: l
1. A Amodifying attachment, for sound boxes, comprising, in combination with the main diaphragm, a laminated mufliing unit clamped within the sound Abox at the inner .side of the diaphragm and .including a pair ;cated between the rubberdisks arid'of less external diameter1 thantljie saine,\and Aa parchment disk interposed between the metal disk and one rubberdisk vand having a nu internal chamber. A modifying attachment for; sound boxes, comprising inY coinbinationwitli the main diaphragm, ajlaininatedminding unit clamped within' the` sound ybox at :the .inner side of the '.diaphraginand including-a; pair of rubber disks o'iE uniform-diameter and having central openings therein, one of the lrubber disks heling arranged=1against the diaphragm, a :metal disk arranged against one of the` rubber disksiand of .less external diameter than the same, and also ytia-ving central opening, and apareliineiit .disk of substantially the external diaiiiettv of the auxiliary sound clarifying rubber-disks and having a conei'itric hole of greater .diameter than thoselofthe other disks, said parchment disk being interposed between the metal disk and tlieother iiibber disk. 71,; v
