rin, a citizen of 'the Unitedta Specification of Klettern latent.
.lo all whom t may concern:
Be it known that l, Rigi-nenn dnt/ine residing ik, l n au Jamaica, 1n the county `oi..FLueene end State of New Yorln havelinvented certain new and useful llnproveinents in Sound Boites7 of which the following is`a speciiication.
My invention relates to improvements in soundboxes, the lfeatures end advantages of which will be apparent to those skilled in the art from an understanding ot the following description in connection with the drawings.
ln the latter, Figure 1 is a face VView et" the sound-box with a portion broken away; Fig. 2 is a section partly in elevation on the line 2-2 in Fig. 1 looking in thedirection of the arrows; Fig. 3 is an enlarged detail of Fig. 2' Fig. e is a section partly in plan through the line itt in Fig, and Fig. .5 is anlenlarged View of the back el the stylus arm. l
Describing now the devices of the drew ings, 1 is the back 4of the sound-bon secured by screws 2 to the ring having an inwardly directed front flange li. 5 is the diaphragm mounted in the space between the bach l and flange 4 between the usual rubber gaskets 6.
The neck of the sound-bon: consists ot a sleeve 7 having a ange 8 secured by slioula der-screws 9 to the hack 1 with a rubber washer l0 between them. The bach'plate has a central opening through it continuous with'the sleeve 7.
The sound-box is attacl'iahle to the tone- -arm as follows, the end o2 the latter being which is notched to receive the pin 13 asv shown in Fig. 2, whereupon the thumbnut may be tightened to secure the soundbox rigidly to the tone-arm. rl`hen0teh or slot is, of course. so located as to give the soundbox the desired operative position for en ample with the stylus bar inclined indi cated in Fig. 1. "l 4 ln Fig. 2, l show a further means for deM tachably connecting the sound-box to the tone-arm -Without objectionable looseness or rattle which may he used either independently of or in conjunction with the described thumb-nut 14. rthis consists of a circumterentially-disposed laat-spring l5 bent to Application :flied lennary mi, Sei-icl o. 11,4%,
contorni closely "to the internal circuler cross-section et the neclt 7. i rivet 16 through one end of the spring and the wall oit the neel: secures the spring in its described position-within the. neclr. The other end oit the spring is :tree` and has a stud 1'( project-- ing through hole in the neclt 7 to bear against the interior oif the tone-erin 1'2. ln. this way the outside surface cit' the neck is brought into iirrn, holding, non-rattling con tact with the interior ot' the tone-erin.
18fis the stylus-bar pivoted intermediate .its length on the pointed pins 19 projecting from the ring At this place, the stylus bar has a cross' iece 18a formed with sockets 20 against the' iottoins or which the pivotm pins bear as indicated in Figs. 3 and ll. The upper erin of the stylus bar has a toot le@ by which it is secured to the center ot the diaphragm end its lower erin has the usual stylus or needle receiving socltet 18 with ce operating set-screw 18d.
The stylus-bar is operatively held on the points oit the pivotl pins -19 by means as tol:
lows: 21 is a screw tapped into the ring o ot the sound-bon and intermediately entendtill ing without Contact (see Fig. il) 'through a considerably larger hole 22, (compare Fig.
' 5) in the crosspiece 18 of the stylus-ber on a. line with the sdcltets 20. 23 is a flat or leal-spring bent in the form ot a how haw ing a central hole through which the shanlt of the screw Q1 passes. he bent-bach ends of this spring bearon the cross-piece 18a and force its sockets 20 into contact with the points of the pivot-pins 19 with a spring pressure depending on the edjustinent oi? the screw 2l? whose head, it Will be noted? beers against the middle portion oi3 the sprin'. Finally it will be noted that the top portions 18E ot the cross-piece 18a over the pivt-pins are transversely rounded. (See Fig.. 3 and compare lllg". l.) The spring 23 bears on these transversely round top portions, their curvaturc'having a greater .t
radius 'than the shortest distance between said top-portiens and their respective pivot points.
lllhat l claini is 1. ln combination, a. tone-erin, a soundbox, and connecting means between thorn comprising a tubular neck on the sounddiort telescopingl with the tone-erin, and a 'leeft spring attached to the interior or the inner telescoping parti, tree @porties et said titi l. 'Il ti spring having a lateral projection which eX- lendg outwardly though an opening pro vided for it in said inner telescoping;l part into Contact with the inner surface of the louter telescoping part.
2. Tn combination, :i tone arm; a, Sound box; und connections between them eo1nprising :i tubular neck on the sound box telescopingwith the tone arm.v and n leaf spring disposed circumferentially within the inner telescoping` part und bent to conform to the curvature thereof, so as to lit closely against the inner surface of said part, the free portion of said spring having a lateral projection which extends outwardly through an opening provided for it in said inner part into direct Contact with the inner sur face of the outer telescoping part.
3. In combination, a tone arm; e Sound box; und connections between thezn coniprisingn tubular neck on the sound box telescoping with the tone arm, a pin-and-slot connection.
meme?" between saidneek and said tone arm for eccurately locating the sound box with rele,- tion to the tone arin and to hold it against 2 rotation, and spring means Within the interior of th inner telescoping part located opposite said locating means and extending; through in openi; provided for it in the said inner telescoping part into direct eoni0 tact with the inner surlace of the outer tele I scoping` part, thereby to positively secure said neck and tone arm together in such telescoped and located relation, so as to prevent rattling' of the sound box.
In testimony whereof, I have signed my naine to this'speciiiczition in the presence of two subscribing witnesses7 this 25th dey of January, 1915.
