fo all whom it may conserva: Y
it known that l, WILLIAM ALBERT (lineman, citizen of thevUnite'd, States, in the County of Lawrence and State ofirkansas` have incan swing transversely ot the plane of the diaphragm, and wl'ierehy the diret-tion ot' pressure upon the har, dne to the weight ot the box and the drag of the needle upon the reeord, is snirstantiali' is in the inriintah oixierative position, preterahly at an angie ot' l5@ with the horizontal.
yThe invention also includes means for rennrvahly attarhing the needle point to the stylus har and 'Forinoi'inting the diaphragm in the easing. i
in ohjert of the invention is to provide a simple. inexpensire and etlieient sound hox 't'or ieprraluring or recording the sounds hy meansy ot rwrord. employed in phouographs, talkingr niaehines and similar apparatns hy ineans ot' which the sounds can he reprodrifted with rlearnesss and (listini-toilets.:and

has a reeess Another object of the invention is to provide a sound box in whieh the stylus har is' mounted to roel( freely transversely of the plane of the diapl'n'aain. on .eonieal fnlerinn points located in the line of the resistanee to motion due to the wei` on the point otl the needle` and the dragging;r of the needle on the reeorih and whieh is provided with auxiliary supportaI -in the -forni ot' hallfs' or rollers resiliently held in ght ot' the hox restingy 70 are on enffae'inff seats n'ovided therefor 75 h n n near the ends of laterally. extended portion` oi the etylnshar, whereby is afforded a aryingr eontaf'tor irir'tional engagement as tht` har rochaI under the impulser: eonnnnniealed thereto hy the needle in traversingthe sound Arooyw of the reeord, in eonsernlenre ot' which the resilient positioning ot' the styliny har 'autoniatiealiy adjuntav itseliE to the varying` positions and niorenientsot' the parts.
The invention ronaists in the eonsiruetion and eonihination ot parts'to he more fully deserihed hereinafter and partirularly set t'orth in the rianne.
i views, and in whieh- 50 with ref-:peet to the horm'niiai. in whiri:
le'i'ore noeeedino' to a more detailed dei srription ot niy invention. it yuhould he I the. points 31 are "so formed that tensions are outwardly l, quently, what' ,fthe sound box is At. each side of the arm the yolre has a taered recess or .seat 29, whichvreceives a fulbiiim point 31 carried by an extension 30 rigid with thecasing ot' the box.. lhe exand laterally disposed as is shown mpst clearly in lfig. 1, and they ext/end at angles of -subs'tfmtially 45 with a line drawn from a point intermediate the points 31 to the center of the casing; that is, at angles of 45 with the length ot the stylus bar. The tapered recesses Q9 are simi larly inclined aty angles 'of 45. Consearranged 1n its operatitQe'posit-ion, which, too, is at an angle of prcfieiiably'lo with the horizontal, the pressure of the yoke against the iiulcrum points is upward; that is, in a substantially vertical direction, owing to the inclination of the fulcrum points and the seats therefor with respect to the length of the stylus bar. It will of course, be understood that the angie of inclination and the angles which the l fulcruin points make with the iengthot the erswith the stylus bar is 'and downwardly disposed.
stylus barneed notbe exactly't'g, and these angles may be between 4G and 500 with substantial'ly no diti'ere'nce in the operation and efficiency of .the device. Hereattcr, where I refer to this angle asbeing,- 45o it will be understood-that this value isapproximate,
land may be varied somewhat with special conditions and-under dliicrent. crrciunstances.
The yoke 25 may be curved, for example .as shown in the drawings, to render it artistic in appearance and at the same time to provide end "tages 32, wiich are outwardly` he end. iaccs have recesses forming seats land adapted desired, they to receive spherical rollers/orbearing balls 34. Substantially Qa-shaped"resilient members or springs are 4secured upon the sound box casing at opposite sides of the s tyhis bar and may be mounted in place by any suitable means, for example, by the use of screws 36. fit the free ends, the keepers are enlarged to terminate inv sockets 37 having recesses 38 which the balls 34. The springs thus serve to hold the stylus bar in piace andto maintain the yoke in suitable movable engagement with thefulcrum points 31, to permit the i to rock or oscillate freely, transversely o inc plane of the diaphragm.' lThe. sprii owing to their form', cause an inward and upward pressurezior maintalninuj the stylus bar operatively on position against points.' The engagement of 'tulcruin the spring lreepa movable one, the ball and socket parts to adjust themto variations fn pres The engages f ent engenand thus does not tend to owingto the provision of joints, and allows the selves automatically sure andA position. ders little friction interfere with the freedom ot' movement of the 'stylusrban The balls 34 may be fashioned from any suitable material preferably from glass or the like, though ot course may consist of steel balls.' ulcrum points 31 may be of hardened steel butare preferably of some noirmetallic substance such as agate or quartz. The back plate 20 is preferably t0o,`o a non-metallicl substance and is cemented in position; The recesses 29 may be lined with a suitable nonmetallic substance similar to that formingthe fulcrum points 31. The springs owing to their S-shape cause an inward and upward pressure.
rlhe barrel has a longitudinal 'recess 31) therein and which is formed to receive the reproducing' points or needles 4() cording` tool. The barrel has a second `opening therethrough and arranged transverse ot the recess 89, and intersectingr the same. A locking bolt or member '42.is movably arranged in the opening 41 and has a .threaded end 43 upon which is mounted a thumbq nut 44. The opposite end ot the member 42 projects from the barrel and has an opening 45, in to which extends the end of a curved spring' 46, the latter being sccured in place upon the yoke by means ot' a screw 47 or in any other convenient manner. The member 42 has a notch 48 adapted to engage the shank of the needle to jam the same against the side of the 'recess 39 when the bolt is suitably positioned for this purpose by means ot the jam nut 44. The cylindrical form of the nut permits the spring 46 to move the member 42 across the recess 39 so that the needle point can be easilywithdrawn. A partial turn of the thumb-nut which draws the member 42 along the opening 41 against the tension of the spring- 46, instantly clamps in place in 'the barrel, a needle point, vwhich engages the notch 48. i
Having' thus described my invention, l claim new, and desire to secure by Letters Patent:
1. In a sound box, a diaphragm, a'stylus bar controlling said diaphragn'i and havingr a yoke at substantially right angles thereto. and a ulcrum engaging said yoke, whereby said bar is mounted to swing transversely of the plane of said diaphragm, said fulcrum being at an acute angle with the direction of the length o-t said bar, said bar lyingr in a plane substantially parallel to that of said diaphragm.
