Specification of Letters Patent.

Application filed November 19, 1908. Serial No.4633e5.
To all whom it may concern:
Be it known that I. ALEXANDER N. PIER-' A IAN, a citizen of the United States, and a sion of; an improved mounting for the stylus lever,in order that the same may have great freedom of movement in" tracking the grooves-of the sound record, and in order that chatter of the stylus in the record groove due to inertia and'lack of balance of the-moving parts,may be obviated.
More particularly, the object of my in 5 vention is to provide 'amounting'for' the stylus, which shall permit the latter'to be usedin connection with records havin two fhun'dred threads to -the'inch,-and' tracl the sanie faithfully and without injury to the record or the stylus. V a j -"While: the stylus mounted'in thefmanner of'my invention is equally well adapted for use i'n'con'nection with records having one" hundred or some other number oft-breads per inch, the requirement" of great facility of movement of the, stylus lever, bot-11in adirection parallel -to and transverse tohthe record groove, 'is particularly i'niporta'nt'in' the case of the two hundred thread record,
or other, record having a' great number of threads per inch, owing to the thin-walls between the record grooves, which "might be broken down, or jumped'-across,rby' astylusythe parts moving with which have considerable inertia, and to the character of the record grooves generallyl Accord ingly, a stylus mounting of the least possible inertia and the greatest'possible balance is desirable. This is provided for in my invention-bymounting the-.stylus 'lever on .a' member, preferably f the floating weight, which is so shaped as to be symmetrical with respect to an axis upon it is mounted to-allow'rotation or lateral movementin a plane transverse to the record grooves, the said meniber also beinig'perlhitted to shiftnot be jarred from itsposit-ion by a blow on the phonograph-transverse to the'direction of the grooves in the sound record, whereas such a blow delivered on a machine employing the hinged floating weight,
well known in the art, would move the same 3 violently in a direction transverse to the record grooves.
Other objects of my invention are the provision of improved details of construction and combination of parts.
fln order that my invention may be more clearly understood, reference is herebymade fllO the accompanying drawings, illustrating a preferred form thereof, in which Figure l is. 'a 1 central vertical section i through a reproducer equipped with my invention, and Fig. 2 is a bottom view thereof.
2, which has formed integrally therewith ?the neck 3, to which the phonograph horn gmay be connected. The diaphragm 4 is parallel to said grooves. A weight or meinher so mounted is evenly balanced and can.
The sound box 1 is formed bythe member jclamped in place between gaskets 5 and 6,
iwhich are secured in place between the outer iperiphery of niember 2 and member 7 of ;'body. 8 of the -reproducer, said member 7 extending parallel to and a short distance below the diaphragm 4:. The body 8 is prol ivided above member 2 with an internal @screw thread to which the ring 9. formed lwith an external screw threadis adapted to ibe'fitted, this rlngbeing-screwed into place to firmly hold the body of the reprod'ucer,
the diaphragm and member 2 together. 4A short-stud 10 is mounted-as by being I screwed into a sntiall hole in body member-'2',
thisstud l0 projecting 'at right angles to member 7 below the same, forming theaxis' for cylindrical floating WQlgl'llZlLnWlllCll is formed with a central vertical'opening' 12 Iota slightly larger diameter than zthe stud 10. Floating weight llis likewise provided with a cylindrical passageway 13 parallel; to opening 12. Weighbll isiprovided on- ;its under side with a pair of earsorlugs l l l, preferably formed integral with the weighajthrough which aggtends the screw 15, 'on which is pivotally moiinted stylusflever 16 carryingstylusll. The lugsl lareprefierably so :placed that pin or screw '15 exaflange ltlfrom the bottom of which tends downwardly at one point stirrup 20.
The tioatin weight is mounted with axial passage 12 embracing stud l0, that the Weight 1]. is free to rotate about the stud, and also to move longitudimtlly of the same. The extent of both these movements is determined by the engagement of pin or screw 21, which extends from the lower periphery of the veight, with the stirrup. ihe parts are so proportioned that passage 13 through the eylindrit'ral Weight. is located directly below the center of the diaphragm When-the Weight is mounted on stud 10, passage 13 then being in line with opening 22 through body member 7 of the reproducer, thus affording a continuous passage Way for the link 18. he stylus lever 16 is mounted with its axis 15 directly below the axis of symmetry and rotation of the Weight 11. The lever arm of link 18 is preferably considcral'ily longer than that of stylus 17, so that. the movement of the stylus in the record groove may be considerably amplified in the diaphragm.
il ith this construction it is to be noted that; the floating weight slides freely on stud 10, always so moving in a plane perpendicular to the diaphragm, allowing the stylus to perfectly follow the up and down variations of the record groove. While the Weight on which the stylus is mounted being free to rotate about its axis always allows the stylus the greatest: freedom in movements transvers to the record groove in tracking the same. The construction of Weight 11. in the form shown and mounted in the manner shown. provides a ell balanced mounting for the stylus lever and by which lateral movement can be imparted to the stylus with the minimum. of resistance to such movement. The Weight as thus formed is also easily manufactured, and is so located as to take up little room and not be in the Way.
It. is understood that my invention is not limited by the precise device or construction shown, but may be varied Within the scope of the appended claims without departing from the spirit of my invention.
Having now described my invention, What I-claim and desire to secure by Letters Patent is as follows:
1.- la a phonograph reprodncer, the combination with a diaphragm, of a floating aveight mounted free to rotate around and to shift longitudinally of, an'axls, means limiting movement bf said weight to such rotation and shift a stylus lever supported ]')l\'()l21lly by said Weight, and a connection from said lever to said diaphragm, substan tially as described. k
