.Application filed March 5, 1925; Serial No. 13,387.-
My invention has reference, in its broad aspect, to improvements in. graphophone' needles of the type designed especially for use with disc records and more particularly it is my purpose to provide a 'graphophone needle with a point of iridium or othe metal which is'practically permanent .and. will function to greatly improve the quality of reproduction of the instrument towhich it 1 is applied; first, by effecting the elimination of so called surface noises such as scratching and the like; second, by softening and clarifying thereproduced tones and espe cially those of a high frequency or register such aslyric soprano female voices; third, by'bringing out the quality of soft toned instruments -such as harps, flutes, violins, and the like, and rendering the reproduction of selections executed upon such instruments 1 more/accurate and pleasing; and, fourth,
by effecting a more clear and accurate reproduction of vocal selections,particularly with reference to enunciation.
To the end that the above and other equally. import-ant objects and advantages ma be attained, I have formed my needle wit which is relatively insensitive to soundimpulses productive of surface noises and strays, and within this cavity I interpose loosely a pin or plunger, the insertion or removal of which respectively affects the loudness or softness of the reproduction.
The shank of my needleis formed with a bend intermediate its length from which the point extends at an angle opposed to the bend and laterally .toward the graphophone reproducer. By so directing the point a much more effective contact with arecord 9 is obtained.
The structural elements employedto accomplish the above and other results and objects, and the method followed incforming the graphophone needle and arranging the elements of the same, wil be hereinafter more fully described in details and pointed out in the claims, but thescope of my invention .may only be determined by the limits of the appended claims.
In the accompanying drawings wherein is illustrated one embodiment of my invention;-
Figure 1 is a detail view of my needle a hollow, medial or central cavity oftlhe needle, and a portion of the needle bit,
Figure 3; View A shows a "front elevatlon of'my needle, and view B a view similar to A but witl'i'the needle turned to illustrate the relative angular relat-ionship'of the parts .thereof.

I a My needle; (4) is formedwith a bend (6) intermediate its length so that the "lower "portion (7) of the needle is given a direction more nearly vertical to the record (5) than the upperportion (S) thereof WlliCh'iS retained in the bit, (2) of thereproducen- In practice the body of my needle is preferably formed by drawing out a hollow metallic wire or the like, sothat the central needle cavity (9) is gradually restricted toward the lower end of the portion (7 of the needle. record engaging iridium point (10) of a shape generally approximating the cross-sectional configuration of a record groove is afiixed to the lower end of the port-ion (7 in any suitable manner and extends at an angle reverse a the bend as gement shown clearly in Figur 4, and angularly tiallyth'e length of the portion (8) thereof is a pm or plunger (11)-'forn1ed with a head (12). The insertion or removal of the plunger functions respectively to producta louder or softer quality of reproduction than would otherwise be obtained; it being known in the art that the tone volume is in direct proportion to the size and resistivity of the needle.
It isbelieved that the operation and advantages of my invention are apparent from the foregoing, but it is desired to again emphasize the peculiar formation of'the cenapplied to a graphophone reproducer of tral cavity, the plunger or pin, and the rela- 55 conventional type,
, Figure 2 is a longitudinal sectional view tive angular arrangement of the respective parts of the needle and the point of ridium or other metal which are productive of the improved quality of reproduction attributed to i'.- I 1 While in the foregoing there has been illustrated and described such combination and arrangement of elements as constitute .the preferred embodiments of my invention,
it is neverthclessidesired to emphasize the n fact thatinterpretation of the invention should only be conclusive when made in the light of the subjoined claims.v
Having described my invention and its objects with such attention to detail as will thoroughly acquaint one skilled in the art with its construction and advantages, I clai m':- 1
1- A tubular graphophone needle for use with a reproducer, and having a body portion positioned to be inclined toward a record body and bent intermediate its ends to reduce the angular inclination of the lower end of the needle with respectto the record body, said body portion having its lower end gradually reduced in cross-section, an,
iridum point on the end of the reduced portion and having an angular inclination reverse to the angular inclination of the lower end of the'body portion and laterally with respect -to said body portion whereby to eflectively contact with the groove of a record, and'a member adapted to be inserted into the tubular portion of the needle to partially fill the same to intensify the reproduction of tones by the 'needle without effecting reproduction of stray noises incident to contact of the needle with a record.
'2. A graphophone needle for use with a reproduce'r, comprising a body portion positioned to be inclined toward a record and formed with a central" cavity extending from end to end thereof whereby to soften the tones reproduced by the needle, said body portion being formed with a bendintermediate its; length and gradually reduced from the bent portion to the lower end of the needle, a conical iridium point on fthe reduced end of the body portion and having an angular inclination reverse to the angular inclination of the lower end of the body portion and laterally with respect to said body portion whereby to provide a more effective contact with the groove, and a freely removable plunger of less length than the body portion and adapted to be inserted in-the cavity above the bend in the body to partially fill the same to intensify the reproduction of tones by the needle without effecting reproduction of stray noises incidefined.
In testimony whereof, I affix my signature hereunto.
