Anplieation filed au ust 8, 1908. Serial No. 447,569.

To may concern:

Be it known that I, MINARD ARTHUR Pos-' sons, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga' and State of Ohio, have invented certain new and useful Improvements in Needle-Holders for Sound-Boxes, of which the'following is a specification, reference being had therein to the accompanying drawing.

' My invention relates to improvements in- V needle holders for sound boxes.

The object of my invention is to provide understood t at anyform of sound boxes a needleholder adapted to support a rotatable needle and said holder adapted to be secured in the'needle receiving socket of the sound box. 1

Another object of my invention is to provide a needle holder of this character which can be made independent of the sound box and secured within the needle receiving socket of the ordinary sound box.

In the accompanying drawings, Figure 1 is a side view of my improved needle holder attached to the ordinary sound boxnow in use. Fig. 2 is an edge view of Fig. 1 looking in the dlrectionof the arrow shown in Fig. 1. Fig. 3 is an edge view looking in the opposite direction from-Fig. 2. Fig, 4 is an enlarged perspective view of the needle holder as it would be manufactured and sold to be adapted to the ordinary sound box. Fig. 5 is an enlarged sectional view showing the swivel connection of the thumb-nut with the. swinging arm.

Referring now to the drawings, 1 repre-.

sents an ordinary sound 'box having the usual arm 2 connected to the center of the diaphragm 3, the outer end of said arm connected to the spring operated member 4 carrying the needle recelving socket 5. In sound boxes of this character the needle is either secured in the said socket by a set screw 6 or by a' cam lever 7, and in some instances-by both the set screw and thecam lever. While I have shown and describedthis form of-sound boxes to show/the a. p li cation of m needle support, it w' be may be used, as sound boxes all use a needle receiving socket. Therefore it will be seen thatmy improved needle holder can be readily secured to any sound box using a needle socket.

My improved needle holder consists of ashank 8 adapted to enter the needle receivrotatable shaft .17;

ing socket of the sound boxand secured therein by means of the said screw or cam' lever in the same manner that-the ordinary needle is secured in the socket. The lower end of the shank 8 has secured firmly and rigidly therewith a curvedplatje 9, and said curved plate intermediate its ends is provided with a downwardly extending arm 10.

The lower end of said arm is provided with an inwardly extending screw threaded stud 11, and upon which is mounted the disk needle 12. This needle as shown is stamped from a piece of sheet metalhaviiig serra-' tions in its outer periphery forming a series of independent needles whereby the needle does not have to be moved for each record.

The upper edge of the curved plate 9 opposite the arm 10 is provided with the lugs 13 and 14, between which is mounted a swinging arm'15, the lower end of which is and surround the outer end thereof. Swiveled within the lower end of said arm 15 1s a thumb nut 16 having at its inner end an internally screw threaded socket 1 7, which is adapted to be screwed to the outer end of the stud 11 and frictionally clamp theneedle 12 against-the arm 10 and hold the same against rotation. The thumb nut 16 as will be understood, is not screwed tight enough tov absolutely prevent this needle 12 from being rotated, but sutliciently tight to prevent it from being moved by frictional contact with the record disk of the talking ma-- chine, and therefore when the .needle is set, it is held in said position.

In order to provide means for rotating the adapted to swing down opposite the stud 11" disk needle a distance to bring a different point in contact with the record disk, I provide the lower end ofthe arm 9 with an en- By the construction herein set forth it will be seen that I have produced a needle holder adapted torem'ovably hold a disk needle in Such a position thatit will assume the proper position upon the record disk and at, the

same time allowin of the ready removal of the needle when a the points have been used,

and the whole device adapted to be remov- ,ably attached to the ordinary sound box as heretofore set forth.

Having thus fully described the invention what is claimed as new, is

1. The combination with a sound box having the usual needle receiving socket, of a needle holder remoyably secured in said socket, a rotatable needle removably secured to said holder and having a series of needle points on its outer eriphery, and means carried by the holder for rotating the needle.

2. The combination with a sound .box having the usual needle receiving socket, of a needle holder comprising a shank adapted to be.clamped in the needle receiving socket, a downwardly extending arm rigidly carried by the lower end of said shank, a hori-.

zontal stud carried by said'arm, a rotatable -needle mounted on said stud, av swinging member carried by the arm, a thumb nut swiveled in the lower end of the swinging arm and adapted to be screwedon the stud on the outside of the needle, a rotatable shaft carried by the arm and means carried by the shaft for rotating the needle.

. 3; Thecombination with a sound box havmg a needle receiving socket, of a needle holdercomprising a shank adaptedto be ate ts ends, a thumb nut swiveled in the lower end of said member and adapted to be screwed upon the stud and clamping the disk needle in its operative position, a shaft rotatably mounted in the lower end of said arm, a small disk carried by the inner-end of said shaft, 2. pin carried by t e inner face i of said disk and adapted to engage the disk needle and rotate the same a distance suflicient to bring another point of the needle in position on the record during each rotation of the shaft.

In testimony whereof I afiix my signature in" presence 0' two witnesses.
