My United States Patent, No. 741,543, of

October 13, 1903, shows and describes a rotatable needle and a certain form of means for rotating it. My present invention involves a specific means for revolving the needle, involvesmeans for automatically feeding the needle longitudinally, and also certain details of construction, neither of which is shown in my prior patent.

Referringnow to my resent improvements, 1 indicates a soun -box of the ordinary construction. The diaphragm 2 has the usual connection 3 therewith, the opposite end of the connection being connected with a member 4, which is supported or rather connected with a bracket 5 throughthe medium of screws 6 and springs 7. Bigidl connected with the member 4 is a jawhoiding extension 8. This extension 8 carries the adjustable jaws 9, the outer ends 10 of which are suitably shaped to clamp the pointed end of the needle 11, as shown in Fig. 8. sion 8 is a longitudinal needle passage-way 12, throu h which the needle 11 may freely rotate and move longitudinally.

Projecting from the side of the sound-box 1 is a suitable bracket 14, in which is journaled a rotatable sleeve or equivalent member 15, through which passes a needle-carr ing member 16. This member 16 is provide with an external longitudinal groov 111 which apin or feather 18, carried by the member 15, engages. The said groove 17 extends throughout the length of the needle-carrying member 16 and permits the said member to be moved longitudinally through the rotating b r 15, but looks the members and 16 against independent rotation. A cap 19 is secured to the up or end of the rotatable member 15 through the medium of a pin or screw 20, thus locking these parts together and making them practically one element, so far as operation is concerned, after the parts are assembled. The cap being removable, however, it enables the member 15 to be laced in position within the bracket 14 or to he removed therefrom.

Secured to the lower end of the member 15 is a gear 21, and this gear 21 meshes loosely with a gear 22, which is attached to the upper end of a shaft 23. This shaft 23 is journaledin a suitable bracket 24. J ournaled to the lower end of the bracket 24 is an actuating-wheel 25, preferably carrying a rubber rim 26 for engagement with the record 27. Concentrically connected with the actuatingwheel is a warm 28, and this worm is in operative engagement with a worm-gear 29,

attached to the lower end ofthe previouslymentioned shaft 23. The needle 11 is connected with the needle-carrying member 16 by passing into alongitudinal opening 30 therein and being held by a thumb clampscrew 31.

From the foregoing description it will be understood that as the record rotates the wheel 25 in engagement therewith is rotated,

ICC

tated and in turn rotates the needle-carrying member 16. The needle being rotated and supported at an inclination the point thereof will alwaysbe tapered and will accurately follow the indentations of the record and will at all times make as good a reproduction as a new needle and, in fact, better, because the needle is not dulled by contact with the record, as in a non-rotatable needle.

Thus far I have only described that part of my present invention which pertains to the means for rotating the needle irrespective of Whether the needle is adjusted longitudinally, automatically, or otherwise. The primary object of rotating the needle is to avoid the necessity of using a new needle for each record, as is the case with anon-rotatable needle,

- and to permit the needle to be continuously used until it becomes too short to be held by the clamping member. Ittherefore follows that-to obtain the full advantage of a rotataas it is worn away.

ble needle it must be moved longitudinally My previously-mentloned patent shows means whereby the 0ptor may adjust the needle. I will now expla n that part of my present invention which accoinplishes the automatic adjustment or longitudinal movement of the needle as it 1s worn ma The t ifiure of my present invention for ad ustingthe needle longitudinally may be varied in detail of construction without departing fromthe spirit and-scope of my invention, since, so far asTam ar a rotatable and automatically longitudi allyadjusted needle for talking-machines hasinot been previously devised. show for the purpose of enabling my" inVen tion to be understood one convenient form for accomplishing automatically the adjust ment of a rotatable needle. The particular form here shown consists in pivoting the bracket 24, which carries the operatingwheel 25, and the pivotal point here shown is indicated at 32in a suitable support or bracket 33, which is secured to the sound-box 1,- whereby the bracket and wheel are permitted to swing or oscillate upon the said pivotal point. A spring 34 engages the'bracket and serves to hold the wheel 25 in contact with the record 27. As is understood'by those skilled in this art, the sound-box is supported by the needle, which in turn is in engagement with the'record 27. The wheel 25 is therefore yieldingly held in contact with the record 27, so that the sound-box 1 may move downward as the point of the needle wears away. In the form here shown the automatic longitudinal adjustment of. the needle is controlled by the movement of the soundbox independent of the wheel and bracket,

which are movably supported by the soundbox, the movement of the sound-box being occasioned, as just stated, by the wearin away of the point of the needle.

I therefore herein\ The downward movement of the soundbox 1 in the form of mechanism herein disclosed effects the automatic longitudinal ad justment of the needle through the following instrumentalities: Loosely swiveled to the 0 upper end of the member 15 is a screw-head or ratchet 33, and the needle-carrying member 1 6 is eXternallyscrew-threaded for the purpose of engaging the internal screw-threads of the opening 34 in said ratchet or screwhead 33. A. locking member 35 is provided and is here shown in the'form of a pivoted lever, one end 36 of which is adapted to be moved into and .out of engagement with the roughened or ratchet-shaped outer surface 37 of the said screw-head 33 The opposite end 38 of the said lever 35 is adapted to be engaged by a projection,- screw, or pin 39, but preferably a screw, whereby it is capable of adjustment. mally holding the end .36 of the lever 35 out of engagement with the screw-head 33, and the means here shown consists of a suitable spring 40. The means here illustrated for swiveling the screw-head 33 to the member 0 19, which-is rigidly connected to the member. 15, consists in providing the member 19 with a circumferential groove 41 and the screwhead with a pin or projection 42, loosely engaging the said groove. facilitating the description and assisting in the understanding of this automatic feature of my invention the diagrammatic View, Fig. 7, will be referred to. The solid lines of this diagrammatic view show the parts in their normal positions and the automatic adjusting feature out of operation. The dotted --;lines show the position of the parts when the automatic feature of adjusting the needle longitudinally is in operation. the positipn of the parts, as shown in solid lines, the fi' ction between the screw-threaded portions of thehead 33 and the needle-carrying member 16 is sufficient to cause the screw-head to rota The needle being the su ort for the soundboX, as the point of the n' dle wears away the sound-box will move'dow i ward to the position indicated in dotted lines, nd which will carry the screw or projection 2iln con :115

From the foregoing it will 1 o Means is provided for nor- 85 For the purpose of 5 Referring to' with the member 16. no

be understood that the needle will be longitudinally adjusted, as may become necessary on account of the wearing away thereof, and without any attention on the part of the operator.

For the purpose of enabling a long needle to be used the member 16 has the opening 30, extending entirely .therethrough, which will enable a long needle to be held thereby.

In starting the machine with this invention the needlewill have its pointedend adjusted to the proper distance beyond the jaws 9 and with the needlecarrying member in its uppermost position and the needle clamped therein by the thumb-screw 31. The machine is now adapted to operate without any attention on the part of the operator, so far as the needle is concerned, until-the needle has been worn away sufliciently to cause the lower end of the needle-carrying member 16 to engage the upper end of the jaw-carrying extension 8. At this point it will be necessary to loosen the thumb-screw 31 and to move the needle-holding member 16 to its outermost position, which can be uickly done byrotating the screw-head 33. 'I his being done the clamping-screw 31 is again tight ened and the machine is ready for further automatic operation.

In order to get the proper result, the needle must be tightly clamped by the jaws 9, so that it will not have any independent movement therein. Continued long service may cause the engaging portion of the-jaws to be worn by the rotation of the need e therein, and I have provided means for permitting the adjustment of these jaws to take up any Wear thereof. This means consists in arranging the jaws 9 in the extension 8 at an angle and providing adjusting-screws 43. By forcing the jaws outward through the medium of these screws 43, owing to their relative angfilar positions, will cause their outer ends to be brought needle to be tightly clam ed.

In order to permit the ee springing move ment of the gear 22 in respect to the gear 21 as the bracket. 24 swings upon its pivotal point, I preferably make the teeth of the gear 22 of such a shape as to permit this springing movement, as illustrated in Fig. 4.
