T6 all whomit may concern:

Be. it known that I, Jams A. Rsnnrrr, a citizen of the United States, residing in the city of Yokohama, Empire'of Japan, have- 5 mvented'hertain new and useful Improvements inTalking-Machines, of which the following is a specification. 1 a

This invention relates to talking-machines, and its object is to efiect certain improveuse, whereby a faithful reproduction of the recorded sounds is obtained, and whereby the tone of the reproduced sounds may be 7 I have illustrated the preferred embodis. ment of my invention in the accompanying drawings, in which'-. r Figure l is a top view of the tone-arm;

' I away and sectioned in part Fig. 3 is a front view of the sound-box and tone-arm; Fig. i is a perspective view of the lifting device for the sound-box; Fig. 5 is a sectionalsound-box and tonehrm; Figs. 6, 7, 8 and Qare detail views, illustrating the holder t'orjthe stylusg Fig. 10 is asectional elevationof the supporting arm for the toneof this supportin arm; Fig. 12 is a side view of the soun -box, showing the soundmodifi'er applied thereto; Fig. 13 is an end view of the sound-box, and Fig. 14 is asecs Referring first to Figs. 1 to 5 inclusive, 1 indicates the tapering tone-arm, having its larger end secured 'to a coupling-member 2, which supports the tone-arm so that the latturn freelyv about a vertical axis. The

sound-box is shown at 3. This sound-box is connected to a short tube 4, the end of which enters and is secured within an open end of the tone-arm 1 enters and is secured Within an opening" in a cylindrical iece 6, which is adapted to be received wit in the shell 5. When the sound-box is in operative position, the tube 1 is in axial alinement with; the openings through the piece 6 and the tone-arm 1, so that a passageway for the sound-Waves free from obstructions is provided. On one side of the cylindrical pics 6, is a cylindrical extension 7 of somewhat smaller diameter than the body of -the piece 6, and at opposite sides of the piece 6 are provided pivot-pins 8 extending into depressions. in the shell 5, so that thelatter may hum freely upon 'the'pie'ce 6. A split clamping-ring, preferably of the form shown in Fig. 4, is provided upon the cylin 'dricalgjextension 7 of the piece 6. .Thisring 9 hasfa fingcrpiece 10, whereby it maybe turned relatively to the piece 6, .andalso it has a projection 11 adapted to engagethe Wall 12 of the shell 5. Normally ,the ring 9 clamps the extension 7 so tightly that it will not-move thereon, but by applying a small amount of pressure to the fin erpiece 10 the grip of the split ring upon the extension 7 may be relieved somewhat and the ring I turned thereon. When the ring is so turned,

the projection 11 engages the Wall'12 and turns the shell 5 upon the piece 6,: thereby raising the sound-box 3 sofas to 'lift't-he stylus from the sound-record, as v indicated by the dotted lines in Fig. 2. When the j sound-box has been so raised and thev fingerpiece 10 released, the split ring 9 Willgrip the extension 7 so tightly that it will not move thereon, and the sound-box will be supported in this raised position, due to the fact that the Wall 12 of the shell 5, bears against the projection 110i the clamp.

lteierring to Figs. 6, 7, 8 and 9, the means employed for securing the stylus in its holder will be described. The stylus-holder 13 has a; lengthwise openin therein toreceive the stylus 14, and it a so has a transverse opening which is tapered at one end and which is adapted to receive a pin 15 correspondingly tapered at one end. .At its opposite end, the pinv 1'5hasa head 16 secured thereto and a spirahspring 17 is coiled .95 about the pin 15. In order to secure the stylus 14 in the opening in theholder 13, it I is only necessary to move the pin. 15 in the direction of its axis hypressing u on the head 16; then insert the stylus 1 in its opening, and then release the pin 15, whereupon the spring 1? will move the pinin then I direction of its. length until the tapered side opening in the pin 15,, and when the head 16 is released and the pin is moved by the spring 17, the stylus 14: will be gripped on opposite sides by the converging walls of the opening in the pin 15.

The tone-arm is pivotally mounted upon a supporting arm 18 constructed as sho \vn in Figs. 10 and 11 In securing this arm to the motor-box of the machine, I provide a metallic plate 19 adapted to be permanently secured to the motor-box of the machine and so arranged that the arm 18 may be readily mounted thereon or detached therefrom. To this end, I. provide upon the member 19 horizontal supporting surfaces 20 and 21, the former having a pin 22 projecting upwardly therefrom and the latter having two openings extending downwardly' therefrom. The lower end of the arm 18 is formed to coact with this member 19, and for this purpose has an opening formed in the bottom thereof adapted to receive the pin 22 and two pins 23 extending I downwardly from a projecting portion 24.

Referring now to Figs. 12, 13 and 14, I will describe the means employed for modifying the tone of thereproduced sounds. The sound-box has a stylus-lever 25' of the usual or any suitable construction, adapted to be operated by the diaphragm 26 of the sound-box. To provide for modifying the sounds, I employ a sheet-metal support 27 having three arms which may be carried over and folded upon the sound-box, as shown at 28. Secured to this frame 27, is a stud 29, having a threaded opening therein adapted to receive a threaded pin 30. At its inner end, this pin carries a pad 31 of soft material, such as felt. To the outer end of the pin 30, is secured an operating handle 32, andthis handle may be extended .to form an index 33 cooperating with a suitable scale on the frame 27. By turning the handie 32, it will be seen that the pad 31 will be moved more or less into coact-ion, with the'stylus-lever 25, so as to dampen the movements thereof in response to the vibrations of the diaphragm 26. By moving the handle 32 in this way, such an adjustment of the position of the pad 31 may be obtained as will make the reproduced sounds of the desired amplitude.

Having now described my invention, What I claim as new therein and desire to secure by Letters Patent is as follows 1. In a talking-machine, a tubular soundconveyer, a sound-box, a tubular extension on'the sound-box, means for connecting the end of said extension to the end of said conveyer and in axial aline'ment therewith, comprising a cylindrical member secured to one of said parts and a' shell secured to the other and having said member pi'rotally mounted therein, and a clamp movable upon said member adapted to grip the same and also adapted to coact with a part on said shell to position the shell relatively to the member, substantially as set forth.

In a talking-machine, a tubular soundconveyer, a sound-box, a tubular extension on the sound-box, means for connecting the end of said extension to the end of said conveyer and in axial alinement therewith, comprising a cylindrical member secured to one of said parts and a shell secured to the other and having said member pivotally mounted therein, a clamp on said member adapted to grip the same, a handle on the clamp, and coacting engaging projections on .the clamp and said shell, substantially as set forth.

3. In a talking-machine, a tubular soundconveyer, a sound-box, a tubular extension on the sound-box, means for connecting the end of said extension to the end of said conveyer and in axial alinement therewith, comprising a cylindrical member secured tr one of'said parts and a shell secured to the other and having said member pivotally mounted therein, a split ring on said member adapted to grip the same, a handle on said ring for opening the-latter and moving it upon the member, and'coacting engaging portions on the ring and on said shell, substantially as set forth.

. i. In a talking-machine, a tubular soundconveyer, a sound-box, a tubular extension on the sound-box, means for connectingthe end of said extension to the'end of said conveyer and in axial alinement therewith,

comprising a cylindrical member secured to one of said parts and closed at. its ends, and a shell secured to the other of said parts, having an opening on one side and having said member pivotally mounted therein, and a clamp movable upon said member projecting through said opening in the shell and adapted to be moved about said 'memher and to engage and actuate said shell, substantially as set forth.

This specification signed and witnessed this 5th day of February, 1910.
