GRAMOPHONE OR TALKING-MACHINE.

I SPECIFICATION forming part of Letters Patent No. 759,348, dated may 10, 1904.

Application filed April 26, 1902.

To all whom, it may concern:

Be it known that I, ALFRED-CLARK, a citi-- zen of the United States of America, and a resident of the city of Paris, Republic of France, have invented certain new and useful Improvements in Sound "Recording and Reproducing Machines, of which the following is a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to sound recording and reproducing machines commonly known in the trade as disk machines; and the main object of my invention is to so improve on the machines heretofore made that the user of a machine may use the same machine for making records as well as for reproducing records of sound-vibrations.

Heretofore the sale on disk talking-machines was limited, owing to the fact that persons desiring to make their own records, as well as to reproduce them, were obliged to use a complicated and very expensive machine.

' In carrying my invention into effect I provide a disk record-tablet made wholly or partially of wax or wax-like material or any other material capable of being cut into by the recording point or stylus, so as to remove or displace the material of the tablet in forming'the record-groove, and in order to provide a simple form of sound-box which may be readily employed in the making and re-.

production of said record andone capable of simple operation I provide a diaphragm car ried, preferably, by a tubular supporting-arm capable of horizontal and vertical movement relative to the disk, and which diaphragm is reproducing tracer, either of whichmay be brought into operative position. In the preferred form this diaphragm is arranged to rotate on its supporting-arm to bring either the stylus or tracer into operative position, and I also provide a locking device for locking the diaphragm or its supporting-arm against horizontal movement when the recording-point is in operative position, it being understood that when the reproducing-traceris in operative position the diaphragm will be free to move horizontally with respect to the disk, so as to Serial No. 104,744. (No model.)

insure the accurate tracking of the tracer in the record-groove. It will also be understood that the provision for vertical movement of the diaphragm-supporting arm is designed to overcome irregularities in the surface of the disk. The movement of the diaphragm-supporting arm is independent of the horn-support, and in no wise is it affected by the same. The diaphragm-supporting arm being connected to the horn-support by a universal joint permits the diaphragm to have lateral and vertical movement independent of the lateral and vertical movement of the horn and horn-support, and the movement of the horn in no wise affects the movement of the diaphragm while the said diaphragm is being fed across the record by the record-groove. Owing to this construction the diaphragm is compelled to more readily follow the sinuosities of the record-groove and is not affected by the weight of the horn or its support.

While the essential and characteristic features of my invention are necessarily susceptible of modification, the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 represents a plan view of a part of a talking-machine embodying my invention. Fig. 2 represents a vertical section taken on line 00 y in- Fig. 1. Fig. 3 represents a sectional view of the diaphragm. Fig. 4 represents a plan view of the same. Figs.

5 and 6 represent sectional viewsof the dia phragm-tube, showing the play ofthe tube in its vertical and horizontal directions. Fig.

Fig. 9 represents a side elevation of my improved recording and reproducing device arranged for reproducing, and illustrating an ad ustable horn-support, and Fig. 10 is an end elevation. V v

3 disk.

0 by this construction andby material, preferably metal. The clampingcap B is provided with a spiral guidinggroove which leads to the center of said cap. Engaging with the spiral groove of the clamp- 5 ing-cap is a guide-pin C, which is connected in any well-known manner to the arm D of the sound-box G.

The sound-box G consists of ailiaphragm a? and a rubber gasket '10, which are attached Attached .to the diaphragm .2 is a plate or support 0, provided with both a recording-point q and a reproducing-point r.

The rotary diaphragm-support n is provided 5 with a socket t, which is fitted to the diaphragm-tube m by means of a pin 11-, which engages with the groove 1' in said tube, thereby permitting the diaphragm to be turned at right angles to its central axis, so as to bring the recording-point q or the reproducing point r at pleasure into contact with the record-disk F. p is a weight secured to the diaphragm-support 11 and which engages with the catch p on the lever Z, thereby securing the diaphragm rigidly when so desired. The lever I also serves the purpose of raising the diaphragm when required in order to avoid-any possible destructions of the impressions on the recordlVhen the weight 7) is in engagement with the catch 1) on the lever 7, the diaphragm is absolutely rigid, so that no horizontal displacement is possible on the pivot j of the diaphragm-tube m.

It is well known that when a diaphragm is to be used for reproducing purposes more pressure is required than when used for recording purposes, and it is for this reason that 4 I secure the weight 1) to the diaphragm-support 21, which when it is moved away from its center or support, which in this case is the reproducing-point r, Fig. 8, it produces additional weight to the point "r and morcdownward pressure upon the reproducing-point,

and consequently the latter is more firmly applied to the disk than when recording. The weight 2) being no longer in engagement with the catch p permits a very slight motion in a 5 horizontal direction to the tubes of the. diaphragm. This horizontal movement is just suflicient to permit the reproducing-point r to actually follow the path of the spiral groove.

In Fig. 7 it will be noticed that the weight p is in engagement with the catch p of the lever Z, and is therefore nearer the center or support, which in this case is the recordingpointq, and it therefore produces less pressure upon the point It will be noted that the relative location of the recording-point near the center of the diaphragm and the reproducing-point away from such center a considerable excess of pressure is exerted on the reproducing- 5 point during reproduction over that which is exerted on the recording-point during the recording process.

It will be seen that by simply turning the rotary diaphragm-support '22 with the recorder from Fig. 7 it will be converted intoa reproducer, as shown in Fig. 8.

Referring to Figs. 5 and Got the drawings, on represents the diaphragm-tube, to which is fitted a ring Z by means of a pin or stud 7'. The ring 1' is passed over the extension of the articulated joint 7: in such a manner that the pin j engages with a slot in the said extension. This construction serves to prevent any displacement in the horizontal direction of the interior of the tubes and enables the diaphragm having attached thereto both recording and reproducing points to have a very slight lateral motion in the plane of the disk. By this construction it will be seen that the sound-box and its parts are free to swing vertically upon the pin 2'. and horizontally upon the pin j when the reproducing-tracer' is in operative relation with the record-tablet; but they are constrained to move vertically only when the recording-stylus is in such operative relation. Y

ln talking-machines of the class described it is necessary to provide an amplifying-horn and a support for the same. In Fig. 9 l have shown my improved device as supported at the end of such a horn, (shown in dotted line s the horn in turn being supported by a universal connection at the outer end of the arm (Z, extending from the case of the machine (not shown) as usual. This arm (I has anupturned outer end provided with a socket, into which is inserted the stud e of the yoke (2, thus permitting horizontal movement of the horn-support. The yoke e carries a pivoted cross-head I), through which passes the adjusting-rod (1,, held in place by the set-screw c. The horn is inserted in the clamping-ring g, which is supported at 'the outer end of the rod (2- and carries the diaphragm tube 212 and its connections, as shown. btopsfare secured in the cross-head b to limit the movement of horn-support when the diaphragmpoints are not in engagement withthe record.

These stops also serve to hold the sound-box at the proper angle with the record by their engaging the cross-bar of the yoke b. l

I am aware that changes may be made in various arrangements and combinations of the parts wi'thoutdeparting from the scope of my invention. Hence I do not limit my invention to the exact arrangement and combination of the parts as described, nor do I confine myself to the exact shape and configuration of the same.
