Specification of Letters Patent.

Application filed August 31. 1906. Serial No 332,729-

To all whom it may concern.- f

Be it known that I, EDWARD T. PALMER, a I nited States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Talking-Machines, of which the following is a specification.

One object of my invention is to provide a sound recording and reproducing machine in which the stylus and its supporting member shall be revolubly supported relativel to a stationary record, which may be of t e ordin ary disk type. i

It is further desired to provide a device commonly known as a talking machine, especially designed for use with records of the disk form, which shall have but few parts and these of a relatively simple and inexpensivenature. I also desire to produce a talking machine which shall require but little attention and be of such a nature as to not easily get out of order.

5 These objects I attain as hereinafter set forth, reference being had to the accompanying drawing, in which v Figure 1, is a plan view of the machine made in accordance with my invention; Fig. 2, is a side elevation, partly in section, of the device shown in Fig. 1 Fig. 3, is an end view; Fig. 4, is a sectional view on the line 44, Fig. 2; Fig. 5, is a perspective view of the stylus; and Figs. 6 and 7, are views of a modification.

In the above drawing, A is a base or stand of any suitable form havin at its center a bearing in which is remova ly supported a vertical spindle b. This spindle has at its upper end a crank b, there being also fixed zontal plane, a relatively heavy and preferably metallic plate B, which may advantageously be of the elongated shape shown in the figures, although I do not limit myself to such form. On one of the lobes of this plate is carried a U-shapedor forked piece b inov able on a vertical pivot. A block C is pivoted to the arms of the U- shaped piece 12 as illustrated clearly in Figs.- 2 and 3, and on the end of this block is secured the horn D, the horn in the present instance having a reduced portion d which passes over the end of the block O. and is prevented from turning-thereon by a pin 0 on the block which extends into a slot cl in the horn.

the base A, preferably on. a sheet of felt or 1 other soft material, as indicated in Fig. 2. The record disk is stationary and the horn with the stylus turn on the spindle bas a pivot.

Mounted between a block tering a cavity in the block, as illustrated in This spring tends to keep the stylus down onto the record, overcoming the centrifugal force due to the rotation of the metallic plate B which carries the horn and stylus.

It will be seen that there is a direct connection between the stylus and the horn, thus I dispense with an intermediate carrier.

In some instances the block C may be permanently secured to they horn D, but I preferably make it detachable, as shown.

In Figs. 6 and 7 I have illustrated a modification in which there is a saw kerf out in the block G into which pro'ects a standard extending from the pivot plate I). In Fig. 6, I have also shown a flat spring z" in place of the coiled spring illustrated in Fig. 2. The block C in this instance is slotted at 0 so that the end of the block will yield when the projection b and the C is a coiled spring 45, the spring enhorn is forced over it, thus there is sufiicient elasticity in the block to, hold the horn rigidly in position without other fastenings.

When it is desired to the spindle b .with the plate B and its parts is removed from the base A, after which a reoord disk F is placed on said base concentric with the bearing 6 said spindle?) and its attached parts are then replaced and the stylus e permitted to rest upon the disk F. On revolving the plate B y turning the crank b the stylus, which is carried by the horn, fol lows the spiral record groove in the disk, causing vibration of the horn which in turn causes sound waves to be produced. The

operate the machine sound waves are reproductions of the waves originally recorded on the disk, being due to the co-operation of the stylus and its parts with the record in the manner understood by those skilled in the art.

In some instances any suitable device whicli'will cause the sound waves to be reproduced can be used in place. of the. horn, although I prefer to use a horn in most instances.
