TALKING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,466, dated April 26, 1904.

Application filed. March 30, 1908. Serial No. 150,128. (No model.) I 7 T0 aZZ whom it may concern.-

Be it known that I, EDWARD T. PALMER, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Talking-Machines, of which the following is a specification.

My invention relates to a new and useful improvement in phonographic machines, and has for its object to provide a machine for reproducing the sounds from a record, the machine to be so constructed as to be sold at a comparatively low price and yet be very effective in reproducing the sounds from the record.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which Figure 1 represents a side elevation of the machine; Fig. 2, a plan view of the same; Fig. 3, aside elevation of the arm and needle which rests upon the record; Fig. 4, a section on the line 4 4 of Fig. 3; Fig. 5, a section on the line 5 5 of Fig. 2.

In all phonographic machines for reproducing sound from a disk record the machines are expensive, and therefore cannot be purchased by persons of limited means. Therefore I have provided a-machine which can be made and sold at a comparatively low price and is intended as a toy, but will reproduce the sounds nearly if not quite as well as the more expensive machines.

A represents the case in which the machine may beheld.

B represents a base provided with a spindle upon which the disk 0 is held.

D is a thumb-screw for securing the disk upon the spindle.

E is a crank also secured to the disk by the thumb-screw, whereby the disk record may be turned by hand or otherwise.

F is a block secured to the bottom of the case A, and this block is provided with a vertical hole in which the pin G is adapted to fit. The upper end of the pin G is formed as indicated at G, and between the prongs of the form the arms H are pivoted by means of pointed screws I or otherwise which pass through the prongs and into cavities upon each side of the arm. Thus the arm H is pivoted both horizontally and vertically.

J represents the horn, which is preferably made of paper, but may be made of celluloid or any other suitable material, and the smaller end of this horn is secured in any suitable manner to the outer end of the arm H. In the drawings the arm H is shown bifurcated at the end and the smaller end of the horn thrust between the two prongs. The arm H is preferably made of wood, but can be made of any other suitable material, such as metal, hard rubber, &c.

K is the needle-socket, which is set part way into the outer end of one of the prongs of the arm H and is set at an angle, as shown in Fig. 1. I

L represents the needle, which is secured in the socket by a set-screw M.

The lines which are cut in the disk record, as is well known, are cut spirally, and the needle lying within these lines will be gradually moved toward the center as the disk record is revolved. Thus in my machine it is only necessary to secure any of the standard disk records to the spindle of the base B. Then by inserting the pin G into the hole in the block F and allowing the needle to rest near the periphery of the record and by turning the record in the direction of the arrow in Fig. 2 the needle will follow the lines and swing upon the pin G toward the center of the record until the record has been entirely played, and the vibrations will be transmitted through the needle to the arm and horn, so as to reproduce the sound.

Of course I am aware that the same general principle of all disk-record machines is utilized by me in this machine; wish to claim the principle broadly, but only wish to claim my particular construction,

which enables me to do away with the soundbox and manufacture the machine at a comparatively small cost, and 1 do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully. described my invention, what I claim as new and useful is 1. In a phonographic machine, the combination of a disk record mounted so as to rotate upon a vertical spindle, a crank for turning the same, a block located stationary beyond the periphery of the disk, a pin fitting loosely within a vertical hole in the block, the upper end of the pin being bifurcated, an arm, one end of which is pivoted between the prongs of the bifurcated end of the pin so that said arm will swing vertically, the outer end of the arm being bifurcated, a horn, the smaller end of which is held between the prongs of the bifurcated end of the arm, a removable needle secured at the outer end of one of the prongs of the arm at an angle and adapted to rest upon the record, as specified.

2. 1n aphonographic machine, a case, a base secured to the bottom of the case, a spindle extending up vertically from the base, a disk record secured so as to revolve upon said spindle, a thumb-screw threaded upon the upbut I do not per end of the spindle for securing the ree- 0rd in place, a crank connected to the center of the record for turning the same, a block secured to the bottom of the case outside the periphery of the record, a pin fitting vertically within the block so as to turn within the same, the upper end of the pin being bifurcated, a wooden arm, one end of which extends between the prongs of the bifurcated end of the pin,pointed screws threaded through the prongs, and into each side of the arm so as to pivot the same, the outer end of the arm being bifurcated, a paper horn, the smaller end of which is thrust and held between the prongs of the arm, a needle-socket secured at an angle in the outer end of one of the prongs of the arm, a needle fitting in the socket and resting upon the record, and a set-screw for securing the needle in the socket, as specified.

3. A sound-reproducing machine comprising a swingingfork adapted to receive and transmit sound-vibrations, and a horn carried by said fork and adapted to receive and transmit sound-vibrations transmitted to said fork, as specified.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
