TALKING MACHINE.

Specification of Letters Patent. Patented Apr, 11, 1922,

Original application filed July 2, 1915, Serial No. 87,731. Divided and this application filed July 6, 1917.

Serial No. 178,973.

To all whom it may concern:

Be it known that we, MERVIN E. LYLE, JOHN J. SGULLY, and FRANK L. CAPPs, citizens of the United States of America, and residents of Bridgeport, Connecticut, have invented a new and useful Improvement in Talking Machines, which invention is fully set forth in the following specification.

This invention relates to talkin machines, and it has for its object to prov1de a tonearm and mounting therefor that are simple in construction, inexpensive to manufacture,

easy to assemble, and efiicient in operation,

this application bein a division of our application Serial No. 3 ,731, filed July 2, 1915, entitled Talking machines, patented February 4, 1919, Number 1,293,489.

The inventive idea is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustrating the invention, is shown on the accompanying drawing, but it is to be expressly understood that such drawing is for the purpose of illustration onl and not for the purpose of defining the limits of the invention, reference being had to the appended claims for that purpose.

In said drawing Fig. 1 is a perspective view of a talking machlne embodying one form of the invention;

Fig. 2 is a vertical sectional View through the tone-arm support.

Referring to the drawing, in which like reference numerals indicate corresponding parts in both'views, 1 designates a talking machine cabinet of any suitable construction, bein shown as of that type wherein an amp ifier 2 is enclosed within the same. Also mounted within the casin 1 is any suitable form of motor (not sown), the motor being provided with the usual winding crank 3. 4 desi ates the usual turntable, 5 a record-tab et, and 6 is a soundbox of any suitable construction.

Over an aperture suitably positioned in the top plate 7 of casing 1, and shown as situated in one corner thereof, is a tone-arm support 8 provided with two oppositely disposed horizontal slots 9, within which rest the tone-arm 12, sai one-arm at its other The spherical enlargement "11 fits closely within the upper'portion of the supports but with suflicient clearance so as to permit the tone-arm to turn freely therein about vertical and horizontal axes. This construction enables the tone-arm to have universal movement upon its bearing without provid- 1ng any opemng the interior of'the sound conduit.

Within the tone-arm support 8 and beneaththe spherical enlargement 11 of the tone-arm is mounted a stirrup 13, which stirrup is connected to the wall of the tone-- arm support on one side, at 14, at a point higher up, that is, in a higher horizontal plane, than is the other side 15 of the stirrup, and acoiled spring 16 is connected at its lower end to the bottom of said stirrup and at its upper end to the pin 10, in the axis of support 8. The higher end '14 of said stirrup is in a position to be engaged by the lower edge of the spherical portion .of the tone-arm when the latter is swun to one side of the record and the soundox end thereof released, thereby limiting the downward tilting or rocking action of the tone-arm and acting as a support or stop to hold the tone-arm in an approximately hori-. zontal position. On the other hand, the lower portion 15 of the stirrup is in a position where it will not be engaged by the lower edge of the spherical portion of the tone-arm when the tone-arm is considerably elevated. At the same time, the point where the spring 16 is connected with the stirrup is sufiiciently removed .from the point where said spring is connected to the pin 10 to afford the necessary yielding action and yet the spring 16.

It will be observed therefore, that this invention provides an extremely simple, cheaply manufactured tone-arm and support therefor, while providing efficiently for all of the movements incident to the perfect. operation of the tone arm. Furthermore,-

while the invention has been illustrated as od ed ll 1 1. 91 of talking mach ne flaring outwardly from wherein the sound amplifier is enclosed Within a casing below the plane of the record- 1.
