TALKING-MACHINE.

Specification of Letters Patent.

Patented Get. 17. 191 i;

Application filed December 3, 1906. Serial No. 346,026.

To all whom it may concern:

Be it known that I, WALTER H. Polo runny, a citizen of the United States, resid ing .at New York city, borough of Mom .5 huttan, in the county and State of New York,

have invented certain new and useful linprove nents in Talking-Machines, oil" which the following is a specification.

My invention relates generally to talking n'istically controlling the rotating table or support which carries the record.

Tho object of the invention is to do away with the hand-operated brake new commonly employed. in talking machines and cause the rotation of the record supporting table to be automatically controlled by the sound-box or reproducer, which, in being lowered into engagement with the record or swung upward clear of the seine, aotuetes it suitable brake device in e manner to limit thQ l'otation eof the record supporting table to periods When the reprodueer is in contact with the record.

irfurther object is to utilize the brake {LS inc-inns of yicldingly supporting the soundz in. the position it usually occupies shove clear of the record when the machine is not in operation or while one record is being sostituted for another.

Mechanism suitable for curryi 4 my inion into eilect is illustrated in the acing drawings. i do not wish to be is cod, howeyer, as limiting myself "to the exact Hl'fi or arm. hown, as r; ions clmng ther in without dopurti -.1 and sipe of my invention.

fie rhwm ings-l igure 1 is a side clepurily in section, of talking me. o well known type, showing my Fig. 2 is ndoteil. cross only be from the a. detail section on the line e, s", and Fig. 5 is a like new on the l 3 of Fig. l.

' ierring now to, the drawings, '1. repre-.

sents the casing of the nuichine, the retating table on which the record 3 is supported, 4- a bracket secured to the casing and provided with n vertically disposed sleevelike ofi' set 5, to receive the small end of the horn 6 ,andlthe shaped end of, the tapered arm or sound. conveying tube 7 The sleeve machines and particularly to means for auto seen that us the sound-Mix is slotted upon opposite sides as indicated at S and projecting into the slots, there are oppositely disposed screws or studs 9,3vhieh serve to secure the tapererin in position and support the some free to swing vertically and horizontally. At the outer end of the arm 7, n. sound-box 10 is mounted in the usual manner to cooperate with the record carried by the rotating table above refe red to, the arm 7 and sound-box 10 forming the reprorilucer. t i The construction thus far described is that found in machines now in general use and forms no part of tile present invention, being here employed for purposes of illustro. tio'n only and it will he understood that the invention is not limited in its use to the particular type of machine shown.

Pivotelly mounted upon a. cross pin ll of the bracket 4, there is a hrnkenrin 12, the free end of whieh is recessed to receive a. piece of felt or other material suitable for tricrionelly engaging the edge of the rotat-- ing table.

Under the notion of twin springs 1.3, orrnnged one on each sideofthe arm 12, as shown in i ig. 3, the brake yicldingly held llher in or out of engagement \Yllll the table. The springs are secured at their owor ends ton cross pin i l, fixed directly elow the piyot pin and have their upper c;.ds hooked over uds l1) ot the lu'ukcnrni, the arrangement being such, that as the brake-arm moved for enough in either allrection toirnrry the studs over the pivotal center, the springs not to contimic the movemontnand snup the brake forward into on gogcinont with the table or backward against a stop 16, depending u mntho direction of the initial l'i'lUYQlllOiiil iuipmrted to the some.

The brake connected i'h ough a link 17, hell-crunk l5 and pin 1?), to the elbow of the taper arm and tlu'is :urruu bl, it will he tilled i'roo'i the record, motion will he in'iported through the coiuiei'ztion. described, to the brake-uric, giving it movement :l'orwar d toward the table until the studs 15 pass over the pivotnl center 14 and thereupon, the springs not to complete the movement and yieldingly maintain the brake applied.

It will be observed, that when the brake is thrown on as just described, the return of the sound-hox is opposed by the brake springs and as a. result, the sound-bcx is vieldingly held by the same in an elevated rotation of the support.

locking device such as is ordinarily employed for this purpose.

To throw off the brake, it is only necessary to move the sound-box downward toward the record and the required motion will be imparted to cause the brake-arm to swing away from the table until the springs act to force it back against the stop.

A pin and slot connection indicated at 20, is preferably employed between the bellcrank and the link 17, in order to produce sutlicient lost motion to enable the brake to be thrown on or oli' at any desired point in the vertical movement of the sound-box.

The pin 19 is connected to the taper arm by a universal joint indicated at 21, which permits the arm to mo've freely both vertically and horizontally as required.

In adapting the device to other types of talking machines, the connection between the taper arm and the brake may be changed in any manner desired or the brake may be arranged to cooperate with some member of the motor other than the rotating table or other changes may be made in the construction shown within the meaning of the present invention, the essential feature of which is the automatic control of the brake by the sound-box, the resulting advantages of which will be apparent from the foregoing description.

Having. therefore, described my invention, I claim:

1. In a talking machine, the combination of a rotatable support for a record, a soundbox mounted in operative relation thereto, a brake cooperating with the record support, and a connection through which motion of the sound-box in planes at right angles to the surface of the record is transmitted to the brake.
