AUTOMATIC STOP FOR TALKING-MACHINES.

To all whom it may concern:

Be it known that I, CHARLES H. SWIEGLE, residing at Spokane, in the county of Spokane and State of Washington, have invented new and useful Improvements in Automatic Stops for Talking-Machines, of which the following is a specification.

This invention relates to talking machines and has for its object the provision of means whereby upon completion of the playing of a disk record, mechanism will be actuated for stopping the motor and consequently the rotation of the turn-table and record.

An important object is the provision of means of this character including a turntable provided with a cut away portion upon which is adapted to be disposed a record of the disk type provided with a partially spiral slot formed as a continuation of the sound grooves of the record and through which the stylus is adapted to drop, the turn-table having disposed therebeneath a trip lever adapted for engagement by the stylus and connected with the brake setting mechanism for stopping rotation of the turn-table.

Another object is the provision of means ofthis character which will be simple and inexpensive in construction, eflicient and automatic in action, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illus trated in the accompanying drawing, in which- Figure 1 is a plan view of a talking machine having disposed upon the turn-table thereof a record constructed in accordance with my invention,

Fig. 2 is a plan view of the turn-table with the record removed therefrom.

Referring more particularly to the drawing, the numeral 10 designates the turn-table of a talking machine of any ordinary or preferred type. This turn-table 10 is provided with a semicircular cut-out portion 11 and has disposed therebeneath a lever 12 positioned beneath the cut-out portion 11 and connected by means 13 with the brake setting lever 14 for stopping the rotation of the turn-table.

Adapted for use in connection with a phonograph having its turn-table constructed as above described, is a disk 15 Patented Feb. 10, 1920.

over the cut-out portion 11 in the turn-table when in playing position,

In the operation of the devcie it will be seen that when the disk record 15 is placed upon the turn-table 11 with the slot 16 disposed over the cut-out portion 11, and the stylus reaches the end of the sound groove it will drop into and through the slot 16 in the record and into the cut-out portion 11 of the turn-table and will engage the lever 12 and consequently move the same for shifting the brake lever 14 to its position for stopping rotation of the turn-table.

From the foregoing description and a study of the drawing it will be apparent that I have thus provided a very simple and efficient means whereby a talking machine will be stopped automatically upon completion of the playing of a record. It will be observed that the record, if a double 011e, may be provided on both sides with slots at the inner ends of the sound grooves so that the automatic stop will be actuated, regardless of which side of the record is played.

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In combination, a talking machine turn-table provided adjacent its center with a cut-out portion, alever disposed beneath the turn-table and operatively connected with the brake lever of the talking machine, said first named lever projecting beneath said cut-out portion, and a record provided at the inner end of its sound groove with a partially spiral slot adapted to be arranged above said cut-out portion of the turn-table, whereby the stylus of the talking machine will, upon reaching-said slot, pass therethrough and engage said lever whereby to apply the brake.

2. In combination with the turn-table of a talking machine, said turn-table being provided adjacent its center with an opening, a lever projecting partially across said opening and operatively connected with the brake lever of the talking machine, and a record provided adjacent its center with a slot formed as a continuation of the inner end of the sound groove of the record, said slot being adapted to register with the cutout portion of said turn-table whereby upon reaching the end of the sound groove the stylus of the talking machine Will drop through said slot and said cut-out portion and will engage said lever for moving the brake lever to its potential position.

8. In combination, a talking machine turn-table provided with a cut-out portion, a lever operatively connected with the brake lever of the talking machine and disposed beneath said out out portion, and a record provided at the inner end of its sound groove with an opening adapted to be arranged above said cut out portion of the turn-table, the stylus of the talking machine entering said opening, at the completion of the playing of the record, and engaging said lever whereby to apply the brake.

In testimony whereof I afiix my signature.

CHARLES H. SlVIEGrLE.
