this art. As the specific construction of the recorder-rcproducer and of the feeding mechanism therefor constitutes no part of my present invention, the details are not illustrated.

in the construction shown the mandrel is driven by means of a wheel 5 which is loose on the mandrel shaft but which can be operatively connected therewith by means ofv a jaw clutch 6. This clutch can be thrown into and out of operation in any of the well known ways, it being preferably opened and closed manually. For rotating the wheel 5 a suitable motor is pro\"ided,-

this motor in the preferred construction being an electric motor as indicated at 7 in the drawings. This motor is connected with the wheel. by a suitable power transmitting device such as the leather belt 8.

The motor is provided with. a suitable device for starting and stopping it, and in the case. of an electric motor, such as here shown, the starting and stopping device is a. suitable switch. f

Connected with the recr rder-reproduc preferably by means of a. long flexible tutti 5) is a mouth-piece 10 into which the dictator talks. This mouth-piece is movable vertically with respect to thc recorder-reproduced and a suitable support for it is provided for holding it in a definite predetermined inopcrativc position. In accordance with my invention this support for the uuiuth-piece is mechanically connected \vithtlie start and stop mechanism for the r motor, in this case the switch, so that the motor is started when the mouth-pie is removed from its support am. stopped when the mouthpiece is returned to its support.

In the construction illust 'ated use made of the horizontal bar 1iv which provided on dictaphones for carrying the scale which. indicates the position of the recorder-reprmlucer. Secured to this bar is 12 having a recess with walls adapted to fit the top and side surfaces of the bar. Extending through. the bottom of the bracket is a set screw 13 adapted. to engage the inner side of the bar and lock the bracket in place.

The bracket 12 is provided with two pairs of cars leis-ll and l515- between which extends a hook lever 16. This hook lever is preferably formed of" sheet metal doubled its upper end to the rear the sake of convenience and simplicity, this switch 19 is secured to an arm 20 formed integrally with the bracket 12. The switch can be of any suitable construction but I prefer a switch having a cylindrical casing and having 'a plunger working therein. Suitable contacts are carried by the casing and the plunger so that the circuit is completed when the plunger is in its lower position and broken when the plunger is in its upper position. Suitable electrical connectrons are provided between the switch 19 and the motor 7, these not being shown in detail as they will be obvious to those familiar with electrical constructions.

For operating the plunger of the switch 19, I provide a link 21 pivotally connected at its lower end to the plunger and pivotally connected at its upper end to the hook lever 16, as indicated at 22. Connected to thehook lever 16 is a spring 23 which tends to throwthe rear end of the lever downward, thus throwing the switch into its circuit making position. Preferably this spring is a coil tension spring connected at part of the lever and at its lower end to the arm 20. The

3 spring 23 is of such strength as to throw ished dictating,

the switch into operative position when the weight of the mouthpiece and speaking tube is not carried by theforward end of the lever. But when the mouth-piece is carried by the forward hooked end of the lever, the tension of thespri'ng 23 is overcome and the switch 19 is opened. Preferably there is provided a set screw which extends upward between the two ears 15l5 of the bracket and serves a stop to limit the downward movement of the lever 16, thus preventing the transmission totheswitch of the weight of the mouth-piece and speaking tube. This set screw is indicated in the drawing by 21 and it is preferably adjustable.

From the foregoing description, it will be understood that the user of the talking machine need give no attention to the motor. Vhen he desires to dictate it is only necessary for him to pick up the speaking tube and start talking. When he has finit is only necessary for him to hang up the mouth-piece and speaking tube and the motor automatically stops. It will of course be understood that the opera- I sold as a tor may, and preferably does, make use 01 the mechanical clutch 6 above referred to for stopping and starting the mandrel and 'the record independently of the motor when he desires to stop dictating for a moment only.

The switch and the pivoted mouth-piece supporting lever connected therewith, together with the supporting bracket and other parts illustrated in the drawing are well adapted to be made and sold independently of the other parts of the talking machine, and are capable of being applied to talking machines already in thehands of users and not originally provided with an automatic start and stop mechanism embodying my invention. My invention is therefore to be understood a mechanism whether manufactured and sold separately or whethermanufactured and part of a complete talking machine.
