Patented June 3, 1919.

Application filed-December 27, 1917. Serial No. 209,112.

To all whom t may concern.'

' B'e it known that I, FRANCISCO MNDEZ GIL, a citizen of the Republic of Mexico, and

a resident of city of Mexico, Mexico, have invented certain newanduseful Improvements in Phonographic Clocks, of which the following is a' full and clear specification.

The object of this invention is to provide Va simple reliable electro-mechanical mechanism for periodically operating a talking machine through the medium of a clock or other time-piece, whereby, at desired intervals, the operation of the clock will cause an automatic operation of the talking machine to announce the hour or fractions of the hour and also, either in addition thereto or separately, make other announcements, such as advertisements, as more fully hereinafter set forth.

In the drawing- Figure l is a view,partly in diagram and partly in section, showing one preferred wirincr system;

2Fig. 2 is a detail view, enlarged, showing one type of wiping contacts that may be employed for closing the local circuit of the motor-circuit and circuit-closer; and

Fig. 3 is a View similar to Fig. 2 showing another type of Contact.

In the drawing, the numeral l indicates a wheel which is geared to or otherwise connected to the clock mechanism, so as to make a complete rotation in any given period of time, say, one minute. In the periphery of :this wheel is formed a series of notches or indentations a, preferably four in number, each notch having an abrupt edge which faces in the direction opposite -t o the direction of rotation of the wheel, the direction of rotation of the wheel being indicated by an arrow, while its other ed e or face curves into the periphery of the wheel. and thus forms a cam-like surface.

Above the center of rotation of the Wheel 45 1, on a pivot 3, is mounted a lever 2 which at one side of the pivot lcarries a depending finger 4 which normally rests on the periphery of the wheel l and which at the other side of the pivot .3 carries a contact 5 which I0 is adapted to contact with a screw-contact 6.

At the end of this lever, opposite the contact 5, is a yielding contact which is adapted to make contact with a contact 33, which contact is mounted on a rod 37 which is adapted to be vertically adjusted by a setscrew 30, which contact 33 is normally drawn toward contact' 20 by a spring 33. Also carried by the lever 2 is an arm 4 which isv preferably an extension of the finger 4 and carries on its extreme end a piece of insulating material 4 in such position as to engage under the spring-contact 3.3 and lift the same of contact 20 when the lever 2 is tilted upwardly at that end. The contact arm 33 is prevented from being pulled down below its normal position by a lug 33 carried at the upper end of rod 37.

rIhe contact 6 is mounted upon a screwbolt 34 which works through a `post 34 and is provided with a thumb-nut 25, whereby contact 6 may be adjusted with respect to contact 5.. The contacts 5 and 6 are included in a circuit 35, in which is a battery 35 and an electro-magnet 8. When this circuit 35 is closed by the contacts 5 and 6 coming together, the magnet 8 is energized and attracts its armature 11. This movement of the armature l1 brings contacts 10 and l2 together and thus closes a motor circuit 39-40, in which the motor 15 is included, this circuit obtaining its current from a main or a local source 'of sufficient electro-motive force to operate the motor 15. This motor l5 is connected by a beltv 17 to the operatingwheel of the phonograph 16.

Adjacent the phonograph is located av magnet 18 Whose armature is provided' with a brake-shoe 19, which, when the armature is attracted, presses on the belt 17-and thus, gy a braking action stops the phonograph.

his magnet 1,8 is in a circuit 38, one branch of which is electrically connected to contact 33 and the other branch of which is cony nected toa binding post 14 which carries an adjustable screw 14 positioned so as to make contact with a contact 11 on the armature 11 when magnet 8 is denergized.

It will be observed' that when the finger 4 drops into one of the notches in the wheel 1, the contacts 5 and 6 will be closed, thereby, as above set forth, closing the motor circuit and bringing aboutthe operation of the phonograph. As the wheel 1 rotates, the left end of lever 2 will be tilted upwardly and thus break contact with 5 and( 6, thereby cutting off the current from the motor. he parts are so adjusted that the instant after the motor is cut out, the lcontact 20 will Contact with part 33 and thus close circuit 36-88 of the magnet 18, whereupon brake-shoe 19 will. be applied to the phonograph and thus stop the same. As the wheel 1 continues to rotate and thus further tilt the left end of lever 2 upwardly, the arm 4 will cause a separation of contacts'20 and 33v and thus break circuit 38, thereby releasing brake 19, thereby leaving the talking machine ready to be again operated. -It will lbe observed that. the time during which the phonograph shall continue to run may be varied' by varying lthe adjustments atcontacts 5 and 6, the more close the adjustment -the shorter the period of operation, as is obvious.

In order to permit the usual use of the talking machine independently of the clock, I provide a switch b in the circuit 359-40, whereby said circuit may be closed manually without regard tothe clock-operated' automatic mechanism.

It will be understood that any suitable arrangement may be employed for keeping the contacts 5 and 6 in contact until the predetermined time for the separation has arrived. In Fig. 2 I show one way of doing this. In this View, contact 5 slides along on 'contact 6 until the ingerA: tilts the lever far enough to disconnect it from contact 6. It willv be observed' that by vertically adjusting contact 6, the interval of time during which the contacts are in engagement may be varied and thus vary the time of the running of the talking machine. The contact 5 is elastic so as to press against the downwardly-inclined surface of the contact 6. In the' structure shown in Fig. 3, this same result is obtained 'by employing a flat elastic contact 5 adapted to flex slightly when pressed against the point of screw contact 6 by the spring 41. v

The nature and scope of the invention having been thus indicated and its preferred end of said lever, one pair of contacts con` trolling the operation of the motor, and an electro-magnetic brake appliance controlled by the other pair of contacts.

f2. In combination, a time-piece, a talking machine, an electric motorl for operating the i talking machine, means operated by the time-piece for closing the motor circuit, said means emloodying an electro-magnetic device having a movable armature forming part of the motor circuit, a brake for the phonograph, an electro-magnetic device for operating this brake including a circuit and means for closing contacts in said circuit at one point when said armature is retracted to open the motor fcircuit, and means for closing this brake circuit at another point by operation of the time-piece.

3., In combination, a time-piece, a talking machine, an electric motor means for driving the talking machine, means operated by the time-piece for periodically opening and closing the circuit of the motor, an electric brake means for the phonograph including a circuit, and means operated from the time-piece for first closing this circuit to apply the 'brake to thus stop the phonograph after the motor-circuit is broken and then opening the 4circuit to release the brake.,

In testimony whereof I hereunto aliix my signature.

FRCO. MNDEZ GIL.
