Moons, m, or HAGERSTOWN, MARYLAND, ASSIGINOR 'ro DnoA-ni'sc PHONOGBAIPH COMPANY, 01* WAYNESBORO, PENNSYLVANIA, A CORPORATION .REMOTE CONTROL FOR TALKING MACHINES Application filed December 22, 1927, Serial No. 24:1,931.

My invention relates to control devices and more particularly to mechanism for controlling: the operation of automatic talking machines", the said-controlling mechanism being placed at a distance from the operating mechanism for the talking machines.

It is an object of the invention to provide a control device of this character in which the cabinet containing the records and the operatin g mechanism may be located in one'place and a soundprodi'icing unit having-associated therewith control mechanism may be positioned inanother place.

The invention is an'impr'oveme-nt over the machine shown and described in my copendirrg a plication, Serial No; 1683674, filed Februa ry 16; 1927, for automatic talking machines. The improvement consists lll'plOVlfiling'the talking machine presentedin said'applicat'ion with areproducingiunit which may be positioned at a distance from the 1 cabinet containing the records and thebperating .7 mechanism for playing them anc. providing means for controlling the operating mechanism at or near the reproducing unit.

The mechanism for rotating the record table for changing records is the same as-that shown in the application above referred to. This invention; however, is provided with aae'lectrical pick-up which transmits impulses to anau'iplifi cr from which they are transmitted to a loud s'pea kingunit and reproduced in a manner well known to -tli'e n'iusical world.

Referring to the accompanying drawings which are made apart hereof and on which similar reference characters indicate similar parts;

current.

Referring now to Fig. 5, wherein is shown a diagrammatic view of'the wiring constituting the controlmechanism and the operating mechanism of the cabinet, numeral 16 indicates a record table for supporting the record to be played and 17 the tone arm carrying a tone box 18. The tone box in this application is in the nature of atelephone transmitting unit for transmitting impulses through wires 19' and 20 to an amplifying unit 21. lVires 22 and 23 lead from the amplifying unit to a loud speaker unit at in the loud speaker 12. A resistance element 25 is connected across the wires 22 and 23 to provide a volume control for the loud speaker.

Since the method oi transmitting sound waves and reproducing them at a distance by means of a loud speaker is well known "further description is believed uimeccssary.

The mechanism for changing records and for setting in motion the record changing mechanism is the same as that shown and described in the application above referred to and will be described here only in suiiicient outline to furnish an understanding of the control mechanism representing the subject matter of-this application.

Numeral 26 indicates the motor for driving the record changing mechanism on the phonograph. This motor is operated by currenttaken from wires 27' and 28 connectedlo suitable source of current as, for example lead in wires 29 and 30. lVire 31 connects the wire 28 through switch elements 32 and 33. These switches are normally open but when either one or both is closed current is fed to the motor 26 to operate the record changing mechanism; The switch 32 is operated by the tone arm 17 as it swings into the center of I the record upon completion of the playing Y of the record. Since the switch 32 is closed only for a short time switch 33 is closedby suitable mechanism to continue operation of the record changing mechanism until the record has been, changed and the whole machine restored record. 1 /Vires 34 and '35 connect wires 31 and 28 at 36 and 37 respectively. Wires 34 and 3 5 lead to a switch 38 on-th'e control mechanism 13. This switch-38 is normally open. it

ymay be closed, however, to provide means 'ing the record. .othcr side of this motor. A wire 50 is conind ependent of the tone arm for. operating the record changing mechanism as shown and described in the copendin-g application referred to. A wire 39 connected to lead in-wire 29 at'40 leads to a point 41 on a double throw switch having forks 43 and 44. Wire45 is connected at 46 to an arm47 with which the fork 44 on the double. throw switch makes contact in oneof its positions. The wire 45 also connects to one side of a motor 48 at 49.

This motor rotates the record table for play- The wire 28 connects the arm 62 with which the fork 43 of the double throw switch makes contact in" one of "its positions. Awire 63 isjoined to wire 66 at 64 and leads to a post 65 on a switch element 66. A wire 67 connected to post 46 joins the switch element 68 at 69. The contact points 96 on the members 66 and 68 are normally in contact during the playing of'a record.

The switch 56 is normally open. This switch, however, is closed momentarily with each change of a record to energize the solenoid 59 for a purpose which will later appear. A circuit breaker 7.1 may be positioned in th line 27 to interrupt the current to the motor in case the record changing mechanism should become jammed. For operating this circuit breaker, I preferably use the device shown in my copending application, Serial No. 218,301, filed September 8, 1927, for automatic circuit breakers. 1

As shown in Figs. 3 and 4, a ratchet wheel 7 2 provides means for playing continuously a predetermined number of'records. In the application above referred to this ratchet wheel or escapement means is operated by movement of therecord table. In the invention herein presented I operate this escape ment mechanism by the solenoid 59 which, as i above stated, isenergized at the end of each record that is played. The solenoid 59 pulls to position to play the next down on the arm 7 3 which-allows a spring to rotate the escapement mechanism through one notch A manually operated handle 7 4 is pivoted in the front plate of the control mechanism and has an arm adapted to engage the escapement pawl 3. Oscillation of thepin 74 will release the pawl 73 sons to allow rotation ofthe escapeinent wheel. This provides means for manually rotating the escapementwheel.

Pivoted in the front plate of the control j mechanism 1s a lever 7 6 having a roller 77 of insulating material. This roller engages the outer curved ends of the members 43 and 44 on the switch 42. As shown in Fig. 3, the lever 76 is in the neutral position. "When the lever 7 6 is turned to theright, the roller 7 7 will press against arm 44 and make contact with the arm'47. When the lever is moved to the'left. contact will be made be- I records in the cabinet of the machine.

When the lever 7 6 is turned to the right, so as to make contact between members 44 and 47, current may pass from the lead in wire '29 through the wire 39 to contact point 41, through arm 44, arm '47,. thr0ugh wires 45 and 50 to the motor which operates the record table and to the amplifier respectively. It is immaterial whether the switch points 90 are in contact or not since the current does not have to pass through them. When, however, the lever 76 is moved to the left, current passes from lead in 29 through wire 39 to contact point 41, through arm 43, arm 62, through wire 63, through switch arms 66 and 68, through contact points 90, through wires 67 and through wires45 and 50 to the motor '48 and amplifier 21 to rotate the record table ing mechanism is positioned in some remote placeout of the way. The control element 13 carrying all the necessary controlling mechs5 tween arm 62 and member 43 onthe switch.

the sound vibrations on therecord are picked In witness whereof, I have hereunto set my up by the needle and transmitted through hand at WVaynesboro, Pennsylvania, this the transmitting element 18 to the amplifier 17th day of December, A.

electrical pick-up is well known. The record changing mechanism and the automatic movementsof the tone arm and the record table which cause operation of the record changing motor are shown and described in the application above referred to and form no part of this application. But in this application the means for controlling the operation of these devices are placed on the control unit 13. As shown, these controlling devices consist of lever 7 6 which when in neutral position will hold the operating mechanism in inoperative position but when moved either to the right or to the left will cause continuous playing of the records on the machine or will play a predetermined number of records. The plunger 7 8 provides means for rejectingany record before it has been completely played. The knob 79 provides volume control for the loud speaker.

It will be seen, therefore, that I have provided means remotely positioned from the record cabinet and the operating mechanism for cont-rolling the playing of the records.

Theloud speaker unit and the control unit may be housed in an attractive small cabinet which may be placed on a desk, or mantel, or a table, or may be readily moved from place to place with ease.

It will be obvious to those skilled in the 'art that various changes may be made in my device without departing from the spirit of the invention, and I, therefore, do not limit myself to what is shown in the drawings and described in the specification, but only as set forth in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. A talking machine comprising two units, one comprising a cabinet containing the records and operating mechanism therefor including an electric pick-up device and an amplifier, and the other adapted to contain a speaking unit and mechanism for controlling the operating mechanism in the firstnamed cabinet, the unit containing the speaking and the controlling mechanism being positioned remotely from the operating mechanism, substantially as set forth.

2. In a talking machine having a cabinet containing a plurality of records, mechanism for playing the same successively, an electric pick-up device and an amplifier, a second cabinet containing a loud speaking unit and controlling mechanism for the operating mechanism in the first-named cabinet, and operative connections between the two cabinets whereby they may be remotely posi- WILLIAM R.
