3 Claims. (Cl. 179-63) This invention relates to coin controlledrecord apparatus.

An object of this invention is to provide an improved record playing system wherein a coin box and a loudspeaker may be disposed at one location and electrically connected to a central station, wherein the records selected at the coin box are played and'then the sound is transmitted back to the loudspeaker.

Another object of this invention is to provide a central record playing station wherein a plurality of'record playing members are located with each'recordplaying member having a preselected record thereon and the record playing member is actuated through dropping of a coin at a remote point.

A'furtherobject of this invention is to provide an improved record transmitting system which operates on the principle of telephone dials so that the person dropping the coin in the coin box may dial a/code character or number and when the dialing has been completed the selected record will be played and the soundtransmitted back to the location of the coin box ,for audio transmission through a loudspeaker. With a system of this kind the servicing of the record playing members is simplified and the usual automatic record playing devices .at present positioned in different locations will be eliminated.

To the foregoing objects, and others which mayhereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings: g

Figure 1 is a diametrical view of a record playing system constructed according to an embodiment of this invention, 7

Figure 2 is a fragmentary frontelevation of the coin box, r

Figure 3 is a schematic view of the electric circuits embodied in this invention,

Figure 4 is a schematic view of the pre-amplifier, and

Figure 5 is a schematic view of the power supply for the selector.

Referring to the drawing, the numeral l0 designates generally a relay exchange of the type at present in use in automatic or dial telephone systems. 1 The relay means I0 is connected by means of a conductor 1 l to a remotely disposedcoin controlled selector box l2. The selector box l2 includes a dial l3 of the typeat present in' use on dial telephones. The selector member [2 is also connected by means-oi a conductor [4 to aground or return conductor, so as to provide the complete circuit to the relay" means Ill. The selector member I2 has positioned on the outer face thereof the titles l5 of records which it is desired to have played and each title l5 has associated therewith code characters or numerals l6 which are similar to the characters and numerals at present appearing on dial telephones and there may be any desired number of these characters or numerals.

A loudspeaker IT .is positioned at the same location as the selector [2 and is electrically connectedby means of a wire 18 to the relay means in and by means of a'wire [9 to the ground or return. The relay means H), which is positioned at the central location or station; has connected thereto a plurality of record playing members,

generally designated as 20. Each record playing member 20 includes a-motor 2| having a turn table 22 operated thereby and on which a'record is adapted to be positioned. .A tone or needle carrying arm 23 isadapted to engage the record on the table 22 and'is connected by means of conductors24 and 25 tofthe' relay means in and to the loudspeaker [1. The relay means In is of such construction that'when the dial I3 is turned in accordance with the codecharacters l6 a circuit will be completed to a preselected motor 2| and to the tone ar'mor transmitter 23, so that the sound picked up by the tone arm 23 will be transmitted back to the location through the conductors l8and Hi to the loudspeaker.

As shown in Figure 3 the central location is provided with a plurality of record playing devices 20 which are connected to the selector I3. The record playing devices 20 each includes a motor 2| connected at one side, as at. 26, to a source of current supply and connected at the other side. by means of a conductor '21 toa relay operated switch 28, which is normally biased to an open or circuit breaking position. A relay. 29

actuates the switch 28 for moving the latter tov closed position having one side 30 connected to the ground and the other side 3| connected to one of a series of contacts 32 arranged in a circle which are wiped by a wiper 33 carried by an arm 34. The arm 34 is fixed to and insulated from a shaft 35. There will be a relay 29 and a switch 28 for each record playing motor and each relay will be connected to one of the contacts 32. The tone arm 23 which engages the record on the "circuit 'breaking 'positionand moved to" a table 22 when the latter is elevated by conventional elevating means and tone arm 23 is connected by means of a pair of conductors 24 and 25 to a pre-amplifier, generally designated as 36. The pre-amplifier 36 embodies a pair of amplifying tubes 31 and 38, shown in Figure 4, which are connected to a power transformer39 of conventional construction having a suitable plug connector as shown. j

One side 4!! of the output side ofthe-pre-amplifier 36 is connected by" means of a fconductor 40 to one end of a primary transformer 4|. The

other end of the primary 4| is connected by con-1J1 ductor 42 to a wiper carrying arm 43, @150 mounted the other side of the output of the. pre-amplifr'ier 36.

The ratchet 83 is mounted on the shaft so that upon movement of the lever 8| the shaft 35 will be rotated step by step according to the number selected and dialed on the dial I3. The conductor 54 is connected to the secondary 85 of the transformer 86 and a condenser 81 is interposed in the conductor 54 adjacent one end of the secondary 85. The other end of the secondary isconnected-by the conductor I 4 to the ground ahda condenser 88 is intrp o'sed in the conductor 14. The conductor I I is connected to the conductor 54 and is also connected to a resilient concounter-clo'ckwis 2.

The flow of current in-the primary winding M, will induce a'pulsating current in 'the secondary windingflflfi, which current will flow through the conductor lfl; thecontact 89', "thefcontact 92, to the 'conductor 93 andhence to the amplifier" at the receiving station." i J When the record has been completely played, the turntable 22 will move to reset position and will depress the contact 64 against contact 66. Current will then flow from the power supply 39, through the conductor 34, the connectors 56 and the contacts 55 and 58 into the arm 51 and through the conductor 59 to the closed contacts 60 and 62. From the latter current will flow through the conductor 63, the closed contacts 64 and 66, the conductor 61, and the closedycontacts 69 and 'IIto the conductor I2 which connects to the contact I3 of the normally closed switch 14. From the contact I5 of the switch I4, the current will flow through the coil I6 to ground, thereby energizing the coil and moving the core TI and the pawl 82. Such movement of the core 1! will also efiect the opening of switch I4 so that the pawl 82 will be reciprocated, thus rotating the shaft 35. This step-by-step rotation of the shaft will continue until the arm 51 is positioned as shown in Figure 3, that is, with the contact 58 disengaged from the contacts 55 in tacts II and 60 respectively. The selector willthen be in position for the selection of a turntable as,,-described above by dialing at I3.

The power supply for the selector includes, as shown in Figure 5, a rectifier IUI of conventional construction connected to the secondary I02 of a power transformer I03. The output of the rectifier II is connected by conductors I04 and I05 to an outlet connector I86. A fuse Ill! is interposed in one of the conductors between the rectifier IOI and the secondary I92 and a fuse ms is interposed in one of the power lines leading to the primary I09 of the transformer I03 and having a suitable plug connector as shown. The conductor I04 is grounded, as indicated at III and a connector III which engages the connector I06 has one terminal thereof grounded by a conductor I I2 and the others connected to conductors 84 and 48. Contact 98 of switch 96 is connected to the main amplifier (not shown) on one side of the circuit of the amplifier, and wire 93 is also connected to the main amplifier. The connection of the contact 98 with the main amplifier is for the purpose of obtaining a relatively low voltage current to relay 52, whereby when the dialing operation has been completed and pin 90 is at rest, the switch formed by the contacts 89 and 92 will be closed to wire 93 to supply a current of higher voltage.
