3 Claims.

This invention relates in general to coin actuated control devices and more particularly to control devices for an automatic selective phonograph.

ment in the present invention eliminates the rotary switch and the locking means attached thereto and the necessity for an operator to refer to numerals of an indicator plate before Setting the switch. In the present invention it is merely necessary to operate push buttons corresponding and adjacent to the titles of the program.

A principal object of the invention provides a means whereby a coin may-be deposited and a particular circuit corresponding with any one of the push buttons will be momentarily electrically energized.

Another object provides a means for preventing an operator from energizing more than one cult upon the deposit of a single coin. I

A further object provides an entirely automatic means whereby selected multiples of external circults may be momentarily energized upon alternately depositing coins and depressing the selected buttons.

Fig. l is a front external view of the casing Fig. 2 is an enlarged diagrammatic sectional view of the controller showing the essential parts of the coin actuated mechanism.

Fig. 3 shows a schematic wiring diagram portraying the coin actuated device connected with the push button switches and thence to a bank of electro magnets which represent the selective mechanism to be operated.

All of the parts except the magnets in the de- .vice to be operated are intended to be mounted within casing i, Fig. 1.

The coin aperture 2 is mounted at the top of the device and arranged to receive a coin of predetermined denomination.

Push buttons 3 are mounted adjacent to title bearing strips which comprise a program d.

Referring to the sectional view, Fig. 2; a conventional slug rejector 5 is arranged beneath the 2 in order to reject spurious coins t to the return cupl.

fall by the action of coin aperture through chute An accepted coin will gravity through chute 8 and impinge upon and depress lever B and continue to fall into the coin receiving bag or receptacle I0. I

A locking relay II is afllxed in the position shown in Fig. 2, having a pivoted armature l2' normally urged away from the core of the ma netby spring l3. I4 and pivoted'about a fixed pin IS. The lever 9 is normally urged into the position shown in full lines by spring l6. A pair of normally open electric contacts ll-|8 are operatively engagedwith a projection of cam H. A notch I9 is provided in the upper surface of the cam H for engagement with a projection IZ-a of the relay armature. Hence, when a proper coin is deposited. lever 9 will be moved downwardly, as shown in dotted lines, and the armature latch will engage the notch I9. Simultaneously the contacts I'I-l8 will be held closed.

Referring to the diagram, Fig. 3 although the device as shown in Fig. 1 contains twenty push buttons 3, for the purpose of simplicity, Fig. 3 shows only four push buttons 3 cooperating with four switches and-only five electro magnets 22 in the device to be operated. Ll-L2 represents the electric power source connected to the primary of transformer 20. One side of the secondary of the transformer is connected by conductor M to one side of all the electro magnets 22 in the device Mounted directly beneath the push button 3,

in operative relationship switches, shown in Fig. 3, 25 and 26. Switch springs closed and switch springs shown in Fig. l, and thereto, are individual comprising springs 24, 24 and 25 are normally 25 and 26 are normally open. A conductor 27 is connected to the center spring 25 of the first of the series of switches. Each rear spring 28 connects by a, separate conductor 28 to an individual magnet 22 of the series of magnets in the device to be operated. The forward spring 24 of each switch is connected to the center spring 25 of each successive switch in the series. The last switch requires no part 24.

In operation it will be apparent that when a coin is deposited the weight and momentum of the coin depresses lever 9 downwardly and the switch l'|-l8 will be closed and remain closed by virtue of the latching of the armature E2 of the relay engaging with the notch in cam It. When the operator pushes any button 3 a circuit is established through the transformer secondary,

Lever 9 is integral with cam corresponding magnet 2'2, through the relay coil H and the contacts "-48. During this instant the locking relay magnet H is energized and the armature l2 attracted to the core of the magnet against the action of spring I3, thus the cam l4 and the lever 9 are released and move to their upward position through the action of spring l8, opening the switch I'l-I8 and the common circuit to the device to be controlled.

Should an operator deposit a coin and depress two or more buttons simultaneously it is obvious that only the first button in the series will establish a momentary circuit through the device to be controlled, thus than one of the magnets 22 upon the deposit 01' a single coin.

It is also apparent that upon sequentially depositing coins and pressing selected buttons, coraforesaid arm in a displaced position,rsaid arm being adapted to be moved to its displaced position upon the deposit or a coin in said apparatus and simultaneously close the aforesaid contacts. an electric circuit connected to said electric contacts and said electro-magnet, a source of electric energy connected to said circuit, a plurality one cannot energize more .energy connected to said circuit, a plurality of auxiliary circuits connected in parallel to said circuit first named, each auxiliary circuit including a device to be operated upon the completion or the circuit first named, each auxiliary circuit having a push button switch. connected between each auxiliary circuit. and said circuit first named, means connecting said push button switches to each any one or them connects said electric energy source to one only 01' the devices to be operated, and simultaneously energizes said electro-magnet to restore said arm and first'named contacts to normal position.
