Fig. 7. shows 55 the'method employed for engaging the knob shaft 32 with the selector switch shaft 33. The same construction is employed for engaging the volume control knob shaft with the shaft of the volume control 3. When the cover I is'applied to the device', as shown in Fig. 4, the pin 3l, Fig. 6, in each knob shaft engages withl the corresponding slots in the selector and volume control shafts respectively,

A detachable fabric coin receiving bag I3 is suspended by two studs I4.

Lamps I5 are arranged to illuminate the printed program slips attached to the program plate assembly 5Fig. 1. v

The -loud speaker I5, Figs. 4 and 5, is attached to the back plate in a ponsition to correspond with the hole in the baille of. the cover I. A terminal strip I1, Fig. 4, is provided as a junction to which are attached the control cable wires from the selective sound reproducer. Y

When a coin is deposited through the metering plate I3, it falls by the action of gravity through coin receiver 3 and impinges upon petal I 3, which momentarily closes switch 20, Fig. 4. After closing the momentaryswitch 2li the coin falls into and is retained by bag I3.

Utilizing well known means, spurious coins are deflected and by-passed over petal I3 directly into the money bag I3, thus avoiding the closing of the momentary switch 23.

Referring to Fig. 5, the cover I is removed from the A back plate 1 by unscrewing cylinder lock 2 which permits the cover to be drawn forward and downwardly releasing it from the dowel pins 2I which are anchored in the back plate, Figs. 1 and 5.

.The program assembly 3, Fig. 5, is mounted behind glass window 22 and is slotted for the passage and diffusion of light. Thus the printed strips 23, which are attached to the inclined portions of the program plate, are illuminated by lampsA Il.A

Spring clips 24. are provided to retain the program plate assembly in its proper position and also provide means for quickly detaching the assembly to facilitate the changing of the printed program slips. v l

The loud speaker I3, Fig. 5, is shown positioned behind the circular baille plate and air seal 25 directly'to the rear of the wire cloth grille 3.

The volume control 3, shown in Fig. 4, is a conventional variable resistance L pad shown inthe circuit diagram and its action will behereinafter described.

The selector switch III, shown in section in Fig. 6, is an insulated multi-contact unit provided with a detent 23. fl'he'contact arm, 21, which carries an ordinary brush mer'nber, is held into contact with any one of radial contacts 23 by the detent action of the ball 23 resting in radial depressions in a plate 23, which depressions correspond in number. to the contacts 23. The slotted shaft 33 is shown in engagement with a' pin'which is integralwith the collar 32 and the knob shaft 33. l

Referring to Figs. 5 and v'1, a locking arm 34 is provided to prevent normal rotation of the control knob. The arm 34 is integral with the knob shaft 33, shown in Fig. 6, and has studs 3| attachedto the ends thereof for normal engagement with a` fixed metering plate 33, shown in Figs. 5 and -'1, which plate is affixed to the inside of the cover I.

The spring 31 between the casing and the control knob, Figs. 5 and 6, normally urges the locking arm pins 3| into engagement with the holes in locking plate 33, thus normally preventing the rotation of the knob.

When the selector knob is pushed inwardly the locking arm 34 is disengaged from the plate 33 and rotation may be imparted to the selector switch. Simultaneously the breaker switch 33,

Fig. 6, is opened through the action of collar 32 depressing the insulator which is attached to the inner switch spring 39. l

In actual operation the operator chooses a selection from the program plate 5, Fig. 1, and then depresses the control knob 3 inwardly and turns the knob pointer II to a number, on the selector plate as shown, corresponding to the selection desired. While the knob is depressed, yswitch 33-39 is opened and the locking arm 34 of the lselector switch is-free to rotate. When the knob is released the locking arm 34 reengages plate 36 vand prevents further rotation and simultaneously the switch 33 is closed.-

A coin may then be deposited in the coin receiver plate I3 and the weight of the coin depresses petal I9 closing the contacts 23 momentarily whichl completes a circuit to the selective sound reproducer through breaker switch 33-33, switch contact arm 21 and a corresponding contact 23. j.

Since it is necessary to move the selector knob to disengagethe locking arm 34 from thev plate 36, which causes the switch 38-39 to open, an

operator is prevented from obtaining more than one selection upon the deposit of a single nickel,

which wouldb the case if the above means were ,erator by means of the control knob. 4 which rotates the L pad 3.

Fig. 2 shows a diagrammatic lay-out of a typical installation with a selective sound reproducer at A and selective remote control devices in separate enclosures at a, b, c. d,` and e. The dotted lines `connecting the above devices to the sound reproducer represent multiple cables and are equivalent to the conductors 46 in Fig. 3. The wiring diagram, Fig. 3, shows the circuit employed in connecting one remote controller device to a selective sound reproducer. When more than one remote controller device is used the conductors are connected in parallel.

Alternating -current power is supplied to the remote controller by transformer 43, one terminal of the secondary of which is connected to the common line 4I of the selectiveA reproducer and the other'terminal connected to one side of the momentary switch 20. The opposite side of the momentary switch is connected to the rotary arm 21 of the selector switch through manual breaker switch 33; thus when the selector knob is' pushed inwardly' the arm 21 can bemoved to a desired contact'23, the breaker switch preventing the completion of the circuit, and by releasing the selector knob, a circuit may be established through the closed breaker switch and the momentary switch 23 by the deposit of a coin.

lSince the selective reproducer A is presumed I inwardly, as previously described, may rotate the selector switch arm 21 until it rests upon the contact selected, in this case indicated by numeral 28. It will be observed that while the operator is rotating the switch arm 2l he has necessarily moved the control knob inwardly, which opens the switch 3B-39.' Upon releasing the control knob the switch 38-39 is closed by the action of a 'spring previously described. I

Then, upon the deposit of an appropriate coin in the coin receiver, the switch 2l is momentarily closed, which completes a circuit as follows: From one side of the secondary of the power supply transformer 40, through themomentary switch 20, through the breaker switch 28-39, through thevswitch arm 21 and selected contact 28', from contact 28 through a conductor to a corresponding electro-magnet 45 in the selective sound reproducer, through conductor 48.

Since one side of all the magnets 45 in the sound reproducer are common, the circuit is completed througha conductor to terminal 4| and return to the remaining side of the secondary ,of the power transformer. Y
