HO'KE' SIGNAL RECEIVING AND DISTRIBUTIKG SYSTEI Filed m 12, 1929 4 Sheets-Sheet 4 ATTORNEYS Patented May 12, 1931 UNITED STATES PATENT OFFICE FRANK HOKE, F INDIANAPOLIS, INDIANA, ASSIGNOR TO HOLCOMB & HOKE EANU- FACTURING COIMPANY, A. CORPORATION OF INDIANA SIGNAL ancnrv'me AND DISTRIBUTING sYsrEm Application filed August 12, 1929. Serial No. 385,435.

This invention relates to a system of distributing signals such as may be received by a radio set, telephone wires, or such as may be produced phonographically, or by several other possible methods. More particularly,

it relates to a system for installation in hotels, apartment houses, tourist camps and the like, wherein each room may be supplied with a secondary receiving device. which may be 0 connected automatically to a common receiving apparatus located in some central point.

It is contemplated. also that the connect-ion for each of the said secondary receiving devices may be controlled .by a coin or check operated time metering control whereby each receiving device is automatically connected to the main receiving apparatus for a given length of time upon the insertion of a coin of a given denomination.

In the use of the device it is contemplated that the main receiving apparatus may be .a

radio receiving set, an automatic phonograph, a television receiving set, a wire connection to some center of distribution of entertainmentor any other similar apparatus.

Correspondingly, the secondary receiving devices may be head-phones or loud speakers for the translation of electrical signals to audible signals or they may be television receivcrs for the translation of electrical sigwith the same group of secondary receiving devices. ,4 Other objects and features and the full nature of the invention will be understood from the accompanying drawings and the following description and claims:

Fig. 3 is a side elevation of portions of the interior of thesame apparatus. Fig; 4 is a rear elevational view of other portions thereof. Fig. 5 is a view of portions of the electrical control taken onthe line 55 of Fig. 4. Fig. 6 is an electrical wiring diagram ofv the connections necessary for use of the invention witha phonograph and electrical amplifier ther e-.

for and a radio receiving apparatus. Fig. 7

is a diagram of an alternative form of electrical connections for the same purpose.

Fig. 8 is a wiring diagram illustrating a I third alternative form of electrical connections for the same purpose.

In the drawings a coin time control is provided for each translating device and is indicated generally by the numeral 9.. As herein described this device is essentially the same as that disclosed in the co-pending a plication of Frank Hoke and David T. ampbell, Serial No. 381,200, filed July 26,

bottom member, 10. and a cover member 11 which forms the front, two' sides and the top ofthe box, and which is suitably locked to the member 10 and may be removed there- The control box 9 consists of a back and g Positioned within the box directly beneath the coin slot 13 is a coin receiving chute 16 of a common form including a magnet 1'? for the rejection of slugs of magnetic material, and an ejecting wheel 18 for the rejection of perforated slugs. The coin chute 16 delivers the coin 19 to the position illustrated in dotted lines in Fig. 2.

The operating handle 15 has a portion 22 bent at right angles to the handle portion and extending behind'the central plate 20. The portion 22 of the operating handle is fixedly attached to a shaft 23 pivotally mounted uponthe plate 20. A torsion spring 24 surrounds the shaft 23 and is anchored thereto at one end. The opposite end of said sprin is anchored to a pin 25 on the plate 20. The spring, therefore, serves normally to maintain the operating handle in the upper position as illustrated in Figs. 1 and 4.

Carried upon the shaft 23 and rotatable therewith are a coin engaging member 26 and an irregularly shaped member 27. The member 27 has a toothed projection 28 engaging a spring operated pawl 29. Normally, the movement of the operating handle 15 brings the toothed projection 28 in contact with the s ring pawl 29 and prevents further I motion 0 the handle. With the coin 19 in the position shown in Fig. 2, rotation of the handle 15 brings the coin engaging member 26 into contact with the coin, pressing the coin downward to contact with the pawl 29, thus removing the pawl from engagement with the tooth portion 28 and allowing further movement of the handle 15.

Carried upon themember 27 is a ratchet member 30 normally maintained in the position shown in Fig. 2 by a spring 31. The

ratchet member 30 may be moved in eitherv direction about its pivot pin 32 against the action of the spring 31. In the lowering of the operating handle 1'.- the leading corner of the ratchet member 30 engages a serrated member 33 carried upon the plate 20, thus preventing return of the operating handle. When the handle has been lowered to its lowest position, the ratchet member has traveled to the extreme end of the serrated member 33. During the return of the operatinghandle, the ratchet member 30 engages the serrated member 33 to prevent a second lowering until the said handle has again reached its normal uppermost position.

Thus, the single ratchet member, by its engagement with'the serrated member 33, insures that the operating handle, at each operation must be completely lowered before it can a ain be raised and must be completely raised efore it can again be lowered.

Carried upon the member27 is a roller 34 of insulation material; An insulation block 35 is carried upon theplate 20 and carries thereon two pairs of spring contacts 36' and 3611. When the operating handle is inits mosses Referring particularly to Fi s. 4 and 5 a clockwork mechanism indicate generally by the numeral 37 and a plurality of electric switches, herein three in number, each indicated generally by the numeral 38 are carried upon the back of the plate 20. The clockwork includesapair o fiplates 39 carrying the pivot points of the various clockwork shafts and including between them a common form of clockwork mechanism whiclrJwill not be described in detail herei n.

The portion 22 joi woperating handle 15 carries a p'ifii glW 'adapted to enga e a tooth 41 upon "a depending link 42. T e link 42 is pivotally connected at its upper end to the outer ends of a lurality of levers 43. The said levers form t e operating levers for the switches 38 and one is provided for each of said switches. Each of the switches 38 includes a metallic body portion 44 supported upon one of the plates 39 and carrying a pivot pin 45 for the corresponding operating lever 43. Carried upbn each of the metallic portions 44 is an insulating member 46 carr ing electrical connection members 47a, 47b, 4T0, 48a, 48b, and 480, as illustrated particularly in Fig. 5. Each of the levers 43 engages at its inner end an insulation piece 49, shown in Fig. 4, in turn-engaging a roller 50 of electric conducting material. Springs 51 normally maintain the said insulation pieces in contact with the said rollers. By this construction the lowering of the levers 43 by means of the handle 15 snaps one of the rollers 50 into contact with the contact members 47a and 480:, a second roller 50 into contactwith members 47 b and 48b and the third roller 50 into contact with members 47 c and 480. The raising of the said levers 43 similarly snaps the rollers into the open circuit position shown in Fi 4.

A. link 52 is pivotally connected at one end to one of the levers 43 and a tension spring 53 is likewise connected to the same lever. In the operation of the device after the insertion of the coin, the operating handle 15 is pulled down from the position shown in Fig. 4, thereby pulling down the levers 43 and snapping the switches into the close circuit position. The spring 53 is stretched by this action and thereby tends to return the levers 43 to their upper position. This tion of the link 52 with certain members of the clockwork mechanism as described in the icmpending applicationaforesai'd, until a predetermined time interval has ela sed. Upon -the completionof the said time interval the 'spring53 causes the raising of'the levers 43, thereby breaking the electric circuits. v

Referring to Fig. 6,-a wiring diagram is illustrated'showing'the invention applied for selective fuse with an automatic phonograph having an "electrical: amplifier or. with a radio receiving set. "In the diagram an autom-ati'czphonogra his-indicated generally by thenumeral 4 an is assumed to be of a type which continuously plays a series of records :1 so long as power isfsupplied to its in-put ter minals 55. Electrical'impulses corresponding to the sounds recorded upon the record are delivered by the phonograph 54 by means i 'T of the pick-up lines 56 to a conimon form of thermionicamplifier 57 The amplifier 57 is provided with" power in-put terminals 63 g and signal out-put terminals 64. In the diagram is likewise shown a radio receiving set a 58 assumed to be'of a common form having ble pole knife switch. From one of the terthelusual aerial connection 59, ground connection 60. power input terminals 61 and output terminals 62.; r For the operation of the apparatus, power is supplied from any suitable source of elec trical energy by means'of power lines 65 to a ."connecting device 66 herein shown asa doumin'als of'the knife'switch 66 a connecting line 67 leads to one of'the phonograph power input terminals a connection 68 leads to one of the power input terminals 63 of the phonograph amplifier and a third connection 69-leads to one ofthe power input terniinal 61 of the radio receiving 'set. The opposite terminal '55 'andthe. opposite terminal 63 are connected together by a connection 7 O and are connected to a terminal 71 of a double-throw, four-polekn'ife' switch 72. The opposite terminal 61 is connected by-a "conductor 73 with a terminal 74 of the knife switch 7 2; The said knifeswitch is :also provided with a terminal 75 which is connected with the terminal 74 when the said switch is thrown into the upper position as shown in -.'the diagram and is connected with terminal 71 when the said switch is thrown in the 1 lower position. The terminal 75 is connected -'by a line 76 with each of the contacts 47 0 in -'each of the coin boxes 9at the translating stations. Each of the terminals 48oin the coin boxes 9 is connected to a line 77 leading to a terminal 7 Bot the knife switch 7 2. The --.:terminal 78 is connected to a terminal 79 a when the knife switch is upwardly thrown and a terminal 80 when the knife switch is 80 are connected together by a line 81 and are also connected therebv to the opposite terminal of the knife switch 66.

By the connections just traced, it isevident that when the knife switch 66 is closed and downwardly thrown. The terminals 79 and the knifc switch 72 is u wardly thrown, the operation of any one o the coin boxes 9 to close the circuit between contact points 47 a.

and 480 will supply operating current to the radio receiver 58. Similarly if the knife switch'72 is downwardly thrown the operation of any one of the coin boxes will supply operating, current to the automatic phongraph 54 and its associated amplifier 57. The output terminals 64- of the amplifier 57 are connected by lines 82 with a pair of terminals 83 ofthe knife switch 72. The out-put terminals 62 of the radio set 58 are similarly connected to a pair of terminals 84 on the knife switch 72. When the knife switch is upwardly thrown the terminals 84 are connected to a pair of terminals 85 on the said switch. When downwardly thrown the terminals 85 and the terminals 83 are connected. One of the terminals 85-is connected by a line 86 with one oftheterminals 36 in each of the coin boxes 9. The other terminal 85 is connected by a line 87 with one of the terminals 36a in each of the coin boxes9. In each coin box the opposite terminal 36 is connected to terminal 476 and the opposite terminal 36a is connected to the terminal 47a. Each of the terminals 48a and 48b is connected to a terminal of-the speaker or headphone 88. e

By this wiring the operation of any one of the coin boxes 9 to close the connection between contact members 47 b and 48b and between contact members 47a and 48a connects the speaker 88 with the out-put terminals of the radio receiving set when the switch 72 is upwardly thrown and with the out-put terminals of the phonograph amplifier when the'switch 72 is downwardly thrown. Since electrical connection is made between members 36 and between members 36a only when the operating handle of the coin box has been returned to its normal upper position, the speaker 88 cannot be operated y manually holding the lever in its lower'position. Each dividual 'volume control rheostat 89 connected in parallel with its terminals.

' In Fig. 7 is shown an alternative form of connections in which the speakers 88 are con:

illustrated in Fig. 6. In this connection, a,

coin box 109is used difi'ering in detail but I not in principle from the coin box 9. In the box 109 the operation of the handle closes or of the speakers 88 is provided with an innected in series rather than in parallel as the box 109 is arranged to break the contact between members 470 and 480 and to make the contact between members 147 and 148 at the expiration of the predetermined time interval. In box 109 the contact elements 36 and 36a are omitted and contact elements 136 are provided. The members 136 are arranged to be out of contactwith each other when the operating handle is in its normal position. In the wiring of this device the wire 86 leading from the switch 72, as in Fig. 6, is connected by a line 186 with one terminal 136 with the terminal 147 and with one terminal of the speaker 88 of the first translating unit only. The opposite terminal of the speaker 88 is connected by a line 286 to the terminal 148 and to the opposite terminal 136. The line 286 is then connected by means of a line 86a to the second translating station in the same manner that line 86 is connected to the first translating station. Other translating stations are similarly connected in series and in the last station the line 286 leading therefrom is connected to the line 87. By this means the closing of the contact between members 147 and 148 in each translating station short circuits the speaker 88 and prevents operation thereof. The opening of the circuit of the said connection by the operation of the operating lever .permits operation of the speaker. The provision of the contact members 136 insures that the speaker 88 will be short-circuited until the handle has been re turned to its normal position.

Another alternative form of wiring is il-.

lustratedin Fig. 8 whereby a selection of programs may be made by the operator of the coin control. In this diagram like numbers indicate like parts to those illustrated in Fig. 6. In Fig. 8 the knife switch 66 has one terminal connected b lines 67, 68 and 69 to one power input terminal of the phonograph 54, amplifier 57 and radio receiver 58 respectively as before. The other terminal of knife switch 66 is connected by a line 90 to each of the contact members 480 in each ofthe control boxes 9. A three-circuit two-way switch 91 is provided for each control box 9. A terminal 92 of the said switch is connected direct to the contact member 47 c. When the switch 91 is positioned as shown in Fig. 8 the contact 92 is connected by a line 95 with the second of the power input terminals 61 of the radio receiver 58. Thus, with the switch in this position the insertion of a coin and the operation of the control box handle completes a power circuit to actuate the radio receiver. When the switch 91 is thrown into the opposite position the terminal 92 is connected by a line 96 to the second of the power input terminals of the phonograph and to the second of the power input terminals 63 of the amplifier. The operation of the coin control with the switch in this position therefor supplies power to actuate the phonograph and its amplifier. I

The switch 91 is also provided with a. terminal 93 and a terminal 94 connected respectively to oneof the contact members 36 and 36a. The opposite members 36 and 3611 are connected as before to contact members 47 b and 470. respectively. The contact members 486 and 48a are connected as before to the speaker 88. When switch member 91 is positioned to actuate the radio receiver the terminals 93 and 94 are connected by a pair of lines 97 with the output terminals 62 ofthe said radio receiver, thus connecting the speaker thereto for radio reception upon the operation of the coin control. When. the switch 91 is oppositely positioned the terminals 93 and 94 are connected by a pair of lines 98 with the output terminals of the phonograph amplifier for phonograph reception upon actuation of the coin control.
