' 1 claim. (01. 250- 20 This invention relates to improvements in radioapparatus and has particular reference t a program and station selector.

The principal object of .this invention is to fjprovide means for automatically turning on a radio program being broadcasted formingany one of a selected group of broadcasting stations.

Another object'of the invention is to produce a device which may be employed with any stand- ;ardradio receiving set now in use.

' A further object is to, produce a device of this character which is simple in construction and one which maybe actuated .by any member of the,

household. l

which is economical to manufacture.

Other objects and advantages will be apparent during the course of the following description. In'the. accompanying drawings forming a part ;:of this specification and in which like numerals the same,

It is often desirable to select from a broadcast program several features which would be entertaining and desirable to listen to. Up'to the present time it has been necessary, as far as applicant is aware, to select from the program those stations desired and then to manually turn on the radio at the designated hours and to tune the radio set to the station from which the particularprogram is emanating. It often there- ,fore occurs that a person misses a program A-still further-object is to produce a device of one of the through inadvertently forgetting to turn .on the radio receiving set or through the fact that a, person may be located inanother room and'unable to reach the radio asisoften the case with" invalids.

With my, apparatusgit is possible to select the, program desired from: any one of the numberof stations and to have the radio receiving set autos matically' turn on this station at the proper time. The apparatus willoperateover a period of twelve (12) hours and it is of course obvious that by using a twenty-four, (24) hour clock, the set. could be caused to operate over that period.

In the accompanying drawings wherein for the purpose of. illustration is shown a preferred embodiment. of my invention, the numeral 5 designates the face ,of a clock, which clock may bedrivenin any convenient manner; as for instance by a spring or by being electrically connected to the; customary house circuit. This clock has an,elonga'ted hour hand 6 which hour hand extends overa'plurality of concentric insu- 1 the circuit so that when this hour handcomes I into engagement with one of the arms 11 a cir cuit will be completed to the relay belonging to the particular ring in which the arm is located, and the action of this relay will be later described.

Referring now toFi ures 4 and 5 it will be noted that a motor is shown at 12 which motor is geared to a wheel 13 which in turn is adapted to drive a wheel 14 to which wheela crank 16, is pivoted. This crank is in turn pivoted as at 17 to awheel 18. This wheel 18 may be connected in any convenient manner to the tuning mechanism of the radio set and is mounted upon a shaft 19 which extends through the panel 21 and has a knob 22 thereon. This-knob is connected by a link'23 to a pivoted arm 24 which is in turn connected by a link 26 to the clutch. mechanism 27 mounted in the wheel 13, the purpose of which is to provide means whereby by pulling outwardly on the'knob 22 the clutch 27 may be actuated for' releasing the

wheels

13 and 14 so that the set may be manually actuated when desired. A pull rod 28'is pivoted to the pivot v to point Hand to the traveller 31 which moves between the tracks32. This traveller carries a stop gate which consists of a' pair of

arms

33 and 34 to which pivoted ends 36 and 37' respectively are attached. Thesepivoted ends each carry an insulating strip as shown at 38 and 39 the purpose of which will be later seen. Springs not shown serve to keep the pivoted ends in alignment with the arms.

Referring now to Figure 3, it will be noted that r a series of slots 41 are formed in thepanel- 21 and serve to position a plurality of knobs '42 to each ofwhichis connected an'electrical relay 43."

This relay carries a stop which may be moved into alignment with the

pivoted ends

36 and 37 of the gate. This relay 43 has one endelectri- 'cally connected to one of therings 7 and has its opposite end connected to a'motor relay 44, the opposite end of which is connected to the transformer wire 46, the transformer being shown at 45. The opposite side ofethe transformer isconnected by a wire 47 to the clock 5 and consequently the hand 6. The motor relay 44 is adapted to actuatea switch 48 to close. thecircuit between the

line wires

49 and 51 and the motor 52. The opposite side of the transformer =is also connected to the

line wires

49 and 51. This wire 46 is also connected to the traveller 31. A shunt wire 53 extends around the relay 43 and is connected to the stop 40.. There are as many relays 43 as there are rings '7, each ring being connected to its respective relay. f

The result of'this construction is that assuming that all knobs 42 are in alignment as shown in "'Figure 3 it is first necessary topull. out the knob. 22 which will release the clutch 27 after which.

the button 22 may be rotated and the radio receiving set tuned to a particular station. This will move th'etraveller ,31 andafter the station. has been tuned one of the relays; for instance the relay connected to the ring marked A will be moved until it isin al'ignm'ent with the traveller. Another station is now tuned in-and the secondrelay is moved until it is in" alignment with the traveller.

In the present showing ten stations might be tuned and the relays set for these'ten stations.

The'knob 22 is now moved into position to again I 'engage the clutch 27 after which actuation of the motor 27 will impart movement to the wheels 13 and" 14 and reciprocating movement to the wheel 18. V

Assuming now that it is desired to turn on a station at a pre-determined time and assuming that that particular station is the one for which through the relay 43 will pull the armature thereof in such a manner asto move the stop 40 In this manner as many'relays are moved as it isrdesired' to select stations. I

of this particular relay into alignment with the stop gate which is now moving toward it from either the right or the left along the tracks 32 the direction of movement depending upon the previous position of the slider. As either of the arms 36 or 3''! come into contact with the stop 40 they Will pivot and permit the stop to pars therebetweenbut at this time there will be no electrical connection between the'stop 40 and the stop gate, due to the

insulated pieces

38 and 39, but as soon as the. stop passes one of the pivoted ends of the gate it will engage the metal portion of the gate and will complete a circuit through the shunt wire around the relay 44 thus stopping the motor 52 and consequently the traveller 31'. As the wheel 18 is connected to'the at a definite position the wheel 18 will be'turnedfi to the station previously selected; As the hand 6'moves out of. engagement with the selector key the relay 43 will be released thus withdrawing the stop 40 and asa consequence when the hour hand reaches the next selector key the mechanism is free to operate as abovedescribed. I

It will thus be seen that I have-produced adevice wherein certain stops definitely positioned i may be contacted for the purposeof selecting a station and for driving "the tuning mechanism until that selected station has been tuned and to then 1-stop the mechanism so that" the 3 program may be properly received. v s It is to be understood that the form of my invention' herewith shown and'describedis tofbe taken as 'a preferred exampleof; the samean'd that various changes relative to the material,

size, shape I and arrangement of parts may be each of said rings, each of said contacts having an arm capable of being extended into the-path of movement of an arm carried by one of the clock hands, a remotelypositioned driving mechanism, a plurality of relays, each of said relays beingconnected to one of said; concentric rings, a movable stop carried by each of saidrelays and inventionor the scope of the subjoined' adapted to be actuated thereby, said;relays-beingf being connected to a' tuningapparatus whereby the stopping of said driving apparatus sition said tuning apparatus.
