7 Claims.

This invention relates to apparatus for displaying radio programs.

One of its objects is the provision of a strip of paper bearing indicia of radio program numbers and of the respective times of broadcasting the same, the ends of said strip being adapted to be adhered to constitute it an endless band.

Another object is the provision of means for coordinating the sequence of display of said program numbers with the passage of time.

A further object is so to juxtapose a clock dial and the display of particular program numbers that the observer may at a glance note the time as indicated by the clock and the program numbers then available or about to become available, for reception.

A still further object is the provision of means for grouping and displaying, in point of time, the titles and the names of sponsors of a plurality of program numbers which, during a particular period, are simultaneously broadcast by different stations, in order that the radio user may make his selection of the number to which he wishes to listen.

It is at present customary for radio users to consult newspaper schedules of radio programs, the several numbers comprising each of which are generally grouped, with their respective broadcasting times, under a heading designating the station and its wave-length. In order that he may learn what numbers are available for selection, the user must locate his favorite stations in the more or less extensive schedule, and ascertain what each is to broacast at the particular time when he intends to tune in. Having made his .-"selection, he then consults a time-piece and tunes in at the beginning of the desired number. Ordinarily, however, the radio user prefers not to go to this trouble. Instead, he tunes in on one or other of his favorite stations, without knowing what it is then broadcasting, listens for a few moments, finds that he is not interested in that particular number; and then tries one or more other stations. When, eventually, he gets a number which appeals to him, he has lost some considerable portion of it.

With the present invention it is unnecessary for the radio user either to consult newspaper schedules of programs or to lose a portion of some interesting number while experimenting to find what he wants.

In accordance with this invention, the titles and the names of the sponsors of a plurality of program numbers simultaneously broadcast by several leading stations are grouped and displayed with reference to time of broadcasting, so that the user may have before him information as to the numbers available from such stations during any quarter-hour period of the day, and during any day of the week, month and year.

The invention will best be understood by reference to the accompanying drawings, wherein like reference characters indicate like parts, and wherein Fig. l is a front elevation, partly in section, of 10 apparatus embodying one of the present preferred embodiments of the invention.

Fig 9 is a section taken on the line 99 of Fig.

8, viewed in the direction indicated by the arrows.

Fig. 10 is a vertical sectional view of a still further modified embodiment of the invention.

Referring to the drawings: A cabinet, indicated generally by the reference numeral l, is provided with a removable back plate 2, and with a viewing aperture 3 in its front wall. Mounted on the inner top surface of this cabinet is a housing 4, containing an electric or spring-wound clock mechanism (not shown). Projecting through apertures in the back plate 2 are shafts carrying, respectively, a clock-starting knob 5 and a clocksetting knob 6. The clock mechanism rotates a cylindrical sleeve 1, carrying the second hand Ia of the clock and also carrying a worm 8. This worm meshes with and drives a worm-wheel 9, mounted on a shaft H], which is rotatably supported at its ends in bearings in a frame ll, mounted in the cabinet I. Also mounted on shaft [0 and rotatable therewith is a flexible pawl l2,'constructed and arranged progressively to enprojecting end carries a similar knob, 24.

gage the teeth of a ratchet-wheel I3. The wormwheel 9 is provided with fifteen teeth, and its driving worm 8 is of the single-thread type. Thus,

-the worm-wheel will be rotated once in fifteen minutes; and the pawl I2 will engage a ratchet- Wheel tooth once during such period, rotating the ratchet-Wheel and the feed roll I4 (on which it is mounted) a distance of one tooth.

As appears from Fig. 1, driving feed roll I4 carries at the right-hand end of its supporting shaft a spur gear I5, which meshes with and drives another spur gear I6, carried by the supporting shaft of a coacting feed roll ll. of the apparatus, an endless band of paper, I8, is fed between rolls I4 and I1, being held taut by the action of idler rolls I9 and 20. ing shafts of these idler rolls also have their bearings in the frame II, and also are provided with coacting spur gears, 2I and 22 (Fig. 1). For the purpose of manual adjustment of the band of paper, I8, the shaft of driven feed roll I! pro- .jects through an aperture in the side of cabinet I, and this projecting end carries a knob 23. For the same purpose, the shaft of idler roll I9 also projects through the side of the cabinet, and its The four rolls are preferably provided with soft rubber surfaces in order to insure positive feeding of the paperband I8.

As further appearsfrom Fig. 1, the front surface of the paper band I8 has printed or written upon it indicia which divide it vertically into quarter-hour periods and into daily periods. In horizontal alignment with each such quarterhour indication are the titles and the names of the sponsors of a plurality of radio-program numbers which are to be simultaneously broadcast, at the indicated time, by the user's favorite stations.

The mode of operation of the apparatus is as follows: The back plate of the cabinet is removed, and one end of the paper record I8 (which, at that time, is in the form of a strip) is inserted between idler rolls I9 and 20. The adjusting knob 24 is then manually turned in a clockwise direction, thus rotating idler roll I9, and, through gears 2I and 22, idler roll 20-thereby upwardly feeding the paper strip until its leading end is in position to be engaged by driving feed roll I4 and driven feed roll I1. Adjusting knob 23 is then manually turned in a clockwise direction, thus rotating driven feed roll I1, and, through gears I6 and I5, driving feed roll I4, thereby feeding the paper strip through said latter rolls. The rotation of driven feed roll I! and driving feed roll I4, through manual turning of adjusting knob 23, is rendered possible by reason of the flexibility of pawl I2, which permits it to ride over the teeth of ratchet-wheel I3. When the leading end, I8a, of the strip has been fed through rolls I1 and I4 a sufficient distance, the trailing end, I8b, is attached thereto, as by application of an adhesivethe strip being thus converted into an endless paper band. The band is then manually fed through the rolls until a desired series of program numbers becomes visible at or near the upper edge of the viewing aperture 3. The back plate 2 is then restored to position, and the clock mechanism is started and set by manipulation of knobs 5 and 6, respectively. The feeding mechanism will then continue to function, in the manner hereinbefore described. to maintain the display of the several program numbers in synchronism with the times at which they are broadcast, as indicated by the clock. The paper In the operation" The supportband may, if desired, be illuminated by light rays projected therethrough from a lamp or lamps, such as 25.

Fig. 4 shows in front elevation rolls and actuating mechanism therefor, of modified form. In order to minimize the likelihood of irregular feeding of the paper band I8 (Figsfll and 3), by reason of lack of uniformity of pressure between said paper band and the long driving and driven feed rolls, I4 and I1, respectively (Fig. 1), and between said paper band and the long idler rolls, I9 and 20, respectively (Figs. 1 and 3), the area of driving contact may be reduced, as by employing two relatively short rolls such as Mr: and Nb, pressing against correspondingly short portions of the driven feed roll Ila. Similarly, the contact between the idler rolls may be limited to a short portion, 20a, on the lower idler roll, pressing against a correspondingly short portion of the upper idler roll, I So. The surfaces of rolls I4a, I41) and 20a may consist of soft rubber, and the respective coacting rolls Ila and I9a may be of metal or other suitable material. As an alternative to spring pawl I2 of Figs. 1, 2 and 3, there may be mounted on shaft Illa a hub member having integral therewith a single tooth, I2a, thus constituting it a single-tooth gear. At each revolution of shaft I (la, this tooth I2a engages one of the teeth of a fifteen-tooth spur gear, I3a which is rotatably mounted on the shaft I3b, between spacing rings 26 and 21 (Figs. 4 and 7). Spacing rings 26 and 2'! may be attached to shaft I3b in any suitable manner, as by set-screws 28 and 29 (Fig.7). A dished spider spring 30 (Figs. 6 and 7) is supported by shaft I3b, between spacing ring 26 and spur gear I 3a. Formed in the hub portion of this spider spring is a finger 3|, projecting at a right angle from the hub portion and adapted to enter a recess formed in the face of the spacing ring 26. This forms a connection whereby said spacing ring drives said spider spring, through rotation of shaft I3b (Fig. 7). In initially assembling the several members on the shaft I3b, one of the spacing rings, such as 26, is attached to said shaft against longitudinal or rotary movement, and the spider spring 30 is placedon the shaft with its finger 3| entering the recess in the face of said spacing ring. The spur gear I3a and the spacing ring 21 are'then moved along the shaft and brought into such position thereon that the three arms of the spider spring 30 are sufficiently flexed to provide a frictional driving connection between such arms and the face of spur gear I So contacting therewith; and to provide a similar frictional driving connection between the opposed faces of said gear and of the spacing ring 21. This friction is adequate to insure that the tooth I2a will rotate the spur ear I3a, in order automatically to feed the paper band I8. This frictional engagement may, however, be overcome by force manually applied to rotate adjusting knob 23a (Fig. 4). Thus it becomes possible manually to rotate driven feed roll I'la and driving feed rolls I 4a and Nb, for purposes of adjusting the paper band, even though the single-tooth gear I2a may happen at the time to be in locked position with reference to one of the teeth of spur gear I3a, as shown in Fig. 5.

In the further modified embodiment of the invention shown in Figs. 8 and 9, the clock mechanism contained in housing 4 (Fig. 8) is provided with a solid shaft 1b for driving the second hand, To. This second hand shaft rotates in a tubular shaft 33 which drives the minute wheel, 31. Extending into the bore of this wormwheel is an integral key, 33, engaging a spline 39 in a shaft lllb, havlng its bearings in the frame ll. Supported by' the shaft lllb are two rolls, 40 and 4|, which are rotatable on the shaft under certain conditions to be hereinafter described. Attached to roll 40 is a short sleeve 42, preferably of soft rubber, for feeding the paper band l8c. A similar sleeve 43 is attached to roll 4|.

Attached to the projecting end of shaft I!) is a dished spider spring 30a, similar to the spring 30 of Figs. 4, 6 and 7. This spring is flexed (by pressure applied by a nut 44) between a shoulder formed on said shaft lflb and a spur gear l5b. This spur gear is rotatably mounted on shaft I Oh, but the pressure exerted by dished spring 30a creates sumcient friction between the spring, the gear IN), a washer 45, and said nut 44 to enable said gear to drive a coacting gear l6b, attached to a sleeve 46, connected by a pin 41 to a driven feed roll "D. A roll-adjusting key 48, adapted to be inserted in the bore of sleeve 46, is provided with a slot 49 for engaging the pin 41, in order that the driven feed roll "b may be manually rotated.

In this embodiment of the invention there is provided (Fig. 8) a two-piece guide 50 for the paper band I80. Formed in each of the side walls of the frame ll (Fig. 9) is a recess 5l' I, are omitted, the guide 50, the recesses 5|, and

'the channels 52 being substituted therefor and co-operating to maintain the paper band I80 in proper feeding position.

In operating this embodiment, the back plate 2 is removed from the cabinet, the trailing end l8d of the paper band I80 (which, at that time, is in theform of a strip) is threaded between the two members of the guide 50 and into engagement with the rubber sleeves 42 and 430i the driving feed rolls 4B and 4| and with the coacting driven feed roll III), the margins of the band entering the recesses 5|. The key 48 is then inserted in the sleeve 46 (Fig. 9), and its slot 49 is engaged with pin 41. Driven feed roll l'lb is then manually rotated in a counterclockwise direction to feed the end of the strip downwardly through the channels 52 and back into the main body of the cabinet I. The friction of said strip between feed roll Nb and rubber sleeves 42 and 43 causes the rolls 40 and 4| to rotate on the shaft lb. The leading end, l8e, of the strip is then adhered to the end l8d, thus converting the strip into an endless paper band. This manual feeding is made possible by reason of the fact that, while worm-wheel 31 and worm 38 lock driving shaft lllb against such rotation, spur gear ISD is caused to rotate'on said driving shaft against the friction produced by flexure of dished spring 30a; and

because of the further fact that rolls 40 and 4| are caused, in the manner described, to rotate on their shaft lilb.

Alternatively, the leading end of the paper band llc may be initially threaded into the channels 52 and upwardly into engagement with feed roll no and rubber sleeves 42 and 43. In this case, key 48 will be manually rotated in a clockwise direction to feed said leading end downwardly between the two members of the guide 50.

Whichever method may be employed for threading the paper strip, when it has been properly positioned and its ends have been adhered, the clock is set by rotating the projecting shaft 60.

The quadruple-thread worm 36 being mounted on sleeve 35, and this. sleeve being mounted on the tubular minute-hand shaft 33, the worm-- wheel 31 will be rotated the distance of one tooth every quarter hour. The time divisions on the record l8 (Fig. 1) are correspondingly spaced.

The hour hand of the clock is driven in the following manner: A pinion 53 (Fig. 8), attached to the sleeve 35 which carries the quadruplethread worm 36, meshes with and drives a gear 54, attached to one end of a countershaft 55. Attached to the opposite end of said countershaft is another pinion 56, which meshes with and drives another gear 51, attached to a sleeve 58, rotatably mounted on the minute-hand sleeve 33, and carrying the hour hand 59. The ratio of this gear train is 1:12.

In this embodiment of the invention, the housing 4 which contains the clock motor is attached by a bracket 6| to the partition wall 62 of the frame I I,

In the still further embodiment shown in Fig. 10, an opentop container 63 is attached to the back plate 2 of the cabinet I. The purpose of this container is to receive program records which are on separate sheets or thin cards, such as 64, rather than on along web. Such cards may, for example, contain programs covering a single day. They are to be threaded into the feeding mechanism and fed therethrough in the same manner as the web records.

As is well known, the programs of the larger broadcasting stations are, to a considerable degree, permanent as to their principal features, 1. e., certain numbers are regularly broadcast at definite times on definite days. For this reason, the endless paper band l8 may be fed for perhaps several weeks before sufficient program changes have been made to render it obsolete. During this period. it Will, as to the principal program numbers of the users favorite stations, at all times show the day, the hour and the minute at which such numbers are to be broadcast. The clock element will show the actual times at which the user is to tune in on a station in order to listen to the desired numbers.

It is contemplated that users of the apparatus shall, from time to time, be furnished revised program strips or sheets. In the interim, they may make revisions in writing. Moreover, blank spaces are provided (such as those adjacent the words Tuesday morning in Fig. l), to enable them to write in data relating to any additional programs in which they may be interested.

In addition to the hereinbefore-described advantages of the apparatus, by way of convenience to the radio user, it embodies the further desirable feature of serving as an advertising medium for the sponsors of the programs-the names of the sponsors and/or their products being printed on the paper band in association with the titles of the respective program numbers.

It is to be understood that the preferred embodiments oi. the invention shown in the drawings and described in the specification are merely illustrative; and that, without departing from its principles, the invention may be embodied in other and different forms and structures.
