3 Claims.

This invention relates to a program selector, and more particularly to a program and station indicator which will facilitate the selection of programs and the tuning of radio receivers. This, therefore, is the general object of the present invention.

Present day radio receiving sets are generally provided with stationary dials calibrated in wave lengths or kilocycles, in numerical order. For the convenience of the radio listeners, newspagrams in their columns. Nevertheless, it has been found difficult for the operator of a receiving set to tune a desired program, because no relationship exists between the alphabetical order of the call letters of the broadcast stations and the numerical number of the wave length assigned to the respective station. Attempts have been made to overcome this diiculty by providing the radio receivers with individual push buttons, each of which selects a predetermined Wave length or broadcast station. However, the use of such sys-A tems are of but little assistance for the selection of a specic program unless the station broadcasting such program is known.

An object of the present invention is to provide a device which will facilitate the dial setting of the receiver in kilocycles for a particular station call letter, and which device Will also aid the operator of the receiver to ascertain the call letters or station identication of a broadcast for which the receiver dial is set. These, therefore, are more specific objects of this invention.

Another object of the present invention is to provide a radio station finder and identifier Which may be manually or automatically operated at intermittent intervals to disclose the various radio programs being broadcast at stated time intervals and the broadcast stations carrying such programs.

It is another object of my invention to provide a program and station indicator which may be built in connection with a radio-receiving set or without connection to a receiving set to be of special value for short wave listeners.

Other objects of this invention will become more apparent from the following description, reference being had to a preferred embodiment oi the invention illustrated in the accompanying drawings. The essential and novel characteristics of the invention will be summarized in the claims.

In the drawings, Fig. l is a perspective view of my radio broadcast station identifier and program selector; Fig. 2 is a rear elevation of the device with the back cover removed; Fig. 3 is a vertical section on an enlarged scale as indicated by the lines 3-3 on Fig. 2; Fig. 4 is a sectional detail taken along the horizontal plane designated by the lines 4-4 on Fig. 3; and Fig. 5 is ,10 pers and magazines are printing the daily proa sectional detail as indicated by the lines 5-5 on Fig. 4.

My improved radio station and program indicator in general comprises a housing or cover in which is mounted a movable indicator member, selected portions of which are visible through comparatively small selector openings..

in the housing or cover. The indicator is provided With a list of the station identification or call letters of radio broadcast stations arranged in alphabetical order, and adjacent thereto to the Wave length of the stations. The list is so arranged that when a selected call letter is moved to an indicating position, relative to the housing, the Wave length in kilocycles of such station, its power in Watts, the location of such station, and the name of the system to which such station is a member, will be brought into view. The indicator likewise is provided with a list of Wave lengths in numerical order, any one of which when brought into indicating position brings the respective call letters of the broadcast station at such wave length into an indicating position, and may besides reveal power in watts, location and network.

Programs are selected from a manual or automatically movable chart, also visible through openings in the housing or cover. Such chart is provided with a list of the various programs by name and the call letters oi the station over which they may be heard, and are arranged in groups, each group giving the program for a predetermined time interval, for instance, fteen minutes. The program chart is automatically progressed every fteen minutes so that only the programs for the selected time interval are visible.

Referring now to the drawings, and especially to Figs. 1 and 2, I have shown a housing I0 having a front panel II provided with openings I2 and I2a., I4 and I4a, and I5. On the inner surface of the panel, I mount a plurality of rollers 20 provided With suitable grooves to engage the periphery of an indicating dial or disc 2|. One area of this disc is provided with a list of wave lengths in numerical order as indicated at 22, and which when aligned with an indicating mark 23 associated with the opening I4 of the housing will position the name oi the broadcast station and its call letters, also carried by the disc, opposite an indicating mark 24 associated with the opening I4a of the housing. The indicating disc also is provided with a second list of broadcast station call letters arranged in alphabetical order. A portion of this latter list is indicated in Fig. 1 at 25. The arrangement of this second list is such that when a predetermined call letter is positioned opposite an indicator line 26 on the face of the panel, the Wave length assigned to the corresponding broadcast station and data giving the location of such station, carried by the disc will be opposite an indicating line 21 and visible through the opening |2a in the panel.

The indicator disc 2| may be manually rotated to select either the call letter or wave length desired and position them opposite their respective indicating marks. For this purpose, as shown in Fig. 3, I mount on the face of the panel an operating knob 3i). This knob is secured to a-shait 3| rotatably journalled in any suitable manner in the panel |I and extending therethrough, and within the housing, drivingly mounted on the shaft 3|, are a pair of discs 33. A spring 35 maintains the discs 33 in frictional engagement with opposite faces of a bead 34 secured to the edge of the indicating disc 2|. The arrangement is such that the rotation of the knob imparts a rotative movement to the dial.

The major radio programs of broadcasts for stated time intervals are printed on an elongated paper strip ist, a portion of which is visible through the opening I5 in the panel and an aligned central opening la in the indicating disc. The strip lill is so printed that its visible portion carries the programs for the selected time intervals; in this instance, fteen minute intervals, and a mechanism, hereinafter more fully described, is provided to advance the strip automatically every quarter hour. The programs are preferably set out by the name of the program and the call letters of the broadcast stations over which such programs are broadcast.

As shown in Fig, 3, the program strip 40 is rolled on a storage reel lli which is rotatably mounted within the housing Iii. The strip passes from the reel 3i to a guide roll 42, and then upwardly immediately behind the indicator disc 2|, to a second guide roll S3 at the upper end of the housing, and thence downwardly about a driving drum i4 to a take-up roll 45 on which the strip is rewound. The strip 40 is provided adjacent each edge with a Aseries of perforation openings #lila (Fig. 2) which are engaged by pins lii of the driving drum member 44. To advance the printed strip iii), the Ydrum member 44 is rotated a predetermined amount every quarter hour for registration with the opening l5 in the panel and the take-up roll 45 rewinds it simultaneously.

rlhe driving drums *44 are actuated by a motor Eil, the operation of which is timed by a synchronous electric clock 55. As shown in Fig. 8, the driven shaft 56 of the clock is provided -with a contact 5i and makes one complete revolution every fteen minutes. The contact 5l bridges a pair of contacts 58 and 5g and thus completes the electric circuit to the motor 50. The -contact V51 also bridges contact 58 and 68 to energize a solenoid 3| which operates to momentarily raise a latch member S2 out of the path of a pivoted pawl 53. This pawl is carried by a Clutch member 64 which, together with the driving drumt, is secured to a shaft V655. The raising of this latch permits a spring 56 (Fig. 5) to draw the end Gl of the pawl into engagement with a driving hub 38. This hub is secured to a shaft 69, coaxially mounted with the shaft 65, and driven by the motor iii) through a driving belt lll and suitable `pulleys carried by the shaft E5 and Vmotor respectively. Consequent upon the rotation of the hub, the end 51 of the pawl 63 rides the periphery of the hub 63 until it is reached by a notch "il formed in the hub, whereupon, the shafts SS and 65 `rotate as a unit until the Voutwardly projecting end 'i3 of the paWl 63 strikes the latch B2 which has been returned to a latching position by a spring 15. The driving connection between the two shafts is thus disengaged.

The strip take-up roll 45 is driven by the motor 50 through the medium of a driving belt and suitable pulleys, the arrangement being such that the belt will slip upon its driving pulleys, the arrangement being such that the motor normally tends to drive the roll at a comparatively high rate of speed, damage to the strip being prevented by so arranging the driving belt as to permit it to slip on the associated pulleys or sheaves as long as the strip is taut. Overrunning of the strip is prevented by a friction brake which is resiliently applied to the periphery of the roll 4| by a suitable spring 8|.
