UNITED STATES PROGRAM INDICATOR Jesse H. Davidson and John F. Mullancy, Colorado Springs, Colo.

Application November 1, 1932, Serial No. 640,672 9 claims. (ol. io-32') Our invention relates to improvements in program indicators, for schools or other audiences and more especially for radio audiences, as i1- lustrated herein, in which a moving, endless, belt- 5 sheet carrying the program is actuated by a clock motor to disclose and indicate the various desired programs at all times of day or night; and the principal objects of our invention are to afford facilities for showing on the moving, endless program-sheet the desired events at the designated time and at the designated broadcasting station for the whole weeks time; second, to designate on a clock driven endless belt sheet, lectures, theatricals, and important events as desired by the interested parties; third, to designate programs in schools and other gatherings of per; sons, as to time and place and other predetermined events; fourth, to indicate the time of day in a scale of periods of 15 minutes for radios, and for such other scales as desired in the various programs in the lines of business or amusements.

We attain these objects by means of the mechanisms and appliances illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the program indicator showing columns N. B. C. 26, and C. B. C. 27, the broadcasting companies, and a column 28 for such other broadcasting firms as desired; Fig. 2 is a sectional plan view of a part of Fig. 1 after removing the part above line A-A; Fig. 3 shows a detail of the friction clutch a, and pulleys, shown in Figs. 2 and 4; Fig. 4 is a right side sectional elevation of part of the frame 22 and working contents, without the casing or housing, as shown on the line BB, Fig. 1; Fig. 5 is a diagrammatic detail of part of Fig. 4, and showing the connections of the tension roller b which are similar to connections on tension roller c; Fig. 6 is a front elevation of the day-of-the-week d, endless belt, mounted on its three rollers, with housing removed, and also shown in Figs. 1 and 4; Fig. 7 is a front elevation of part of the program indicator endless belt 7, with housing removed; endless belt 7 is also shown in Figs. l, 4, 5.

Similar numerals refer to similar parts throughout the several views.

rI'he inside frame 22, carrying the rollers 6 and 18, the program indicator endless belt 7 with its marginal time-table, the rollers 19 and 11 with their endless belt d, and the actuating clock motor mechanism form the principal part of our invention. The clock motor 1 is there shown actuated by electric current and is provided to run all the time as a clock might run and a switch 23, Fig. 2 shows hcw the lights may be switched on and oir as desired. The motor 1 is connected with the current supply by means of supply means 24, Fig. 1, and drives shaft 32 which drives friction clutch member a, carrying sprocket pulleys 4 and 9 which drive chains 2 and 10 respectively. The speed of the invention is regulated within the clock motor which is only a part of our invention as used in combination, only.

Pulleys 4 and 9 are mounted loosely 'on shaft 32 except as made rigid by means of the coil tension spring 30 secured against them by removable tension pin 33. Chain 2 drives pulley 3 which actuates program indicator endless belt 7, as it is interwoven over the twelve rollers shown in Fig. 4, which are adapted to keep the endless belt in order and from chang the writing upon its face. But the rollers 18, may be dispensed with and the said belt be allowed to recline on the iloor of frame 22. y

Chain 10 drives pulley l2 and actuates indicator endless belt d, which indicates the days of the week. Ihe two idle rollers 19 support the face of belt d. The tension rollers b and c, Fig. 4, are forced by the springs 13, against their respective belts 7 and d, to add friction on the driving rollers 6 and l1, and their belts respectively.

'Ihe adjusting hand-wheel 5 on shaft 8 is adapted to regulate the position oi belt 7 by loosening chain 2, by its slipping pulley 4 in friction clutch a, by the slight tension of spring 30. The glass plate l5 in Fig. 4 is to protect the endless belt 7 from behind and especially when writing on it. This plate is transparent and the belt is partially so to enable one to read the writing on it when illuminated by the two lights 16, 16. The lights 17, 17, are to illuminate the belt d, which carries the days of the week.

The indicator belt 7, may be lined with a plurality of columns in erasable or permanent pigment, and usually the left marginal column 20, is indelibly printed in figures giving the time of day and night for one hundred sixty eight hours in spaces oi l5 minutes each, for radios and the seven days of the week in order, and the whole printed in transverse horizontal lines, equally distant in four for each hour, on which a person may write with a pencil pressing the belt 7 against the glass plate 15, to write or to erase any Writing. The number oi spaces to pass each hour is optional as desired, as four or more spaces.

The time of day and the time for program action is indicated by the pointing arrow head 21, Fig. l, which points to the line passing it.

The two endless belts 7 and d and the clock motor 1 are intended to run all the time like a clock, but the lights may be switched oil as desired. The movement of the belts is so slow that but a very little electric energy is required to run them, and it may be done by a small dry battery with little notice, as a clock. But this clock motor may be actuated by a compressed spring, or by a weight or otherwise, as well as by an electric current.

In Fig. 1, the casing or housing 25, carries a card holder or container 29 for holding of cards.

In Fig. 3 the hub 31 is shown rigidly pinned to shaft 32 so as to turn the pulleys 4 and 9 by frictional contact when pressed by spring 30, forcing the discs of the clutch together. While we are herein representing the endless belt 7, as running upwardly, we claim the invention of running it downwardly or horizontally. While we show the indicator as mounted in a separate housing, yet we claim the use of the endless belt 7, mounted within the housing of a radio receiving member or other program member. And while we show the endless belt d, as indicating the days of the week only, yet we claim the invention of showing the days of the week on the endless belt 7, in its various forms, and dispensing with endless belt d.
