Application filed March 7, 1930. Serial No. 433,952.

The present invention relates to radios, and comprehends means for automatically operating the switch thereof with a view of turn- 7 ing said switch on or on at a predetermined period as may be desired.

In carrying out the invention I provide a novel construction of time controlled mechanism, capable of being easily and conveniently connected with the switch of the instrument, so that the latter can be automatically called into use, or rendered inactive-when in use, at any desired or predetermined interval.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the

invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and v wherein;

Figure 1 is a front elevation of a radio 5 invention.

Figure 2 is a fragmentary view of the radio as showing how the invention is associated therewith.

Figure 3 is a sectional view on line 33 of I Figure 2.

igure 4 is a detailed sectional view. Referring to the drawings in detail, 10 indicates a radio of any desired construction, while 11 represents the switch operating knob mounted upon the shaft 12 in the usual well known manner.

In accordance with the present invention, I employ a small alarm clock, indicated at 13, which is mounted upon the front wall of the radio cabinet or casing 10 as clearly illus trated in Figure 1.

Mounted upon the inner face of the front wall and arranged directly beneath the clock 13' is a train of gearing which is operated from i the time mechanism'of the clock, and which gearing can be quickly and conveniently operatively connected with the shaft 12 of the switch of the radio, so that the latter can be automatically called into use, or rendered embodying the subject matter of the'present' inactive when in use at any predetermined period of time.

The gearing above referred to is supported between'a pair of spaced parallel vertically disposed bars 14 and 15 respectively, and as clearly illustrated in Figure 2 the latter mentioned bar 15 has. its lower portion slightly ofi'set'as at 16. J ournalled between the corresponding upper extremities of these bars is a gear 17 which meshes with the adjacent gear v18 of the clock mechanism, while jour-- nalled between the said bars adjacent the lower ends thereof is a gear 19. This gear is carried by shaft 20 which also has mounted thereon a grooved pulley 21, and trained over this pulley and also over a similar but smaller pulley 22 is an endless belt 23. The pulley 22 is of course fixed to the shaft" 12 of the switch of-the radio.

Journalled in suitable bearings provided in the bars 14 and 15 at an appropriate point in their length is a shaft 24, and carried by this shaft is alarge gear 25. Also mounted on-the shaft 24 is a pair of spaced arms which are located betweenthe bars 14 and 15 and arranged transversely thereof. Each of these arms is indicated at 26, and each arm is formed with a relatively broad extremity 27 between which is journalled a pair of gears indicated at 28 and 29 respectively. A similar gear 30 is journalled between the opposite corresponding extremities of the arms 26, and as clearly illustrated in Figure 3, the gears 17, 28 and 30 all mesh with the gear 25. The shaft 24 is mounted for rotation, and is actuated by-means of a knob 31 upon the shaft 7 and arranged exteriorly of the radio casing or cabinet, and this knob is provided with of the present invention, during which in the well known manner. Then, the knob 31 is turned to the left or on position as illustrated in Figure 1, whereupon the arms 26 are shifted to bring the gear 29 into engagement with the gear 19. WV hen the proper interval of time arrives, for which the alarm mechanism of the clock has been set, motion is transmitted to the gear mechanism carried by the opposed bars 14: and 15, from the gear 18 of the clock mechanism as will be readily understood. Consequently, when the gear 29 is rotated, it imparts similar motion to the gear 19, whereupon the shaft 12 of the switch is turned by reason of its connection with the shaft 20 upon which the gear 19 is supported. Manifestly when the shaft 12 is rotated in this manner, the switch of the radio is turned on and the instrument auto matically calledinto use.

Again, should the radio be in use, and it is desired to automatically render the same inactive at a predetermined interval of time, it is only necessary to set the alarm mechanism of the clock accordingly, and rotate the shaft 24 to bring the gear 29. into meshing engagement with the gear 19 above referred to. Of course under these circumstances, the switch of the radio will occupyits on position, but when the particular hour or minute arrives at which it is desired to render the instrument inactive, motion is transmitted to the gear 29 from the gear 18 of the alarm train of the clock, through a train of gearing supported by the bars'14 and 15, whereupon the shaft 12 of the switch will be rotated in a proper direction to close the switch."

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily understood, I desire to have it known that I do not limit myself to what is herein illustrated and de" scribed and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim is:

1. In a radio including a switch, clock mechanism having an alarm train supported thereby, rotatable means arranged within the radio for providing a connection between the alarm train of the clock and switch to automatically open or close the latter at a predetermined interval, and pivoted lever means for moving .the rotatable means into and out of engagement with the switch.

said arms, and other gears mounted on said frame and connecting the above mentioned gears with the alarm train of the clock of and for the purpose specified.

LEMUAL GREEN BROWN.
