ILLUIINATBD RADIO ANTENNA Filed Jan. 21, 1946' INVENTOR.

fry/ 3 5 51/006?! Patented June 21, 1949 UNITED STATES PATENT OFFICE ILLUMINA'I'ED RADIO ANTENNA Francis G. Wood, East Detroit, Mich.

Application January 21, 1946, Serial No. 842,484

1 Claim.

This invention relates to radio antennas and in particular to such antennas for vehicles, such as automobiles.

One object of this invention is to provide a combined radio antenna and safety light, especially for mounting upon a vehicle, such as an automobile.

Another object is to provide a radio antenna secured in a translucent plastic rod together with means for illuminating the rod, thereby enabling the antenna to function also as a safety light for the vehicle, and at the same time protecting the antenna conductor from corrosion.

Another object is to provide an illuminated radio antenna mounted in a transparent plastic rod which is illuminated near one end thereof, the light being carried up the rod in such a manner that the rod is illuminated throughout substantially its entire length, thereby serving as a warning light to vehicles approaching from either side and serving to prevent collisions.

Another object is to provide an illuminated radio antenna for vehicles and the like as set forth in the preceding objects, wherein the translucent material of which the rod is made has optical properties of such a nature that the illumination of the rod near one end causes the rod to shine with a diflused glow which is sufllcient for warning purposes yet which will not be mistaken for ordinary driving lights.

Another object is to provide an illuminated radio antenna for vehicles and the like as set forth in the preceding objects wherein the supporting bracket for the antenna is also illuminated, it being of similar translucent material, suitably colored, if necessary, to conform with the vehicle lighting laws.

Another object is to provide an illuminated radio antenna for vehicles and the like, as set forth in the preceding objects, wherein a small aperture or window in the bottom bracket permits sufllcient light to shine downward, thereby illuminating a portion of the vehicle on the antenna side thereof.

Other objects and advantages of the invention will become apparent during the course of the following description of the accompanying drawings, wherein:

Figure 1 is a side elevation, partly in section, of an illuminated radio antenna according to a preferred embodiment of the invention:

Figure 2 is an approximately horizontal section along the line 2-2 in Figure 1;

Figure 3 is an approximately vertical section along the line 3-3 in Figure 1; and

Figure 4 is a diagrammatic side elevation of a portion of a vehicle with the illuminated radio antenna of this invention mounted thereon.

Referring to the drawing in detail, Figure 1 shows a preferred embodiment of the illuminated radio antenna of this invention, generally designated III, as consisting generally of an upright i I supported in brackets l2 and i3 secured to the side of a vehicle [4 (Figure 4). The upright H is of translucent material, preferably of translucent or transparent plastic, and has mounted therein a conductor l5 which serves as the radio antenna proper.

The upright II is sufliciently elongated to provide a suitable length for the antenna conductor I5 and the two may be molded in a single unit by methods well-known to the plastic molding industry. The upright ll is preferably tapered from its lower end It to its upper end l1, and may terminate in a pointed tip [8, if desired. The tapered shape of the upright i I provides not only a pleasing appearance but also a strong construction.

The illuminated radio antenna I0 is preferably supported in the lower bracket l3 by means of a clamp 20 encircling the groove 2| in the upright I I (Figures 2 and 3) and having a shank 22 which is threaded as at 23 and which passes through a hole 24 in the vehicle body panel 25 and is secured in place by the nut 26. The body panel 25 also contains a hole 21 through which the extension 28 of the conductor I5 passes on its way to the radio setmounted within the vehicle I4.

The intermediate portion of the upright l I within the -upper bracket i2 is secured to the body panel '25} by :a similar clamp 29 (Figure l) of similar construction to the clamp 20 and similarly secured. The clamp 29 is covered by a streamlined contoured cover 30 which is provided with apertures 3| and 32 encircling the upright II at the points where it enters and emerges from the cover 30.

The lower bracket l3 also preferably has a streamlined cover 33 which, in its most desirable form, is also of translucent plastic material, white or colored, as previously stated. The cover 33 is provided with an upper aperture 34 through which the upright ll projects upwardly, and a lower aperture 35, which may also have a window therein, if desired, the latter aperture serving to permit light to shine downwardly over the body of the vehicle. This downwardly shining light may serve not only to warn other drivers of the presence of the vehicle, but also to illuminate the 3 ground or runnin board near the door to assist in entering or alighting from the vehicle.

The cover 33 is also provided with a partition 36 therein (Figures 1 and 2) upon which is mounted a lamp socket 31 for receiving a lamp 38. The lamp 38 is energized by conductors 39 and 40 (Figure 2) passing through the body panel 25 by way of the aperture ll. The conductors 38 and 40 are connected to any suitable source of electric current, such as the storage battery or a car, by way of a switch mounted in any suitable location. such as on the dashboard or instrument panel of the vehicle.

In operation, the switch (not shown) is closed so as to energize the conductors l9 and 40 and light the lamp 38. The light from this lamp shines upwardly through the lower end I! of the upright II and is conducted upward through substantially the entire length thereof, causing the upright II to shine with a diflused glow which is visible for a great distance.

At the same time, light from the lamp 3! passes outward through "the translucent cover 33 of the bracket l3 and illuminates it, likewise serving as a warning light. Finally, a portion of the light shines downward through the aperture or window 35 onto the lower part of the body panel 25 and serves as an additional warning and also to illuminate the ground to assist in entering or alighting from the vehicle.

When the radio switch (not shown) is closed, the antenna conductor I5 is connected to the radio set and picks up radio waves which are conducted to the set, where they are detected or rectified and amplified in the usual manner, the signals being made audible by the loud speaker. Obviously, the device may be used as an antenna by day or by night. The translucent plastic body of the upright ll thus serves not only to conduct illumination but also to protect the antenna conductor it from corrosion and to strengthen it and support it in a suitably rigid manner.

While I have shown and described my invention in detail, it is to be understood that the same isto be limited only by the appended claims, for many changes may be made without departing from the spirit and scope of my invention.

What I'claim is: 7

An illuminated radio antenna for vehicles comprising an elongated upright of translucent material, an antenna conductor mounted within said upright and extending longitudinally therealong, a bracket enclosing a lower portion of said upright, and a. light source mounted within said bracket and positioned for projecting light upwardly into said upright, said bracket having a light-transmitting portion therein at the bottom thereof whereby to project light downwardly therefrom.
