8 Claims.
The present invention relates to a radio antenna of the type adapted to be mounted on the exterior of an automobile, as for instance on the cowl or fender.
Antennas of this nature are intended to be used on different models of vehicle and this means that they should be adaptable to, various surface shapes in order that they may be easily mounted under all conditions of use. As the surface of a vehicle on which the antenna is mounted is frequently shaped differently for each model it becomes desirable to have a universal type of mounting which can be used.
Such mountings have been attempted in the past, but have been subject to the objection that they are unsightly in appearance and do not readily lend themselves to adjustment to the desired surface.
The chief object of the present invention has been to provide an antenna of the class described which is mounted in a hollow casing, which casing in turn is secured to the vehicle body. Another object of the invention has been to provide for relative adjustment between the antenna proper and the casing in order that the antenna may be mounted at the desired angle, irrespective of the surface on which it is secured. A further object of the invention has been to provide an efiicient electrical connection througli the casing between the lead-in wire and the antenna, while at the same time insulating the various parts from the metal surface of the automobile body.
To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims; the annexed drawing and the following description setting forth in detail certain structure embodying the invention, such disclosed means constituting, however, but one of various forms in which the principle of the invention may be used.
In said annexed drawing:
Fig. 1 is a schematic view of an automobile with my improved antenna mounted thereon; and
Fig. 2 is a vertical section through the antenna showing the parts in detail.
In Fig. 1 an insulating antenna casing Ill is shown mounted on a fender |2 of an automobile. I3 and H are portions of the extended aerial.
Referring more particularly to Fig. 2 the casing I is shown as aflixed to the fender |2 by a threaded stud I6, carrying a locking nut H and a washer |8. An insulator gasket 20 is interposed between the fender l2 and the wall of easing ID. A threaded plate 2| screwed onto stud I6 serves with nut H to fasten the casing on the fender. Preferably two studs It with their associated locking parts are used, one at each side of the casing Ill.
The aerial consists of several hollow metal tubes, two of which are shown in the drawing and designated by l3 and I4. The uppermost portion I9 usually consists in a rod carrying a ball-shaped knob 2| which prevents the rod from sliding inside tube Hi. The construction of this part of the device is well known in the art and not explained in further detail.
The lowermost of the telescoping parts of the device l3 has a metal ring 22 rigidly, secured thereto, for instance by soldering or brazing, and the ring has a cup-shaped portion 23 formed thereon fitting to the curved outside of a boss 24 in the way of a ball and socket joint.
The bottom end of tube I3 is pinned to a threaded stud 25. The latter carries a square nut 26 having an internal thread engaging with the thread on stud 25 and having a series of narrow parallel grooves on the upper face. These grooves are adapted to engage with the serrated portion 28 of two segments 29, one at each side of stud 25. Segments 29 have interiorly flanged end portions which meet each other to form a back wall which fits into a recess 30 in the end wall of casing Ill. The other end of segments 29 each have an opening 3| in which a pin 32 is received with its ends projecting on both sides. On said pin 32 a substantially V-shaped spring 34 is mounted by means of loops 35. The bottom end of the spring has a third loop which serves to receive a threaded stud 31 forming part of the lead-in from the antenna to the receiver set. The lower part of spring 34 is received in a cutout portion of easing IB and held against said casing by an insert plate 44. A lock screw 21 fastened to the bottom end of stud 25 serves to hold parts 25 and 26 as well as tube l3 assembled. A bore 33 in the bottom portion of casing l0 gives access to said screw 21 for mounting or dismounting the aerial.
The above mentioned stud 31 forming part of the lead-in is disposed in a plug of insulating material 40, which is housed in a metal casing 4|. At the rear end stud 31 abuts on a spring 42 which connects to the wire core 43 of a cable 45. The cable comprises a metal tube 45 with a flange 41 adapted to connect the cable and portion 4| of the antenna by friction. Insulating material is interposed between the sleeve 46 and wire 43. The main portion of the cable consists of a metal tube 49 shielded by a braided wire covering 50, which is used in a known manner for picking up disturbing noises in the surrounding atmosphere and improving the radio reception thereby. A plug 5| at the end of the cable serves for connecting the antenna to a receiver set in the usual manner.
For adjusting the aerial to'the desired angle,
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by any of the following claims or the [equivalent of such stated means be employed.
