(Cl. Z50-33) zo claims.
This -invention relates to means for raising and lowering radio antenna and especially one ofthe telescopic section type such as used on an automotive vehicle. i
In certain'of the-fish pole type of antennas, where the structurehasv been made of telescopic sections, it has been the' vpractice to raise and lower these by hand, requiring the operator to do this from the exterior of the vehicle.
More recently it has been proposed to operate the telescopic sections more or less automatically by some type of motor or by a hand operating means within the vehicle but the motor operative means is more expensive than the hand operative means. It is the principal object oi my present invention to provide a simple and inexpensive means for operating the collapsible sections of an antenna from the interior of the vehicle.
Other and ancilliary objects will be discerned from a reading of the following specification taken in connection with the annexed drawings wherein Figure 1 shows a fragmentary View of an automotive vehicle having the antenna in collapsed or retracted position and connected to one form of my improved operating means.
Figure 2 is a part sectional and part elevational view through the antenna operating means shown in Figure 1.
Figure 3 is a view on the line 3 3 of Figure 2.
Figure 4 is a fragmentary view showing a slightly modified construction of a detail ofthe device shown in Figure 2.

Figure 8 is aview on the line 8-8 of Figure 7.
Figure 9 is a View onthe line 9-9 of Figure 7.
Figure 10 is a View similar to Figure 2 but of a further modied construction.
Figure ll is a View on the line II-II of Fig'- Figure 16 is a view on the line Iii-I6 of Figure 15.
In the various Views wherein like numbers refer to corresponding parts, I is a vehicle to which a collapsible antenna 2 is attached, the
antenna extending through a portion of the hood 3 of the vehicle. Mounted on the cowl 4 is an operating device 5 made according to one of the forms of the construction hereinafter described.
The antenna operating means comprising what may be generally termed a reel having, as illustrated in Figure 2, a cylindrical or drum-shaped, metallic casing with a portion 6 fastened to the cowl 4 in any satisfactory manner as by screws 1. The casing is completed by a cover portion 8, which may be of insulating material, fastened to the portion 6 in any satisfactory manner as by screws 9. A slightly compressible gasket I0 may sometimes be used when the separate ring ZI is utilized for sealing the joint between the two portions 6 and 8 of the casing. Where the ring 2| is omitted, the cover 8 has its flange extended sufficiently to take up for the space occupied by the gasket I0.
Carried by the casing members is an operating shaft II having a knob I2 thereon for turning the shaft. Carried on the shaft I I and revoluble therewith is a drum type member I3. The peripheral surface of the drum I3 is spirally grooved to receive a coiled means I4. This means may be made up of steel spring wire Wound to fit the groove in the drum and to give substantial stiffness for stresses applied longitudinally of the member, for instance either a push or a pull but which leaves said means flexible or bendable. However, this means may be made up in some other manner to attain the result hereinafter pointed out.
'Ihe inner end I5 of the means I4 is securely fastened to the drum while the outerend I6 protrudes through the casing or an insulating portion I'I in the casing for connection to the inner surface of the collapsible antenna 2. The diameter of the drum I3 which is made of suit- .able insulating material, is such that the convolutions of the bendable or flexible member I4 line in close proximity to the inner surface of an insulator I8 which is fastened to the casing member 6 as by screws I9 and thereby forms part of the casing. By this arrangement the convolutions of the member I3 are held in their operative position within the spiral grooves of the drum I3.
Preferably the shaft II within the casing has pin 2D which is ixed in the wall of the casing and f its inner end projecting into a continuation of the groove and the drum provided for the member It. This construction acts to guide and steady the movement of the drum as the operaty ing shaft I I is turned.
In Figure 5 the construction is the same as in Figure 2 with the exception that the outer peripheral surface ofthe drum has no grooves therein but the convoluticns of the member I4 are in close relation with the inner peripheral surface of the iiange'of the member I8. The opposite edges of the drum are provided 'with projections 22 and 23 which serve to prevent the convolutions on the member I4 from slipping over the ends of the drum.
In Figure 6 the outer periphery of the drum I3 is provided with hook-like formations 35 co.- operating with projections 36 extending downwardly from the inner periphery of the flange of the member1 I8, thus forming substantially closed recesses for the turns of the cable I4.
In Figure 7 the face of the drum is provided with spiral grooves and the cable I4 is disposed therein. The free end I6 projects through a fiat funnel-shaped opening 24, the opening into the funnel being indicated at 25 in Figure 9, in the cover member 8 which in this case is preferably made of insulating material. In this case the ring 2 I if used, may be of metal.
In Figure 10 the drum I3 has a thick rim which has an annular recess within which the cable I4 is positioned, the width of the recess being slightly greater than the diameter of the flexible cable I4. While in this construction the member I8 is illustrated, it is obvious that it may be omitted, which is also the case with the construction shown in Figure '7, it being understood that in both cases the shaft would be provided with a bushing carried by the casing member 6.
In Figure 12 the drum is very similar to that of Figure 10, having the same type of groove 26 for the convolutions of the cable I4. In addition,
two pairs of oppositely disposed grooves 21-are' provided to receive projections 28 lcarried by a ring member 29 located in the bottom of the groove 26. A plurality of springs 30 are located in arcuately disposed recesses in the drum and press against the ring 29 so that as the projecting end I5 of the cable I4 is moved outwardly by turning the knob I2, the springs and ring is a pinion 33 which is adapted to engage teeth 34 positioned on one edge of the drum I3. By this arrangement, the frictional resistance to the operation of the member `I4 is reduced, thereby 75 making it very easy for the operator to raise and lower the antenna sections.
From what has been said it will be seen that I have provided an antenna operating reel of simple construction comprising a casing, and an operating shaft and a drum within the casing, the parts being so arranged that a member relatively sti longitudinally of its length can be easily and quickly movedby-the operator'to raise and lower the antenna to. which the extensible member is attached.
