The invention. is designed with the particular The elbow 5 is rotatably mounted at its oppopurpose in view of providing an outside aerial site end on one side wall of the cowl 9 of the "5 for automobiles which may be manipulated from automobile body H] for swinging movement 5' within the vehicle'by the driver into horizontal thereon to elevate the unit I from a horizontal position, as for instance when not in use, or forwardly extending position into upstanding into upstanding set positions at different angles position and vice versa and by means of the to the vertical as occasion may require. following devices.

The other end of the-section between the outer face of the cowl 9 and the I may be provided with a terminal ball 4 for a enlarged end l3 of said sleeve ll, whereby said purpose which will be understood. The unit member is adapted to be clamped between the may be formed of any suitable metal. The other sleeve and said cowl. A friction washer 22 is end of the section 3 is mounted in one end of' provided in the elbow 5 intermediate the enan elbow 5 preferably of insulating material, larged end I3 of sleeve II and the bottom of 50; such as Bakelite, and preferably by means of the countersink M of said elbow. A friction a reinforcing sleeve 6 suitably secured in said washer 2 3 is provided on the bearing sleeve H end of the elbow 5 and a pair of stud screws 1 on the inside of the cowl 9. A nut 23' is threaded into said elbow 5 and sleeve 5. The threaded onto the inner end of the bearing sleeve pd elbow 5 has formed therein a shoulder-.8 for. llagainstthe washer 23. The washer 23. bears.

against the rightangled end 24 of a sleeve operating member 25, said end 24 surrounding said sleeve II between the washer 23 and cowl 9. A coil spring 26 is sleeved onto the housing I5 intermediate the inner end of the bearing sleeve II and a collar 21 fast on said housing, said spring tending to urge the sleeve I 3 outwardly in the cowl 9, and said nut 23' thereby clamping the washer 23 against the end 24 of the sleeve operating member 25 and said end 24 against the cowl 9, and also clamping the outer end of the sleeve II against the friction washer 22.

Thus, as will be seen, the sleeve I I normally is frictionally locked to the cowl 9 by engagement of washer 23 with end 24 and end 24 with cowl 9, the elbow is similarly locked to the sleeve II by engagement of the enlarged end I3 of the latter with the washer 22 and the washer 22 with the countersink I4. However, as will also be clear, said sleeve II is movable inwardly of the cowl 9 along the housing I5 against the cushioning action of the member 2I and spring 26 to break the friction at the point of engagement of the parts above enumerated, whereby the elbow 5 may be rotated through the medium of the housing I5 to position the unit I as desired.

To break the frictional engagement of the parts, the sleeve operating member 25 is extended along the housing I5 and provided adjacent to the handle bar I8 with a right-angularly related end 28 apertured, as at 29', to slide on the housing I5, and a hand grip 29 is provided on the handle bar I8 which is pivoted to the latter, as at 38, and has a notched end 3| straddling said end 28 of the member 25, the arrangement being such that the driver grasping the handle bar I8 and the hand grip 29 may by so doing manipulate the latter to move the member 25 inwardly and thereby slide the sleeve II in the cowl 9 to break the frictional engagement between the end 24 of member 25 and the cowl 9 and also between the end I3 of sleeve II and the washer 22.

The unit I is adapted to be releasably retained in horizontal position by means of a coil spring 32 suitably secured to and extended from a resilient suction cup 33 adapted to be attached to the hood 34 at any suitable point thereon for the insertion of the section 2 of vunit I between convolutions of the spring 3 2, as shown for instance in Figure 3.

As shown in Figure 1, in dotted lines, by mounting the elbow 5 on the cowl S! in the manner specified the unit I may be swung from a substantially horizontal, out-of-the-way position, alongside the hood 34 into an upright position alongside the left corner of the body I0 proper whereby said unit is also located in an out-of-the-way position for use. Obviously, the unit I may be swung into different positions as desired.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention without further explanation.

Manifestly the invention, as described, is susceptible of modification without departing from the inventive concept and right is herein reserved to such modifications as fall within the scope of the subjoined claims.
