TELESCOPING TELEVISION MAST Filed Aug. 31, 1950 2 SHEETSSHEET 1 Fig.

I 21 ventor John. 5. Anderson WWW fi amggg March 24, 1953 J. s. ANDERSON TELESCOFING TELEVISION MAST Filed Aug. 31 1950 2 SHEETS SHEET 2 Inventor John 5. Anderson Patented Mar. 24, 1953 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to an antenna mast structure and more particularly to a telescoping or collapsible antenna mast for installation on an automotive vehicle, which mast is especially adapted to be used for television service and repairmen and. salesmen in demonstrating their product.

An object of this invention is to provide an antenna mast for television signals or the like which -may be readily installed on the bumper or running board of an automotive vehicle such as a passenger car or pick-up truck so as to enable a salesman to promote and demonstrate the television sets which he may be promoting.

A further object of this invention resides in the provisionor" a telescoping antenna mast which while being rigidly supported on an automotive Vehicle, may also be collapsed to a relatively small compass.

Still another object of this invention resides in the provision of a television mast which has means associated therewith for supporting such in ground engagement.

A further object of this invention resides in the provision of the clamping means for supporting a transverse rod on the top of an automotive ve hicle.

Still further objects of the invention reside in the provision of a telescoping antenna mast that is strong, durable, highly efiicient in operation, simple in construction and manufacture, capable of being collapsed to a relatively small compass, and which is relatively inexpensive to manufacture.

These, together with the various ancillary objects of the invention which will become apparent as the following description proceeds, are attained by this antenna mast, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a side elevation a1 view showing the antenna mast comprising the present invention in a collapsed position;

Figure 2 is a partial top plan view of the antenna mast as shown in Figure 1;

Figure 3 is a side elevational view showing the antenna mast comprising the present invention in an upright position;

Figure 4 is an enlarged elevational view of a portion of the device with parts thereof being shown in section to show other parts in greater detail;

Figure 5 is an enlarged vertical sectional view as taken along the line 55 in Figure 3;

Figure 6 is an enlarged elevational detail show- 2 ing the support members for holding the upper tubular components of the invention in a horizontal position when the television antenna mast is collapsed;

Figure '7 is a enlarged sectional view showing the ground engaging member comprising one element of the present invention, as taken along the line 'l--l in Figure 8; and

Figure 8 is an elevational view of the ground engaging member as illustrated in Figure 7.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates an automotive vehicle having a bumper l2 on which the invention is adapted to be secured. This invention includes a sleeve member l4 having ears l6 and I8 extending therefrom to which ears there is pivotally connected clamp members 2!) and 22 which are adapted to be bolted together as at 24 so as to embrace the bumper l2.

The sleeve member 14 is provided with a transverse ap-erture in which a locking pin 26 is adapted to be positioned.

Slidably supported within the sleeve [2 and upwardly extending therefrom is a lower tubular member 28 adapted to engage the locking pin 25. Suitable stubs 30 are formed on the tubular member 28 in order that the same may be rotated for a purpose presently seen.

Secured to the lower tubular member 28 is a stop member 32 on which there is positioned a collar 34 having a support bracket 36 attached thereto. Also attached to the collar 34 are cars 40 to which there is pivotally attached one end of a brace bar 42 which is attached to a transverse bar 44 bolted to upwardly extending members 46 and 48 which are welded or otherwise attached to clamp members 50 and 52, each of which clamp members are provided with an end portion as indicated at 54 and 56 which are adapted to embrace and engage the rain gutters of the automotive vehicle [0. A central member 58 is bolted into clamp-like engagement as indicated at 60 and 62 with the members 50 and 52.

A coupling member 64 is secured to the top of the tubular member 28 for threaded engagement by an upper tubular member 66 which has slidably received therein another tubular member 68 which is held by a locking pin 10 in a vertically extended position. A further tubular member 12 is slidably received within the tubular member 68 and is held in position by the locking key 14. Swivelly mounted at the top of the tubular member 12 is a ring 16 to which guy wires 18 are adapted to be attached for additionally supporting the television antenna mast,

In order to erect this television antenna, mast on the car or truck it is first necessary to remove the bolts on the ears ll] and on the cars it and then swing the tubular member 28 downwardly. Then the tubular member 66 is screwed into threaded engagement in the coupling 54 and the guy or guide wires are snapped into the ring it. The antenna is fastened to the top or section 52 and then the entire assembly is swung up into position and the heretofore removed bolts are again positioned in place. It is then possible to climb up the steps 30 and standing on the brace bar 42 it is then possible to raise the telescope or tubular section and position the locking keys or pins in place. Then, the guy wires may be secured in their desired position to rigidly support the device.

It may be necessary or desirable to permanently afiix the television mast to the ground so that the automotive vehicle may be used without the television antenna thereon. To do this, it is merely necessary to remove the pin 2S while supporting the television antenna above the level of the ground so that the ground engaging coupling member 83 will be threadedly engaged on the bottom end of the member 28. Suitable prongs 82 and t l are provided for engagement with the ground. Then, the sleeve is will be allowed to slide up the tubular member 2% or be elsewise removed from the mast leaving the television antenna mast in position in the ground.

Since from the foregoing the construction and advantages of this telescoping mast for television or other high frequency antenna is readily apparent, and further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifications and equivalents may be readily resorted to which fall within the scope of the appended claims.
