TELEVISION ANTENNA CONSTRUCTION Filed March 14, 1950 JNVENTOR. Mfg/MEL .c' )FOJEWYZWL Patented Apr. 1, 1952 UNITED STATES PATENT OFFICE Claims.

This invention relates to a television antenna construction.

It is an object of the present invention to provide a television antenna construction wherein the antenna parts can be wired upon the antenna by simple connecting of the lead-in wires to the different portions of the antenna parts and wherein by a simple switch lever the hook-up for the different antenna parts can be changed.

It is another object of the present invention to provide a television antenna construction wherein the end rings provide, with the various connecting members for supporting the rings, a substantially cone-shape structure and wherein the rings are of a diameter substantially equal to the length of the members connecting the rings with the center structure of the antenna construction and wherein the rings are formed of semicircular parts insulatingly connected together to provide a complete ring.

Other objects of the present invention are to i provide a television antenna construction which is simple, inexpensive to manufacture, has a minimum number of parts, easy to assemble, easy to connect and disconnect for the different arrangements of the antenna parts in the antenna system, compact, has a single center block, and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. l is a perspective view ofthe antenna construction embodying the features of the present invention.

Fig. 2 is an enlarged elevational view of the antenna with the lead-in wires connected to the parts on but one side of the construction.

Fig. 3 is a fragmentary elevational view of the center structure with the lead wires connected respectively to the opposite sides of the antenna.

Fig. 4 is an elevational view with the switch arm lowered to bridge the antenna parts on the opposite sides of the structure.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 3.

Fig. 6 is an enlarged sectional view taken generally on line 6-6 of Fig. 2.

Fig. 7 is a fragmentary perspective view of a portion of the antenna parts showing the hollow piping which is used to provide the semicircular member and the longitudinally extending supporting members.

Referring now to the figures, It) represents a supporting post to which there is secured a block of central structure II by means of U-bolts' l2 having nuts I3 thereon. This block II extends to the opposite sides of the post II). A cage is connected to each side of the block I I. Each cage comprises a circular part I4 formed of two arcuate sections I5 and I6 insulated from one another at I! and I8. The section I5 has longitudinally extending members I9 and 20 which are connected respectively to the opposite sides of the block by bolt means 2|. Longitudinally extending

members

22 and 23 extend from the arcuate section I6 to the block II and are connected respectively upon the opposite sides thereof by bolt means 24. The arcuate sections and the members, which extend longitudinally to support the arcuate sections, are hollow or tubular, as shown clearly in Fig. 7. The ends of the longitudinal members are flattened, as indicated at 25, Fig. 7, so as to fit flush upon the face of the block II. It will be apparent that each cage is of the same construction. While the numerals have been applied to the cage at the left side of Fig. 1, it will be understood that they equally apply to the cage at the right side of Fig. 1.

Pivoted upon one of the bolts 2| is a bridging arm 2-6 having a notch 21 therein to receive the bolt at the opposite end of the block I I whereby to connect together the two top sections of the cages. This arm 29 will thus put into circuit relation the top sections of the two cages. This arm is shown connected in Fig. 4.

The lead-in wires can be hooked up to the different arcuate sections in any number of dif-- ferent ways. As shown in Figs. 1 and 3, cables 3| and 32 are connected respectively to lower section I8 of one cage and upper section I5 of the other cage. As shown in Fig. 2, both cables are connected to the one cage and the switch arm 26 is lifted. Cable 3| in this instance: will be connected to the upper section I 5 of the one cage and cable 32 will be connected to the lower section I6 of the same case.

With the switch arm 26 bridging the bolt means 2|, as shown in Fig. 4, cable 3| will be connected to the upper sections of the two cages while cable 32 will be connected to the lower section of the left hand cage.

These different wiring connections can be made at the time the television set is installed and to give the best reception of the set for the particular locality.

The rings are of a diameter equal to the length of the longitudinally extending members.

It should be apparent that there has been proside of the central structure II, in the manner shown particularly in Fig. 3. Thereis'accordingly provided on the arm 26 a second notch 27". A second switch arm 34 is provided at the right side ends of the block whereby to place the sections otthe cages on the opposite sides of the block in circuit relation.

3. An antenna construction comprising a post, an insulating block secured to the upper end of the post and extending respectively to the opposite sides thereof, a cage connected to the opposite sides of the block, and each cage com prising a circular ring and longitudinally extending members connected between the ring and the block, bolt means extending through the block to secure the longitudinal members thereto, and a bridging arm adapted to extend between the bolt means at the opposite ends of the block of the structure and it also'has spaced

notches

35 and 35. When the switch arm 34 is extended vertically, its notches will be connected between the bolts at one side of the structure, Fig. 3.

'Thefar'm 34 can also be extended acro'ssthebot- 'tom of the structure the same as'the arm 26 is extended across the top of the structurewhereby the connection can be made between the lower halves or arcuate sections [6 of the respective circular parts 14 of the cages.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

I claim:

1. An antenna construction comprising a post, an insulating block secured to the upper end of the post and extending respectively to the oppolsite sides thereof, a cage connected to the opposite sides of the block, and each cage comprising a circular ring and longitudinally extending members connected between the ring and the block, bolt means extending through the block to secure the longitudinal members thereto, the said ring comprising two arcuate sections, and

two of said longitudinal members connected to each section, the longitudinal members of the sections being vertically spaced upon the block, the arcuate sectionsof'thering being insulated from each other.

2. An antenna construction comprising a post, an insulating block secured to the upper'end of the post and extending respectively to the opposite sides thereof, a cage connected to the opposite sides of the block, and each cage comprising a circular ring section with a plurality of arc sections insulated from each other and longitudinally extending members connected be.- tween the ring and the block, bolt means extending through the block to secure the longitudinal members thereto, and a bridging arm adapted to extend between the bolt means at the opposite whereby'to place the cages on the opposite sides of the block in circuit relation, and each of the -cages having their rings formed of arcuate sections insulated from one another, two longitudinal members extending from each of said sections, the longitudinal members of one section being vertically spaced from the longitudinal members of the other section.
