' AERIAL APPARATUS;

A lication filed march '7, 1927. Serial no. 173,864.

This invention relates to an aerial appa ratus designed for use with aradio receivin set. It is of a type which may be containe within a housing easily portable and installable at any desired point interiorly of a building.

The present apparatusincorporates cer tain improvements in'the direction of siinplicity and compactness. It may conveniently be enclosed withina protective housing havinga location adjacent to or remote from, a receiving set. In addition','its antenna is comprised of a copper wire strung back and forth between two head plates,and

therefor partly broken away;

Fig. 2 is a transverse section through the various wire stringings and rods forming the antenna; 1 r s I Fig.- 3 is a fragmentary detail in section showing the mounting for one wireand rod; and

connection at one end of the antenna. The-present apparatus maycompr1se a base Aliavingupturnedmarginal edges 5 forming a shallow enclosure for the recep v tion of the lower edges of a protective cover B having. a box-like structure. With the cover 'set', in place upon the base, acom pletely protected compartment is provided. As by means of screws or hooks, not shown, the cover may be removably secured to the base. All of theparts just described maybe made of any suitable material' finished as desired.

Secured to the base in spaced-relation its several marginal edges, is a horizontal plate 6 to the opposite ends of which are connected upstanding headplates7 and 8 made preferablyfrom some insulated mate- Fig. 4.- which is a similar view showsthe.

rial. Each head plate is formed with a plurallty of aligned holes 9.and 10, the latter being the larger. The hole. shown near the ,lower' left corner of the proximate head plate 7 in Fig. 1 is'of the larger size to accommodatean eye'bolt 11 (see Fig. 4) which is desirably fastened in place by nuts 12 which bear upon oppositesides of the head plate. The bolt is disposed with its eye for convenient connection with one end of a copper wire 14 which is extended to the other head plate 8. This wire passes through an opening 9 therein in alignment with the eye bolt, and. then around upon the outer side of the head plate to an adjacent opening through-which it is strung back to the head plate 7.- In like manner this wire for its entire length is strung back provide a mounting'therefor. s

In the form shown the wire stringings are located relatively close to the edges of the head plates.- The endof the wire opposite to that which is connected with the eye bolt may be joined to .a terminal 15 having-an eye through which is received one end of a conductor rod l6, preferably of brass. These rods, of which several are shown,are all alike, as are also their mountings in the two head plates. The ends of each rod 16, as

shown in Fig; 3, are'threaded to receive a pair of nuts 12 arranged in each instance on- 0ppos1tesides of the proximate head thereupon when'suitably adjusted. In this mannerthe rods are secured against movement, as are also the head plates which form mountings therefor.

' 'As' each rod is an independent unit, Iprovide between them serial connections adjacent outer sides of the two head plates. For.

'85 plate .and adapted to bear with pressure,

this purposeyl may employ link bars I? having. at their opposite ends eyes which fit around the ends of the rods to be connected.

After the nuts 12 are tightened in place,

these link bars, :as well as the terminal '15,

are made secure so as to connect up in series the wire 14 as well as the several bars 16.

The construction thus-far described is one which provides an antenna-consisting of a continuous'wire strung back and forth betwee'n'the two head plates in connection with 70 and forth between the two head plates which a plurality of bars interconnected in series fashion. One end of the antenna is constituted by the eye bolt which, by means of the associated nuts 12, is adjustable to take up slack in the wire. A flat copper bar 18 formed preferably with eyes at each end, connects this bolt with a binding post 19, the bar extending first downwardly from the bolt and then horizontally to the post which may be arranged adjacent one edge of the base A. A similar bar 20 having connection with a second binding post 21 extends also to the opposite antenna end formed by one of the rods 16.

An aerial apparatus so constructed constitutes a unit which is convenient for handling and installation, it being understood, of course, that suitable conductors are to be extended from one of the binding posts to the antenna connection of the receiving set, and that another connection, if desired, is to be extended from the other post to the ground. In the exemplification shown, the parts forming the frame on which the an tenna is carried are of light construction without sacrifice of sturdiness. This is due in part to the character of the two antenna components used, viz, the wire which tends to draw the two head plates together and the rods which serve to hold them apart. In addition, the arrangement by which the wires are grouped around the rods is one which conduces to facility in assembly. This results from the fact that the frame can be completely set up and made rigid by the use of the rods alone after which the wire can be strung back and forth without requiring further support for the head plates. It is not necessary, according to the construction shown, to resort to solder connections at any point inasmuch as the several link bars may be preformed to fit accurately in their intended plates.

In the operation of the present apparatus I have found that very satisfactory results are obtainable. By'combining in an antenna a wire component formed of copper strands in the usual way with a number of connected brass bars having a cross sectional size which is relatively large, I provide what is the equivalent of an aerial having a length considerably greater than the aggregate of the parts which are extended between the two head plates. Also because of the fact that the conductivity of brass rods is slower than that of the copper strands, the flow of current is somewhat retarded, thus reducing to a large extent the interference which normally results from static.
