RADIOANTENNA.

Application filed March 3, 1924-. Serial No. 696,539.

This invention relates. to a radio antenna or aerial, one object of which is to pro vide means whereby the strength of the signals will be increased by small bodies of metal on the antennae at intervals.

Another object of the invention is to pro vide means whereby the eii'ective area of the antenna will be increased to amplify the strength of the si nals by providing a series of additional. wires hanging from the an terms. at intervals.

Another object of the invention is to provide means whereby the sensitivcness of the antenna to incoming signals, will be increased where it happens that the antenna may be installed in the least effective direction the wires depending from the main wire each having a series of horizontal wires extending therefrom.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

Fig. l is a perspective view of a complete antenna installation,

Fig. 2 is a side elevation of one of the tinished depending cat-whisker wires,

Fig. 3 is a view on a large scale showing the way the wires are tied together at their lower ends before soldering,

Fig. 4c is a side elevation of a relay coil used in the place of the soldered metal lumps.

The numerals l and 2 indicate poles on which the antenna is supported, ropes 3 and 4t passing over pulleys 5 and 6 being used to raise and lower the antenna 7 when desired. Insulators 7' and 7 are used to connect the wire 7 to the ropes and the ropes are tied on the cleats 3, 4 when the aerial is up.

The antenna wire 7 is connected, to the receiving set 8 (or it may be that the aerial is used for sending), by means of the usual wire 9, and the set 8 has the usual ground wire 10. Stranded wires are preferred as giving a better electrical effect than single wires, but a single wire may be used to producc the efiects of this antenna, if the soldering is carefully done, and if the cat whiskers are made of line wire.

Secured on the antenna wire at intervals, are a series of small lumps of solder, tin,

bismuth or other suitable conducting metal, said lumps being applied about every two feet. The object of providing the small lumps of solder along the stranded wires of the aerial is for the purpose of acting as arelay and as an accumulator of the oscillating energy from the sending aerial to the de tector aerial whether a crystal or vacuum tube. A further object of the soldered lumps is to prevent any separation of the stranded wires of the aerial.

About every fifteen feet there is provided a depending wire 12 which is soldered to the main wire 7 of the antenna.

Lumps of metal may be placed on these wires, every two feet if desired, and they may be made from t to 10 feet long as may be required for the particular work to be carried out.

The lower ends of the depending wires 12 are then unwound for about 6 to 8 inches, or more, if desired. The wire ends are then carefully tied in knots where the unwinding stops, the ends being bent out horizontally in all directions. When the wires have been bent out horizontally the knots are soldered, as shown at 13, Fig. 3 and the aerial is ready for use, in receiving signals, musical and me chanical sounds, as well as the speech of the human voice.

Experiments carried out with such an aerial show that the amperage, or quantity of the etheric forces entering the mechanism of the radio receiver from the radio transmitter are greatly increased, and that the quality of the radio signals is much improved over the ordinary form of single or multiple wire antennae.

In Fig. 4 there is shown a section of wire on which there is wound a small coil at intervals such as may he Found necessary. These coils, indicated at 20, are wound on the antenna wire at intervals of 2 feet or more, and may or may not be insulated, but their ends are soldered to the main antenna Wire 21. These coils consist of very fine wire and may contain several feet of wire each.

The coils 20 act as accumulators of the oscillating energy from the sending aerial it having been proved that the area of the conductor is a factor in its ability to collect the desired radiations.

What I claim is as follows, but modifications may be made in carrying out the invention shown in the drawings and in the above Hit! "Lil

particularly described form thereof, Within the purview of the invention as defined by the annexed claim: t

A radio aerial comprising a stranded wire 5 antenna, a'series of'solicl metal lumps secured to said stranded Wire in spaced relation, and a series of depending stranded Wires spaced apart attached to said stranded Wire havinw the lower ends of said depending Wires Bent to radiate in a horizontal 1 plane.

In testimony whereof my hand this 25 day of February, 192 i \VILLIS EUGENES EVERETTE.

I have hereunto set A. D.
