BADIOSIGNALING SYSTEM.
Specification of Letters Patent. Patented Aug. 16', 1921.
Original application led Hay 2, 1917, Serial No. 165,875. Patent No. 1,349,103, dated August 10, 1920. Divided and this application file d March 8, 1920. Serial No. 364,224.
To aZZ 'whom it may concern.'
Be it known that I, JAMES HARRIS ROGERS,
4 a citizen of the United States, residing at Hyattsville, inthe county of Prince Georges and State of Maryland, have invented certain new and useful Improvements in Radiosignaling Systems, of which the following is a specification.
My invention relates to radio signaling or the sending and receiving of signals through space by means ,of electromagnetic waves, and it pertains particularly to the disposition of the radio conductor or conductors.
In the course of my experiments I have discovered that grounded radio conductors or antennae are highly eilicient when disposed horizontally or substantially parallel to the surface of the earth, and surrounded by or inclosed in a uniform metallic screen practically throughout their length, but insulated therefrom. The advantages of long prostrate (as distinguished from erect) antennae are thus obtained and the objectionable effects of certain forms of static conditions are eliminated.
e invention as applied to the surface of the earth where there is land is described, illustrated and claimed in my pending original application Serial No. 165,875 filed May 2, 1917, (now Patent No. 1,349,103), of which the present application is a division. In said original application, the term surface of the earth was used to designate the surface where there is water as well as where there is land, and the invention is therefore equally applicable to boats or vessels, particularly submarines, lon which it is operative whether afloat or submerged.
The invention consists in the novel construction and arrangement of apparatus and parts thereof for sendingand receiving radio signals hereinafter described and claimed, and illustrated in the accompanying drawings, in which drawings- Figure l is a diagrammatic view of a boat or vessel, such as a submarine, equipped in accordance with the invention, receiving instruments being shown associated with the antennae; and
of sending instruments which may be substituted for the receiving instruments for transmitting signals.
Referring to the drawings, 10 indicates the signal instruments, which in Fig. 1 are Fig. 2 shows a conventional arrangement those for receiving signals, while in Fig. 2 the instruments. for sending signals are shown. In Fig. 1, 11 is a detector of any type, preferably an audion, 12 a telephone, and 13 and 14 the usual condensers. Any desired type of instruments and arrangement of connecting circuits may be employed.
In Fig. 2 suitable sending instruments are conventionally shown. These comprise a generator 15, transformer 16, spark gap 17, condenser 18 and key 19.
. The above mentioned instruments are well known in the art of radio or magnetic wave signaling, and need not be further described.
2O and 21 are two antennae extending in different directions from the signal instruments, and are shown associated with these instruments by inductive coupling, as coils 22 and and 23 of a transformer. These antennae may extend in opposite directions, and in order to attain maximum eiiiciency, arrangement may be made so that they may be disposed in a line at right angles to the wave fronts when receiving.
The antennae are each inclosed in a metallic screen shown as a metal pipe 24 in which the antenna is mounted by spacers or disks 25 of insulating material, such as porcelain, clay, fiber or the equivalent, so that while each antenna is inolosed substantially throughout its len th by the metallic screen it is insulated t erefrom. At the outer end, or end away from the instruments, each antenna 20 and 21 is connected to plates 26 and 27, respectively.
The length of each antenna may be selected to suit the condition under which each system is to work, and may be several hundred feet or more. The pipe or screen may be of iron or other metal suitable to accomplish the purpose, and serves to protect the antenna from certain static conditions which would, or might, interfere with the sending or receiving of signals.
In the present embodiment of the invention, it will be seen that the antennae with appropriate screens are mounted within a vessel indicated at 28, this vessel being shown as a submarine. The screens 24 are preferably extended through the sheathing or hull, so that each antenna is inclosed substantially throughout its length within the vessel. The ground plate 26 at the forward end of the vessel is preferably pivotally mounted at its forward edge' on brackets 29, 30, so' as to swing freely with the movement of the vessel, but is insulated therefrom, as shown diagrammatically at 31, 31. This antenna 2O 1s connected to late 26 in any suitablemanner. Ground p ate 27 is similarly mounted on brackets 29', 30', at the stern of the vessel, and is connected to antenna '21. These plates may be mounted in any other suitable manner.
In the use of' the invention, the pipe or screen is preferably filled with oil such as is ordinarily used- 1n transformers, for the purpose of preventing brush discharge.
The details of construction and arrangement of the `pipe or screen containing the spacing elements, the antennae, and the oil, are as illustrated in the application of which the present application is a division, and it is therefore thought that further illustration in the present case is unnecessar 1i will thus be seen that I have provided a vessel, such as a submarine, with radio signal receiving and sending apparatus associated with a conductor extending longitudinally thereof, substantially the full length of the vessel. It will also be observed that this conductor with which the signal instruments are associated is inclosed substantially throughout its length within said vessel, and therefore when the vessel is a submarine, and is running submerged, the conductor is insulated lfrom the water substantially throughout its length.
In accordance with the present statutes I have described what I now believe to be the best embodiment of the invention, but I do not wish to be understood thereby as limiting myself or the scopeof the invention, as many changes and modifications may be made without departing from the spirit of the invention, and all such I aim to include in the scope of the appended claims. For instance, each antenna is shown as a single wire or conductor, posed of multiple conductors.
Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:
1. The combination with a vessel having -a metallic hull, ofv an antenna extending substantially horizontally and inclosed substantially throughout its length within said hull, and electromagnetic wave signal instruments associated with said antenna.
