To all whom it may concern:
Be it known that we, James H. Rogers and Henry H. Lyon, citizens of the United States, residing at Hyattsville, in the county 5of Prince Georges and State of Maryland, have invented new and useful Improvements in Wireless Signaling Systems, of which the following is a specification.
Our invention relates to the transmission 10of electrical impulses or oscillations to a distance, primarily for the purpose of conveying intelligence, and it pertains to means for both sending and receiving.
In systems of wireless sending and receiving15 now in general use one or more conductors or capacities are employed disposed above the surface of the earth, which conductors or capacities serve to radiate or receive the impulses in the sending or receiving20 of messages. Such elevated conductors are costly to erect and maintain, as to obtain efficiency and long-distance transmission it is necessary to have them at considerable distance above the surface of the earth. 25This necessitates expensive towers and masts, and moreover both the conductors and the towers or masts are exposed to weather conditions—wind storms, lightning, snow and ice—which often impede or 30entirely prevent the operative use of the system. We are aware that it has been proposed also to employ a conductor elevated above the earth in connection with a buried conductor.
35Our invention has for its principal object the provision of a system not subject to the above objections; a system in which the communication, both sending and receiving is clear and effective; in which the communication40 is selective and the direction of transmission may be readily determined; in which multiple transmission may be effected; and in which the sending and receiving of messages to and from stations on land and on 45water may proceed independent of weather conditions.
We have discovered that signals can be sent and received with great facility by the employment of wires laid directly on, or 50buried in, the earth and in intimate contact therewith substantially throughout their length and parallel to the surface.
The invention also consists in the novel features and combinations of circuits and apparatus in the wireless signaling system55 hereinafter described and claimed, and illustrated in diagram in the accompanying drawings, in which—
Figure 1 is a system in which a single antenna is shown buried beneath the 60surface of the earth, the signal instruments being those of a receiving station;
Fig. 1a shows the system with the antenna lying along the surface of the earth in intimate contact therewith substantially65 throughout its length, the signal instruments being omitted;
Fig. 2 is a view similar to Fig. 1 showing two antennæ extending in opposite directions;70
Fig. 2a is a view similar to Fig. 2, the antennæ being shown lying along the surface of the earth in intimate contact therewith substantially throughout their length instead of being buried beneath the surface,75 and the signal instruments being omitted;
Fig. 3 is a view similar to Fig. 1 showing tow antennæ extending in opposite directions;
Fig. 3 is a view similar to Fig. 2, but with the instruments of a sending station;
Fig. 4 is a diagram showing in plan a plurality of antennæ extending outwardly in80 different directions;
Fig. 5 is a similar view, including also switching means for making the proper connections;
Fig. 6 shows the invention applied to the85 earth’s surface upon the water;
Fig. 7 is a view similar to Fig. 6, showing an additional feature of the antenna;
Fig. 7a is a detail of the form shown in Fig. 7;90
Fig. 8 shows the antenna supported on the surface of the water;
Fig. 9 shows the antenna on the surface of the earth below the surface of the water; and 95
Fig. 10 is a view similar to Fig. 2, showing the entire installation underground.
Referring to the drawings, signal instruments are indicated at 10, and in Figs. 1 and 2, 11 is a detector of any type, preferably an audion, 12 a telephone and 13 and 14 are the usual condensers. Any desired type of 100instruments and arrangement of connecting circuits may be employed.
The surface of the earth is indicated at 15,
