Specification of Letters Patent.
Patented May t3, 1919).
Application filed January 10, 1913. Serial Ito; 270,556.
To all whom it may concern.-
Be it known. that I, JAMns Harms Roe-Ens, a citizen of the United States, residing at Hyattsville, in the county of Prince Georges and State of Maryland, have invented new and useful Improvements in Wireless Signaling Systems, of which the following is a specification.
My invention relates to radio signaling, and has for its object the provision of an improved system for use in connection with vessels, particularly submarines.
The invention comprises the employment of an insulated radio conductor or antenna suitably mounted upon the submarine but insulated therefrom except at the outer ends where it is in electrical connection with the metallic body of the vessel. Electromagnetic wave sending and receiving instruments are arranged to be associated with the said conductor at a point intermediate its ends, in any suitable manner.
The invention consists in the novel system, and arrangement of apparatus and circuits hereinafter described and claimed, and shown in the accompanying drawings, in which drawings- Figure 1' shows a submarine vessel equipped with the invention, a portion of the vessel being in section, and the wireless apparatus and circuits for receiving messages being diagrammatic;
Fig. 2 is a diagrammatic view of conventional sending apparatus and circuits for use with the system of Fig. 1 for the purpose of sending signals.
Referring to the drawings, 10 indicates the metallic hull of a submarine vessel, which may be of any type or construction, 11, 11 indicate an insulated radio conductor so mounted as to be electrically insulated from the vessel and the water except at its outer ends where the portion 11 is connected at 12 to the bow of the hull and portion 11 is connected at 13 to the stern of the hull.
Associated with the radio conductor, preferably. at some point between its ends,
are electromagnetic signal instruments. As
shown conventionally, receiver 14:: is in circuit with winding 15 of an inductive coupling of which the other winding 16 is con nected to the radio conductor 11, 11. 17 is the usual detector, which may be an audion,
and 18 and 19 are the usual condensers.
Sending instruments and circults for use with the system are shown in Fig. 2, whereininstruments 20 is a source of current, 21 a key, and 22 a spark gap in an oscillating circuit which includes winding'lo of the coupling. This sending apparatus is of course on the vessel.
Any desired electromagnetic wave signal may be employed, those shown being merely illustrative.
From the foregoing it will be seen that the radio conductor constitutes with the electrical connection through the vessel a loop oscillating circuit which will oscillate in response to electromagnetic waves being received, or set up bythe sending instruments. A suitable tuning condenser 23 is provided to tune this oscillating circuit to the proper frequency. It will also be observed that the radio conductor is carefully insulated throughout its length between its ends, so
that it cannot make electrical connection with the vessel, or the water when the submarine is submerged.
While l" have described a specific embodiment of the invention, this is only by way of illustration, and it will be understood that modifications may be made without departing from the invention. For instance, the electrical connec'ion between the ends of the radio conductor may be made by a metallic conductor other than the hull of the vessel.
I claim:
/ 1. The combination with a vessel, of a radio conductor extending longitudinally thereof but insulated therefrom and from the water except at its ends which make electrical connection with the vessel, an electrical connection between said ends of the radio, conductor through said vessel, and electromagnetic signaling instruments associated with said radio conductor at a point between its ends.
2. The combination with. a submarine vessel having a metallic hull, of an insulated radio conductor extending longitudinally thereof and connected electrically at its ends with said hull, whereby a loop oscillating circuit is provided, and electromagnetic signaling instruments associated with said looped oscillating circuit.
3. The combination with a submarine vessel having a metallic hull, of an insulated radio conductor extending longitudinally thereof and connected electricallyat its ends are signaling instruments associated with said looped oscillating circuit.
4. The combination with a submarine Ves sel having a metallic hull, of an insulated 5 radio conductor extending longitudinally thereof and connected electricallyrat its ends with said hull, whereby a loop oscillating circuit is provided, electromagnetic signal instruments associated with said radio con; ductor between its ends, and a tuning con- 10 denser in circuit with said conducto In testimony whereof I have hereunto set my hand.
JAMES HARRIS ROGERS.
