Original application filed November 18, 1905, Serial No. 288,032. Divided and this application filed Demember 31, 1906. Serial No. 350,258. 1
To all whom 'it may concern: 7
Be it known that I, SnwALL GABOT, a citizen of the United States, and a resident of Brookline, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Space Telegraphy, of which the following is a specitication. My invention relates to the art of transniitting intelligence from one station to another by means of electromagnetic waves without the use of wires to guide the waves shall have the advantages hereinafter set forth.
My invention may best be understood by having reference to the drawing which accompanies and forms a part of this specification and which illustrates one of the many possible embodiments of my invention, together with one of the ways in which it may be employed in a space telegraph transmitting system.
in the figure, the circuit S C I, is a sonorous circuit which includes the multiple series spark-gap S, the condenser C and the primary l of the oscillation transformer M, whose secondary 1 is included in the elevated conductor system V I E, said system being earthed at E, either directly or else through a receiving system, as more fully described in my Patent No. 840,908, granted I January 8, 1007, on my application Serial 40 No. 288,032, filed November 18, 1905, of which the present application is a division.
The aforesaid sonorous circuit is energized by the alternator A, or other suitable source of vibratory ielectromotive force and the transformer M, whose primary and secondary windings are shown respectively at I, and 1 may be interposed between said alternator and said sonorous circuit.
K is a key for controlling the current in the circuit of the primary of the transformer M inaccordance with the signal to be transmitted. The transformer M may be earthed as shown at E. r
-A preferred form of discharger or-sparkgap is shown at S and consists of a multipleseries spark-gap. The electrodes of said multiple-series gap are formed preferably of zinc, although any suitable material may be employed, and if of zinc, they may be formed into the desired shape. by working an ordinary battery zinc by means of a hand-tool. The electrodes Z are placed as'shown, with their ends resting upon the insulating mem bore 38. As indicated, one terminal of the gap is connected to one terminal of the secondary I, and to the condenser C, while the other terminal is connected to the second terminalof said secondary, and to the earth connection E. In order to regulate the number of the members Z emp oyed in the multiple series spark-gap, I may employ a rod 40, provided at one end with a handle 41 of insulating material and at the other with a spring-contact 42, said rod being mounted to slide in the standard 39.
The advantages of series spark-gaps are well known, having been set forth in U. S. Letters Patent to J. S. Stone No. 708,000, and elsewhere; but so far as I am aware, a multiple-series spark-gap has not before been used as a discharger for the condenser of a sonorous circuit. Such gap is highly advantageous for the purpose of aii'ording as large a number of short paths for the spark as may be desired, and thereby reducing the resistance to electrical oscillations initiated in the sonorous circuit by the first discharge of the condenser across the gap. The advantages of using zinc are that it absorbs the oxygen from the nitrous acid created by the spark discharges and fixes it, and also that its vapor is non-conducting, so that a gap having zinc electrodes is a nonarcing gap.
1 do not wish to be limited to the exact form of construction herein described, inasmuch-as it will be obvious that many modifications may be made therein without departing from the principle of my invention.
I claim:
1. In a space telegraph transmitting system, the combination, with a sonorous circuit, of a multiple-series spark-gap and means for including any desired number of the electrodes thereof insaid circuit.
2. In a space telegraph transmitting system, the combination, with a sonorous circuit, of a multiple-series spark-gap having its electrodes formed of a non-arcing metal and means for including any desirednumber In testimony whereof, I have hereunto of said electrodes in said circuit. subscribed my name this 29 day of December 10 3.
