RADIOSIGNALING SYSTEM.
Specification of Letters Patent. i Patented )I 30 1922 Application filed .Tune 16, 1917. Serial No. 175,118.
To all whom it may concern Be it known that I, LEE on FOREST, a citizen of the United States,-residing at New a radio signaling system employing an oscillion whichis simple in structure, eflicient in operation, and economical of manufacture.
Further objects of my invention will appear more fully hereinafter.
The invention consists substantially in the construction, combination, location, and relative arrangement of parts, together with circuits associated therewith, all as will be more fully hereinafter set forth as shown by the denser 7 to. the filament electrode 8 of the.
oscillion 6. The plate electrode 5 is also connected through, impedance coil 9, inductance 10 to the source of current illustrated at 11 to the filament 8 as shown. The filament 8 is heated by the battery 12 through the variable resistance 13 in the usual well known manner. The special purpose of my present invention is to provide what I term a tickler circuit from the grid electrode or electrodes, as the case may be, to;the filament 8, preferably with a high resistance 14 to form a leak path therefrom'to the filament. Preferably the high resistance is shunted around a condenser 15 as shown." This tickler circuit from the grid to the filament through the leak path. is inductively associated with inductance 2 of the antenna earth system 1 to 4. lVith this arrangement I find that the efficiency of-the transmitting sys-,-
tem is greatly increased.
Having now set forth the olnects and nature of my invention, and having shown and described one embodiment thereof, what I claim as new and useful. and of my own 111- vention, and desire to secure by Letters Patent,1s,-
1. The combination with an antenna-earth system including an inductance and a capacity in series, of an evacuated vessel contaming a hot and a plurality of cold electrodes, a conductive connection between said hot electrode and one side of said capacity, a' conductive connection between one cold electrode and the other Side of said capacity,
and a circuit between another cold electrode and said hot electrode, inductively associated with said inductance of said antenna-earth system.
2. The combination with an antenna-earth system including an inductance and a capacity in series, of an evacuated vessel containing a hot and a plurality of cold electrodes, a conductive connection between said hot electrode and one side of said capacity, a conductive connection between one cold electrode and the'other side of said capacity, and a circuit between another cold electrode and said hot electrode, and containing a high artificial resistance therein, said circuit be ing inductively associatedwith said inductance of said antenna-earth system.
3. The combination with an antenna-earth system including an inductance and a capacity in series, of an evacuated vessel con-'" taining filament electrode, plate and gridelectrodes, a conductive connection between said filament electrode and one side of said capacity, a conductive connection be tween said plate electrode and the other side of said capacity and a circuit between said grid electrode and said filament electrode and inductively associated with the said inductance of said antenna earth circuit.
4. The combination withan antenna-earth system including an inductance and a capacity in series, of an evacuated vessel contaning filament electrode, plate and grid electrodes, a conductive connection between said filament electrode and one side. of said capacity, a conductive connection between said plate electrode and the other side of said capacity and a circuit between said grid nection betweeneone cold electrode and the other side of said capacity, and acirouit between another cold electrode and said hot electrode, inductively associated with said inductance of said antenna-earth circuit.'
6. The combination with'an antenna-earth circuit including an inductance and acapacity in series, of a system for producing continuous undamped oscillations comprising an evacuated vessel containing a hotand a plurality of cold electrodes, a conductive connection between said hot electrode and one side of said capacity, a conductive connection between one cold'electrode and the other side of said capacity, and a circuit becontinuous undamped oscillations cam us ing an evacuated pvessel containing filament,
grid and plate electrodes, a conductive conductively associated with said inductance of said antenna-earth circuit. 7
' 8. The combination with an antenna-earth circuit including an inductance and a capacity in series, of a system for producing continuous undamped oscillations comprising an evacuated vessel containing filament, grid and plate electrodes, a conductive connection between said filament electrode and one side of said capacity, a conductive connection between said plate electrode and the other side of said capacity, and a circuit between said grid and filament electrodes, including a high artificial resistance therein, said circuit being inductively associated with the said inductance of said antenna-earth circuit,
In testimony whereof I have hereunto set my hand on this 7th day of June A. D. 1917.
