Specification of Letters Patent.
Patented Jan. 4:, 12 15.
hrigi'na'l application filed March 22, 1305, Serial No. 251,538. Divided. and this application filed october 11, 1909. Serial No. 522,083.
To all whom it may concern Be it known that-I, REG'IJALD Fnssnncan, residing at Brant ltock. Flymouth county, in the State of Massachusetts, a
citizen of the United States, have invented.
In the accompanying drawing forming a part of this specification the. figure illustrates diagrammatically the method of producing the oscillations.
The invention herein disclosed has for its object the method of producing high frequency oscillations inan eliicient manner and more particularly themethod of producmg high frequency oscillatlons of a con- .tinuousor practically continuous character and still more'particularly to a method of operating a term of discharge gap foruse in this connection.
In the figure is shown a form of discharge gap adapted for thispurpose and a suitable arrangement of circuits.
The arrangement of circuits is broadly similar to that shown in applicants U. S. Patent 706,742 Figure 10. i
In the figure one of the terminals of the spark gap 128 is formed of a disk 129 which revolves at a speed which may be as high 130 is the anas twelve miles per minute. tenna grounded at 131, 132 is a source of voltage, preferably a continuous current dynamo, 133 is a means of regulating the current adjustable by means of the movable contact 13%, 135 is'a capacity antenna and ground being connected across only a portion of the capacity, e. the plates 136, 137. By this means a high voltage current of small intensity canbe altered into a low voltage current of larger intensity. The inductances formed of the Wires 138, 139 are preferably small and arranged so that together with the capacity 135 they arein tune with the sending conductor.
In operation the rapid relative motion l' tween the two terminals due tothe rapui revolution of the terminal formed ofthe disk 129 produces a rapid and equitable succession of discharges and a high efficiency.
Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the following:
1. In wireless telegraphy, the method of generating oscillating currents for producing radiated waves, which comprises rapidly i'arying conditions of a gap in a closed oscillating circuit by rapidly moving a continuous surface and thereby continuously presenting a new surface of one of the elec trodes in the gap with respect to the other.
2. In wireless telegraphy, the method of generating oscillating currents for producing radiation, which comprises varying the conductive condition of the gap in an oscil latory circuit by rapidly moving acontinuone surface and thereby continuously presenting a new surface of one of the electrodes with respect to the other. whereby the discharge may take place on a. contin- .ually cooled surface With every alternation of current.
In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
REGINALD A. FESSENDEN.
