To all whom it may concern:
Be it known that I, GUGLIELMO MARCONI; a s ubject'of the King of Italy, residing at Marconi House, Strand, "London, England,
have invented new and useful Improvements in Transmitting Apparatus for Use in Wireless Telegraphy and Telephony, of which the following is a specification.
This invention relates 'to"impr'oyements in transmitting apparatus for use in wireless telegraphy and telephony whereby continuous Oscillations or groups of continuous oscillations may be" generated.
The drawing is a' diagram illustrating the nvention. or, '0 c are condensers. c 1s connected 1n series with a source of current a. prfeferably continuous, a'key Z; and
andnductii e resistance 11. The condenser c is also connected in series with the 'conidenser-c and with an inductive. resistance "if d is a toothed disk discharger mounted "on ashaft e which can be rap1dly' rotated so as to cause the'teeth onthe disk almost 7 to bridge a gap in the circuit containing a? is. similarly connected in series iv'ith a third "condenser 0 an induc':
tive resistance? and a discharger d also fast on theshaft e and the condenser 0 is connected in Series with an inductive resistance and a dischar'ger (1 also test on the shaft "e. The dischargers are insulated from one another and are so'adjusted that the circuits 0' 'i'Ic-'*,- c? i 0 are completed and'broken in the above order and at equal intervals. The inductive resistances i' i= i act as primaries to the common secondary s which forms part of an intermediate oscillating circuit f which is coupled to the aerial '9. All the circuits should be in resonance with the aerial;
It will be "seen that condenser 0' discharges into condenser which. discharges int'ocondenserc? which is finally discharged through discharger (Z and inductive resistance i The-spacing of the teeth and the speed of" rotation of the disks'should be such that the aerial is impulscd: at each complete period or otherwise in synchro-d nism with it's-natural period of oscillation. I may use a -larger number of hClICllltS than the three shown.
Suitable means such as an air blast it may be provided in each circuit forquenching thedischarge and for preventing the Specification of Letters Patent.
