effected to a certain extent, such extent, however, not being enough to record the characters. The apparatus in the transmitter for furnishing the varying potential should have 100the same period as the strip 9. The battery of the receiver is of a very high potential, being about one thousand volts. The reason for this high voltage is to keep the diaphragm 6 under a static field, thus making the same 105more sensitive in the same manner as the common magnetic field in magneto-telephones makes them more sensitive.
This application is a divisional application which was originally covered and set forth in the 110application for wireless telegraphy, filed October 25, 1901, Serial No. 79,959.
I have found by experimenting that the grounds of the transmitter and receiver should be substantially the same distance 115apart—say from twenty to thirty feet—and that the distance between the diaphragm 6 and the disk 11 should not be over one-eighth to one fourth of an inch.
What I claim as new, and desire to secure 120by Letters Patent, is—
1. A receiver, which comprises a plurality of plates in inductive relation, means for permanently charging the plates and a local circuit controlled by said plates.
1252. A receiver, which comprises a plurality of plates in inductive relation, a source of high potential energy in connection with opposing plates through an earth-circuit.
3. A receiver, which comprises opposing 130plates, a high-potential source of energy connected to said plates through an earth-circuit to permanently charge the same, and a circuit-controlling means operated by the reaction between said plates upon the reception 135of a signal.
4. A receiver, which comprises plates in inductive relation to each other, means for normally charging said plates to a high potential, means controlling a local signal-circuit 140operated upon fluctuations of charge on said plates due to received signal energy.
5. A receiver, which comprises a plurality of plates in inductive relation, batteries of high potential permanently charging the 145plates, and a local circuit controlled by said plates.
6. A receiver, which comprises a plurality of plates in inductive relation, a battery of high-potential energy in connection with 150opposing plates of an earth-circuit.
7. A receiver, which comprises opposing plates, a battery of high potential connected to said plates through an earth-circuit to permanently charge the plates, and a circuit-controlling means operated by the reaction155 between said plates upon the reception of a signal.
8. A receiver, which comprises a plurality of plates in inductive relation to each other, a battery for normally charging said plates165 to a high potential, means controlling a local signal-circuit operated upon fluctuations and charged on said plates due to received signal energy.
9. A receiver, which comprises a plurality170 of plates in inductive relation, batteries of high potential permanently charging the plates, means kept under an electrostatic field interposed between said batteries and one of the plates, and a local circuit controlled by175 said plates.
10. A receiver, which comprises a plurality of plates, a high-potential source of energy connected to said plates and an electrostatic means interposed between one of the plates180 and the high-potential source of energy.
11. A receiver, which comprises a plurality of plates, a high potential source of energy connected to said plates, an electrostatic means interposed between on of the plates and the source of energy, and a recorder instrument controlled by said means.
12. A receiver, which comprises a plurality of plates, a source of high-potential energy connected to said plates and an electrostatic185 means interposed between one of the plates and the source of energy, a relay-circuit controlled by said means and a recorder-circuit controlled by said relay-circuit.
13. A receiver, which comprises a plurality190 of plates, a diaphragm surround by insulation connected to one of the plates, a battery of high potential interposed between the plate and diaphragm, a disk adjacent to the diaphragm and connected to the other plate so195 as to be kept under an electrostatic field, and a recorder controlled by said disk.
14. A receiver, comprising a plurality of ground-plates, a high-potential source of energy interposed therebetween, a diaphragm200 connected directly with the source of energy, a disk mounted so as to be free to vibrate adjacent to said diaphragm and kept under an electrostatic influence by said source of energy, said plate of disk being directly 205connected to the other of the ground-plates and a recorder-circuit controlled by the disk.
In testimony whereof I affix my signature in the presence of two witnesses.
