TELEPHONIC TRANSMISSION.

SPECIFICATION forming part of Letters Patent No. 766,503, dated August 2, 1904,

Application filed August 2,1902.

To (Ll/Z whom it nuty concern:

Be it known that I, IsrDoE KITsEE, of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements inTelephonic Transmission, of which the following is a specification.

My invention relates to telephony, and has more special reference to long-distance or cable telephony. Its object is to increase the efficiency of the line-wire.

The underlying principle of my invention consists in dividing the line into different sections of such length as in themselves do not offer too great a retarding influence to the passage of the telephonic impulses, in closing these sections through the intervention of inductive devices, and in electrically connecting these closed sections through capacity devices.

Referring now to the drawing, which illustrates in diagrammatic View my invention, A is the transmitter; B, the source of current.

C is the primary of the converter, of which I) is the secondary.

L is the line-wire.

The first section of the line-wire contains the receiver E and the inductive device, such as an electromagnetic coil G. The first section is connected electrically with the second section through the condensers F. The intervening sections consist of the line-wire L and the inductive device G, of which there is preferably one for each terminal of the line-wire. Each of these sections is also connected with the next section through the condenser F.

In the drawing I have illustrated the transmitting-section as to consist of the primary and the first line-section as to contain the secondary; but in some cases it is necessary to omit the battery, and therefore the converter as, for instance, where the line is a part of a whole system centering in one exchange with one'cornmon battery.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A telephonic line divided into two or more sections, each section comprising an electrically-closed circuit containing two inductive devices, and connected with the next Serial No. [18,162. (No modelfl adjoining section with the interposition of a capacity device.

2. A line of electric transmission consisting of a series of sections, each section representing an electrically-closed circuit, each section containing two inductive devices, one of said inductive devices being connected, with the interposition of condensers, to an inductive device of the section following, and the other of said inductive devices being connected, with the interposition of condensers, to an inductive device of the section preceding.

3. In telephonic transmission, a line-wire, said line-wire divided into two or more sections, electromagnetic coils closing electrically each section, and condensers connecting the coils of one section with the coils of the adjoining section.

4. In a system oftelephonic transmission, a conductor divided into two or more sections, each section containing inductive devices and being connected with the adjoining section through condensers.

5. A telephonic line provided with a receiving and sending station, said line consisting of a series of independently-closed electric circuits, each of said circuits containing two inductive devices, the inductive devices of one circuit connected, with the interposition of condensers, to the inductive devices of other circuits.

6. In the transmission of energy, a line of transmission adapted to connect one station with a second station, said line of transmission consisting of a series of independent closed circuits, each of said closed circuits containing two inductive devices, the inductive device of one circuit connected with the interposition of a condenser or condensers to the inductive device of a second circuit.

7. In telephony, a transmitting-station and a receiving-station connected electrically together through a series of closed circuits each containing electromagnetic devices,said closed circuits being in electrical connection with each other through condensers.

8. In the transmission of energy, a line of transmission, said line of transmission consisting of a series of individual independent closed circuits, each of said circuits containing two electromagnetic devices,'the separatelyclosed circuits joined together with the interposition of condensers.

9. In telephony, a transmitting-station and a sending-station, a conducting-line connecting said stations electrically with each other, said conducting-line consisting of.a series of independently-closed circuits, the terminals of each of said closed circuits connected to the terminals of electromagnetic devices, and condensers joining the electromagnetic device of one circuit with the electromagnetic device of the circuit following.

10. Aline of transmission connecting together two telephonic stations, said line of transmission consisting of a number of closed metallic circuits, two electromagnets, one for each end of each of said circuits, and a condenser for each leg of said circuit, said condenser connecting one leg of one of said closed circuits to one leg of the second of said circuits.

phonic station, said line of transmission consisting of a series of independently-closed circuits, connected together through capacity devices, each closed circuit containing two inductive devices, one for each end.

In testimony whereof I hereby sign my name, in the presence of two subscribing Witnesses, this 29th day of November, A. D. 1901.

ISIDOR KITSEE.
