Specification of Letters Patent.
OF SAID FRANCIS J. MoCARTY, DECEASED, ASSIGN OR FRANCISCO, CALIEOR 00., or SAN Batented Tune 18, 1907.
,Application filed February 12, 1906. Serial No. 300,639-
.Z'o alt whom, it may concern: I
Be it known that I, FRANCIS J. MoCARTY,
a citizen of the United States, residing at the city and countyof San Francisco and State 5 of California, have invented new and useful Improvements in 1 Wireless Telephones, of
which the followin 'is a specification.
My invention rel ates to a device by which telephonic messages may be transmitted 10 without the aid of wires or other mechanical intermediate connections between the stations..
It consists in a combination of devices whereby vibrations produced by vocal [5 sounds in the apparatus are capable of transmission throug the medium surrounding the earth Without the aid of Wires or'similar conncctions; and in the-construction of mechanism at the receiving end whereby such vibrao tions are made capable of actuating a receiving diaphragm.
Referring to the accompanying drawings,- Figure .1 is a diagrammatic view of the transmitting apparatus. Fig. 2 is a similar view of 5 thereceiving apparatus. 7
.A is a mouth-piece.
' 2 is a tube into the side of which the mouthpiece ens At one end of this tube is the microp one transmitter, as at 3, and at the o opposite end of the tube is the'transmitter diaphragm 4.
represents an induction or Ruhmkorff coil having two primary windings of wires 6 and 7, and in conjunction with these a secondary 5 insulated-winding as at 8. The first primary wire 6 is connected through a wire 6 and a binding post 9, point 10, which is adjustable in the non-conducting case within which the diaphragm 4 is y fixed, and this diaphragm-has"the' contact 11 corresponding with the contact 10. The contacts may be of platinum, Upon the opposite side of the diaphragm 4 is another contact20, and 21 is position to the contact 20.
6 is a wire or metallic connection between contact 21 and contact 10.
The points 20 and 21 are normally in contact and through the connections with the battery form a closed circuit, while the circuit'through thev contacts 10 and 11 is normally open. When a vibration of the diaspark to be with the contact screw or a contact supported in opshown by the arrow 19-, and thence to any phragm 4. takes place the circuit through contacts 21 and is broken by the outward movement of the diaphragrmand a circuit is established through the contacts 10 and 11.
In the operation of the device, words spoken into the mouth-piece will cause the vibration of both the diaphragmsS and 4.
The effect of these sonorousi vibrations on the diaphragm 4 is to cause it to make and break the. circuit in unison with the vocal sounds first between contacts 10 and 11, and then between 20 and 21. The effect of the sonorous vibrations on the microphone 3 is to vary the current in the second unison with the sonorous vibrations. The resultant eflect on the secondarycauses a The spark produced bears all the characteristics of the vocal or other sounds,'. thereby medium imparting wavesto the etherial which will be recorded'on a receiver tance.
- From the bindin post 9, the wire 6 connects with wire 6 or the coil, thence the wire 6 connects with the battery as at 12, thence to the binding post 13 of the transmitter 4.
14 is a condenser having wires connecting the binding-posts 93 and 13 with the priat a dis- -mary wire 6, and this serves to prevent sparking at the contacts of the transmitter.
The microphone transmitter 3 has the binding-posts 15 and 16 with which the ends of the second primary wire 7 are connected, with a battery interposed as at 17. I
In the operation of the device, words spoken into the mouth-pieceA will cause a v1bration of both the diaphra m 4 and that within the transmitter 3, and t e vibration of the microphone transmitter being synchronous with the vibrations of the diaphragm 4, the effect produced by the double primary winding of the coil 5 is transmitted through the secondary windin 8, and the discharge points 18, to the aeria conductor in the line suitable receiver.
I have found that any primary of a Ruhmkorfl' coil which has a second layer of wire wound over it serves to choke ofi theefiect of current inthe first primary on the secondary, if it-be suddenly short-circuited, and that by connecting an ordinary microphone transprimary in generated at the spark gap 18.-
