RAPHONE COMPANY, SOUTH DAKOTA.
OF CHICAGO, ILLINOIS, A CORPORATION OF TELEGRAPHY.
SPECIFICATION forming part of Letters Patent No. 757,505, dated A ril 19, 1904.
Application filed August 31,1903. Serial No. 171,400. (No model.)
To all whown it may concern.-
Be itknown that I, HARRY O. RUGH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Telegraphy, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to telegraphy, and has for its object the provision of an improved system and apparatus whereby wave-form current as alternating current of suitably high frequency may be employed in effecting telegraphic signals. By means of my invention the same telegraphic circuit may be simultaneously employed for both wave-form anddirect telegraphic currents. To this end I have devised apparatus at the stations employing the instruments to be operated by wave-form current that will effectively respond to the wave-form current at the receiving-stations and which will also be operated at the sending-station without unduly weakening the current, the system enabling the substantially uniform operation of the sounder at the receiving and sending stations.
My invention will be fully pointed out in the following specification and claims and illustrated in the accompanying drawings, in which Figure 1 illustrates the preferred embodiment of the invention. Fig. 2 is a view in elevation of the sounder.
Like parts are indicated by similar characters of reference in both views.
I have indicated a transmission-line 1, common to a plurality of telegraphic stations 2, 3, 4, 5, and 6. It is understood that the num ber of each kind of stations may be varied.
dance 11 may be included in the line if said linerelays do not ofler enough to prevent undue leakage of wave-form current.
I have indicated the apparatus at stations 3, 4, and 5 in grounded conductors 12, each containing a condenser 13. At each of these stations there is a line-relay 14:, each preferrent caused by the battery 8 that may find path through the'condensers 12 to the relays 14 will fail to cause effective operation of said relays, because the contact 20 is maintained in engagement with the diaphragm not only by reason of the weighted arm, but also by the adjusting-spring 20, that serves to regulate the degree of pressure of the contact against the diaphragm. W ave-form current of sufficiently high frequency, however, will cause separation between thevibratory and traveling contact elements.
At each station there is a sounder 21 contained in a local circuit including the contacts 16 and 17 and a battery 22. Whenever waveform telegraphic current is impressed upon the line relays at receiving-stations, the contacts 16 and 17 are separated. The preferred source of wave-form current is an alternatingcurrent generator 22, one generator being in dicated at each of the stations 3, 4, and 5. It is of course only necessary to have wires carrying the wave-form current present at'each station to act as a supply irrespective of the location of the generator supplying said wires.
A sending-key or switching mechanism 23 I is located at each of the stations 3, 4, and 5,
whose normal contact normally completes the relay-circuit to ground, the ground connection being by way of said key, which is preferably constantly grounded. The alternate contact of said key constitutes a terminal vof the supply of wave-form current. when said key is depressed, the magnet of the relay 14 is cut out of circuit. In order that the wave-form current impressed upon the line at a sendingstation may operate the sounder to the satisfaction of the sender, I have herein provided an electromagnet 24: at each station that is ineluded in circuit with the source of wave-form current at a sending-station. This electromagnet when energized by outgoing waveform current attracts its armature away from the normal contact 25 to open the soundercircuit that also contains said armature with its contact, whereby the operator gets his own sending. In order that a sound occasioned by the release of the sounder-armature may be totally distinct from that occasioned by its attraction, I provide a sound-'dampener 26, that is engaged by the armature-screw 27 upon the attraction of said armature.
It is obvious that changes may be made in the embodiment of the invention herein shown a without departing from the spirit of the invention.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent, the following:
