To; all wh m i my camera:
Be it known that I, HARRY O. RUGH, citizen oil the United States, residing at Sandwich, in the county of Dekalb and State of, Illinois, have invented a certain new and useful, Improvement in Selective Signaling Systems, 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 signaling systems, and more particularly to signaling systems as applied for use along a railway right-ofwary,,and has tor its object the provision of an improved device for selectively calling the various stations from a central office.
I will describe my invention more in do taiLby reference to the accompanying drawing illustrating the preferred embodiment thereof. I have there shown a line circuit consisting of the line wires 1 and 2, which unites the central station A with the various substations B, C and I). The line wires 1 and 2 are joined, at both extremities through v impedance coils 3 and i, which impedance over the line, contact 18 is included in the coils are esigned to prevnt the passage circuit to actuate relay 28, which thereby therethrough of telephoniccurrents in su releases the step-up mechanism 23,- and alcient quantity to disturb proper intercomlows it to come tonormal through the munication between the various telephone agency of the spring 29. Nhen the step-up sets at the various stations, which telephone mechanism sets consist of the transmitter 5, battery 6,
comes to normal, it opens contact through the spring 30, thus preventing induction coil 7, condenser '8, the switch- These telephone the further actuation by negative impulses of the relay 28. It will be seen from this that sets are bridged across the line circuitof the various stations. At the centralstation the polarized relay 15 has two coils, one COll telephone, in addition to the telephone set having a terminal connected to the line conductorl, and the other coil having a ter- A, shown, there are also provided two generaters 11 and 12 having one terminal con- ;points 1.7 and 18, leading directly to wires 19 and, 20, respectively, with. an additional third wire 21 connected to the armature 16, itself. Thus, when positive currents are transmitted over. the line conductors,,contactpoint 17 is included in circuit to actuate the relay 22, thereby to step upthe stepup mechanism 23, which. stcpmp mechanism is provided with a contact lever 24, adapted to engage contact spring 25, when it is inthe proper position, thus to operate a local signal 26. The arms 24: are, of in different positions angnlarly, so that the desired station can upon the number of impulses transm t over the line to actuate the relay 22. Alocal relay 27 serves to close the circuit through the signal 26. It will be apparent that the impulses to relays 22 must be short in duration, so that when station I), for instance, is wanted, the contact arms 24, in passing :their springs 25, at other stations, will not make contact long enough to permit the slow-acting relays 27 to close \iVhen negative impulses are transmitted.
minal connected to the line conductor While I have herein shown and described nected to the ground, and having keys 13 the preferred embodiment of my invention, and 14, which are adapted, respectively, to I do not limit myself to the particular conconnect either one generator or the other struction I have shown, but having set forth what I claim as Letters Patits most salient generator to the line conductors 1 and 2, I
