To all whomc't may concern Be it known that I, HARRY C. CAHILL, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Im provements in Repeaters for Telegraph- Lines, of which the following 1s a specification. I
This inventionrelates to telegraph repeaters and the object of theinvention is to provide a device whereby messagesv or electrical impulses in one circuit orloop may be transmitted to and reproduced in a second loop or circuit without contact between the two, both circuits being providedwith batteries independent of the battery for the trans-v mitting instrumentalities. I
With the foregoing and other objects 1n view, the invention consists in the novel construction, combination and arrangement of parts constituting the invention to be hereinafter specifically described and illustrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the inventioinbut it is to be understood that, changes, variations and modifications can be resorted to whichcome within the scope of the matter hereinafter claimed.
The drawing presented is a diagrammatic view of a preferred form of a device embodying my invention.
One loop or circuit is denominated by the reference numeral 1 and the other by the reference numeral 2, and the invention makes it possible by the mechanism hereinafter described to transmit a message from the loop 1 to theloop 2 and vice versa without directly connecting the two together. In the loops 1 and 2 are relays 3 and 4 respectively supplied with batteries 5 and 6 respectively. The battery 5, is connected with a contact member 7 by means of a wire 8. I
Adapted to contact with the member 7 is an armature 9. The battery 6 is connected with a contact member 10 by means of a wire 11 and engaging the contact member 10 is an armature 12. The armature 12 is connected with a ground by a wire 13 and the wire 13 is connected to the armature 9 by a wire 14:. The armature 12 is oscillated by means of a relay 15 connected by wire 16 with the ground wire 13 and by a wire 17 with a battery 18 from which extends a wire 19 to an armature 20 adapted to contact with an insulating post 21, but when oscillated adaptedto contact with a member 22 connected by a wire 23 with the wire 8. The armature 9 is oscillated by a relay 24 connected by wire 25 with the wire 14: and
also by wire 26 with a local battery 27 a which in turn is connectedby a wire 28 with.
an armature 29 normally in contact with an insulated post 30 but when oscillated is adapted to form an electrical contact with the member 31 connected with the member 32by the wire 11'. All of the armatures constitute circuit breakers for apurpose to be later described;
In practice, assuming that a message or an impulse is to be transmitted from the circuit 1 to the circuit 2, the following operation takes place: The circuit 1 being normally closed relay 3, is constantly energized and the armature 20, is thereby held against the post 21, so that the current in the circuit 1 will pass through the relay 3, battery 5, wire 8, contact 7, armature 9, wires 14 and 13, to the ground, and from thence to the sending station. The, opening of the circuit 1 deenergizes the relay 3, permitting a spring 33 to draw the armature 20 against the contact member 22 closing the circuit made up of the armature 20, wire 19, battery 18, wire '17 relay 15, which is thereby energized, wire 16, wires 13 and 14, armature 9, contact 7 wires 8 and 23., to the contact member 22. The energizing of the relay 15 oscillates the armature 12 overcoming the resistance of the spring 34, thereby opening the main circuit 2, and of course, as soon as the relay 3 is reenergized the armature 20 will be oscillated into engagement with the insulating post 21 thereby opening the local circuit through the relay 15, permitting the springldd to draw the armature or circuit breaker 12 into contact with the member 10 thereby closing main circuit 2. The same operation takes place if a message is to be transmitted from the main circuit 2 to the circuit 1. In this case, however, the deenergizing of the relay 4 permits the spring 35 to close the local circuit through the relay 24: which overcomes the resistance of the spring 36, opening the circuit 1 through the relay 3, and of course transmits or repeats the various makes and breaks of the first circuit.
I claim In a device for repeating electrical imthereto, a battery connected to said relay magnet, a contact connected to saidbattery, a switch arm normally 1n engagement wlth said contact, a ground wire leading from 7 said switch arm to a ground, a second 11116- wire, a second magnet connectedto the sec-1 magnet arranged to attract the first switch arm, a fourth magnet arranged to attract the second'switch arm, a ground wire leading from the third magnet to the first ground wire, a ground wire leading from the fourth 'magnet to the first ground wire, a third switch arm normally attracted'by the first magnet, a connection between the third switch arm'and the fourth magnet including a battery, a fourth switch arm normally attracted by the second magnet, a connection between the fourth switch arm and the third magnet including a battery, a contact with which said third switch arm is adapted to engage when the first magnet In testimony whereof I have hereunto. set it my hand in presence of two subscribing witnesses.
