S erial N0. Q76, 192.
To all whom it may concern:
Be it known that I, Ennmnno 'Lorroonra, a citizen of the Republic o Mexico, and a resident of Montercy, in the State of Nuevo Leon and Republic 01 Mexico, have invented certain no and useful Improvements in To]egrapli llcpcaters, of which the following is a specification.
My invention is an inrirovement in telegraph repeaters, and consists in certain novel cons motions and combinations of parts hereinafter described and claimed.
The object of the invention is to provide an automatic repeater without the use of com ensating rheostats, or the necessity of employing dill'crential relays, and. to provide an apparatus by which any ollice may be converted into a rc ieating ollice, by utilizing the existing apparatus, it only being necessaryto substitute the repeating sounder for the ordinary local.
Referring to the drawings forming a part hereof Figure 1 is a side view of the repeatm'. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a diagrammatic view of the connections of one repeater, and Fig. 4 is simila View of both transmitters and both repeaters.
In the present embodiment of the invention, the repeater comprises a pair of magnets 1, and a transmitting arm or lever 2 pivoted as at 3, the one end being movable between the face 1, and the overhanging arm 5 of a bracket 6, and limited in its movement by set screws 7 and S, threaded through the face and through the overhanging arm respectively.
The arm is normally moved away from the magnet by a spring 9, having one end connected to depending arm 10 on the transmitting arm, and having the other arm ongaged by a set screw 11 traversing the bracket. The other end of the arm is eX- tended as at 12, and provided with a cross head 13.
Pivoted ] evers 18, 19 are arranged above and below the transmitting arm, the said levers being provided with contact points 20 2O normally engaging other contact points 21, 21 secured to and insulated from a plate 22 arranged alongside the transmitting arm. The lovers are normally retained with the contact points in contact by springs 23.
The tongues are pivoted on a set screw 21, which traverses the plate, an insulating l collar 25 encircling the set screw, within the opening through the plate, and washers 2c of insulating material are arranged between the levers and the nut 27 as clearly shown in Fig. 2, to properly insulate the set screw from the plate.
It will be observed that the contact points 20, 2O ol' the tongues 18, 19 are normally in contact with the contact points 21, 21, so that the circuits connected with the respective sets of points are i'iormally closed, when. not engaged by the ends 01 the cross head. lVhen hmvevcr, the transmitting arm is operated the ends of the cross head will alternately engage the lovers 18, 19 to open the said circuits, the circuits connected with the contact points 20, 21 being opened by the downward movement of the transmitter arm, and the circuit connected with the contact points 20, 21 being opened on the upward movement of the transmitter arm.
The improved. repeater is used in connection with the ordinary transmitter, two 01 which are shown in Fig. 4, one 28 being connectcd with what may be distinguished as the main line, and the other 2S with the branch line. A repeater (lesignatcd in its entirety as 29, 29 is used in connection with each transmitter, and keys 3O 30 are inter.- posed in the circuit for operating each transmitter. The circuit of the main line A, passes through the key 30, and the wimlings of the relay 28, to a binding post a, on the repeater 29, and passes from the binding post to the contact point 2] below the transmitter arm, the circuit having a branch (1. leading to a button a on a switch 31 connected with the repeater.
From the contact point 21 the current of the main line circuit passes to the tongue 19, and from thence to a binding post a on the repeater 29 and out over the line, a branch a leading to a button a" on the switch.
The branch circuit B passes through the key 30, and the coils ol the transmitter 2S" to a binding post I), on the repeater 29, and from the binding post to the contact point 21, through the tongue 19 to a binding post I)" on the re mater, and out on the branch line, a brandh b leading to a button 6" on the switch 31 01' the repeater 29.
Each oi" the transmitting lovers of the transmitters 28, and 2S is utilized to open peatcr 29, and if", Z) for the repeater 29", each local circult containin a batter a and close a local circuit a a." for the re- 5 and passing through the coils of the magnets of the repeaters 29 and 29 respectively. A circuit 07, a b, b is branched onto each of the local circuits, and has its terminals in the contact point and tongue of the opposite repeater, the circuits being connected with binding posts a a, b 1) on the repeaters.
When the key 30 of the main line circuit is opened, a signal is transmitted over the main line circuit through the contact point 21 a and the tongue 19, and a signal is also transmitted by means of the local circuit a a through the repeater 29.
The movement of the transmitting lever of the repeater 29 when opening, opens the branch line circuit through the engagement of the transmitting arm with the spring tongue 19. Through the movement or the transmitting lever of the branch line transmitters, the local circuit of the repeater 29" would be also opened, but by the opening movement of the transmitting lever of the repeater 29, which permits the spring tongue 18 to connect it with the point 21 this is prevented.
The repeaters may be prevented from interfering with the opposite line circuits by moving the switch arm 31 and 31 as the case may be to connect the buttons a a 1)", b of the respective switches.
I claim 2- 1. The combination with the main line and the branch line circuits, of a transmitter and a repeater in connection with each circuit, the repeater having a transmitting lever ex tended rearwardly and provided with a cross head, each of said line circuits having terminals below the extension of the opposite repeater, one of said terminals consisting of a spring tongue normally in engagement with the other terminal and in position for engagement by the cross head whereby to disengage it therefrom, a local circuit for operating each repeater and opened and closed by the transmitting lever of the transmitter, a circuit branched on the local circuit and having terminals above the extension, and normally in contact, one of said terminals consisting of a lever which is separated from the other by the crosshead when the repeater is closed.
2. The combination with the main line and the branch line circuits, of a transmitter and a re eater in connection with each circuit, a loccl circuit for each repeater operated by the transmitting lever of the corresponding relay, a circuit breaker in parallel with each repeater, and between the repeater and the transmitter, and means whereby the transmitting lever of the one repeater will operate the circuit breaker of the other repeater to close the local circuit thereof, when the local circuit connected with the first repeater is open.
3. In a device of the class described, the combination with the main line and the branch line circuits, of a relay and a repeater, in connection with each circuit, a local circuit for operating each repeater passing through the transmitting lever of the corresponding relay, and a normally open circuit branched thereon and closed by the opening of the opposite repeater.
4. In a device of the class described, a plurality of transmitters, and a repeater for each transmitter, a local circuit for each repeater opened and closed by the corresponding transmitter, and means operated by the one repeater for retaining the circuit of the other repeater closed during the operation of the first repeater.
