11, wire 34, contact the return sitlc of the battery; i The current flowing through this eircuit is su'fiicient to cause a greater energization of relay B and the con'iplete 'aetuatiou of its contacts, causing contact 8 to disengage contact 9 and to engage contact 10. The disengagementof contact 9 interrupts the'circuit of the regiser and relay 1. and the engagement with contact it) closes a locking circuit for relay B which may he racerl as follows: from the active terminal of battery 53, through Wire 35, winding 6, lamp 313, contacts 13,8 and 7, key .18, 21ml wire 32 to the return side of the battery. This went serves to maintain the COil'lplCLt: a -LoiOl1 of the arniatures of relay B and to cause the illumination of the lamp l3, and the registerlt and relay 19 have assumed their normal positions in readiness for a subsequentcggeration. The illumination of lamp 13 indicates to the attendant that the line associated with that lamp is in trouble who, when the trouble has been remedied, interupts the locking circuit just traced. by depressing the key 18, thus allowing the relay contacts to assume their normal positions. it) will be obvious, therefore, that if line A be in trouble signals may be traced. through regis-' received from line A or A or vice vcrsu Witl'iout interference from such trouble.

Fig. 2 illustrates diagrammatically a modification of the structure of l ig. l, in that the register ll in a normally closed circuit, which may be traced from the upper terminal of battery (7, through the magnet Winding of register R, the winding of magnet 19, and thence through wire 36, contact 28 am} or aturc 27 ot' relay li,' :o11t:ict 528 mu! armature P2? of relay ii, and contact 28 and armature 2'? ol' rclay ii. to the return siile oi" the battery through wire 3. 'lhe current, which flows through this circuit normally, holds the miniature ot' the register out of engagement with the tapwwlu-el and the armature of relay ll) out of engagement with its contact 31. ll, :1 signal be sent over line .L, the consequcut cnci'giz-ation of relay l: causes armaiun- 27 to engage contact 2h anti :u'n'iaturc 23 to cngago contact 5, but is insufficient to rzulyrc a further actuation oi the armature. 'lhc :ua'uutiou of armz-iture 27 at this time iut-tes'rupts the circuit of the register anti rc lay ii) in the predetermined manner, thus causing proper signals to be miltlih The intori-notions, however, are of such short duamt magnet 19 are included ration that. arnuuure 21 does not engage tact 31, and consequently no current results from the eiwagement of arina-tur with contact :25. ff, however, through the accidental grounding of limb 1 of line A, the relay li be energized for more than the normal duration, armature "2'1 of relay 19 "will engage its contact Eli during the time that armature 523 of relay B engages its con tact 2-3, and current will flow over the circuit which may be traced from the upper terminal of battery through wire l0, key 18, lamp 13, winding t) of relay B. armature 23, con-tact contact 24, wire 88, contact 3], and armati-u'e 2t to the return side of the battery. This current causes an increased mergiaation of the magnet of relay it and a comp-h te attraction of its ari'natures. The cm'nplete actuation of armature 27 again closes the circuit of register R and relay 19 at contacts 30, 29 and 27', thus placing them in readiness for operation by currents on line .X or 4V. The complete actuation of armature causes contact to engage contact it) 556 and subsequently break contact 2i, and this operation completes a kicking circuit inc-hiding the signal lamp 13, which may be traced from the upper terminal of battery C, through" wire it), key 18, lamp 123, wind mg (i, armature 23, contact 25. contact 26, and wire 39 to the opposite side of the battery, thus maintaining the attraction of the relay arinatures and the display of the signal until the circuitis interrupted by the a tendant as in Fig. i.

\Vhile l have illustrated my invention as embodied in a combined telephone and alarm signaling systcn'i, do not wish to be limited to this particular embodiment, as it is o vious that it ina y be used in connection with many other signaling structures. While the relays B, l3, B are diagrammatically illustrated as having two arniatures, it is evident that any so-called double-acting relay ma be used, in which the contacts controlled by the relay magnet have two operative positions other than the normal one. Llitewise lamp 13 or the register B maybe replaced by any preferred signaling mechanisms, and also that various other ways of supplying current to the various circuits may be used, other than that of having one common source. I therefore do not Wish to be limited to the structure illustrated and de scribed, but aim to cover an" variations or modifications of the invention by the following claims:
