Application filed July 0, 1900. Serial No. 441,971.
To all whom 'it muy concern.'
it known that l, Fama E. "i'oon, a citizen of the United States, and a resident of the city. county. and State of New iiork, United States oi' America, have invented certain new and useful improvements 1n Electric Signal Systems, of which thc following is a s cit'ication.
My invention relates to improvements in electric signal systems such as are commonly uscd for tire alarm, telegraph, or police signal service, and its object ifi to improve upon apparatus and circuits used in auch systems ami to procida a simple apparatus und connecting circuits by ineami of which an cicient and reliable service may be attained.
'lo these ends my invention resides in the construction and arrangement. of parts described in the followin specification, the novel features of whici are set forth in claims.
Referring to the drawings, Figure 1 iu n diagrammatic representation of my invention. In this figure the receiving apparatus, such as may bc installed in a central station, is shown electrically connected with n fire alarm box and an auxiliary the station, and with a police call station. Fig. 2 is a diagram of circuits and certain parts of the apparatus with only so much of thc latter shown as is necessary to illustrate the operation of my invention.
Like characters of roferenco designato corrcaponding parte iu both of thc tignrcs.
lt) designata thc cnsin of a tire alarm box within which a nu-Ialllic frainell is located, which, ucar its nppcr portion pivotally supports a spur-gear 12, from the face of which a series of pins 12^ project. The gear l2 is arranged to be driven by u coiled spring lil.
H is u pinion in mcs-Ii with thc gear l2 and carries an urni Il` which in arranged to rotate with thc inion for u purpose which will appear hereinafter. 15, mounted upon the .same arbor with the pinion 1i. iu arranged to tranuinit ntohon to udbthcr pinion not shown which is rigidly mounted `upon an arbor tti. v A gear-wheel 1T, also mounted upon the arbor lt, actnates y an eacapenienti wheel 1S and an escapenient hitch lit. A signal disk is also :wcurcd to the arbor l0.' An insulated contact finger 21, eonctin v with this disk. is arranged to malte and realt an electric circuit.ia the usual manner whenever thc disk is rotated.
.\nothcr spur-gear4 of solenoid 30.
In the drawings, the disk arid finger are arranged for a closed circuit system, und thc signal number for which they are constructed is 43. The parts above dcecribcd arc normally hold from rotation'bv meana of a finger 2i. which is atiixed to tite arbor 16 and which rests upon a pin 28 pro'ecting from the lowercnd of u lever 24 w ich is pivoted at in the frame 11. An arm 26, which is an integral part of lever 25, extends above and to the right of this pivot und terminates in a hook or shoulder 27 which is adjacent. to the path of movement. of the pins 1.!^. The lower end of lever Q4 is malle with a lateral projection 28.
designate's'an unlocking solenoid supported upon the fraaie 11. To the lowei` end of its core 31 is a vhorizontal -arm 82 which normally rests against thc latter projection 28 on the lower end of lever 24 in auch a way as to hold the pin in the path 'of the arm 2:2 and thus maintain the mechanism at rest. The winding of solenoid 30 is included in a normallr open circuit under control of a lswitch which comprises` n movablc contact inaulated from but mounted upon the side of n switch-arm which is piroted at 4| and which is arranged to be moved into Huch u position mi to lnitbe two stationary contacts 2H und 3.1. 'iic pirated switch-arni 40 is also provided with u depending contact finger :iti which is ai'- rangcd to bc moved orcrstationary nntilated contact plates 37, 3H and 3i.
4:.' isa push-rod projcctiu.;r thronc'h the side of tho box l0 and spring-pressoiroutward. liy mcans'loi' this pushdvd thc pirated arm 40 may bc manually shifted to cause the contact plate 33 to bridge contacts 34 and 35 and at the same time more the contact linger .'lt' into such a position that it will Inid rc contacts l and 3H. circuit unplplict by n battery llt) at. the central station will hccloscd thereby through the winding 'lhe encrgizution of this solenoid will canse it to raise its core 31 and to more the arm 32 out of engagement with thc `houlder lci'cr :24 so that :i spring` 2t) which is in on- ;:ngemcnt with the lover will pnsli it over until the piu 23 is removed from thc )ath of movement of the arm 22. The sign lucchuaism aborc described is unlocked thereby and rotated by the spring 18' so that the make and break dcvicesnrill transmit the desired signal to the central ndice over a cir- 28 on the pivoted releasing,
l llt) iid cuit which l will .specifically point out hereinafter. lever will ciiuse its end 2T to be. inovd into the path of rnovement of the pins 1.2^ on the wheel 1Q.
'llie otury signal inecliunisin in no errlngedihnt ufter the signal dish 20 hns conipleted four revolutions, the iirni lt^ will enga with an inclined shoulder tt on switc -iirm 40 and will return this iirin to its normal ioeition, thus breaking the circuit througi solenoid 30 and bringing the contact. finger 36 to its originel `position to bridge libitioniiry contncts 38 un 3 This will at the sinne time euuse the core 31 und its connected parts to drop back into lockition to prevent further rotation of the signal disk.
In connection with theinnnual operation above described, it is often desirable to use in conjunction with such s ignnlbox one or more auxiliary stations such as 50, which may be electrically connected with the inaniter-box or station. The electricnl actuating meehiininm in the box 10 comprises ii nolendd 44 which` when energized, will pull down its cre 45, which is connected at 46 with the pivoted switch-erin 40. in such o manner thiit this downward movement of the core will shift the nwitchmrin t0 into the nme position and will cause it to perform the same functions as would be accomplished b iiiiinuiill pushing it. over by ineens of t e push- 42.
A buttery 51 is provided at the auxiliary station an this is connected by a wire 52 with the master-box. The mechanism in the nuiiliarv tation box comprises n wound-up spring (not shown), which is nrrnnged to rotate a disk 63, which disk is connected with the other terminal of the battery 51 by ii coiituct finger 54. The disk 53 is set in niotion whenever the locking lever 55 is pulled buck by the hook 50 out of engagement with the pin 5T upon the disk. -68 is u emituetfingcr adapted to engage with the periphery of the dink 53 when the latter is rotated, und this is 'eonl'iected through n. buzzer 59 b v u wire 58^ with one ot' the terminals ot the nwitchnrin iictunting .solenoid 44. notch-or depression 53'* in the disk 53. directly `below the contnct fiug'er 5R, leiires this circuit open at thin point.

dil'is ii liniiiiiier connected with the upper p'oitioii of lever til und udn lcd to l-trilie against u bell 64 whenever tie lever til is nulled bark by s ring 6.7.
When the dis 53 rotates, it closes a circuit from battery 5t, dish 53, contiict iiigel' 58, through buzzer 5t), 'conductor 58", j of' ii lnindle 73.
1 eccoci Ioolenoid -t-t, out through conductor il",

which is uninet-ted nt. 44 with the sigiinl circuit 108 which is connected with the finger .l und through the signal disk 20 and tho wire 52 buck to the other'tcrininul of buttery fil. A second circuit in ulno closed in the auxiliary box as follows: From battery i'il, through contiict finger o8, conductor titi, winding of magnet. 60, iiud conductor 6T to the box 10. und through the solenoid 44 und signal disk 20 beck to buttery fit by conductor 52. If the circuiti, ure in proper order the muguet 44 will be energized and the buzzer 5t) will be put into uetion to indiente this fuct. The second circuit which go'cs through the niugnets 60 and 44- will continue "to energize theni until the signiil is sent in from the signal disk 2u in the master-box. If thc other circuits are in such condition iis to lock the signal nicchiinism within box 10 in'it manner which 1 will later describe, the u per end of pivotcd lever 6l engaging with tlie pin 57 will hold disk b3 from further rotation und thus hohl the two circuits of the auxilinry ntiitioii cloned until such time iis the i-iignnl is sent in by the mechanism within the box 10. When the signal circuit is interniitteiitl broken nt the signal disk 20, the signal wi l be repented within the nuxiliury box because thc muguet. 00 will be intermittently denergized und will thus nllow the spring 05 to pull the hummer (33 over s minst the bell 64, und this.
will also stop the uzzer intermittently. As soon as the circuit. through the magnet 60 is first broken, it will allow the disk 53 to complete itii rotation until the pin 5T is nguin engngeil by the locking lever 55. The uetuuting ineehiiiiiiini which I have not shown, im' it is well underiitood und torinii no part of the present invention, should be so uri'unged thut the rotation of the disk 53 should not he completed in less time thiiii it tultes for the dii-ik S20 to send in its siginil, in order thnt the complete Hignnl muy be received within the auxiliary box 50. Should niiotlicr box be sending in its signiil the inechiinisin within the nuxiliury box will be held in cheek, and the buzzer constantly voinf.: until the .box i.-i iillowed to toko lie line. lt is evident thut niiy nuniber of these uiixilinry boxes uniy lie connected with every iuii.-ter-tut ion auch iis tluit represented.

Besides the teeth corroa riding with the signal of thc. lios. thc dit 77 is providcd with teeth l, 2, :t und 4 with which contact fingers 1^, 2^, 3^, nml 4^ coperate, respectivel to elect the sending of certain calla such, or exam le as i'cpoi't call, telephone cell, am iu ance cull," and wagon call. For the purpose of selecting and controlling these several calls a switch-arm 80 is provided. This is pivoted at 8l and carries an insulated contact tingcr 82 which may, he moved onto any one of four stationary contacts 1", 2", 3, and 0 coinected with :lhs contact n rs 1^, 2^, an 4^, res iv y. The contacstetlnger 78, which coperiiet: with the disk 70, and the contact finger .82 are connected with tho line wire 106 of the aignaling circuit. The use of the disk 76 and the eentact linger 78, arranged as above described, is importent for insiirin the tranembion of thc desired signal. I s contact Inlet 89 is normally in contact with stationeentact l' which may be in the report ca l circuit, so that when the box ia operated from the outside, this call will he sent. The switch-arm B0 is preferably inside of the box where it is acceible only to a policemanoreomsother rsonhaving akeythereto.

A hiver titl. pivoted inl the fronte l itt D4, is provided at its lowcr cnil with a liiteriil projection with n lshoulder 95 which normally bears agniimt the arm 91. A pin 96 projects from lever 93 and is normally disposed in the path of a finger 97 secured to the escapeinentarbor of the motor. This locking means is theretore substantially the seine as that hereinbefore described in con'nnction with the tire alarm mechanism. Ti 93 is provided with a lateral arin 98 which is provided with a shoulder at its'free end. A sprin 99 presses the shouldered arm of the arm 8 towardthe end of a pin 79 projecting from the end of handle 78 and also ie upper end of lever.

At the ceiiti'al stationa battery 100 is provided for the signaling circuit, and a battery 110 for thel controlling circuit. A controller 120, a regiater 13:5, ind a telephone 140 may also be provided tere.
I will'now trace the various circuits and point out the operation of the system. :flic signal circuit m'thepresent instance is a closed circuit beginning at the battery 100, through a relay 130, b wire 101 to telephone arni .141. contact iagcr 142, wires 102 and 10:1. o and through wire .t which cxtcnds to the tirst signal box, in this ease the police signal box. 'lhence by wire 10:1 the circuit extends to contact finger 152 which is in contact with arm 151 of telephone 150 within the police signal box. A. wire l10.* connects this arm with the frame aiid through the latter to the signal disks 'itt and 77, aiid through the various coittact lingers resting thereon, by the wire 1011 to wire l1, h v means o1' which the signal circuit is continued to the next box on the line, which, in this case, is the tirealarin box 10. 'llie wire 10T connects the circuit with the metallic frame 11 and coittinaes through tite latter, signal dink 20 and brush 21 to wire 10S which is connected to the wire C. By means of wire C the circuit returns to ,the central station and is coinplctcd by wire 109 which connects wire C with the battery 100.
When the telephone receiver 140 at the central station is lifted, the artn 141 will make contact with finger 142' lwt'ore'ln'eak-v ing contact with linger 142. '.lhua the tranennttcr 144 is thrown itito the circuit witlioitt disturbing the signal circuit. 'lhc rear end 145 of arm 141 is insulated from the rest of the arm and is arranged to be moved into contact with fingers 146 and 147 to connect one end of the telepltone receiver with the signal line. The other end of the receiver is connected through a condenser 148 with the ground at litt). 144* antl 1M designate the primary and secondary windings of an,
induction eoil. Similar parts of the telephonie apparatus are shown iii-the police aignal box which may. in the above dcacribed manner, he thrown into tite signal wire cir cuit und grounded ift 169 through n condenser 15S. 'Ihus thc two telephones are connected together through the signaling mechanism in thc hosenand tlirongli the .signal circuit without tweaking tite latter. The iiii'itii 'ciiu-iit shown for conncrting'the receivers with the ground through condensers farther. prevents disturbance of the butcome;
tcrjyv :arrcnt through the signal circuit. The Second or cont rolling circuit which may also be called the unlocking circuit is energized by a battery 110 at the central station. It is a normally closet] circuit which passes through a switch 160 and contact 161 to a high resistanccvrelay 165. Thence itl runs.
by a, wire D to the police signal box, in which it is connected bv wire 111 with convvtact: plate 84. 'This p atc is .connected by vbrush 823 with plate 85,and a wire 112 con-.
controller 120, wire 12:?,` linger 123, wheel' 124. finger 125, andwirc 116 to the battery.
,Vhen' the mechanism at u station i8 unrated to transt'nit a signal tocentral otiice, the various mechanisms will he con trolletl bv a cnt ubination of the circuits which l have above described. Before the box has been set for operation the releasing solenoid 30 is entirely cut, oli' from the rest of the system, as one of its terminals is connectcd with a dead contact 'ilate 87` and ita other teriuinal is connectet with another dead contact plate 214 and with the ground by conductor V11i'. When thc box is set for operation, the switch-arm -10 is moved to the left so that the tingcr lt ia moved otl from stationary contact it!) and into position to bridge contacts 38 and. 37. At. t ie. saine time stationary contact 3'1 is connected by contact blade 33 with stationary contact :15 which is connected with the wirt` 108 of the si 'nal ciiruitt. Thus the wires -113 vand 1'),
w iieh connected this box with thc'station litvanti it. are disconnected und a circuit. in formed of arts of tite igual circuit and thc control ing circuit which includes the ich-using solenoid 80 ofv the that tire alarm station. This circuit. froin hattery cxtends through switch 100 and its contact 102, wires'118, 109, t), 108, contacts 114 and 85 which are bridged by contact 33, to and through .nuignet 110, vcontacta 37 and 88, which are brid `d by contact 36, wires F and-115,1hroug i controller 120, anti by wire '116 back to the battery.
The switch 160 in'providetl ao that it a break should occur in the ai nal line, the ponton in charge of the centralzoliice niayby moving this l:twitch into the position indicated by dotted lines, unlock an box` or boxen beyond the break which may av been pulled` so that the latter will notl beeneatly end in ita igual aiv auch time as t ie break-is remitted which would obviously be too lateto of any use. .The break in the signal line would be 'indicated by the iioI relay 130 and thc register 133 and if any hor has been pulled on the line since the lncak occumad, this fact will be shown by the urination of thc controller 120 as soon as switch 100 ia thrown over.
lhc 'lenoid .'10 and the magnet 121 in the controller at'the central atation are arranged to act almultamaiualy, ao that. the mlclmid 30 will relcaee the algnalin mechauiem of the tiret tire alarm box an at the mme tune the magnet 121 will came the coutrollcr to he actuated to break the controlling circuit. 'lhia iu uccompliahed by the rotation of the dial: 124 b come untuble ucana which. when rctcur'et by the ma net .1 und its amiciutcd parts. will nalte ralf u revolution. thereby carrying lug 126 away from finger 123 an bringi it into the positiou .-hown in dotted linea in which-it ia in eontuct with linger 12T. und cnrrying lug 121i away from iiugrr 12? and into contact with linger 129. 'lhia will councct thc controller 1:20 and the rcgiater 125:1 together.
'l`hc rcsiotam'c of relay 16.'. in the control ling circuit is ao great. that the controller muguet ltl'will not actuate ite associated parte until the mntrolliug circuit beyond :my atatiou ia broken, time cutting the relay 106 dint ofthe circuit. 'lhia relay 105 would alao gire notice ct any break in the line through it-i hack contacta which are not shown in the dran-ingu but ia well known in the art.
After the aignal fromy a given station haa been ent in over the that or aignali circuit. the controlling circuit ia automatically restored and the controller 120 at the cmtral tation brought hack to ita normal condition. This reault is attained by the following circuit and arrangement of parte. Beginning at a local battery 185 Vthe circuit goce throu l wire 1311. arm 187, contact 188, wire lllll. t trough magnet lJ1.to linger 197, which. of cournc. rnuuot cioe' the circuit hcforc thc lug 120 wgietcra it: thcn `bv tin -r 1211 and wire 180'* hack to battery 131i. Wifilc thc rcgiatcr 1:13 is inventing magnet 183* keeps the arm 137 away from contact 138. thun keeping the above local circuit open until the register hea completed ita operation. Aa aoou an the above local circuit ia cloaed through magnet 121 the controller will he raleaacd thereby and will make an- -uthcr hal! revolution. thua returning the parta to their originnl positions and restormg thc controlling circuit throughout' the loymtcm.
'Il'lw mcchuuiem of the recorder 133 in well known und, as mund, in provided with an ceca|asnwut doi-icc or other retarder which prot-cute thcl closing of urm 137 against contact 1218 until the register mechanism has come to rest.
ln Fig. 2 the emential parte of the lice of its arm 174, pushes thc com of rele ns station 1. The essential parte of tire alarm box signal 43 are shown as station 3. Intermediate these two stations ie cnothor tire alurm signal box, signal 34,.
'any box is moved to energize ite releasing magnet, auch movement at puce cute ott the eontrollin circuit or releaamgcurrcnt from all succcei ing signal boxer on the line, and the controller at the eentra'l gtotion also o ns the circuit of the controlling line unti the signal ia received und the recorder a in comes to reet. Then, if one or more o the other boxes ou a liuc have lieen pulled or set for operation, the one of these which ia nearest the central station will take the signal circuit and eend in ita aignal. It in, therefore, poaaible to connect au unlimited number of boxes on one hna and they will he abaolutely non-interfering. For example, it there were one hundred igual boxea on one line and all were pulled at exactly the lame time, the .one neareat the central station would eend m ita signal and the other would remain locked until the ret. had completed ite operation. The next nearest box to central .tation would then take the line and eend in ita tlc. It, during the sendi of a aignal one of the boxes another x nearer central atation diould be pulled tbia would not. interfere with the signal w uch waa being aant, but after the completloncf auch the latter'aigual box would take the 'ne and aend in ita ai al followed in turn by the other aignal xee which had been let for operation.
