SPECIEICATlONformihg' part of Letters Patent no. 655,144, datedfiuly 31, 19001 Application filed May 14,1900.

To, all whom it may concern;

Be it known that we, OTTO P. YURGAEIand ROBERT H. YURGAE, citizens of, the United States, and residents of Milwaukee, in the county of Milwaukee and State of Wisconsin,

have invented certain new and useful Improvements in Electric Signal Registering Systems; and we do hereby declare that the following is a full, clear,- and exact descrip- Ic tion thereof.

Our invention has for its object to economically combine electric-signal-registering systerms with means for electric-telephone communication between call and main stations :5 of such systems, said invention consisting in what is hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a front elevation of combined signal and telephone apparatus embodied in a call-station instrument that constitutes part of ourinvention, the telephone-receiver being off hook; Fig. 2, a sectional View indicated by line 2 2 in the preceding figure; Fig. 3, a front elevation of a portion of the aforesaid apparatus,.partly broken, said telephone-receiver being hung on the main-shaft crank of a spring-motor such as is commonly employed in messengercall boxes of district-telegraph companies;

Fig. 4, a plan view, partly in horizontal section, on the plane indicated by line 4 4 in the third figure of the series; and Fig. 5, a diagram illustrating the practical working of our invention.

Referring by letter to the drawings, A indicates the back of an instrument such as we propose to employ at each call-station of a an electric signal registering system, and in practice a removable housing will be utilized to cover mechanism mounted on said back, the latter being provided with a ground-wire binding-post]; and other binding-posts 0 0 for a line-wire withwhich the several callstationinstruments are connected inseries.

Mounted onback A is the frame D of a springmotor, to which reference is had in the description of Fig. 3, and in accordance with our invention main-shaft crank E of this Serial No. 16,563. (No model.)

either direction being limited by any suitable means. When the number-wheel has rotation, its teeth contact with an opposing spring-metal plate H, constituting a conduc tor supported on insulation I,- attached to the motor-frame, Another spring metal plate or conductorH is shown surmounting the one H, for the most part parallel thereto; but in practice it may be a recurved continuation of same, these conductors being electrically connected with one of the line-wire bindingposts 0 of the instruments. Supported on insulation I and electrically connected with the other of the line-wire binding-posts O of the instrument is a spring-conductor J, that contacts with conductor H and an insulatingstud b of the motor-frame when crank E is depressed to full limit. Fast on the main shaft of the motor weshow an insulated lifter Kjfor the conductor J; but it is practical to have this lifteron the aforesaid crank, its function being to break connection of the opposing conductors when said crank hasupward throw incidental to removal therefrom of thetelephone-receiver for which it constitutes a hanger.

*In post connection with the instrument back ,-A we showspring-contacts L L, one of which is wired to binding-postB and the other to themotor-frame, whereby when these contacts are in touch the number-Wheel G is grounded. The motor-crankE being swung grounding of said wheel takes place the in-.

stant said crank-arm is permitted to ascend. While we have provided means for taking the ground 01? the number-wheel when the call=station telephone receiver is hung up, it is practical to have theground constant on said wheel. An electric-telephone transmitter M and an induction-coil M are included in mitter and primary of the coil, the secondary of said coil being put in circuit with the telephone-receiverF aforesaid. Oneterminal of a battery N at main station of the line is grounded, and the other terminal of the battery is wired to the electromagnet P of-a re-- lay, from which said line goes outthrough a post P, through the several call-station instruments, and returns to said post, the armature'Q of the relay, a register R, and a battery T being in local circuit. An electrictelephone apparatus at main station is in circuit with a battery U, having sufficient strength to overcome resistance of the linecircuit, the terminals of this battery, the

transmitter V of the telephone apparatus,

and opposite conductor-plates of a split plug W being in circuit with the primary of the induction-coil X of said telephone apparatus, the receiver Y of this apparatus being put in circuit with the secondary of said coil.

In connection with the line at main station is a'spring-jack Z for engagement of the split plug W when it is desirable to connect the telephone at said station with said line.

To signal main. station from any call-sta- 1 tion on the line, telephone-receiver F at the call-station is removed from its hanger, and

incidental to automatic ascent of this hanger the then rotating number-wheel is grounded, whereby it is apparent that the number of the call-station will be automatically registered atsaid main'station owing to intermittent contact of the teeth of said wheel with conductor H, whose practical continuation H said call-station having operated in the mean time to lift conductor J, so that the telephone apparatus of :this station may be effective. The caller can now converse with the mainstation. operator to impart or receive instruction or information, and the conversation being finished receiver F of calling-station telephone isagain hung on the motor-crank to thereby effect I an automatic cuttin g out of said telephone and the taking away of ground from the number-wheel of the signal-circuit,

From the'foregoing it'will be understood that all current necessary for the signaling and talking circuits is furnished directly from main station of the line, and under ordinary circumstances none of the call-stations on said line can have telephone communica tion of the calls.

current for talking-circuit become broken,

tion with the main station without-first registering the call-station number, nor does establishing of-the talking-circuit between one call-station and main station interfere with sending in of signal from any others of the call-stations on the line, and should it hap- ,pen that while one caller has the 1in'e other the call-station instrument, thecondu'ctors- H and J being put incircuit with saidtranse callers out in the-operator at--main station 'willtake the messages in ordenofregistra- Should the line furnishing short circuited, or otherwise inoperative, there will be no interference with the signaling 'of a call-station to main station, as either the out or in of the line and the ground will constitute asignal-circuit. In case the si nal-circuit becomes improperly grounded, so as to prevent registration of a call,,and, the 1 talking-circuit remain unimpaired commu nication between call andmain stationsmay station operator becomes aware ofthe'trouble and connects main-station telephone-with the liner It'is obvious that one main station- 'tele phone apparatus may serve" for connection with the talking-circuit of any of several independent call-station'lines, each of the latbe had on the latter circuit,'provided mainter being provided with its own spring-jack for engagement of the split plug constituting part of said apparatus.

Having thus described our invention, what we claim as new, and desire to se'cureby Let-1 tersPatent,isw 1. The combination of a main-stationbat tery and electricsigoal-register"apparatus, call-station instruments in series on a linein circuit with said battery andapparatus, each instrument comprising a number -wheel, a spring-motor for same, 'sepa-rableconductors intercepting :the line and arranged to have one thereof in yielding opposition to teeth of said wheel," a crank on a motorshaft movable in one direction to contract the motorspring, a device movable with the crank to separate said conductors coincident with expansion of I said spring, and an electric-telephone appa ratus in circuit withthe aforesaidfconductors, the motor-crank serving as a hanger for the receiver element of this apparatus;

means for ground circuiting the numberwheel with' the aforesaid battery, a main-stationelectric-telephone apparatus, a battery for same, and means for putting this telea phone apparatus in and "out of circuitjvith the line of call-stations.

2. The combination of, a groundedf maim station battery and electric-signal-register apparatus, call-station instruments in series on a line in circuit with said battery and appa mm, each instrument com prising anumber;

. wheel, a spring-motor for same, sep arable;con-

ductors intercepting the line and arranged to have one thereof inyielding opposition -to'teeth of said wheel, a crank on a motorshaft 'movable inone direction to contract the motor-spring, a device movable withthe too I to

' such thatseparation takes place incidental to descent of said crank; a main-station electric-telephone apparatus, a battery for same, and means for putting this telephone appa ratus in and out of circuit with the line of call-stations.

In testimony that We claim the foregoing 15 we have hereunto set our hands, at Milwaukee, in the county of Milwaukee and State of Wisconsin, inthe presence of two witnesses OTTO P. YURGAE. ROBERT H. YURGAEi Witnesses:

N. E. OLIPHANT, B. O; RoLoFF.
