- Application filed April 15, 1905, Serial No. 255,832. Renewed December 31, 1910. Serial No. 600,279.

To an whom it may concern v Be'it known that I, EDWARD E. CLEMENT, a citizen of the United States, residing at Washington, in the'District of Columbia,

have inyent'ed certain new and useful Improvements in Telephone Registering Systems, of which the following is a specification, reference being bad therein to the accompanying drawing.

My invention relates to telephone systems, and has for its object the production of a registering system for use in connection with the telephone circuits.

The desirable features to be attained are the following: a record of the particular operator who handled aparticular volume or business; a record of each call made and of each call answered by the called subscriber; and if desired a record of the length of time elapsing between the call and the connection, the latter and the answer by the called subscriber, and during the conversation. The importance of these records will be perfectly apparent to every traific man,-

which connection has been made. A number wheel during this operation has been turned so that the number of the connected line is automatically brought opposite a printing platen, to print the number. Each operator is provided with a distinctive key inserted, when she is on duty, in a switchboardopening, and sending makes and breaks corresponding to the operators number, to set same in printing position.

The'fi details of my invention will appear from the follmving descriptionand claims. Myinvention illustrated in the accompanying drawings, whereinan auxiliary printing wheel to bring .the

I two wire multiple.

Figure 1 is a diagram showing two sub scribers" line-circuits and a central office connectmg clrcult, with a registering device attached thereto. Figs. Q'and 3 are de of the tape feed mechanism.

Referring to Fig. 1, A and A are two subscribers stations shown as connected to a multiple switchboard wired up in accord ance with a well known standard scheme of Each sub -station is equipped wlth apparatus usual in'common battery systems, which consists of a transmitter T, receiver It, hook H, ringers Q, and condenser C. The line-wires-from the two sub-stations terminate in a central office in similar apparatus, and therefore only one need be desc'ribed- The line-wires 1 and 2 normally extended, the first to the line-relay M and the second to ground. \Vhen the relay N is energized the line-wires 1 and 2 are extended through to the contacts y', .jof the answering-jack J by the wires 3 and 4a. The cord-circuit consists ofthe answering-plug P, whose tip 79 is connected to the tip of thecalling-plug P by the strand 7, condenser C, and strand 9. The sleeve p of the 1.)lug P is connected to the sleeve p of the plug P by the strand 8, condenser C andstrand l0. Bridged across the strands 7- and t3 is a pair of supervisory relays S, S, which Jointly control the supervisory lamp 8. Bridged across the strands '9 and 10 are the two supervisory relays S and S jointly controllin the lamp s All of the arrangement so far described is old and well known, having-been largely used in common battery installations. I have shown my invention in connection with this circuit because it happens to be aconvenient system for illustration; but I do not wish to be limited thereby nor am I limited in practice to any particular type of system. My invention is well adapted for .any of the common battery systems now known and used.

'. Y The type of switch I havechosen to illustrate isthat employed 'quite commonly in automatic exchange systems according to present practice. Its essential features are a spindle carrying a contact wiper and rotating to move said wiper over a series of fixed contacts arranged in a circle having a greater or smaller dimension according to the number of contacts. The circle with its contacts is called a bank or contact bank. The spindle is rotated by means of a ratchet wheel mounted on it and a pawl vibrated by an electro-magnet. This spindle has no idle or normal position, that is the wiper can rest on any contact, for when the switch itself is idle there is no connection of any kind with the wiper. Mounted on the spindle is a type wheel fixed so that when the wiper rests upon any particular line-contact the number of that line on the type wheel will ing a multiple contact in the bank swept over by the wiper a Directly under this practically will be in practice horizontal.

'On this spindle is mounted a collar a, carrying the wiper 2 which extends out radially was to sweep over the circle of 'contacts as the s indlerotates. At the upper end of the spin le is a type wheel D, bearing on its periphery type numbers or characters raised in relief, there being a number or character on the wheel corresponding to each line havtype wheel there is another type wheel D",-

, bearing on its periphery characters or numerals'corresponding to the number of the operators occupying the position. Opposite t e'two type wheels is a printing magnet W shown as a solenoid magnetwith an iron shell and a central plunger carrying the .armature 'w at one end and the rintin Z3 5, and the shaftor arbor o WI-he' 1 platen to at the other. Between the platenv and the type wheel lies the tape w fed from a roll .or spider X, as shown above the wheel, down between the friction or feed rolls w and 20 The feed of this tape is governed by the printing magnet. As I have illustrated it for simplicity, this is accomplishedby meansfof a spring extension arm to attached tofithe armature and provided with a hook ort'oe which catches into teeth on the peripherypf the feed-wheel This may work in either of two waysyb oth of which would be'well enough,represented) diagrammatically as shown. First, it may be that-the toe on the arm we, when the armature. is retracted, will pull the whee w around several teeth depe'ndingfon: ,th space of the air gap allowed the;magnet' NV thus feeding the tape a space after ber is printed a second v time. *S ejc toe may be merely a detent, as shew One termi driven shaft, that is, provided with a motor as clock work, the speed of the shafts rotation being redetermined and constant. In this case a ter the printing magnet has done its Work and sli htly retracted its armature so as to free the tape from pressure, the latter -will be continuously fed until the printing circuit is broken at the end of a conversation. On the retraction of the armature the detent will prevent further rotation of the shaft. The length of the tape fed will thus be a measure of the elapsed time after the number was stamped and furnishin means for getting totals of time use of su scribers lines.

The circuits of my switch are very simple, and the connections to the cord and line-circuits are made without altering or interfering with any of their parts. Taps are taken oif the sleeve side of each line and carried to the multiple contacts in the switches of its particular position, there being one switch to each operators cordcircuit. A tap isalso taken from the sleeve side of the cord-circuit, as well as one from the back contact of the calling supervisory relay. These three taps are the only necessary wires to be connected, one tap for a line and two for a cord-circuit. The tap from the back contact of the calling supervisory relay supplies current through the wire 13 to t 1e magnets W and \V when the calling plug is inserted, and it may also be used'for the supervisory lamp 8 but in that case the l lamp and the magnets must be of such resistances that they will not operate on the small normal leakage through the wires .18

and 14. In practice the tap for the lamp is taken from a separate contact, so that the wire 13 is normally ungrounded.

Referring now to F 1, the sleeve side of the line No. 4L is connected in multiple to the contacts of the switches in its position by the wire 30. The sleeve 8 of the answeringplug is connected to one terminal of. the

relay 8*, the other terminal of whichis connected to battery by the wire 12 through the contacts 8 and s of the relay S. The contact 8 of the calling supervisory relay S is connected to the magnet lV by the wire 13, the other terminal ofthis magnet as well a-s'one terminal of themagnet W is con- .nected to-the contact of, the relay S by the'wire 16, the otheri 'tcrininal of the mag- -net jl/V;being connected, to battery through fillle fintilgcfis s -fand sftof the relay S". One terminal a of (the grounded, the,

otary magnet S is er terminal being conlejctedntov thejc i'tact s of the relay S. fol the rotary or interrupting connected to the contact 3 ay 8 .1 One terminal of the relay S the contact 8 are grounded, the other t 1 ers nd "terminal being connected to the contacts 8 s of the relay S by the wire 17. K represents an operator s key similar to'those used 1n connectlon with the time clocks, as

used in factories for registering the time of.

ferent numbers of projections or teeth.v

This key operates and registers the 0 eratorls number on the tape as followsrW en placed in ,the jack it makes and breaks the contacts k, is, according to the number of projections, on the edge of the key. These makes and breaks operate the magnet S which causes the sleeve a carrying the number-wheel D to rotate the number of times corresponding to the number of teeth'of the key. This brings the operators number"/on the number-wheel opposite the tape, when the printingmagnet W is operated itlstamps the operators number as well as the number of the line on the tape. The key has a long shank,and when first inserted closes the contacts 70 and 70 which in turn 'close the circuit, of the release magnet S. This magnet attracts its armature and engages the sleeve .2 acting as aretaining awl. When the operator leaves the positlon, she withdraws the key K and opens the contacts 70 ,72 releasing the magnet S", which thereupon releases the sleeve 2 which is then carried to its normal position by a suitable tension spring.

The operation of my system is as follows: Subscriber A in calling closes the circuit of the line-relay M through the contacts of the cut-off relay N, closing the local circuit of the lamp m, which glows. The operator upon perceiving the signal inserts the answering-plug P into the jack J The windings'of the relays-S" and N are now connected in series. The relay N' becoming energized attracts its armatures, disconnects the line-relay M which in turn exti'nguishes the line lamp m. The line-wires 1 and 2 are now connected to the springs 7', j, of the jack J, through the contacts of the cut-off relay N and the extensions 3 and 4c. The relay S, becoming energized attracts its armature and would cause the lamp 's 'to glow, but the relay S becoming energized also attracts its armature, opening the lamp; The relay S of the register is connected to the strand; 8 by the wire 15 and circuit.

is-in parallel with the relay S, so therefore becomes energized and attracts'its arma-' tures. The closing of the contacts s 8", closes the circuit-of the relay S WlllCll becoming energlzed attracts its armatures,

breaks the contacts 8 s and closes the contacts s" and s, which disconnects one terminal of the relay 5* from battery by breaking contacts 8 8 andconnects 1t to .the Wiper aflby closin contacts 8 -8", this closure occurring eit er before or simultaneously with the break. The contacts 8 ands are closed, and the terminal of the relay S leading to strand= 8 ,is connected directly tobattery and relay S is. thereby shunted. Thecut-ofi relay N is now held energized by battery direct by the following path: battery, wire 12, contacts 8 s s 8 wire 15, strand 8, v3r), j, wire 4:, relay N to ground. The relay 8 is now kept ener- 'gized by the wiper a which passes over the contacts 2 as the spindle z is turned by magnet S, which is energized by the closing of the contacts 8", 8 to connect the interrupting machine G to the Wire 19. All contacts z are grounded through theirrespective cut-off relays. This circuit of mag net S is then as follows: B, 12, 8 s, 8 8 15, S", 8 s", 21, 2 2 30, N, and ground.

This spindle will continue to rotate until the wiper e which closes on each contact before breaking the preceding, comes into connection with the contact leading 'to'the line in which the plug is inserted. The instant this happens the relay S becomes sh'ort-circuited or shunted by the following circuit: wire 4, j, p, strand 8, in which there is practically no resistance, in comparison with the following circuit: wire 30, 2 .2 21, s 8 S and 15 to the wire 8, also from point 15 to contacts ,S ZLIId s thence to contacts 8 and s, and thence by Wire 12 direct to battery. The relay S therefore being shortcircuited becomes deenergized, opens the contacts s 8 removing the short-circuit from the relayS, allowing its winding to be in series withthe relay N. The contacts 8 s are broken, disconnecting the interrupting machine, which causes the spindle to at once come to rest. The relay S is held energized after the relay S has become deenergizedby the following path: ground, S wire 17, contacts 5 and 8 wire 2-3, contacts 8 s wires 20, 21, wiper 2 contacts 2 wires 30, 4:, and 8, and to battery through the winding-of the relay S;

printing the number'of the line connected and also the numberof the operator. 'When the operator completes the connection by placing the calling plug P into the jack J and ringing inthe ordinary manner, the following conditions are effected The relay 1S and the relay N are placed in series. The

relay N in attracting its armatures disconnects the line-relay-Mi" and connects the called line to the springs j, j of the jack J. The relayv S attracting its armature closes the circuit of-the lamp 8, causing it to glow. It also closes the circuit of the magnet W, which-attracts the arm w. The circuit of magnet WV is as follows: B, l2, s, s", s, s, 13, W, 16, 8, 8 and ground. When; the called subscriber answers, the relay 8* becomes energized, ex tinguishing the lamp .9 and at the same time releasin magnet W. This magnet when denerg'ized releases the arm 'w,"which comes in contact with the tape w and prints a character or number, or it can perforate the tape as may be desired. This distinguishing mark on the tape opposite the number of the line calling gives a record showing that the called party has answered. In case there should be no distinguishin mark opposite the number, it is an indication that the called party did not answer. We now have a record on the tape showing the number of I the calling subscriber and the number of the operator, and a mark showing that the called subscriber has answered. At the end of the conversation, the subscribers in hanging up their telephones open their respective line-circuits and deenergize the relays S and S causing the lamps s, s to glow. The operator noticing these signals takes down the connection, and the eut-ofi' relays N, of both subscribers lines, become deenergized, and cut on their respective line-relays and disconnect the lines from the jacks. The relay S of the register being now deprived of its current supply, through the relays, becomes denergi-zed. The relay i5 is again connected to battery through the contacts s 8 and the breaking of the contacts 8 s and leaves the .wiper 2 free from all connections, so that it can rest on any contact without causing interference of any kind. The contacts 8 and 8 being broken, the printing-magnet l/V becomes deenergized and the arm w in moving back to -i ts normal position engages the friction wheel to, causing it to move a short distance, which in turn moves the tape to allow for the next number being printed.
