and front contact of relay 12, conductors l 9 and 20, stepping magnet 17, to grounded battery. Magnet 17, on energization, attracts-armature 21, moving a stepping pawl 22. The pawl 22 moves a ratchet wheel 23 one step, carrying an arm 24 one step, bring ing said arm to rest on a contact leading to operating magnet I, controlling a counter 26individual to party Iof the. calling line. The arm 24 is held in this position by a locking pawl 27 which was placed'in locking position oirenergization of the relay 12. The relay 16 was energized at the same time as magnet .17. over a circuit. common with that of said magnet, through theconductor 19, from whence a conductor 28 extends the circuitto relay 16 and grounded battery. On the firsttmovement of the arm 24, of?- normal contacts 192 and 193 were closed but the energization of relay 16 prevented shunting of the relay 2 by opening the line On the circuit originated: by the senderl be.- ing momentarily made and momentarily broken, stepping magnet 17-is again actuated to move its arm to contact 29 and the next energization of the relay 2 with the subsequent momentary deenergization will move arm 24 to contact 30, while still another will move it to contact 31 extending to the operating magnet'IV of the counter individual to party IV. The circuit through the magnet 2 is then completed for-a longer interval and its armature held up su1liciently long forthe relay 16. to be de'e'nergized, whereupon its armature will close a circuit shunting out the relay 2 over the following circuit: ground, contact spring of sender 1, conductors 3, 4 and 5, 32,. armature andback contact of relay 16,.conductor contact,192, conductors-"34, 6, back contact andleft-hand armature of relay 7 conductor 11 and line relay 10 to grounded battery. Line relay l0 pulls up, completing a locking circuit'for itself from ground, conductor 35, throughits. left-hand armatureand front contact, conductors 36,- 6, back contact and left-hand arn'iature of relay7,

conductor 11, relay 10, to grounded battery, Theline signal is nowilluminated at full brilliancy, the high resistance relay2having been shunted from its circuit. .The relay 10 also maintains a circuit for the energization of the releaserrelay. l2 over a c1rcuit from ground, right-hand armature and.

front contact of relay l0, conductor 37, con tact 193, conductor 15, relay 12, to grounded battery. The sender will have reached its normal position by this time, removing any possibility of further ground therefrom.

The subscriber will have removed 'his re-- ceiver prior to this time. and the line signal 9, being new fully illuminated, will attract the attention of the operator, who will take the answering end of an idle cord and insert theplug 38 thereof into the jack 39 to which the conductors of the calling line are secured. The cut-off relay 7 is actuated over a circuit from grounded battery, relay 7-, conductor 40, sleeve contact of jack 39, sleeve ofthe plug 38, resistance 44, conductor 41, registering key 42, in its normal position, to ground! lmmediatelyupon pulling up, the relay 7 completes a maintaining circuit for the release relay 12 over a circuit extending from ground, right-hand armature-andfront contact of relay 7, conductor 37, contact 193, conductor 15, relay 12, to grounded battery. Relay 7, on pulling up, also opensthe circuit of the line signal 9 and also the circuit of theline relay 10 which thereupon'falls back. A circuit is also completed for the operating magnet IV from grounded battery, operating magnet IV, contact 3l, arm 24, conductors 43. and 40, test contact of jack 39, sleeve of plug 38, and through resistance 44 of conductor 41, and registering key 42, inits normal position, to ground. The magnet, however, will not pull up at this time as it is-so'made that it will not operate through the battery normally associated therewith, but requires a stronger battery for operating.

On the operators pressing the listening key 45, she connects in an operators set 46, and the talking circuit of the subscriber is new extended over the conductors 4 and'47 through jack 39 and plug 38, and conductors 48 and 49 of the answering part of the cord and a repeating coil to the conductors 51- and 52 of the calling end of the cord and through listening key 45 to the operators set. The operator can now converse with the calling party. The operator would then use the calling end of her cord to extend the calling line to the line called in the usual manner. Magnets 53 and 54 in the conductors 48 and 51 would control. the supervisory signals of the calling and called parties, respectively, and 011 the operators learning that the called party has responded, the registering key 42 would be depressed and furnish added battery 50, which, acting in series with the battery of the operating magnet IV, would cause it to pull up its armature and step the counter associated therewith one step, thus registering a successful call. The particular cord circuit used forms no part of the present invention, as any cord circuit could be used which has a sleeve with a registering key normally. grounded,and which, when operated, would connect a battery in series with the battery of the operating magnets.

On either partys hanging up, this fact would be indicated to the operator by one of the supervisory signals 53, 54, whereupon the operator would pull down the cord. Relay 7 would then be deenergized, opening the circuit tothe release magnet 12. Release magnet, on being de'e'nerg-ized, allows the holding pawl 27 tobe Withdrawn from engagement with the wheel 23, whereupon the M11124 willbe returned to normal bya spring attached thereto.; The oil-normal contacts would nowbe open a'ndthe-device ady u que u e 1 i Referring now to theapplicati'on of this invention to a full automatic telephonesystemas shownin Fig. 2-o the dra ingS Afl A Atand represent subscribers sets on the same party line, the substationci'rcuit being shown for A whichwill be assumed to be party IV. Associatedwith each set is a sender mechanism 101 arranged to send a preliminary series of impulses on removal of the receiver and actuation. of a, preliminary sender. The number of impulses sent ditl'ers according to the station of the party line and acts to connect the proper counter with the calling line. Two sets of contacts are shown in "the sender, one being under the control of a preliminarysender, and the other set being underthecontrol ofthe subscriber in settingup the call. A type of sender which could be used torthis purpose is more fully describedin application of L. Goodrum and L. Von Nagy, Serial No.

94,846, filed May 1, 1916, and, reference is made thereto for moredetailed description The invention is not limited to use with this type of sender,.however, as any sender which will sendimpulses differing r01- the station of the partyline at which-itis used, maybe utilized. The diflerent I subscribers; in the same party line come: intoan exchange over common line conductors, as 103 and 104, ex-

tending respectively through the inner left-z hand armature and back contact, and the, righthand arniatureand back contact oi-a cut-oi? relay107. A conductor 106 extends from the back contact of the inner left-hand armature of relay 107 through line relay to ground. Removal of the; calling; subscribers receiver. completes a circuit from ground, leftehand WlLCllllg of relay 105,- con;

cuit for a slow release relay 112,. over a circuit from ground, armature and front .contact of relay .l09, conductor 113, relay 112, to grounded battery. Relay 112 pulls up, preparing a circuit for a slowrelease relay 10$,anda stepping magnet of the registering mechanism. Preliminary impulses are now; sent and, on the first break, relay 1091 is deenergized and its armature falls back, completing a circuit-for the relay .108,

extending fromground, arl nature andfiback contact of relay 109', armaturejand front'con-z tact, of relay 112, (slow to. release), conductor 114, relay 108-to grounded battery. Re-

lay 108 pulls up opening a part ofshunt f circuit aboutthe relay: 109.. A circuit was also. produced for the stepping magnet 1'15, extending-from conductor 114 of the circuit previously traced, conductor .116, stepping magnet I15, tojgrounded battery. ,Magnet 115being energizedgattracts its armature- 117, carrying a pawl :118 engaging'a ratchet Wheel119t0 movethe: same 'one step. The

ratchet wheel 119 carries anarm 120, which tacts 122, 123 and 124 arecont acts associated respectively with the operating magnets II IIL andIY of the counters, individual to party lines -II,.III, and IV. The arm is held intheposition to, which it is moved by a holdi1ig3pawl 125.1 Theoperating-mag nets control the counters by attractingan armature 126 carrying a pawl which steps counter wheel 127 one step on each -'operation.

7 Three other ,inomentary interruptions [or the circuit are produced by the sender 101 and step the arm 120 to position the. same on the contact 124. The relay 109 pulls up;

Operating magnet IV will not pull up-a-t this '1 time,-due to the combined resistance of line switch magnet 133, cut-off relay 107 and relay 143 in series therewith; 'ltelay 143, on energization, completes a circuit from ground, front contact and armature of relay 143, conductor-179 to switch 146, which controls a circuit for moving the master switch With other idle plungers to a'rposition ready for association with the next idle trunk. Cut-off relay 107 is energized and pulls up, extendingthe calling line to a trunk selector by a circuit extending from ground, armature and back contact of relay 145, conductor 144, relay 143, conductors 142, 141, contact spring 137, conductor 140, front contact and right-hand armature of relay 107, conductor 104, subscribers set, conductor 103, inner left-hand armature and front contact of relay 107, conductor 147, contact spring 136, conductor" 148, and an arm 149 of the selector side switch in its first position, conductor 150, and relay 151, to grounded battery. Relay 151 then pulls up, completinga circuit for a slow release relay 152 extending from ground, armature and back contact of test relay 153, armature and front contactof relay 151, conductors 154 and 155, and relay 152'to grounded battery. Relay 152 on energization prepares a circuit for the rotary or primary stepping magnet 156 and also for a slow release relay 157.

The calling subscriber then operates his sender to set up a call and on each interruption the armature of relay 151 falls back, completing a circuit from ground, armature and back contact of relay 153, conductor 158, left-hand armature and front contact of relay 152, conductors 159 and 160 to the rotary magnet 156, which rotates the finder brush the number of steps corresponding to impulses set up by the subscriber. The'relay 157 is energized over a branch circuit extending from conductor 159 of the circuit previously traced, conductor 161, and relay 157 to grounded battery. Relay 157 pulls up, completing a circuit from ground and its armature and front contact, conductor 162, through side switch escapement magnet 163. This magnet 163 remains energized until the rotary impulses have been sent, whereupon relay 151 is energized sufiiciently long to let the slow release relay 157 drop back, deenergizing relay 163. On this deenerglzatlon the c1rcu1t control switch arms are moved to second posltion,

Immediately upon going to second position, a circuit is completed from ground, armature and back contact of relay 153, armature and front contact of relay 151, conductors 154, and 164, side-switch arm 165, at second position, conductor 166, rear contact and armature of the vertical magnet 167, to grounded battery. The magnet 167 interrupts its own circuit and steps. the

the conductors 168 and 169, encounter an idle trunk which is represented by the presence of test ground upon its contact 170'. As soon as an idle trunk is reached, a circuit is completed, energizing'the test relay 153 by a circuit extending from test ground contact 170, brush conductor 169, conductor 171, relay'153, to grounded battery; Relay 153 pulling up completes a circuit-for the escapement magnet 163, extending from ground, armature and front contact of relay 153, conductor 172, right-hand armature and front contact of relay 152, which is slow to release, conductors 173 and 174, and escapement magnet 163 to grounded battery. On this energization,'tl1e escapement magnet moves the side-switch arms to third position.

In the third position, the test ground is removed and relay 153 deenergized by the operation of the next switch (not shown) in the Well-known manner. The call would now be put through selectors and connectors until the called party 180 was reached and would be rung in any desired manner, such means not being considered any part of this lnventlon. In this position, a polarized relay 175 has been placed 1n a circult, so that on the called partys removing his receiver,

a circuit having a polarity such as to operate the polarized relay 175 would be completed from grounded battery, relay 153, conductors 171, 169, called subscribers set 180, conductor 168, polarized relay 175, conductor 176, circuit control switch arm 149, co'nduc-' tor 148, spring contact 136, conductor 147,

front contact and inner left-hand armature the resistance to such an extent that'the opcrating magnet IV would pull up,actuating its counter 127. This circuit extendsfrom ground, inner armature of polarlzed relay 175, conductors 177, 141, contact spring 137,

conductor l40,-relay 107, conductor 139,,

right-hand winding of magnet 133, conductor 138, arm 120, contact 124, and operatingf magnet IV to grounded battery. A circuit is also completed for the escapement magnet 163, extending from ground, front contact and outer armature of polarized relay 175, conductor 178, front contact and armature of escapement magnet 163, conductor 174, and escapement magnet 163, to grounded battery. The escapement magnetpulls up, interrupting its own circuit, and steps the circuit control switch arms'to the fourth rect current. V

When the called party hangs up, ground I is put on test terminal l7O, cInpleting a'c1r- 'cuitfor the test magnet, "This' circ uit extends/from gronnd, li Oyover conductors 169, l'7l,' through rel;ay 153 'to grounded battery.
