-iECTRIC REGISTERING SYSTEIYI.

To all whom it may concern Be it known that I, HENRY Hovmnn, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Registering. Systems. of which the following is a full. clear,

concise. and exact description.

This invention relates to registering and recording mechanism. more particularly for registering mechanism which may he employed in telephone systems.

The object of this invention is the provision of means which will accurately register or record signals resulting from rapidly re curring; current impulses.

ln accordznice with the general features of this invention there are provided two sets ot relays responding to the current impulses constituting the signals. one set oi said relays being designed and adjusted to release quickly and adapted to release upon the break of the impulse circuit; the other set of relays being designed and adjusted to energizo very rapidly and connected in circuit to operate from the closure of the circuit. These sets of relays control the operation of a group of controlling relays, which group of relays in turn control the setting of the registering and recording deto the means which controls the setting ofthc registcriiur mechanism.

An impulse transmitter suitable for use in the ])I'&"'-2l' system is disclosed in applicants Patent. o. 1,271,164. issued July 2, 1918.

The wgistcrin or recording mechanism which will hereinafter be referred to as the and which is generally designated the drawing, consists of av shaft 1 Specification of Letters Patent.

Application filed April 26, 1917.

mounted in any suitable manner for rotation. At one end of this shaft and extendin; at right angles thereto, there is secured an arm 2 which. when unrestrained. moves in a clockwise direction under the control of the spring 3. The arm 2 is held in its normal position by a latch member 4 pivotally mounted at the free end of the arm 54. The latch. member -lis normally held. in alinement with the arm by av spring member. This latch member is provided with an arm 5, which engages a hook (3 of the armature ot' the magnet: 86 to hold the arm 2 in its normal position. For controlling the setting of the arm 2 there are provided five rods Each of these l'()(l is substantially similar in structure and operation. so it will only be necessary to describe. the structure. mounting, and operation of one rod, for example, the rod 12. The rod 1:2 is mounted for rotation in any suitable manner, and near one of its ends is provided with a. riulit1-angular pin 13. This pin operates in the bi-- fureated extension of the pivoted armature 14-, which is mounted for actuation under the control of either of the magnets 15 or 16. \Vhcu the magnet 15 is eueip'ized it attracts its armature to move the pin 13 in a downward direction. This causes the rod 12 to rotate in a counter-clockwise direction. \Vhen. however, the magnet lt is encr ized. it attracts its armature to more the pin 13 in an upward direction. This causes the rod 12 to be moved in a cloclnvise direction, as indicated by the arrow. The rod 12 is provided with a plurality of stops. two f r each register: these stops areindicated at l7 and 19. It will be noted that stops 1? and 1 are out. of alinement. An :ll'(-filltl}7etl menu her 19 provided with ratchet teeth on its inner surface is ciug'a red by dog 20 on the latch member l to hold arm 2 in actuated position as will be further described in the operation of the system.

Mounted on the shaft 1 of the register. there are secured a. plurality of contact con trolling devices of the structure and arrangement of the sequence switch disclosed designated 8, 9. 10, 11 and 12. e

indicated at 102,

inv the patent to Reynolds and Baldwin 1,127,808. These contact elements of the registers R R and R are diagrammatically 103 and 104, respectively. These registers may be restored by power driven means as in the above noted patent.

With this brief description of the apparatus it is believed that the invention will best be understood by setting up a number on. the registers shown. Let it be assumed that the desired number which is transmitted from the dial switch at the substation apparatus is the number 109. When the subscriber removes his receiver from the switchhook, the hook-switch springs 21 and 22 are closed. As soon as the receiver is removed from the switchhook, the line finder wnich indicated by the brushes 2? and 28 is operated in the well-known manner to seize the terminals 29 and 30 of the calling line. As soon as the calling line has been Located, a circuit is completed from ground, through the winding of the relays 23 and 24 in parallel, conductor brush 28, terminal 30, switchhook springs and 21, contact 31, shunting spring 32, transm'ittcr winding of the induction coil 34. impulse spring contact 36, terminal 25! of the calling line, finder brush 2?, armature and back contact of the cut-off relay 38, armatures and back contacts of the relays c c c c 0, 0, 0 w, 0", lower winding of relay 40, t0 grounded battery, where upon relays 23, 24 and 40 are energized. The relay 23 at its loft-hand armature and front contact completes a circuit from grounded battery, Winding of the relay 38,

contact and left-hand armature of relay finder brush 27, terminal 29, contact 36, im pulse spring 35, winding of induction coil 34, transmitter 33, shunting spring 32. con tact 31, switchhook springs 21 and 22, terminal 30, finder brush 2S, conductor 27 Winding of relay 23, to ground. Al the rigl'it-hand contactand armature of the relay a circuit is completed from ground, conductor 41, armature and back contact of relay 42, winding of the relay 43, to grounded battery. The relay 43 attracts its armatures and at its left-hand armature and front contact completes a circuit from ground, conductor 44, right-hand armature and back contact of relay C", right-hand Winding of relay 0, to grounded battery, and similar parallel circuits are com lcted through the right-hand armatures am back contacts of the relays C", C", C and C. to grounded battery, through the.

right-hand windings of relays 1;, c c", r;,

0", c 0 c. The last-mentioned relays are energized in these circuits.

As soon as the dial D is moved, the circuit through contact 31 and shunting spring 32 is opened, and a circuit is compteml through contact 45 and shunting spring 32. The closing of the circuit through contact 40 and shunting spring 32 includes the resistance 46 in the energizing circuit of the relay 23. The relay 23 is marginal and does not rcmam energized in series with resistance 46. When the dial is moved farther, the circuit completed through the contact 36 and spring 35 is opened, but the relay 24 is slow to release and does not dcenergize during the momentary interruptions of its operating circuit. The dei nergization of relay 23 causes relay 38 to release and also causes the shunting circuit about relay 42 to be broken. The relay 42 is energized over a circuit extending from grounded batter windings of the relays 43 and 42, right-hand contact and armature of the relay 43, front contact and armature of relay 24. to ground. WVhen, in the operation of the dial, the spring 35 engages the contact 36, a circuit is closed from ground, winding of relay 23, conductor 25, finder brush 28, terminal 30, switchhook springs and 21, resistance 46, contacts 32 and 45, spring contact 36, terminal 29, brush 27, armature and back contact of cut-off relay 3S, armature and front contact 01 relay c and winding of this relay to grounded battery and in parallel through the left-hand winding of the relay C to grounded battery. Relay C attracts its armaturcs and at its right-hand armature and back contact interrupts the holding circuit of the relay 0. Atthe righthand contact and armature of relay a holding circuit is closed for this relay which may be traced from ground at the leftehand armature and front contact of relay 43, conductor 44, right-hand armature and front contact of relay C, contact 62, spring 61, resistance 93, to grounded battery. Since the relay is marginal it will not energize while resistance 46 is connected in this opcrating circuit. When now the dial is operated to again interrupt the circuit through contact 36 and ix'npulse spring 35, relay n will retract its armature and at its back contact will extend this circuit to the relay 0'. At the close of the series of the. impulses corresponding to the first digit, the dial will return to its normal position to close the contact 31 and shunting spring 32.

\Vith the contact 31. and shunting spring 32 in engagement, the resistance 46 is shuntcd from the operating circuit of the relay 23, causing this relay to energize. The. relay 23 attracts its armatures and completes a circuit from ground, its right-hand armature and front contact, conductor 41, armature and front contact of relay 42, contacts 20 and 47, winding of relay 48. to grounded battery. Relay 48 attracts Its armatures and com'nlctra a l\) 'iiiz|.f circuit for i sel from its (1 c c, c and c are menses front contact and left-hand armature over the remainder of the circuit just described. l Vhen. the relay is energized circuit is completed from grounded battery, arnni'l'ure and Contact d9 of this relay, Winding of relay 50, conductor 51, leithand armature and front contact of relay (1*, ture and back contact of relay C, conductor 44-, left-hand front contact and n-rnniture of relay 43, to ground, when relay fill is energizecl, to rotate the rod M in a cloc Wise direction.

The magnet attracts ture and in so doin disengages H e book 6 from the hook 5 ol the latch member, allowing the arm to rotate until it engages the stop inen'zber 51'. As soon as the latch member 41 engages the stop or pin 57, since the latch member pivotally mounted on the arm 2, the pawl 20 is thrown into engagen'ient .with the teeth of the ratchet mem r 19.

The relay (30 when it attracted its armature opened the holding circuit of the relays C and (l at contact (32 and contact spring (51. Al the left-hand front contact and arimiturc oi relay the energizing circuit of magnel if) is opened, causing this magnet to dci ncrgizc and pcrmit the roll 54 to return to its normal position. Vihcn the rod returns to its normal position, the energizing circuit of magnet 55 is opened at contact spring to cause the magnet 55 to dei nergize. When the magnet 55 deiimergizes, the contact spring 58 discngages its contact to open the energizing circuit of the relay 60. At the time that the relays C and decnero'izcd they completed circuits at their right-hand armaturcs and back contacts for rei ncrg'izing relays c and c. The relays are now in the following condition: relays 4-2. -13 and i3, relays 23 24;, cut-oil relay-13R, the relays o, o. n-' ("'2 cnrrgizcd.

On operating the dial to transmit the inipulses corresponding to the second digit of the desired number. which zero, the shunt ing spring 32 and its contact 31 are diseir rightdiand armaits armaand gaged and the impulse spring- 35 and its contacts 36 are also disengaged. ("unsure the re lay 23 and the cut-oll' relay 38 lo release.

The relay 23 at its right-hand armature and front contact interrupts the actuating circuit of relay 48, allowing it to release. When now, the impulse spring 35 engages its contact 36 the relay C will be energized.

n releasing the dial, shunting spring 32 will engage its contact 31, to short-circuit the resistance 16, and cause the relay to operate. It Willbe remembered that the register R is in position 1. lVilh the reg-is for R in position 1 and relay 23 energized a. circuit is completed from ground, conductor 41, armature and front contact oi rclav -12, armature and back contact of relay contacts 64 and (55, contacts 67 and 6h, winding of the relays 69, to grounded lmttcry.

The relay lb attractsits armature and by .so doing rolates the rod 75in a clockwise direction. Simullancously the magnet 71 is actuated to release the arm 2. The arm 22 rotates until it engages the posi tioned stop 76. The energizingcircuit of magnet 71 extends from grounded battery. contact 101, winding of magnet 71, conduc for 90, contact and conlact spring 73 to ground. When the magnet '71 attracted its arnnlture, the contact spring 7S) engaged its contact and closed a circuit from grounded battery, conductor 59, winding of the relay 60, contact spring (31, contact 62. right-hand winding of relay C right-hand front coin loci and armature of this relay, conductor ll, left-haml l'ronl' contact and urn'iaturc of relay -13, to ground. Relay (90 again at tracts its armature and thereby completes a locking circuit for itscli' from ground, resistance 63, upper armature and contacl spring 1, winding of the relay 60, lo grounded battery. Relay ($0 when it attracts its arn'iaturc causes the decnerg'ization of any of the relays (l to C which have been actuated. When the relay C retracts its arn'iature, the energizing circuit of the ma netiG is interrupted, causing this magnet lo retract its armature, thus permitting the rod 75 to return to normal.

The subscriber now sends lhc ncxl scries of impulses corrcspomlingr to the units digit. which in the case assumed is 9. Tu response to each of these impulses a relay correspoluling lo the relay C" is energized and locked up, while a relay corresponding to relay 1 is dci uernizcd. At (h termination of the line iu'ipulses the relays C to (,l

and relay ll) will be actuated and locked up and the relays c to 0 will be deenergiaed. Wl'ien now the resistance M3 is shunted from the operating circuit of the relay 23, a circuit is completed. from ground, right-hand armature and front contact of the relay i 33, conductor ell, armature and front contact of relay lii, armature and back contact of relay 48, contacts 6% and 65, armature and back cont-act of the relay 69, contacts and 81, contacts 82 and 83, winding of the relay 8%, to grounded battery. Relay Sal attracts its iii-matures and establishes a loch:- ing circuit for itself by way of its righthand front contact and armature over the circuit just described. At the right-hand armature and contact of relay 8% a circuit is completed from grounded battery, armature of relay 8e and contact. 85, conductor '72, winding of magnet 15, conductor 87, lower front contact and armature of relay l0, armature and back contact of relay 60, to ground. Magnet 15 is energized in this circuit. Magnet 15 rotates the rod 75 in a clockwise direction to set the stop 88. T he armature of magnet 15 is operated and closes a circuit from ground, spring 89 and its contact, conductor 90, winding of magnet 86, contact 91, right-hand armature of relay Sl to grounded battery. The magnet 86 is energized and unlatches the arm 2 of register R permitting this arm to rotate until it engages the stop 88. The armature of the relay 86 in operating closes a circuit from grounded battery, contact and spring 92, conductor 59, winding of the relay 60, contact 61, contact spring. 62, through the winding of relays C to C, the righthand ti-onlcontacts and armatures of these relays, conductor 44, to grouind at the lefthand front contact and armature of relay l3. Relay 0 attracts its armature and at the contact spring 62 interrupts the holding circuits of the relays C to U" It will be understood that as many registers of the type of register R will be employed as there are digits in the desired number. For registering a number of more than three units, it will only be necessaryto increase the number of registers and lengthen rods 8 to 12 and provide them with the necessary stops for each register. In the description of this invention it has been deemed necessary only to describe the setting of the registers. In the employ ment of this invention in a telephone sys' tem after the registers have been set they may be used to govern the operation and setting of counting relays, which in turn control the setting of automatic switches in the manner clearly shown and described in the patent to A. E. Lundell, 1,168,819. V7 hen it is desired to erase the number registered the subscriber replaces the receiver on its switohhoolr. This causes the separation of the switchhoolr springs 52?. and 22 and, in turn, the deenergisation of the relay Relay on deenergizing at its front contact and armature interrupts a circuit which maintained the relay l3 energized. The relay -13 at its left-hand back contact and ari'nature closes a circuit from ground, conductor 94;, contact 95, winding of the motor magnet 96 to grounded battery, and in parallel through contact 97, winding of motor magnet 98 to grounded battery, and contact 99, winding of the motor magnet 100 to grounded battery. The motor magnets operate in the manner of the sequence switches to restore the registers R, R and R to their normal posilion, in which they will be held by book 6.
