as Claims. (Cl. 178-42) This invention relates to signal receiving methods and apparatus for recording intermittent code signal impulses and more particularly to means for recording such impulses in the form of dashes or dots and spaces on moving tape, though it is noted that in some of the claims the invention is not limited to impulse signals nor in some respects even to recording means.

One object of the invention is to provide an apparatus or device of this kind in which the intermittent code signal current impulses effect constant feed of the tape.

Other objects of the invention are to provide an apparatus of this kind for either perforated or inked records on the tape. I

In' apparatus in which the current signals, transmitted in the conductor in form of dots or dashes and spaces, are punched in the movable paper tape, it was heretofore the practice to have the first incoming signal impulse start the motor for feeding the tape and on the same initial impulse perforate the tape. It was intended that between the first and the second signal perforations, the tape should accelerate from 0 to normal speed and remain constant as long asthe signal was coming in. However, it was the custom heretofore to perforate the paper on the forward stroke of the electro-magnet; and it was clearly noticed, that on account of the time necessary for this necessary acceleration, the space between the first and the second perforations was smaller than the space between the subsequent spaces.

One object of the present invention is to cure this defect. This is accomplished by perforating the tape on the back stroke of the punch operating electromagnet and thus gain enough time for the tape to accelerate to the normal speed before the first perforation occurred. In order to perforate the paper on the back stroke, the novel type of electromagnet shown herein was devised.

Another object of this invention is to provide an apparatus in which all controls of signal perforating means, the tape feed, time stamp, ink ribbon motion and other functions of the apparatus, are accomplished by electrical means instead of the usual constructions, spring clocks. and mechanical gears, clutches and timing devices.

Another object-of the invention is to provide compactness in the arrangement of the perforator operating means, permitting the perforation of a plurality of signals on a single narrow tape, thereby adapting the single narrow tape and associated machinery to a large number of signal channels.

Another object of the invention is to provide a method of easily distinguishing the several closely adjacent rows of signal pe'. forations, when reading the signals.

Another object is to provide the combination with the signal registering devices, of a wellknown electrical pulsating motor, instead of a usual type of electrical motor, thus rendering unnecessary the heretofore used reduction gear system and effecting a quick acceleration of the tape.

Other objects'of the invention are to improve generally the simplicity and efficiency of such methods and apparatus and to provide a device or apparatus of this kind which is economical, durable and reliable in operation, and economical to manufacture.

Still other objects of the invention will appear as the description proceeds; and while herein details of the invention are described in the specification'and some of the claims, the invention is not limited to these, since many and various changes may be made without departing from the scopeof the invention as claimed in the broader claims.

The inventive features for the accomplishment of these and other objects are shown herein in connection with two'improved registers oneof which, briefly stated, includes registers receiving signals from a plurality of code signal devices for sending intermittent current impulses. In one form of the register the impulses are recorded by the register by punching the code signals in tape fed by a motor driven feed means.

Means are provided for connecting said devices to the punch means and a slow-release timed relay, whereby the timed relay is energized dur-' ing and between the signal impulses and acts to constantly connect the feed motor to a current source during the intermittent operation of said device, whereby the tape is constantly fed only during signal sending.

In the other form of .the register, the impulses are recorded on the tape by a plurality of marking devices such as fountain pens or pencils.

While in this specification and claims mention is made of the pens, pencils, punches and tape, it is understood that these wordsare used for designation and description and that for purposes of protection they are to be construed broadly enough to cover other recording means and devices, in general the terms herein are to be given for the purposes of protection broad interpretation when possible.

The multiple punching register The principal features of the punching register will first be briefly indicated, after which they will be described in detail.

A plurality of line relays 130, 131, 132 (Fig. 4) or other code-signal devices are each adapted to send intermittent code-signal impulses by way of conductors 138, to punch operating magnets (Figs. 4 and 5) corresponding with said signal devices for operating hammers (Figs. 2, 5, '7) for driving punches 75 for punching the code signals in tape 35 (Fig. 1) fed by tape feed means 38, 41 operated by 'a feed-motor 55, 57 (Fig. 3) operated as will be explained.

Conductors 138, 139, 140, 141 (Fig. 4) connect said magnets 80 in series between the respective devices 130, 131, 132 and a main relay 145, 150, 151, whereby the relay switch 150, 152 is intermittently actuated during signal sending.

A slow-release timed relay 154, 155, 158 is actuated by said main relay for constantly connecting the motor 55, 57 through conductors 151, to the current source 144 during, between and after the intermittent operations of the main relay, whereby the motor operates to feed tape continuously during and a few seconds after the intermittent signal impulses.

A time clock 115, has a magnet operated means 121, 123 (Fig. 1), for stamping the time on the tape, set in operation by a slow release stamp operating relay 167, 168 controlled by the timed relay switch 154, 158 for slowly intermittently connecting the current source 144 to a stamp operating magnet 121 in the time clock 115.

Now the various features of the punching register will be described in detail.

The register housing The various parts of the code-impulse-operated constant-tape-feed register are shown herein as mounted on sheet metal, housing parts including a frame comprising a base 10 (Fig. 1),-

an upright inner longitudinal main partition 11 and an end cross partition 12 mounted on the base, and a top wall 14 mounted on the partitions and having a long longitudinal window 15 (Fig. 9) therein.

Said frame is adapted to carry side and end housing-walls (not shown), the partitions cooperating therewith to form tape supply and control longitudinal compartments 16 (Fig. 1) and 17 (Fig. 3) and an end compartment 18 (Fig. 1) for receiving the various apparatus parts.

The paper feed A rotary supply reel shaft 20 and a take-up reel shaft 21 mounted on the main partition 11 in the supply compartment carry supply and take up reels 24, 25 respectively, the supply reel 24 being nearest the end partition 12 and comprising a hub 2'7, a disk 28 fast thereon, and an annular series of round-ended pins 29 on which the supply roll 30 of tape may be frictionally forced, slightly deforming the round shape of the roll opening. Small guide rollers 32, 33, 34 mounted at corners of the main partition guide tape 35, 36 from the supply roll upwardly along the end wall 12, under the full length of said window 15 to the rear upper corner of the supply compartment, whence the tape is guided to the take up reel 25, as will be explained.

The take up reel comprises a cylindrical block mounted fast on the shaft 22 having a small cylindrical peripheral cut-out 37 having a slit communicating with the reel periphery, into which slit and cut out the end of the tape is threaded in order that the tape may be frictionally wound around the reel.

A motor-driven rotary feed-shaft-38 mounted in the main partition between the take-up reel and the adjacent guide roller 34 carries a knurled or toothed feed wheel 39 engaged with the tape.

A pivoted frame 40 pivotally mounted on the partition carries a pressure roller 41 held engaged with the opposite face of the tape by a spring 42 strained between said frame and a screw on the partition, for causing the pressure roller to press the tape into driving relation with the tape.

A supporting block 45 mounted on the partition 11 about midway between the reels carries a threaded projecting pin 46 carrying a retaining bar 47 perforated to receive said shafts 20, 21 and pin 46 removably held in place by a wing nut 48 on the pin holding the bar and consequently the rolls and reels in place.

Drag levers 50, 51 are pivotally mounted on the partition 11, one lever 51 frictionally engaging the feed roll, the other carrying a flanged guide roller 52 engaging the take up roll to guide the tape to the latter and to prevent the rolls from unwinding.

The paper-feed motor The tape is fed to the punching means by a pulsating or stepping feed motor mounted on the main partition in the control chamber and secting said offset portion 70, the magnets being comprising a pulsating magnet 55 (Figs. 3 and 4) and a bell crank lever 56, 57 pivoted at its angle part 58' near said magnet and comprising an arm 56 forming an armature attracted by the magnet and an active arm 57 longitudinal to the magnet and lowered when the armature is attracted by the magnet.

A spring 58 raises the arm when the magnet is deenergized, thereby causing a pawl 59 on said arm to rotate a ratchet wheel 60 on the feed shaft 38 thereby to drive the feed shaft and tape a very small increment each time the magnet becomes .deenergized. When the magnet is energized the insulated projection 61 opens the switch 62, 63, breaking the current through the magnet 55, causing the motor to pulsate. A detent-pawl-spring65 mounted above the motor engages the ratchet wheel to prevent retrograde rotation thereof.

Pulleys 66, 6'7 in the control chamber 17, car-, ried on said feed and take-up shafts 38 and 21 respectively, carry a belt 68 yieldably connecting the pulleys to yieldably rotate the take-up reel 25 as the feed rollers feed tape thereto.

The punches The end or cross-partition 12 is constructed with an off-set portion 70 (Figs. 1 and 2) adjacent to the up-course '36 of the tape to form an inner recess 71 receiving a punch box 72 disposed in said recess and secured to an extension 73 of the main partition 11, and carrying a horizontal row of yieldably retracted punches 75 perpendicular to, and adapted to engage, the tape and passing through said off-set wall portion 70. A die 76 mounted on the main partition backs the tape and has apertures alined with and receiving the punches, the punched out pieces of tape dropping into a magazine 7'7.

The back stroke magnet perforator The magnets 80, 81, 82, 83 (Fig. 2) for driving the punches are mounted in frames 85 mounted on brackets 86 (Fig. 1) mounted on the outer face of the end partition 12. The magnet frames 85, and the magnets therein are mounted on said brackets respectively, in vertical and horizontal planes perpendicular to the partition and interaxially inclined toward said portionand .away from the partition 12. I

Punch-actuating members 88, 89, 90 (Fig. 5) are pivotally mounted on said frames 85, and each comprises a U-shaped portion 88 having its yoke portion formed with or carrying an armature 91 adjacent to the outer end of the magnet and its arms pivoted as'by the pin 92' to-said frame 85, one arm 89 of each member being extended beyond the opposite end of the magnet and disposed vertically across the outer end of one of the respective punches 75. The pivotal axis of the pin 92 is so arranged that when the armature 91 is attracted, the arm 89 is retracted a distance fromthe punch in the plane of the punch.

Massive heads 90, 90a, 90b, 900 are secured on the ends of the arms 89, 89a, 89b, 89c respectively, the heads respectively compressingslender portions 95, 94a, 94b, 940 secured to the adjacent end of the arm, and one or'more mass portions disposed a distance from the punch to avoid crowding. A tension spring 95 (Fig. 5) is secured between an eye 96 oneach arm and a pin Won the frame, the spring being approximately parallel with the arm when the arm is not retracted from the punch, and about 45 degrees to the arm when the arm is retracted and the spring is under tension.

The special construction of the perforator mag- 'nets and hammers show many advantages.

All of the electromagnets are located radially with respect to the associated punches, as it is shown in Fig. 7. While there are only four magnets shown, the same arrangement can be usedwith a. greater number of electromagnets.

The thin portion 94, of each hammer which delivers the blow to individual punch pins '75, are closely spaced and perm-it the punches to be spaced closely.

The masses 90 which furnish most of the necessary mass of hammer are placed on extensionsof thin portions 94, so as not to obstruct the movement of the individual hammers.

The mass 90 is connected to the thin portion of hammer in such a manner that the center of gyration of hammer and magnet arm passes substantially through the axis of corresponding perforation punch 75.

' Operation of the punches Thus it is seen that said magnet, arm, mass and spring are so related that when the air gap is greatest, the magnetic pull on energization is much greater than the pull of the spring, the pull of the spring increasing slightly faster than the magnetic pull as the air gap decreases and exceeds the magnetic pull as the gap reaches During the travel C where magnet pull is greater than spring tension the resultant force will'accelerate mass 90.

During the following travel D, spring tension is greater than the magnet pull and the mass 90 will decelerate until energy stored in it is zero.

-At this time the tension of spring 95, which in this case is considerably greater than the magnet pull, will bring mass 90 back "and strike the punch 75.

For a person skilled in the art, it is possible t select the spring tension curve, and value of mass 90 and also design the magnet forany particular speed of incoming signals. This spring system is a great deal more eflicient than the onespreviously used.

The signal distinguishing table 100, adjacent stripes contrasting, to facilitate distinguishing one signal from another.

The time clock A time and calendar clock mounted on the cross-partition above the hammers 90 (Figs. 1 and 2) is of usual construction and not shown in detail. As will be explained, it comprises a magnet 116 (Fig. 4) adapted to set the time stamps and receiving minute impulses. The clock is also provided with a ribbon feed magnet 120 and a stamp actuating magnet 122 adapted in the usual manner to actuate a platen lever 123 (Fig. 1) passing through an opening 124 in the main partition 16 and having a platen 125 on its end engaging behind the tape 35 to strike the tape against time stamps.

The electrical connections for actuating the variousparts above described will now be described in detail.

The signal sending means The signal impulses may be supplied in any suitable manner and are here shown as being received from a plurality of line relays each comprising a line magnet (Fig. 4) adapted to receive code signal impulses from signal lines or loops not shown, and a switch 131, 132 intermittently closed by said magnet when intermittently energized by code signal impulses.

The signal punch actuating magnets and main relay Conductors 135 to 141 connect said punch actuating magnets 80 and the respective signal switches 131, 132 in series between the ungrounded terminals of the current source 144 and main relay magnet 145, said main source and relay magnet having grounded terminals 146 and 147, to complete the circuit, whereby whenever one or more relays 131, 132 are actuated, respective punch magnets 80 and the main relay magnet are energized. A condenser 148 is connected between '2. ground and each conductor 139 at a point between the actuating magnet and the relay switch 131, 132 to prevent sparking at the latter switch.

The armature 150 of the main relay is connected by a conductor 151 with the main current source 144, and is adapted to engage a switch contact 152.

The timed relay A slow release timed relay comprises an armature 154 connected to said main source 144, and a magnet 155 having one terminal grounded and the other connected to said main relay switch contact 152 whereby whenever the main relay is operated the timed magnet 145 is energized and charges a condenser 156 interposed between the magnet terminals, which discharges on deenergization of the magnet 145, and holds the magnet 155 energized a few seconds; whereby when the main relay switch is momentarily closed by code signal impulses the timed relay magnet is energized from the contact 152 and said condenser is charged, the condenser being of a capacity large enough to hold the magnet charged several seconds after the impulse has ceased, thereby to hold the timed relay c0ntact158 engaged continuously during a multiple-impulse code signal and several seconds after the last impulse, thereby to furnish current to the impulse motor through a service conductor 160 connecting the timed relay switch contact 158 with one terminal of the motor magnet 55.

The switch 62, 63 is connected between the other terminal of the motor magnet and a ground and is opened by action of said member 61 when the armature is attracted, for pulsating the motor. A resistance 162 and condenser 163 are connected around said switch 62, 63 to reduce sparking at the switch. It is thus seen that said motor pulsates continuously so long as the timed switch 154, 158 is closed.

The time stamp relay A slow action pulsating time stamp relay for energizing the time stamp magnets 120, 121 comprises a contact 165 connected through a resistance 166 to said service conductor 160, an armature 167 normally engaging said contact 165 and'a magnet 168 connected between the armature 167 and a ground. A large condenser 170 is connected around the magnet 168, whereby the condenser 170 is charged and the magnet 168 is energized whenever the timed switch 154, 158 is closed, the magnet being held energized by the discharge of the condenser 170, and the armature after being attracted is slowly released and. consequently slowly pulsated as long as the switch 154,

158 is closed.

A contact plate mounted on said armature and insulated therefrom is connected by a con ductor 176 to the time stamp magnet 121 and a ribbon feed magnet of the calendar clock 115 (Fig. 1), said magnets being connected between said contact plate and a ground 178. A contact 180 connected to said service conductor 160 and engageable by the plate 175 causes the stamp and feed magnets 121, 120 to be energized when said contact 180 is engaged and the timed relay switches 157, 158 are closed at the same time, thereby at intervals actuating the time stamp lever 123 (Fig. 1) to print the time indicia 106 (Fig. 8).

A condenser 182 and resistance 183 in series between the service conductor 160 and a ground is provided to eliminate sparking of switch contacts connected to such conductor.

Operation of the punch register As the signals come in from a signal box, one of the switches is intermittently closed, and a circuit is established from the, current source 144, through conductors 136, 137, 138, the corresponding punch magnet 80, conductors 140, 141, main relay-magnet, to ground 147, thus operating the I corresponding punch 75. This circuit remains complete for each instant during which the switch 131, 132 is closed.

Operation of the timed relay Operation of the pulsating motor The delayed closure of the switch 154, 158 holds the motor magnet 55 continuously conhected through conductor 160, switch 154, 158

and conductor 151 with the source 144.

This causes the motor magnet to pulsate the armature 56 and rotate the ratchet 60 to feed the paper tape.-

Operation of the time stamp relay Closure of the switch 154, 158 also supplies current to the self energizing time stamp relay 167, 168. Action of this self-energizing time relay isalso similar to that of an electric bell. Current passes from the service conductor 160 through the switch 165, 167 of this relay, charges condenser 170 (which may have a capacity of 3000 mf.) and attracts the armature 167 and opens its switch 165, 167. The magnet 168 stays energized for several seconds until condenser 170 discharges to the point of releasing the armature 167. This release closes the switch 165, 167 and the condenser charges again. This process repeats itself as long as the time delay relay 154, 155 is energized.

When the armature 167 is released of contact between the plate 175 and contact 180 supplies current through the conductor 176 to the stamp magnet 121 and ink ribbon magnet 122 and operates them periodically.

The calendar magnet 116 for time setting the time stamps is operated from the minute contacts 184, 185 closed by a cam 186 of a time clock located in central oflice, current being supplied from the source 144, through conductors 135, 187, 188 to a ground.

The multiple pen register This apparatus relates to a signal recording instrument, by means of which current signals,

ing signal sending,

partments 212 and 21 3.

transmitted in the conductor, in forms of dots, dashes and spaces, are recorded by a fountain pen on the movable paper tape.

The principal features of this form of the invention are briefly indicated as follows:

The code signal device 131, 132 (Fig. 13) for sending intermittent current impulses, the tape feed means 224, 226 (Fig. 11) and the motor 55, 57 (Fig. 12) therefor are similar to those shown in Figs. 1 to 10. But the recording means includes fountain pens or pencils 250 (Fig. 11) and magnet-operated means 235, 253, 255 for applying the pencil to'the tape 218 for recording the code signals on the' tape.

There is also a slow release timed relay 154, 155, 158 (Fig. 13) and means'141, 145,150, 151, 152 operatively connecting said signal devices 131, 132 to said magnet operated means 235jand relay, whereby the timed relayis operateddur- The housing The various parts of the multiple penregister are mounted onsheet metalhousing parts lor frame comprising a base 210, anupright inner end housing-walls form a tape supply and control apparatus comeke-paper feed "Awriting table'or shelf 215 (Figs/11 and '17) and a rotary supply reel shaft'216 are mounted along said frame.

on the main partition21l in the supply compartment 212, near the respective end portions of the compartment. 'A supply reel 217 on said shaft carries a roll of tape 218 guided by' small guide rollers 220, 221 mounted onthe main partition in position to guide tape from the supply roll on to the table 215, whence the tape is guided frontwardly of the housing.

A rotary feed shaft 223, mounted in the main partition between the end of the housing and the adjacent guide roller 221 at the discharge end of the table carries a knurled or toothed feed wheel 224 engaging under the tape. I

A pivoted frame 225 pivotally mounted on the partition over the tape, carries a pressure roller 226 engaged with the top face of thetape under the action of a spring 227 strained between said frame and a pin on the partition, for causing the pressure roller to press the tape into driving relation with the feed wheel.

Said supply shaft 216 carries a threaded projecting pin receiving a retaining bar 230 and held in place by a nut 231 for holding the supply roll and reel in place. A drag lever 232 pivotally mounted on the partition, frictionally engages the supply' roll, to exert a drag on the tape.

The pen support Lower and upper horizontal bars 245, 246 (Figs.

11 and 17) in the control compartment are mounted on the partition 211 above the table 215 near said short arms 241. The iippe'rbar v has an outwardly disposed horizontal shelf por tion 247 provided with a series of guide openings The openings are 249 extending above the tape. progressively further from the partition 211 and receive fountain pencils or pens 250 disposed in said openings and adapted. at times to rest their marking points on the tape to make short signal code dashes 251 thereon in parallel paths corresponding to the pens and signal sending devices.

Vertical pen supports each comprisesa lower body portion 253 guided between adjacent screws 254 passing, through the lower bar 245 and held against the lower bar by the screw heads. Each body portion is formed with an outwardly disposed perforated portion 255 (Fig. 17) adapted to receive the lower end of the pen, and with an upper shank portion '256 secured to one of said short arms 241 respectively whereby the pencil support is normally held raised by the spring 242, and intermittently lowered when the magnet is energized by code signal impulses.

The arms 256 are progressively. longer as they approach the adjacent end of the partition, to correspond with the stepped arrangement of the magnets 235.

A spring 257 mounted on each pen holder, presses upon the pen body and holds the pen against movement from side to side.

A flat spring 258 (Fig. 11) mounted on a bracket 259 on the partition presses the tape fiat against the table; and acurved plate 259 mounted under the tape guides the tape to the discharge end of the housing, when it may be discharged through a suitable opening into a basket or elsewhere.

The electrical connections As in the punching register, the multiple .pen register receives signal impulses from a plurality of line relays each comprising a switch 131, 132 (Fig. 13) adapted to give code signal impulses from signal impulses; and conductors 135 to 141 connect said pen actuating magnets 235 and the respective switches 231, 232 in series between the ungrounded terminal of the current source 144 and the main relay magnet 145, whereby whenever one or more relay 131, 132 are actuated,

respective actuating magnets 235 and the main relay magnet 145 are energized, connecting the switch contact 152 through the main relay armature and conductor 151 to the source 144, thereby to operate the slow release timed relay 151, 155 to connect the contact 158 through the armature 154 and conductor 151 to the main source, whereby when the main relay switch is momentarily closed by code signal impulses, the timed relay magnet is energized and the condenser 156 is charged, to hold the magnet energized between and after the impulses, thereby to hold the timed relay contact 158 engaged during a multiple-impulse code signal and connect the motor 55, 57, through the service conductor 160 to the main current source 144, said motor pulsating continuously and feeding the tape so long as the timed switch is closed.

The electrical connections of Fig. 13 are pro The operation of the multiple pen register The operation of the signal sending devices 131, 132, the main relay 145, 150, the timed relay 154, 155 and the paper feed motor and means will be readily understood from the operation of the multiple punch register.

The energizing of the pen operating magnets 235 is also similar to that of the punch magnets 80; but the pens 250 are lowered and caused to record on the initial stroke of the armature 239 rather than on the backstroke.

When one or more of the switches 131, 132 are intermittently closed during signal sending, the corresponding magnet or magnets 135 are energized, thus lowering the corresponding pen or pens to the tape as the latter is fed across the table 215 and discharged from the end of the machine.
