This invention relates to recording system and has 45 Claims.

a train describing and for an object to provide a system whichY automatically describes and records passing trains at intervals along the trackway. More particularly the invention includes a system in which vided on the train which i a mechanism is pros adjusted to describe the train as desired and a companion mechanism is provided in dispatchers stations or other locations on the trackway which ramps or contact rails on are connected with the trackway. When the train engages one of the trackway ramps its describing mechanism is initiated and a combination of signals is transmitted to the trackway devices which describe the train and make a perand the time it passed the trackway. Another to automatically deof spaced stations on progress of the train determined. Other objects of the invention will be understood from the following specification and part thereof, in which,

Fig. 3 is a diagram of the controlling circuits 30 for the recording apparatus;

In the present invention the transmitting apparatus comprises a stepping mechanism which is adjustable to transmit steps which signals usually This apparatus remains inactive by a number.

groups of signals in designate the train 0 but is initiated to make one cycle of operations as soon as a trackway device is encountered. During this cycle the signals produced by the device are transmitted one or more receiving relay and selectively through an electric conductor to stations.

The signals are received through a polarized operate a group of stepping wheels from an initial position according to the number of signals received of the signals a tape is 5() 'the and upon completion brought into contact with stepping wheels and with the time recording mechanism which registers the signals describing the train and the time that it passed location on the with the signals and by a specic track. By recording the time spacing the recording 55 stations at predetermined intervals on the trackway it is possible to keep an accurate record of the train over each portion of the track.

In the drawings, SIU is the frame, SII, SI2 and 6I3 are stepping magnets of the recording device; as shown in Fig. 2, when the magnet 6I3 is energized the armature 6M is raised and through the link SI5 and the guide SIS the wheel S23 is stepped around one tooth for each operation of the armature SI4. Magnet SII operates stepping wheel S2I and magnet SI2 operates stepping wheel S22 in the manner described according to the principle of a ratchet stepping device. Gear wheel 62S moves with the stepping wheel 623 and engages gear S29 of the wheel S33, carring the register numerals shown; each step of the magnet 6I3 moves a different character on 633 into the registering position. The stepping wheel 62|, through gears S24 and S21 similarly operates the registering wheel 63| and the stepping wheel S22, through gear S25 and gear 62S similarly moves the registering wheel S32. Thus magnet 6I I moves forward the registering wheel S3I, magnet SI2 moves forward the registering wheel S32 and magnet SI3 moves forward the registering wheel S33.

When magnet SI1 is energized it attracts the armature SI8 and lowers the platen 644 moving on the pivot S45. This platen carries a ribbon of paper between the rollers S41 and S48 so that when the platen is lowered the characters on the registering wheels 63|, 632 and S33 are registered on this tape as well as the time on the index S30 which is operated by the clock mechanism shown in Fig. 2 in dotted outline in schematic form. A gear S49 mounted on a ratchet on the shaft of roller S48 engages the xed rack bar S50 so that as the platen is lowered the gear S49 is rotated and a fresh portion of paper is exposed to the registering wheels, These wheels are suitably inked for registering purposes by means not shown on the drawings. The ratchet on wheel S49 prevents movement of the paper roll on the return of the platen when released by magnet SI1.

When the platen is lowered the plunger S43 mounted on shaft S48a of roller S48 is lowered and lowers the plunger S430. through the guide in the base plate to close the circuit controller S05 hereinafter referred to. This also brings the pin S42 below the crank 64I mounted on shaft S40 and normally held horizontal by the weight Slla. When the platen is returned to the raised position by spring SIS, plunger S43a is raised and the quadrant S39 on shaft S40 is moved to the right to engage the pad S31a on the lever S31. This 2 lever is pivoted at 638 and cable 636 connecting to the upper end of this lever is Wound on the drum 635 as the stepping Wheel 623 is rotated. When the quadrant 639 is deflected by raising the platen 644 it is apparent that the stepping wheel 623 is restored to the normal position. Each of the stepping wheels 62|, 622 and 623 is provided with a drum 635 and a restoring mechanism similar to that described.

The wheel 626 is ring 696 provided with an insulated which is engaged by the contact fingers 691, 698 and 699. In the normal position shown in Fig. 2, the contact fingers 691 and 698 are connected in circuit While contact linger 699 rests upon insulation. As soon as Wheel 623 makes the first step, the contact finger 691 is disconnected from 698 and contact lingers 69B and 699 are electrically connected by the ring 696 throughout the remainder of the movement of wheel 623. The purpose of these circuit controllers is hereinafter described in connection With the operating circuits.

The transmitting mechanism as illustrated in Fig. 4, comprises the stepping magnet 669, provided With an armature 66|, suitably connected by a lever to the stepping arm 662 Which engages the stepping wheel 663, mounted on the shaft 664. This wheel is provided with an insulated ring 665 which is engaged by the contact fingers 654 and 655. In the normal position shown, the inger 654 rests upon insulation, but upon the iirst step of Wheel 663 the contact fingers 654 and 655 are electrically connected throughout the remainder of the movement of the stepping wheel.

The battery 652 653 has a central connection to ground at 66| and connects by Wire 659 to one side of magnet 666 and from this magnet to Contact 656, ring 666 contact 655, Wire 656, armature 66! in the deenergized position and wire 658 to battery 652. A shunt circuit is provided around the contacts 656 and 655 by Wires 656 and 651 When the contacts 62Min and St-b are bridged by the trackway conductor 666. Thus the trackvvay device 696 initiates the operation of the transmitting device by energizing magnet 666 to produce the first step of Wheel 663 and thereafter this Wheel continuously rotates through the circuit etsablished by contacts 669 and 656 and interrupted by the movement of armature 66| until a complete cycle of operation is made.

A contacter 61d is provided on the vehicle to engage the trackWa-y conductor 665; this contactor is connected to the transmitting mechanism at 612 and to contact linger 61|. Mounted on shaft 666 are the code transmitting segments 666, 661 and 666. These segments are insulated from the shaft 64 and are non-rotating. The number of teeth in each of these segments that may be exposed to the spring contact 61| is adjustable by the quadrant 669, arranged to cover one or more of the teeth of 666 and the quadrant 616 arranged to cover one or more of the teeth on 661. It will be noted that segments 666 and 668 connect by Wire 658 to the positive side of the battery and segment 661 connects by wire 659 to the negative side of the battery.

The stepping Wheel 663 carries the contact member 61| over the exposed teeth in the segments 666, 661 and 668 and thereby establishes a circuit from the positive or negative side of the battery with the contact 612 through 61| and the supporting mechanism. Thus during the operation of the transmitter, positive impulses are transmitted to the line 668 through conductor 605 ci for each exposed tooth on the quadrant 666 and, as soon as the contact 61| engages the quadrant 669, a continuous positive impulse is transmitted. When contact 61| engages quadrant 661, negative impulses are transmitted to the line in accordance With the number of exposed teeth in this quadrant and when 610 is engaged a continuous negative impulse is transmitted; following this a positive impulse is transmitted from 668. The number of impulses transmitted by 666 and 661 may be used to describe the train according to a number which is adjustable as described and, if desired, additional stepping quadrants may be provided to increase the number of characters in the transmitted code.

The operation of the registering device Will be Fig. 3 in which the polarized relay 689 is connected to the line 698 and is grounded at 65| so that the armature 619 of this relay is deflected to the right or to the left in accordance with the polarity of the current from the transmitter. When in the position shown the code signal received on wire 608 is connected through armature 619 by Wire 68| with contact Enger 668 of stepping Wheel 62| for mechanism y and by wire 63S, contact fingers on :stepping disc 622 of mechanism a: to Wire 685 and stepping magnet 6| for the stepping Wheel 62| of instrumentar. This steps around stepping Wheel 62| in accordance with the number of impulses received of this polarity and places the index Wheel 63| in position to register a character in accordance with the first group of code signals received.

'When the polarity of the current in the line wire 698 is reversed, the armature 619 is reversed and a circuit is established through Wire contact ngers 693 and 699, wire 688, contact nger 691 and Wire 699 to stepping magnet 6 I2 for the stepping Wheel of 62?. of instrument This steps around the index Wheel 632 in accordance with the second group of code signals transmitted.

When the current in the line Wire 608 is again Y reversed the armature 619 connects through wire 69E, contact ring 696 of stepping Wheel 62| for instrument y, Wire 683, contact ring 696 of disc 622 for instrument :c and Wire 69| to stepping Wheel 613. Stepping magnets 6H, 6i? and 6|3 it will be noted are grounded on wire 65|.

This causes the index Wheel 633 to be stepped I around in accordance with the third set of code signals received.

When the impulses on the line 696 are again reversed a circuit is established through contact 6'59, Wire contact ring 696 of stepping Wheel 66|, wire 666 contact ring 696 of stepping wheel Wire 662 to magnet 6|1 and to ground on 65|. When magnet 6|1 is energized, 6|8 is lowered to close the contact at 695 which establishes a circuit from the line Wire 686 to magnet 6 'i thereby holding this magnet energized directly by the current on the line wire 668. This magnet is slow releasing so that once it is energized it will remain in the energized position during any momentary interruptions of the line circuit such as would occur in the steps of the transmitted signals. Thus when magnet 6|1, which is not polarized, is energized to register the code signal it will not register again for subsequent signals until another trackvvay station Continued steps of the circuit energizing magnet 6H merely results in holding this magnet energized. Once the armature of this magnet has been moved to the energized position, the line rcuit is directly connected to this magnet through 685 and independent of the mechanism.

Magnet 6|1 is slow releasing to the extent of the time interval between steps of the same character, but the time interval between each group of steps is much greater than the interval between the steps themselves. This will be understood by the operation of motor 660 and the positions of the toothed quadrants 666 and 661. In consequence, magnet 6|1 releases its armature between the groups of steps but not between the steps themselves. Thus, if impulses are received from. the line after magnet 6|1 is energized, without changing the polarized relay 680, magnet 6|1 will remain energized and no further action takes place. If impulses are received from the line which changes the polarized relay, such as would result from a second operation of the transmitter, or from another transmitter, the interval between the change in the impulses of the new group from the old impulses, permits magnet 6|1 to deenergize, thereby restoring the apparatus to normal position for a new operation. Magnet 6|1 controls itself through circuit controller 695 and when the circuit through 695 is deenergized and magnet 6|1 releases its armature, the apparatus is restored to the starting position through 639 and 631. If magnet 6|1 is constructed with a time interval greater than the interval between the steps and the interval between the groups of steps, it will simply remain energized by the imline 608, through contact 695. It should be noted that the transmitter, Fig. 4, makes only one revolution, or cycle of operation each time it is initiated.

The apparatus described shows how code signals of three characters or groups may be received and registered on the instrument In addition to this the diagram shows how the system may be applied to selectively operate two registering instruments, the other instrument being indicated'by y and which will now be described.

1f the first impulse received on the line 608 reverses the position of the polarized relay 680 from that shown then a circuit will be estabto 682, contact fingers 691 and 688, wire 684, contacts on ring 686 of stepping wheel 622 for instrument y and wire 686 to stepping magnet 6|| which is grounded on wire 65|. This causes the index wheel 63| of instrument y to register the first signals of the code. When the polarity of the current on the line wire is reversed a circuit is established through 618, wire 68|, ring 696 of stepping wheel 62| for instrument 'y and Wire 681 of stepping magnet 6|2 which is grounded on wire 65|. This causes the index wheel 632 to step around in accordance with the second code signal from the transmitter. If the line impulses are again reversed in polarity a circuit is established from 618 through wire 682, stepping wheel 62|, wire 684, stepping wheel 622 of instrument y and wire 688 to the registering magnet 6|1 for instrument y. 'I'his magnet is slow releasing and when energized closes a circuit at 685 which directly connects the magnet to the line wire 608 and maintains it in thc energized position as long as the line wire 608 is energized. This magnet is similar to the corresponding magnet on instrument I. It will be noted that by controlling the stepping magnets by the stepping wheels to be subsequently operated, a selective control is obtained for these magnets; also by controlling the stepping magnets of one instrument by the other instrument a selective control is obtained which insures that only one registering instrument can operate at a time.

The transmitting device in Fig. 4 may be applied to operate the registering device in Fig. 3 as follows: The exposed teeth on quadrant 666 are arranged to transmit six impulses which will step around the stepping wheel 62| of instrument y thereby bringing the numeral 6 on the index 63|, under the platen 644. The polarity of the current is then reversed as the six impulses produced by quadrant 661 are transmitted to the line to operate the stepping wheel 622 and bring the numeral 6 of the index 632 under the platen 644. The next impulse produced by 668 energizes magnet 6|1 and registers the signals thus transmitted as the transmitting mechanism completes its cycle of operation.

This system may be applied to a railroad track as indicated in Fig. in which 60|, 602 and 603 are dispatcher stations and 605 are trackway stations for receiving the impulses from the passing vehicle. A line wire 608 connects each of the trackway contacts 605 with a dispatcher station and preferably with two dispatcher stations in multiple as indicated on the drawings. a train entering the track from the left will be simultaneously described in dispatcher stations 611| and 602 and this train will later be described at the next trackway station in the dispatcher stations 602 and 603. I the average running time between the trackway devices is known it is apparent that when a train registers at the first station it should register again within a predetermined time interval at the next station. Where a switch is in the track as at 2| it is apparent that a train which registers in 602 at the rst trackway instrument and does not register at the second trackway instrument has been switched at 2| to another track.

Trains operating on track 252, Fig. 5 are supposed to be spaced by a block system of the usual type, not shown in the drawings. By properly arranging the conductors 605 relative to the block spacing of trains, it is possible to prevent twc trains being in position to engage conductors 605 connected to the same line wire, at the same time, thereby avoiding confusion in the operation of the system.

This system relates to train describers in general and may be used in regular railroad service,

or may be used with an automatic system as disclosed in U. S. Patent 1,381,317, June 14, 1921.

The conductor 638 may be connected to one contactor 605, or a plurality, and this operation may be embodied in the block system as disclosed in U. S. Patent 1,857,760, May 10, 1932, which discloses the general features of the present application.

In the operation of this system, the transmitter, Fig. 4 may be located on the trackway and initiated by the passing train and arranged to operate a remotely located recorder. The invention as described admits of a variety of applications of which the drawings only illustrate one form. It may be applied complete as shown, or applied in part only, or in combination with other systems.

The recording mechanism, as shown in the drawings, is a developed mechanism for making a, permanent record automatically of the conditions on the trackway caused by train movements.
