To (17] wit/m2. it may concern.

Be it known that 1, CHARLES E. Barman, a resident of McKees Rocks, in the county of Allegheny and State of Pennsylvania, have invented a new and useful improvement in Railway Systems. of which the following a specification.

This invention relates to electric railway systems, and particularly to toy, display or carrier systems, in which all of the mechanism is operated by the propulsion current.

The object of the invention is to provide an automatic electric railway system-embodying a block signal system controlled or OPPIfltGfl by the propulsion current and arranged to prevent succeeding cars from running into each other.

A further object of the invention is to provide an electric railway system embodying' automatically controlled or operated track switches arranged to switch the trains into the sidings, said switchesbeing operated by the propulsion current, and closing to again connect up the main lineafter a car has entered a siding.

furthe object of the invention is to provide a system of the character described in which certain cars or trains can be switched into a siding to permit other following cars or train: to overtake and pass, at the siding, the car which has been switched thereinto.

A further object of tlie'invention is to provide a system in which under certain conditions a following train, such as a pas 'seuger train. will close a circuit or circuits. thereby causing a train ahead on the main line to automatically open and take a switch into a siding.

A further object of the invention is to provide a system in which the supply of current to a train standing on a siding. for propelling the same out upon the main line, is controllcddrv a following train on .the main supply circuit to the train on the siding in passing the siding on the main line.

further object of the invention is to provide anelectric railway system suitable for use as an automaticconveying; or carrying system. and in which the cars automatially move along the main line and can be brought to rest selectively at any one particular station or siding on the main line. and can then he returned when desired to the starting pointline. which closes the branch current Further objects of the invention are in part obvious and in part will appear hereinafter.

In the drawings Figure 1 represents dia grammatically a system embodying the invention; Fig. 2 is an enlarged detail view of a semaphore and circuit controlling member the parts being shownwith the sema' phore in the green position; Fig. 3 is a detail end view, partly in section, from the left in Fig, 2; Fig. 4 is'a similar view showing the semaphore in red position; Fig. 5 is a side elevation of a railway switch controlling member; Fig. 6 is a planview thereof; Fig. 7 is a side elevation of another circuit controlling member; Fig. 8 is an end view thereof; Fig. 9 is an enlarged plan view of a track switch, and mechanism for controlling or operating the same; Fig. 10 is a detail view. showing a difierent position of the electric switch illustrated in Fig. 9;-

ll and 12 are similar views of another electrical switch; and Fig. 13 is a diagrammatic view of the lighting circuits;

The systei'n shown in the drawings is of the third rail type. in which the'propulsion current is collected from a third rail divided into sections, transmitted through the car motor and returned by way of the track rails. As illustrated, the system is operated by a source of current A, such as a battery or generator, which isconnected toa feed conductor 3 extending along the full length of the track and sidings; and which supplies current to the several sections of the third rail C.

The car 'is represented diagrammatically at Dtlllt-l embodies one or more motors E of any suitable type and supplied with current from a collector or shoe F traveling along the third rail (t represents theticl-d winding. of the 1notor. through which the current transmitted to the frame of thecar l) and then to the return track rail or rails H.

At each block or section ofthe main line.

thnee being shown, is located a semaphore.

and circuit contrclling. member, having an arm controlled by two elcctromagncts,saidmagnets also controlling several circuits in.

the system and hereinafter referred to more in detail.

J rc ircseuts a railway track switch leade ing into a siding J. said track switch 'J b ing operated by a motor K.- The circuits to this motor are controlled by the duplex electromagnet L, shown in detail in Figs. 5 and 6. I

Third rail C is divided into a plurality of sections, marked respectively C C C C, etc., and referred to separately hereinafter. Eachof said sections. of the third rail is supplied with current by a circuit leading from the feed wire B.

Assuming that the car D, shown in Fig. 1 is traveling along the track from right to left, and that all blocks ahead of the car are clear, it will be propelled along section 0 and will then pass over the break onto Section C Semaphore I is at the green or safe position and current is consequently being supplied to section C ,'the semaphore and circuit controller being constructed and arranged as follows: As shown in Figs. 2, 3 and 4, it comprises a base 1 on which is mounted a post or pillar 2 supporting a semaphore arm 3 of the usual type. On the base are mounted two electromagnet coils 4 and 5. One end of said base carries a pair of mercury cup contacts 6. At the other end of said base are mounted two pairs of similar contacts, marked 7 and 8, respectively. Above the magnets 4 and 5 is mounted a horizontal pivoted switch arm 9 carryingbridges a, b and c insulated from said arm and having end contact points adapted to enter the mercury in the cups.

' The middle portion of arm 9 is hollowed to arm 9 and loosely pivoted to the semaof current to the section C or. channel-shape in cross section to carry-a rolling. ball or weight 10. Whenever either end of said arm is depressed by operation of one of the magnets 4 or 5 the ball 10 rolls to that end of the arm and holds it by gravity in its new position. Said arm 9 is connected to operate the semaphore arm 3 by means of a rigid arm 1L securely attached phore arm at its upper end.

- Section C of the third rail at each block is supplied with current by a circuit 12, the wire of which includes the coils of the magnet 5 of a first, second or any other previous block, being shown as connected to the coil of the second block. Section G which is next beyond C is supplied with current through a branch circuit including the coil of magnet ft of the immediate or nearest block. \Vhenever magnets 4 are operated they turn the semaphores to red T position, closing contacts 6 and breaking c011- tacts 7 and 8, thereby cutting off the supply of the immediate block and nreventing a following train from passing the same. VVhenev r magnets 5 are operated by a train passing the second block ahead the semaphores are turned to green position, thereby completing the feed circuit to section C and allowing a following train to advance. .Semaphore I being in the position shown in Fig. 2, bridge 0 completes circuit 12 and the car travels .at different-distances from the track. Conone coil of the electromagnet L, which conalong section C until tion i I At one side'of the track, along semtion G is located a contact 13, adapted to be contactcd by an adjustable contactmember 14 on the car or train I). A similar contact is located in advance of every siding, the contacts for the different sidings being located it reaches sectact 14 is located or adjusted upon the car at the proper distance to one side to strike the desired track contact 13 or the like, so as to switch the car into any desired siding. then the car contact'lei strikes the track contact 13 a circuitis completed through trols an electric switch M and the circuits through the track switch operating motor K. 7 Switch M and the parts controlled there by are arranged as follows: The switch comprises two pairs of oppositely disposed contacts 15 and 16, the oppositely disposed contacts being adapted to be connected by bridge arms 0! and e mounted to rotate together on a pillar or support 17, the bridge arms being insulated from each other. Arms d and e are operated by a lever 18, one end of which is pivotally connected to a nut 19 which travels along a screw 20 connected by suitable gearin'gto the armature shaft 21 of motor K. Lever 18 is slotted at 22 to fit and slide 'on a squared member 23 connected to the two bridge arms at and e. A link '24 connects lever 18 to the movable member J of track switchJ, a spring 25 being preferably inserted between link '21 and member J A conductor 26 is connect ed to one contact 15, while the other contact 15 is connected to a branch from the feed wire B. In the position of the switch shown in F i s. 1 and 9 arm d bridges the contacts 15 an connection is made throughthe switch from the feed wire 3 to the conductor 26. The track switch J is also in closed position.

The circuits to-the-motor K for o crating the track switch and electrical switc 1 M are controlled by the electromagnet L, shown in detail in Figs. 5 and (3 and arranged as follows: Two electromagnet coils 27 and 2S are mounted side by side on a base "2%), having four pairs of mercury cup contacts 30,

31, 32, 33 at one end and two mercury cup contacts 34, 35 at the other end. Over the magnets are mounted two pivoted arms 36 and 37. One end of-arm 36 carries two insulated bridges f and g, which respectively bridge the pairs of contacts v30, 31. The other end of said arm carries a single c0ntact member h. Arm 37 at one end carries two insulated bridges, 2' and j and at the .125 other end a single contact 70. Both arms swing on the same pivot 38 and are provided with adjustable 'weights 39, to normally raise all of the bridges f, g, i and j from contacts 30, 31, 32, 3

Vixen car contact 14 strikes contact 13 a contact 15, through'brid e d, conductor 26 to the point 40, throng one winding of magnet 28 .and then through wire 41 to contacts l3. l4 and to the negative or return track rail. Arm 37 is pulled down, and the bridges 1 and 3' connect up the contacts 32 and Z 3.- Consequently current also flows from the point 40. through a second winding 42 of magnet 28, thence across bridge j, to a contact. 30, through the field winding N of motor K, then to a contact 31, thence across to the other pair of contacts 32, through bridge z', thence to the other contact30, thence through the armature winding'O of motor K. and then to negative or to the. re.- turn track rails. Motor K therefore begins to ope ate, rotating the screw 20 and cansing the nut 19 to traveltherealong. This oscillates arm 18 and bridge arm (Z begins torotaf around pillar 17 asan axis. Link 24 also moves the movable s'witch member J toward open position. This motion continues until the track switch is fully opened,

at which time arm d moves out of contact with contact members 15, thus breaking the circuit to the motor K from contact 1..

Both circuits through the coils of magnets 28 are broken so that arm 37 drops and its contact I; enters mercury cup 3i. timc before the contacts 15 are broken arm 0 strikes contact 16, as shown in Fig. 10, and bridges the same. This leaves the switch in condition for later operation when the car strikes contact member 45, as hereinafter described, to close the track switch.

The section C of the third rail is sup-' plied with current through the cup contacts 34 and inwire 43, leading from the feed wire I). These contactsarc controlled by the arms 36 and 37 as follows: Referring to Figs. 1 and G, the current travels from the feed wire to contact 35, thence into arm 36, thence across the pivot rod 38 for the arms 36 and 37, thence through arm 37 to contact 34', and then to the section C*. If either one of the magnets 27. or 28 is energized one of the contactsB t or 35 is broken, thereby cult ingoif the feed to section C. This protectsthe carand prevents it from passing over the switch J at any time when the same is being thrown by motor K, Vhen magnet '28 is operated to'start the switch operating mctor the feed to section C is broken and the train comes to rest on said section of the track. vl t remains there until switch J is fully open. when the circuit 43 will again with track contact member 45, when ,the

trai in i'ullr tered the siding. This Some it was, namely, at

completes a track switch motor circuit as follows: From the feed wire 'Bthrough coil 5 of the next previous semaphore I, co'nsequently moving the' semaphore arm to green position and closing its feed circuit 12,-thcreby feeding section C and permitting a following tram to go ahead over the main line,thcn through conductor 46, and to one contact 16 of switch M. In'the open position of track switch J arm bridges contacts 16. The current consequently flows across bridge arm 0 thence to the point 47 and through a winding of magnet 27-,thence to contact 45 and to the re turn rail. Arm 36 is pulled down, bridging all thOCOIltiLCts 30 and 31. upon also flows from the point 47 through the other winding of the magnet 27, then across the bridge g, through thefield winding Nof. motor K, but in the opposite direction from before; then to a contact 30, through the bridge and through the armature winding 0 tot 1e return rail, and in the same direction as before. The'direction of rotation of the rotor of motor K is consc quently reversed and the movable switch member J is closed. Arms d and c of the switch M are returned to their former positions, consequently restorin the circuits to normal condition. Since t e train has en tered the siding it is clear that any following traincan proceed and so not only the first preceding, but also the second preceding block, should be moved to green iposition. The train on the siding cannot contact section C on the main line opposite the.- siding to do this. Consequently, a circuit 48. in shunt with the circuit 12 to the section C of-th'e main line, is provided to supply current for section \Vhcnever section C. gets current the second preceding. block goes to green, as though it had been operated by a train on the main line.

Section C is made quite-short so that there is only a momentary impulse throu h the magnets 5 of the preceding blocEs; thereby preventing a' following train from passing its block and then passing its section (whiclr pulls the preceding block to rcd), before the train on the siding leaves the-section C Tf this occurred the preceding block might not be pulled to red by the following train, as both magnets 4 and 5 thereof would be actuated together and theblock would remain where green caused by the. train on C Thetrain now moves intothe siding along section C and comes to rest on section C, which is supplied with current through a branch from the' teed conductor in which is a normally open switch 49. Switch 49 may be manually controlled. but preferably is operated automatically as hereinafter described.

When it is desired ,to start the car and semaphores are turned to the move it out from the siding J, the switch 4!) is closed, thereby supplying current from feed wire B to section C of the third rail. The car then moves forward to section C". This section of the third rail is supplied with switch controlling current through circuits, as follows: from feed wire 13 through bridge I) and contacts 7 of the second preceding semaphore I, thence by -way 'of conductor 50- and through bridge 6 of the next semaphore II, thence to feed wire 51 and through a winding of magnet 28, thence to terminal 52 of switch 53, then across bridge 79 to terminal 55, to section C then throughthe car motor to negative. The circuit includes the bridges b of two previous blocks, and consequently if either of the two previous red position, no controlling current will be supplied to section (1", thereby preventing a car on the siding from moving out upon the main line, unless the car ahead is at leastv two blocks in advance. The windings of magnet 28" are such that only sufficient current can pass through the circuit described to operate said magnet, but not enough to turn over the motor of the car. The car will not,therefore, advance, even if current flows through the circuit described.

Switch M is the same type of switch and is operated by the same type of means as switch M. It differs therefrom in the following respects. Arm J is provided with a lead wiru'ili connected to the feed Wire B.

v This'arm cooperates with two contacts and 15 but connects with only one of these contacts at a time. Arm 0 is provided with a lead wire connection 60 which includes the two contacts 31, 35 of the (111- plex' electromagnct L This arm cooperates with two contacts lfi", 16". but only connects with one thercof at a time. Contact 15 is connected to a wire 100 leading to arelay 4. contact 15* to a wire 64 running to ma net '27". contact l0" to a wire 61 running to cction and contact 16 to a wire .101 running to section 0 of the lnain line.

The operation of magnet 98 pulls down its armature arm and estal'ilishes a switch controlling motor circuit as follows: The switch being in the position shown in Figs. 1 and 11. current flows from the feed wire ,0 to arm (1 thence to contact 15, thence. through wire 100 ton special second winding 57 in the magnet 4 of the next preceding block. thence to wire 58 and through a second winding 59 of magnet 28*. then across bridge j to a contact thence through the field winding N then to contact 31, to a contact 32*, across bridge to a contact 30 and through the armature winding of the motor K to negative. Energization of magnet 4 of the prebroken, so that whenever the swi ceding block thereby closes it to 7 a red v PO sition, preventing a following train on the J 2 is moved to open position and the arms d and c are rotated upon their supporting pillar. Contact 15 is broken when the track switch is finally opened and some time before this arm 0 moves on to contact 16". The. following additional circuit is then established: from feed wire B through the ordinary winding of magnet l of the next preceding block, thence to its section C and by way of conductor 60 and contacts and 34, arm e to contact 16", and then through wire (31 to section C. The car motor copsequently receives propulsion' current and moves ahead to section C, which isalso supplied with current from wire 60. Section C also acts as a protecting block in that if the car chances to pass over section (I on the run, in WlllChcase the controlling current supply to section CWmay be suiiicient to affect the motor, this controlling current will, nevertheless, energize magnet 28 and break contac't 34", through which current is supplied to section C". The car must therefore come to rest on section and remain there until the track switch is fully opened and contact 34 is again made, as described. The car passes out through the switch onto the main line. Here a trip or contact 62 on the right hand side at the rear of the car or train strikes atack contact 63 and completes a reverse circuit through the motor K as follows: from the feed wire B through lead wire 56 to arm then to contact 15, through wire (ti-l to the point 65, then through one winding of the magnet 27 to contact 63 and thence to the return rail. Magnet 27 pulls down its armature and establishes the following additional circuit from the point through the other winding of magnet 97. thence across bridge 9 through the field winding N direction from before then to a contact 30 acrcss bridge f ,.and through the armaturewinding to negative. v Since the currenttraverses the field winding in the opposite direction the motor K is reversed and the switch J closes.

The current for section C, which lies just previous to switch J is supplied from conductor by way of contacts 35 and 34, switch arm a and ,conductor 101, essentially the same circuit as at the previous block. If either one of the magnets 27 or 28 is energized one of the contacts 34 0133 is in the reverse controlling circuit to section C the car on the siding to operate magnet 28 flows through the electromagnet 7 7 main line from running into a car which is emerging. or has emerged, from the 7 siding. At T is shown a device for automatlcally controlling the switch 49 to cause a car traveling along the main line to start a car i on the siding out upon the main line. and to also prevent a car on the siding from run? ning'out onto the main line until the main line is free to receive it. As illustrated in Figs. 7 and 8, this device comprises a base on which are mounted two electro-magnets 71 and 72. Pivotally mounted upon said base is an insulating arm 73 ca'rrying a bridge m and the bridge or switch blade 49 atitsopposite ends. Bridge'm cooperates with two mercury cup contacts 74 and 75 completing a circuit between tacts 52' and 55 before referred to. The switch blade 49controls two cup contacts 76 and 77 in the feed conductor between the main feed wire and section C. The wind ings of electromagnet 72 are in the circuit. 12-t'o the section C of the main line at the siding J. Consequently, whenever a car reaches said section current "2, pulls down one end of arm 73 and causes the switch 49 to'close its circuit, thereby starting a car from the siding. The other end of" the arm is raised, moving bridgem out of its contacts, and breaking the switch controlling circuit to the section C so that the car on the siding merely-advances to said.

section and stops there. It, moreover, cannot advance until the preceding car main line advances at least two blocks and pulls the two blocks preceding the switch J? to f green position; This is because the circuitfrom section C includes the bridges b of the two preceding blocks, and unless those blocks are at green position, no current will flow through magnet 28 and a circuit through motor K will not. be established' The windings of the electromagnet 71 are in a circuit 78 from the main feed wire B to the contact 63. Every car in the system is equipped with a contact 62 arranged to strike the ,contact 63. Therefore, the car on the'mam line will strike the contact 63 and close the circuit through magnet 71.v

This pulls down the arm 73 and closes the allowing andproceed in the usual way. Preferably, a manually operated switch blade 79 is pivoted at the contact 52 sothat that part of. the circuit through the bridge at can be cut out when this, protective feature is desired to be omitted.

At the extreme-left in Fig. 1 is representthe switch con-v third rail on the on the through magnet 28' 1 ed a magnet 28 of a special duplex electromagnet, .like the electromagnet L, for controlling the track switch leading to a siding,

i the several circuits to the third rail, the adjacent blocks. etc. This magnet 28" is in a circuit 80 to av contact 81 lying at a special location near the track, and adapted to be contacted by a contact 82 on the car frame.

'The circuit 80 also includes the bridges a of one, two, three or more .previous blocks, three being shown. These bridgesfclose the As above described the red position.

turns a block each train or car in passing and previous block-to green. Consequently, there will always be two red blocks behind every train. .111 some cases cars or trains will be run at different speeds, for example passenger, trains will run faster than freights. Assume that a slow running freight has passed blocks numbered II and III. Ithas automatically turned block I to green. Therefore, when its trip 82 strikes contact 81 nothing will 'hapthe third block back. If, however, after the freight passes block III and before it reaches contact 81, a fast passenger passes block I saidblock will be turned to red. has the effect of leaving hind the freight. The/circuit to contact 81 is consequently complete. When the freight trip 82 strikes contact 81, magnet 28 is, energized and sets in operation the several from the shoe or collect-or F, said circuit intl'lldlllg a contact 93 and the armature 94 of high resistance co l 92, in

a relay having a 91 to the car a shunt 95 from said circuit frame or to negative.

reaches a dead secilon of the third rail, such as section (9, magnet 92 is deenergized and spring 96 pulls the armature 94 over to c0nfact 97. This contact is in a circuit from a special shoe or collector 98, located far enoughback on thetrain or car to be beyond the break between "section C .and thenext preceding section C or the like. Consequently, the car lighting system 90 now recircuit whentthe several semaphores are aten, as the circuit to magnet 28 is broken at This three red blocks bemotor controlling circuits to open the switch while the engine or gets its current, through a shunt circuit 91 Whenever the shoe F to red and simultaneously turns the secof an ceives current from shoe 98. When C be comes a live section, current again flows through the coil 92, the armature 94 is pulled over and the lighting system gets its current as before. i 7

V The apparatus described can be used in a number of different ways. For example, it can be used as a conveyer system for store service or the like. Each siding, such as the siding J can represent a station in the store service system. Assuming the switch 49' to be manually operated, each station, such as station J will be provided with a button 85 annunciator system, the indicator boardof which will be at some remote point, which may be considered the starting point ofthe system. If a person at station J} dcsires to give an order he presses button 85, announcing to the operator at the starting point that an order is to be given. The operator then starts out upon the main line an electric motor car having its contact 14 adjusted or set at the proper point to correspond with thetrack contact 13 at the particular station calling. The car proceeds along its way until contact 13 is reached.

when the track switch J is thrown and the car enters the siding. It comes to rest on the dead section of track marked The desired order is t-henplaced upon or in the car and the switch 49 closed by hand. This supplies current to track section C and the car begins to move out toward the main line.

The switch 49 is held closed until the car passes onto section C The apparatus then described opens the track switch J'', the car moves out upon the-main line, and switch J is then closed. The car then proceeds along the main line in the same direction as before and completes to its original starting point. The order can be filled and the goods can then be placed upon the car. The car can then be sent out to make another trip in the same n'ianner to deliver goods to the station J. Any numbe!" of stations can be provided along the main line and cars can be automatically switched into the siding at any one of said stations by properly locating the contacts 13 and 14 upon the several cars and at the several sidings.

The invention can also be adapted for display uses for store windows or the like, or

for a toy system for amusement "or instruction, in which case it will take care of the movements of a large number of cars, stopping them at various sidings and automatically causing them to proceed on their way. It can also be adapted for moving boats electrically over an artificial pond or stream, in which case the several track members and circuits canbe submerged beneath the water, and the boats hitched up to the rails by submerged traveling shoes or collectors. The

the circuit returning track can also be curved around islands and the like. Also, if desired, for a combination boat and which case the boat circuits to control the opening and closing 0 bridge for the railway over the stream, suitable connections being made between the block" system of the railway and the boat circuits so the bridge will not be opened when a train on the railway is dangerously close. All such adaptations and modifications I consider to be fairly within the scope of the claims hereto appended.
