BRUNO OTI O WAGNER, OF EL PASO, TEXAS. COMBINED SYSTEM OF ELECTRIC SIGNALING AND SWITCH-SETTING FOR RAILROADS.

To all whom it may concern:

Be it known that I, BRUNO OTTO WAGNER, at present residing in the city of El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Systems of Electrical Signaling and Switch- Setting for Railroads, of which the following is a specification.

My invention relates to certain new and useful improvements in electric signaling and switch-setting systems for railroads and inits generic nature my invention seeks to provide a system of this character of a simple and positively-operating kind in which means are provided for opening and closing rail-switches, which means are always under the control of the operator, and means for informing said operator automatically by a visible si nal at his station when the switch has reac ed its required position.

The complete system also includes means for operating a semaphore-blade or dwarf signa so as to inform the engineer of an approaching train in a visible manner, of the position of the switch and at the same time return the signal to the station to inform the o erator that the respective track-signal is 0 car.

My complete system also includes the use of electric lights in place of oil-lanterns for track signaling during the night and means for instantaneously and automatically reporting to the operators station when the light has been extinguished.

Again, the system includes means for heating the rail-switches electrically in Winter to prevent them from becoming inoperative and clogged by snow and ice and means for allowing t e operator or inspector to have a supervisory insight into the Working conditions of" the entire system at any time to keep him posted on eventual interruptions of the circuits, inform him of short circuits, leakages, and defects in the apparatus, &c.,in order that the faults may be quickly discovered and remedied.

Patented April 17, 1906.

ratus is in direct electrical connection with the rail-switch-shifting apparatus, so that both work together, keys or circuit-closers combined with said track, and signaling apparatus to operate visible signals at the station to correspond with the home signals before mentioned; third, an electric signal-lamp for night service forming a part of the sema phore (track-si nail) and being covered by a transparent co ored disk when. the semaphore-blade is in its danger position, a suitable compensating resistance being provided to take the place of said lamp during the daytime and arranged to be cut out of circuit while the lamp is burning; fourth, an electric lamp held in a lantern near the track-signal, which v is so arranged that it will be lighted up during the time the main. signals are being changed; fifth, electric heating-boxes con nected in the field-circuit of the rail'switch and track apparatus and located under those partsof the rail-switch which are to be protected against snow, frost, and ice; sixth, in dicating devices for indicating signals in the station and other indicating devices arranged in combination with a measuring instrument for testing the system as to its working conditions and its efficiency.

In its more detailed nature my invention includes certain novel combinations of parts forming a complete electric si naling and switch-setting system, all of which will be first described in detail and then specifically pointed out in the appended claims, reference bein had to the accompanying drawings,in whic a Figure 1 is a plan of the switch portion of the railroad-tracks and its immediate coop- -eratin parts. Fig. 2 is a part section and part c evation taken on the line 1 1 of Fig. 1. Fig. 3 is a diagrammatic view of my complete system. Fig. 4 is a detail longitudinal section of the rail-switch-setting apparatus, the

parts 47 and 47* being omitted. Fig. 5 is a section taken on the line Y Y of Fig. 4, taken in the direction of the arrow. Fig. 6 is a de tail view hereinafter specifically referred to. Fig. 7 is a cross-section taken on the line X X of Fig. 6, taken in the direction of the arrow. Fig. 8 is a detail view of the testing instrument shown in Fig. 3. Fig. 9 is a cross-section on the line W W of Fig. 8 and taken in the direction of the arrow.

Referring now to the accompanying drawings, in which like characters of reference designate like parts in all the figures, I designotes the main truck, which is connected with the side truck ll: by a switch, as clearly shown in Figs. 1 and 2 of the drawings, by reference to which it will he seen that the switch-points l 2 are pivoted at 1 2, respectively, to steel plates 1" 2*, respectively, upon which they rest. The switch-points l 2 are connected to move in unison oy the rod or'bur 6, which rodv G is also connected with the rod 38 of the electrotnugnetic switcb-set ting apparatus inclosed in the housing 5, which wi l he more full referred to inter.

As conditions may require, &1 pit. 7" may he provided to receive the switcl1-point-c0oneeting rod and theswitchsctting inechanisni but when this the case it suitable olftake '7 cor 'tects with the hit 7 to draw oil any water which tour eccntnulite in the pit.

Disposed bciow t to base-pl 2" are electric heaters 1" it, respecti t, 3*, which are preferably tired directly to the hosepletes and have their t'ither or free surfaces covered by e suitnb material of poor hen;- conducting prtivperties in order that the hcztt generated by the heaters may be directly applied to the rsihpoints without. unnccesnry waste.

The semaphore-hitide i'n chunism is preferably inctosed in a ntettdhc easing 8, while the night-signal 1G is placed in ft supplernen' ta l easing 9, adjoining the casing S, and forming, as it were, t1 integral structure therewith. Both casings 8 and 9 are mounted as an integral structure on the top of it suitable pole 10 when the semaphore form of signed is used. 7

When my invention is used in connection with dwarf signals of the ordinary type, in which the signal coin rises two plates of different colors niountedhixially on a short vertical shaft and at right angles to each other, so as to rotate with the shaft through on tillgle of nii'tetydegrees, and in which a lantern of rectangular sh ape having different-colored windows is secured at the junction of saidplates, so that when turned into its locked position it will throw at corresponding and steady color-sigzml in the distance, the construction is substantially the saute us for the semaphore mechanism. The operating mechanism of the dwarl' signal is placed in it Weatherproof housing similar to that of the semaphore, described.

hen the switch-blades are in the position shown in Fig.- 1, so that it train amnoaehing from K in the direction of l) will be switched over to the siding H, the semaphore-blade is held horizontally, shown in Fig. 2, so as to indicate to trains approaching been set for the siding and that there is dunger for nt-ritin to approach further.

Referring now more particularly to Fig. 3 of the drawings, which designates disgruntnmticu-lly'th completenrrangeinent of my from L to-' 'ward the directlon of K thin the switch has improved system, it will be seen that the portion indicated below the ptirttllel lmrtzont-ul dot-und-dash lines constitutes the portion of my improved apparatus within the t)])01t1- tors station, which comprises the swit h-indicator A, the sigmtl-indicator B, the circuit :losing switch l), the re rersing ciunit-closing switch l, the currentdndlooting :i-mmeie-r 13, together with the eleetricnl connections between each of said ports and their electrical connections to the linc-wircs. The linewires, six in number, which connect the opera-tons station with the truck ttppemtus, are designated by the referenceletters M, M, M, M M", and M, and thee ires may be run either as uir-lines or they ':!tl Y be combined into one or more cables a cl run u nderground.

The indicator B not only indicates the position of the signals but also indicates defects in the line. The indit-ittot A not only indicates the position of the trackswitch, but :ilso'deiectsin its respect ive. line, as will be more fully understood hereinafter. The switch F is in the nature of it doublethrow reversittg-switch, and it has its lmil'ccontacts f" and 1 connected with the linewires M and M", respectively. The contact point e of the switch E and the contact-point fuses 14 and 15, respectively,withthe negative and positive bus-bars, (not shown,) respectively, of the power-station.

. The -ammeter 13 (shown in detail in Figs. 8

' and '9) comprises a casing in which the ammeter-o crating mechanism is mounted, all of which parts may be. of any a proved construction, with the exception tiiat I rovide the ammeter 13 with a few adjustab e indicating devices, (shown in detail in Figs. 8 and 9,) by reference to which it will be seen that on the cover-plate 104 are fastened, by means across the line-wires M and M.

of screws and milled nuts 11 1, three hands 105, 106, and 107, each one being concentrically mounted with respect to the s indle of the pointer 112 and each being capa le of being turned on the screw 110 with sufiicient clearness above .such pointer and the scale 104 of the instrument. To each hand 105, 106, and 107 isfastened a stud having a head 109 and a screw-shank 109 to'receive the mill-nut 108, and the said studs 109 are slidable in the curved slot 104 in the coverlate 104, thereby allowing adjustment 0 the hands to any desired position. The ends of the hands'105, 106, and 107 are squared and provided with small scales 105 106 and 107 to measure deflections of the pointer 112 from the adjusted position of the hands. A cover'1l3 may be placed over'the slot 104 f and secured to the-top, at 104 and 104, by small screws or otherwise to prevent entry of dust and dirt into the ammeter-casing. The rail-switch-setting apparatus (designated generally by'G in'Fig. 8 of the drawings) comprises a stationary magnetic field energized y a pair of field-magnet coils 27 27 connected in series with each other and Mounted to reciprocate between the coils 27 27 is an armature 28, provided with a pair of energizingcoils 31.31 connected in series with one another, and one, 31 connects, through a flexible conductor 31", to the main-linewire Mf, while the other coil, 31, has'its free terminal conductor 31 connected in series with the armature-coil 55 of the semaphore-operating mechanism, hereinafter again referred to, to the line-wire M The armature-coils 31 31 are wound in opposite directions to each other, so as to produce like magnetic poles at the opposite ends of the armature 29 47 47 designate circuit-closers operated by the movement of the armature 29, and v these circuit-closers 47 47 are normally held open by counterweights or springs, as shown in Fig. 3 qf.the drawings. One terminal of each circuit closer 47 47 is connected to- 'gether and to the cross-wire which connects the field-coils 27 27 together by a wire 81, in which a resistance 81 is joined. The other terminal of the circuit-closer 47 is connected to the line-wire M while the other terminal of the circuit-closer 47 connects with the line-wire M as shown. Each circuitcloser 47 and 47 is preferably constructed upon the principle of an angular lever with afulcrum atits center, itsvertical arm being engaged by the armature 29 and pushed back to cause its horizontal arm to make contact with a fixed terminal to close the circuit.

In its general features the switch-setting mechanism comprises a housing 5, in which the magnets 27 27 are immovably mounted on cores 5 and 5 which are bored out to form bearings for the axial rod 101 of the armature 29, which armature 29 carries the coils 31 31 hereinbefore referred to.

38 designates a rod reciprocatingly mount ed in bearings 5 5 of the casing 5, which is joined with the armature 29 by an arm 29 and screw 102 and which connects with the switch-rod 6 through a coupling 46, as shown.

Fulcrumed to a bracket 5 on a pivot 44 is a bracket 43, having bearing to receive a sliding rod 42, which rod 42 is provided with a co lar 42, between which and one of the bearings of the bracket 43' the coil-spring 45 9 5 is held. The rod 42 is pivoted at 103 to the rod 38. The members 42 and 43 and their connection with the rod 38 and casing-top 5 serve as a toggle-spring attachment for locking the switch-points to their final position when they have been set.

The rail-heaters 11 11 are preferably connected inseries in the main-line wire M between tlie switch-setting apparatus G and the line-wire M The semaphore mechanism H comprises a rotatable iron armature 55 of the Siemens shuttletype, upon which the armature-coil 55 is wound. The armature 55 is secured to the semaphore-shaft, which is journaled in the front and rear walls of the housing 8 and to which the signaling-arm 3 and tail-plate 3 of the semaphore-are attached.

53 and 53 designate a pair of stationary field-magnet coils for ,cooperating with the armature 55 and these coils are connected in series to produce north and south polarity anism G. p

The sump-switch 17 is preferebl mounted at any convenient place on the signal pole 10, so that the same nmy be operated to cut out the lamp to :md'cut in the resistance'lS, or vice verso, escondit-ions may require, it being understood that the ohmic resistance of the lamp l6 and that of the resistance 18 must be the some. The lamp 16 and resistance 18 are disposed Within the casing 9, as before mentiozrd.

When the armature 55 isin motion the keys cs 68'' are both set free and the circuit containing the lamp 16 is thereby opened. A protruction in this period or a failing of the contact melting devices would allow the blade from its position 3 to 3.

lamp to to remain cut out, and thereby cause severe accidents to happen. To overcome this, I provide it second lamp 71, which is inclosed in av colored lantern 4 of the somaphore-easing, which lamp 71 I connect across the terminals of the armature-coil 55 end in. parallel with the armature-coil 55*, the lam 71 being rated at a voltage equal to the dilference of potential at the terminals of the armature-coil 55 A small resistance or re actance coil 82, connected in series with the lamp 71', serves to compensate the excessive voltage and ilow of current at the moment of closing the armature-circuit, so as to protect the saidhnnp from injury-as, for example, supposing the semaphore-blade to be in an. inclined position (see Fig. 2) and the switch 12 closed, so that the stationary field-coils w 27* 27" ot' the switch apparatus G and those 53" 53 of the semaphore mechanism. H are excited, the armature 55 of the semaphore mechanism being in such a position with respect to the lield coils 53 53 that the moxi mum number of lines of force are traversing the said armature in the direction of 53" :1: 1 53. Now when the lever of the reversing switch i is thrown onto contacts ff timer-- mature ol' the rail-suitell-setting apparatus moves from right to lert'and the semaphorel coking the curn'a rd thc'pole y of the armature rent willllow clockwise in Wire turns of coil 55 and produce a magnetic llux in the dn'ec-' tron 1/ to :2: in the iron body of the armature, which hurt, because it is opposite to the lion ol' the (:O'ilS 53 53, causes the arnmture to rotate counterclockwise. Decreasing the magnetic field results in exciting an.'e'le 'tro-- motive force which causes a clockwise current to flow in the coil-windings when looking in the direction of the magnetic flux through the armature, and thereby ncreases the electrical potential at the terminal in the erma true :35. At the moment oi closing the eir c'uit by the switch F the lump tukesthc elec' trical pressure at the armature terminals, which will be equal to the drop in voltaee in the armature-coil. (due to its internal resistance) plus the inductive elcctromotive force, whose strength depends. on the nunrher of wire turns, which Weaken the active fieldot' the magneticcircuitand the time in. which the change is brought about. (The-coils ofthe armature 29 of the switch-settingnpparatus G. will cause no inductive reactionin the ernmture, as said coils are Wou1i lii roppQ site directions to each other.)

Supposing the number of'turn's in the armature-coil to equal eight hundred, the mini her of lines of force produced in this coil (by 2L workin"currcntof 4.4 ampcreSin thisbriinch) to equal forty thousand centimeter grain secv end-units, the time of changing the flux by this amount assumed to be one-fifteenth of a second, copper resistancewl' arnutture-coil to amount to nine ohms, then the effective volts. In this case an incandescent lamp rated at forty. volts would be used, (because 39.6 volts is the electrical pressure at the armature-terminals after the inductive action. of the coils has ceased,) and in view of the fact that excessive voltage shortens the life of a lamp, particularly when the lamp is cut in. and out many times a day, a small reactance-coii 82 is connected in circuit with the lamp 7* to absorb the eleven per cent. of ex-.

CGSSIVL voltage at the moment of closing the armature-circuit.

Having thus generally described the circuits and operative arrangement of the parts constituting my complete system, I shall now proceed to explain in detail the consecutive steps of operation thereof.

Operation: Assume that a night-train is expected to come over track L in the direction from L to K and the position of the railv switch and semaphore-blade being as shown in Figs. land 2. As the track Iis still broken by the switch-points 1 and 2, (being set to direct a train into the siding,) the signal-arm 3 of the semaphore stands in a horizontal position and the colored-glass disk in the tailplate 3, which plate is in conjunction with the signaling-arm 3, covers the rear opening in the casing 9, thereby throwing a coloredlight signal in the direction toward L to warn the engineer of an approaching train that there is danger. The armature 29 of the switch-setting apparatus G is now in the po-,

sition shown in Fig. 3, whereby the circuitcloser 4:7 is closing a branch circuit from the double-pole-reversingswitch F, through the coil 19*, the line-wire M, the resistapce 81, the wire 81, the field-coil 27 and the mainline return-wire M. At the same time an additional current from switch F I "passes through the coil 19 of the indicator A and linew1re M to the terminal block ofthe semaphore-armature, where it is 'split, into two branches, one part of the current passing through the armature-windings 5-5?, the other part passing through the lamp 71 and resistance-coil 82, so that thesum of both; currents will flow through wire Mfl the armature-coils 31 31 of the switch-setting appa-- ratus, the line'wire M the coil 19 er the indicator A, the other pole f of the reversing switch F, to the main return-wire M". It Is obvious that under these conditions the coil 19*" is producing a stronger magnetic pull toward thearmature 23 than the coil 19", and therefore the armature 23 is moved into the position shown in Fig. 3 to direct its pointer 25 over the indicating member II to signify that the side track II is free for passage while the main track I is broken. Another current is passing at the same time through the main wire M and the electrical heaters 11 11 to a main terminal plate inside of the housing 5 of the switch-setting apparatus G,

where it is divided into two branch circuits,

one ortion of the current passing through the held-coils 27 27 b and the other portion through the line-wire M to the semaphore apparatus in the semaphore-housing 8, Where the current again divides as follows, one portion passing through the lamp 16 to the contact 17 and across theswitch 17, through wire 83, to the circuit-closer 68*, which bein closed permits the current to flow throug line-wire M and coil '20 of the indicator B to contact e of the switch E across the switchblade to contact e and through fuse 14 to the negative bus-bar of the power-station. An other I ortion of the current passes through the fie coils 53 53 of the semaphore-open ating mechanism to the line-Wire M and through the line-wire M and switch E to the ne ative bus-bar of the power-station.

en, however, the switch 17 is turned to close with the contact 17*, the portion of thecurrent which was flowing through lam 16 will then flow through resistance 18, an the lamp 16 will be cut out. As the current flows through the coil 20 the armature 24 will be attracted toward the right until its indicator 26 points to the dial-letter D to indicate that the semaphore-blade is in its horizontal position, to which it has just been moved, it

eing understood that the toggle devices connected with the armature of the sema horeoperating mechanism, together with he action of the magnetical fields of the armaturecoil 55* and the field-coils 53 and 53 sustain the semaphore-blade in its set position. In the switch-settin apparatus G a ma netic field of constant po la ity is produced %y its two field-coils, so that,'f0r instance, the in' side end of the coil 27 a forms a south pole and that of the coil 27 a north pole. In order to force the armature 29 into the left-handed osition, as shown in Fig. 3, its outer ends liad to be rendered with north magnetic poles, which was done by throwing thelever of the reversing-switch F into the position shown in Fig, 3 to engage with the contacts When the switch 12 is open, the ourrent-flow through coil 27", 53, and 53 is reduced to a minimum, while still 'a somewhat stronger current from the line-wire M through the heaters 11 11 is passing the field-coil 27*, wire 81*, resistance 81, and then joimn the main branch flow in the armature-win reading of the ammeter 13, which shows a reduced current consini'iption. Alter llhhlb ing the urnmime-circuit h in the lever 01" the switch l" t he zirnnitur .3 l the indie: tor A. will drop to its perpendienlar positiani. whereas the armature 25) of the switch .i ling apparatus and the armature 5;)" ol the senmphore :nm-lninism remain in their said positions, due to the action of their togglenspriii devices. and a small current will pass through the line M healers ll" 11*, line-ire ll. lump 16, switch 17. Wire 83, circuit--eloser es, line-wire M coil 20 of the indirutor ll. throng-h contaets e of M e2 in, and lose l-l lo-the negative hushur oi the station. The lamp 1.6 will therebe ghted. The armature 24 of the indiemor B si ul points to the in.dicai;ing-letter "D" on ihc indwatlug-plate to indicate d and {he annneter 13 indicates the intern ol current consumed by the lamp 16,

'iho la on 3 however, heingnow e i-inguisshed. he r i \lillS informed of the condition i re nieelnmism, and by again in thc switch F and by observing there-11o o of the indicator A. and the aminoter 13 he can determine the condilion of the iracleswitch. Should any of the apparatus in eonneot ion with the line H or M suddenly fail in it lunctions for instance, should the lump 1 burn outl-the urn'iat-ure 2% ol the indicator B will take perpendicular position and the hand of th aronieler 123 will rest, at its zero-mark. in such exceptional cases the signal operator will have the apparatus such condition inspected and until the fault; is remedied he will throw the lever of the reversing-switch F back into its former position to close with contactsff, thereby relight-ing lsrop 71 in lantern 4, thus giving a Warningznal to the approaching train. Supposing .iw that the track I is to be opened and arranged for an arriving train from L, the signal operator will first close the switch E in case the planthad been shut off from the current-supply source, whereupon blie annneter 13 shows the amountof current taken by signal-lamp 16. The indicator B will then point to the index D to indicate danger, and thus nssures the operator thatthe somaphore-arin is in its horizontal or dan er-indicating position and the colored-glass fiisk of the ta'l plate 3 covers the lamp 16 to also in dice danger. BY thus closing the switch 12 the magnetic. fields of the switch-setting apparatus 6- and the semaphore mechanism H will be exeited i. 6., a flux of lines offoree will take its way througl'i the srniatures 29 and 55" in the direction-3i 27 to 27 and 53 to 53. That the said circuit is perfect and that the lields me excited is shown by the increased deflection of the anirnet-er 13, the hand 01" which should coincide with the distinctlymarked index upon its sealel By throvrine the lover of the reversing-switch l I scale of the animeler 1Z3 they must consist either of distinguishing divisiondiner? on the smile of the instrument or they may he in the nature of small plates with engraved indexlines, as shown in Figs. 8 and 9, which plates sliouldhe adjustable upon the scale and provided with n ans for securing them in their lustod positions with reference to the scale. Lne various indexes of the arnnietor 13 are set to the normal reading of the inslvrurnent, so that when current, is flowing in the amineter 13 the operator can readily cell whether the system is using the normal amount of en rent by observing whether the iointer of the armneter 13 corresponds to toe proper indicating-mark on the ammetenindeoc, and therefore he is able to determine whether or not, the system is in is normal condition. Owing to the rw'ersed eiu'rent ol the armature-riinuit the coils I31 31 of the switch-setting apparatus G will render the outer ends of the armature 29 south poles. consequently moving the armature to the right to release the circuit-closer 47" and close the circuit at cireniheloser -17" to Form n ln-armlreircuit iron; the line-wire ll, eonl'aotsjflj' andf oiswitoh l through the (oll l9", line-wire M :ir(' i.iii -rloser 47", resistance 81., wire 81,

Under this arrangement the magnetic held of the coil 19" exceeds that of the coil 19 sot-hat the armature .33 of the indicator A is pulled to the right, as shown in dolled lines in'Fig. 3, so that-its pointer 25 coincides with the indiesling-letter l on the dial and indicates that the railswitch has arranged track I for trallic, as required. At the instant that the coils of the armature 29 are energized a flux of lines of force in the sen::rphorearinstore 55 is also produced by the coil 55, and as this magnetic flux is across the armature-field in the direction m to g -'i. 6., in the same directiorras the flow of magnetism through the stationary coils 53 53---t-he armature will he turned clockwise until the semaphore-blade reaches the position at 3* (shown in Fig. 2) and the lever 55 releases the circuit-closer 6S" and closes the circuit st the eircuiteloser 68*, thereby closin the circuit through the lamp 16, snapswitch 17, wire 83, circuit-closer 68", llnewire M, coil 2W of the indicator B, and return wire to the ourront source.

is changed from one contact 17 to the other contact 17*, thus altering the balance of the indicator and causing a fluctuation in the movement thereof which can be observed by the signal operator.

The principal object of switch 12 is to open and close the heating and field circuits for any period of time without causing changes in the signals.
