To all whom-it mag/concern.-

Be it known that I, RIo Aim VARLEY, a citizen of the United States of America, residing at Englewoo-d, in the county of Bergen and State of New Jersey, havein vented new and useful Improvements in Electrical Systems, of which the following is a full,-clear, and exact description, referonce being had to the accompanying drawings, which form part of this specification. This invention relates to systems for producing electrical discharges from a source of energy. As such a device I provide means for causing a high tension effectively sustained discharge of current without employ- 'mentof large and heavy apparatus, and

which may find embodiment in" many systems', such as wireless telegraphy and ignition systems for exploding the chargesof intern'al'combustion engines.

The broad feature, herein disclosed, of

building up a supernormal state of flux for prolongedenergizing of a currentusing instrumentality is covered by Patent .No. 1,081,413, granted to me December 16th, 1913, and to divisional subject matter of 'whichthe present application is directed. In the accompanying drawings hereinafter described I have illustrated my invention as embodied in an ignition system for internal combustion engines but it will be premised that I do not desire to limit myself thereto, said embodiment behig only one of the many-uses of which my invention is capable. Y Y

The usual ignition systemlemployingi a coil or generator inductively. wound pro duces a high voltage spark of short duration, and loW heat, and therefore, poor ignitive value. This is due to the radical magneti'ping and demagnetizing effect. upon the core or armature of the inductive generator upon breaking of the primary circuit, and

resultant nonssustained magnetic flux action; the momentarily induced current in the secondary winding producing a correspondingly short ineffective spark, and while in the alter-1 nating current high tension magneto or .generator there s a. certain amqunt-ofcurrent an gmentatively, generatively impressed upon the secondary windingof the armature, by 1 reason. of itsrotation, after-the primary cirvently, disposed cuitzhas been interrupted, its amperage is so sllght that it is practically impotent. It 1s also commohly known that in the usual ignition system, self-induction and reactance in the interrupted primary winding,

also requires a condenser or other spa rk I arresting means connected across said contacts,- -for absorpt on of such extra or self-. induced current, ,as a protection to the contaots.

By my invention there may be readily formed a spark having the character substantially of arc-sustenance andhigh heat .value ascontra-distinguished from'the instantaneously gdelivered low heat spark above referred to, thereby producing aspark operatively alive for a greater period of time relatively to the travel of the piston, than heretoforehas been possible and thus making it eifective'upon thin .or weak gas mixtures and such charges as contain. oecluded dead or weak spots. Furthermore, I provide a system in which I may dispense with the condenser or'other spark arresting means. I

a -My invention comprises, broadly stated, the combination with a source of current, oftransfo-rmer means and mechanism for effecting the energizing of and for so con trolling the transformer with respect to the source .of current as to cause operative sustained energizing of a current usin' instrumentality, as prolonged bridging o aspark gap, in the manner'to be fully described.

Figure .1 1n the accompanying drawings "illustrates, in diagram invention as employed in connect on with an ignition systern, said diagram- Showing a'multi'polar '9 O hereinafter more or high frequency generator and a battery as the source or sources of energy; Fig. 2,is a dlagrammatic viewv of the transformer element but showing thef-iuvindf spdifierv as will be-here'ma ter more fully described.

. While Lshowa magneto generatorof the highdrequeney type,;the:,same being one ,of'

the many types of inductive or magneto generators for ignition service on autovehicles, I do not desire to limit my invention to the employment of any particular type of generator or means afl'ording a source of current, as my device is advantageously operable with different current generating devices or with a battery or accumulator, as the sourceof energy; 1 r

The alternating current generator, which is indicated by the numeral 2 in Fig. 1, (preferably being'of the standard type for a four cylinder four cycle engine) has its ignition energizing circuit or inductive winding grounded at one end, as at .3, while the other end is adapted to connect through switch mechanism 4 to winding of transformer mechanism 5, forming part of the spark producing apparatus shown. The transformer device comprises a core 6-which may be of any suitable shape or construction, and which carries on the-legs?- and 8 thereof windings 9 and 10 respectively both of which are arranged to be grounded, as

at--11, through the intermediary'of circuit controllin mechanism 12 which may comp se a ro le'rutiiner of the usual construcofsymmetricall L Y tacts 14': each 0 which connects w h said tion, having essentially a --revolub1e contact arm 13, geared or connected to'be driven in synchronism by the engine, and a plurality arranged segmental 6onwindings 9 and 10 0f the transfo er; it

a beingunderstood that for 'a four cylinder four cycle engine, the controller arm 13 will bfl' driven at one-half the speed of themgine'to commensurately establish the circuit 1 of the windings for the purpQSe hereinafter described. A so carrie upon the f legs 7 "ind 8' of the transformer core '6' are sec ondarywindings a and 6 preferably serially arranged,fione end connecting with the segments '14 ,of the controller 12 and the other "*"end "connecting with a rotating contact arm 27- of-rusual distribut ermechanism 28 of the- 'Yibratorfmechanism' 15 is provided for in-v v .terrupti'ng one or both of the primary windings ;,8 and 9 of the'transformer when the Wise completed through the controlling spark producing apparatus, the contacts 29 of which'distributer connect withthe usual sparkplugsBO ofan engine (not shown)- that are grounded through the cylinders of 15o I the engineas is" understood.

Angelectrically responsive interrupter or circuit or circuits of said windings are other- .iin'echanism 112. The arrangement is' such t1 the'ivibrator isjconnected in active cir- "ftli'e windings"9 and 10 of thetransmen 'uringfutilization of a' battery or us current,. .and; serves as an interreferablyi op'eratively responsive to 1 e mpeake or period of flow of the imam alternating current, for one of said primary windings (winding 10) when the transformer is connected in the generator circuit. 'A switch arm 4: of the double-arm switch 4'connects with one end of vibrator winding 16. The opposite end of said winding leads to a vibrator contact 17 and a contact" 18 of said switch. Normally in engagement with the vibrator contact 17 is a vibrator .blade or armature 19 which is in the circuit of the coil or winding 10 and connects with a switch contact 20. When the double arm switch is shifted to a contact 21 and the contact 18, the vibrator winding is connected to the generator through the switch arm 4. Movement of the roller timer arm 13 to a segmental contact 14 will complete the generator circuit through the primary windings 9 and 10 of the transformer. That is, current flow from the generator will be through switch arm 4 and vibrator winding, thence in parallel through switch contact 18 and a switch arm 4 of the switch and transformer winding 9, and

transformer core 6, which tends to seek the normal magnetic path of the core. The turns of windings of these coils 9 and 10 are unidirectionally wound with the result that the lines of force set up respectively by these two coils meet one another in opposition at an intermediate point in the core, causing them to take an abnormal path. The

abnormal path taken is preferably a megnetically reluctant one, as by employinga core, such as shown, in which the flux, upon saturation of thecore, takes a leakage path across an air gap or space intermediate the sides of the transformer. As the generator current rises to maximum value, the armature 19 of the vibrator is responsively attracted, through energizingof the winding 15, causing sudden opening of the circuit of the coil or winding 10. As stated above, the point of opening of the circuit may take place at or near the peak or maximum point oF-periodof flow of the current wave. Opening of the'circuit of the winding 10 causes a violent change of flux in the leg 8 and the divertedor repressed flux takes the less resistant or normalpath provided by the core, setting up a magnetic surge of great intensity, particularly through the leg 8. r

causes a rise in voltage in the winding,9.' As a result of said flux change and magnetic surge, the voltage is immediately generatively built .up to an intense degree in the secondary coils or windings a and b of thet-ransformer, breaking down or bridging the air gap between the electrodes ortermmals of the spark plug connected, by the distributer, in the circuit of the secondary windings. The spark thus formed is not a mere instantaneous flash or of brief duration, but it continues to burn substantially in the form of a flaming are maintained by a resident body of flux in the core, for the breaking down of the normal reluctance of the spark gap and inauguration of the spark or are in efi'ect causes a closing of the circuit containing the secondary coils or windings, with the result that there is established a mutual or reciprocal regulative relationship between thearc and secondary winding or How of flux Which tends to prevent immediate equalization of the flux or dema etization or dissipation of the energy of t e transformer; the

are assuming a rheostatic function and causing the windings a and b t0,,sub'stantially choke or restrain the large body of flux in such a manner as toprolong its activitywith respect to are or flame maintenance at plug. Furthermore, the winding 9- fcon-' tinues to suppl energy at a slight increase; in voltage, to t e core 6 and to generatively; impress a current, in the particular arrange ment shown, upon the secondary coil or winding a, assistive or additive to the normal current in the secondary winding set up or induced by the flux in the transformer core.

Instantaneous establishment of'the spark at the plug or other current using instrument and its maintained 2 utilization of energy causes the active seconda circuitv containing said instrument, to so a sorb the energy and control the flux action as to preventself-inductance of a sparking current in the circuit containing the contacts of the interrupter or vibrator mechanism. As a result, there is little or no tendency to sparking between the said contacts upon opening of the circuit of the winding 10. I am thus enabled toemploy ordinary material, such as copper, for the above parts, and to dispense with .the use of a condenser or other the ordinary systems to absorb the sparking resulting from interruption of a primary circuit. However, I do not desire to limit my invention to a system in which no condenser is employed, for a condenser may be necessary in some cases, as where abnormal conditions obtain in 'the circuits. I have, therefore, indicated sucha condenser 22 connected across the contacts of the vibrator mechanism in the usual manner.

.When the switch mechanism 4 is shifted to contact 20" anda contact 23, connections are made fhr ener 'zing the transformer rent, such 'as a battery, when the generator is not deliverin an efi'ective alternating 'current or whenit is desired to run'on battery ignition. Shifting of the switch as stated, to "position shown in-dotted lines, brings the vibrator mechanism 15 into cirthe transformer, and when the roller timer arm 13 connects with a segment 14 the battery current sets up amagnetic flux in the core 6 of the respective transformer, which is trembled or intermittently disturbed by the vibrator mechanism, thus inducing a high potential current in the secondary wind-- ings a and b for energizing of the spark plug or plugs 30; the battery being grounded as at 25, pin CiI'CllltfWith ground 11 of the roller timfcr contact arm 13.

. \Vhere my system is employed in connection with a-high frequency alternating current generator, such as indicated, the gage or size of the turns of the windings 9 and 10 of the transformer would be preferably such as to present no resistance impeditlve to efiective flow therethrough of the high frequency current. The result is that such windings would not present a desired resistance to the direct or continuous current of pating action on the battery, incident to said capacity effect of the windings, I may insert a resistance in the battery circuit.- Such a resistance is indicated by the numeral 26 and may beef any suitable character, the same being commonly connected to or arrange former windings 9 and 10, when the battery made and bein out of circuit with said windings whent e generator connections are rangement 4.
