specification.

This invention relates to electrical systems, more particularly tothe provision of means for exploding the combustible mixture in thecylinders of an engine.

The general object of this invention is to provide a new and improved form of ignition system and apparatus which shall be effectively responsive to the requirements. of the modern internal combustion engine of the equipment of autovehicles and which shall be flexible in control. The attainment of this end and other advantages, hereafter apparent, are afforded by the folowing provisions and by other features of constructions to be hereinafter more fully set forth:

The provision of a system and apparatus employing interrupter or timer mechanism, the contact elements of which are relieved from contactual activity, by occupying a non-operative position, during non-use of the ignition circuit of which said mechanism is an element and when energized by another ignition circuit, as that of a magneto generator;

Means whereby movement of the contact mechanism into operative vposition shall otherwise close or effect completion-of the ignition circuits;

arrangement wherein the contact mechanism may be automatically brought to operative position upon spark adjustment of the interrupter or timer in the direction of retard or advance positions;

An ignition system and apparatus in which the spark 'coil or transformer mechanism is automatically brought out of drain ing or dissipating connection with the usual battery or accumulator of the equipment upon stopping of the engine;

Means whereby the contact mechanism of the interrupter or timer is restored to its normal inoperative position automatically upon disconnection of the spark coil or Specification of Letters Patent;

transformer from the ignition circuit upon stopping of the engine.

A system employing a single (listributer mechanism and'means for connecting the high tension winding of either the continuous or battery ignition circuit or the magneto generator to the distributer and also by spark adjustment of interrupter or timer apparatus or upon movement of the contact mechanism of the aforesaid interrupter or timer into and out of operative position;

and

Circuit and switch or controlling means whereby a continuous or battery ignition circuit and an alternatingcurrent ignition a regular magneto, may operate in parallel or unison and when the latter circuit becomes ineflicient or non-operative during operation of the engine, the other circuit shall responsively operate in a superinductive or sessional capacity.

In the I have had in mind the primary, requirement of affording effective ignition at all. speeds of the modern high speed internal combustion engine of the equipment of autovehicles. Such equipment usually employs a magneto generator, and it has been found that when this magneto is driven at low speeds, such as obtain at or just after starting of the engine, it fails to deliver an effective sparking current, and that when it is driven at high speeds, the magnetic flux of its field shifts in such manner as to destroy substantial coincidence between the current peak and the desired moment of ignition .or time of delivery of the spark at the plug, the current wave peak shifting to an impotent position.

By my invention it is possible to cut in the battery 'or continuous current ignition circuit merely by shifting the interrupter or timer mechanism of that circuit in the direction of spark retard or advance. In the particular arrangement shown and hereafter described, I provide means for completing, during starting of the engine, the battery ignition circuit in elude or render ineffective, during starting, the means for establishing said battery circuit by spark adjusting movement of the interrupter or timer for the reason that assomated with the last named mechanism is resistive or a super provision of the last named means.

such manner as to exmeans for disconnecting the spark coil or ately upon assumption mechanism diagrammatically illustrated in of the engine. starting it is customary to adjust the battery ignition interrupter or timer for spark retard to prevent premature firing, immedithe engine, resultant automatic connecting in of the battery completes the ignition'circuit otherwise closed by previous adjustment of the interrupter or timer to f spark retard. Should the magneto generator of the system subsequently develop ineificiency in-approach to high'speed or to low speed, I can establish, by spark advance or spark retard respectively, of the interrupter or timer, as above stated, the auxiliary or battery or continuous current ignition circuit and without disturbing the otherwise preformed or established circuit connections of the magneto generator.

-The above mentioned and, other advant'ages will more fully appear in the following description of my invention, which I will now make in connection'with the accompanying drawings, so that others skilled in the art to which it appertains may under: stand and construct the same, it being premised, however, that many changes maybe made in the various structures shown and v circuit arrangements therein largely diagrammatically illustrated, without departing from In invention.

have shown-my invention in connection wlth an electric generator 2 adapted to a supply current to a light or work circuit 3 and to charge a battery (accumulator) 4. This generator has serles and shunt field windings 5 and 6, respectively, that are connected to olppose each other. The numeral 7 indicates core of a magnetic cut out or relay, having winding in circuit with shunt field winding of the generator and consisting, preferably, of afine. wire coil 8 and a heavy series coil 9 which have I tact connection at 10, with which contact is adapted to co-act a contact member 11 carried by and electrically connected to a pivotally mounted armature 12 connected in the batterycircuit. Connected to the armature 12 is a suitable spring 13 which operates to 10 and 11 at low engine speeds. I The spark coil or transformer of a. continuous or battery ignition circuit, as conamagneto or alternating current circuit, is indicated at 14 and comprises a usual and a high tension or secondary winding '16 revoluble arm 17 symmetrically disposed segments or contacts 19 of which connect with spark plugs of the engine (not shown), in the usual manner, as by leads 20. One end primary winding 15 connects with; the battery 4 while the other end is connected to a core 21 0f an electromagnet 22, having ener-,

gizing winding 22. Saidmagnet in this a common terminal conof the u particular instance is mounted in and its core 4 insulated from the casing or housing 23 of timer mechanism ,(clearly tially a. fixed contact 24, a relatlvely yieldable contact or movable lever 25 and contact actuating means. Connected across said contacts is a-usual condenser 25. 24 and lever 25, normally in contactual union, are carried by an insulated mounting 26 pivoted in the casing 23, as at 27, and the contact 24: is -mounted on anextens'ion of or electrically connected to an arm 28 of the pivotal member 26, while the contact lever 25 is grounded, as at 29. The arm 28 constitutes an armature for the magnet 22, attraction by which of the arm, plvotally moves the member 26-to such positlon as to present the contact lever, 25 to an actuating cam .30 (properly synchronously driven by the engine through suitable gear connection, not shown), against the action of a spring 31 which serves upon and during demagnetization of the magnet 22, to return and normally hold the armature 28 against a stop 32 and the contact lever 25 out of the path of the projecting noses of the actuating cam. With the magnet core The contact 21 connected in the circuit of the primary winding of the spark coil, attraction of the armature 28 and contact thereof with the core completes, from the battery, through the primary winding 15 of the spark coil,

contacts 24 and 25, and ground 29 and batteryground 33, a primary ignition circuit subject to periodical interruption by operative-separation of the contacts 24 and by the action of the cam 30 on the latter yieldable contact or lever 25, for the production of a high potential sparking cur rent in the secondary winding of the spark coil, as is understood.

By means of switch mechanism'34 control of the battery ignition circuitis effected and also, as herinafter set forth, the control of certain more or less interdependently related elements of the equipment of an autovehicle. This switch mechanism 34 which may be'mounted at any convenientplace on the vehicle, comprises an insulated base or support 35 that carries contact blades 36, 37, 38, 39 and 40 grouped about a pivotal switch block 41 carrying contact fingers 42, 43 and 44 grounded,

as at 45, and insulated bridging contact blades 46 and 47. The pivotal switch member 41 is provided with a suitable manipulating handle 48. The movable contacts 42 and 43 are adapted to co-act with contact finger or blade 40 for grounding a magneto generator 49 "of the iequipmen-t jwhen it is desired to cut out that element,

as hereinafter set forth. Theimovable contact member 44 is adapted, by engagement, with the contact 36, to connect the winding of the interrupter magnet 22in grounded circuit with the battery, while contact 46 when shifted to bridge the contacts 36 and 37 also connects, as hereinafter more fully described, the magnet winding 22 with the battery and in circuit with winding 9 of the generator relay or cut out above described. Bridging of contacts 38 and 39 by the con tact member 47 brings the battery, into energizing connection withengine starting mechanism or controlling apparatus for such starting mechanism (not shown), as

by lead 50.

When it is desired to start the engine the switch arm 48 is shifted to move switch body or block 41 against the tension of a spring 51, to a position where contact 47 will bridge, or connect contacts 38 and 39. This position for the arm 48, is indicated by S on the index plate of the switch structure shown in the drawing. Bridging of the contacts 38 and 39 connects in battery circuit, and setsup operation of, the engine starting apparatus, or its control for turning over or initial driving of the engine. Movement of the switch to S or engine starting position, brings contact 44 into engagement with the contact 36 of the r V position, with resultant ing. thereof,

switch with the result that the winding 22 of the interrupter magnet 22 is connected in the battery circuit, resulting in attractive pull of the armature 28 into contact with the magnet core 21, shifting of the interrupter contact lever'25 into operative juxtaposition to the actuating cam 30, and the establishment of a battery primary igni tion circuit for utilization during starting of the engine.

Upon picking up or assumption of selfpropulsion of the engine, the switch arm 48 is released and the spring 51 returns the switch member 41 to M or magneto position, breaking the connection between contacts 39 and 47 andcausi contact 44 to pass from contact finger 36. It willbe assumed that the interrupter or timer casing 23 has been so shifted as to obtain theing of the generator 2 by the engine, causes energizing of thecoils 8 and 9 of the aforesaid magnetic cut out or relay and resultant attraction of the relay armature 12 in such manner as to effect engagement of the relay.

contacts lO and 11. By the provision of switch means, as hereinafter fully set forth,

occupation of the interrupter of spark retard, position brings or maintains, as through 1eads'36-, 37 and 37 and coil 9 of the magnetic cut out or relay, the magnet winding 22 in closed circuit with the battery, so that whenswitch contact 44 passes from contact finger 36 in the breaking of engine starting connection, in the manner above set forth, the interrupter or timer mechanism of the battery or continuous current ignition circuit remains operative. It therefore will be seen that initial driving of the engine may be made on battery ignition and until such time as the magneto generator delivers effective sparking current. When it is desired to discontinue use of the magneto generator 49, the switch arm 48 may be shifted to a position to bring the contact finger 42 into engagement with the contact blade 40 or to 01$ short circuiting grounding of the magneto.

Shifting of the switch arm 48 so as to cause bridging of the contacts 36 and 37 by the contact 46 orcto MB or magnetobattery -position, moves the contact finger 42 from the contact 40, restoring the magneto to operative condition by ungroundand connects the interrupter magnet 22 into energizing relationship with the battery, which, it will be assumed, is now in circuit with the active lighting generator and-the coil 9 of the battery or gene erator cut-out or interrupter or erates in a supplementary capacity. Thus 'tacts or terminals 36 and 37 and brings the contact 43 into engagement with contact finger 40, resulting in the establishment of operative conditions in the battery or continuous current circuit, above described,

and grounding of the magneto,

As stated above,'a magneto generator is usually inefiective at low speeds of the engine, and for many reasons which are well understood and needinot be here stated, alternating current, supplied by the magneto generator, for ignition purpose, is desirable during normal running of the en-' gme. However, increase in speed of the engine, and resultant driving of the magneto at correspondingly advancedcspeed, sets up shifting ofthe magnetic flux or field of the magneto to a degree greater thanthe normal or possible angular advance adjustment of the circuit interrupting means, such shifting resulting in movement of the current wave peak to a position materially out of synchronism or coincidence with the desired moment of ignition.

As stated above, I have provided switch mechanism whereby occupation of the interrupter or timer mechanism of the battery circuit of spark retard position, as incident to starting of the engine, completes a circuit for the controlling magnet coil22 when the primary winding 15 of the spark coil is connected in, the battery circuit through out out or relay winding 9. Such switch mechanism, however, is not limited in function to the establishment of a bat-' teryignition circuit during initial operation ofltheengine, but is designed to cut in the battery or continuous current rimary ignition circuit when the magneto generator develops weakness at high speed or at low speed of the engine andaccord ingly. by merely making adjustment of the timer mechanism in the direction of spark advance or retard. This mechanism includes, essentially, insulated double contact mechanism 52and an insulated relaupon advance or tively movable contact 53, carried, as indicated, by a movable element of spark adjusting means.

retard movement in adjustment of the interrupter mechanism, establishes a shunt circuit around the switch contacts 36 and 37, through leads 36 and into circuit Shifting of the contact 53,

clearly set forth in a which passes need be no for housing 55 which of distributer mechanism,

the assumption of lower speed, it being necessary to shift the interrupter mechanism to spark retard position before the continuous current ignition circuit can be established. Furthermore it will be seen that these connections are made without disturbing the magneto switch connections, so tha there ber 41- preparatory to natural restoration or recovery of the magneto to normal condition. f r

The degree of advance or retard at which the continuous current ignition circuit may be out in by spark adjustment of the interrupter or timer mechanism, is preferably such in each case as to establish the .continuous current ignition circuit at a suitable point intermediate full advance and retard not only so as to be efiectively responsive to initial development of weakness in the magneto, but to permit of the use of said continuous current in flexible manner through proper spark adjustment. This implies the maintenance of .the closed shunt circuit of themagnet winding 22* during further spark adjustment of the interrupter or timer after the establishment of such circuit, by the provision of a yieldable switch arrangement, and I provide such means by the employment of the interrupter or timer construction indicated in Fig. land more Figs. 4: 5, 6 and 7 Referring mgre particularly to these latter views, the contact elements'in the casing 23 are more directly carried or housed by a shell member 5A nesting in an outer casing is connected the usual distributer casing 56 uter mechanism 18, indicated in Fig. 1. The casing 55 is provided with a usual base 57 (see Figs. 5 and 6) recessed to pivotally fit the top of a.support or bearing 58 through the actuating shaft 59 of the interrupter or contact cam 30. A friction clamp or anti-rattling device 60 urges the base 57 to its seat. This means comprises a spring 61 interposed between the top face of the base 57' and a washer or abutment 62 on a pin or stud 63 fixedly"carried by the support 58 and extending up through an opening 63' in the base or platform 57. This supports or to which.

such as distribmanipulationlof the switch memited pivotal the base of the tion devices, comprising a pin 63 'dependopening 63 is elongated to permit of limmovement of the timer casing 55 relatively to the shaft 59, and carried by the base is a post or stud 64 connected to which and the fiXed stud 63 is a contractile spring 65 which tends to hold the timer casing 55 in fixed (preferably full retard) position so that the inner timer shell 54 may be pivotally shifted for rotative adjustment of the contact lever relatively to the cam for limited or normal spark advance and retard without attending shifting of the outer casing 55 carrying the distributer casing 56. The inner casing 54 is yieldably clamped to outer casing by suitable fricing from the shell 54 through elongated concentric slots 63 (see Fig. 4) formed in the bottom of the outer casing 55, and a spring 61 interposed between the bottom of the outer casing it being understood that the slots are suificiently elongated and the clamping members are under such tension as will permit of movement of the shell 54 within the outer casing 55, as stated, without resultant moving of the latter casing, which shifting of the inner casing may be effected radial arm 66 which connects with the inner casing, as clearly shown in Figs. 5 and 7 through a slot concentrically formed in the bottom of the outer casing 55.

The insulated switch contact or finger 53 of the interrupter mechanismis so carried by the timer or interrupter as to be movable with movement of the inner casing 54 while the double contact 52 is shown as comprising an insulated post 67 carried by the floor or bottomwall of the outer casing 55 and extending up through an arcuate opening 68 in the bottom of the inner shell 54 and provided with spaced resilient contact fingers 69 and 70.

It will readily be seen that pivotal shifting of the inner casing or shell 54 will bring the contact finger or post 53 into engagement with either yieldable finger 69 or 70 according to whether the arm 66 'is shifted in the direction of spark advance or retard.

As stated above the'degree of rotative adjustable movement (which may be controlled by the length of the slots 63 or the opemng 67 of the inner casing 54 should be sufiicient to obtain spark adjustment within the range of normal running speed. As a result, the distributer 56 remains stationary during the greater part of the time of operation of the engine, and thus there is no eX tended working back and forth of the spark plug leads or cords at their juncture with the distributer box or casing with attending wear and liability to disturbance of terminal connections. When the independent movement of the inner shell 54, in sparkand a head or abutment 62 on in any desired manner, as by means-of a contact lever 25 tion.

The system and mechanism described .above concerns that type of system wherein the spark is formed, in the battery ignition circuit, by the interruption of a primary circuit and resultant building up of a high potential sparking current in the secondary winding or coil to which is connected the distributer mechanism. It will be apparent that the principle of my invention will not be departed from but may be readily'embodied in a system in which the spark is formed by the closing of a primary circuit intercalated in which may be suitable buzzer or vibrator mechanism for the purpose of trembling the current and causing the formation of a cascade of sparks at the terminals of the plugs. I have indicated such system in Fig. 2 which diagrammatically is the same as Fig. 1, with the exception that a modifiedform of timer apparatus and vibrator mechanism is shown in connection with the primary circuit. To obviate repetition of description of the essential parts and operation thereof, except as hereinafter set forth, like reference numerals are used to indicate like or similar parts.

In this Fig. 2 (also see Fig. 8) the timer contact mechanism comprises a yieldable carried by a pivotal support 26, properly insulated, and provided 1 0 with an arm 28 which corresponds in function with the arm 28 described above. Energizing of the timer magnet 22 attracts the arm 28 against the action of spring 31', moving the timer contact blade or finger 25 into position for contactual engagement thereof by a positively driven contact came 30, grounded at 29. This contact 25 and the cam 30 constitute the means by which the circuit of the primary coil or winding 12o of-the spark coil is periodically closed in proper synchronism with the engine, and included in this primary circuit or connected across the contact lever 25 and the contact cam 30 is the condenser 25 and vibrator mechanism 15 comprising vibrator blade 15 contact 15 and a magnetic core l5 which may form part of the spark coil 15. In this modified arrangement shown in Fig. 2, the closing of the circuit of the timer magnet coil 22 by shiftable adjustable movement for ark advance or retard is ef fected by coactiveengagementlof the contact post. or finger 53 with the yieldable contact .blades 69 and 70' which correspond in function to the yieldable fingers 69 and 70 described above. In this arrangement it is assumed that the distributer mechanism 18 or the distributer casing 36 is carried by or connected to the timer casmg 23. On account of the instantaneous formation of the or retarding the distributer,

degree of eontactual movement of the distributer arm 17 over each segment 19 of the distrlbuter being such as to complete (with.-

' out shiftable ad ustment of the distributer) at any pomt within the normal range of spark adjustment of the interrupter or timer, a spark plug circuit. In systems employing a vibrator primary circuit in which.

the spark is formed by closing the circuit,

- the incidental lag of the current and the necessity for extended contact dwell requires, in obtaining desired spark advanceand retard, simultaneous movement. of the timer or distributer mechanism through the whole angular range of adjustment. Therefore, it

will he seen that if in the use of the systemdisclosed in Fig. 2, it is desired to use a a timer or circuit controlling device, the movable contact or contacts of which are more directly carried by an inner adjustable shell, and in which the switch elements for establishing the shunt circuit of the magnet 22 are housed, the distributer casing 56 must beso mounted or connected to the inner casing or shell 54 of said previously described interrupter or timer construction or must be so otherwise connected as to be shiftably adjustable in unison with adjustablemovement of said inner shell or casing.

It will of course be. apparent that my invention is not limited to the employment of. directly connected interrupter ortimer and distributer mechanism. These elements may be separately formed and separately driven.- Furthermore, anism of the usual magneto generator may act in the capacity of distributer in the battery or continuous current ignition circuit. I have indicated such an arrangement in Fig. 3 which otherwise'discloses a system corresponding'with that illustrated in Fig. 1, and in which-like parts accordingly bear like reference numerals, so that it is unnecessary to here repeat'the description and operation otherwise than to disclose the feature of utilizing a common dis- .the interrupter casing 23, while to a movas disclosed above in con? transformer the angular .ticularly to Y the interrupter or the high tension win the distributer IIlQCh'.

Item and mechanism set 'forth in tributer element. As stat d, this :common distributerelement, shown'in Fig. 3, may

comprise the distributer 49' of a magneto generator 49.. It is well understood thatthis distributer of the magneto is operatively associated with the high tension winding of the magneto generator. I have indicated this high tension winding (not shown) as being connected, as by lead 71, to an insu lated switch contact or post 72, carried by I e able insulated switch member '73 I connect, as through lead 74;, the usual rotating arm or distributer element (not shown) of the magneto generator. The high tension winda iIig 16 of the battery circuit spark coil-or 30 145 connects with an insulated switch contact 7 5. Referring more par- Fig. 9, which illustrates in larger view the interrupter mechanism of the battery ignition circuit of Fig. 3, it will be seen that the movable switch element 73 is operatively carried by an oscillating or pivotal switch block 76 which'is adapted to be actuated by movement of the arm or armature 28 carried by the pivotal interrupter 0 contact mounting mechanism '7 6. This 1 movement in the particular construction, is efi'ected by means of a pinion 77 carried by the switch block 76 and which meshes with a short rack ortoothed foot 78 formed on the arm or armature 28. j The adjustment between the armature 28 andthe switch block 76 is such that when timer mechanism of the battery or continuous current ignition circuit is in operative condition, the high tension winding 16 of the spark coil 14 will be connected to the magneto distributer mechanism 49' via contacts and '73 and lead 7 4, and when the interrupter mechanism 0 the battery ignition circuit is inoperative, ding of the magneto generator connects with its own distributer mechanism 49'- via lead 71, switch. contacts 72 and 73 and lead 74. This is brought T about by the fact that movement of the armature 28, in either direction, whether by attraction ofthe interrupter or timer magnet 22 or by the returning action of the spring 31, alternately shifts the yieldable switch blade 73 into engagement with the switch posts or contacts 75 and 72 respectively.v I

From the foregoing description of the sysviews 1, 2 and 3, and as mentioned above, it will be readily seen that after the engine has been started and the switch arm 418 occupies anyposition of the switch arm 48, maintenance- -of closed circuit condition oi the winding grounded at 29 22 of the interrupter or timer mechanism obtains by reason of the fact that the mag netic cut out or relay of the main generator 2, remains closed during self-propulsion of the engine and generative driving of the generator 2. Dropping of the speed of the engine below self-propulsion or stopping thereof weakens'the magnetic attraction in the cut out core 7 so that a counter fiow of current from the battery 4 through the relay or cut out winding 9 neutralizes the magnetic attraction, to the pull of the spring 13, separating the contacts 10 and 11 and interrupting the circuit of the coil of the coil of the interrupter or timer mag- .net 22 which in turn causes the shiftable contact element of said mechanism to move to an inoperative position as already described. As a result,cthe spark coil 14 is brought out of connection with the battery, through breaking of the primary circuit upon contactual separation of the interrupter or timer arm or armature 28 or 28 and the core 21 of the magnet 22, the advantage of which is that the spark coil can not effect a dissipating pull on the battery when the engine is idle. This would be otherwise were all connections of the magnet Winding 22 established with the battery, through grounds 29 and 30 or in such other man ner,.,except as hereinafter set forth, as to preclude thecut-outwflect of the magnetic cut-out or relay operation of which is controlled or influenced by the generator 2, which, it will be presumed, is constantly driven when the engine -is in operation.

In the accomplishment of the above purpose means, as above described, are asso- I ciated with the magnet '22, for shifting the interrupter or timer contact levers or blades into an inoperative position. It will be apparent that I do not desire to limit my invention to the employment of such an arrangement. For instance in Fig. 10 I have indicated an ordinary form of interrupter mechanism comprising. a fixed insulated contact 243, a movable contact lever 25 and an actuating cam 30. I also show an electromagnet 22", the core 21 of which is included in the circuit of the primary winding 15 of the spark coil 14. The magnet 22 has a yieldable 'or spring blade armature 28 adapted to contact with a contact 28 which may form part of, or be electrically connected to, the fixed contact 24 The remaining parts of the system disclosed in this view,- Fig. 10, correspond in design and function to the system disclosed in Fig. 1" and above described and accordinglybear like reference numerals and need not be here described in repetition. It will be understood that when the winding 22 of the magnet 22 is energized, as by occupareleasing the armature 12 9 and therefore the circuit ment for cutting out the ence numerals.

-ing or coil lay of the 28 will be attracted by the resultantly'magnetized core 21 insuch manner as to contactwith the member 28 and bring contact mechanism 24 and 25 into operative circuit with the spark coil. This small magnet 22 may be placed at any suitable ,point inside or outside of the interrupter or timer, or distributer casin so long as the proper contact and terminal connections are afforded.

In Fig. 11 Ialso show a modified arrangespark coil when the engine stops. This may, as inthe present case, be accomplished without the employment of a separate magnet, and: without sacrificing the advantages of the switch and circuit arrangement, above described. The general system, including the contact mechanism in the battery circuit, corresponds with that. shown in Fig. 10 and like parts therefore in the present view bear like refer- When the switch arm 48 is shifted to S engine starting mechanism or its control, the

, movable contact 47, .by means of an extending finger 47 engages contact finger 38 in the circuit of the coil 15 and an extension 46 on the contact 46, bridges the two contacts 36 and 37 which are here shown as directly connected in the circuit of the wind- 15, and the contacts 24 and 25 completing the primary battery circuit. The battery therefore, through lead 50*,is brought into closed circuit with the engine starting mechanism and the primary winding of the spark coil. Release of the switch arm 48 causes the spring 51 to return the switch member41 or arm 48 to M position, resulting in disconnection of the engine starting mechanism or its control, in the manner above described, and also in interruption of the circuit of the primary winding 15 of the spark coil, by reason'of contact extension 46 finger 37. l .7

In this arrangement, it. will be seen that the winding 9 of the magnetic cut out or regenerator 2, is not brought into circuitwith the spark coil 14 when, in attraction of the armature 12 upon driving of the engine, the contact 11 engages contact 10 and connects the battery in charging circuit with the generator. However, I have provided switch or contact mechanism which is controlled by the core 7 of the relay. It

moving from contact position for connecting of the.

comprises, as clearly shown in Figs. 12

and 13, essentially an insulated contact blade 78 connected to the battery, as by lead 79, and constituting a yieldable armature arcontact 80 connected juxtaposition to a leg or ranged in suitable 7, anda relatively fixed face of the core move it into engagement with the contact 80 and bring into circuit with the battery, the primary winding 15 of the spark coil completion of the circuit of which with the battery would be efiected by movement of the switch arm 48 to either positions MB or B and resultant connection of contacts 36 and 37 by contact 46.

An advantage of the arrangement shown in Fig. 11 is that the battery primary ignition circuit, 'when otherwise completed in the manner already set forth, remains closed so long as the core 7 of the relay is energized sufficiently to. attractthe blade 8, and inasmuch as the relay winding is connected to the shunt winding 6 of the generator, the core of the relay remains active until the engine stops.

sired switch arrangement maybe used for making the various circuit connections outlined. The tacts for controlling the battery ignition current by adjustment may be such that the movable contact cated in Figs. 3 and 9 wherein the tacts are indicated at 69 and 70 fixed conwhile the movable contact constitutes an interme diateiy disposed yieldable blade 53*. It will also be apparent that the interrupter or ti'mer casing construction disclosed in Figs. 1 4:, 5 and 6 may be used without the emp oyment of a directly attached distributer mechanism. Such idea is shown in Figs. 3 and 9, the distributer of the battery ignition current being through the magneto generator distributer mechanism.
