' recepite it is apparent that. ignition'is lproduced atf 52 only When-the timer contacts 29, `30 are closed. The higher the engine speed, thev shorter will be the timer contact closed periodi hence the shorter the duration ot the spark shower at 52. rThe inductance ot the coil 55 and -the reluctance of the magnetic circuit ot coil 55 is such' that at a predetermined.,

speed ot the timer 29, the contact closed period is so short that there will not be suthcient time tor the armature 6l to -be released trom the holding coil While it is shortcircuited.' Hence above a certain speed arma# ture Glwill remain in attracted position separating contacts 63, 64 astliougli the timer contacts 29, 30 were continuously open. rhis action tends to save battery current and to render the burner ignition in# operative when it may notbe necessaryto use the burner vWhen the engine has become warmed up 'and aas picked up iii speed. rllhe resistance ot ce 55 is high enough that the engine ignition will not be interfered with to any substantial degree.

Figs. 2 to 5 show an embodiment ofthe ignition device 40 in a unitary structure.

Housing tube rests on a base71 support-y ing coil 4i and core 42. -Core 42 includes a bundle ot` iron wires 72 and a center rod 7 3 engaging a nut 74 at its upper end and a nut 75 at its lower-end. Nut 74 bears Iagainst Washer 76 in turn bearing against wires 72 and a non-conducting sleeve k7 7 in turn bearingagainst an'end bell 4l ot coil 4l. By tightening nuts 74 and 75 the core and coil assembly issecured upon the base 7l. The yoke 53 is attached to end hell Lil and theI holding coil core projects through a hole 78 in non-magnetic vibrator base 79, this hole being lined with a non-conducting Washer 78a as shown-in Fig. 2. Thus core 54 is insulated electrically Jfrom the rest of the structure.v The hole 8.0 in base 79 is to permit the upper-end ot core a2 to extend ythrough it.v The base 79 supports the fulj crum post 49 which is attached thereto by tubular rivets Si and82 which are insulated from the base 79. `A bracket 83 riveted to base 79 supports the adjusting screw 65. The base 79 is provided With a recess in Which condenser G2 rests` this condenser being grounded on base 79 and secured thereto As shown in Fig. 4, the housing tube 70 supports the terminals 59. ,57 and designated by CB (mcaning-circuit breaker),

G (meaning ground) and B (meaning batt-erf), respectively., Terminal Gr is at` vtached to a metal clip which makes contact with the base 79 when securedv to tube70. v The base 79 supports a vibrator cover 91 Y attached thereto by 'anut 92 engaging ay post 93 extending through saidv cover 91 and at-v tached to the base 79.

YWhile the torni ot mechanism herein shown and described constitutes Aa preferred form of embodiment ot the invention, it is to be understood that other forms might be adopted, all coming Within the scope of the claims which follow.

What l claim is as follows: l. In an ignition system, thecombination with engine ignition' apparatus including a current source, ignit'ion'coil, an'y engine operated timer and an 'enginespark plug; of a vibrator ignition coil; an auxiliary spark plug connected to' said vibrator coil and means associated with said vibrator coil and controlled by said engine timer torpermitting` the vibrator coil to vbe operative only when the timer contacts are closed.

2. In an ignition system,-.the combination with engine Vignition apparatus including a current source, ignition coil, anengine operated timer and. an engine spark plug; ot a vibrator ignition coil including a core andvibrating armature; an auxiliary spark plug connected to said vibrator coil; and an auxiliary electromagnet associated with v said armature and connected i n-shunt with saidtiiner contacts for preventing operation ot said armature when said timer contacts are opened. Y y

Inan ignition system, the combination with engine ignition apparatus including a current source, ignition coil.`an engine operated timer and an engine spark pliw; of a vibrator coil including a core and vibrating armature; an,` auxiliary spark plug connected to said vibrator coil; and an auxiliary magnet having a core in magnetic circuit with said vibrator vcoil core and .armature and a Winding` in shunt with the timer contacts. i f f v- 4. ln a device of the character described,

'the' combination Wit-h a housing having a removable closing member provided with openingss; an ignition coil having a core located Within said housing. and a control y ling coil having a core located Within said housing, both ot said cores proyecting through openings in said closing member; a

ing member in proximity to said cores; a

lvibrating armature supported by said closcontact supported by said armature; and a contact supported by closing member.
