all whom it may concern:

Be it known that WILLIAM K. BAssroRD,

invented vcert-ain new and useful improve ments in lgniters for Engines, of which the following is a specification. l

, invention relates generally to means igniting internal combustion engine fuel, e id specifically to an improved device for automatically advancing and retarding the .ligniting electric spark.

The-gener' "object of my invention is to `prevent;accidents' to the operator, while the set fort-h as follows:- i, a generator armature rospeciic ect As well.- kno tati-ng in-.fafmagiietic eld of force has a certain point of maximum voltage.

Heretofore, the timing of the' spark has been so arranged that the spark will occur at the point of maximum voltage, which point is shifted by manual means forward or backward.

However, as the control is by hand, it may l 4easily bevperceived that. when ,the spark is at L. rIwo swinging weights dvanced ,*.t hen, unless the point of maxiigum voltagepf the armature isalsoadl iroughthe same number of degrees,the` des. d benefit 1s lost for the reasonthat thes'spark is not ofthe same intensity..A- As inaiageinent by hand is unsatisfactory and dangerous, l have invented means for accomplishing the adjustment-s by the action of the rotating armature. i gain the result that however farl the timing device is advanced, the armature isadvanced angularly, through the saine number of degrees simultaneously, and the spark will always occur at the point of maximum voltao'e.

'Figure l is an end view of the complete invention. Much of the `frame work and casing and unnecessary elements for exhibiting the invention, are omitted. ifotted lines show hidden parts. Fig. @is the rear of the lower part of Fig. l. Fig. 3 is a side view of the invention. l? ig. 4 shows a detail, with parts in section. Fig. is a face view the Contact plate.

rlhe arms l? and p radiate oppositely from a disk T, and are for the purpose of b moved to change the angular posit armature with respect to the shaft electric spark generator whose armat ilxed to gear wheels R and R1, the arbors for the wheels being carried by the disk T. A gear on the armature sleeve L1 meshes `with the gear wheels R and R1, the weights flying outward by the action of centrifugal force. is the disk T is fastened rigidly to the shaft M, as the armature L is on the sleeve L1, which is loose on the shaft M, and

as there is a spring S1 connecting the arm P to the weight P1, and a spring S2 connecting the arm p to the weight P2, therefore, the higher the rotary speed of the armature the greater the outward movements of the weights P1 and P2, and the greater the angular advancement ofthe arinz'iture. V is another gear wheel fixed on the armature sleeve L1 and meshing with the gear wheel H on which is mounted a timing device. the centrifugal force, according to the speed, changes the angular position of the armature L and sleeve L1, it also changes the angular position of the gear V, and therefore accomplishes the adjustment of the timing device with relation to the shaft M and the engine, as well as the adjustment of the armature to the point of maximum voltage.

rfhe timing device consists of the roller 2 rotating at the end of a lever J which is pivoted to lugs 3 eccentrically located on the wheel H.

' el, e2, c3, e", are contacts arranged in a row around the axis of thewheel H and in the path of the roller so that as the latter rotates, it wilt touchthese four contacts.

5 is a spring for pressing the roller 2 against the contacts.

Other parts shown in the drawing have nothing to do with the invention, vwhich is however defined as to its scope of novelty in the accompanying claim.

i claim as my invention;

ln an ignit 1r for internal. combustion engines, the combination of af' sleeve, an armature xed thereon, a driving shaft for the armature passing loosely through said. sleeve, a governor mounted upon said shaft, and gearing between said sleeve and governor for permitting the relation between said armature and driving shaft to be changed.
