Abstract
Spark distribution method and means of the variable magnetic flux type for nternal combustion engines comprising respective cooperative steps and parts in and for a spark distributor including: a spark shaft inside a housing with a gear on the shaft that is driven thereby and rotatably movable with the shaft by means of at least one integral advance wheel or element that may be of a centrifugal design and which is displaced towards a magnetic flux "captor" element which channels magnet flux towards the shaft, there being in the wall of the housing opposite the advance device a slot roughly perpendicular to the shaft and a corresponding orifice in said advance device which is opposite the slot so that the optimum static adjustment of the spark point being conducted may be accomplished by first positioning the gear with respect to the captor and then setting the distributor from without the housing to a calibrated mark on the external surface of the housing with matched placement therewith of the head of a setting device which passes through the slot to be fixed at its inner end in said orifice and which has a fragile break area disposed inside the housing allowing its outwardly exte…
