IGNITION DISTRIBUTORS

A method of assembling an ignition distributor of the kind which includes a base plate which is secured to the casing of the distributor and a timing plate which is mounted for angular movement on the base plate includes the steps of engaging a first annular plate with an annular base plate so that three projections provided on the first plate extend through corresponding apertures in the base plate. The three projections of the first plate are so disposed that any one of the projections is on the opposite side of a diameter of the first plate from the remaining projections. The portions of the projections which extend from the base plate are then subject to a levelling operation so that the free ends of the projections lie in a common plane parallel to, but above the plane of the base plate. A third annular plate is then engaged with the free ends of the projections where they extend from the base plate, and resilient means is utilized to couple the first plate and the third plate to define an assembly. The resilient means urges the third plate towards the first plate, and the first or third plate includes a cylindrical spigot which extends through a hole in the base plate, so that the assembly of the first and third plates is movable angularly relative to the base plate. Either the first plate, or the third plate constitutes the timing plate of the distributor in use, and carries the contact breaker assembly of the distributor.
