Abstract

A method of assembling an ignition distributor including the steps of engaging an annular timing plate with an annular base plate so that the timing plate is capable of angular movement with respect to the base plate. Three ears formed on the base plate overlie the timing plate, and the timing plate is rotated relative to the base plate, so that three ramps provided on the timing plate engage the ears respectively. As the timing plate is rotated the ramps bend the ears away from the timing plate, so that a clearance exists between the ears and the timing plate which is substantially equal to the heights of the highest part of the ramps above the surface of the timing plate. Thus the timing plate will be capable of a predetermined degree of axial movement relative to the base plate.

Claims (4)

1. A method of assembling an ignition distributor of the kind specified including the steps of: engaging an annular timing plate with an annular base plate so that mating surfaces on the two plates locate the timing plate for angular movement on the base plate; deforming three ears provided on a first plate of the pair of plates constituted by the timing plate and the base plate, towards the surface of the second plate remote from the first plate, said ears being provided on the first plate in such a manner that any one of the ears is on the opposite side of a diameter of the first plate from the remaining ears; and moving the first plate angularly relative to the second plate so that three ramps upstanding from the second plate engage the ears respectively and deform the ears away from said surface of the second plate, so that a predetermined clearance substantially equal to the heights of the highest parts of the ramps above said surface of the second plate, exists between the second plate, said predetermined clearance thereby rendering the first and second plates capable of relative axial movement through a predetermined distance.
2. A method of assembling an ignition distributor of the kind specified including the steps of: engaging an annular timing plate with an annular base plate so that mating surfaces on the two plates locate the timing plate for angular movement on the base plate, and three ears formed on a first plate of the pair of plates constituted by the base plate and the timing plate overlie the surface of the second plate remote from the first plate, the ears being disposed on the first plate in such a manner that anyone of the ears is on the opposite side of a diameter of the first plate from the remaining ears; and moving the first plate angularly relative to the second plate so that three ramps upstanding from the second plate engage the ears respectively and deform the ears away from said surface of the second plate, so that a predetermined clearance substantially equal to the heights of the highest parts of the ramps above said surface of the second plate, exists between the second plate, said predetermined clearance thereby rendering the first and second plates capable of relative axial movement through a predetermined distance.
3. A method as claimed in claim 1 wherein said step of engaging the timing plate with said base plate includes mounting said annular base plate for rotation upon a concentric cylindrical spigot formed in the base plate.
4. A method as claimed in claim 2 wherein said step of engaging the timing plate with said base plate includes mounting said annular base plate for rotation upon a concentric cylindrical spigot formed in the base plate.
