Abstract
An ignition distributor where the rotor of the distributor is driven by the camshaft of an internal combustion engine. The end of the camshaft has an axially extending bore. The ignition distributor has a coupling. The coupling has an axially extending shaft portion that is located in the bore of the camshaft. The coupling has a laterally extending portion that has a radially extending slot. The camshaft carries a drive pin. One end of the drive pin is located in the slot with the pin engaging internal side wall surfaces of the slot. The pin forms a drive means for driving the coupling from the camshaft. The coupling drives the rotor of the distributor.
Claims4
A drive for driving the rotor of an ignition distributor from the camshaft of an internal combustion engine, comprising in combination, an engine camshaft, said camshaft having an axially extending bore, an ignition distributor having a base, said ignition distributor having a coupling that is rotatably supported by said base, said coupling having an axially extending shaft portion that is located in said bore, said coupling having a radially extending slot defined by opposed radially extending side surfaces, a drive pin secured to said camshaft, said pin having a portion located in said slot with said pin engaging said side surfaces of said slot, and a rotor for said distributor driven by said coupling.
An ignition distributor having a rotor that is adapted to be driven by the camshaft of an internal combustion engine comprising, a base, a coupling rotatably supported by said base, said coupling having a laterally extending portion and an integral shaft portion that extends axially from said laterally extending portion, said shaft portion being adapted to be inserted into a bore formed in the camshaft of an internal combustion engine when said distributor is assembled to an engine, said laterally extending portion having a radially extending slot defined by spaced radially extending surfaces, said surfaces being adapted to engage a drive pin secured to said camshaft.
