Abstract
Abstract Engine timing fluctuations and intermittent loss of synchronization between the distributor and the timing gear are eliminated by this distributor drive system in which the distributor is mounted on a timing gear cover at the front of the engine. The distributor is driven from the timing gear via a drive disc and an adaptor shaft that are relatively axially moveable so as to isolate the distributor from axial cam shaft movement.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
219 words
A system for driving the distributor of an engine from the front thereof, comprising: a drive disc adapted to be concentrically affixed to the front face of the timing gear of said engine, said drive disc having a central, geometrically shaped bore therein, a cover adapted to be attached to the front of said engine, said cover having an integral mounting platform for said distributor, together with a cylindrical bore extending to said platform, a drive rod for said distributor journaled within said mounting platform bore, a gear set mounted within said cover and including one gear member affixed to said drive rod and a cooperating gear mounted for coaxial alignment with said timing gear and drive disc, and an adaptor shaft coaxially attached to said cooperating gear, said shaft having a correspondingly geometrically shaped projection adapted for mating insertion into said drive disc bore so that rotation of said timing gear and drive disc will rotationally drive said distributor via said adaptor shaft, said gear set and said distributor drive rod, said shaped projection being axially unattached to said drive disc so as to permit relative axial movement therebetween, whereby said timing disc and distributor will be driven in synchronism regardless of axial displacement or twisting of the engine cam shaft to which said timing gear is attached.
Claim 2
Independent Claim
219 words
A system for driving the distributor of an engine from the front thereof, comprising: a drive disc adapted to be concentrically affixed to the front face of the timing gear of said engine, said drive disc having a central, geometrically shaped bore therein, a cover adapted to be attached to the front of said engine, said cover having an integral mounting platform for said distributor, together with a cylindrical bore extending to said platform, a drive rod for said distributor journaled within said mounting platform bore, a gear set mounted within said cover and including one gear member affixed to said drive rod and a cooperating gear mounted for coaxial alignment with said timing gear and drive disc, and an adaptor shaft coaxially attached to said cooperating gear, said shaft having a correspondingly geometrically shaped projection adapted for mating insertion into said drive disc bore so that rotation of said timing gear and drive disc will rotationally drive said distributor via said adaptor shaft, said gear set and said distributor drive rod, said shaped projection being axially unattached to said drive disc so as to permit relative axial movement therebetween, whereby said timing disc and distributor will be driven in synchronism regardless of axial displacement or twisting of the engine cam shaft to which said timing gear is attached.
Claim 3
Dependent Claim
77 words
A distributor drive system according to claim 1 wherein said mounting platform comprises a generally hemicylindrical section projecting vertically upwardly from said timing cover, said cover including a bearing receiving cylindrical boss coaxially aligned with said timing gear, said cooperating gear being bearing mounted within said boss, said mounting platform boss extending through said vertically projecting section and opening into said cylindrical boss so that said one gear member and said cooperating gear mesh in said opening.
