Internal combustion engine ignition systems

Claim 2

An internal combustion engine ignition distributor assembly, comprising a drive gear member with a dished hub portion adapted to be secured coaxially on one end of an internal combustion engine camshaft; a carrier member secured coaxially within a rim portion of said drive gear member so as to overlie said dished hub portion and form therewith a hollow chamber, said carrier member having a central opening therein; an ignition distributor housing journaled in said opening; a distributor main shaft journaled in said housing, one end of the main shaft within said housing having thereon cam surfaces to operate an ignition interrupter mechanism arranged within said housing, and said one end of the main shaft carrying a distributor rotor, the other end of said main shaft extending into said chamber and carrying a centrifugal ignition timing control mechanism which is freely rotatable in said chamber; said timing control mechanism having a pair of resiliently interconnected but relatively rotatable members, one of which is secured to said main shaft and the other of which is arranged for rotation with said drive gear member; and a steady plate secured to said housing adapted to be anchored to a fixed part of the engine to secure the housing against rotation.

Claim 3

In a reciprocatory internal combustion engine with a rotary camshaft; a drive gear member secured coaxially on one end of said camshaft, said drive gear member having a dished hub portion; a carrier member secured coaxially within a rim portion of said drive gear member so as to overlie said dished hub portion and form therewith a hollow chamber, said carrier member having a central oPening therein; an ignition distributor housing journaled in said opening; a distributor main shaft journaled in said housing, one end of the main shaft within said housing having thereon cam surfaces to operate an ignition interrupter mechanism arranged within said housing, and said one end of the main shaft carrying a distributor rotor; the other end of said main shaft extending into said chamber and carrying a centrifugal ignition timing control mechanism which is freely rotatable in said chamber, said timing control mechanism having a pair of resiliently interconnected but relatively rotatable members, one of which is secured to said main shaft and the other of which is drivingly connected with said drive gear member and camshaft for rotation thereby and in synchronism therewith; a steady plate secured to said housing adapted to be anchored to a fixed part of the engine to secure the housing against rotation; and a flexible drive coupling between said drive gear member and the crankshaft of said engine.

Claim 4

In a reciprocatory internal combustion engine with a rotary camshaft; a drive gear member secured coaxially on one end of said camshaft, said drive gear member having a dished hub portion; a carrier member secured coaxially within a rim portion of said drive gear member so as to overlie said dished hub portion and form therewith a hollow chamber, said carrier member having a central oPening therein; an ignition distributor housing journaled in said opening; a distributor main shaft journaled in said housing, one end of the main shaft within said housing having thereon cam surfaces to operate an ignition interrupter mechanism arranged within said housing, and said one end of the main shaft carrying a distributor rotor; the other end of said main shaft extending into said chamber and carrying a centrifugal ignition timing control mechanism which is freely rotatable in said chamber, said timing control mechanism having a pair of resiliently interconnected but relatively rotatable members, one of which is secured to said main shaft and the other of which is drivingly connected with said drive gear member and camshaft for rotation thereby and in synchronism therewith; a steady plate secured to said housing adapted to be anchored to a fixed part of the engine to secure the housing against rotation; and a flexible drive coupling between said drive gear member and the crankshaft of said engine.

Claim 5

In a reciprocatory internal combustion engine, a rotary camshaft; a drive gear member with a recessed hub portion fixed on said camshaft; a flexible drive belt member which drivingly couples said drive gear member to a gear driven by the engine crankshaft; a carrier member fixed on said drive gear member, said carrier member having a central opening therein; an ignition distributor housing rotatably journaled in said housing; a distributor main shaft journaled in said housing and having a coaxial driving connection with said drive gear member and said camshaft, said housing being secured against rotation about the camshaft axis and said carrier member being secured within the rim portion of said drive gear member so as to overlie said recessed hub portion and form therewith a hollow chamber; and a centrifugal ignition timing control mechanism carried on said main shaft and rotatable within said chamber.

Claim 6

In a reciprocatory internal combustion engine, a rotary camshaft; a drive gear member with a recessed hub portion fixed on said camshaft; a flexible drive belt member which drivingly couples said drive gear member to a gear driven by the engine crankshaft; a carrier member fixed on said drive gear member, said carrier member having a central opening therein; an ignition distributor housing rotatably journaled in said housing; a distributor main shaft journaled in said housing and having a coaxial driving connection with said drive gear member and said camshaft, said housing being secured against rotation about the camshaft axis and said carrier member being secured within the rim portion of said drive gear member so as to overlie said recessed hub portion and form therewith a hollow chamber; and a centrifugal ignition timing control mechanism carried on said main shaft and rotatable within said chamber.
