Apparatus for supplying an air/fuel mixture from a carburetor system to an internal combustion engine

Claim 1

AN APPARATUS FOR SUPPLYING AN AIR/FUEL MIXTURE FROM A CARBURETOR SYSTEM TO AN INTERNAL COMBUSTION ENGINE, SAID APPARATUS COMPRISING A PRIMARY CONDUIT SYSTEM AND A SECONDARY CONDUIT SYSTEM, SAID SECONDARY CONDUIT SYSTEM ADAPTED TO CONNECT THE CARBURETOR SYSTEM TO THE ENGINE, SAID PRIMARY SYSTEM BRANCHING OFF FROM AND RETURNING TO SAID SECONDARY SYSTEM, HEATING MEANS IN SAID PRIMARY CONDUIT SYSTEM FOR HEATING THE AIR/FUEL MIXTURE PASSING THERETHROUGH, SAID SECONDARY CONDUIT SYSTEM HAVING A GREATER CROSS-SECTIONAL AREA THAN SAID PRIMARY CONDUIT SYSTEM, A FIRST THROTTLE MEANS DISPOSED IN ONE OF SAID CONDUIT SYSTEMS TO CONTROL THE FLOW OF AIR/FUEL MIXTURE THROUGH SAID PRIMARY CONDUIT SYSTEM, A SECOND THROTTLE MEANS DISPOSED IN SAID SECONDARY CONDUIT SYSTEM BETWEEN THE POINTS AT WHICH SAID PRIMARY CONDUIT SYSTEM BRANCHES FROM AND RETURNS TO SAID SECONDARY CONDUIT SYSTEM TO CONTROL THE FLOW OF AIR/FUEL MIXTURE THROUGH SAID SECONDARY CONDUIT SYSTEM A CONTROL MEMBER MOVABLE FROM AN IDLING POSITION TO A FULL THROTTLE POSITION, MEANS DIRECTLY OPERATIVELY CONNECTING SAID CONTROL MEMEBER TO SAID THROTTLE MEANS TO PROVIDE MOVEMENT OF SAID FIRST THROTTLE MEANS FROM A CLOSED TO AN OPEN POSITION IN RESPONSE TO MOVEMENT OF SAID CONTROL MEANS FROM SAID IDLING POSITION TO SAID FULL THROTTLE POSITION, A LOST-MOTION CONNECTING MEANS OPERATIVELY CONNECTING SAID FIRST THROTTLE MEANS AND SAID SECOND THROTTLE MEANS UPON SAID FIRST THROTTLE MEANS ATTAINING A PREDETERMINED POSITIONED BETWEEN SAID CLOSED AND SAID OPEN POSITION, SO THAT SAID SECOND THROTTLE MEANS IS OPEN DURING MOVEMENT OF SAID FIRST THROTTLE MEANS FROM SAID PREDETERMINED POSITIONED TO SAID OPEN POSITION, AND RESILIENT MEANS CONNECTED TO SAID LOST-MOTION CONNECTION MEANS AND NORMALLY URGING SAME TO A CLOSED POSITION DURING MOVEMENT OF SAID FIRST THROTTLE MEANS FROM SAID CLOSED TO SAID PREDETERMINED POSITION.

Claim 2

AN APPARATUS FOR SUPPLYING AN AIR/FUEL MIXTURE FROM A CARBURETOR SYSTEM TO AN INTERNAL COMBUSTION ENGINE, SAID APPARATUS COMPRISING A PRIMARY CONDUIT SYSTEM AND A SECONDARY CONDUIT SYSTEM, SAID SECONDARY CONDUIT SYSTEM ADAPTED TO CONNECT THE CARBURETOR SYSTEM TO THE ENGINE, SAID PRIMARY SYSTEM BRANCHING OFF FROM AND RETURNING TO SAID SECONDARY SYSTEM, HEATING MEANS IN SAID PRIMARY CONDUIT SYSTEM FOR HEATING THE AIR/FUEL MIXTURE PASSING THERETHROUGH, SAID SECONDARY CONDUIT SYSTEM HAVING A GREATER CROSS-SECTIONAL AREA THAN SAID PRIMARY CONDUIT SYSTEM, A FIRST THROTTLE MEANS DISPOSED IN ONE OF SAID CONDUIT SYSTEMS TO CONTROL THE FLOW OF AIR/FUEL MIXTURE THROUGH SAID PRIMARY CONDUIT SYSTEM, A SECOND THROTTLE MEANS DISPOSED IN SAID SECONDARY CONDUIT SYSTEM BETWEEN THE POINTS AT WHICH SAID PRIMARY CONDUIT SYSTEM BRANCHES FROM AND RETURNS TO SAID SECONDARY CONDUIT SYSTEM TO CONTROL THE FLOW OF AIR/FUEL MIXTURE THROUGH SAID SECONDARY CONDUIT SYSTEM A CONTROL MEMBER MOVABLE FROM AN IDLING POSITION TO A FULL THROTTLE POSITION, MEANS DIRECTLY OPERATIVELY CONNECTING SAID CONTROL MEMEBER TO SAID THROTTLE MEANS TO PROVIDE MOVEMENT OF SAID FIRST THROTTLE MEANS FROM A CLOSED TO AN OPEN POSITION IN RESPONSE TO MOVEMENT OF SAID CONTROL MEANS FROM SAID IDLING POSITION TO SAID FULL THROTTLE POSITION, A LOST-MOTION CONNECTING MEANS OPERATIVELY CONNECTING SAID FIRST THROTTLE MEANS AND SAID SECOND THROTTLE MEANS UPON SAID FIRST THROTTLE MEANS ATTAINING A PREDETERMINED POSITIONED BETWEEN SAID CLOSED AND SAID OPEN POSITION, SO THAT SAID SECOND THROTTLE MEANS IS OPEN DURING MOVEMENT OF SAID FIRST THROTTLE MEANS FROM SAID PREDETERMINED POSITIONED TO SAID OPEN POSITION, AND RESILIENT MEANS CONNECTED TO SAID LOST-MOTION CONNECTION MEANS AND NORMALLY URGING SAME TO A CLOSED POSITION DURING MOVEMENT OF SAID FIRST THROTTLE MEANS FROM SAID CLOSED TO SAID PREDETERMINED POSITION.
