Device for modifying spark ignition in carburetor engines into torch ignition

Claim 1

THE COMBINATION WITH AN INTERNAL COMBUSTION ENGINE HAVING A HEAD, CYLINDERS IN THE HEAD, A FUEL PUMP, CARBURETOR, A FULE SOURCE, AND CONDUIT MEANS LEADING FROM THE FUEL SOURCE TO THE FUEL PUMP AND ACRBURETOR, OF AN ASSEMBLAGE FOR MODIFYING SPARK IGNITION INTO TORCH IGNITION FOR SUCH EINGINE, SAID ASSEMBLAGE INCLUDING AN AUXILIARY CARBURETOR, ADDITIONAL CONDUIT MEANS OPERABLY CONNECTED WITH THE FUEL PUMP AND THE AUXILIARY CARBURETOR FOR SUPPLYING THE AUXILIARY CARBURETOR WITH FUEL, THE HEAD HAVING A WELL ABOVE EACH CYLINDER AND IN COMMUNICATION THEREWITH, MEANS CONSTITUTING A PRECOMBUSTION CHAMBER ADAPTED WITH, MEANS CONSTITUTING A PRECOMBUSTION CHAMBER ADAPTED TO BE DETACHABLY MOUNTED IN EACH WELL, EACH PRECOMPRECOMBUSTION SPACE IN THE BODY AND ORIFICES THEREIN FOR ESTABLISHING COMMUNICATION BETWEEN THE PRECOMBUSTION SPACE AND THE CYLINDER, A SPARK PLUG DIRECTLY POSITIONED IN THE PRECOMBUSTION SPACE, FURTHER CONDUIT MEANS BETWEEN THE AUXILIARY CARBURETOR AND EACH PRECOMBUSTION CHAMBER FOR SUPPLYING A MIXTURE OF LIGHT FUEL FRACTIONS AND AIR FROM SUCH CARBURETOR TO EACH CHAMBER, AND AUTOMATICALLY OPERABLE VALVE MEANS IN THE BODY FOR CONTROLLING THE SUPPLY OF SUCH MIXTURE THROUGH SAID FURTHER CONDUIT MEANS TO THE PRECOMBUSION SPACE WITH SUCH VALE MEANS OPENING DURING THE ADMISSION STROKE FOR CREATING A VACUUM WITHIN THE AUXILIARY CARBURETOR TO DRAW AIR INTO SUCH CARBURETOR FOR MIXING WITH THE FUEL SUPPLIED TO THE AUXILIARY CARBURETOR BY THE FUEL PUMP WHILE THE VALVE CLOSES AT THE BEGINNING OF THE COMPRESSION STROKE SO THAT THE PRECOMBUSTION SPACE FILLED WITH THE MIXTURE FROM THE AUXILIARY CARBURECTOR RECEIVES THE MIXTURE FROM THE ASSOCIATED CYLINDER VIA THE ORIFICES AND WHEN THE MIXTURE IN THE PRECOMBUSTION SPACE IS IGNITED BY THE ACTIVATION OF THE SPARK PLUG, THE TORCH FLAME ENTERS THE CYLINDER AND IGNITES THE MIXTURE THEREIN.
