| Abstract: |
Nozzle arrangement which positively prevents the dispensing of unspecified fuels (e.g., leaded fuels) into "specification" automobiles which require "specification fuel" (e.g., non-leaded fuel) exclusively, while permitting the dispensing of unspecified fuels into other, "non-specification" automobiles. Separate pumping means are utilized for unspecified fuel and for specification fuel. The special fuel filler inlets of specification automobiles are modified (made special) to prevent use therein of a dispensing nozzle spout of standard configuration, a non-standard spout being employed for such automobiles. This non-standard spout incorporates an electrical lockout arrangement which functions to automatically render the unspecified-fuel pumping means inoperative whenever the non-standard spout is being utilized for dispensing into a special fuel filler inlet. Under other dispensing conditions, the unspecified-fuel pumping means is operative.

The invention claimed is:
1. In a motor fuel dispensing apparatus capable of dispensing specification fuel into the fuel tanks of specification automobiles requiring such fuel exclusively and having their fuel filler inlets constructed and arranged to prevent the insertion thereinto of dispensing nozzle spouts of standard configuration, said apparatus being also capable of a dispensing unspecified fuels into the fuel tanks of other, non-specification automobiles: a dispensing nozzle with a non-standard spout capable of insertion into the fuel filler inlets of both specification and non-specification automobiles, separate controllable means for pumping specification and unspecified fuels, respectively, through said nozzle spout, and means associated with said nozzle spout for causing the unspecified-fuel puming means to be rendered inoperative whenever said non-standard spout is inserted into the fuel filler inlet of a specification automobile.
