Abstract

Abstract A dispensing nozzle for delivering fuel to selective fuel tanks has a control rod which must be displaced longitudinally by a restrictor plate in the fill tube of the fuel tank before the manual lever of the dispensing nozzle is effective to open the flow controlling valve of the dispensing nozzle. Thus, the introduction of one grade of fuel into a tank not having a restrictor plate and requiring a different grade of fuel is prevented.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 232 words
A fuel dispensing nozzle for dispensing fuel into a fuel tank having a fill tube and a restrictor plate secured in said fill tube and having an aperture slightly larger than said nozzle, said dispensing nozzle comprising; a handle, a lever and a valve mechanism for controlling fuel dispensing; a fuel delivery tube extending from said handle; a fulcrum slidably mounted in said handle and pivotally connecting said lever to said handle and being movable by said lever between an operative position wherein said lever will operate said valve and an inoperative position wherein said lever will not operate said valve; a control aperture in said fulcrum; and a fulcrum control mechanism comprising a support secured to said fuel delivery tube; a control rod having one end slidably mounted in said support and the other end slidably mounted in said handle adjacent the control aperture in said fulcrum, and spring means urging said rod toward said support and removed from said control aperture so that said fulcrum is free to move to said inoperative position, said control rod being movable by abutment with said restrictor plate when said fuel delivery tube is inserted through said aperture, said movement being sufficient to engage said control rod in said control aperture so that said fulcrum will be held in said operative position whereby said valve mechanism can be operated by movement of said lever.
Claim 2
Dependent Claim 232 words
