Abstract
A fluid dispensing nozzle, e.g., a nozzle for a gasoline station filling pump, is provided with a trigger retaining mechanism which allows an operator to retain the nozzle trigger member in its operative position by exerting a continuous relatively low manual force in contrast to the relatively high manual force required to operate the trigger member. The trigger member automatically returns to its inoperative position immediately upon release of the manual force on the trigger retaining mechanism. The fluid dispensing nozzle is particularly suitable for use in self-service gasoline filling stations.
Claims10
In combination with a manually operable fluid dispensing nozzle including a valve to control the flow of fluid through the nozzle:
- a trigger member mounted on the nozzle for movement by a relatively high manual force between an inoperative position and an operative position to actuate the valve and control the fluid flow through the nozzle;
- and
- retaining means operable by a continuous relatively low manual force for holding said trigger member in its operative position and for automatically releasing said trigger member for return to its inoperative position upon termination of the relatively low manual force.
In combination with a manually operable gasoline dispensing nozzle including a valve to control the flow of gasoline through the nozzle:
- a manually operable trigger member pivotally mounted on the nozzle and normally biased to an inoperative position, said trigger member being movable by a relatively high manual force to an operative position to actuate the valve and control the flow of gasoline through the nozzle;
- and
- a manually operable trigger retaining mechanism mounted on the nozzle and operable by a continuous relatively low manual force for engaging said trigger member upon movement of said trigger member to its operative position to enable an operator to retain said trigger member in its operative position by continuous application of the relatively low manual force and for automatically releasing said trigger member for return to its inoperative position upon termination of the relatively low manual force.
A manually operable gasoline dispensing nozzle provided with a normally closed valve to control the flow of gasoline through the nozzle, including:
- a manually operable lever pivotally mounted on the nozzle for operating the valve, said lever being normally biased to an inoperative position and movable by a relatively high manual force to an operative position to open the valve and allow flow of gasoline through the nozzle;
- a first retaining member pivotally mounted on the nozzle for engaging said lever in its operative position;
- and
- a second retaining member mounted on the nozzle and manually operable by a relatively low manual force upon movement of said lever to its operative position for holding said first retaining member in engagement with said lever to prevent return movement of said lever to its inoperative position during continuous application of the relatively low manual force to said second retaining member.
A trigger mechanism for a manually operable gasoline dispensing nozzle including a normally closed valve provided with a displaceable actuator to control the flow of gasoline through the nozzle;
- comprising:
- an operating lever including a first end pivotally mounted on the nozzle adjacent to the valve actuator and a second, free end extending away from the valve actuator, said operating lever being normally biased to an inoperative position out of engagement with the valve actuator and movable by a relatively high manual force to an operative position into engagement with the valve actuator to open the valve and permit the flow of gasoline through the nozzle;
- an arm pivotally mounted on the nozzle and engageable with said free end of said operating lever upon movement of said operating lever to its operative position;
- and
- a manually operable retaining member being normally biased to a first position out of engagement with said arm and movable by a relatively low manual force to a second position in engagement with said arm to enable an operator to hold said arm in engagement with said free end of said operating lever to retain said operating lever in its operative position by continuous application of the relatively low manual force to said retaining member.
A trigger mechanism for a manually operable gasoline dispensing nozzle including a normally closed valve provided with a displaceable actuator to control the flow of gasoline through the nozzle, comprising:
- an operating lever including a first end pivotally mounted on the nozzle adjacent to the valve actutator and a second, free end extending away from the valve actuator, said operating lever being normally biased to an inoperative position out of engagement with the valve actuator and movable by a relatively high manual force to an operative position into engagement with the valve actuator to operate the valve and control the flow of gasoline through the nozzle;
- a plunger mechanism mounted on the nozzle adjacent to said free end of said operating lever and including a slidable plunger normally biased to a first position away from said free end of said lever and movable to a second position located in the path of movement of said free end of said operating lever;
- and
- a plunger actuating lever pivotally mounted on the nozzle and operable by a relatively low manual force for moving said plunger into the path of movement of said free end of said operating lever to enable an operator to retain said operating lever in its operative position by continuous application of the relatively low manual force to said plunger actuating lever.
