Abstract
Abstract A fuel supplying apparatus comprises a flowmeter and a reversible plate type flow indicator. The reversible plate type flow indicator includes shift means of a decimal system actuated in a mechanical manner and resetting means for zero-resetting the indication. This reversible plate type flow indicator is preferably provided in a stationary stand post secured to an island in a servicing area of a fuel supplying station.

Total Claims: 7
Claim 1
Independent Claim
338 words
A fuel supplying apparatus having a reversible plate type flow indicator comprising: a fuel reservoir for storing fuel; a stand post outer shell secured at a suitable place on the ground in a servicing area of a fuel supplying station; a delivery hose extending through said outer shell and having a delivery nozzle attached to the foremost end thereof; pump means for delivering the fuel from said reservoir to said delivery hose through a pipe extending through said outer shell and opening at one end thereof into said reservoir; a flowmeter for measuring the flow quantity of the fuel delivered through said pipe and thereby to produce a rotation output in accordance with the measurement; flow quantity indication means including a reversible plate type indicating element which comprises a plurality of rotary elements corresponding in number to the number of digits to be indicated and ten reversible plates for indicating figures reversibly mounted on each of said rotary elements; a rotation transmission mechanism for transmitting in a mechanical manner the rotation output of said flowmeter to one of said reversible plate type indicating elements of said flow quantity indication means which represents the lowest order digit; and zero-resetting means for rotating the indicating element for each digit in a predetermined direction so as to reset all figures on the reversible plate indicating the flow quantity to zero, said flow quantity indication means having shift means for effecting shifting based on a decimal scale of notation from a reversible plate type indicating element representing a lower order digit to that representing a higher order digit, each of said reversible plate being constructed so that either one of figures ''''0'''' through ''''9'''' may be indicated by combination of a reversible plate preceding in the direction of rotation which has been reversed and an immediately following reversible plate which has not been reversed yet and the reversible plates of the reversible plate type indicating element for respective digits as a whole indicating the flow quantity of fuel measured by said flowmeter.

A fuel supplying apparatus having a reversible plate type flow indicator comprising: a fuel reservoir for storing fuel; a stand post outer shell secured at a suitable place on the ground in a servicing area of a fuel supplying station; a delivery hose extending through said outer shell and having a delivery nozzle attached to the foremost end thereof; pump means for delivering the fuel from said reservoir to said delivery hose through a pipe extending through said outer shell and opening at one end thereof into said reservoir; a flowmeter for measuring the flow quantity of the fuel delivered through said pipe and thereby to produce a rotation output in accordance with the measurement; flow quantity indication means including a reversible plate type indicating element which comprises a plurality of rotary elements corresponding in number to the number of digits to be indicated and ten reversible plates for indicating figures reversibly mounted on each of said rotary elements; a rotation transmission mechanism for transmitting in a mechanical manner the rotation output of said flowmeter to one of said reversible plate type indicating elements of said flow quantity indication means which represents the lowest order digit; and zero-resetting means for rotating the indicating element for each digit in a predetermined direction so as to reset all figures on the reversible plate indicating the flow quantity to zero, said flow quantity indication means having shift means for effecting shifting based on a decimal scale of notation from a reversible plate type indicating element representing a lower order digit to that representing a higher order digit, each of said reversible plate being constructed so that either one of figures ''''0'''' through ''''9'''' may be indicated by combination of a reversible plate preceding in the direction of rotation which has been reversed and an immediately following reversible plate which has not been reversed yet and the reversible plates of the reversible plate type indicating element for respective digits as a whole indicating the flow quantity of fuel measured by said flowmeter.
Claim 3
Dependent Claim
173 words
A fuel supplying apparatus as defined in claim 1 in which said shift means comprise a wheel with a reduced number of teeth provided on the rotary element of said indicating element represeting a lower order digit, a wheel provided on the rotary element of said indicating element representing a higher order digit and interlocking means provided between said wheel provided on the rotary element representing a lower order digit and said wheel provided on the rotary element representing a higher order digit for intermittently rotating by a predetermined angle said latter mentioned wheel together with said rotary element representing a higher order digit at Each one rotation of said wheel provided on the rotary element of a lower order digit, said rotary element representing a higher order digit being rotated by a predetermined angle through said shift means at each one rotation of said rotary element representing a lower order digit whereby the figure indicated on said indicating element representing a higher order digit is shifted by one in a forward direction.
Claim 4
Dependent Claim
101 words
A fuel supplying apparatus as defined in claim 1 in which said zero-resetting means comprise a V-shaped groove formed axially in a shaft member which rotatably supports said rotary element and a pawl member which is provided on each of said rotary element and is brought into engagement with said V-shaped groove by rotation of said shaft member in the same direction as the forward rotation of said rotary element, the resetting being made by a mechanical operation to bring said pawl member into positive engagement with said V-shaped groove thereby to rotate said rotary member integrally with said shaft member.
Claim 5
Dependent Claim
193 words
A fuel supplying apparatus as defined in claim 3 in which said shift means comprise a wheel with a reduced number of teeth provided on the rotary element of the indicating element representing a lower order digit, a wheel provided on the rotary element of the indicating element representing a higher order digit and an interlocking means provided between said wheel with a reduced number of teeth and said wheel provided on the rotary element of the indicating element representing a higher order digit for intermittently rotating said latter wheel together with said rotary element of the indicating element representing a higher order digit by a predetermined angle at each one rotation of said wheel with a reduced number of teeth, a ratched wheel fixedly secured to said latter wheel and rotatable relative to said rotary element and locking means mounted on said rotary element for locking said ratchet wheel and releasing same during the forward rotation of said rotary element and said shift means are maintained in a non-operative state by disengagement of said ratchet wheel from said locking means during the forward rotation of said rotary element in the zero-resetting operation.
Claim 6
Dependent Claim
80 words
A fuel supplying apparatus as defined in claim 1 in which said reversible plate type indicating element further comprises first stopper means for stopping a preceding reversible plate and second stopper means for stopping an immediately following reversible plate, said first and second stopper means being so constructed that release of said preceding reversible plate from said first stopper means precedes release of said following reversible plate from said second stopper means during the forward rotation of said rotary element.
Claim 7
Dependent Claim
76 words
A fuel supplying apparatus as defined in claim 1 in which said reversible plate type flow indicator further comprises an index ring representing the lowest order digit, said index ring being marked with figures ''''0'''' through ''''9'''' on the periphery thereof and being continuously rotated upon application thereto of the rotational force from the flowmeter thereby to rotate intermittently an indicating element of a reversible plate type representing a higher order digit through said shift means.
