Abstract
Abstract An inlet insert to be positioned within the fuel tank inlet pipe of an automotive vehicle to prevent filling the tank with improper fuels. The insert permits full insertion of and delivery from a pump nozzle spout of a predetermined diameter or less, to be used with non-leaded fuels, and precludes full insertion of and delivery from a larger diameter pump nozzle spout, to be used with leaded fuels. The insert includes abutment means constructed to withhold the delivery end of the nozzle spount from the base of the insert thereby causing bubbling back of fuel delivered from an improper nozzle. Fuel bubbling back impinges on the automatic shutoff sensor of the nozzle to stop the fuel delivery.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
178 words
A device to reject a nozzle spout having a maximum crosssectional dimension greater than a predetermined magnitude and to accept a nozzle spout having a maximum cross-sectional dimension equal to or less than the predetermined magnitude, said device comprising a member positioned within an inlet of a container including a wall portion extending generally in the axial direction of the inleT and a substantially perpendicular downstream partially closed end portion having an opening having a cross-sectional dimension equal to a predetermined magnitude therein constructed to accept a nozzle spout of a maximum cross-sectional dimension of said predetermined magnitude or less and to reject a nozzle spout of a maximum cross-sectional dimension greater than said predetermined magnitude, said member including spaced abutment means protruding from said wall portion upstream of said end portion and being axially engageable with the delivery end of a nozzle spout of a dimension greater than said predetermined magnitude to prevent said delivery end from axially engaging said end portion and to maintain said delivery end in a position spaced upstream from said end portion.
Claim 2
Independent Claim
178 words
A device to reject a nozzle spout having a maximum crosssectional dimension greater than a predetermined magnitude and to accept a nozzle spout having a maximum cross-sectional dimension equal to or less than the predetermined magnitude, said device comprising a member positioned within an inlet of a container including a wall portion extending generally in the axial direction of the inleT and a substantially perpendicular downstream partially closed end portion having an opening having a cross-sectional dimension equal to a predetermined magnitude therein constructed to accept a nozzle spout of a maximum cross-sectional dimension of said predetermined magnitude or less and to reject a nozzle spout of a maximum cross-sectional dimension greater than said predetermined magnitude, said member including spaced abutment means protruding from said wall portion upstream of said end portion and being axially engageable with the delivery end of a nozzle spout of a dimension greater than said predetermined magnitude to prevent said delivery end from axially engaging said end portion and to maintain said delivery end in a position spaced upstream from said end portion.
Claim 3
Dependent Claim
20 words
Means according to claim 1, said abutment means comprising at least one ramp member positioned upstream of said end portion.
Claim 4
Dependent Claim
52 words
Means according to claim 1, said abutment means comprising a plurality of ramp members disposed about said opening and extending upstream from the periphery of said opening, said ramp members providing a means to guide a nozzle spout of a diameter equal to or less than said predetermined magnitude into said opening.
Claim 5
Dependent Claim
154 words
An inlet pipe insert for a storage container constructed to selectively accept and reject pump nozzle spouts on the basis of outer diameter magnitude, said insert comprising: a cup member secured within an inlet pipe, said cup member including a wall portion extending axially inwardly into said inlet pipe and a downstream partially closed end portion joining said wall portion and being substantially perpendicular thereto, an orifice having a cross-sectional dimension equal to a predetermined magnitude formed in said end portion of said cup member, spaces abutment means protruding from said wall portion upstream of said end portion and being axially engageable with the delivery end of a nozzle spout of a diameter greater than said predetermined magnitude to prevent engagement between the just-mentioned nozzle spout and said end portion of said cup member and to maintain the delivery end of said just-mentioned nozzle spout in a position spaced upstream from said end portion.
Claim 6
Dependent Claim
154 words
An inlet pipe insert for a storage container constructed to selectively accept and reject pump nozzle spouts on the basis of outer diameter magnitude, said insert comprising: a cup member secured within an inlet pipe, said cup member including a wall portion extending axially inwardly into said inlet pipe and a downstream partially closed end portion joining said wall portion and being substantially perpendicular thereto, an orifice having a cross-sectional dimension equal to a predetermined magnitude formed in said end portion of said cup member, spaces abutment means protruding from said wall portion upstream of said end portion and being axially engageable with the delivery end of a nozzle spout of a diameter greater than said predetermined magnitude to prevent engagement between the just-mentioned nozzle spout and said end portion of said cup member and to maintain the delivery end of said just-mentioned nozzle spout in a position spaced upstream from said end portion.
Claim 7
Dependent Claim
29 words
An insert according to claim 4, said abutment means comprising at least one ramp member extending inwardly from said wall portion of said cup member toward said end portion.
Claim 8
Dependent Claim
64 words
An insert according to claim 4, said abutment means comprising a plurality of ramp members extending inwardly from said wall portion to said end portion, said ramp members terminating at the periphery of said orifice formed in said end portion, said ramp members providing means to guide a nozzle spout of a diameter equal to or less than said predetermined magnitude into said orifice.
Claim 9
Dependent Claim
65 words
An insert according to claim 4 usable in cooperation with a nozzle having an automatic shutoff sensor located on the nozzle spout at a position spaced from the delivery end of said spout, said cup member having a depth sufficient to receive within said wall portion the automatic shut-off sensor of such a nozzle having a spout of a diameter greater than said predetermined magnitude.
Claim 10
Dependent Claim
17 words
An insert according to claim 4, vent means formed in an upstream portion of said cup member.
Claim 11
Dependent Claim
207 words
A liquid storage tank inlet pipe insert constructed to selectively accept and reject pump nozzle spouts on the basis of outer diameter magnitude, said insert comprising: a cup member including a first portion secured to an inlet pipe, an axially extending cylindrical wall portion of a diameter smaller than that of the inlet pipe, said cylindrical wall portion having an upstream end and a downstream end, an intermediate portion joining said first portion and the upstream end of said cylindrical wall portion, an end portion joining said cylindrical wall portion at the downstream end thereof, an orifice having a cross-sectional dimension equAl to a predetermined magnitude formed in said end portion to receive nozzle spouts having diameters equal to or less than said predetermined magnitude, vent means independent of said orifice formed in said intermediate portion, spaced abutment means upstream of said end portion and protruding radially inwardly from said cylindrical wall, said abutment means being axially engageable with the delivery end of a nozzle spout of a diameter greater than said predetermined magnitude and defining an obstruction to said justmentioned nozzle spout to prevent insertion thereof into said orifice and to maintain the delivery end of said just-mentioned nozzle spout axially spaced from said end portion.
Claim 12
Dependent Claim
