Abstract
Abstract A method of and apparatus for detecting and collecting spilled fuel products from fuel dispensers of the type that are customarily mounted on a raised concrete island. One or more deflectors are mounted within a casing for the fuel dispenser at an elevation higher than the raised island. The deflectors serve to redirect the spilled fuel onto the top of the raised island so that the existence of the spilled fuel may be detected and corrected. It is possible for the deflectors to include channel members and for the spilled fuel to be delivered to more than one location on the island. In another embodiment of the invention, the spilled fuel product is conveyed to a flame and vapor safe container for disposal or recovery.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
106 words
An apparatus for detecting spilled fuel products wherein a casing for a fuel dispenser is mounted on a raised island or other foundation on which said fuel dispenser is mounted, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said apparatus comprising: a. deflector means mounted within said casing at an elevation higher than said raised island, i. said inlet fuel pipe and said electrical conduit pipe extending through said deflector means, ii. said deflector means serving to redirect spilled fuel products onto said raised island thereby detecting the existence of a spilled fuel product within said casing.
Claim 2
Independent Claim
106 words
An apparatus for detecting spilled fuel products wherein a casing for a fuel dispenser is mounted on a raised island or other foundation on which said fuel dispenser is mounted, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said apparatus comprising: a. deflector means mounted within said casing at an elevation higher than said raised island, i. said inlet fuel pipe and said electrical conduit pipe extending through said deflector means, ii. said deflector means serving to redirect spilled fuel products onto said raised island thereby detecting the existence of a spilled fuel product within said casing.
Claim 3
Dependent Claim
31 words
An apparatus for detecting spilled fuel products as defined in claim 1 wherein said deflector means includes channel means for directing a spilled fuel product onto said island or other foundation.
Claim 4
Dependent Claim
30 words
An apparatus for detecting spilled fuel products as defined in claim 1 wherein said spilled fuel products cascades from a deflector member of said deflector means to said channel means.
Claim 5
Dependent Claim
34 words
An apparatus for detecting spilled fuel products as defined in claim 1 wherein said deflector means and channel means deflects spilled fuel products onto said island or other foundation at more than one location.
Claim 6
Independent Claim
102 words
An apparatus for collecting spilled fuel products wherein a casing for a fuel dispenser is mounted on a raised island or other foundation, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said apparatus comprising: a. deflector means mounted within said casing at an elevation higher than said raised island, i. said inlet fuel pipe and said electrical conduit pipe extending through said deflector means, ii. said deflector means including channel means, b. and conduit means communicating with said channel means to deliver said spilled fuel products to a flame and vapor safe container.
Claim 7
Independent Claim
102 words
An apparatus for collecting spilled fuel products wherein a casing for a fuel dispenser is mounted on a raised island or other foundation, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said apparatus comprising: a. deflector means mounted within said casing at an elevation higher than said raised island, i. said inlet fuel pipe and said electrical conduit pipe extending through said deflector means, ii. said deflector means including channel means, b. and conduit means communicating with said channel means to deliver said spilled fuel products to a flame and vapor safe container.
Claim 8
Independent Claim
97 words
A method of detecting spilled fuel products from a fuel dispensing apparatus having a casing mounted on a raised island or other foundation, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said method comprising the steps of a. positioning deflector means within said casing at an elevation higher than said raised island or other foundation, b. passing said inlet fuel pipe and said electrical conduit pipe through said deflector means, c. and directing said spilled fuel products by said deflector means onto said raised island or other foundation.
Claim 9
Independent Claim
97 words
A method of detecting spilled fuel products from a fuel dispensing apparatus having a casing mounted on a raised island or other foundation, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said method comprising the steps of a. positioning deflector means within said casing at an elevation higher than said raised island or other foundation, b. passing said inlet fuel pipe and said electrical conduit pipe through said deflector means, c. and directing said spilled fuel products by said deflector means onto said raised island or other foundation.
Claim 10
Dependent Claim
33 words
A method of detecting spilled fuel products as defined in claim 6 including the additional step of directing said spilled fuel products to a plurality of positions on said island or other foundation.
Claim 11
Dependent Claim
42 words
A method of detecting spilled fuel products as defined in claim 6 wherein said deflector means includes channel means and said method includes the step of cascading said spilled fuel products by gravity flow from said deflector means to said channel means.
Claim 12
Independent Claim
105 words
A method of collecting spilled fuel products from a fuel dispensing apparatus having a casing mounted on a raised island or other foundation, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said method comprising the steps of a. positioning deflector means within said casing at an elevation higher than said raised island or other foundation, b. passing said inlet fuel pipe and said electrical conduit pipe through said deflector means, c. including channel means in said deflector means, d. and conveying said spilled fuel product from said channel means to a flame and vapor safe container.
Claim 13
Independent Claim
105 words
A method of collecting spilled fuel products from a fuel dispensing apparatus having a casing mounted on a raised island or other foundation, said casing having at least one inlet fuel pipe and at least one electrical conduit pipe therein, said method comprising the steps of a. positioning deflector means within said casing at an elevation higher than said raised island or other foundation, b. passing said inlet fuel pipe and said electrical conduit pipe through said deflector means, c. including channel means in said deflector means, d. and conveying said spilled fuel product from said channel means to a flame and vapor safe container.
