Abstract
Abstract A fuel filter having two easily gripped sediment bowls with a filter element and seal disposed therebetween and wherein each sediment bowl is constructed internally such that a sediment chamber is provided in either the horizontal or vertical position thus providing a filter element which is mountable in any position yet which will still provide proper filtering action. Further, with the use of an adapter, either bowl may be directly attached to a carburetor, thus allowing the novel filter to be used as either an incline filter or a carburetor attached filter.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
175 words
A fuel filter comprising: a. A fuel filter element having an annular mounting flange at its greatest diameter, b. a cup-shaped member having a tubular wall terminating in an annular end edge and a bottom with a port in the bottom extending outwardly for receiving a hose connection and inwardly to form a sediment chamber whether the cup-shaped member is in a vertical or horizontal position, and c. a retaining seal having three annular grooves therein, 1. one of said annular grooves opening radially inwardly and receiving the mounting flange of the filter element, 2. another of said annular grooves opening axially of the seal and receiving the annular end edge of the tubular wall to provide a liquidtight seal with the cup-shaped member, 3. the remaining annular groove opening axially of the seal between the first two annular grooves and defining in the seal an annular flexible wall whereby vibrations received by said cup-shaped member are transmitted to said filter element causing it to vibrate and wash itself in fuel in said cupshaped member.
Claim 2
Dependent Claim
175 words
A fuel filter comprising: a. A fuel filter element having an annular mounting flange at its greatest diameter, b. a cup-shaped member having a tubular wall terminating in an annular end edge and a bottom with a port in the bottom extending outwardly for receiving a hose connection and inwardly to form a sediment chamber whether the cup-shaped member is in a vertical or horizontal position, and c. a retaining seal having three annular grooves therein, 1. one of said annular grooves opening radially inwardly and receiving the mounting flange of the filter element, 2. another of said annular grooves opening axially of the seal and receiving the annular end edge of the tubular wall to provide a liquidtight seal with the cup-shaped member, 3. the remaining annular groove opening axially of the seal between the first two annular grooves and defining in the seal an annular flexible wall whereby vibrations received by said cup-shaped member are transmitted to said filter element causing it to vibrate and wash itself in fuel in said cupshaped member.
Claim 3
Dependent Claim
29 words
another of said annular grooves opening axially of the seal and receiving the annular end edge of the tubular wall to provide a liquidtight seal with the cup-shaped member,
Claim 4
Dependent Claim
29 words
another of said annular grooves opening axially of the seal and receiving the annular end edge of the tubular wall to provide a liquidtight seal with the cup-shaped member,
Claim 5
Dependent Claim
81 words
A fuel filter comprising: a. a fuel filter element having an annular mounting flange at its greatest diameter, b. a pair of identical cup-shaped members each having a tubular wall terminating in an annular end edge and a bottom formed with a port, said cup-shaped members cooperating to form a sediment bowl for fuel passing from one port to the other regardless of the position in which said mounting device is mounted, c. a retaining seal having three annular grooves therein,
Claim 6
Dependent Claim
81 words
A fuel filter comprising: a. a fuel filter element having an annular mounting flange at its greatest diameter, b. a pair of identical cup-shaped members each having a tubular wall terminating in an annular end edge and a bottom formed with a port, said cup-shaped members cooperating to form a sediment bowl for fuel passing from one port to the other regardless of the position in which said mounting device is mounted, c. a retaining seal having three annular grooves therein,
Claim 7
Dependent Claim
31 words
another of said annular grooves opening axially of the seal and receiving the end edge of the tubular wall of one cup-shaped member thereby providing a seal between said cup-shaped members,
Claim 8
Dependent Claim
31 words
another of said annular grooves opening axially of the seal and receiving the end edge of the tubular wall of one cup-shaped member thereby providing a seal between said cup-shaped members,
Claim 9
Dependent Claim
60 words
the remaining annular groove opening axially of the seal between the first two annular grooves and defining in the seal a flexible wall whereby vibrations received by said cup-shaped members are transmitted to said filter element causing it to vibrate and wash itself in fuel in said cup-shaped members, and d. means to maintain said cup-shaped members in assembled relation.
Claim 10
Dependent Claim
60 words
the remaining annular groove opening axially of the seal between the first two annular grooves and defining in the seal a flexible wall whereby vibrations received by said cup-shaped members are transmitted to said filter element causing it to vibrate and wash itself in fuel in said cup-shaped members, and d. means to maintain said cup-shaped members in assembled relation.
Claim 11
Dependent Claim
50 words
the remaining annular groove opening axially of the seal between the first two annular grooves and defining in the seal an annular flexible wall whereby vibrations received by said cup-shaped member are transmitted to said filter element causing it to vibrate and wash itself in fuel in said cup-shaped member.
Claim 12
Dependent Claim
50 words
the remaining annular groove opening axially of the seal between the first two annular grooves and defining in the seal an annular flexible wall whereby vibrations received by said cup-shaped member are transmitted to said filter element causing it to vibrate and wash itself in fuel in said cup-shaped member.
