Pipeline filter

1. A pipeline filter assembly comprising:

a) a base assembly having:

i) a filter base;

ii) a base plate upon which the pipeline filter assembly is configured to rest;

b) an outer wall having a lower end portion and an upper end portion, wherein the lower end portion is seated within the base assembly and the upper end portion comprises a lower collar seated thereon, the lower collar comprising at least one lock notch spaced around an exterior surface thereof; and

c) a lid assembly configured to couple to the lower collar of the outer wall, the lid assembly having:

i) an upper collar configured to threadedly mate with the lower collar, the upper collar having:

1) at least one housing that projects from the upper collar, the housing having an interior surface;

2) at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch; and

3) at least one biasing spring wherein an end of the biasing spring abuts the interior surface of the housing and biases its corresponding biasing clip to a locked position around a corresponding lock notch.

2. The pipeline filter assembly of claim 1 , further comprising an upper cover configured to secure to the outer wall via mating of the lower collar and the upper collar, the upper cover having:

a) a top surface;

b) at least one pressure gauge coupled to the top surface of the upper cover; and

c) at least one pressure relief valve coupled to the top surface of the upper cover.

3. The pipeline filter assembly of claim 1 , wherein the lock notch has an upper portion and a lower portion.

4. The pipeline filter assembly of claim 3 , wherein the biasing clip is in a primary locked position when the biasing clip is engaged with the lower portion of the lock notch, and the biasing clip is a secondary locked position when the biasing clip is engaged with the upper portion of the lock notch.

5. A method of disengaging the lid assembly from the pipeline filter assembly of claim 3 , the method comprising the steps of:

a) pulling the biasing clip outwards, towards the interior surface of the housing to disengage the biasing clip from the lower portion of the lock notch;

b) rotating the lid assembly until the biasing clip clears the lower portion of the lock notch;

c) releasing the biasing clip and continuing rotation of the lid assembly until the biasing clip engages the upper portion of the lock notch;

d) pulling the biasing clip outwards, towards the interior surface of the housing to disengage the biasing clip from the upper portion of the lock notch; and

e) continuing rotation of the lid assembly until the lid assembly is completely disengaged from the lower collar.

6. The pipeline filter assembly of claim 1 , wherein the biasing spring is mounted within a recess disposed within the biasing clip.

7. A pipeline filter assembly comprising:

a) a base assembly;

b) an outer wall having a lower end portion and an upper end portion, wherein the upper end portion comprises a lower collar, the lower collar comprising at least one lock notch spaced around an exterior surface thereof; and

c) a lid assembly configured to couple to the lower collar of the outer wall, the lid assembly having:

a) an upper collar configured to threadedly mate with the lower collar, the upper collar having:

i) at least one housing that projects from the upper collar, the housing having an interior surface;

ii) at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch; and

iii) at least one biasing spring within the housing that radially biases its corresponding biasing clip toward a central axis of the upper collar and to a locked position around a corresponding lock notch.

8. The pipeline filter assembly of claim 7 , wherein the base assembly comprises:

i) a filter base;

ii) a base plate upon which the pipeline filter assembly is configured to rest; and

iii) a support collar configured to couple to the base plate.

9. The pipeline filter assembly of claim 7 , further comprising an upper cover configured to secure to the outer wall via the mating of the lower collar and the upper collar.

10. The pipeline filter assembly of claim 7 , further comprising a filter base that has at least one inlet port for water to enter the pipeline filter assembly and at least one outlet port for water to exit the pipeline filter assembly.

11. The pipeline filter assembly of claim 7 , wherein there are a plurality of lock notches.

12. The pipeline filter assembly of claim 7 , further comprising the biasing spring mounted within a recess disposed within the biasing clip.

13. The pipeline filter assembly of claim 7 , where there are a plurality of biasing clips and biasing springs.

14. A pipeline filter system comprising:

a) a pair of pipeline filter assemblies, each assembly having:

i) a base assembly;

ii) an outer wall having a lower end portion and an upper end portion, wherein the lower end portion is coupled to the base assembly and the upper end portion comprises a lower collar, the lower collar comprising at least one lock notch spaced around an exterior surface thereof; and

iii) a lid assembly configured to couple to the lower collar of the outer wall, the lid assembly having:

1) an upper collar configured to threadedly mate with the lower collar, the upper collar having:

a) at least one housing that projects from the upper collar, the housing having an interior surface;

b) at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch; and

c) at least one biasing spring wherein an end of the biasing spring abuts the interior surface of the housing and biases its corresponding biasing clip to a locked position around a corresponding lock notch; and

2) an upper cover configured to secure to the outer wall via the mating of the lower collar and the upper collar; and

b) at least one connection plate.

15. The pipeline filter system of claim 14 , wherein each base assembly comprises a base plate having at least one alignment slot and the connection plate has at least one joining member that corresponds to the at least one alignment slot in the base plates.
