Abstract

A filter extractor may include a first gutter fixed to a tool body and a second gutter being pivotably connected to the tool body. Additionally, a lifting device may be provided on the filter extractor. The lifting device is configured to extend and retract a line through the first gutter and the second gutter to extract a filter from a fluid conduit.

First claim

What is claimed is:

1. A filter extractor, comprising:
a tool body;
a first gutter in the form of a first trough that is fixed to the tool body, wherein the first gutter is configured to support a first filter member;
a second gutter in the form of a second trough, wherein a bottom surface of the second trough is pivotably connected to a vertical support that is connected to the tool body, wherein the second gutter is configured to support a second filter member; and
a lifting device coupled to the tool body, wherein the lifting device is configured to extend and retract a line through the first gutter and the second gutter to extract at least one of the first filter member and the second filter member from a fluid conduit.

2. The filter extractor of claim 1 , further comprising a drip tray disposed at an incline below the first gutter.

3. The filter extractor of claim 2 , further comprising a drain valve coupled to the drip tray.

4. The filter extractor of claim 1 , wherein the second gutter has a first position and a second position, wherein the second gutter is aligned with the first gutter in the first position, and wherein the second gutter is aligned with an open end of the tool body in the second position.

5. The filter extractor of claim 4 , further comprising at least one locking pin to lock the second gutter in the first position or the second position.

6. The filter extractor of claim 4 , wherein the second gutter is connectable to a proximal end of the first gutter in the first position.

7. The filter extractor of claim 6 , wherein the lifting device is at a distal end of the second gutter when the second gutter is in the first position.

8. The filter extractor of claim 1 , wherein the first gutter is perforated.

9. The filter extractor of claim 1 , further comprising a hook at an end of the line.

10. The filter extractor of claim 1 , wherein the second gutter is mechanically, hydraulically, or pneumatically rotated.

11. The filter extractor of claim 1 , wherein the first trough and the second trough each comprise a cross-sectional shape of a semi-circle or an arc.

12. The filter extractor of claim 1 , wherein the second gutter is pivotable relative to the tool body while the first gutter remains stationary relative to the tool body.

13. The filter extractor of claim 1 , wherein the first gutter is fixed to the tool body by a support frame comprising a plurality of support legs.

14. The filter extractor of claim 1 , wherein the lifting device comprises a housing configured to support the line, wherein the line is extended and retracted from the housing.

15. The filter extractor of claim 1 , wherein the line is movable along at least a longitudinal axis of the first gutter.

16. The filter extractor of claim 1 , further comprising a support level coupled to a base of the tool body to level a height of the filter extractor.
