Abstract

A method of installing a vibratory shaker screen in a vibratory shaker, including placing a first end of the vibratory shaker screen in a retainer, wherein the retainer is a component of the vibratory shaker; pivoting a second end of the vibratory shaker screen toward a screen installation position on the vibratory shaker, deflecting a tab on one of the vibratory shaker screen and the vibratory shaker through contact of the vibratory shaker screen to another retainer of the vibratory shaker, and connecting the vibratory shaker screen to the vibratory shaker, where the tab fixedly connects the vibratory shaker screen to the vibratory shaker.

First claim

What is claimed is:

1. A method of installing a vibratory shaker screen in a vibratory shaker, comprising:
placing a first end of the vibratory shaker screen in contact with a first retainer of the vibratory shaker;
pivoting a second end of the vibratory shaker screen toward a screen installation position on the vibratory shaker;
deflecting a tab on the vibratory shaker screen through contact of the vibratory shaker screen to a second retainer of the vibratory shaker during the pivoting; and
connecting the vibratory shaker screen to the vibratory shaker, wherein the tab is positioned into a non-deflected position in contact with the second retainer such that the vibratory shaker screen is fixedly attached to the vibratory shaker.

2. The method of claim 1 , further comprising transmitting a notification to an operator when the non-deflected position is achieved.

3. The method of claim 2 , wherein the notification is a visual notification.

4. The method of claim 2 , wherein the notification is an audible notification.

5. A vibratory shaker screen, comprising:
a mesh supporting system having at least one tab configured to move from an un-deflected position to a deflected position, the at least one tab configured to move to the deflected position upon placement of a force on the at least one tab, and the at least one tab further configured to return to the un-deflected position upon removal of the force; and
at least one mesh portion disposed on the mesh supporting system,
wherein the mesh supporting system has four side members, a top face, and a bottom face, and wherein the at least one tab has an angled surface and a bottom edge.

6. The vibratory shaker screen of claim 5 , wherein the at least one tab is placed on one of the four side members.

7. The vibratory shaker screen of claim 5 , wherein each of the four side members of the vibratory mesh supporting system has at least two tabs.

8. The vibratory shaker screen of claim 5 , wherein the at least one tab is configured with a deflection area between the at least one tab and a remainder of the mesh supporting system.

9. The vibratory shaker screen of claim 5 , wherein the at least one tab has a depth and a lock surface, and both the depth and the lock surface are configured to abut a retainer of a vibratory shaker.

10. The vibratory shaker screen of claim 9 , wherein the depth and the lock surface are configured at 90 degrees.

11. The vibratory shaker screen of claim 5 , wherein the at least one mesh portion is made of a metal.

12. The vibratory shaker screen of claim 5 , wherein the at least one mesh portion is made of one of a polymer and a composite material.

13. The vibratory shaker screen of claim 5 , wherein the at least one mesh portion is connected to the top face.

14. The vibratory shaker screen of claim 13 , wherein the at least one tab is positioned on one of the four side members of the mesh supporting system.

15. A vibratory shaker screen, comprising:
a mesh supporting system having a top face and a bottom face, the mesh supporting system forming a frame with at least one side of the frame having at least one tab configurable in an un-deflected position and a deflected position, wherein each of the at least one tab is configured to deflect upon placement of a force upon the tab and is further configured to return to the un-deflected position upon removal of the force, and wherein the mesh supporting system has a top face and a bottom face;
a first mesh portion connected to the top face of the mesh supporting system; and
a second mesh portion connected to the bottom face of the mesh supporting system,
wherein the at least one tab has an angled exterior surface and a bottom edge, and the tab is configured from portions of the frame.

16. The vibratory shaker screen of claim 15 , wherein the frame is tubular.

17. The vibratory shaker screen of claim 15 , wherein the frame has a first side and a second side and at least one structural element extending from the first side to the second side.

18. The vibratory shaker screen of claim 15 , wherein the first mesh portion and the second mesh portion are configured in a wave form.

19. A method of installing a vibratory shaker screen in a vibratory shaker, comprising:
placing a first end of a vibratory shaker screen in contact with a vibratory shaker;
placing a second end of the vibratory shaker screen in contact with the vibratory shaker;
applying a force onto the vibratory shaker screen to deflect at least one tab on one of the vibratory shaker screen and the vibratory shaker; and
connecting the vibratory shaker screen to the vibratory shaker, wherein the at least one tab is positioned into a non-deflected position such that the vibratory shaker screen is fixedly attached to the vibratory shaker.

20. The method according to claim 19 , wherein the force applied to the vibratory shaker screen is a vertical force.

21. The method according to claim 19 , wherein the at least one tab is on the vibratory shaker screen.

22. The method according to claim 19 , wherein the at least one tab is on the vibratory shaker.
