System and method for locking a weight assembly

1. A lock assembly for a vibratory separator, comprising:

a latch comprising:

a first inner protrusion; and

a first outer protrusion, wherein the first outer protrusion defines a first outer protrusion opening; and

a first spacer comprising a first fastener that is configured to be inserted into the first outer protrusion opening, wherein the first outer protrusion opening is an elongated opening extending in a direction perpendicular to the first fastener.

2. The lock assembly of claim 1 , wherein the first inner protrusion is configured to be inserted into a first weight arm opening in a weight arm.

3. The lock assembly of claim 2 , wherein the first outer protrusion is configured to be positioned laterally-offset from or laterally-abutting the weight arm when the first inner protrusion is inserted into the first weight arm opening.

4. The lock assembly of claim 3 , wherein the latch further comprises:

a second inner protrusion, wherein the second inner protrusion is configured to be inserted into a second weight arm opening in the weight arm; and

a second outer protrusion, wherein the first inner protrusion and the second inner protrusion are positioned between the first outer protrusion and the second outer protrusion, wherein the weight arm is configured to be positioned between the first outer protrusion and the second outer protrusion when the second inner protrusion is inserted into the second weight arm opening, and wherein the second outer protrusion defines a second outer protrusion opening.

5. The lock assembly of claim 4 , further comprising a second spacer comprising a second fastener that is configured to be inserted into the second outer protrusion opening, wherein the second outer protrusion opening is an elongated opening extending in a direction perpendicular to the second fastener.

6. The lock assembly of claim 1 , wherein the first spacer defines a first spacer opening that is substantially perpendicular to the first fastener.

7. The lock assembly of claim 6 , further comprising a second third fastener that is configured to be inserted into the first spacer opening, such that the first fastener is substantially perpendicular to the second third fastener.

8. The lock assembly of claim 1 , wherein the first spacer comprises a rectangular body configured to be positioned within a first recess defined at least partially between an upper weight plate and a lower weight plate, wherein the first spacer further comprises a cylindrical fastener protruding from the rectangular body.

9. The lock assembly of claim 1 , wherein the latch further comprises a top central protrusion defining a top central protrusion opening, wherein the top central protrusion opening is configured to receive a central tab attached to an upper weight plate.

10. A system, comprising:

a weight assembly comprising:

a weight arm defining a first weight arm opening;

an upper weight plate; and

a lower weight plate, wherein the weight arm is positioned at least partially between the upper weight plate and the lower weight plate; and

a lock assembly comprising:

a latch comprising:

a first inner protrusion configured to be inserted into the first weight arm opening; and

a first outer protrusion that defines a first outer protrusion opening; and

a first spacer configured to be positioned within a first recess defined at least partially between the upper weight plate and the lower weight plate, wherein the first spacer comprises a first fastener that is configured to be inserted into the first outer protrusion opening, wherein the first outer protrusion opening is an elongated opening extending in a direction perpendicular to the first fastener.

11. The system of claim 10 , wherein the first outer protrusion is configured to be positioned laterally-offset from or laterally-abutting the weight arm when the first inner protrusion is inserted into the first weight arm opening.

12. The system of claim 10 , wherein the first spacer defines a first spacer opening that is substantially perpendicular to the first fastener, and wherein the lock assembly further comprises a third fastener that is configured to be inserted into the first spacer opening, such that the first fastener is substantially perpendicular to the third fastener.

13. The system of claim 10 , wherein the latch further comprises:

a second inner protrusion, wherein the second inner protrusion is configured to be inserted into a second weight arm opening in the weight arm; and

a second outer protrusion, wherein the first inner protrusion and the second inner protrusion are positioned between the first outer protrusion and the second outer protrusion, wherein the weight arm is positioned between the first outer protrusion and the second outer protrusion when the second inner protrusion is inserted into the second weight arm opening, and wherein the second outer protrusion defines a second outer protrusion opening.

14. A method, comprising:

positioning a first spacer at least partially within a first recess defined between an upper weight plate and a lower weight plate, wherein the first spacer comprises a first fastener;

inserting a third fastener at least partially through a first spacer opening in the first spacer;

positioning a latch such that the first fastener extends through a first outer protrusion opening in the latch, wherein the latch comprises a first outer protrusion that defines the first outer protrusion opening and the first outer protrusion opening is an elongated opening extending in a direction perpendicular to the first fastener;

moving the latch in a first direction to align a first inner protrusion of the latch with a first weight arm opening in a weight arm, wherein the weight arm is positioned at least partially between the upper weight plate and the lower weight plate; and

moving the latch in a second direction to insert the first inner protrusion at least partially into the first weight arm opening.

15. The method of claim 14 , wherein the upper weight plate defines an upper weight plate opening, wherein the lower weight plate defines a lower weight plate opening, and wherein positioning the first spacer comprises aligning the first spacer opening with the upper weight plate opening and the lower weight plate opening.

16. The method of claim 15 , wherein inserting the third fastener comprises inserting the third fastener through the upper weight plate opening, the first spacer opening, and the lower weight plate opening.

17. The method of claim 16 , wherein the third fastener is substantially perpendicular to the first fastener when the third fastener is inserted.

18. The method of claim 14 , wherein the first recess is defined at least partially by the upper weight plate, the lower weight plate, and the weight arm.

19. The method of claim 14 , wherein the first direction is substantially parallel to a central longitudinal axis through the weight arm, and wherein the second direction is substantially perpendicular to the first direction.

20. The method of claim 14 , wherein the first fastener remains extending through the first outer protrusion opening while the latch is moved in the first direction and the second direction.
