Abstract

A system includes a first screen having a first latch on a first end of the first screen, a second screen having a first catch on a first end of the second screen, and a screen adapter that connects the first screen and the second screen. The screen adapter includes an elongate body, a first catch formed on a first side of the elongate body that engages the first latch on the first end of the first screen, and a first latch formed on a second side of the elongate body that engages the first catch on the first end of the second screen. A method includes inserting a first screen into a vibratory separator, inserting a screen adapter into the vibratory separator, coupling the screen adapter to the first screen, inserting a second screen into the vibratory separator, and coupling the second screen to the screen adapter.

First claim

What is claimed is:

1. A system comprising:
a first screen having a first latch, a second latch and a first catch provided on a first end of the first screen;
a second screen having a first catch, a second catch and a first latch provided on a first end of the second screen; and
a screen adapter for connecting the first screen and the second screen, the screen adapter comprising:
an elongate body having a top surface, a bottom surface, a first side and a second side;
a first catch and a second catch formed on the first side of the elongate body that engage the first latch and the second latch, respectively, on the first end of the first screen;
a first latch and a second latch formed on the second side of the elongate body that engages the first catch and the second catch, respectively, on the first end of the second screen configured to engage another screen;
a third latch formed on the first side of the elongate body that engages the first catch on the first end of the first screen; and
a third catch formed on the second side of the elongate body that engages the first latch on the first end of the second screen,

wherein each latch comprises an extension portion and an engagement portion of the latch, and each catch comprises a recess, a guide portion and an engagement portion of the catch, and
further wherein each corresponding latch and catch are configured to couple the first screen, the second screen and the screen adapter, respectively, by latching and locking the engagement portion of each latch with the engagement portion of each catch, respectively.

2. The system according to claim 1 , wherein:
the first latch and second latch on the first end of the first screen are arranged in a first profile on the first end of the first screen; and
the first catch and second catch on the first end of the second screen are arranged in a second profile on the first end of the first screen.

3. The system according to claim 1 , wherein:
a top surface of the first screen is offset from a bottom surface of the first screen;
a top surface of the second screen is offset from a bottom surface of the second screen;
and

a top surface of the screen adapter is offset from a bottom surface of the screen adapter,
wherein the top surface of the first screen and the top surface of the screen adapter seal against each other, and
wherein the top surface of the second screen and the top surface of the screen adapter seal against each other.

4. The system according to claim 1 , wherein the first catch and the first latch are disposed substantially adjacent to the bottom surface of the elongate body.

5. The system according to claim 1 , wherein:
the first catch is arranged in a first profile on the first side of the elongate body, and
the first latch is arranged in a second profile on the second side of the elongate body.

6. A method comprising:
providing the system, according to claim 1 , comprising the first screen, the second screen and the screen adapter
inserting the first screen into a vibratory separator;
inserting the screen adapter into the vibratory separator;
coupling the screen adapter to the first screen;
inserting the second screen into the vibratory separator; and
coupling the second screen to the screen adapter.

7. The method according to claim 6 , wherein the first screen and the second screen are different types of screens.

8. The method according to claim 6 , wherein:
coupling the screen adapter to the first screen comprises:
aligning the first latch on the first side of the first screen with the first catch on the first side of the screen adapter; and
engaging the first latch on the first side of the first screen with the first catch on the first side of the screen adapter; and

coupling the screen adapter to the second screen comprises:
aligning the first latch on the second side of the screen adapter with the first catch on the first side of the second screen; and
engaging the first latch on the second side of the screen adapter with the first catch on the first side of the second screen.

9. The method according to claim 6 , wherein:
the first screen and the screen adapter are coupled by one of a group consisting of horizontally sliding the screen adapter into engagement with the first screen and vertically placing the screen adapter into engagement with the first screen; and
the screen adapter and the second screen are coupled by one of a group consisting of horizontally sliding the second screen into engagement with the screen adapter and vertically placing the second screen into engagement with the screen adapter.

10. The method according to claim 6 , further comprising:
removing the first screen, the screen adapter, and the second screen together from the vibratory separator by pulling on one of the first screen or the second screen.
