  • Patent number: 11077465
    Abstract: Systems and methods for a screen assembly configurable in a multi-screen configuration. The screen assembly in the multi-screen configuration includes a lower shaker screen and an upper shaker screen. A track is configured to be disposed on an inside wall of a vibratory separator and includes an upper retainer and a lower retainer. A screen clamping assembly is disposed in the track and includes a small spacer disposed between the lower shaker screen and the upper shaker screen in the track when the screen assembly is in the multi-screen configuration. An actuator is disposed in the track and has a clamped position where the actuator is actuated to provide a clamping force to clamp the lower shaker screen, the upper shaker screen, and the small spacer between the upper retainer and the lower retainer of the track.

  • Patent number: 9937530
    Abstract: This disclosure is generally drawn to systems, devices, apparatus, and/or methods related to sealing mechanisms for vibratory separators. Specifically, the disclosed systems, devices, apparatus, and/or methods relate to seals having support(s) for improved installation in and/or removal from a vibratory separator. In some examples, an apparatus may include a seal and a support member. The seal may have two opposing side members and an end member coupled to and extending between the two opposing side members. The support member, which is at least partially rigid, may be coupled to the end member of the seal. In some examples, the support member may be integrated with or removably coupled to the seal.
