| 20110314652 | SCREENING MACHINE AND ASSOCIATED SCREEN PANEL - A screening machine of the type used to separate or classify mixtures of solid particles of different sizes includes a fixed base and a perforate screen mounted for movement relative to the base during a screening operation. The screens are pre-tensioned and mounted in a perimeter frame for separating various granular and particulate material. The frame is slid into the side of the machine in a direction parallel with two opposing bevel lips at the ends of the frame which mate in the screening machine with a complementary channel such that when the screen is raised into sealing contact in the screening machine, the bevel ends of the screen panel frame align the screen panel in the machine. The bevels on the screen panel frame provide a positive sealing surface for contact with the adjacent portions of the channel to prevent product from escaping off of the screen during use. | 12-29-2011 |
| 20110000828 | SCREENING MACHINE WITH SEGMENTED SCREEN PANELS - A screen panel assembly is used with a screening machine. The screen panel assembly includes first and second generally planar screen panels and a coupling between the first and second screen panels that includes latching mechanisms to temporarily secure the screen panels together. An overlap region between the first and second screen panels permits lifting of the second screen panel by a lifting force exerted upon the first screen panel while inhibiting the passage of material being screened between the two adjacent screen panels. | 01-06-2011 |
| 20100108579 | Screening Machine with Segmented Components - A screen frame assembly is provided for use with a screening machine. The screen frame assembly includes first and second generally planar screen frames and a coupling between the first and second screen frames that includes a tab in the first screen frame and a receiving slot in the second screen frame. The receiving slot is configured to receive the tab and includes a centering feature for laterally aligning the first and second screen frames relative to one another. The centering feature may include a pair of opposed inwardly angled edges of the receiving slot. The coupling may include an overlap region between the first and second screen frames that is engageable to thereby permit lifting of the second screen frame by a lifting force exerted upon the first screen frame. | 05-06-2010 |

The screens are pre-tensioned and mounted in a perimeter frame for separating various granular and particulate material.

The bevels on the screen panel frame provide a positive sealing surface for contact with the adjacent portions of the channel to prevent product from escaping off of the screen during use. The sealing contact of the screen panel is enhanced by a seal member on the screen panel. | 01-28-2010 |
| 20090230029 | SCREENING MACHINE AND ASSOCIATED SCREEN PANEL - A screening machine of the type used to separate or classify mixtures of solid particles of different sizes includes a machine frame and a perforate screen panel mounted for movement relative to the machine frame during a screening operation. The screen panels are pre-tensioned mesh screen material mounted in a peripheral rim for separating various granular and particulate materials. The screen panel is slid into the side of the machine frame in a direction orthogonal to the direction particulate matter moves when the screening machine is operating. The screen panel peripheral rim has a shaped or other cross section adapted to hold a large seal member that provides a positive sealing surface for contact with the machine frame to prevent particulate matter from escaping off of the screen panel during use. | 09-17-2009 |
