Abstract
A seal for adjoining screen assemblies for vibrating machinery, where each screen assembly has a frame. The frame includes a planar surface. A perforated plate with a plurality of screen cloths thereon is secured to the planar surface of the frame. A first end of the frame has a seal shoulder. A second end of the frame has a seal bracket. The seal bracket of a first screen assembly engages a shoulder of a vibrating screen assembly to form a liquid seal between adjoining frames.

A seal mechanism between adjoining screen assemblies for vibrating machinery, in order to prevent leakage of liquids between the screen assemblies, the assemblies comprising:
- a first and second screen assembly, each screen assembly having a frame, a first opposed end and a second opposed end, comprising:
- a plurality of screen cloths supported on a planar surface of said frame;
- a first seal bracket on an underside of said second opposed end of said first screen assembly including an end stop extending vertically from said underside;
- a second seal bracket on an underside of said second opposed end of said second screen assembly including an end stop extending vertically from said underside;
- a convex first seal shoulder on said planar surface first opposed end of said first screen assembly;
- a convex second seal shoulder on said planar surface first opposed end of said second screen assembly;
- and
- said seal shoulder engaging said bracket to prevent leakage of liquids between the screen assemblies.
A process to produce a screen assembly for use with vibrating machinery, which process comprises:
- extruding sides of a frame having a top planar surface for supporting a plurality of screen lacers and an opposed inwardly extending ledge;
- extruding a first opposed end of said frame;
- extruding a second opposed end of said frame having a seal bracket extending vertically from an underside of said frame;
- cutting said sides and ends of said frame to desired lengths at 45° angles;
- connecting said opposed sides, a first opposed end and a second opposed end together to form a frame;
- connecting a plurality of tubular cross supports to said frame sides;
- bonding a plurality of screen cloths to a perforated plate;
- and
- securing said perforated plate, said screen cloths and a convex seal shoulder to said top planar surface frame.
