Abstract
A seal assembly for sealing the edges of a compartment and an adjacent surface which move relative to each other, including a resilient, transverse seal at the front and rear edges of the compartment arranged transversely of the direction of relative motion between the surface and compartment, each transverse seal extending a distance beyond the compartment greater than the distance between the surface and the compartment for enabling each transverse seal to bend rearwardly relatively to the direction of motion and firmly, sealingly engage the surface; and a resilient, longitudinal seal at each side edge of each compartment arranged generally longitudinally to the direction of relative motion between the surface and compartment, each longitudinal seal extending a distance beyond the compartment greater than the distance between the surface and compartment for enabling each longitudinal seal to be bent inwardly of the compartment, firmly, sealingly engage the surface and firmly clamp and sealingly engage the transverse seals after they have adjusted to the distance between the compartment and surface, and provide a positive seal about the edges of the compartment and against the surface.
