Vibrating screen assembly with integrated gasket and frame

Abstract

A vibrating screen assembly having a tubular frame. The tubular frame includes a pair of opposed tubular sides and a pair of opposed tubular ends. An upstanding lip extending from each side and extending from each end forms a rim enclosure. A ledge extends inwardly from the opposed sides. A perforated plate with a plurality of screen cloths thereon is positioned within the rim enclosure and secured to a planar surface of the frame. A slot in the tubular sides and tubular ends forms a continuous channel and an elastomeric gasket is press fit into the slot and held therein without adhesives or fasteners.

         8 . A vibrating screen assembly as set forth in  claim 3  wherein said screen cloths are bonded to said perforated plate by heat and pressure.  
     
     
         9 . A vibrating screen assembly as set forth in  claim 3  wherein said perforated plate and said screen cloths are secured to said frame by adhesive.  
     
     
         10 . A vibrating screen assembly as set forth in  claim 2  wherein said slot is in an underside of said sides and said ends opposed to said planar surface and forms a continuous channel.  
     
     
         11 . A vibrating screen assembly as set forth in  claim 1  wherein said elastomeric gasket is elastomeric, compressible and resilient.  
     
     
         12 . A vibrating screen assembly as set forth in  claim 1  wherein said elastomeric gasket is fabricated from neoprene.  
     
     
         13 . A vibrating screen assembly as set forth in  claim 1  wherein said gasket is fabricated from polyethylene.  
     
     
         14 . A vibrating screen assembly as set forth in  claim 1  wherein said gasket is cut to size from extruded lengths.  
     
     
         15 . A vibrating screen assembly as set forth in  claim 1  wherein said elastomeric gasket has a lower surface to rest on a vibrating shaker, a reduced portion having a width less than a width of said slot, and an upper portion having a width larger than said width of said slot.  
     
     
         16 . A vibrating screen assembly which comprises: 
 a continuous frame including a pair of side tubes, each said tube having a planar surface;    a slot in said continuous frame;    an elastomeric gasket mechanically locked in said slot without adhesive or fasteners; and    a perforated plate with at least one screen cloth thereon and secured to said planar surface.    
     
     
         17 . A vibrating screen assembly as set forth in  claim 16  including a plurality of tubular cross supports.  
     
     
         18 . (Canceled)  
     
     
         19 . (Canceled)  
     
     
         20 . A vibrating screen assembly as set forth in  claim 16  wherein said slot is in an underside of said continuous frame opposed to said planar surface and forms a continuous channel.  
     
     
         21 . A vibrating screen assembly as set forth in  claim 16  wherein said gasket is elastomeric, compressible and resilient.  
     
     
         22 . A vibrating screen assembly as set forth in  claim 16  wherein said gasket is cut to size from extruded lengths.  
     
     
         23 . (Canceled)  
     
     
         24 . (Canceled)  
     
     
         25 . A vibrating screen assembly as set forth in  claim 15  wherein said gasket has a lower surface to rest on a vibrating shaker, a reduced portion having a width less than a width of said slot, and an upper portion having a width larger than said width of said slot.  
     
     
         26 . A vibrating screen assembly which comprises: 
 a frame having a pair of opposed tubular sides;    a slot in at least said tubular sides;    means for sealing said tubular sides to said frame; and    at least one screen cloth supported on said frame.
