Abstract

601,918. Filter elements. BRIGGS, S. W. Oct. 11, 1945, No. 26635. [Class 46] A filter comprises a tubular body of filtering medium consisting of plies of filtering material, one ply composed of ribbed cellulose wadding and another of filter paper, the wadding having only rib engagement with the filter paper. The cellulose wadding may be made as is described in U.S.A. Specification 2,092,548. As shown, the filter body 9 is composed of cellulose wadding 10 and a sheet of filter paper 11 folded together accordion fashion and bent round to form a tube secured by staples 121. The plies are secured together at the ends by staples 12. The tube 9 is mounted around a perforated cylindrical core 1 and is joined at its ends 13 to annular plates 5 by means of cement. It is surrounded by a perforated tube of thick paper 14. The end plates 5 are provided with wells 7 in which are arranged resilient washers 18 having holes 19 to receive pipes, and retained by dished washers 16. The core 11 may be supported inside by a wire spiral 4 and is provided with beaded ends 3 which are secured, by spinning, in the wells 7 of the annular end plates 5.
