Abstract: 585,295. Filters. BRIGGS, S. W. Feb. 15, 1945, No. 3870. [Class 46] A filter element is in the form of a tubular body comprising an elongated web of cellulosic filter material folded to extend back and forth between the inner and outer peripheral surfaces, a tubular binding strip being secured to the inner folds which are in contact with each other. In the construction shown in Figs. 1 and 2, a web 1 of cellulosic material folded back and forth with the inner folds joined together by means of a binding strip 13, is mounted on a foraminous tube 2 and secured between end plates 4,5 by plaster of Paris 14. The web is formed with horizontal grooves 16. Instead of a single web two or more webs may be used to form the filter element. In the arrangement shown in Fig. 5, the stretches of the web are curved to be in contact with adjacent stretches and the material substantially fills the space between inner and outer foraminous tubes 21, 20. Strips of cellulosic material containing an absorbent such as bauxite may be inserted between stretches of the web. Perforations may be made at the folds of the web to facilitate filtration.
