Abstract

296,359. Garland, C. S. May 30, 1927. Filters and strainers having sheet filtering or straining materials; filters with loose filtering - materials; grids and gratings.-A filter or strainer has a surface of helically-woven wire or strip-like mesh supported so that it can be stretched longitudinally and the area of the meshes extended or contracted to give a greater or less degree of filtering permeability. The surface may be formed of interlaced coiled or helical springs. The straining surface 5, Fig. 3, is tubular, its ends being bound to end discs 7, 8. The disc 8 is formed in one with a central tube 8<h>, which serves for the discharge of the filtrate and has its upper end screwed to receive a nut 7g journaled in the disc 7. The filter surface is extended or contracted bv rotation of the nut. In the modification shown in Fig. 4, the straining surface 5 is extended by a piston 15<a>, which can be expanded by rotation of the piston rod 15, which slides through the disc 7. Fig. 6 shows an edge filter built up of annular elements 6 and surrounded by a mesh strainer 5 of the kind described. As shown in Fig. 7, a mesh strainer 5 and a perforated tube 4 form the inner and outer boundaries of an annular space packed with loose filtering-material 2. In assembling this filter element the material 2 is packed around the tube 4 in a removable outer cylinder which is afterwards replaced by the mesh 5. Several elements as described my be mounted in a plate 10, Fig. 8, held between flanges on a container 9 and a cover 11. The cover has a filtrate outlet 11<b>, the container a liquid inlet 9<b>, and an outlet 9<c> for deposit. In edge filters of the strip type the narrow pack edges may be protected by stout side bars of semi-circular section, the helical mesh tube being placed over the whole and tightened.
