Abstract

329,099. Vokes, C. G. March 28, 1929. Filtering. - An air filter comprises stiffened filtering material formed in pleats and held between end plates. The filter is a cylinder of star-shaped cross-section, and airtight joints 4 of felt or rubber are formed between the filter 1 and the end plates 2 and 3. The whole is firmly secured by a bolt 6 between the end plate 2 and a strip 5 attached to the plate 3. Fig. 4 shows a layer of felt 12 stiffened by two layers of gauze 13. In modifications, the felt 12 is replaced by finer gauze and also when felt is used the pleats are closed by extending the felt beyond the gauze and by stitching.
