Said helical nm is at intervals provided all alon its lengthwith scra ers 3 to prevent the ormation of--a cake o? ness on the metallic web of the filter B, said Scrapers `3`being actuated by. compressed air. The Scrapers 3 are. vertically posltioned and are mounted b y means of a stem 33 with excessive thickwhich they. are providedon a framework 34 mounted' on the end of the stem 35 of a piston 37 adapted to reciprocate inside of a cylindrical ap 56 formed transversely in the helical rim v4 and in the wall of the cylinderl A, said piston stemA being guidedv 'through a hole in a transversal partition 57 of said gag. Interposed between that partition and t e piston 37 is a spiral'spring 36, andthe iston 37 is provided with a stop. 58. Be ind thepiston 37, there is a compressed air chamber `32 to which the air is admitted by a tube 32 inside of the heli- 32. Jn normal position the s rin 36 is to vmaintain the scraper 3 kintro uce `into the cylindrical untilit comes to a small distance 'from the metallic web of the filter" B, the spring 36 and the stop 58 being regulated in such a way that under the action of the compressed air on the vpiston 37, the scraper 4 will come to a distance of about i of an inch from t e metallic web ofthe iilter B.
