Abstract

749.957. Stuffing-box substitutes. BADISCHE ANILIN- & SODA-FABRIK AKT.- GES. June 11, 1954 [June 25, 1953], No. 17189/54. Class 122(5) - The rotary and reciprocating endless screw shaft 5 of a kneading machine, particularly for dyestuff pastes, is sealed by supplying liquor to a sealing zone 7 which is located axially between the shaft bearing 1 and the charging chamber 2 and separated from the bearing 1 by a chamber 4 and has an axial length l greater than the stroke h of the shaft. The zone 7 is formed by the gap between a piston 6, detachably secured to the shafts, and the shaft housing 8 and sealing liquid, preferably the same as that used in making the paste to be kneaded, is fed through a nozzle 9, any leakage from the zone 7 being drained through an opening 10 in the chamber. The cuter periphery of the piston may be grooved to form tapered teeth or provided with a screw-thread, preferably a multi-start one having a pitch greater than h, to oppose leakage.
