Abstract

460,785. Extruding clay &c. WILLIS, J. M., and WILLIS, C. L. Aug. 31, 1935, No. 24350. [Class 87 (ii)] In apparatus for de-airing clay and like plastic substances comprising a vertical deairing chamber and a horizontal pug mill, one or more rollers or equivalent members are disposed at the sides of the chamber parallel with and close to the worm of the pug mill so as to direct the clay into the path of the worm while leaving a free passage for the material through the chamber. Clay is fed by a worm 10 into the de-airing chamber 14 through a pair of perforated plates 12, 13, one of which is fixed while the other rotates with the worm shaft. A roller 20 is mounted in a semicircular enlargement 22 of the chamber wall and rotates in the opposite direction to the worm 17 of the pug mill. A similar roller or a paddle 21 is mounted in another enlargement on the other side of the chamber. The spindles of the rollers and worm project through the casing and are connected by gearing 25. The roller and paddle are preferably of smaller diameter than the worm 17 and are driven at a higher speed. Specification 421,860 is referred to.
