Abstract

430,006. Squirting. PIRELLI-GENERAL CABLE WORKS, Ltd., and HORLEY, R. E., 343, Euston Road, London. Dec. 1, 1933, Nos. 33852/33 and 12649/34. [Class 83 (iv)] The impelling-device of an extrusion press for solid or tubular sections, or for cable sheaths, comprises a rotary sleeve 3 having screw-threads on the inner and outer surfaces, and working within stationary cylindrical members 1, 2, the surfaces of which are preferably broken up by grooves, recesses, ribs, or the like 4, 5. Ports 8 communicate between the lead inlet 7 and the inner surface of the impeller. Annular grooves 12 are formed in the bearing-surfaces so that escaping lead may be solidified therein by cooling means and retained to seal the apparatus against further escape of lead. The ports 8 may be omitted or restricted, and the inner screw-threads 6 supplied with lead from the die chamber, the balance between the pressure of lead and the impelling force of the inner screw-threads permitting the lead to fill only a part of the length of the threads, the inner grooves 12 then being unnecessary. Heating and cooling means are provided on the apparatus.
