Abstract

518,037. Squirting. HIGH DUTY ALLOYS, Ltd., and HERON, J. A. Sept. 13, 1938, No. 26685. [Class 83 (iv)] Bars having a varying cross section are made by extrusion through a die 3 the aperture of which is varied in consonance with the movement of the ram 5 by one or more laterally moving slides 18. Each slide is moved directly or through mechanism by an inclined or cam-faced rod 11 connected with, or moved at desired ratio relative to, the ram 5. If more than one slide is used their movements may be similar or dissimilar. In a modification the die with its slide or slides is adapted to move forward a short distance during extrusion, the slides being operated by stationary, guideways. A similar arrangement can be applied when a hollow ram forces the die into a container having a closed rear.
