Abstract

6346. Herbert, A., and Vernon, P. V. March 14. Screwing-die heads.-In a screwing-die head of the type described in Specification 4033/02, scroll cams are provided to engage shoulders on each side of and directly behind the cutting- portion of each die so as to prevent longitudinal tilting. The cams J, K are provided with camsurfaces G, H to engage the parts E, F of the dies. They also have cam-grooves M engaging ribs L on the dies for withdrawal purposes. Any number of engaging surfaces E, F, portions L, and scrolls may be used. The front scroll member J can be made very thin so that the dies can cut close up to the support.
