SAFETY PRESSURE RELIEF APPARATUS Abstract of the Disclosure The present invention relates to a safety pressure relief apparatus comprised of a reverse buckling rupture disk having a concave-convex por- tion connected to an annular flat flange portion by a curved transition connection and a support member having an annular flat flange portion for engaging the annular flat flange portion of the rupture disk and for supporting the transition connection thereof. The support member includes a cutting edge positioned interiorly of the transition connection and forming an opening in the support member so that when the concave-convex portion of the rupture disk reverses itself, the cutting edge severs the disk whereby a portion thereof passes through the opening in the sup- port member. A bar for catching the severed portion of the disk after it passes through the opening in the support member is attached to the support member.
