Safe and arm mechanism for an embedment anchor propellant

Claim 1

A safe and arm mechanism for igniting a propellant charge in an embedment anchor which comprises: a block having a first end and second end, said block adapted to be demountably coupled to the embedment anchor at said first end and having a longitudinal ''''Y'''' opening at said first end, a lateral opening adjacent said Y opening and away from said first end, and a pair of generally parallel longitudinal openings adjacent said lateral opening and away from said Y opening; a pair of firing pins adjustably housed in said pair of generally parallel longitudinal openings in said block, said firing pins being longitudinally movable in generally parallel longitudinal openings; chamber means having a first end and a second end, said first end of said chamber being adjustably coupled to said block adjacent said second end of said block; an out-of-line slider adjustably positioned in said lateral opening in said block, said slider being selectively movable relative to said longitudinal openings and said Y opening to align said longitudinal openings, said firing pins and said Y opening; a pair of detonators housed in said out-of-line slider; a safety pin connected to said out-of-line slider to keep said pair of detonators in said out-of-line slider out of alignment with said pair of generally parallel longitudinal openings in said block; a piston housed in said chamber, said piston being in communication with said pair of firing pins; a solenoid valve means secured in said chamber proximate said second end of said chamber for selectively exposing said piston in said chamber to ambient hydrostatic chamber; means for actuating said solenoid valve means.
