Total Claims: 5
Claim 1
Independent Claim
167 words
An arming assembly for an air-delivered ordnance vehicle comprising: an arming device including a substantially cylindrical housing; a movable arming member having detonating paths formed therein and normally positioned in an out-of-line position with respect to an explosive train; a blocking member comprising an elongate plunger normally disposed in a first position restrainingly contacting said arming member in said out-of-line position; blocking member moving means comprising a rotatable and axially movable blocking ring normally engaging said plunger on its lower surface and maintaining said plunger in said first position, a rotatable and axially movable striker member coupled to said blocking ring through an elongate stem, said stem connected at one end to said blocking ring by a shear member, and means for rotating said striker member, whereby rotation of said striker member causes said blocking ring to rotate; and means for substantially insulating said arming device from shock including a collar member having an axial bore formed therethrough, said collar member enclosing said housing in said bore.
