Abstract
Abstract An arming unit which is capable of releasing in the armed or unarmed position a weapon. This arming unit is made up of an arming wire connected at one end to the weapon and at the other end to a locking member which is releasably secured to an aircraft. A uniquely designed spring loop and plate arrangement of the arming wire allows for arming of the weapon and then subsequent release of the arming wire along with the weapon from the locking member. If desired, however, the arming wire and locking member may also be released together with the weapon in the unarmed position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
An arming unit adapted to be used with a weapon comprising an arming wire operably connected at one end to the fuze of said weapon, a plate mounted on said weapon adjacent said arming wire, said plate having a slot therein of a predetermined width, said arming wire having a spring loop and a twisted segment at said on end thereof, said twisted segment being of a greater diameter than the width of said slot and said spring loop protruding through said slot in said plate, a locking member having a clevis at one end thereof secured to a swivel loop at the other end of said arming wire, means secured to said clevis for holding said swivel loop in place, and means mounted on a weapon delivery unit for releasably securing the other end of said locking member thereto whereby upon the release of said weapon from said delivery unit while said locking member is secured to said weapon delivery unit said spring loop passes through said slot in said plate until said twisted segment abuts said plate thereby arming said weapon by disconnecting said arming wire from said fuze.
Claim 2
Dependent Claim
191 words
An arming unit adapted to be used with a weapon comprising an arming wire operably connected at one end to the fuze of said weapon, a plate mounted on said weapon adjacent said arming wire, said plate having a slot therein of a predetermined width, said arming wire having a spring loop and a twisted segment at said on end thereof, said twisted segment being of a greater diameter than the width of said slot and said spring loop protruding through said slot in said plate, a locking member having a clevis at one end thereof secured to a swivel loop at the other end of said arming wire, means secured to said clevis for holding said swivel loop in place, and means mounted on a weapon delivery unit for releasably securing the other end of said locking member thereto whereby upon the release of said weapon from said delivery unit while said locking member is secured to said weapon delivery unit said spring loop passes through said slot in said plate until said twisted segment abuts said plate thereby arming said weapon by disconnecting said arming wire from said fuze.
Claim 3
Dependent Claim
24 words
An arming unit as defined in claim 1 wherein said means for releasably securing said locking member is in the form of a solenoid.
Claim 4
Dependent Claim
46 words
An arming unit as defined in claim 2 wherein said locking member has a ball at said other end thereof and said solenoid has a pair of fixed sides and a pair of pivotally mounted jaws for engaging said ball, said jaws having a cylindrical cross-bore.
Claim 5
Dependent Claim
47 words
An arming unit as defined in claim 7 wherein said means for holding said swivel loop in place is a shear wire whereby a predetermined time after said twisted segment abuts said plate said shear wire will sever thereby releasing said arming wire from said locking member.
Claim 6
Dependent Claim
57 words
An arming unit as defined in claim 4 wherein said spring loop has a central section terminating at one end adjacent said twisted segment in a pair of reverse-tapered shoulders and the other end of said central section terminating in a pair of tapered shoulders and an extended segment which protrudes through said slot in said plate.
