Abstract
Abstract The invention relates to an ordnance item arming wire, of the type in which one end is anchored and the other end holds a fuze or the like in unarmed condition, and a housing for the wire, in the form of a generally U-shaped strip of plastic, rubber or the like forced into a groove or otherwise fastened to the ordnance item so that the open edges of the strip are forced together for protecting the wire against the weather and aerodynamic forces yet can be forced apart to permit sliding of an attachment bridle along the wire to an optimum position for attachment to any of variously positioned stations on different launcher racks.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
283 words
In an arming device wherein a trip mechanism on one object is adapted to be held in a safe or inoperable condition by a removable arming wire or cable; said one object is releasably fastened to a second object; and said arming wire or cable is adapted to be removed from said trip mechanism upon separation of said objects, the improvement comprising: at least one longitudinally slotted plastic sleeve of finite length attached to said one object; a bare arming wire or cable of finite length situated in said sleeve and protruding from the ends of said sleeve; said arming wiRe being fastened by a first end to said object and having the second end in such cooperative relationship to a trip mechanism as to hold said trip mechanism in an inoperative condition; and elongated attachment means having one end attached to said arming wire or cable for sliding movement therewith, the other end protruding from said slotted sleeve and having means on the other end for fastening to said second object whereby: when said objects are separated said arming wire or cable will be forcibly extracted from said sleeve and said second end of said wire or cable will be withdrawn from cooperation with said trip mechanism the slot in said sleeve being normally sufficiently closed to confine said wire or cable such that a predetermined force is needed to pull said wire or cable from said slot when force is applied by pulling on said attachment and said plastic sleeve being sufficiently flexible that said attachment may be moved on said wire or cable along the slot; so that said attachment may easily be positioned at any point along said sleeve.

Claim 4
Dependent Claim
20 words
