Swivel type through bulkhead initiator

Claim 2

A through bulkhead initiator comprising: a donor charge, an acceptor charge, and a full circle swivel assembly including a swivel sleeve and an initiator body, said swivel sleeve containing said donor charge, said initiator body having a cavity formed therein with a sealing barrier at one end, the wall of at least a portion of said cavity adjacent said barrier being cylindrical and having a substantially uniform cross section, said acceptor charge being contained within said portion of said cavity, said swivel sleeve being positioned, with respect to said body, in surrounding relation with said portion of said cavity.

Claim 3

An initiator as defined in claim 1 wherein said swivel sleeve has a wall forming an inner bore having a cylindrical surface, and said donor charge is contained in said wall substantially flush with said cylindrical surface of said bore.

Claim 4

An initiator as defined in claim 2 further including, a detonating fuze, an ordnance transfer line having an end, said end containing said fuze, and attachment means for attaching said end of said ordnance transfer line to the wall of said swivel sleeve with said fuze in communicating relation with said donor charge.

Claim 5

An initiator as defined by claim 3 wherein said attachment means comprises, a sleeve fitting integrally formed with said swivel sleeve, a connector adapter fitting, and a flexible locking nut, said connector adapter fitting having first and second ends with a screw thread formed on each end, said sleeve fitting having a screw thread adapted for engagement with the screw thread at the second end of said adapter connector fitting, said flexible locking nut having a screw thread adapted for engagement with the screw thread at the first end of said adapter connector fitting and being disposed in embracing relation with the end of said ordnance transfer line whereby effecting threaded engagement of said adapter connector fitting with said locking nut attaches and retains the end of said ordnance transfer line in engagement with said locking nut and engagement of said adapter connector fitting with said sleeve fitting connects said ordnance transfer line to said swivel sleeve.

Claim 6

An initiator as defined in claim 1 further including an output charge contained in said cavity in communication with said acceptor charge.

Claim 7

An initiator as defined in claim 5 wherein said acceptor charge is positioned in said cavity between said charge and said barrier.

Claim 8

An initiator as defined in claim 6 including attachment means on said initiator body at a position remote from said barrier for attaching said initiator to and placing said cavity in communicating relation with an ordnance device to be activated.

Claim 9

An initiator as defined in claim 7 wherein each of said donor and acceptor charges comprise PETN.

Claim 10

An initiator as defined in claim 7 wherein each of said donor and acceptor charges comprise HNS.

Claim 11

An initiator as defined in claim 7 wherein each of said donor and acceptor charges comprise RDX.
