Title: Nick L. Purcell: Ordnance Venting Inventions
Introduction
Nick L. Purcell is an inventor associated with Ridgecrest, California. His patent work addresses ways to reduce the risk of explosions when ordnance is exposed to fire. He is credited with 2 patents.
Latest Patents
Purcell’s patents describe two ordnance venting devices that use heat-responsive patches to open vents in an ordnance casing.
“ Shearing Type Ordnance Venting Device” describes holes in an ordnance casing covered by metallic patches. Because the patches and casing expand differently when heated, the resulting shearing forces can cause the patches to separate and expose the holes, providing a path for venting.
“Bending Type Ordnance Venting Device” also uses holes covered by patches, but its patches are bimetallic and deform under high temperatures. The patent describes attachment methods such as brazing, soldering, or adhesive bonding.
Career Highlights
Purcell’s listed patents are associated with the United States Navy, represented by the Secretary of the Navy. Both inventions focus on passive, heat-triggered venting intended to reduce the danger of explosions in ordnance items exposed to fires.
Collaborations
Joseph A. Schmidt and John A. O’Malley are identified as Purcell’s coworkers.
Conclusion
Nick L. Purcell’s two ordnance venting patents present complementary approaches—shearing and bending—to opening casing vents under high-temperature conditions and reducing explosion hazards.
