Title: Thomas A Cammack: Innovator in Projectile Fuze Technology

Introduction

Thomas A Cammack is a notable inventor based in Beltsville, MD (US). He has made significant contributions to the field of projectile fuze technology, holding a total of 3 patents. His work focuses on creating reliable and cost-effective solutions for military applications.

Latest Patents

Cammack's latest patents include a "Small caliber fuze with arming delay, second impact and graze sensitivity." The objectives of this invention are to provide simple, reliable, and low-cost mechanical means to achieve second impact detonation and substantial safe arming separation from the gun for point detonating fuzes for small caliber spin stabilized shells. The first objective is attained by using a heavy shield over the firing pin, which is removable between the first and second impacts by spin forces. The second objective is achieved by a centrifugally driven rotor that contains the out-of-line explosive element, deforming a ductile material to effect the arming delay.

Another significant patent is the "Flywheel type odometer safing and arming mechanism." This fail-safe projectile fuze safety-and-arming mechanism comprises a rotor that carries an explosive train component, with its mass center aligned on the projectile spin axis. Fixedly secured to the rotor is a pinion that engages first and second drive gears, which have clearance spaces on their circumference. The mass centers of the drive gears are offset from their geometric centers, allowing for continuous engagement but intermittent interaction with the pinion due to the clearance spaces. This design ensures a constant, predetermined arming distance for selected projectile launchers, regardless of the linear velocity of the projectile.
