Title: Innovations by William J Andrews

Introduction

William J Andrews is a notable inventor based in Tampa, FL (US). He has made significant contributions to the field of ammunition technology, holding a total of 4 patents. His work focuses on enhancing safety and visibility in projectile training and grenade mechanisms.

Latest Patents

One of his latest patents is for a flash output for projectile training. This invention involves an ammunition training round with a crushable nose section that features a flash system. This system makes the impact more visible to users, whether in the air or on land, when the round hits a ground target. Instead of a traditional fuze ignition, the flash system utilizes incendiary energetic pellets that burst into flames upon impact. The design includes a nose area with a lower plastic plug and an upper fuze ogive containing ignition pellets. When the round impacts the ground at an angle, the upper portion snaps off, exposing the ignition pellets to ignite from the impact.

Another significant patent by Andrews is a dual safety fuze for grenades. This hand grenade fuze incorporates a secondary safety feature in the form of a trigger pin inserted through the striker lever. One end of the trigger pin has an undercut portion, while a slide bar within the fuze body has a keyhole opening for engaging the undercut portion. A trigger is connected to the slide bar and is rotatably fixed to the fuze body. A spring biases the trigger away from the fuze body. When the trigger is depressed, the slide bar translates and releases the trigger pin, which in turn releases the restraint on the striker lever.
