A fuze includes a conically shaped body having a central longitudinal channel communicating with a rearward central chamber, a firing pin assembly containing a primary and a biased secondary firing pin disposed in the channel, a delay arming assembly disposed in the chamber, a sleeve containing a setback locking assembly disposed in chamber, and a pyrotechnic smoke cartridge located in the hollow of the sleeve. The arming assembly contains two V-shaped pivotable levers held in the safe position by the secondary firing pin extending into a hole in each lever and by a detent pin extending into a hole in the lower lever, each lever having a hole containing a firing ball. On firing the projectile from the gun, the biased detent pin is withdrawn by setback force and the detents on the secondary firing pin are withdrawn by centrifugal force, releasing both levers to pivot by centrifugal force and align the firing balls with the firing pins and the cartridge primer. On ground impact the crush cap collapses, driving the primary firing pin into the secondary firing pin, which impacts the firing balls striking the primer.

An artillery impact fuze for practice or tactical munitions comprising: a conically shaped body having a forward central longitudinal channel communicating with a rearward central chamber; a firing pin assembly disposed in said channel, said firing pin assembly including a primary striker pin, a spring biased secondary striker pin in spaced apart relation rearward of said primary striker pin, and detent means for holding said secondary striker pin to project into a hole in each lever of the arming assembly, said detent means being responsive to centrifugal force to free said secondary striker pin to withdraw from said arming lever holes; an arming assembly disposed in said chamber rearward of said firing pin assembly, said arming assembly including a forward rotatable lever containing a first hole for receiving said secondary striker pin and a second hole containing a firing ball; and a rearward rotatable lever containing a first hole for receiving said secondary striker pin, a second hole containing a firing ball and a third hole for receiving a detent pin of the setback assembly; each lever containing a pivot means, which after withdrawal of said pins from said holes, permits rotation of the lever in response to centrifugal force to the armed position, wherein said firing balls are aligned with said striker pin; a setback assembly disposed in said chamber rearward of said arming assembly, said setback assembly including a first longitudinal channel, a second longitudinal channel, a radial channel connecting said first and second channels, a setback pin and compression spring disposed in said first channel, a detent pin containing an annular groove and a compression spring disposed in said second channel, and a locking ball disposed in the radial channel between said pins and extending into the annular groove for holding the detent pin in said hole in the rear arming lever, said setback pin being responsive to setback force to move rearward to free said locking ball and thereby permit the detent pin to withdraw from from said hole in the rear arming lever; and an explosive composition including a primer disposed in the chamber rearward of the arming assembly, said composition being ignited by impact of the firing balls with said primer by axial movement of the first and second striker pins, the firing balls being placed in axial alignment with the primer and the firing pins by movement of the arming levers of said arming assembly.
