Description
The Fuze No. 848 Mk V consists of a vane assembly, throat and upper fuze body, and lower fuze body and base piece. There are ten small vanes of sheet steel attached to the vane hub, to which is also attached the arming spindle. A ring soldered to three clips is located around the vanes to prevent damage to the vanes and to hold the vane cap on. The spindle threads down into the throat and holds down a brass retaining cap or ball-release cap. The retaining cap holds two retaining balls in grooves in the upper part of the striker, which is spring-loaded down. A safety pin passes through the throat and the striker. In the lower part of the throat is the primer, which flashes down to a delay train housed in the lower fuze body. The base plug, which houses the magazine, is attached to the lower fuze body.
The delays, housed in capsules, vary from 4.0 to 32.5 seconds, depending on the capsule used.
The Fuze No. 848 Mk IV differs from the Mk V in that instead of the arming spindle holding down the ball retaining cap, it has an arming cone which moves down inside a ball cage and holds the retaining ball out, preventing the ball cage and spring-loaded striker from moving down.
