| Description |
|
The No. 9 and No. 10 are similar in operation. The only difference between them is that the No. 10 Fuze has a longer delay. The protion of the fuze which protrudes from the bomb is cone-shaped. A ring clip is inserted between the fuze body and the vanes. The clip retains the two steel balls which fit in the depression of the arming spindle. The stri-ker spindle is attached to the arming spindle by a pin. The detonator is held back by a creep spring. The fuze body is threaded immediately beneath the cone to thread into the bomb-fuze pocket. The bas eof the fuze is threaded to receive the booster and delay element. |
| Operation |
|
The safety clip is withdrawn upon releasing from the plane. This releases the steel balls, which fall out, permitting the rotation of the arming spindle and vanes to lower the stri-ker until it recesses on the shoulder in the lower part of the fuze. On impact, the deto-nator overcomes the creep spring and hits the striker. |
