Description |
The internal assembly of this fuze is the same as the other R.S.A. models already des-cribed. The distingushing features are the truncated hood and the large diameter. The hood on the dome cover is set down over the regular R.S.A. fuze mechanism. |
At the apex inside the dome, there is a spring which is compressed when the hood is pla-ced on the fuze. Around the base of the hood are three spring loaded detents. The clip fits around the base of the hood and compresses the spring-loaded detents, which are pressed into the A-groove on an adapter which screws into the bomb. |
Operation |
When the bomb is released, the clip is pulled away, releasing the spring-loaded detents, which spring out and fall away. The hood then falls off with the help of the spring. The function of the fuze then is the same as described in the R.S.A. Models 1925, 1928, and 1929. |
Remarks |
The usual markings to indicate the delay are found on the pin at the base of the trunca-ted hood and are as follows: |
White – Instantaneous |
Alternate Black and White – Short delay 0.05 seconds. |
Black – Long delay 0.15 seconds. |
