Definitions

  • Theobject of the present invention is ⁇ to construct an improved multiple action pro ⁇ jectilefuse havin ⁇ 5 a centrifugal member ⁇ for i controlling one o ⁇ the fuse'actions, the conyiii trolling arrangement being characterized by the fact-.that the member situated in the nose i of the fuse and located radially of the proment according to the invention, one being applied ⁇ to a percussion fuse with instantaneous and retarded action and the other to a mechanical fuse operating after a certain "time or on percussion.
