the tape is kept tightly around the fuse holder until the set-back pin is automatically pushed back by air pressure when the shell is fired, whereby its two ends are caused to become disengaged from the two lugsformed on the loose bracket, thus permitting the tape to unwind itself from the fuse holder duringthe flight of the shell and to drop away from the latter, together with the safety member 7' attached thereto and the loose. bracket 0.
An ordinar safety-pin 7' provided with a cord 1' for acilitating its removal is inserted into the set-back pin in such a position that the lug 9 should lie between the safety pin 1* and the small cross-pin n on the set-back pin, thereby preventing the set-. ;back pin from beingreleased, as hereinbe fore described, until the safety-pin has been removed therefrom.
Another feature ofthe invention consists in the provision of a vane s on the exterior of a'sleeve Z5v provided aroundthe fuse holder 6 between the latter and the loose bracket 0 above referred to, the sleeve being formed with a hole t to permitthe insertion of the safety member into the fuse holder. This sleeve and vane arrangement is provided with the object of preventing the entrance of earth, water,or, other'foreign substance into the interior of the ,fuse after the tape, together with the safety member attached thereto, havedropped away fromthe shell, this being vefi'ected by-the vane sbeing acted upon by air pressure during the flight of the shell, thereby rotating the sleeve t around the fuse holder, thus causingthe latter to cover the hole-in the fuse holder. The
vane s is preferably made springy and put under tension by the tape, soas to assist in sthe throwing out of the safety member either directly or through the intermediary -of.the1bracket 0 referredto when'the tensionzthereon is released upon the unwinding of .the tape when the shell is discharged. The Vane s"may be attached to the sleeve 25 V bycutting and bending out a strip t in the sleeve tandbyinserting the-end s =between the sleeve, andthe said strip and bending it OVOIrthG latter as shown at s I wish it torbe understooddghat the various features of construction referred to may be anodified without departing fromvthe spirit of the invention. r
