Description

Najdluzszy czas trwania patentu do 13 wrzesnia 1947 r« Niniejszy wynalazek dotyczy bezpiecz¬ nika zapalnika opisanego w patencie Nr 16882 i ma na celu jego udoskonalenie, szczególniej zas dotyczy dajacej sie prze¬ suwac tulejki, która po przesuwie i ukon¬ czeniu ruchu uwalnia narzady zabezpiecza¬ jace zapalnik.Wedlug niniejszego wynalazku zapal¬ nik posiada kilka, przynajmniej dwie tulej¬ ki, np. tulejke glówna / i dodatkowa 2, po¬ zostajace pod naciskiem wspólnej sprezyny 3 (fig. 1). Ze wzgledu na to, ze po przesu¬ wie nadól tulejki 1 (fig. 2) tulejka dodat¬ kowa 2 musi sama dalej przezwyciezac o- pór sprezyny 3, aby uwolnic narzad 4 przy¬ trzymujacy tulejke 1, sprezyna musi byc stosunkowo slaba, przyczem to nie moze byc uwazane za brak bezpieczenstwa przy transporcie. Przy przesuwie tulejki w po¬ lozenie odbezpieczone (fig. 3) sprezyna 3 musi przesunac stosunkowo wielka mase obydwóch tulejek 1 i 2, wskutek czego czastrwania odbezpieczania jest stosunkowo dlugi, pomijajac opózniajacy moment po¬ czatkowy. PLThe longest term of the patent until September 13, 1947. The present invention relates to the fuse of the fuse described in the patent No. 16882 and aims to improve it, more particularly it concerns a movable sleeve, which releases the devices after the movement and the end of the movement. According to the present invention, the fuze has several, at least two, bushings, for example a main bushing and an additional bushing 2, under the pressure of a common spring 3 (FIG. 1). Due to the fact that after moving the sleeve 1 (Fig. 2), the additional sleeve 2 must itself further overcome the thrust of the spring 3 in order to free the tool 4 holding the sleeve 1, the spring must be relatively weak, it cannot be considered a safety failure in transportation. On displacement of the sleeve into the unlocked position (FIG. 3), the spring 3 must move a relatively large mass of both sleeves 1 and 2, so that the deprotection period is relatively long, ignoring the delayed initial moment.

Claims

1. Claims, 1, Fuse fuse according to patent No. 16882, in which the inertia securing devices are held in a securing position by means of a sleeve released upon shock when fired, characterized by having two or more sleeves under operation a common spring, of which the outer or outer sleeve protects the inner sleeve from displacement, preventing the ball protecting it from falling out.

2. The fuse of the fuse according to claim 1, characterized by the fact that the inner sleeve is longer than the outer sleeve and has a long channel in which the ball securing it can be slid, so that when a shock is fired it stops earlier from the outer tube, which then eventually it overcomes the resistance of the spring and unlocks it.

3. The fuse of the fuse according to claim 1 and 2, characterized by a weak spring, whereby the forward movement of the two bushings is slow after the positive acceleration effect on the projectile ceases.
