To' all 'whom lit may concern Be it known that I, EUGENE SCHNEIDER,
' said fuse body of Le Creuzot, France, have invented new and useful Improvements in or Relating to Percussion-Fuses, which is fully set forth in4 the following specification.
his invention relates to percussion fuses` and has for its object to provide a percussion fuse such that it does not act until after the projectile has passed through the obstacle that it encounters, no matter lvvhat'the= thickness of this obsta'cle may be. A projectile burst behind the obstacle 'whether the latter be a gun screen, a wall, a ships plate or armor plate. Similarly the. projecattacked directly or after passage through.' a resisting medium such as water.
Accordin to this invention, the fusecomrises a. stri er holder and a priming holder,- th movable in the forward direction under the influence of the impact of theprojectileh with anv obstacle, one of the element-s being held in the displaced position, while the other isfree and bears against the frontend ofthe body ofthe fuse by its inertia. during the retardation of the projectile, this being the condition so long as this retardation continues; the movement for firing takes place after the obstacle has been penetrated, under the. influence'of a spring which-has been' compressed by the' forward movement oiy the element. y
In order that the said invention may be clearlyv understood and readil carried into effect, the'same will now be fully with reference-to the accompanying drawings, in which x Figures 1 and 2 illustrate the fuse 1n sectional elevation, the parts being in two different positions. Fig. 3 is a sectional' plan onthe line 3 3 in Fig. 1. Fig. 4 illustrates a modifiaction, the tow halves of the-ii ure.,
showing the-parts in two different positions.
The two usual elements, that is to say, the striker holder B and the priming holder C are arranged in the fuse body7 A.l In accordance with the invention each of the two elements B and C is movable and they are arranged in such a. manner as' to move in the* same direction under the influence of the shook of the projectile against an obstacle'. With this obj ect, the element B normally bears against the rear end aofthe fuse body,

' i 'while the yother element C Iprovided with this `improved fuse beyond the target,
escribed more, .Y c, the element C is normally' Vheld against an intermedlatepartition a in the bva counter spring bears against the front end a. o the fuse heelement B is provided with. a device which upon the simultaneous displacement of the two elements B and C insures that it shall; stop and remain inthe displaced osi-` tion. For stopping striker holder carries tinuous collar b whic strikesagains't the lower facewof ther-.partition a2 (Fig. 2). Normally segments b embrace a split extensible ring b2 which bythe thrust of its two extremities tends to separate them (Fig. 3). A safety device4 of any known. ln'nd which may,
segments `D united by a' spring al prevents accidental displacement of the element B during transportation. So long asthe segments'D occupy the position shown in Fig. b bearing against their lower 1, the collar face prevents part comes inoperative, the segments any vforward movement ofthe 2. The elements mal position in the fuse body A and only leave this, position when .the projectile. Assoon as an obstacle strikes an obstacle. is encountered, thetwo elements move one in front of the otherI inthe fuse body, and it is only necessary to standing the compression work et the spring immediately becomes accelerated yrelatively to` the, element B'., This element B is sto ped in its forwardv move- .Y e collar b strikes ,againstment as soonf as the partition a (Fig. 2). Furthermore when the lower edge of the segments b has )assed beyond, theshoulder a3 of thefuse force thus locking the cocked position. The ,element C has pre-v viously struck against the front end a. of'
the fuse body. The retarding action. that .a
the projectile exerts the, obstacle struckfby upon the velocity-of the latter constitutes an actual counter-acceleration, the effects of which upon the various elements in movement are proportionate to vtheir masses. It follows that lthe retarding eii'ort exerted Patented sepan', 1915; 7
