Application filed February 5, 1924;. Serial No 690,814.

To all whom it may concern:

Be it known that I, LEON EMILE Ri l- MOICDY, a citizen of the Republic of France, resident of Paris, France, have invented new and useful Improvements in Apparatus for Transmitting the Firing to the Charge in Projectiles of Elongated Shape, which is fully set forth in the following specification.

The present invention has for its object a mode of application of the type of fuse described and illustrated in U. S. Patent No. 1359,0755, to projectiles in which the nose or front part is greatly elongated either by reason of the actual shape of the projectile or by the addition to the latter of an extension or of a ballistic cap. According to the invention, a tubular axial conduit is provided in the elongated projectile proper, the extension or ballistic cap, as the case may be, and this conduit is provided at its forward extremity with a primary fuse constructed to operate in accordance with the aforementioned patent, that is, by rammingin and inertia, which fuse transmits the firing action to one or several similar or relay fuses, the last fuse of the series being the normal fuse of the projectile and being also arranged so as to operate by ramming-in, or preferably by ramming-in and inertia.

According to one practical form of construction ofthe invention, the primary fuse at the head, which transmits the firing to the relay fuses and to the normal fuse, may be housed in a removable tube which, for example by the simple fitting of its rear extremity, can be fined or secured on or within the nose of the projectile proper, for example on or in the fuse carrier of the latter.

In all cases besides the auxiliary front fuse, the arrangement comprises the normal percussion system for ignition of the charge, the operation of this latter system by ranr ining-in and inertia being assured by the pressure of the gases or by the firing of the initial fuse, without the interposition of any auxiliary powder charge, either directly or through the intermediary of one or several similar relay fuses.

Various constructional forms of the invention are represented for sake of example in the accompanying drawings, in which Fig. 1 shows in sectional elevation the application of the invention to a projectile is housed the normal fuse C whose opera tion causes the firing of the charge. This fuse is adapted to operate by ramming-in and inertia, and to secure this effect should be arranged as described in my Patent No. 1,459,07 5 aforesaid, that isto say, so as to operate by rannning-in of a movable carriage containing the entire firing mechanism, said ramming-in being brought about by the simple destruction of a retaining means such as a pin and being adapted to cause one of the elements of the mechanismwhich is free in the said carriage to be projected by inertia upon the other element which is rigidly connected with said carriage.

an elongated supplementary tubular part D which serves at its outer part as a housing for an initial front or primary fuse which is preferably of the type shown and described in my aforementioned patent. That is to say,-said primary fuse should comprise a movable carriage G which is secured upon the tubular extension D, for example by means of a pin 9, said movable carrier containing the whole of the firing mechanism, to wit, a striker G rigidly connected to the envelope or carriage G, a priming cap G freely mounted in the envelope or carriage, a separating spring G and a washer with its projections G* immovably held to the rear of an abutment d of the tube D, the ramming-in of the carriage being rendered possible by the sliding of the slots G of the envelope upon the projections of said washer G The supplemental tubular part D is preferably made removable, its lower extremity D being arranged in such a manner as to be capable of being secured to the fuse carrier or to any other part of the fuse proper by screw-threads, a bayonet-joint, or any other suitable retaining means. This arrangement allows at will the firing of the projectile either with or without the extension, this lat- In the example of Fig. 1, there is provided v ter comprising a firing mechanism which coacts with the normal striker of the projectile when the supplementary part in question is utilized. It will-be seen that the shock of a projectile provided with such an extension, or the collision of this projection with an obstacle, however feeble it may be, instantly. causes the operation of the extra-sensitive;

front or primary fuse Gby ramming-in and inertia. The firing of this fuse is transmit ted to the normal fuse G which operates likewise'by being rammed-in under the pressure of the gases and inertia,the carriage 0 being driven toward the interior of the projectile,

' shearing the retaining pin 0 and causing the .ignition'of the prlming cap of the fuse C ample of the application of the invention to a projectile provided with a ballistic cap.

I The cap E can be secured in any suitable way, as-by a disk Ebetween the body ofthe projectile and the fuse carrier B. The forward end of the ballistic cap E is secured to the tube D in any suitable manner, such screw-threads, bayonet-joint or otherwise, and the tube B is simply fitted at its rear e1:- tremity in the fuse carrier B as shown.

As in the example of Fig. 1, the tube I) is arranged to receive the initial or primary fuse Grand the intermediary or relay fuse or fuses between the primary fuse and the normal fuse C.

' Having thus particularly described and ascertained the nature of mysaid invention and the manner in which the same is to be performed, what I claim is l. A projectile provided with a forwardly extendin tubular member, and a plurality of fuses arranged in said tubular member one in front of another, each of said fuses being operable only by ramming-in and in ertia, whereby each fuse upon operation will actuate the one next in its rear.

2. A projectile provided with a gas-directing forwardly extending tubular member, and a plurality of fuses 111 said member one in front of another, each of said fuses being operable only by ramming-in and inertia, whereby the gases of explosion of each fuse will actuate the fuse immediately in its rear. 3. A projectile, a fuse carrier mounted in the nose thereof, a ballistic cap secured to the forward end of the projectile, a tubular member extending from said fuse carrier to the forward part of said cap, a ramming-in and inertia actuated fuse in said carrier and a similar fuse in said tubular member forward of said first-mentioned fuse. I In testimony wl'iereof I have signed this specification.
