Definitions
- fionteneur pour nharrre propulsive -can be secured to a container lair
- the field of the present invention is that of containers capable of receiving a propellant charge and more particularly that of containers used in the field of large caliber or tank artillery.
- Modular cylindrical containers which have been made of combustible material have already been defined. Thanks to their rigidity, such containers are easier to use than traditional powder sachets.
- Patent FR9101499 describes a container connecting device which comprises on the one hand a sliding ring and on the other hand hook-and-loop fastening means arranged on a front face of the container. Such a device is complex and expensive to manufacture.
- the invention thus proposes a container comprising simple and inexpensive means making it possible to secure it with a second container at one of its front faces.
- Such a container can be linked quickly and easily with another container according to the invention, the separation of the containers being just as easy.
- the invention therefore relates to a container intended to be made integral with a second container at one of its front faces, and comprising a ring which is slidably mounted at the level of a first constriction, ring being able to slide to partially cover a second constriction arranged on the second container, characterized in that the ring carries a thread arranged on a front end, thread intended to come to engage on a thread integral with the second container.
- the first constriction has an annular collar on which abuts a shoulder arranged at a rear portion of the ring so as to ensure an axial immobilization of the containers when the ring covers the second constriction of the second container.
- the container comprises a sub-ring integral with the first constriction and which carries the annular collar, sub-ring on which the ring is slidably mounted.
- the invention also relates to a container intended to be made integral at one of its front faces with another container, container characterized in that it comprises a second constriction carrying a thread, intended to receive a threaded ring and sliding carried by the other container.
- this container comprises a threaded ring secured to the second constriction.
- the container comprises means ensuring radial positioning with another container.
- the radial positioning means may include a tubular extension intended to be housed in a complementary circular groove carried by another container.
- the radial positioning means may include a circular groove intended to receive an additional tubular extension carried by another container.
- the radial positioning means may comprise a bowl with a frustoconical profile which is placed in the center of the front face, a bowl intended to receive a complementary bulge carried by another container.
- the radial positioning means may also include a bulge with a frustoconical profile which is placed in the center of the front face, a bulge intended to be positioned in a complementary bowl carried by another container.
- the container has a constriction at each of its ends, one of the constrictions carrying a thread and the other carrying a threaded sliding ring.
- the various components: ring, ring or sub-ring will preferably be made of plastic material of the high density polyethylene or polyamide type.
- FIG. 1 represents in partial section and before their joining, two containers according to a first embodiment of the invention
- FIG. 2 shows the same two containers after joining
- FIG. 3 represents in partial section and before their joining, two containers according to a second embodiment of the invention
- FIG. 4 shows the same two containers after joining
- FIG. 5 shows a modular container according to the invention.
- a first container 1a is intended to be made integral with a second container 1b at its front face 2a. The latter will then be in contact with the front face 2b of the second container.
- Each container comprises a cylindrical envelope 3a, 3b made of a combustible material such as nitrocellulose, cardboard or a cardboard / nitrocellulose mixture.
- the envelopes are closed by end caps 4a, 4b which are also made of combustible material.
- the plugs are made integral with the envelopes by gluing at the level of the cylindrical surfaces 5a,
- the containers 1a and 1b are shown here partially. They are intended to receive a propellant charge in grains or sticks (not shown).
- the container 1b carries at its other end a projectile (not shown) which will be made integral with the casing 2 by a connecting ring (for example similar to that described by patent FR8712484).
- the container carries at its other end a base (not shown) provided with an igniter tube (see for example patent FR9101499 which shows the fixing of such a base on one envelope).
- the stopper 4b carries a bowl 6 with a frustoconical profile which is placed in the center of the front face 2b.
- the stopper 4a carries a bulge 7 with a frustoconical profile which is arranged in the center of the front face 2a.
- Axial openings 22a and 22b are arranged at the front faces 2a and 2b of the containers. These openings facilitate the transmission of flame from one container to another when the propellant charge is ignited. They are closed in a known manner by means of combustible sheets (not shown here).
- the end plugs 4a and 4b each carry a constriction 8a, 8b, the maximum diameter D1 of which is less by the order of 10mm than the external diameter D2 of the container.
- the constriction 8a of the container 1a (hereinafter called the first constriction) carries a sub-ring 9 fixed for example by gluing.
- This sub-ring is made of plastic, for example of the high density polyethylene or polyamide type.
- the sub-ring 9 carries on its external cylindrical surface 10 an annular flange 11.
- a ring 12 is slidably mounted on the sub-ring 9.
- the ring 12 is also made of plastic material of the high density polyethylene or polyamide type.
- the ring has a shoulder 14 arranged at a rear part 13.
- the ring also has a tapping 16 at its front end 15.
- the internal thread 16 has a diameter greater than the external diameter of the sub-ring 9, which allows the sliding of the ring on the sub-ring.
- the shoulder 14 is intended to come into abutment on the flange 11 so as to come to axially limit the movement of the ring relative to the sub-ring. From the mounting point of view, the ring is placed on the sub-ring before gluing the latter on the first constriction 8a. Thus the ring 12 can no longer be separated from the container 1a, which avoids its loss and simplifies the logistics.
- the ring 12 When positioned on the sub-ring 9, the ring 12 has an external diameter D3 which is less than or equal to that (D2) of the container. Thus the ring 12 does not interfere with the placing of the container in the chamber of a weapon.
- the container 1b carries on its neck 8b (hereinafter called the second neck) a ring 17 fixed for example by gluing.
- This ring is also made of plastic, for example of the high density polyethylene or polyamide type.
- the ring 17 carries a thread 18 which is intended to receive the internal thread 16 of the ring 12.
- FIG. 2 represents the two containers 1a and 1b assembled by the ring 12.
- the containers were brought into contact with each other, at their end faces 2a, 2b.
- the bowl 6 and the bulge 7 then ensure the alignment of the containers.
- the bowl and the bulge thus constitute means ensuring a good relative radial positioning of the two containers.
- the ring 12 being able to slide and rotate freely relative to the sub-ring 9, its internal thread 16 can easily engage on the thread 18. It is therefore not necessary to angularly index a container relative to the other before making them integral by means of the ring 12.
- the ring 12 is screwed onto the ring 17 until its shoulder 14 abuts on the flange 11 of the sub-ring 9.
- the flange 11 thus ensures the axial immobilization of the containers 1a and 1b when the ring covers the second narrows 8b from the second container.
- the dimensions of the ring, the sub-ring and the ring will be defined so that this axial immobilization can be achieved.
- the ring 12 before coming into abutment, can translate with respect to the first constriction 8a of a length less than or equal to the length of the second constriction 8b of the second container 1b which it must cover.
- the first constriction 8a will be given a length twice that of the second constriction 8b, and the ring 12 and its sub-ring 9 will also be given a length twice that of the ring 17.
- the flange 11 will be placed so to allow sliding of the ring equal to half its length.
- the material of the ring, the sub-ring and the ring fragments when the propellant charge is ignited under the effect of the gas pressure.
- zones of embrittlement obtained for example by localized heating or by machining.
- the separation of the two containers is easily and quickly obtained by unscrewing the ring 12 from the ring 17.
- Figures 3 and 4 show containers according to a second embodiment of the invention.
- the front faces 2a and 2b of these containers are flat and therefore do not have a bowl or bulge.
- the threaded ring 17 carried by the container 1b has a tubular extension 19 with an external diameter smaller than that of the ring.
- the sub-ring 9 has at its front part a counterbore 20 which defines with the first constriction 8a a circular groove 21.
- the groove 21 is intended to receive the tubular extension 19, it therefore has a width equal to the thickness of the extension 19.
- Chamfers are arranged so as to facilitate the mounting of the extension 19 in the groove 21.
- FIG. 4 shows the containers in Figure 3 after assembly.
- the groove 21 and the tubular extension 19 constitute the means ensuring good relative radial positioning of the two containers. They thus ensure the function which was fulfilled in the embodiment previously described by the bowl and the bulge arranged on the front faces of the containers.
- Such an embodiment simplifies the manufacture of the containers by making it possible to produce flat front faces. It also ensures a more rigid radial positioning which facilitates the screwing of the ring on the ring.
- FIG. 5 represents a modular type container according to the invention.
- This container made of combustible material, is intended to be assembled with other containers which are completely identical to it in order to constitute a propellant artillery charge. It is shown here in half-view / half-section, the upper part being cut axially and the lower part being shown in external view.
- It consists of a combustible envelope 3, closed at one end by a plug 4a which carries a first constriction 8a and at the other end by a plug 4b carrying a second constriction 8b.
- the first constriction 8a carries a sub-ring 9 and a ring 12, the second constriction 8b carries a ring 17.
- the sub-ring 9 has a countersink 20 defining a circular groove 21, the ring 17 has a tubular extension 19.
- the combustible envelope would then be closed at its ends by plugs 4a, 4b of the type of those represented in FIG. 1.
- the cylindrical envelope was closed by two combustible plugs carrying a constriction .
- the envelope is shaped in an appropriate mold. This avoids a delicate operation of fixing by gluing the plug on the envelope.
- tubular extension will be integral with the plug and / or the circular groove will be fitted in the plug.
- plug and ring or plug and sub-ring constitute a single piece.
- weakening zones may be provided on the latter, obtained for example by localized heating or by machining.
