The invention relates to an arrangement for supporting a shell (1) into the barrel of a breech-loading weapon and to a support member for supporting a shell. The arrangement comprises a flanged support element (5), to which a fastening element is connected with threads. A sleeve-like clamping element is arranged around the fastening element. Both have grooves for tail fins of the shell (1). The support member (5) has a support element, to which a fastening element is connected with threads and on top of which a sleeve-like support element is arranged.

1. An arrangement for supporting a shell into the barrel of a breech-loading weapon, the arrangement comprising a support member to be fastened to a shell tail, the support member comprising: a support element provided with a rim flange;a fastening device configured to fasten the support element to the shell tail;a firing member in the support element for firing the actual primer of the shell for firing the shell,wherein the fastening device comprises a sleeve-like fastening element having grooves for the tail fins of the shell and, between the grooves, jaws settling onto the shell tail tube, the outer surfaces of the jaws being outwardly bevelled at least up to the ends of the jaws, andwherein the fastening element and the support element are provided with matching threads in such a manner that rotating them relative to one another changes their axial position relative to one another; anda sleeve-like clamping element placed around the fastening element and comprising grooves for the tail fins of the shell and able to move in the axial direction thereof relative to the fastening element,whereby rotating the support element relative to the fastening element in such a manner that the support element shifts towards the fastening element, the support element at the same time pushing the clamping element in the same direction in such a manner that the clamping element is pushed along the outwardly bevelled surfaces of the jaws of the fastening element and presses the jaws of the fastening element to the shell tail. 2. An arrangement as claimed in claim 1, wherein the jaws of the fastening element are provided with tips facing towards the shell tail tube, which are forced towards the shell tail tube as the clamping element is forced onto the jaws. 3. An arrangement as claimed in claim 2, wherein the tips of the jaws of the fastening element are provided with rifles or other corresponding projections, which penetrate at least partly into the shell tail tube as the clamping element is forced onto the jaws. 4. An arrangement as claimed in claim 1, wherein the inner surfaces of the jaws of the fastening element are outwardly bevelled away from the support element and that the inner surfaces of the jaws are provided with rifles or other corresponding projections, which penetrate at least partly into the shell tail tube as the clamping element is forced onto the jaws. 5. An arrangement as claimed in any one of claims 1 to 4, wherein the inner surface of the clamping element is outwardly bevelled at least at its end on the side of the jaws of the fastening element. 6. An arrangement as claimed in claim 5, wherein the bevelled surfaces of both the fastening element and the clamping element are parts of a cone. 7. An arrangement as claimed in claim 5, wherein the grooves of the fastening element are dimensioned to settle against the rear surface of the tail fins of the shell during the mounting of the fastening element. 8. An arrangement as claimed in claim 7, wherein the fastening element and the support element have mating surfaces that, when coming into contact with each other, stop a movement between the fastening element and the support element in the axial direction, whereby the position of the clamping element relative to the fastening element is always the same at the end of the mounting and the clamping force to the shell tail is thus substantially constant. 9. An arrangement as claimed in any one of claims 1 to 4, wherein the grooves of the fastening element are dimensioned to settle against the rear surface of the tail fins of the shell during the mounting of the fastening element. 10. An arrangement as claimed in claim 9, wherein the fastening element and the support element have mating surfaces that, when coming into contact with each other, stop a movement between the fastening element and the support element in the axial direction, whereby the position of the clamping element relative to the fastening element is always the same at the end of the mounting and the clamping force to the shell tail is thus substantially constant. 11. A support member to be fastened to a shell tail for supporting a shell into the barrel of a breech-loading weapon, comprising: a support element provided with a rim flange;a fastening device configured to fasten the support element to the shell tail;a firing member in the support element for firing the actual primer of the shell for firing the shell,wherein the fastening device comprises a sleeve-like fastening element having grooves for the tail fins of the shell and, between the grooves, jaws settling onto the shell tail tube, the outer surfaces of the jaws being outwardly bevelled at least up to the ends of the jaws, andwherein the fastening element and the support element are provided with matching threads in such a manner that rotating them relative to one another changes their axial position relative to one another; anda sleeve-like clamping element placed around the fastening element and comprising grooves for the tail fins of the shell and able to move in the axial direction thereof relative to the fastening element,whereby rotating the support element relative to the fastening element in such a manner that the support element shifts towards the fastening element, the support element at the same time pushing the clamping element in the same direction in such a manner that the clamping element is pushed along the outwardly bevelled surfaces of the jaws of the fastening element and presses the jaws of the fastening element to the shell tail. 12. A support member as claimed in claim 11, wherein the jaws of the fastening element have tips facing towards the shell tail tube and are forced towards the shell tail tube when the clamping element is forced onto the jaws. 13. A support member as claimed in claim 12, wherein the tips of the jaws of the fastening element are provided with rifles or other corresponding projections, which penetrate at least partly into the shell tail tube. 14. A support member as claimed in claim 11, wherein inner surfaces of the jaws of the fastening element are outwardly bevelled away from the support element and that the inner surfaces of the jaws are provided with rifles or other corresponding projections, which penetrate at least partly into the shell tail tube when the clamping element is forced onto the jaws. 15. A support member as claimed in any one of claims 11 to 14, wherein the inner surface of the clamping element is outwardly bevelled at least at the end thereof on the side of the jaws of the fastening element. 16. A support member as claimed in claim 15, wherein the bevelled surfaces of both the fastening element and the clamping element are parts of a cone. 17. A support member as claimed in claim 15, wherein the grooves of the fastening element are dimensioned to settle against the rear surface of the tail fins of the shell during the mounting of the fastening element. 18. A support member as claimed in claim 17, wherein the fastening element and the support element have mating surfaces that, when coming into contact with each other, stop a movement between the fastening element and the support element in the axial direction, whereby the position of the clamping element relative to the fastening element is always the same at the end of the mounting and the clamping force to the shell tail is thus substantially constant. 19. A support member as claimed in any one of claims 11 to 14, wherein that the grooves of the fastening element are dimensioned to settle against the rear surface of the tail fins of the shell during the mounting of the fastening element. 20. A support member as claimed in claim 19, wherein the fastening element and the support element have mating surfaces that, when coming into contact with each other, stop a movement between the fastening element and the support element in the axial direction, whereby the position of the clamping element relative to the fastening element is always the same at the end of the mounting and the clamping force to the shell tail is thus substantially constant.
