MECANISME DE TIR A REPETITION.UN AXE LE LONG DUQUEL UN ELEMENT DE DECLENCHEMENT SE DEPLACE EST PERPENDICULAIRE A UN AXE DE PERCUTEUR DE MEME DIRECTION QUE L'AXE DE L'AME DU CANON. LE MECANISME LUI-MEME ET LE MECANISME DE PERCUSSION SONT SEPARES. UN DECLENCHEUR SE TROUVE DANS UN PROLONGEMENT DE L'AXE. UN LEVIER DE TIR EST RELIE DE FACON A POUVOIR ETRE ACTIONNE A UNE MANETTE DE TIR MOBILE. LA DISPOSITION DU MECANISME DE TIR PAR RAPPORT A UN POINT DE REFERENCE D'UN ENSEMBLE DE POINTAGE ET VISEE RV, A L'AFFUT INFERIEUR, A L'AXE DE ROTATION D'UN VOLANT DE POINTAGE LATERAL ET A UN AXE DE PIVOTEMENT DE LA MANETTE DE TIR, DEMEURE INCHANGEE DANS UN DOMAINE DETERMINE DE POSITIONS DU CANON.APPLICATIONS: NOTAMMENT AUX CANONS A REPETITION. There is disclosed a repeating firing system for a weapon with a barrel mounted on a lower gun carriage which is horizontally traversed by the gunner, the barrel being capable of being elevated through a substantial angular range. The system includes a firing device capable of repeated operation which serves to actuate a striker pin device disposed on the barrel of the weapon and serving to initiate the firing of the weapon. The firing system has a firing lever operable by the gunner from his weapon sighting and firing position, the firing lever serving to displace a release element, in opposition to the restoring force of a spring, from a position of rest to a firing position, from which, after the firing lever has been turned to effect the firing operation, it is returned by the restoring force of the spring to the position of rest in order to be ready to repeat the firing operation. The system includes means connecting the firing lever with a manual firing lever mounted on the lower gun carriage at the gunner's position in a fixed position relative to the directional and sighting device for the weapon mounted on the lower gun carriage. In the disclosed embodiment, the means by which the gunner traverses the lower gun carriage is a traversing wheel on such carriage and the pivotal axis of the manual firing lever is coaxial of the traversing wheel and thus remains unchanged with respect to the lower gun carriage for every position of the gun barrel within the angular range through which it may be elevated.
