Abstract: The invention relates to a retaining device for retaining the crane of a revolver, said device being intended to provide longitudinal locking between the crane and the revolver crane while still allowing said crane to be released for dismantling purposes. According to the invention, a stopper (42) is slidably mounted inside the crane (3), said stopper having an end (44) projecting downwardly from the crane (3) in order to engage in an associated groove (47) provided in the frame (2) of the revolver. The stopper (42) is laterally accessible in part via an oblong slot (18) in the crane (3), thereby enabling said crane to be released by means of an elongate tool which retracts the end (44) of the sliding stopper (42). The invention is applicable to revolvers.

Abstract: A locking device is provided for holding the crane (3) in its closed position by means of a pushbutton (14) and a sliding latch (15) mounted in the crane (3). The pushbutton (14) is laterally accessible from the side of the gun opposite to the side from which the cylinder (4) is swung out, and the pushbutton co-operates directly with the sliding latch (15) in order to retract its end that is normally received in an associated notch provided in the frame (2) of the revolver. The pushbutton device (14) thus makes it possible to unlock the crane (3) using the same hand as is used to push the cylinder (4) towards its open position, and this is highly advantageous on ergonomic grounds. The invention is applicable to revolver manufacture.

Abstract: A device for supporting the mechanism of a revolver in association with the frame of the revolver. The device is constituted by a mechanism carrier plate (1) which directly receives the various subassemblies (4, 13, 24, 30, 35) of the mechanism, and which is capable of being mounted directly, together with the subassemblies supported thereby, on the frame (2) of the revolver.
