ABSTRACT:
A rammer for artillery shells with a carriage behind the gun's tube that supports a tray in alignment with the powder chamber, that has a mechanism at the rear to intercept the shell, that travels on slides along a track paralleling the axis R of the tube, that is coupled to a piston-and-cylinder drive mechanism to accelerate toward the tube, and that has a braking mechanism to brake it at a prescribed distance from the rear end of the tube. The braking mechanism has a shock absorber position in the longitudinal midplane of the carriage with a piston that moves against the force of a friction spring inside a cylinder and that has a piston rod projecting forward beyond the front of the carriage with a stop mounted on it, whereby the stop rests directly against the rear end of the tube when the carriage is in the forward and braked position.
