Abstract: A flick rammer for artillery rounds. The rammer has a loading tray that is positioned in alignment with the powder chamber at a prescribed distance to the rear of the gun. The tray accommodates the round. The rammer also has a mechanical acceleration component that engages the rear of the round and is connected to a cylinder-type drive mechanism. To improve the device to the extent that ramming will remain rapid whereas the design will be simple enough to operate reliably even at light loads and to occupy very little space, the cylinder-type drive mechanism is a pneumatic cylinder that communicates with a compressed-air reservoir through a rapid-opening control valve, and the mechanical acceleration component is connected to the moving component of the pneumatic cylinder through a stroke-transmission mechanism with a transmission ratio greater than 1.
