ABSTRACT:
A device for swabbing artillery cannon chambers, obturators and the like. e device includes a cylinder for holding a fluid such as water and also has a gas pressure source such as a hand operated air pump for placing the fluid in the cylinder under a positive pressure. The gas pressure or air pressure is adjustably controllable. Also included is a tube extension in communication with the cylinder to receive the fluid under slight pressure. The tube extension includes a valve for controllably introducing water under pressure into the tube extension. A sponge is mounted on the other end of the tube so as to absorb water through the tube to wet the sponge. The device is controlled with a handle on the cylinder to permit insertion and removal of the sponge into a cannon chamber while the sponge contains some of the fluid. The hand operable pump is axially centered about the axis of the cylinder for adding air pressure in the cylinder. In a preferred embodiment, the handle is toroid shaped and the hand operable pump is positioned inside the toroid shaped handle to permit pumping while holding toroid shaped grip. The sponge is preferably removably mounted for replacement as needed because of wear or damage.
