Abstract

A projectile launching apparatus for cleaning the inner surface of a tube by forcing a projectile through the tube, comprising: a main body containing a breech chamber terminating in an exit port, wherein the breech chamber is provided with a loading port in a side thereof for radially loading a projectile into the breech chamber; a slide disposed on an exterior surface of the main body, the slide being axially movable between a first position wherein the loading port is exposed for loading of a projectile into the breech chamber and a second position wherein the loading port and the breech chamber are sealed; a gas gun operatively connected to the main body in pneumatic communication with the breech chamber; and an exit nozzle connected to the exit port and being connectable to a first end of the tube to be cleaned.

Dependent claims

A method comprising:

providing an apparatus to a user, wherein the apparatus includes a body, a slide, and a gas gun, wherein the body includes a first end portion and a second end portion, wherein the first end portion is configured for connecting to the gas gun, wherein the second end portion is configured for connecting a tube end portion, wherein the body includes a breech chamber extending between the first end portion and the second end portion, wherein the breech chamber includes a port extending between the first end portion and the second end portion, wherein the slide is configured for moving over the body external to the breech chamber between the first end portion and the second end portion such that the slide is configured to move between an open position and a closed position, wherein the open position has the port uncovered via the slide, wherein the closed position has the port covered via the slide;
and
enabling the user to:
couple the second end portion to the tube end portion;
insert a projectile into the breech chamber via the port based on the slide being in the open position;
move the slide from the open position to the closed position;
and
activate the gas gun based on the body extending between the gas gun and the tube end portion while the first end portion is connected to the gas gun such that the projectile moves from the breech chamber into the tube end portion while the slide is in the closed position.
