Abstract (en)

[origin: FR2721390A1] The attachment consists of a shell (7) which surrounds the barrel at a distance from it and is the same length as the barrel's projecting section. It comprises a front ring (6) which is fixed to the barrel close to its free end and a rear ring connected to the barrel on a level with its smoke box, and is made from a series of semi-cylindrical sections (8a,8b) assembled by means of connectors. The front and rear (5) rings have grooves (24,28) to receive the semi-cylindrical sections, and each of the connectors is in the form of an H-section bar. Each semi-cylindrical section has an outer (12a) and/or an inner (19) reinforcing element; the outer one has an omega-shaped cross-section, and the inner one a T-section. Holes (13) in the semi-cylindrical sections allow air circulation between the barrel and attachment.
