2428. Rugg, L. H. Jan. 31. Pistons of internal-combustion engines are packed by asbestos cup-leathers B. The asbestos may have a rubber core or may have wire-gauze embedded in it, and may have a metallic facing. The ring may be treated with lubricant, or graphite or other lubricant may be incorporated in it. The cup-leather is secured by a disk or annulus C, which may be of smaller diameter than the cupleather, or may be recessed and perforated to permit the gases to act on the leather. The piston may have two cup-leathers, one directed towards the front and the other towards the back end of the cylinder.
