[Class 122 (i)] In a small hand pump of the type that is fitted to a container and liquid is drawn through a valve in the pump cylinder and delivered through the tube d that forms the piston-rod, the piston is formed of discs c of cork, leather, &c. gripped between nuts h, j. The underside of the nut h, which is screwed hard on to the rod, is provided with recesses or projections i against which the upper disc c is pressed by the lower, nut j so that the piston can be rotated without unscrewing the nuts.
