Abstract

14,840. Lucas, H., and Jenkins, F. June 27. Inflating. - Relates to two stage tyre-pumps. In co-axial cylinders a, bare pistons c, d provided with leather packings so arranged that the piston c compresses on the upstroke and the piston d on the down-stroke. Holes x are formed in the upper part of the cylinder b, for the passage of air into it from the cylinder a. The cylinders are fixed at their lower ends in a fitting g, pivoted to the foot-pieces and carrying the pressure gauge and delivery nozzle. At the upper end of the cylinders is a cap l, held in place by a nut n, screwing on to a closing-piece o on the cylinder b. The piston-rods q, r are attached to a cross-head t, above which a handle u is mounted, preferably rotatably, on a stem v screwed on to the end of the rod r.
