Abstract

13,587. Proschinsky, A. June 2. Inflating bicycle tyres, pumps for. The improvements are shown in connection with a pump in which the piston-rod b forms a second barrel with a piston-rod b<1>. The pistons are packed with leathers f, and projections i on the pistons or covers g preventtheleathers from coming in contact with them. The piston-rods are guided by broad bands of crimped sheet metal d placed in the barrel, which allow the air to pass them. The interior m of the rod b<1> serves as a receptacle for the cyclist's repairing- outfit; it is closed by a cap l.
