Abstract

997,662. Inflators. BLUEMEL BROS. Ltd. Jan. 15, 1962 [Jan. 16, 1961; Feb. 23, 1961], Nos. 1689/61 and 6589/61. Heading F1N. [Also in Division F2] An inflator for cycle tyres comprises a barrel 10 and a plunger rod 11, the rod being formed from a metal strip bent to tubular form, so that the rod has a slit 14 along its length, and the rod has secured thereto a washer 13 having a recess 20 which receives the adjacent end 19 of the rod and has an outer wall extending round that end, the wall being adapted to prevent opening of the slit when the rod is subjected to compressive loading. The washer 13 may be formed of rubber or a resilient synthetic plastic material moulding, e.g. polyvinyl chloride or polythene; it has a peripheral portion 16 for sealing engagement with the interior of the barrel 10 and a web 18 to provide an abutment for engaging the adjacent end 19 of the rod 11, the latter being gripped by the outer wall of the recess 20 thereby effecting the securing of the washer to the rod. Alternatively, Fig. 5 (not shown), the recess 20 may be provided with a spring metal liner which is formed with a slit and has an internally extending flange for engaging the adjacent end 19 of the rod. In another embodiment Fig. 4 (not shown), the washer is formed with a spigot which extends within the bore of the adjacent end of the rod, and with an annular recess for receiving that end. The spigot is formed with a peripheral rib which engages in a corresponding recess in the bore of the rod.
