Pump-actuating mechanism; oscillating-cylinder pumps. -Relates to inflating-apparatus for the tyres of motor-cars and other vehicles of the kind in which a pump cylinder a is pivotally suspended from some portion of the vehicle frame, while the piston-rod is attached to a crank-pin on the vehicle wheel, and consists in a form of clamping-device for securing the crank-pin to the wheel, and a form of pivot for carrying the pump cylinder. The handle b of the inflator is provided with a sleeve c adapted to embrace the crank-pin when secured to the wheel. The crank-pin is screwed into the back plate e of a pair of clamping-plates e,/, the front one of which fits loosely on the pin and is tightened against the wheel spokes by means of a hand-nut h. The adjacent faces of the clamping plates may be bevelled to facilitate their attachment to wirespoked wheels. The pump cylinder or its footplate k is held by set screws m in a clip j integral with or secured to a spindle n mounted in bearings o on the underside of the foot-board.
