Abstract

203,948. Payne, F. J., and Payne, P. C. Nov. 1, 1922. Compound piston pumps; actuating pumps by hand.-In a double-acting multi-stage compressor, for inflating pneumatic tyres &c., having a casing made in halves joined together in a plane midway between the two coaxial cylinders of each stage, each half containing one of the cylinders of each stage and the pistons of each stage being connected together and actuated by a rocking lever, valve-controlled air passages are provided at the ends of the casing and are connected outside the casing so that the joint between the two half casings need not be air-tight. The pistons of one stage are connected by a stem having an elongated slot, and those of another stage by a stem having a notch, the opposite ends of the rocker engaging the slot and the notch. The Figure shows a compressor having parallel cylinders 3, 4 bored out of the halves of a casing 22 split transversely and bolted together by studs or bolts passing through lugs 26. The low pressure cylinder 3 has inlet ports 5 in the side, and outlet passages 6 in the ends controlled bv automatic valves 7 in valve chambers which communicate through ports 8 leading to the high-pressure cylinder. The valve chambers also contain the high-pressure outlet valves 11 supported in casings 29 screwed into them surrounded by sleeves 32 connected by a pipe 10; one of these sleeves is closed by a cap 34, while the other is open to a discharge nozzle 12. The low-pressure pistons are connected by a stem with a slot 17, and the high-pressure pistons by a stem with a notch 20, the slot and notch being engaged by rollers 1, 2 on the ends of a lever 18 rocked by a hand lever.
