292,738. Wright, A. H. May 2, 1927. Two-stroke-cycle engines; driving-gear.-In a rotating cylinder engine the pistons 11 reciprocate in a cylinder 10 which reciprocates in cylinders 9, the three bodies rotating in a fixed casing 15, 16. The pistons are rigidly connected by a bar 12 on which is formed a bearing for a journal 36 carried bv a rod 35; the reciprocating cylinder has a bearing 10<a> for a similar journal on the rod. The rod forms part of a swash-plate gear; its ends are received by a ring 32 carrying the inner member 32a of a ball-race, the outer member 34 being carried by the centre part 16 of the fixed casing. The bearings reciprocate in slots in the cylinders 9 and 10 and constrain the three bodies to rotate with the swash-plate, the piston and cylinder 10 reciprocating in opposite directions; the cylinders 9 &c. revolve in shafts 14 attached to the cylinder heads. Mixture is drawn from a carburettor 23 into an annular chamber 16<a>; it passes thence through passages 22 formed on the cylinders 9 to inlet ports controlled by automatic valves 20. The interiors of the cylinders 9 with the cylinders 10 form precompression pumps, the mixture being delivered to the combustion chamber in the cylinders 10 through valves 28. Terminal exhaust ports 26 in the cylinders 10 register with ports 24, Fig. 5, in the cylinders 9 at the end of the power stroke, the exhaust passing to a spiral outlet passage 25 formed in the fixed casing. The sparking-plugs are mounted in the pistons. Cylinders, cooling.-Spiral ribs 30 on the cylinders circulate air through the casing, the air entering through the channel 25 after the exhaust has ceased. Pumps.-Vanes 19 formed on the cylinders 9 near the entrance to the passages 22 assist in forcing the mixture into the. cylinders, and blades 31, Fig. 5, help to withdraw the exhaust from the cylinders.
