1483597 Steam engines; IC reciprocating engines H E MUNGEAM 2 Jan 1975 [4 Oct 1973] 46475/73 Headings F1B and F1M A reciprocating steam engine, Fig. 1, or I.C. engine, Fig. 2, (see below), comprises a housing 1 in which are provided two pistons 2, 3 respectively fast with sleeves 2a, 3a each defining a cyclinder for the other piston, the pistons and cylinders reciprocating in opposite directions and being restrained also to oscillate angularly about the axis of the housing 1 by an inclined transverse rod 6 connected at its ends 6a, 6c to crank arms 6b, 6d on the driveshaft and passing through bearing blocks 3b, 2e in the sleeves 3a, 2a respectively. The reciprocation and oscillation of the sleeves acts to cover and uncover steam inlet and outlet valves 9, 9a on opposite sides of the housing 1. A fixed piston 13 in the oil sump 15 co-operates with the inside of piston 2 to force feed oil through lines 11 and to suck it back through lines 10. Again, Fig. 2, an I.C. engine comprises a housing 21 having two pistons 23, 31 respectively fast with sleeves 22, 31, reciprocation and oscillation of the pistons and cylinders controlling the inlet and exhaust ports. The sleeve 22 is in the form of a hollow piston co-operating with the casing to define an air chamber 21a feeding air to the first cylinder defined by sleeve 22. A similary air chamber 30 is defined by a fixed piston 24a co-operating with a hollow piston 23.
