Abstract: 9374. Rees, I. April 21. Gas or explosivevapour engines.-A radial multiplecylinder one-crank two - stroke - cycle engine is described. The driving - gear, consisting of a crank-pin and slot mechanism, is contained within the central casing, on each side of which a unit, consisting of a working cylinder, an air-compressing cylinder, and a mixture-compressing cylinder, is mounted. The crank-shaft is preferably vertical. General arrangement; cycles; driving-gear. - In Fig. 1, a working cylinder A, mixture - compressing cylinder J, and aircompressing cylinder I, are shown mounted on each side of a squate casing D. E a c h air - compressing cylinder is connected by a pipe K with the opposite working cylinder, and each mixturecompressing cylinder by pipes x, x<1> with the working cylinders on the adjacent side of the casing: The aircompressing cylinders I draw in air and a little water which are compressed and delivered to the opposite working cylinders A just when the exhaust ports L are uncovered, so as to flush the cylinder. The mixture cylinders J, of relatively small bore, take in petrol, paraffin, petroleum, or aclohol, with a small quantity of air. The mixture is compressed and delivered past the valve J<1> to the explosion cylinder, which is so situated as to produce the proper direction of rotation. The piston-rods of the respective cylinders are connected to the cross-beads E which form slots in which work blocks F fitting over the crank-pin B carried by the crank-disk G. Instead of this driving-gear, connecting-rods working inside loops which connect opposite piston-rods may be employed. Valves and valve-gear; vaporizers; governing.- The cocks J<1> on the mixture cylinders J are actuated by tappet rods R and links R'. R<2>, are kept closed by springs R<3>, and are timed to open just as the ports L are closed by the pistons on their compression strokes. The rods R are struck by the cross-heads E. The mixture is forced past valves T into the cylinders against compression pressure. Fuel is drawn through the valve J<3>, Fig. 2, along with air and both enter the mixture cylinder through the valve J<2>. The mixture cylinders may be heated by exhaust gases in the jacket U<3> to assist in the vaporization of the fuel. According to the Provisional Specification, an air-chamber surrounds the mixture cylinder, in order to cool the latter and to supply hot air with the oil fuel. The explosive-mixture supply is regulated by a rack-and-pinion device which controls the valve J3. The racks and pinions are moved simultaneously by a ring Y mounted on the casing D, through radial arms and rods Y'. The ring may be actuated by a governor. Cylinders ; exhaust chambers.-The exhaust ports L are in the cylinder walls. The ports on one side of the cylinder are connected direct, and those on the other side by means of a pipe U<2>, to the jacket U<3> of the mixture cylinder. Charge, arrangement of, in cylinder; igniting; reversing.-The air. and water vapour supplied by the pump I is compressed by the main piston and the mixture, which is forced in at the small end of the cylinder, is mostly retained at the end where the sparking-plug P' is placed. Thus a relatively. rich mixture surrounds the plug, and firing of the charge is facilitated and is not interfered with by the presence of water vapour. The engine is reversed by slowing down and advancing the ignition, and at the same time altering the direction of flow of the mixture to the cylinder by means of a twoway cock.
