[j%Mf MARCH 28, 1914- crank-case, and that through these extensions series of ports are cut at such positions that they are uncovered by the pistons towards the end of the induction stroke, whereupon a very rich mixture enter* the cylinder, and mixing with pure air drawn through the exhaust valve, forms an explosive gas. The exhaust valve is opened sufficiently early on the power stroke to allow the greater portion of the gases to escape before the ports are uncovered, thus any possi bility of blowing irttck into the crank-case is avoided, apart from the fact that the gas there is so rich that it is non-explosive. A special means lor controlling the engine is fitted in order to permit a low speed rear end ot the crank-shaft is entirely closed, and air is admitted through the noss piece, thus entirely eliminating fire dangers. Two sizes of this type of motor are now manufactured—a 7- and a Q-cylinder of 80 and 100 h.p. respectively—the bore and stroke being 110 mm. and 150 mm. in both models. Statax Engine Co. THE two engines shown on the stand or this company embody an interesting construction, the cylinders—of which there are three in the 10 h.p. and five in the 40 h.p.—being arranged axially, Sectional elevation through the cylinder and crankcasj of the 40 h.p, Statax rotary engine, showing the details of valve arrangement. of revolutions to be attained. This mechanism is operated by the handwheel seen on the extreme right of the figure, which is so con nected to the valve gear by shafting and levers that when the wheel is rotated, the times of opening and closing the exhaust valves are varied, thus throttling the exhaust gases, Risk of miss-fires has been minimised by the adoption of the pump system of fuel supply ; while since the carburation takes place within the crank-case, there is no possibility of freezing up occurring when a machine is flying at high altitudes or in cold weather. The parallel to the axis of rotation. The steel cylinders, which are threaded into a number of circular aluminium cooling discs con centric with the axis of rotation, are held between casings containing the driving gear and the valve operating gear, as shown in the accompanying sictional drawing, the whole being suitably trounted upon ball bearings supported on a central stationary hollow shaft which is attached to a framing. Upon the shaft a disc is secured, making an angle with the axis of the shaft, and a ring, to which the connecting-rods are attached by universal joints, is mounted thereon. The first Argyll aero engine built by Argyll*, Ltd.. on the elliptical single sleeve-valve system, and which has been on exhibition at Olympla. The above photograph was taken at the conclusion of a series of brake tests before belnj sent off to the Show. The portraits, from left to right, are M. Henri Perrot, chief engineer and designer, Mr. J. S. Matthew, managing director of Argylls, Ltd., and Bailie P. Burt, the inventor of the engine. This engine, which is entered for the War Office Competition, during its preliminary tests has given 130 h.p. at 1,200 revsv 340
