CORRESPONDENCE. Automatically Stable Aeroplane. [I^37] The following is a description of an automatically stable aeroplane invented by myself and provisionally protected by Patent No. 25,364. It will be seen from the accompanying drawings that the machine is fitted with twelve planes, two sets of four main planes and one set of four tail planes. Unlike most aeroplanes the wings of this machine are not rigidly fixed direct to the fuselage but are placed at the end of struts, which UNAFFILIATED CLUBS. Edinburgh Ae.S.

I and 2), and at the top of each strut a chain cog-wheel is fixed working in a socket as big as itself. The middle portion of the front spar of the plane forms a diagonal of the wheel to which it is rigidly fixed (Fig. 7). At the base of each strut are two small cog-wheels of American fibre (for lightness) which are fixed as depicted in Fig. 6, the lower one passing through a hole in the cylinder and working round the cog-band on the fuselage. Working on the same axle as the top cog-wheel is a small flanged chain cog-wheel, which is connected to the wheel at the top of the strut by a light chain (Figs. 6, 7). I 1 ,lKu' I FIG 3 10TAL ARCA OrrlAINPLANCS 512 $Q.FT TOTAL AREA or TAIL PLANES GOiqrT ARCA0TELEVAT0R5 IE iQ.TT RUDDER 9SQFT are rigidly fixed to cylinders (skeleton cylinders covered with canvas), which are capable of revolving round the fuselage, thus also enabling the planes to move in a circular direction round the longitudinal axis of the machine. Between the planes and the fuselage is a system of small cog wheels and chains which is brought into action by any difference of lateral pressure on the planes on either side and acts so as to equalize that pressure. Description of Automatic Geat.—Round the fuselage at three certain places there is fixed a band of small cogs (Fig. 5)1 and over this the cylinder is fitted so that it can revolve round the fuselage. The wheel at the top of the strut has the same number of cogs on it as the cog-band round the fuselage, thus necessitating the fuselage being as narrow as possible. This arrangement of wheels is such that as the cylinder and struts move round the fuselage in one direction the wheel at the top of each strut turns to exactly the same degree in the opposite direction, thus always keeping the planes in a horizontal position (see Figs. I and 2) and ensuring a constant lifting area and an equal distribution of plane surface on either side of the fuselage. Now suppose a gust of wind strikes the under surface of Plane A, Fig. i, this plane gives to the wind and moves upward and round, 179
