[/D^l DECEMBER IO, 1910. THE SANDERS "TEACHER." THOSE wishing to take up aviation either as a recreation or a pro fession find many drawbacks at the commencement of their under taking, but one of the most formidable, especially to those not simultaneously learning the control of the machine he wishes to pilot, and the principle is applicable to any make or type of aero plane. In the second place the balance of the teacher is so arranged The Sanders Teacher in use. blessed with a long purse, is the risk of smashing the machine while endeavouring to learn how to control and fly it. Even the most apt pupil is certain to find himself in difficulties at some time or another during his probation, and owing to lack of skill the machine is necessarily sacrificed to save his life, or at least to prevent a serious accident. The invention, therefore, of a device which will enable the novice to obtain a clear conception of the workings of the control of an aeroplane, and of the conditions existent in the air, without any risk personally or otherwise, is to be THE SANDERS TEACHER.—The Pivoted Rocker. welcomed without a doubt. Several have already been constructed to this end, and the Sanders Teacher is the latest to enter the field. The aim and object of an invention of this kind is naturally to render tuition safe to the pupil while at the same time giving him confidence. Now there is a tendency to design such an apparatus merely for purposes of balance and without any real resemblance to an actual aeroplane, while the very balance is so exaggerated that the pupil is placed under conditions that are in no way so arduous ia free flight. The Sanders Teacher seeks to overcome both these difficulties. In the first place the teacher so closely adheres to the construction of the actual aeroplane that the pupil in learning to control it is on scientific principles that the conditions are practically the same as if the pupil were actually in the air. The varying force of the wind has effect in almost an identical manner as on a working aeroplane, while the niceties of lateral and longitudinal stability are not carried to an extreme. The device, as will be realised from the description following, is neither costly nor elaborate, while the perfection of workmanship to be found in the Sanders biplane is also plainly noticeable here. One would say that the motto of the firm is "If a thing is worth doing at all it is worth doing well," as even the minutest detail is carried out with most scrupulous care and accuracy and only incor porated in the construction after much thought and experiment. The machine consists of a fuselage-elevator, two lateral ailerons and a rudder either single or double planed. The control is a simple motor steering wheel in front of the pupil connected up with elevator, rudder and ailerons. All these details are standard parts of the Sanders biplane and can be substituted if desired by the same parts of any other type of aeroplane. Thus, the purchaser of a Teacher is buying parts which can be used later if he wishes in the construction of a machine and his outlay can therefore scarcely be considered an extravagant one. The fuselage is slung on to a wooden pivot consisting of a hexagonal bottom on which a cross- way square running on wheels is placed. Above this is a rocker bearing a flat board surmounted by two triangular brackets with a bar running through sockets at the top. This bar also passes through two corresponding sockets on the upper part of the fuselage which is thus slung on the pivot. A bolt runs vertically through the centre of the pivot, beneath the rocker, on which the entire machine can swing round to the wind, the movement being very free owing to the ball bearings on the crossway piece below. The ailerons attached at either end of two 12 ft. spars are braced up by means of wire stays to the fuselage and a mast is situated at the rear of the machine. They are also supported above by a rubber spring attached to two small masts. For the rest, a personal inspection is recommended to aviation instructors as a device worthy of their attention. DOROTHY M. HAWARD. Artillery for Fighting Airships. Two new weapons for offensive use against airships and aeroplanes have jus» been completed at the Krupp Works, Essen, and are now undergoing their tests. One of the guns is mounted on a completely armoured motor car, while the other, of a lighter type, is so arranged on the platform of a trailer, that it can be either used in that position or direct on the ground, it being provided with a carriage of the field artillery type1, and the lurry fitted with runners for lowering the guns to the ground.
