r OCTOBER 3, t9i8. v connecting them with the fuselage'are in the form of steeltubes. Of these there^are a considerable number, some plain,straight tubes and others bent to the shape of a letter U.The arrangement of these bearers and their supports is shownfrom two points of view in Fig 3. The inset shows one ofthe split collars or slips by means of which the engine is secured to the two bearers. Fig. 4 shows some constructional details of the body and tail planes of the Fokker biplane. The fixed tail plane as well as the divided elevator are built up of steel tubes, the general arrangement being shown in Fig. 1. In the general sketch of Fig. 4 the ribs of the tail plane have been omitted so as to show.more clearly other details. Like the tail plane and elevator, the rudder and its fin are built of steel tubing. The fin has the peculiarity that its front end is slightly offset to port, probably to counteract a tendency, caused by the torque, to turn to the left. This offsetting of the fin would • probably result in a tendency to turn to the right with the engine switched off, but with regard to this we have no data, as the machine has not been flown by any of our pilots, being in a too damaged condition to make this expedient. The attachment of the front end of the fin to the front trans- verse tube of the tail plane is shown at A, Fig. 4. The detail at B shows a hinge that is very extensively used on the Fokker biplane, both for the elevator and rudder, and also for the ailerons. The construction of the hinge will be easily under- stood from a reference to the sketches. A sheet aluminium plate has a portion stamped out as shown to form the front half of the bearing, the remaining two strips forming the rear half. Into the space thus formed is forced a bush that pro- vides the bearing surface for the rudder or elevator tube. The whole hinge impresses one as being very neat and simple, and the only objection that might^be raised against its em- ployment is that each hinge has to be pushed into place before the elevator or rudder ribs are welded to the tubular leading edge. As, however, everything is, apparently, done over jigs this is a matter that is easily managed while building up the control organs. The sketch at D shows the split collars used for securing the two diagonal tubes which reinforce the body frame at the point where occurs the handle by means of which the rear portion of the body is lifted when handling the machine on the ground. The body of the Fokker biplane terminates at the rear in a sort of false stern post of wood, the last vertical tube of the body being placed some little distance farther forward. This tube, which is welded at its ends into the angle formed by the converging longerons at this point, has mounted on its upper end the attachment for the tail plane. This is in the form of a simple bolt, which does not appear to provide any adjustment for the angle of incidence of the tail plane, although'it might easily be extended to do so. The front attachment of the tail plane to the top longerons is by means of two bolts passing through short lengths of tube welded to the inside of the longerons. At its lower end the vertical tube referred to above carries the attachment for the tail skid, the details of which are shown at F. The upper end of the tail skid is sprung by coil springs and the amount of travel is limited by a cable as shown at E. The sketch at G shows the tubular quadrant to which the bracing wires of the body are attached. As in the triplane these wires are simply doubled over the quadrant, and are thus not strictly speaking in duplicate. Only a single wire strainer is incorporated with each double wire, the method of locking the strainer being as shown in the sketch.
