Abstract

4065. Stasiak, J. Feb. 17. Aerial machines without aerostats; steering.- Consists in an automatically-controlled aeroplane which will carry a bomb to a predetermined point, diecharge the bomb, and return to its original position, the travel of the aeroplane, prior to dropping the bomb, being controlled by a device which is set before the aeroplane commences its journey. In the form shown in Fig. 2, the body 1 of the apparatus is provided with a motor 5, a cranked shaft 2, propellers 3 at each end, rudders 72, a supporting-plane 33, and travelling-wheels 6. The plane 33 is pivoted at 29 between uprights 27 carried by the body, the shaft 29 being provided with an arm 39 having two fingers 40 which engage a lever 42 on a shaft 43, a second lever 44 on the shaft being connected by a rod 45 to the reversing- lever 46 of the engine. With the plane set as in Fig. 2, the apparatus travels to the right ; reversal of the plane and the engine, for travel to the left, take place aimultaneously when the bomb is dropped. The bomb 60 is carried by a wire 59 from a notched sector 58 mounted on a shaft 57, the sector being retained in the position shown in Fig. 2 until a trigger 63 is released from the notch 64 ; the sector then rotates to release the bomb, and an arm 55 on the shaft 57 wipes over the arm 39 on the shaft 29 of the plane, thus reversing the plane and engine for the aeroplane to commence its return journey. The travel of the apparatus, prior to the release of the bomb, is controlled by a belt 20 which is wound at one end upon a shaft 14 and at the other end upon a shaft 15, the belt also passing round pulleys 24 and 23. The pulley 23 is carried by a pivoted frame 23<a> which keeps the belt taut ; the pulley 24 is the driving-pulley and is driven by gearing 8, 9. The shafts 14, 15 are geared together by spur-wheels 13, 16. The shaft 15 carriei a bracket 17 to which is pivoted at 18 a lever 19. to which one end of the belt 20 is attached. A spring 21 acts against one end of the lever 19, and the opposite end engages a stirrup 22 carried by the shaft 15. The distance that the aeroplane travels before the bomb is released is controlled by the length of belt initially wound round the shaft 15, and lever 19. As the apparatus travels forward, the belt is unwound from the shaft 15 and wound upon the shaft 14. When the lever 19 is free, the pull of the belt moves the lever outwards in the stirrup 22, thus releasing the trigger 63, Fig. 2. Reversal of the engine unwinds the belt from the pulley 14, and in this travel of the belt, a hook 26 thereon engages a lever 51 which, by means of mechanism 49, 48, 47, stops the engine when the device has returned to the starting-point.
