SALVATORE DE SANTIS, OF NAPLES, ITALY.
MEANS FOR STABILIZING- AER-OPLANES.
Specification of Letters Eatent. Patented A 8 192% Application filed April 30, 1920. Serial No. 377,926.
To all whom it may concern:
Be it known that I, SALVATORE DE SAN'IIS, a subject of the King of Italy, and resident of Naples, Italy, have invented certain new and useful Improvements in Means for Stabilizing Aeroplanes (for which I have filed application in Italy April 18, 1-919) of which the following is a specification.
The invention relates to flying machines and particularly to the stabilizin wings thereof and has for its object to so stabilize the wings that they will have a constant supporting or lifting power.
The invention consists of a lever mechanism adjustably connected wit-h a pivoted stabilizing wing and to which a spring is secured.
In the accompanying drawing Figure 1 is an elevation partly in section of a portion of an aeroplane having the improvement applied, and
Figure 2 is a similar view of a hydroplane showing a modified form of the improvement.
Referring to Figure 1 A is the frame of a portion of an aeroplane, and E is the stabilizing wing pivoted at 0 to the frame. To the frame A the lever Z is pivoted at 0 directly below the pivot of the wing and the other end of the lever is connected to the wing by the adjustable rod 6. The pivoted end of the lever Z carries an arm Z) which stands at an angle thereto and to which arm one end of the spring on is secured, the other end of the spring being secured to the frame at m. A stop at is arranged on the frame and with which the arm 5 is adapted to engage to limit the swinging movementof the lever Z.
To the frame is pivoted a bell crank lever a, one member of which engages the connecting member of the spring m and to its other member the operating rod 2 is secured. By this means the tension of the spring can be increased by the pilot to vary the supporting power of the wing.
In Figure 2 the stabilizing wing E is pivoted at o to the frame A of the hydroplane the same as in Figure 1. Instead of a single lever two parallel levers Z Z are pivotally connected at their ends by arms 6 b are employed. The lever Z is connected to the wing E by the adjustable rod t and one end of the spring m is connected to the arm 6 For adjusting the tension of the spring and thereby the supporting power of the stabilizing wingythe arm 6 is provided with an extension 6* to which one end of an adjustable rod 5 is secured, the other end of the rod being secured to an operating member B.
By adjusting the rods 2? and t the sensibility of the movement of the parts can be increased or decreased.
By this invention the wings will be stabilized in the various positions they may assume and thereby their supporting power will always remain the same.
'What I claim is- In a flying machine, a pivoted stabilizing wing, a spring, a lever mechanism with which the spring is connected, and means for adjustably connecting the lever mechanism with the wing.
In testimony whereof I have hereunto signed my name in testimony whereof.
SALVATORE DE SANTIS.
