Can the pitch stabilizer in the picture really work for a plane or glider?
The image shows an automatic pitch stabilizer (the mechanism in the black rectangle) that is based on the vane 50 whose movements up and down would drive, with the help of a force amplifier system, the horizontal front elevator of a Wright glider or plane in such a way as to maintain the aeroplane in horizontal flight.
More precisely if, for a reason or another, the plane have the tendency to dive there will appear a vertical component of the relative wind that will push the vane 50 upward and, through the mechanism already mentioned, the vane will drive the front rudder in such a way as to make the apparatus climb again. If the plane tend to rise, the vane will go down and command the front rudder to make the plane descend.
The question is, can this mechanism really work, at least theoretically? (A stabilizer based on a pendulum is a fallacy, it will not work. In an accelerated system (the plane) the pendulum does not align to the vertical).

(I am not interested in answers regarding the automatic stabilizer in roll, also described in the patent. It is based on a pendulum and it can not work. My question is only about the pitch stabilizer.)
UPDATE: My question has nothing to do with a pendulum stabilizer. The vane-based stabilizer (the subject of my question) works on a completely different principle. In consequence, the answers given to this question, that refer strictly to a pendulum stabilizer, do not help.
