ABSTRACT:
A bell-crank lever having substantially stiff lever arms, which are approximately at right angles to each other, is connected to a stationary part by a film hinge that is secured adjacent to the junction of the lever arms and defines a bending axis which is at right angles to the plane of the bell-crank lever. An oscillating arm is secured to the free end of one of said lever arms and extends approximately parallel to the other of said lever arms and about film hinges which define bending axes that are at right angles to each other is bendable in the plane of the bell-crank lever and at right angles to that plane. An oscillating beam bar is connected to the other of said lever arms by a film hinge defining a bending axis at right angles to the plane of the bell-crank lever. The oscillating arm has in its free end portion a bearing bore for connection to a driving crank pin. The oscillating beam bar is substantially aligned with the axis of rotation of said crank pin.
