Bent lever 4 turns about fixed axis C. Cylinder 1 is connected by turning pair B to lever 4. Rod 6 of the piston sliding in cylinder 1 is connected by turning pair A to links 2 and 3. Links 3 and 2 are connected by turning pairs D and F to lever 4 and link 5. Link 5 is connected by turning pair E to lever 4 and has pin a at point K which slides along fixed circular slot b. When piston 6 moves out of cylinder 1, the distance between axes A and B is increased, and links 2, 3, 4 and 5 take the positions shown by the dash lines. In the working position of the brace, points C, D, E, F and K are on a straight line.
