Link 2 turns about fixed axis A and has fork f which engages pin b of link 1. Link 5 is connected by turning pairs E and F to link 2 and to link 3 which turns about fixed axis B. Pulling force P, applied to the shackle of link 1, is transmitted by two flat springs a and d which are straightened out and thereby cause horizontal displacement of pin b, turning levers 2 and 3. Pencil e, mounted on lever 3, draws a diagram of the pulling force on moving paper band 4.
