Eccentric 1 rotates about fixed axis A. Link 2 slides in fixed guides p-p. Link 2 has prismatic guides 3 with slot a. Guides 3 are rigidly secured to gears 5 which mesh with pinions 4. Pinions 4 are turned by handwheel 6. The displacement of link 2 is s₂=A͞B(sin(ϕ)—cos(ϕ)tan(α)) where A͞B = distance from axis of rotation A to centre B of eccentric 1, ϕ = angle between line AB and axis r-r, α = angle between axis q-q of slot a and axis r-r. When eccentric 1 rotates, slotted link 2 reciprocates. The stroke s₂ of slotted link 2 is adjusted by changing angle of inclination α of prismatic guides 3, attached to gears 5, by means of pinions 4.
