Link 2, sliding in fixed guides b-b, is connected by sliding pair B to link 1 which, in turn, is connected by turning pair A to circular slider 3. Slider 3 moves along circular slot a-a of radius D͞A and with its centre at point D. When slider 3 moves along slot a-a, link 2 reciprocates in guides b-b. Link 1 participates in two translatory motions simultaneously: along axes x-x and y-y.
