Lecture 15.4 4th Inversion of Slider - Crank Mechanism : Hand pump mechanism

4th Inversion of Slider - Crank Mechanism : Hand pump mechanism : 

Slider ( Originally  4th link ) is fixed / stationary OR Slider link - 4 is Frame [Revised 1st Link] = water pipe (cylinder)

Second link = Driven Slider (Piston rod attached with piston) = Originally  [link 1 - frame]

Third link = Coupler= Originally [link 2 - Crank]

Fourth link = Slider = Originally [ link 3 - Coupler] 

Note: Third link [ Revised] , namely, Coupler is given the input motion (rotary movement) such that Fourth link [ Revised], namely, rocker oscillates / rocks that results in reciprocating movement of piston rod and piston [Revised 2nd Link] within the Revised (fixed) 1st link,  namely, grounded water pipe.
