The mechanism gives long stroke length of orange slider L = 4R.
R is crank radius (in yellow) and length of conrod (in green).
If the crank is driving the mechanism faces unstable positions when the crank rotary axis and the slider pivot are in line.
To fix this problem here the mechanism is added with two gears of equal tooth number to make the conrod driving.
Pink gear is the input, green gear is fixed to the conrod.
A working cycle corresponds 3 revolutions of the pink gear.
It is possible to use chain d
