It was proposed in 1877 by A. B. Kempe.
Length of blue bars: a
Length of yellow bars: a + a
Length of green bars: 4a
Distance between revolution joints of pink bars: 4a
Numbering:
0 for the fixed pink bar,
1 for the next pink bar, …
n for the last pink bar,
i = 1 to n
A1 is angle between bar 1 and bar 0
Ai is angle between bar i and bar 0
The mechanism maintains relation: Ai = i.A1
i.e.: A2 = 2.A1 ; An = n.A1
Theoretically it can be used for dividing an angle into n equal portions or for velocity multiplication of n times.
