MULTIPLE-BAR MECHANISM FOR TRANSMITTING OSCILLATION TO A PARALLEL SHAFT

The lengths of the links comply with the conditions: A͞D=A͞C, D͞H=E͞C, H͞K=E͞F, D͞K=C͞F,
L͞K=G͞F and L͞B=B͞G. Upon rotation of crank 1 about fixed axis A, link 2 oscillates about fixed axis B. The symmetrical dimensions of the links provide for more favourable loading of driven link 2.
