MULTIPLE-BAR DWELL MECHANISM

Click to enlargeClick to enlarge Description

The lengths of the links comply with the conditions: B͞C=4.22A͞B, D͞C=G͞F=E͞M=3A͞B, E͞F=2.33A͞B, A͞D=3A͞B, G͞D=5.44A͞B, B͞M=M͞C and A͞G=2.4A͞B. Link 4 is connected by turning pairs E and F to connecting rod 2 of four-bar linkage ABCD and to link 5 which oscillates about fixed axis G. When point B of crank 1 travels along the part of the circle indicated by a heavy continuous line, point E of connecting rod 2 describes a path of which portion a-a approximates a circular arc with its centre at point F. During this period link 5 almost ceases to oscillate, i.e. it practically has a dwell.
