One end of the assembly is connected to a spindle for reciprocating the same. The other end of the assembly is connected to a counterweight whereby the spindle and the counterweight are simultaneously reciprocated in opposite directions. The counterweight is generally U-shaped such that its center of gravity is located near the spindle. | |
