Abstract
A machine for inserting a strip into a concrete expansion joint has features to raise and lower insertion disks. The machine has a frame mounted on wheels. The insertion disks are mounted to the same axle as the wheels. The axles are eccentric, having a central offset portion. A control disk mounted to the outside of the axle, rotates the axle to raise and lower the insertion disk. A pair of linkage bars connect the control disk to an upper control disk which is operated by an operator. Another pair of linkage bars connect the rear axle to the front axle for movement in unison.
