ABSTRACT:
An overcenter, spring loaded linkage is disclosed for applying a lifting force to a pick-up broom of a street sweeper when the broom is new and heavy, and for applying a downward pressure on the broom when the broom is worn and light in weight. The linkage maintains a substantially constant pick-up broom pattern on the surface being swept throughout the useful life of the broom in spite of a substantial reduction in broom diameter due to wear.
