  • Patent number: 4872233
    Abstract: The present invention entails a street sweeper having a drag shoe assembly secured to each side of the street sweeper for confining dirt, debris, etc. Each drag shoe assembly includes an upper frame structure and a drag shoe coupled to the upper frame structure via two generally parallel interconnecting coil spring links. In the event the drag shoe encounters a lateral obstruction while the street sweeper is turning or moving laterally in any way, the coil spring interconnecting links will flex and enable the drag shoe to move laterally back and forth to avoid damage to the drag shoe or frame structure of the street sweeper.
