  • Fold-over chute safety device
    Patent number: 6719118
    Abstract: The spacing device mounted to a two-section chute system prevents inadvertent contact between the two chute sections. The spacing device includes a mounting flange and a blocking member positionable between first and second pivotally attached chute sections of a concrete mixing truck. The first chute section comprises an annular flange that is configured to contact an arcuate edge of the second chute section. The mounting flange is connected to a second end of the first chute section and the blocking member is attached to the mounting flange. The blocking member comprises a contact surface that is configured to engage a portion of the arcuate edge of the second chute section when the spacing device is in a blocking position. In the blocking position, the spacing device holds the first and second chute sections in a partially open position to prevent unintended contact between the chute sections.
