ABSTRACT:
A floor conveyor junction seal gap closure includes a closure member pivotally mounted on and resiliently connected to a bracket extending upward from a conveyor switch mechanism. The floor conveyor includes a main line and a diverging branch line, both adapted to carry load trolleys connected by posts to load carriers positioned above the floor level. Floor slots are provided to clear the connection posts, and the slots are closed by split resilient seals. The seals are opened by the connection posts moving through them and resiliently close behind the posts. A seal gap is formed at the area of divergence of the branch slot from the main slot. The closure plate is positioned below the seal gap to normally close the seal gap. The resilient mounting of the closure plate allows it to be deflected to allow a connection post to pass through the seal gap and afterward returns the closure plate to its neutral position to close the seal gap.
