Abstract
The sealing assembly (10) of the present invention comprises a resilient sponge rubber tube (12) supported and retained by a metal bar (14) running through the tube and extending through slots (16) in the outlet side frame (18) terminating at each end in a retaining assembly (20). The seal member-slot relationship is such that when the gate (30) is open (FIG. 1), the seal member (12) rests on the gate with its retaining bar (14) in the lower portion of the side frame slots (16). Should there be an obstruction on the gate (not shown) such as adhering lading, the seal (12) when forced toward the outlet pan (40) will cause the retaining bar to rise in the slot to position (16b). This movement will allow the seal to ride over the obstruction and prevent the seal (12) from being pinched in the clearance slot (34) above the gate. As the gate is fully closed the upturned flange (32) at the back edge of the gate compresses the seal (12) against the outlet pan (40). As the seal (12) is compressed, the support bar (14) travels in the slot (16) at each end to the position (16b) allowing the seal to be compressed uniformly.
