ABSTRACT:
A reciprocating floor conveyor comprises a plurality of adjacent elongated floor members (10). Each floor member has first and second sides (14, 16), each of which may include a longitudinal dovetail groove (24, 56). A first resiliently bendable elongated elastomeric seal (26) is provided for each floor member (10). The first seal (26) has an inboard base portion (28, 50) captured within the first side's dovetail groove (24) and an outboard portion which includes a branch strip (52) extending from the inboard portion (28, 50). The branch strip has a free edge (44, 54) positioned to contact a confronting surface (16) of an adjacent floor member (10) and has a stiff resiliency urging its free edge (44, 54) toward the confronting surface (16). A second bendable elongated elastomeric seal (58) may be provided. The second seal (58) has a retaining base portion (60) formed at a first edge thereof and extends generally upwardly therefrom to a second outer edge (68). The retaining base (60) is shaped to be engaged within the second side's dovetail groove (56) such that the second seal (58) is bendable from a position where it is extending generally outwardly from the second side (16) to a position substantially parallel to and adjacent the second side (16). The outer edge (68) is positioned to contact a confronting surface (14) of an adjacent floor member (10) above a dovetail groove (24) formed in the adjacent floor member's first side (14).
