  • Patent number: 10124962
    Abstract: A roll-formed steel slat for use in a reciprocating floor slat conveyor system. The roll-formed steel slat is formed in a manner so as to have an upper, load-carrying surface, and a pair of downwardly depending side legs. Each side leg terminates in a foot. One foot is vertically offset from the other to provide a “hold-down” function that prevents the slat from vertically rising as the slat reciprocates back-and-forth.

  • Patent number: 8424674
    Abstract: Movable conveyor slats (12) have side parts (74, 76) which rest on top parts of bearings (92). The bearings (92) have a generally U-shaped cross section and they fit on wings (52, 54, 54?) which extend outwardly and slope upwardly from the sides of a fixed conveyor slat (10, 10?). Fixed conveyor slats (10, 10?) have base portions (18, 18?) and upper insert portions (20, 20?). The inserts (20, 20?) have downwardly extending ribs (62, 64) on their sides which extend into upwardly opening grooves (48, 50) in the base portions (18). The movable slats (12) have web (80, 82) and lower flange portions (84, 86) which with the side parts (74, 76) of the slats (12) form laterally outwardly opening channels. The wings (52, 54, 54?) and the bearings (92) are received within the channels (88, 90).

  • Publication number: 20110236168
    Abstract: An improved outer reciprocating floor slat for use in a truck trailer or the like. The outer floor slat is located adjacent to a trailer's side wall. The floor slat has a portion that extends laterally upwardly and outwardly until it reaches the trailer's side wall at an elevation above the normal load-carrying floor elevation of the reciprocating floor slats. The upwardly extending portion facilitates material movement away from the corner region where the reciprocating floor normally intersects the trailer's side walls.

  • Publication number: 20100025193
    Abstract: Conveyor slats (14, 14?, 14?) are supported for longitudinal movement along support beams (12, 12?). The slats (14, 14?, 14?) are constructed from a structural plastic material and the support beams (12, 12?) are constructed from metal. The support beams (12, 12?) have a center portion in the form of an upwardly opening channel formed by side walls (22, 22? and 24, 24?) and a bottom wall (20, 20?). A top is formed by side parts (16, 16? and 18, 18?). Side parts (16, 16?) project laterally outwardly from the upper edges of the side walls (22, 22?). A top side part (18, 18?) projects laterally outwardly from the upper edges of the side walls (24, 24?). The conveyor slats (14, 14?, 14?) have a top wall (40, 40?, 40?), a pair of side walls (50, 50?, 50? and 52, 52?, 52?). Inwardly projecting flanges (54, 54?, 54? and 56, 56?, 56?) project laterally inwardly from the side walls (50, 50?, 50? and 52, 52?, 52?).

  • Publication number: 20090000918
    Abstract: A reciprocating slat conveyor includes a plurality of side-by-side support beams (12) and conveyor slats (14) which fit onto the support beam (12). The support beams (12) are constructed from metal. The conveyor slats (14) are constructed from plastic. In one embodiment (FIGS. 1-4) the plastic slats (12) are snapped fit onto the support beams (12). In some other embodiments (FIGS. 6 and 7) the conveyor slats (110, 112) are slid lengthwise onto the support beams (102).

  • Publication number: 20080304947
    Abstract: A sheet member (30) is positioned on the slats (18) of a reciprocating slat conveyor in a container (10). A strap (32) leads from the forward end of the sheet member (30) to and through a guide eye (38) that is mounted at an elevated position (26) adjacent the front wall (16) of the container (10). The strap extends downwardly from the guide eye (38) to a winding reel (36) driven by a motor (34). A block (40) is connected to the strap (32) in a position so that when the front end of the sheet member (30) has been moved by the strap (32) into an elevated position adjacent the front wall (16), the block (40) on the strap (32) will move through the throat (124, 108) of the guide eye (38) to the opposite side of a latch spring (42) that defines one side of the throat (124, 108). When in this position, the block (40) contacts the latch spring (42) and is hard against a reverse movement of the strap (32) and block (40) through the guide eye (38).

  • Patent number: 7316307
    Abstract: An elongated plastic slide bearing (10) comprises a top (30), sidewalls (32, 34) depending from the top (30), and connecting to walls (36, 44, 48 and 38, 46, 50) that form laterally inwardly extending recesses (40, 42). Lock ribs (62, 64) extend upwardly and inwardly from the inner walls (44, 46) of the recesses (40, 42) to upper edges (66, 68). The upper edges (66, 68) are spaced below the bearing top (30). The bearing (10) is adapted to be set down onto a support beam (14) that includes laterally outwardly projecting lock flanges (22, 24) at its top. The lock ribs (62, 64) contact the lock flanges (22, 24). When the bearing (10) is pushed downwardly, the lock ribs (62, 64) bend outwardly and allow the lock ribs (62, 64) to move into a position below the lock flanges (22, 24). When that happens, the lock ribs (62, 64) assume substantially unstressed positions in which their upper edges (66, 68) are below the lock flanges (22, 24).

  • Patent number: 6129299
    Abstract: A reciprocating slat conveyor (22) conveys a body of bulk material (16) to the outlet end (21) of a container (12). The body of bulk material (16) is moved against a sloughing wall (10). The sloughing wall (10) includes a plurality of slats (40) that are mounted for generally up and down reciprocation. The slats (40) carry bulk material engaging teeth (60, 62). In response to the generally up and down movement of the slats (40) the teeth (60, 62) break loose the bulk material (16). The loosened bulk material falls down onto a secondary conveyor (14) which leads it away from the container (12).
