  • Patent number: 5967295
    Abstract: A flexible guide rail support post comprises a support bracket for mounting to a frame element, a guide element secured to the support bracket, and an actuating member extending through the guide element and having a handle at one end and a guide rail clamp at the other end. A spring surrounds that portion of the actuating member between the handle and the guide element. The guide rail support is movable inwardly and outwardly via movement of the actuating member with respect to the guide element. The inner diameter of the guide element and the outer diameter of the actuating member are selected so that the actuating member and associated guide rail clamp is permitted to move in a range of directions. A spacer is provided for locking the actuating member in at least two fixed positions with respect to the guide element.

  • Patent number: 5803687
    Abstract: A compression clip of the present invention comprises a bolt and a self-tightening member having two side sections and a grooved intermediate section therebetween. The intermediate section has a hole for receiving the bolt. Preferably, the intermediate section has grooves on both an interior and exterior surface thereof. After tightening of the clip, the intermediate section flattens to become somewhat planar and the side sections are compressed inward to securely engage a guide rail or wear strip within the clip.

  • Patent number: 5692596
    Abstract: A rail guide support assembly for assembly line and conveyor systems utilizes a split support rod which allows convenient visual confirmation of the positioning of the guide rails. The rod comprises two halves formed longitudinally, and a portion of the rod mates to form an indicator of the guide rail position relative to the conveyor belt and path of the product being conveyed. Adjustable positioning in multiple directions is possible, such that one or more guide rails may be differentially spaced both vertically above and laterally along the conveyor belt. The split rod may also incorporate a contoured design which keys the halves together to facilitate their assembly.

  • Patent number: 5310047
    Abstract: A conveyor system guide shoe for guiding a conveyor chain or belt from the catenary sag onto a return way, wherein the guide shoe has multiple and reversible wear surfaces, each of the wear surfaces extending the width of the guide shoe. The guide shoe is reversible so that either one of the multiple wear surfaces can be utilized. The guide shoe also has grooves into which the wear strips of the return way can be inserted end-wise. A square support hole is provided through the center of the guide shoe for supporting the guide shoe while preventing its rotation. Support pins are also provided to secure the wear strips within the grooves of the guide shoe.

  • Patent number: 5190145
    Abstract: A multifunction return-way system for one or more chains in a conveyor system. U-shaped mounting clips, having U-shaped arm ends, are snapped onto cross members between frame portions of the conveyor system, and are shaped to have snapped therein wear strips that are oriented in serpentine manner as viewed from above. Portions of the wear strips are maintained spaced apart by spacers mounted onto the rods and by spacer pins that are provided on the mounting clips for association with each other or with side frames. The mounting clips are thus trapped in desired locations. Intermediate clips, or pinch clips, are provided to hold central regions of the wear strips close to each other, at regions where there are no cross members.
