| 20110114457 | EXTRUDED RAIL WITH CONTAINED MOUNTING CAVITY - An extruded rail for mounting objects along the length of the rail that include an enclosed receiving and containment cavity. The extruded rail includes a receiving and containment cavity that extends from an inner surface of the rail. The receiving and containment cavity includes upper and lower walls and a back wall that define an enclosed containment area. An alignment notch is formed in the generally planar outer surface of the side rail and aligned with the receiving and containment cavity. When an object is to be attached to the rail, an opening is formed in the side rail at the alignment notch. As material is removed from the side rail during formation of the opening, the received material is entrapped within the receiving and containment cavity. Thus, the extruded rail of the disclosure receives and contains material removed during attachment of an object to the rail. | 05-19-2011 |
| 20100230249 | CONVEYOR BELT DRIVE SPROCKET RETENTION SYSTEM - A drive sprocket retention system is provided for use in a belt conveyor in which a plurality of drive sprockets are mounted on a rotatable element having an axial keyway formation. The retention system is defined by a key arrangement disposed in the keyway formation of the rotatable element, wherein a recessed portion of a key is received and retained between each drive sprocket and the rotatable element without the need for threaded fasteners. The retention system is movable between a locked position and a release position, wherein the spacing between the drive sprockets is substantially fixed when the retention system is in the locked position, and the drive sprockets are independently movable along the longitudinal length of the rotatable element when the retention system is in the release position. | 09-16-2010 |
| 20090020397 | CONTAINED DRIVE SYSTEM FOR CHAIN CONVEYOR BELT TO REDUCE CATENARY SAG - A conveyor frame assembly for use with a conveyor belt formed from individual links each joined together at pivot points. The conveyor frame assembly includes a drive assembly that pulls the conveyor belt around a drive roller to transition between the upper and lower runs of the conveyor belt. The drive end includes a support block that encloses the side edges of the conveyor belt as the conveyor belt transitions over the drive sprockets. The side frame members each include a continuous retaining channel having a height greater than the thickness of the conveyor belt. The retaining channels formed on opposite sides of the conveyor frame assembly allow the lower run of the conveyor belt to “tent” by creating an angle between adjacent links of the conveyor belt assembly. The tenting of the lower run of the conveyor belt eliminates catenary sag. | 01-22-2009 |
| 20080210529 | CONVEYOR FRAME ASSEMBLY HAVING SIDE RAILS INCLUDING MULTIPLE ATTACHMENT SLOTS AND ADJUSTABLE CROSS SUPPORTS - The present disclosure relates to a conveyor frame assembly that includes a pair of spaced side rails joined by one or more cross supports. Each of the side rails includes a dedicated wire channel and self-contained air flow cavity that enhances the functionality of the conveyor frame assembly. The air flow cavity and the wire channel are formed as part of the side rails separate from typical attachment slots that receive T-shaped connectors. The cross supports utilized with the conveyor frame assembly are attached to the side rails by upper and lower connectors that are each accessible from the top of the conveyor frame assembly. Specifically, the cross support includes a center web and laterally offset attachment webs that allow for easy and convenient construction and field modification of the conveyor frame assembly. | 09-04-2008 |
