Abstract: A cleaning apparatus for an overhead conveyor system is disclosed which provides continuous cleaning of the system for smooth, trouble-free operation. The apparatus preferably includes one or more exteriorly-mounted wire brush assemblies which are arranged on the guide-rail of the conveyor system for operative cleaning engagement with the movable conveyor. A threaded adjustment arrangement is preferably provided so that the pressure exerted on the conveyor by the cleaning brushes can be selectively varied. For conveyors comprising an enclosed, box-section guide rail, the present apparatus is preferably configured to include a tension-carrying internal brush assembly which is integrated into the conveyor itself. In the preferred form, cleaning engagement is effected between the exteriorly-mounted brushes and the tension-carrying internal brush whereby the internal brush is periodically cleaned.

Abstract: The outboard motor locking device includes a block which is fixed to the inner wall of the transom of a rowboat and which has a pair of downwardly extending clamp screw receiving slots that are adapted to receive the clamping screws of an outboard motor mounting clamp. Within the block between the slots is a cavity and an arm is rotatably mounted therein about the midpoint thereof. A pin is pivotally connected to each end of the arm and each pin is received in a pin hole which traverses and extends across one of the slots. A key operated lock is connected to the arm for rotating the arm to move th pins into and out of latching positions across the slots for locking the clamp screws within the slots. The locking device further includes a cover which is pivotally mounted to one side of the block and is receivable over the outer ends of the clamp screws and a portion of the outboard motor mounting clamp.

Abstract: The roller assembly is utilized at the end of a turn in a turn chain assembly in a towveyor system. In the towveyor system a tow chain is guided and carried around the turn by a turn chain of the turn chain assembly. The roller assembly includes a non-rotatable stub shaft, a larger diameter, rotatable, hollow cylinder coaxial with the stub shaft, two axially spaced ball bearings rotatably mounting the cylinder on the shaft and a collar fixed on the cylinder for maintaining a tow chain at a desired height while it travels around the cylinder. A portion of the shaft extends axially beyond the cylinder for mounting the roller assembly in the turn chain assembly.
