  • Multi-conveyor system
    Patent number: 6739445
    Abstract: A conveyor system for transitioning articles between an external intermittent conveyor and an external continuous conveyor system includes an upper conveyor and lower conveyor. Each conveyor includes an infeed arm movable toward and away from the intermittent conveyor. Each infeed arm defines an infeed end that is movable along a common arc and rotatable about a common pivot point. With the infeed ends traveling along a common arc, each infeed end is easily moved to the same optimal receiving position for receiving articles from the intermittent conveyor. Each conveyor may switch between a continuous mode, wherein articles are continuously discharged onto the continuous conveyor, and an intermittent mode, wherein articles are intermittently received from the intermittent conveyor.

  • Axle crutch
    Patent number: 6279950
    Abstract: The invention provides an improved temporary support device for multiple axle trailers with leaf spring suspension regardless of frame design. The device provides emergency towing capabilities to a trailer that would otherwise be immobile due to the failure of a spindle, bearings, spring, tire, suspension, wheel or other suspension or wheel component attached to an axle. The detachable device comprises a steel tube which extends between two leaf spring shackles and is held in place by two locking pins, a length of chain to secure the disabled axle to the steel tube, and a protective shield and locking pin to secure the chain to the steel tube. The steel tube has multiple holes to adjust the device to fit any multiple axle trailer.
