Patent number: 8647044Abstract: The light-weight live-floor module has a floor surface, parallel cables laid on the floor surface, a length of conveyor belt laid on the cables, a movable bulkhead and a winch system for moving the belt, the cables and the bulkhead back and forth in unison, such as a shuttle. The belt has just enough length to cover the return axis and the floor surface on which goods are transported, thereby reducing any unnecessary weight in the live floor structure. The cables and the belt are wrapped over different axes for eliminating relative movement between the cables and the belt. One axis is set higher than the floor surface for easily breaking static friction under the belt. In a method for breaking static friction between a conveyor belt and a floor surface, a first segment of the belt is jolted upwardly while tension is applied in the belt.Type: GrantFiled: May 3, 2012Date of Patent: February 11, 2014Inventors: Harvey Stewart, Darrin Mitchell

Patent number: 7320572Abstract: An apparatus and method to facilitate unloading material from the cargo area (e.g. bed) of a vehicle. The apparatus may include a flexible member placed to line the bottom of the cargo area before a load is placed therein. After moving the vehicle to a desired location, a friction-reducing member may be placed to extend across the rear edge of the cargo area (e.g. the rear edge of an open tailgate). One end of the flexible member may be wrapped around the friction-reducing member and placed just behind the rear wheels of the vehicle. The vehicle may then be moved in reverse. The wheels of the vehicle roll over the flexible material, fixing one end thereof to the ground. The friction reducing member acts like a pulley (whether rolling with, or simply sliding with respect to, the flexible member) at the edge of the moving tailgate, drawing the flexible member and associated load out of the cargo area of the vehicle.Type: GrantFiled: January 20, 2004Date of Patent: January 22, 2008Inventor: Fred P.

Patent number: 4629390Abstract: A device which unloads materials from a vehicle cargo area such as the bed of a pickup truck. A pair of mounting brackets are bolted to opposite sides of the vehicle bed. Pivoted to the brackets are the front ends of rigid frame arms which carry a rotatable drum between their back ends. A flexible conveyor sheet is wound on the drum and can be unwound onto the vehicle bed to receive materials loaded therein. A motor driven or manually operated drive system rotates the drum to unload the cargo as the conveyor sheet is wound up on the drum. The pivotal mounting of the frame arms permits them to be raised with the tailgate of the vehicle to a storage position during transport of the load.Type: GrantFiled: October 31, 1984Date of Patent: December 16, 1986Inventor: Donald D.

Patent number: 4339884Abstract: A novel apparatus and method are provided for drying or otherwise processing fish. The apparatus includes a generally prone or slightly sloped frame having an upper perforated bed or flake and a lower pair of parallel tracks or rails. An upright framework is disposed at one end of the frame and is adapted to run along the tracks or rails from that one end to the opposite end. A roller mechanism including a round or polygonal roller is rotatably and preferably removably mounted in the upright framework. A mesh material is secured at one end to the roller mechanism and is extended along the flake and is secured to the opposite end of the frame. Means are provided for simultaneously moving the upright framework along the rails from the one end of the frame to the opposite end of the frame while winding the mesh material on the roller mechanism.Type: GrantFiled: November 5, 1980Date of Patent: July 20, 1982Inventor: Donald Andrews
