Patent number: 5211345Abstract: A system for handling bales of feed includes a freight trailer with a tongue that can be offset laterally to cause the trailer to follow a path to one side of the path of a tractor to permit a front-loading device on the trailer to engage bales of feed and raise them onto a load-carrying platform of the trailer. The platform is tiltable downward to the rear to induce sliding movement of loaded bales, and to release said bales in a vertical stack. The platform is provided with a device to grip the top bale of a stack and insert a lifting member under the stack to retrieve it for feeding operations. The platform is tiltable downward-forward to induce forward movement of the bales for release onto a bale shredder carried in part on the tongue of the trailer.Type: GrantFiled: July 23, 1990Date of Patent: May 18, 1993Inventor: Charles Siebenga

Patent number: 5160091Abstract: A toy vehicle track with toy vehicles having an electric drive motor disposed in the chassis thereof. The track is formed of segments which are connected by plugging together. The electric drive motor in the vehicles is supplied with electricity via collectors and conductors placed in the track for uninterrupted operation over a period of time. When electrical connection with a net fails or is terminated, the vehicles can be operated over a further preset length of time. The segments are removably or fixedly connected with conductors along the entire track. The vehicles have collectors in contact with the conductors and a chargeable power source serving as an electric buffer. The power source and the collectors are simultaneously in permanent connection with the drive motor. If the power supply is cut off from the electric net, the internal power source is automatically activated, and permits further operation until discharged.Type: GrantFiled: September 4, 1991Date of Patent: November 3, 1992Inventor: Kurt Hesse

Patent number: 5156506Abstract: A load tie-down and arrangement for securing loads onto vehicles, particularly non-uniform and abrasive loads such as logs onto log-hauling trailers, and for enhancing the safety with which such loads can be transported. The tie-down includes a high abrasion resistant webbing capable of being attached at one end to the vehicle and at the other to a winching mechanism. The winching mechanism easily accommodates excess webbing for small load situations and is capable of being easily and quickly tightened or retightened during transport to offset any slack in the webbing which may have been created due to load shifting or settling. A modified tie-down can be used to encircle the load without attachment to the vehicle for increased security.Type: GrantFiled: November 30, 1990Date of Patent: October 20, 1992Assignee: Greenhead IndustriesInventor: Warner Bailey

Patent number: 5156518Abstract: An unloading device having a frame transversely supportable on a pair of spaced side walls of a truck bed is longitudinally movable from the front to the rear of the truck bed. A plurality of wheels secured to the frame and engagable with the side walls facilitate movement of the device. An electric motor or hand crank is drivingly connected to a main shaft mounted on the frame for rotating the shaft in opposite directions, and an elongated sheet of material, such as reinforced nylon, having one end thereof secured to the shaft and the other end thereof secured to the rear of the truck bed is used for receiving an article for transportation. Rotation of the shaft in one direction winds the sheet of material on the shaft, moves the frame toward the rear of the truck bed and shifts the article on the sheet from the front of the truck bed to the rear and off of the truck bed. A rail is mounted on each of the side walls of the truck bed for guiding the wheels.Type: GrantFiled: February 21, 1991Date of Patent: October 20, 1992Assignee: Michael E.
