  • Patent number: 5211345
    Abstract: 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.

  • Patent number: 5169277
    Abstract: A lift arm lock down apparatus for a load lifting vehicle is described. The vehicle has a vehicle body and a lift arm or boom rotatable between a raised and a lowered position about a horizontal pivot on the vehicle body. The lift arm lock down apparatus includes a lock having first and second cooperating lock members for selectively locking the lift arm to the vehicle body in the lowered position. The lock members are respectively mounted on the lift arm and the vehicle body. At least one lock member is movable by an appropriate manually or automatically operated mechanism between an unlocked position permitting tilting of the lift arm and a locked position where the lock members are releasably interconnected when the lift arm is at the lowered position. The lift arm lock down apparatus prevents accidental lifting of the lift arm, when the operator is entering or exiting the operator's compartment and may be used as a theft deterrent when the lift arm is locked in a lowered, ground engaging position.

  • Patent number: 5161934
    Abstract: The apparatus comprises a rectangular frame (20) disposed horizontally, which is fixed to the forks (25) of a lift truck. Gates (29) depend downwards from the sides of the frame, and each gate carries a pad (32). When the gates are operated hydraulically the pads clamp a pallet-sized layer (43) of cardboard cases (36) therebetween. Other layers of cases resting on the clamped layer may be picked up along with the clamped layer. The layer is clamped on all four sides, and the pads are long enough that no bottle (38) can "escape" the clamping force. The apparatus allows a high clamp force to be used, without the danger of damaging the cases or bottles.

  • Patent number: 5160091
    Abstract: 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.

  • Patent number: 5156506
    Abstract: 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.

  • Patent number: 5156518
    Abstract: 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.

  • Patent number: 5150999
    Abstract: Apparatus for lifting round bales of hay including a pair of arms which project forwardly from the front end of a tractor. These arms support a pivotal structure which includes a spear for impaling a round bale of hay and thereafter tilting the bale up off the ground. Another embodiment includes a device similarly attached to the forward end of a tractor; however, the latter embodiment involves a spear which can be elevated with respect to the ground while remaining parallel to the ground. A third embodiment involves a bale lifting device which is similar to the second embodiment but which can be attached to a conventional 3-point hitch on a tractor or to the rear of a flatbed trailer. A still further embodiment includes a square frame supported from a tractor by means of a 3-point hitch connection. The square frame rotatably supports an elongated rectangular frame which has impaling spears at the opposite ends thereof.

  • Patent number: 5151008
    Abstract: A substrate transfer apparatus includes two transfer arms pivotably arranged on a support table on opposite sides from each other with respect to a center of the support table. Each of the transfer arms includes: a first set of parallel links, a second set of parallel links, and a substrate holding member. The first set of the links is pivotably connected to the second set of the links at one ends thereof. The other ends of the first set of the links are pivotably connected to the support table. The substrate holding member is provided on the other end of the second set of the links. The each of the substrate holding members moves outward from the support table by stretching of the transfer arms and returns to the support table by bending of the transfer arms, and the transfer arms are bent in an opposite direction to each other with respect to the support table.
