  • Patent number: 11678641
    Abstract: A hinge locking system is provided for locking pivotable hinge parts at a desired angular position relative to one another. The hinge locking system includes a locking pin, a plate with a locking pin receiver, a movable pin receiver defining an axial bore for receiving the locking pin, and a pair of spaced-apart limit stops along the plate. The movable pin receiver is movable relative to the plate, and the limit stops are selectively contacted by the movable pin receiver to limit the maximum relative movement of the movable pin receiver. When the axial bore of the movable pin receiver aligns with the plate's locking pin receiver, the locking pin is insertable through the locking pin receiver and the axial bore in the movable pin receiver, to thereby lock the movable pin receiver and the hinge parts against further movement.

  • Patent number: 10568297
    Abstract: A livestock living quarter for a transport trailer, such as a livestock trailer, provides livestock stalls and mangers inside the trailer. The living quarter includes at least one stall for a livestock animal, the stall defined by a chest wall, an interior wall, and a front wall set parallel to the interior wall. A second stall may be provided, with the interior wall of the first stall providing a divider wall between the first and second stalls, and acting as a front wall of the second stall. The stall divider may be pivotable to allow for entry of a livestock animal into the stall. A manger is disposed in front of the stall for storage of feed that is accessible to the livestock animal in the stall. Optionally, a water trough is accessible at the manger, and other spaces may provide living quarters or facilities for an operator.

  • Patent number: 10405516
    Abstract: A deployable corral system for a transport trailer, such as a livestock trailer, provides a readily deployable corral along the trailer, and is readily stowable along the trailer in a retracted configuration for travel. The corral includes a pair of spaced-apart and extendable corral rails with a cross-rail extending between distal ends of the extendable corral rails. When the extendable corral rails are extended the cross-rail is spaced from an exterior side of the livestock trailer, and when the extendable corral rails are retracted the cross-rail is positioned near a roof of the trailer. The extendable corral rails move between the extended and retracted positions manually, or automatically with a drive system. Optionally, the drive system is powered by motors associated with linear or rotary actuators. Further options may include storage bins along the cross-rail, a deployable shade awning, a deployable trough, jack stands, securing flaps, and position sensors.

  • Patent number: 7399139
    Abstract: A device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at two locations by height adjustment mechanisms that raise and lower the two locations of the contouring assembly independently of each other. The contouring assembly creates a three-dimensionally curved surface as it passes over an area to be contoured. The control of at least one location of the contouring assembly is based on a comparison of the measured position of one portion of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. Control of the height of the other location is preferably based on the height above a physical reference measured with a proximity sensor. A pivot or tilting controller may control the tilting of the contouring assembly to follow the slope of the profile stored in computer memory.

  • Patent number: 7144191
    Abstract: A contouring machine control system, contouring/smoothing method, and kit for enabling a contouring machine to automatically contour three-dimensional surfaces includes a contouring member, such as a screed or dirt grading blade, a target either attached to the contouring member or located at a remote location, a tracking device at the other of the contouring member or remote location that tracks the target and measures the position of the target in three dimensions, a proximity sensor adjacent one end of the contouring member to detect its height above a physical reference, and a controller/computer for controlling the height of the two ends of the contouring member. One of the ends is controlled as a function of a stored profile of the desired surface to be contoured and the target or tracking device position, while the second end is controlled as a function of the current height of the proximity sensor above the reference.

  • Patent number: 6929420
    Abstract: A device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at opposite ends by height adjustment mechanisms. The height adjustment mechanisms raise and lower the ends of the contouring assembly independently of each other, thereby allowing the contouring assembly to create a three-dimensionally curved surface as it passes over an area to be contoured. The control of at least one end of the contouring assembly is based on a comparison of its measured position with a profile of the surface to be leveled that is stored in a computer memory.

  • Patent number: 6623208
    Abstract: A concrete placing apparatus is provided for placing uncured concrete on a support surface, such as an elevated deck of a building. The apparatus comprises a base unit and a movable support, with a conduit assembly extending therebetween. A supply end of the conduit assembly is positioned at the base unit and is connected to a supply line for uncured concrete or other material, while a dispensing end of the conduit assembly is supported by the movable support and extends outwardly therefrom to dispense uncured concrete or other material through a discharge outlet. The movable support is movable arcuately and/or radially relative to the base unit to dispense the concrete in a generally uniform manner over a targeted area. The apparatus may further include a screeding device at the discharge outlet to grade, level, compact and smooth the concrete as it is placed.

  • Publication number: 20020098039
    Abstract: A contouring device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at opposite ends by a pair of fluid cylinders. The fluid cylinders are controlled to raise and lower the ends of the contouring assembly independently of each other, thereby allowing the contouring assembly to create a three-dimensionally curved surface as it passes over an area to be contoured. The control of one of the fluid cylinders is based on a comparison of the measured position of a first end of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. The measurement of the position of the first end of the contouring assembly is achieved by a tracking device which tracks the position of a target positioned on the first end of the contouring assembly and which determines the three dimensional position of the target.
