  • Publication number: 20200256489
    Abstract: An irrigation pipe and method of fabrication that utilizes a pipe that is made of a durable material, e.g., stainless steel or aluminum. During fabrication, the pipe is equipped with a plurality of components, i.e., a flange assembly, a truss mount, and an outlet, without drilling, welding, or the like. In this manner, a method of fabrication is provided that enables a plurality of components to be assembled to the pipe without compromising the integrity of the pipe material or treated surface so that galvanizing or painting is not required after the plurality of components have been fitted to the pipe.

  • Patent number: 10710110
    Abstract: An outlet fitting broadly comprises a coupler, a plug, and a gasket. The coupler engages a conduit opening of a conduit and includes an aft section, a forward section, and a radially extending flange bisecting the aft and forward sections. The aft section includes a narrowing inner surface forming a fluid passageway. The flange includes an upper surface for abutting the conduit near the conduit opening. The plug has a laterally elongated longitudinally extending central aperture. The aft section is inserted into the conduit opening and a tool inserted into the central aperture draws the plug towards the forward section and expands the aft section into secure engagement with the conduit. The gasket is also urged against the periphery of the conduit opening and forms a seal between the coupler and the conduit.

  • Patent number: 10525773
    Abstract: A wheel assembly comprising a rigid wheel including a radially outer rim wall presenting a polygonal shape with a plurality of outermost vertices connecting a plurality of planar faces, and a flexible tire mounted on the outer rim wall. The tire is supported by the vertices of the rim wall and is separated from the rim faces by a space, portions of the tire located between the vertices being configured to flex inwardly when subject to ground engaging pressure.

  • Publication number: 20190143757
    Abstract: An airless flexible tire including traction lug pairs each having a forward facing traction lug and a rearward facing traction lug cooperatively forming a divided Z or reverse divided Z shape. Each traction lug includes a lateral section and a central section. The central section extends from an end of the lateral section so as to straddle a centerline of the airless flexible tire and includes a number of discrete sidewalls. The discrete sidewalls are different sizes and angled relative to each other. The central sections of paired traction lugs form a space dividing portions of the Z or reverse Z shape. The central sections of nearest traction lugs of adjacent traction lug pairs form a space dividing the adjacent traction lug pairs.

  • Publication number: 20180363833
    Abstract: A pipe liner for lining a fluid-carrying pipe, the pipe liner comprising an elongated flexible conduit and a flexible flange. The flexible conduit includes an outer wall forming an open-ended central channel for allowing fluids to be pumped therethrough. The flexible flange extends radially from one end of the elongated conduit and includes a number of fastener holes. The flexible conduit and the flexible flange are configured to be collapsed and pulled through the pipe such that the flexible flange can be connected to a rigid flange of the pipe via the fastener holes. The pipe liner is less prone to leak and is easier to transport and install.

  • Patent number: 10137735
    Abstract: A wheel assembly includes a rigid wheel and an airless flexible tire with certain performance characteristics of a pneumatic tire. The rigid wheel includes a central portion and a plurality of circumferentially spaced mounting elements removably attached to a radially outer margin of the central portion. The tire is mounted on the wheel and engages the mounting elements such that portions of the tire not engaging the mounting elements are separated radially from the wheel by a space. The tire is configured such that portions of the tire not engaging the mounting elements flex inwardly toward the wheel when subject to ground engaging pressure, thereby minimizing ground penetration and soil disruption. The tire may include one or more tension elements embedded in the tire to increase the tire's strength and resilience.

  • Patent number: 10139017
    Abstract: A suspended pipe assembly comprising a first suspended pipe, a second suspended pipe, a third suspended pipe, and a number of suspenders for suspending the pipes from an elevated pipe or pipes of a mobile irrigation system or other fluid distribution system. The first suspended pipe and second suspended pipe are connected together via a fixed joint. The second suspended pipe and third suspended pipe are connected together via a live joint such that the second suspended pipe and third suspended pipe can expand longitudinally relative to each other. Additional suspended pipes can be connected to each other via alternating fixed and live joints. The suspenders allow the suspended pipes to expand longitudinally relative to the elevated pipe and prevents the suspended pipes from warping side-to-side.

  • Patent number: 9950567
    Abstract: A wheel assembly includes a collapsible wheel and an airless flexible tire mounted on the wheel. The wheel includes a central portion and a plurality of circumferentially spaced mounting elements attached to the central portion. Each of the mounting elements is movable between a retracted position and an extended position, and may be pivotally attached to the central portion of the wheel and configured to pivot between the retracted position and the extended position. The tire may be positioned on the wheel when one or more of the mounting elements is in the retracted position, and the one or more mounting elements are moved to the extended position wherein the mounting elements engage and support the tire.
