Street Or Curb Inlet For Surface Drainage Patents (Class 404/4)
  • Patent number: 10053382
    Abstract: An over grate filter for covering a grate and filtering storm water runoff is claimed and described. The over grate filter of the invention helps to control the flow of waterborne sediment and pollutants into the storm water grate, and it also serves to reduce the amount of sediment entering drainage systems. The invention may be fabricated from any filtration fabrics, including woven and non-woven fabrics. The selection of the specific filter fabric used in the invention depends on the anticipated storm water flow velocities, the anticipated pollutant volume and the expected maintenance schedule. The over grate filter of the invention may comprise multiple layers of filter material and a supporting inner core that enables the filter to lie flat on the storm water grate, providing improved wear resistance against foot and vehicle traffic and street sweeping activity over the prior art methods for filtering storm water.

  • Patent number: 10022653
    Abstract: A water catchment and lawn edging system includes a cap, a channeled drain fixture, and at least one base clip. The base clip, which connects the system to the ground surface, is connected to a bottom end of the channeled drain fixture. Depending upon the length or the profile of the channeled drain fixture, the system can utilize a single base clip or a plurality of base clips to properly support the system. The cap is continuously connected along the channeled drain fixture from a top end of the channeled drain fixture. The cap may include a plurality of drain openings to provide additional drainage for the system. Collectively, the cap, the channeled drain fixture, and the base clip function as a water catchment and lawn edging system so that surface and ground water can be drained and filtered away from a collecting area and discharged into an outfall.

  • Patent number: 9260853
    Abstract: A runoff water vault may be divided into an input chamber which receives runoff water and a second chamber which also separates and stores buoyant and non-buoyant materials separated from the runoff water stream. While the separators in such systems remove particles of different densities than water quite well, they have difficulty in removing neutrally buoyant debris. Screens are added into the water flow stream to catch and remove particles of neutral buoyancy. The screens are mounted in a manner which permits lateral movement of the screen relative to the water flow, such as shaking and/or flexing. Screen movement imparts pressure differential across the screen perforations releasing debris trapped against the screen, so that the debris will fall into an entrainment area and allow increased flow through the screen. The screens may also include one or more turbulator fins for intersecting the water flow and transferring energy to the screen, imparting lateral movement to the screen.

  • Patent number: 8591729
    Abstract: The storm drain with water trap is installed in the opening of a storm or sewer drain to close off the underlying drain channels and residual water therein from the open air, thus preventing escape of mold, mosquitoes, and other hazards into the air. The device has an insert having an open top and bottom. A shallow water trap pan is suspended below the insert. In dry conditions, the water trap contains little water, the relatively light weight of the trap and contained water allowing it to be lifted by springs against the bottom of the insert to form a seal. When runoff water flows into the drain, the greater amount of water and its weight draws the insert downward, extending the springs and opening a gap between the lower edge of the insert and the water trap pan to allow the runoff water to flow therethrough.

  • Patent number: 8277645
    Abstract: A screen system having first and second side members, each having a locking gear reversibly movable from a locked position to an unlocked position. A screen is coupled to the side members. The screen has openings and is rotatable from a closed position to an open position. The screen is engagable with the locking gears to preventing the screen from rotating from the closed position to the open position. A trigger plate is movably coupled to the screen, rotates from a first position to a second position and is engagable with the locking gears to prevent the locking gears from moving from the locked position to the unlocked position. The trigger plate disengages with the locking gears when water flows against it, allowing the locking gears to move from the locked position to the unlocked position and the screen to rotate from the closed position to the open position.

  • Patent number: 8272807
    Abstract: A surface drainage structure formed above a subgrade may include an elongate drain conduit disposed partially within the subgrade. The elongate drain conduit may define at least one drain slot extending through a wall thereof. The structure may include a pavement layer with an exposed top surface and a drainage channel extending therefrom. The drainage channel may be in fluid communication with the drain slot of the elongate drain conduit. A method of forming the surface drainage structure includes placing the elongate drain conduit in the subgrade, forming the pavement layer, cutting an upper channel along the elongate drain conduit, and cutting a lower channel and the drain slot in the elongate conduit.

  • Patent number: 8226824
    Abstract: The anti-clogging drainage inlet is adapted for use in lawn or field environments that require drainage systems to prevent flooding or unwanted pooling during periods of rain. The inlet includes a grate mounted to a rectangular frame. The frame and the grate are adapted to be positioned in the opening of a conventional drainage box in a manner that the top surface of the grate is flush with the surface of the lawn or field. A linkage system is mounted to the frame and grate and operates to raise the grate from its flush position. The linkage system includes a container positioned below the grate and within the drainage box.

  • Patent number: 8075219
    Abstract: An improved grate 601 is made from a plurality of elongate grate pieces 602, each grate piece 602 having a body 603 with a first end 604 and a second end 605. Each grate piece 602 has the first end 604 angled with respect to the body 603 and the second end 605 angled with respect to the body 603. When the first end 604 of a grate piece 602a is welded to the first end of an adjacent grate piece 602b, and the second end 605 of the grate piece 602a is welded to the second end of the adjacent grate piece 602b so as to form the grate 601, a gap is formed between the respective bodies of the grate pieces 602 to permit the drainage of liquid between the grate pieces. By varying the angles at which the grate pieces 602 are welded together sections of grate with both horizontal and vertical curvature can be formed.
