  • Patent number: 9631355
    Abstract: A septic drainage system includes a vehicle that has a septic tank and the septic tank has an outlet. A hose is selectively fluidly coupled to the outlet. Thus, the hose may drain the septic tank. The hose has a distal end with respect to the outlet. The distal end may be fluidly coupled to an inlet of a sewer thereby facilitating the septic tank to drain into the sewer. A supporting unit is provided and the supporting unit may be positioned on a support surface. The hose is positioned on the supporting unit such that the hose is inhibited from becoming uncoupled from the outlet and the sewer. Thus, the supporting unit enhances draining the septic tank.

  • Patent number: 8657072
    Abstract: The design is for a sawhorse with a collapsible support platform to support material that is being cut-off or worked on. The support platform keeps the material that is being cut from falling and/or splintering at the end of the cut and reduces or eliminates the need for an addition person to support the portion of the material being cut-off or for the person doing the cutting to attempt to hold the material being cut-off with one hand while cutting with the other and creating an unsafe condition. The sawhorse with support platform does not necessarily eliminate the need for a second sawhorse to support the opposite end of the material being cut or worked on. The sawhorse can be provided with the platform on both sides to provide additional cutting or material support surface which may then eliminate the need for a second sawhorse. Additionally the cutting support platform can be provided as a separate accessory that can be mounted to various manufactures' available sawhorses.
