Abstract: A septic leach line control apparatus comprising a hollow housing with tapered continuous sidewalls extending from a top to a wider base at the bottom. The hollow housing includes a flange extending outwardly from the base and a wider inner flange extending inwardly from the base within the housing. The inner flange defines a vertical elongated opening conformed to engage a pipe or similarly configured conduit, which has a top end and a bottom end. Also provided is a gate valve assembly, including a gate valve, a gate valve housing, and a gate valve handle assembly with a handle attached to an elongated rod at one end and to the gate valve at the other end. The rod with the attached handle extends through the pipe into the hollow housing. The bottom end of the pipe at least partially, if not entirely, encloses the gate valve assembly, or at the very least, the uppermost section of the gate valve housing.

Abstract: A clamping assembly for securing the canopy of a retractable awning mounted on a recreational vehicle, including one or more clamp members, each having a top section and a bottom section positioned in face opposed relation with each section having a back surface and a front surface. Each back surface includes a protruding member with an opening adapted, when aligned, to receive a means to attach the clamp member to support arms. The front surfaces form a pair of projecting face opposed clamping flanges with a space in between the two to engage the canopy material. Also provided is a pair of spring-loaded lever arms adapted for pivotal movement between a vertical position to enable the flanges to engage the canopy material in a releasable grip and a horizontal position to enable the flanges to separate and release their grip on the canopy. Rotating the lever arms in opposite directions act to adjust the tightness of the grip the flanges have on the canopy material.

Abstract: A rotatable coupling assembly for facilitating the connection and separation of a waste discharge hose between a recreational vehicle waste discharge outlet and the inlet of an external waste disposal receptacle, including a first coupling with a first fitting having a generally cylindrical main body with a flanged portion. A second fitting is also provided and is adapted to slide along the main body until it approaches the first fitting. The second fitting has radial projections for lockingly engaging corresponding hook-like members of a mating fitting of a second coupling, or the converse. A similarly structured third or mating fitting is also provided. A flanged ring member with an annular seating surface joins with one end of the discharge hose to enable the mated components to be slidably disposed along the main body until they approach the second fitting.

Abstract: An apparatus for attaching and securing a cap to a hose adapter used in connection with an RV waste removal valve assembly to prevent inadvertent sewer or waste spillage in the event of a failure of the primary locking components. The apparatus comprises two principal components, including a Y-branch plumbing fitting with a hose adapter incorporated at one end. On the outside surface of the hose adapter are a coupling pin and an adjacently located coupling tongue. The other component is a closure cap, which includes one or more generally L-shaped coupling arms. The coupling arms form a U-shaped opening with the edge of the cap and include an opening at one end to slidably receive the coupling pin and a grooved or slotted portion along the base of the coupling arm near where the arm attaches to the edge of the cap to slidably receive the coupling tongue.

Abstract: A gate valve having a valve housing with an upper housing member, and a lower housing member, which contains a flow passageway. A valve closure device with a valve stem is moveable transversely of the flow passageway between the upper housing member, to cause the passageway to open, and the lower housing member, to cause the passageway to close. An axially moveable sleeve covered cable, which is connected to the valve closure device at the valve stem, is provided to impart movement to the valve closure device. A clamp assembly which includes identical cooperating members adapted to align in opposing relationship to engage and secure the upper housing and the cable and cable sleeve between them enables the cable to be operated from a remote and convenient location outside the recreational vehicle at any desired angle of bend to engage the valve closure device to cause it to move easily and effectively back and forth within the valve housing.

Abstract: An apparatus for attaching and securing a drain hose to the adapter used with a recreational vehicle ("RV") waste drain assembly or, at the opposite end of the hose, to a sewer fitting used in conjunction with a septic tank or some other type of in or above ground sewer system for receiving drained waste matter. The apparatus comprises a retaining ring, which may include an annular flange formed along one edge, slidably mountable inside the opening at one end of a RV drain hose, for retaining the shape and requisite diameter dimension of the end section of the hose to facilitate its engagement with the adapter or the sewer fitting when those connections are made. The ring is removed before the adapter or the sewer fitting engages the hose opening to enable the hose to contract and form a tight seal with those components.
