ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mechanical boot system and more particularly pertains to positioning an expanding section in a mechanical type boot system to allow settling in the subgrade of landfill as the refuse deteriorates without damage to the boot or liner.
2. Description of the Prior Art
The use of land fill systems and equipment of known designs and configurations is known in the prior art. More specifically, land fill systems and equipment of known designs and configurations heretofore devised and utilized for the purpose of attending to land fill systems in a safe and cost effective manner through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 5,863,152 to Ingalls discloses a mechanical gas vent. Further, U.S. Pat. No. 5,120,161 to Faussone discloses an apparatus for the controlled disposal of waste and method therefor.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a mechanical boot system that allows positioning an expanding section in a mechanical type boot system to allow settling in the subgrade of landfill as the refuse deteriorates without damage to the boot or liner.
In this respect, the mechanical boot system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of positioning an expanding section in a mechanical type boot system to allow settling in the subgrade of landfill as the refuse deteriorates without damage to the boot or liner.
Therefore, it can be appreciated that there exists a continuing need for a new and improved mechanical boot system which can be used for positioning an expanding section in a mechanical type boot system to allow settling in the subgrade of landfill as the refuse deteriorates without damage to the boot or liner. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of land fill systems and equipment of known designs and configurations now present in the prior art, the present invention provides an improved mechanical boot system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved mechanical boot system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a mechanical boot system including an expandable section which allows settling in the subgrade of a landfill as the refuse deteriorates without damage to the boot or the liner. A vertically positioned riser in a tubular configuration is fabricated of high density polyethylene plastic with a height of about 2.5 feet. The riser has an outwardly flanged upper end and an outwardly flanged lower end. Vertical bolt holes extend through the ends. A high density polyethylene base flange has a lower flat end welded to a refuse liner and is provided with vertical threaded bolt holes. A rubber seal is positioned between the lower surface of the lower end of the riser and the upper end of the base flange. Vertically extending bolts are provided and extend through bolt holes for coupling between the riser, seal and base flange. A split seal cap ring in a generally cylindrical configuration has a flanged lower end with vertical threaded bolt holes and an interior annular recess. A rubber O-ring is located within the interior annular recess. An exterior recess has a rectangular cross-section. A stainless steel band is located around the exterior recess. A bolt is provided for tightening purposes. An inverted J-shaped tube constitutes a gas well pipe. The tube has a long vertical section located within the split seal cap ring. The vertical section extends upwardly then outwardly in an intermediate section and downwardly in an outboard section for the exhaust of gasses. The lowermost end of the gas well pipe is held in a fluid type relationship with regard to the split seal cap ring through the application of forces of the O-ring as effected by the tightening of the band. Lastly provided is an intermediate expandable bellows. The bellows is in a vertical orientation and has an upper horizontal flange. Vertical apertures are aligned with the holes in the flanged lower end of the split seal cap ring. Securement bolts are provided. The lower end of the bellows has a lower horizontal flange with vertical holes aligned with the holes at the upper end of the riser and coupling bolts are provided. The intermediate extent of the bellows is formed with flexible undulations to allow its contraction under the force or gravity and its expansion under the force of gasses from beneath the liner tending to escape upwardly through the base flange, riser, bellows, split seal cap ring and gas well pipe.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved mechanical boot system which has all of the advantages of the prior art land fill systems and equipment of known designs and configurations and none of the disadvantages.
It is another object of the present invention to provide a new and improved mechanical boot system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new and improved mechanical boot system which is of durable and reliable construction.
An even further object of the present invention is to provide a new and improved mechanical boot system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such mechanical boot system economically available to the buying public.
Even still another object of the present invention is to provide a mechanical boot system for positioning an expanding section in a mechanical type boot system to allow settling in the subgrade of landfill as the refuse deteriorates without damage to the boot or liner.
Lastly, it is an object of the present invention to provide a new and improved mechanical type boot including a vertically positioned riser in a tubular configuration with an outwardly flange
