ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to waste water filtering systems and more particularly pertains to a new septic system filter apparatus for filtering waste water as it travels from a septic tank to a septic field.
2. Description of the Prior Art
The use of waste water filtering systems is known in the prior art. More specifically, waste water filtering systems heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. Nos. 5,387,335; 4,104,166; 4,710,295; 3,207,314; 3,156,646; and 5,382,257; 5,427,679; 5,558,763; 5,227,051; 4,818,384; 5,674,380; U.S. Pat. Des. No. 357,737.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new septic system filter apparatus. The inventive device includes a filtering system for filtering water from a septic tank for receiving waste material. A filtering apparatus comprises a first housing having a bottom wall and a top wall. The top wall is a removable lid. The first housing has a first inlet port and an exit port. The bottom wall has at least two supports thereon extending upward from an inner surface of the bottom wall. A second housing for holding filtering material has a removable lid thereon. The second housing has dimensions smaller than the first housing to fit into the first housing. A space is defined between the first housing and the second housing. The second housing rests on the supports above the inner surface of the bottom wall. The second housing has a second inlet port located generally adjacent to the first inlet port. The second housing has an upper chamber and lower chamber. A grill separates the upper and lower chambers. Filtering material covers the grill. An inlet pipe delivers fluid from the septic tank to the second housing. The inlet pipe extends through the first and the second inlet ports. An outlet pipe delivers fluid to a septic field from the interior of the first housing. The outlet pipe is fluidly connected to the outlet port in the first housing.
In these respects, the septic system filter apparatus according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of filtering waste water as it travels from a septic tank to a septic field.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of waste water filtering systems now present in the prior art, the present invention provides a new septic system filter apparatus construction wherein the same can be utilized for filtering waste water as it travels from a septic tank to a septic field.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new septic system filter apparatus apparatus and method which has many of the advantages of the waste water filtering systems mentioned heretofore and many novel features that result in a new septic system filter apparatus which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art waste water filtering systems, either alone or in any combination thereof.
To attain this, the present invention generally comprises a filtering system for filtering water from a septic tank for receiving waste material. A filtering apparatus comprises a first housing having a bottom wall and a top wall. The top wall is a removable lid. The first housing has a first inlet port and an exit port. The bottom wall has at least two supports thereon extending upward from an inner surface of the bottom wall. A second housing for holding filtering material has a removable lid thereon. The second housing has dimensions smaller than the first housing to fit into the first housing. A space is defined between the first housing and the second housing. The second housing rests on the supports above the inner surface of the bottom wall. The second housing has a second inlet port located generally adjacent to the first inlet port. The second housing has an upper chamber and lower chamber. A grill separates the upper and lower chambers. Filtering material covers the grill. An inlet pipe delivers fluid from the septic tank to the second housing. The inlet pipe extends through the first and the second inlet ports. An outlet pipe delivers fluid to a septic field from the interior of the first housing. The outlet pipe is fluidly connected to the outlet port in the first housing.
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 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 description 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.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new septic system filter apparatus apparatus and method which has many of the advantages of the waste water filtering systems mentioned heretofore and many novel features that result in a new septic system filter apparatus which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art waste water filtering systems, either alone or in any combination thereof.
It is another object of the present invention to provide a new septic system filter apparatus which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new septic system filter apparatus which is of a durable and reliable construction.
An even further object of the present invention is to provide a new septic system filter apparatus 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 septic system filter apparatus economically available to the buying public.
Still yet another object of the present invention is to provide a new septic system filter apparatus which provides in the apparatuses and methods of the prior art some of the advant
