ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to oil recovery devices and more particularly pertains to a new oil recovery device for removing oil lining the interior of oil containers.
2. Description of the Prior Art
The use of oil recovery devices is known in the prior art. More specifically, oil recovery devices 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. 5,477,897; 4,832,095; 5,636,670; U.S. Des. Pat. No. 389,381; U.S. Pat. Nos. 5,080,150; and 5,269,354.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new oil recovery device. The inventive device includes a housing having a bottom wall, a back wall, a top wall, a front wall, a first side wall, and a second side wall. The front wall has a plurality of elongate openings therein extending between the first and second side walls. Each of the openings has a generally rectangular shape such that each of the openings has a bottom edge. A plurality of drawers each has a base wall, a facing wall, a rear wall, and a pair of lateral side walls. The drawers have a plurality of compartments therein. The drawers are each positioned in one of the openings. Each of the facing walls has a bottom edge hingedly coupled to and extending along one of the bottom edge of the associated opening such that each of the rear walls may be abutted against the back wall of the housing when the drawer is in a closed position. Each of the base walls has a pipe attached thereto. The pipes are in communication with the compartments of the attached drawer. A tube is fluidly coupled to the housing and extends into the bottom wall. Each of a plurality of oil containers may be positioned in one of the compartments such that oil within the oil containers may be drained into the pipes. The oil may then be removed from the housing through the tube.
In these respects, the oil recovery device 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 removing oil lining the interior of oil containers.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of oil recovery devices now present in the prior art, the present invention provides a new oil recovery device construction wherein the same can be utilized for removing oil lining the interior of oil containers.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new oil recovery device apparatus and method which has many of the advantages of the oil recovery devices mentioned heretofore and many novel features that result in a new oil recovery device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art oil recovery devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises a housing having a bottom wall, a back wall, a top wall, a front wall, a first side wall, and a second side wall. The front wall has a plurality of elongate openings therein extending between the first and second side walls. Each of the openings has a generally rectangular shape such that each of the openings has a bottom edge. A plurality of drawers each has a base wall, a facing wall, a rear wall, and a pair of lateral side walls. The drawers have a plurality of compartments therein. The drawers are each positioned in one of the openings. Each of the facing walls has a bottom edge hingedly coupled to and extending along one of the bottom edge of the associated opening such that each of the rear walls may be abutted against the back wall of the housing when the drawer is in a closed position. Each of the base walls has pipe attached thereto. The pipes are in communication with the compartments of the attached drawer. A tube is fluidly coupled to the housing and extends into the bottom wall. Each of a plurality of oil containers may be positioned in one of the compartments such that oil within the oil containers may be drained into the pipes. The oil may then be removed from the housing through the tube.
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 oil recovery device apparatus and method which has many of the advantages of the oil recovery devices mentioned heretofore and many novel features that result in a new oil recovery device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art oil recovery devices, either alone or in any combination thereof.
It is another object of the present invention to provide a new oil recovery device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new oil recovery device which is of a durable and reliable construction.
An even further object of the present invention is to provide a new oil recovery device 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 oil recovery device economically available to the buying public.
Still yet another object of the present invention is to provide a new oil recovery device which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new oil recovery device for removing oil lining the interior of oil containers.
Yet another object of the present invention is to provide a new oil recovery device which includes a housing having a bottom wall, a
