ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a wood-stove smoke controller and more particularly pertains to a new woodstove emission controller for conveniently drawing emissions from the wood-stove so that the emissions do not enter the room where the wood-stove is located.
2. Description of the Prior Art
The use of wood-stove smoke controller is known in the prior art. More specifically, wood-stove smoke controller 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. 4,280,476; 4,510,854; 4,424,799; 4,708,123; U.S. Pat. No. Des. 266,867; and U.S. Pat. No. 4,469,284.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new woodstove emission controller. The inventive device includes a tubular member having an inlet end, an outlet end and a bore extending therethrough; and also includes a closure member securely disposed in the bore near the outlet end for preventing a back-draft of emissions; and further includes a fan member securely and rotatably disposed in the bore for drawing emissions in through the inlet end and out through the outlet end of the tubular member; and also includes a motor mounted to the exterior of the tubular member, a belt member carried by the motor and the fan member, and a switch for energizing the motor.
In these respects, the woodstove emission controller 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 conveniently drawing emissions from the wood-stove so that the emissions do not enter the room where the wood-stove is located.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of wood-stove smoke controller now present in the prior art, the present invention provides a new woodstove emission controller construction wherein the same can be utilized for conveniently drawing emissions from the wood-stove so that the emissions do not enter the room where the wood-stove is located.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new woodstove emission controller which has many of the advantages of the wood-stove smoke controller mentioned heretofore and many novel features that result in a new woodstove emission controller which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art wood-stove smoke controller, either alone or in any combination thereof.
To attain this, the present invention generally comprises a tubular member having an inlet end, an outlet end and a bore extending therethrough; and also includes a closure member securely disposed in the bore near the outlet end for preventing a back-draft of emissions; and further includes a fan member securely and rotatably disposed in the bore for drawing emissions in through the inlet end and out through the outlet end of the tubular member; and also includes a motor mounted to the exterior of the tubular member, a belt member carried by the motor and the fan member, and a switch for energizing the motor.
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 woodstove emission controller which has many of the advantages of the wood-stove smoke controller mentioned heretofore and many novel features that result in a new woodstove emission controller which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art wood-stove smoke controller, either alone or in any combination thereof.
It is another object of the present invention to provide a new woodstove emission controller which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new woodstove emission controller which is of a durable and reliable construction.
An even further object of the present invention is to provide a new woodstove emission controller 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 woodstove emission controller economically available to the buying public.
Still yet another object of the present invention is to provide a new woodstove emission controller 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 woodstove emission controller for conveniently drawing emissions from the wood-stove so that the emissions do not enter the room where the wood-stove is located.
Yet another object of the present invention is to provide a new woodstove emission controller which includes a tubular member having an inlet end, an outlet end and a bore extending therethrough; and also includes a closure member securely disposed in the bore near the outlet end for preventing a back-draft of emissions; and further includes a fan member securely and rotatably disposed in the bore for drawing emissions in through the inlet end and out through the outlet end of the tubular member; and also includes a motor mounted to the exterior of the tubular member, a belt member carried by the motor and the fan member, and a switch for energizing the motor.
Still yet another object of the present invention is to provide a new woodstove emission controller that safeguards against fumes from the wood-stove from getting into the user's house.
Even still another object of the present invention is to provide a new woodstove emission controller that can be easily and quickly installed in
