ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to plumbing tools and more particularly pertains to a new motorized device for cutting and cleaning a piece of pipe for more quickly and efficiently working with piping.
2. Description of the Prior Art
The use of plumbing tools is known in the prior art. More specifically, plumbing tools 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. 4,238,867; 4,349,928; 5,829,142; 3,355,749; 3,774,255; and U.S. Pat. No. Des. 310,470.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new motorized device for cutting and cleaning a piece of pipe. The inventive device includes a housing that has a pair of opposite ends and at least one pair of protruding portions being formed on one of the ends. At least one motor that has a motor shaft is mounted in the housing. A power supply is mounted in the housing for selectively providing power to the motor and at least one switch is mounted on the housing for selectively providing power to the motor. At least one attachment is removably mounted on the motor shaft for engaging a pipe.
In these respects, the motorized device for cutting and cleaning a piece of pipe 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 more quickly and efficiently working with piping.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of plumbing tools now present in the prior art, the present invention provides a new motorized device for cutting and cleaning a piece of pipe construction wherein the same can be utilized for more quickly and efficiently working with piping.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new motorized device for cutting and cleaning a piece of pipe apparatus and method which has many of the advantages of the plumbing tools mentioned heretofore and many novel features that result in a new motorized device for cutting and cleaning a piece of pipe which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art plumbing tools, either alone or in any combination thereof.
To attain this, the present invention generally comprises a housing that has a pair of opposite ends and at least one, pair of protruding portions being formed on one of the ends. At least one motor that has a motor shaft is mounted in the housing. A power supply is mounted in the housing for selectively providing power to the motor and at least one switch is mounted on the housing for selectively providing power to the motor. At least one attachment is removably mounted on the motor shaft for engaging a 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 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 motorized device for cutting and cleaning a piece of pipe apparatus and method which has many of the advantages of the plumbing tools mentioned heretofore and many novel features that result in a new motorized device for cutting and cleaning a piece of pipe which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art plumbing tools, either alone or in any combination thereof.
It is another object of the present invention to provide a new motorized device for cutting and cleaning a piece of pipe which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new motorized device for cutting and cleaning a piece of pipe which is of a durable and reliable construction.
An even further object of the present invention is to provide a new motorized 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 motorized device for cutting and cleaning a piece of pipe economically available to the buying public.
Still yet another object of the present invention is to provide a new motorized 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 motorized device for more quickly and efficiently working with piping.
Yet another object of the present invention is to provide a new motorized device for cutting and cleaning a piece of pipe which includes a housing that has a pair of opposite ends and at least one pair of protruding portions being formed on one of the ends. At least one motor that has a motor shaft is mounted in the housing. A power supply is mounted in the housing for selectively providing power to the motor and at least one switch is mounted on the housing for selectively providing power to the motor. At least one attachment is removably mounted on the motor shaft for engaging a pipe.
Still yet another object of the present invention is to provide a new motorized device for cutting and cleaning a piece of pipe that reduces the likelihood of repetitive motion injuries caused from manually turning, cleaning and cutting devices in the prior art.
Even still another object of the present invention is to provide a new motorized device for cutting and cleaning a piece of pipe that can clean and cut all types and sizes of tubing and piping, such as, for example, one-quarter inch, three-eighths inch, one-half inch, five-eighths inch, three-quarters inch and one inch. The present invention is capable of cutting and cleaning, copper, aluminum, or plastic tubing.
These together with other objects of the invention, alon
