ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to sill cock removal devices and more particularly pertains to a new frost proof sill cock extraction tool for removing a broken sill cock.
2. Description of the Prior Art
The use of sill cock removal devices is known in the prior art. More specifically, sill cock removal 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. No. 612,489; U.S. Pat. No. 1,364,496; U.S. Pat. No. 1,412,235; U.S. Pat. No. 3,914,966; U.S. Pat. No. 4,630,347; and U.S. Des. Pat. No. 317,214.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new frost proof sill cock extraction tool. The inventive device includes a bar. The bar is elongate and has a distal end and a proximal end. A peripheral wall extends between and is integrally coupled to the distal and proximal ends. The bar is generally hollow and has a hole extending through the distal and proximal ends. An outer surface of the peripheral wall positioned adjacent to the distal end is knurled. The bar has a break therein located generally adjacent to the distal end such that a first portion and a second portion of the bar is defined. The first portion abuts the distal end. The break extends from the peripheral wall to a point generally adjacent to the distal end in an angular relationship to a longitudinal axis of the bar. An inside surface of the first portion is threaded. A rod is elongate and has a first end and a second end. The rod has a threaded outer surface. The rod is extendably positioned through the first portion and is threadably couplable to the first portion. Rotating the rod in a first direction urges the first portion toward the second portion such that the first and second portions define an expansion bolt. The rod has a length greater than the bar.
In these respects, the frost proof sill cock extraction tool 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 a broken sill cock.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of sill cock removal devices now present in the prior art, the present invention provides a new frost proof sill cock extraction tool construction wherein the same can be utilized for removing a broken sill cock.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new frost proof sill cock extraction tool apparatus and method which has many of the advantages of the sill cock removal devices mentioned heretofore and many novel features that result in a new frost proof sill cock extraction tool which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art sill cock removal devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises a bar. The bar is elongate and has a distal end and a proximal end. A peripheral wall extends between and is integrally coupled to the distal and proximal ends. The bar is generally hollow and has a hole extending through the distal and proximal ends. An outer surface of the peripheral wall positioned adjacent to the distal end is knurled. The bar has a break therein located generally adjacent to the distal end such that a first portion and a second portion of the bar is defined. The first portion abuts the distal end. The break extends from the peripheral wall to a point generally adjacent to the distal end in an angular relationship to a longitudinal axis of the bar. An inside surface of the first portion is threaded. A rod is elongate and has a first end and a second end. The rod has a threaded outer surface. The rod is extendably positioned through the first portion and is threadably couplable to the first portion. Rotating the rod in a first direction urges the first portion toward the second portion such that the first and second portions define an expansion bolt. The rod has a length greater than the bar.
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. Pat. 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 frost proof sill cock extraction tool apparatus and method which has many of the advantages of the sill cock removal devices mentioned heretofore and many novel features that result in a new frost proof sill cock extraction tool which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art sill cock removal devices, either alone or in any combination thereof.
It is another object of the present invention to provide a new frost proof sill cock extraction tool which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new frost proof sill cock extraction tool which is of a durable and reliable construction.
An even further object of the present invention is to provide a new frost proof sill cock extraction tool 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 frost proof sill cock extraction tool economically available to the buying public.
Still yet another object of the present invention is to provide a new frost proof sill cock extraction tool 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 frost proof sill cock extraction tool for removing a broken sill cock.
Yet another object of the present invention is to provide a new frost proof sill cock e
