ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to chalk line compositions for chalk line devices and more particularly pertains to a new water proof chalk line compositions for use with chalk line devices for snapping guide lines on wet surfaces that will not wash away when precipitation such as rain falls thereon.
2. Description of the Prior Art
The use of chalk line compositions for chalk line devices is known in the prior art. More specifically, chalk line compositions for chalk line 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. 5,476,722 by Sakamoto et al.; U.S. Pat. No. 5,688,316 by Pettini et al.; U.S. Pat. No. 1,949,147 by Dove; U.S. Pat. No. 3,897,023 by Couch et al.; U.S. Pat. No. Des. 314,156 by Doyle; and U.S. Pat. No. 5,082,498 by Kurtz et al.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new water proof chalk line compositions for use with chalk line devices. The inventive device includes an effective amount of colored chalk mixed with an effective amount of concrete dye and applied to a moistened snap line of a chalk line device.
In these respects, the water proof chalk line compositions for use with chalk line devices 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 snapping guide lines on wet surfaces that will not wash away when precipitation such as rain falls thereon.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of chalk line compositions for chalk line devices now present in the prior art, the present invention provides a new water proof chalk line compositions for use with chalk line devices construction wherein the same can be utilized for snapping guide lines on wet surfaces that will not wash away when precipitation such as rain falls thereon.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new water proof chalk line compositions for use with chalk line devices apparatus and method which has many of the advantages of the chalk line compositions for chalk line devices mentioned heretofore and many novel features that result in a new water proof chalk line compositions for use with chalk line devices which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art chalk line compositions for chalk line devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises an effective amount of colored chalk mixed with an effective amount of concrete dye and applied to a moistened snap line of a chalk line device.
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 water proof chalk line compositions for use with chalk line devices apparatus and method which has many of the advantages of the chalk line compositions for chalk line devices mentioned heretofore and many novel features that result in a new water proof chalk line compositions for use with chalk line devices which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art chalk line compositions for chalk line devices, either alone or in any combination thereof.
It is another object of the present invention to provide a new water proof chalk line compositions for use with chalk line devices which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new water proof chalk line compositions for use with chalk line devices which is of a durable and reliable construction.
An even further object of the present invention is to provide a new water proof chalk line compositions for use with chalk line devices 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 water proof chalk line compositions for use with chalk line devices economically available to the buying public.
Still yet another object of the present invention is to provide a new water proof chalk line compositions for use with chalk line devices 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 water proof chalk line compositions for use with chalk line devices for snapping guide lines on wet surfaces that will not wash away when precipitation such as rain falls thereon.
Yet another object of the present invention is to provide a new water proof chalk line compositions for use with chalk line devices which includes an effective amount of colored chalk mixed with an effective amount of concrete dye and applied to a moistened snap line of a chalk line device.
Still yet another object of the present invention is to provide a new water proof chalk line compositions for use with chalk line devices that lets a construction crew work through wet weather when snapping guide lines with a chalk line device.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.
