ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lawn mower reel assembly measuring system and more particularly pertains to determining the taper in a reel assembly of a lawn mower.
2. Description of the Prior Art
The use of flexible measuring tapes of known designs and configurations is known in the prior art. More specifically, flexible measuring tapes of known designs and configurations previously devised and utilized for the purpose of measuring objects with a flexible tape through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 3,849,886 to Weyrick et al discloses a tape measure. U.S. Pat. No. 4,214,369 to Wasik et al discloses a pasta measurer. U.S. Pat. No. 4,294,016 to Wilkerson discloses an automobile height gauge. U.S. Pat. No. 4,928,401 to Murray, Jr. discloses a shaft alignment system. Lastly, U.S. Pat. No. 5,452,523 to Jansen discloses banding material lengths.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe lawn mower reel assembly measuring system that allows determining the taper in a reel assembly of a lawn mower.
In this respect, the lawn mower reel assembly measuring system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of determining the taper in a reel assembly of a lawn mower.
Therefore, it can be appreciated that there exists a continuing need for a new and improved lawn mower reel assembly measuring system which can be used for determining the taper in a reel assembly of a lawn mower. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of flexible measuring tapes of known designs and configurations now present in the prior art, the present invention provides an improved lawn mower reel assembly measuring system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved lawn mower reel assembly measuring system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a lawn mower reel assembly measuring system for determining the taper in a reel assembly of a lawn mower. First provided is a flexible tape fabricated of an essentially inextensible material. The tape has a short leading edge and a short parallel trailing edge. The tape also has long parallel side edges between the short leading edge and the short trailing edge. The tape has a front face and a rear face. A circular magnet is next provided. The magnet, or hook, is secured to the tape adjacent to the leading edge and adapted to be releasably secured to one face of a blade of a reel type lawn mower whereby the remainder of the tape may be wrapped around the reel assembly for determining the approximate circumference and diameter of the reel assembly of a lawn mower. Indicia is provided on the front face. The indicia includes equally spaced major markings with about 3.1416 inches between the major markings. Equally spaced minor markings are provided at every tenth of an inch between the major markings. Miniature markings are provided every fortieth of an inch between the minor markings. A vernier scale extends laterally offset from one side edge of the tape adjacent to the leading edge with equally spaced primary vernier markings at about 0.000, 0.005, 0.010, 0.015, 0.020, and 0.025 of an inch. Four equally spaced supplemental vernier markings are provided between each primary vernier marking. The 0.000 marking is offset from the 4.29 location of the front face and the 0.025 marking is offset from the 4.89 marking of the front face. In this manner, the tape may be wrapped around the blades of a reel assembly of a reel type lawn mower to determine its diameter and through wrapping and measuring at different locations of the reel assembly, the taper of the blades may be determined to assist in proper grinding.
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, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
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 descriptions 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.
It is therefore an object of the present invention to provide a new and improved lawn mower reel assembly measuring system which has all of the advantages of the prior art flexible measuring tapes of known designs and configurations and none of the disadvantages.
It is another object of the present invention to provide a new and improved lawn mower reel assembly measuring system which may be easily and efficiently manufactured and marketed.
It is further object of the present invention to provide a new and improved lawn mower reel assembly measuring system which is of durable and reliable constructions.
An even further object of the present invention is to provide a new and improved lawn mower reel assembly measuring system 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 lawn mower reel assembly measuring system economically available to the buying public.
Even still another object of the present invention is to provide a lawn mower reel assembly measuring system for determining the taper in a reel assembly of a lawn mower.
Lastly, it is an object of the present invention to provide a measuring system comprising a flexible tape fabricated of an essentially inextensible material with a short leading edge and a short parallel trailing edge, long parallel side edges, a front face and a rear face. An attachment member is secured to the tape adjacent to the leading edge and adapted to be releasably secured to an object to be measured whereby the remainder of the tape may be wrapped around the object for determining an approximate diameter. Indicia on the front face includes equally spaced major markings, equally spaced minor markings at every tenth between the major markings, and miniature markings between the minor markings.
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 o
