ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a motion imparting system and more particularly pertains to converting rotary motion to linear motion.
2. Description of the Prior Art
The use of motors and motion imparting systems of known designs and configurations is known in the prior art. More specifically, motors and motion imparting systems of known designs and configurations previously devised and utilized for the purpose of converting one type of motion to another 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. 4,579,011 to Dobos disloses a propulsion apparatus and U.S. Pat. No. 5,969,442 to McKee et al. discloses a reaction propulsion motor and apparatus for using the same.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a motion imparting system that allows converting rotary motion to linear motion.
In this respect, the motion imparting 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 converting rotary motion to linear motion.
Therefore, it can be appreciated that there exists a continuing need for a new and improved motion imparting system which can be used for converting rotary motion to linear motion. 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 motors and motion imparting systems of known designs and configurations now present in the prior art, the present invention provides an improved motion imparting 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 motion imparting 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 motion imparting system for converting rotary motion to linear motion. First provided is a centrifuge. The centrifuge has an upper circular end wall. A circular central aperture is provided in the upper circular end wall. The centrifuge also has a lower imperforate circular end wall parallel with the upper circular end wall. The centrifuge also has an imperforate cylindrical sidewall between the upper end wall and lower end wall. The end walls and side wall form a cylindrical chamber within the centrifuge. A quantity of fluid is provided within the chamber and fills a portion of the chamber. The centrifuge further includes a motor. A drive shaft is next provided. The draft shaft couples the center of the lower end wall and the motor to impart a rotary motion about a rotational axis to the centrifuge in a plane extending through the chamber and the drive shaft and the central aperture. The fluid is movable to move toward the sidewall under the influence of centrifugal forces caused by the rotation of the motor and drive shaft and centrifuge with air in the remaining central extent of the chamber. Next provided is a spherical ball. An exterior end of the ball is positioned within the fluid during rotation of the centrifuge and an interior end is positioned exterior of the fluid in the air during rotation of the centrifuge. Next provided is a rod. The rod extends through the central aperture. The lower extent of the rod is within the centrifuge and the upper end is above the centrifuge. The axis of the rod is parallel with but laterally offset from the axis of the centrifuge. A driver is provided to rotate the rod at the same speed as the centrifuge. Lastly, a flexible connector is provided. The connector couples the ball and the rod. Guides are provided. The guides are coupled to the sidewall. In this manner when the rod and centrifuge are rotated simultaneously during operation and use, the ball will continuously move to varying depths within the water to continuously displace a weight of water equal to the buoyancy force of the ball so that when the ball is out of the water to a greater extent then greater forces will be transferred to the rod and when the ball is out of the water to a lesser extent then lesser forces will be transferred to the rod and, as a result, the rotational forces within the system will be converted to a linear force.
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 motion imparting system which has all of the advantages of the prior art motors and motion imparting systems of known designs and configurations and none of the disadvantages.
It is another object of the present invention to provide a new and improved motion imparting system which may be easily and efficiently manufactured and marketed.
It is further object of the present invention to provide a new and improved motion imparting system which is of durable and reliable constructions.
An even further object of the present invention is to provide a new and improved motion imparting 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 motion imparting system economically available to the buying public.
Even still another object of the present invention is to provide a motion imparting system for converting rotary motion to linear motion.
Lastly, it is an object of the present invention to provide a new and improved motion imparting system for converting rotary motion to linear motion comprises a centrifuge. The centrifuge has a chamber. A quantity of fluid fills a portion of the chamber. A motor imparts a rotary motion about a rotational axis to the centrifuge and moves the water outwardly under the influence of centrifugal forces. An object has its exterior end positioned within the fluid during rotation of the centrifuge and its interior end positioned exterior of the fluid in the air during rotation of the centrifuge. A rod has an axis parallel with but laterally offset from the axis of the centrifuge. A driver rotates the rod at the same speed as the centrifuge. A connector couples the object and the rod whereby when the rod and centrifuge are rotated simultaneously during operation and use, the rotational forces with
