Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a non-abrading gasket assembly and more particularly pertains to providing an assembly between rough parts of a gas infra red burner with a non-abrading gasket assembly.

2. Description of the Prior Art

The use of infra red burners is known in the prior art. More specifically, infra red burners heretofore devised and utilized for the purpose of radiantly heating 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.

By way of example, U.S. Pat. No. 5,110,287 to Macpherson et al. discloses an infra-red burner system for furnaces.

U.S. Pat. No. 5,306,140 to Smith discloses an infra-red generation.

U.S. Pat. No. 3,790,333 to padovani et al. discloses an infra-red burner.

U.S. Pat. No. 4,272,238 to Smith discloses an infra-red heating and burners.

U.S. Pat. No. 4,435,155 to Vigneau discloses an infra-red radiant burner.

While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a non-abrading gasket assembly for providing an assembly between rough parts of a gas infra red burner.

In this respect, the non-abrading gasket assembly 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 providing an assembly between rough parts of a gas infra red burner.

Therefore, it can be appreciated that there exists a continuing need for new and improved non-abrading gasket assembly which can be used for providing an assembly between rough parts of a gas infra red burner. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In the view of the foregoing disadvantages inherent in the known types of infra red burners now present in the prior art, the present invention provides an improved non-abrading gasket assembly. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved non-abrading gasket assembly and method which has all the advantages of the prior art and none of the disadvantages.

To attain this, the present invention essentially comprises an upper ceramic fiber gasket having a generally rectangular configuration. The upper ceramic gasket has two long edges and two short edges together joined end to end thereby forming the upper ceramic gasket. The upper ceramic gasket has a hollow opening within the joined two long edges and short edges thereof. The device contains a lower ceramic fiber gasket having a generally rectangular configuration. The lower ceramic gasket has two long edges and two short edges together joined end to end thereby forming the lower ceramic gasket. The lower ceramic gasket has a hollow opening within the joined two long edges and short edges thereof. The lower ceramic fiber gasket and the upper ceramic fiber gasket have identical dimensions. The device contains an interior steel gasket having a generally rectangular configuration. The steel gasket has a plurality of apertures formed therethrough inwardly around a peripheral edge thereof. The steel gasket has a downwardly extending spacer formed through a central portion thereof. The interior steel gasket is dimensioned to be coupled between the upper ceramic fiber gasket and the lower ceramic fiber gasket.

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.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular, to FIG. 1 thereof, the preferred embodiment of the new and improved non-abrading gasket assembly embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described.

Specifically, it will be noted in the various Figures that the device relates to a new and improved non-abrading gasket assembly for providing an assembly between rough parts of a gas infra red burner. In its broadest context, the device consists of an upper ceramic fiber gasket, a lower ceramic fiber gasket, and an interior steel gasket. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

The first component of the device 10 is an upper ceramic fiber gasket 12. The upper ceramic fiber gasket 12 has a generally rectangular configuration. The upper ceramic gasket 12 has two long edges 14 and two short edges 16 together joined end to end thereby forming the upper ceramic gasket 12. The upper ceramic gasket 12 has a hollow opening 18 within the joined two long edges 14 and short edges 16 thereof. The upper ceramic fiber gasket 12 is not limited in size, shape, or composition so as not to limit the effectiveness of the device 10. Ceramic is the preferred composition because of its ability to expand under intense heat. Other materials which expand under such intense heat may also be utilized.

The second component of the device 10 is a lower ceramic fiber gasket 22. The lower ceramic fiber gasket 22 has a generally rectangular configuration. The lower ceramic gasket 22 has two long edges 24 and two short edges 26 together joined end to end thereby forming the lower ceramic gasket 22. The lower ceramic gasket 22 has a hollow opening 28 within the joined two long edges 24 and short edges 26 thereof. The lower ceramic fiber gasket 22 and the upper ceramic fiber gasket 12 have identical dimensions. As with the upper ceramic fiber gasket 12, the lower ceramic fiber gasket 22 is not limited in size, shape, or composition so as not to limit the effectiveness of the device 10. Ceramic is the preferred composition because of its ability to expand under intense heat. Other materials which expand under such intense heat may also be utilized.

The final component of the device 10 is an interior steel gasket 32. The interior steel gasket 32 has a generally rectangular configuration. The steel gasket 32 has a plurality of apertures 34 formed therethrough inwardly around a peripheral edge 36 thereof. The steel gasket 32 has an aperture 38 centrally located therein which is defined by downwardly curved edge portions of the steel gasket. The interior steel gasket 32 is dimensioned to be coupled between the upper ceramic fiber gasket 12 and the lower ceramic fiber gasket 22. The interior steel gasket 32 and the upper and lower ceramic fiber gaskets 12, 22 have different rates of expansion. As a burner heats and cools, a scuffing action occurs at their juncture. As a result gasket life is short. Smooth surfaces of the interior steel gasket 32 provides a non-abrasive surface for the upper and lower ceramic fiber gaskets 12, 22 to slide on as they expand at different rates.

Utilization of the above mentioned components involves the use of other components as well. Such a component is a steel casting 42. The steel casting 42 has a lower edge 44. The lower edge 44 is dimensioned to receive the upper ceramic fiber gasket 12 therein. Also included is a permeable ceramic block 48. The ceramic block 48 has an upper surface 50 and a lower surface 52. The upper surface 50 receives the lower ceramic fiber gasket 22 thereon. The steel casting 42 and the permeable ceramic block 48 form a means for allowing flow of gas air mixtures through the aforementioned components.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
