ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to water heated tank apparatus and more particularly pertains to a new heater trough apparatus for heating water used for cleaning.
2. Description of the Prior Art
The use of water heated tank apparatus is known in the prior art. More specifically, water heated tank apparatus 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. 3,916,923; U.S. Pat. No. 5,325,548; U.S. Pat. No. 3,618,621; U.S. Pat. No. 2,915,072; U.S. Pat. No. 3,589,378; and U.S. Pat. No. Des. 364,253.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new heater trough apparatus. The inventive device includes a tank mounted upon a plurality of leg members each having an adjustable feet member threaded through a bottom thereof, the tank having side walls, end walls, an upper floor, a lower floor, a main compartment and a secondary compartment each having a hole extending through the upper floor; and also includes an exhaust member having an exhaust port and an exhaust vent disposed between the upper and lower floors; and further includes a pipe member disposed between the floors and having one end connected to the hole in the main compartment and having another end connected to the hole in the secondary compartment; and also includes a housing which protects a thermostat, a pipe, a gas shut-off valve and a safety shut-off valve disposed in the pipe, a venturi pilot member at one of the ends of the pipe which is connected to a heat-producing burner which is disposed below the pipe member, and a switch for energizing the heat-producing burner; and further includes splash guards disposed below the housing and the tank; and also includes a mesh screen mounted about the tank for the protection thereof; and also includes a drain pipe for draining heated water from the main compartment.
In these respects, the heater trough apparatus 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 heating water used for cleaning.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of water heated tank apparatus now present in the prior art, the present invention provides a new heater trough apparatus construction wherein the same can be utilized for heating water used for cleaning.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new heater trough apparatus apparatus and method which has many of the advantages of the water heated tank apparatus mentioned heretofore and many novel features that result in a new heater trough apparatus which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art water heated tank apparatus, either alone or in any combination thereof.
To attain this, the present invention generally comprises a tank mounted upon a plurality of leg members each having an adjustable feet member threaded through a bottom thereof, the tank having side walls, end walls, an upper floor, a lower floor, a main compartment and a secondary compartment each having a hole extending through the upper floor; and also includes an exhaust member having an exhaust port and an exhaust vent disposed between the upper and lower floors; and further includes a pipe member disposed between the floors and having one end connected to the hole in the main compartment and having another end connected to the hole in the secondary compartment; and also includes a housing which protects a thermostat, a pipe, a gas shut-off valve and a safety shut-off valve disposed in the pipe, a venturi pilot member at one of the ends of the pipe which is connected to a heat-producing burner which is disposed below the pipe member, and a switch for energizing the heat-producing burner; and further includes splash guards disposed below the housing and the tank; and also includes a mesh screen mounted about the tank for the protection thereof; and also includes a drain pipe for draining heated water from the main compartment.
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 heater trough apparatus apparatus and method which has many of the advantages of the water heated tank apparatus mentioned heretofore and many novel features that result in a new heater trough apparatus which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art water heated tank apparatus, either alone or in any combination thereof.
It is another object of the present invention to provide a new heater trough apparatus which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new heater trough apparatus which is of a durable and reliable construction.
An even further object of the present invention is to provide a new heater trough apparatus 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 heater trough apparatus economically available to the buying public.
Still yet another object of the present invention is to provide a new heater trough apparatus 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 heater trough apparatus for heating water used for cleaning.
Yet another object of the present invention is to provide a new heater trough apparatus which includes a tank mounted upo
