Application filed September 27, 1917. Serial No. 193,426.
To all whom it may concern:
Be it known that I, HENRY W. ODown, a citizen of the United States, residing at Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Gas Stoves, of which the following is a specification.
The invention relates to stoves and more particulary to gas stoves having grid tops.
Objects of the invention are to provide an improved form of construction of the character referred to which shall be simple, durable and economical in construction, and highly efficient in operation. These and other objects of the invention will in part be obvious and in part be more fully set forth in the following description.
The invention consists in the novel parts, improvements, combinations and features of construction herein shown and described.
In the drawings referred to herein and forming part hereof, are shown several embodiments of the invention, the same serving in connection with the description herein to explain the principles of the invention and set forth its chief advantages.
Of the drawings:
Fig. l is a top plan of a gas stove constructed in accordance with certain features of the invention;
Fig. 2 is a transverse section taken on the line 2-2 of Fig. l;
Fig. 3 is a top plan of a modification; and
Fig. at is a sectional View taken on the line a e of Fig.
A. gas stove constructed in accordance with one feature of the invention comprises a top having spaced-apart bars adapted to support a heating utensil and having ends arranged to form outlets for the products of combustion.
According to another feature of the invention, said bars are arranged in parallelism and are also arranged at their opposite ends to form outlets for the products of combustion.
According to yet another feature of the invention, a burner is arranged beneath the parallel bars, said burner having spacedapart jet members arranged in register with the spaces between said bars.
Referring now in detail to the drawings,
there is shown in Figs. 1 and 2 an embodiment of the invention comprising a frame consisting of oppositely arranged sides 6 and 7 and. a front 8 and back 9, a bar 11 being arranged in the preferred form of the construction, and preferably midway between said front and back of the frame, to lend rigidity to the structure, which is supported bylegs. 12 suitably disposed, as shown, at the corners of the stove.
According to one feature of the invention the stove is provided with a top which is so constructedthat the heated products of combustion are brought into and kept in contact with the heating utensil in such a way and for such a length of time as to impart their heat to the utensil to the best advantage and to the greatest extent. In the embodiment of this feature of the invention illustrated in the drawings, therefore, the top is provided between the front 8 and back 9 with a series of spaced-apart members or bars 18, preferably arranged longitudinally in parallelism, and supported at their opposite ends on the sides 6 and 7, as shown being cast integral with said sides. While the bars 13 may be of any desired length and extend over the stove to any desired extent, as shown, they do not extend beyond the sides 6 and 7. Also, the
top surfaces of the bars are preferably flush with each other and in the stove illustrated with the front and back.
It will be seen that when a heatin utensil is placed upon these bars 13 it Wlll, with the sides of said bars, form Hues extending the entire bottom of the utensil, and that the heated products of combustion, rising from burners suitably disposed beneath the bars and to which further reference will presently be made, will come in contact with more a very large heating utensil, as a wash boiler, can be accommodated by the stove, and it can be slid on and 01f with facility.
Accordingto another feature of the invention the stove top is so constructed that an outlet will be provided for the heated products of combustion, irrespective of the size or shape of the heating utensil. In the embodiment of the invention illustrated in the drawings, the bars 13 are formed integral with the side members 6 and 7 as stated, but the spaces between the bars 13 above the said sides 6 and 7 are left free. It will be seen. therefore, that no matter how large the utensil which may be placed upon the stove, the heated products of combustion afterv passing through the tines formed by the sides of the bars 13 and the bottom of the utensil will pass out to the atmosphere between the .free ends of the bars above the side members (3 and 7, it the-utensil is large enough to cover the stove to its extreme length, and in this way the draft is kept constant and combustion at the burner maintained.
Eluitable provision is made for supplying,
the heat to the stove. In the embodiment of the invention:illustrated in Fig. 1., two burners of the ordinary star shape are disposed at a suitable distance from each other and from the top oi the stove. The number of burners may be suited to the size or" the stove. It is an advantage of the invention, however, that even when several burners are provided, but one burner need be ignited to heat a very large heating; utensil, as the heated products of combustion passing through the fines between the bars 13 and the bottom of the utensil will impart their heat to the bottom of the utensil during the entire passage before passinginto theatmosphere. Ita small utensil is used, the
heated products of combustion will pass through the lines and escape npwardlybetween the bars 13 after passing the bottom of the heating utensil. The products oi? combustion will escape through the tines formed by tliebars 13 andthe bottom of the utensil in whichever direction said. bars 13 extend, said bars extending in the pa1.:ticular embodiment illustrated in the direction of'its length. The several burners may be connected, as shown, to a bar 19 which is fastened at its ends to the respective sides 6 and 7, this construction contributing .to the strength of the structure.
In accordance with another feature of the invention and as illustrated in the modification shown in Fig. 3, there is provided a type oi? burner 16 which is peculiarly adapted to act in combination with the parallel bars 13 heretofore described. This type of burner, of which two are shown in the particular embodiment of the'invention illustrated in said figure, consists of a plurality of gas tubes or jet members 17 which are disposed at a suitable distance beneath the stove top in register with the spaces between the bar-meinbers 1.3 of the top. It will be seen that the heated products rising from the combustion of the gas at the jets 18 in the respective jet members willproceed directly into the spaces between the bars 18 and that the streams of products will be aligned in the direction of the lengths of the respective flues. Gas is sup plied from any suitable source as by pipe 21, and the usual Bunsen burners 22 and valvesQS are supplied;
It will be seen that a stove constructed in accordance with the invention above described will carry out the objects of themvention as heretofore set forth,- besides possessingother advantages which will be apparent to those skilled in the art.
The invention in its broader aspects is not limited to the precise construction shown and described, nor to any particularconstruction by which it has been or maybe carried into effect, as many changes maybe made in the details thereolfwithout'departing from the main principles of the invention or sacrificing its chief advantagesj lVhat I claim is:
1. A stove including a frame comprising oppositely disposed side and end sections; a connecting bar between two of said sections; a burner comprising sections disposed on said bar; a top comprisinga series of spaced apart bars arranged in approximate parallelism longitudinally and supported at their opposite ends on certain of the sections; the top edges of the bars being" in the same plane and above the plane of the sections upon which they rest, to constitute, when covered by a' cooking utensil, channels to direct the heat currents and outlets for products of combustion between the bottom of the utensil and the sides of the frame; certain of the burner sections being arranged. approximately parallel with the spaces betweenthe bars, these parallel sections presenting longer heating surfaces towards the center of the bars.
2. In a gas stove, the coi'nbination of 'a frame-having end members extending from front to rear, a stove top supported bysaid frame, and a gas burner sustained beneath of the stove, and whereby the cooking utenended flues through which the heat currents sil may be shifted about on the upper flush Will flow towards and escape at the ends of 10 edges of the bars from one part of the top the stove and Will be prevented from disto the other Without obstruction, the said charging at the front of the same.
bars being individually of such height and In testimony whereof, 1' have aflixed my at such distance apart, that When covered signature hereto.
by a cooking utensil, the channels between the bars will constitute continuous open HENRY W. ODOWD.
