Application filed May 25, 1203. Seal 55,158,688. (No model.)
To @ZZ whom, it may concern:
Beit known that I, OLIVER H. ERNST, a citizen of the United States, residing at Crestline, in the county of Crawford and State of Ohio, have invented new and useful Improvements in Gas-Stoves, of which the following is a specification.
This invention relates to gas-stoves, and has for its object to provide a heaterof this type of a simple and practical construction, while at the same time comprising means for increasing the heating and radiating surfaces to the maximum.
Tothis end the invention contemplates a gas-stove structure of a convertible type whereby the same may be utilized either as a grate-stove for ordinary fuel or in connection with gas-burners and yet being so constructed as to utilize the heat to the greatest possible advantage, but permitting of the escape of the products of combustion'from the escapep1pe.
A further object of the invention is to so construct the stove as to be of special utility as a gas-heater employing natural or artificial gas for heating purposes and providing for circulating a body of air throughout the entire length of the stove-body and subjecting it during Ysuch circulation to the heated products without contamination with the latter, thus insuring a Vmaximum heating edect and providing for the discharge of pure heated air into the room to be heated. y With these and many'other objects in view,
which will more readily appear as the natureA of the invention is better understood, the
same consists in the novel construction, com-l bination, and arrangement of parts, which will hereinafter be more fully described, illustrated, and claimed. o" v I The essential feature of the invention involved in the novel manner of associating the hot-air chamber or pipe with the deflectingdiaphragms is necessarily susceptible to structural modification without departing from the scope of the invention; but a preferred embodiment of the latter is shown in the accompanying drawings, in which-'- Figure l is a vertical centrallongitudinal sectional view of a gasstoveembodyingthe present invention.
ward through a central hot-air Fig. 2 is a cross-sectional View on the line 2 2 of Fig. l. Fig. 3 is a similar view on the line 3 Bof Fig. l.
Like reference-numerals designate corresponding parts throughout the several iigures of the drawings.
In carrying out the invention the operative parts of the heaterare inclosed within an upright exterior stove-casing, (designated in the drawings by the numeral 1 and of Vthe usual sheet-metal formation.) The said exterior stove-casing l may be of a cylindrical, elliptical, or other suitable configuration in cross- -section, as it is only necessaryto employ a tubular casing l open throughout from top to bottom to properly accommodate the other elements of the stove.
The exterior casing l issuitably mounted at the lower end thereof upon anopen or hollow base-section 2, surmounted upon the supporting-legs 3, which serve to hold the bottom of the stove above the level of the floor to permit of the ready ingress of the air to be heated. Immediately above the plane of the open or hollow base-section 2 the exterior stove-casing l is of an expanded form to provide a lire-pot chamber 4,'which`acco1nmodates the wire. ln order to make the stove of a convertiblel type, the fire-pot chamber 4 is provided within the bottom portion thereof with any suitable type of fuel-grate 5, whereby ordinary fuel may be employed in the stove, and below the. plane of said grate is formed'with a pendent box extension 6, constituting a burner-pit which accommodates o ne or a plurality of gas-burners 7, designed to burn artificial or natural gas, the flame from which projects into the re-pot chamber 4, so that the heat therefrom will serve to heat up the air drawn into and circulated upchamber 8. When the grate of Vthe stove is utilized for ordinary fuel, it will be understood that the pendent box 6 also constitutes an ash-receptacle and that the same is removable by-bolts 6a. Also there are arranged at the sides of said receptacle perforations 6b for the admission of air.
The centralhot-air chamber S is in the form of a cylindricalor elliptical pipe extending longitudinally throughout the entire length of the stove-casing and having its lower open portion a pendent defiecting-dome 13 inlet end 9 projecting-through the burner-pit G and exposed within the open or hollow basesection 2, so as to be free to receive the supply of air which is to be heated up and circulated out into the room. rlhe upper open discharge end 10 of the hot-air chamber or pipe S is fitted to and opens through an imperforate closure-head 11, arranged horizontally Within the upper end portion of the stove-casing 1 and constituting a closing-diaphragm for that end of the casing, so as to completely confine the products of combustion within the body portion of the casing about the hot-air chamber or pipe 8V. The said upper end of` the exterior stove-casing 1 is also surmounted b y an ornamental grille or perforate distributingtop 12, through the openings or interstices of which the heated air discharged from the hotair chamber passes inthe room to be heated. To insure a proper deflection of the .heated products, so that the same may be uniformly passed through the grille top 12, the latter has fitted centrally to the under side of its top of a semispherical form and lying centered above the upper discharge end 10 of the hot-air chamber or pipe.
One of the distinctive features of the present invention resides in means for so retarding the passage of the heated prod ucts through the heating-space 14 between the stove-casing and the interior hot-air chamber as to secure a thorough and maximum heating eifect upon the chamber or pipe 8. lThis is prefer ably accomplished by the employment of a plurality of detlecting-diaphragms 15, arranged in the said heating-space 14 at intervals between the fire-pot chamber 4 and the imperforate closure-head 11 of the stove-casingf- Any desired number of the detlectingdiaphragms 15 may be employed; but the alternating order thereof always remains the same to provide for compelling the heated products to pass in a zigzag direction from one side of the casing to the other in its upward circulation toward the escape-opening 16, formed in the `casing side at or contiguous to the top thereof, said escape-opening 16 ijaving a suitable pipe connection 17 therewit Y Each of the delecting-diaphragrns 15 corresponds in general form to the cross-sectional contour of the stove-casing 1 and suitably fitted at its edges thereto, so as to prevent the leakage of the heated products eX- cept at the point provided therefor. Also each of said deflecting diaphragms 15 is formed with a horizontal section 1S, joined tightly to the casing 1, and also provided with a pipe-opening 19, receiving the hot-air chamber or pipe 8, and the edges of which opening tightly fit the said chamber or pipe and rest upon an annular supporting ring or collar 20, fitted to and encircling the chamber or pipe 8. At one side of the plane of the vertical air chamber or pipe 8 each diaphragm 15 has extended from its horizontal section 18 a downwardly-curved baffle-apron 2l, having a anged end portion 22, terminating short of ther adjacent side'of the casing 1 to provide an interval 23, constituting a circulatingpassage for the heated products. By reason of the diaphragme 15 being arranged with their baiiie-aprons 21 disposed alternately at opposite sides ot' the stove-casing the circulating-passages 23 aro necessarily disposed in alternate order at opposite sides of the casing, thus compelling the circulation referred to.
An additional baffling or retardation of the heated products is accomplished through the medium of an auxiliary upright baiiie-Wall 24, fitted to the horizontal section of the uppermost diaphragm 15 adjacent to the escape-opening 16.
While a single hot-airv chamber or pipe 8 has been described and illustrated, still it will be understood that a plurality of such cham- Y bers or pipes could be employed without affecting the invention.
Changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit of the invention or sacrificing any of the advantages thereof.
Having thus described the invention, what is claimed, and desired to be secured by Leto Y 1. In a stove of the class described, an upright casing provided at its upper end with an imperforate head and an open distributing-top, a hot-air chamber or pipe extending longitudinally within the casing and opening through the imperforate head thereof into the open top, and detiectors arranged in the heating space between the casing and the air chamber or pipe and having baffle-aprons terminating short of the adjacent side of the casing.
