WALTER CQLINDEMANN, OF MILWAUKEE, WISCONSIN, .ASSTGNOR TO A. J. LINDE- MAN N & HOVERSON COMPANY, OF-MILVI'AUKEE, WISCONSIN.
OIL srovn.
Application filed February 21, 1920. Serial No. 360,457.
T all whom it may concern:
Be it known that I, WALTER C. LINDE- MANN, a citizen of the United States, and a resident of the city of Milwaukee, in the county of Milwaukee, State of Wisconsin, have invented certain new and useful Improvements in Oil Stoves, of which the following is a specification.
The improvements relate particularly to burners of oil stoves, adapted to produce what is known as a white as distinguished from a-blue flame, and-have to do with the construction and arrangement of the burner parts, for the purpose of providing a'wick stop and securing other advantages.
In burners of this character the flame at the upper edge of the annular wick is supplied with oxygen to support combustion on both sides, the inside air supply usually passin up from the bottom of the stove through the inner tube or cylinder surrounding the wick, and the outside air sup ply being taken in at a point below the upper part of the outer wick tube and conducted to the upper edge thereof. To supply air in the proper manner and at the proper point and in just the right volume to support combustion is one of the great problems in all burners of this character, and the introduction of any new feature in burner construction which may aifect the conformation of hydrocarbon vapor, or the'conversion of that vapor first into carbon monoxide, or CO, and the conversion of this gas into carbon dioxide or CO without producing imperfect combustion or otherundesirable results is an extremely delicate task.
It has long been recognized that a wick stop which will prevent the user from turning the wick too high is a very important feature in burners of this character, and
various devices of this kind have been produced. These may be divided into two classes, viz: (1) wick stops connected with the wick raising and lowering means, and (2) wick stops acting on the wick direct. Among the objections to the first class is the one that they must be adjusted to the wick in its original condition and readjusted from time to time as the wick burns down, which is attended with difiiculties and uncertainties, and among the objections to the second class is the one that the production and combustion of the vapor is interfered with at certain times and under certain conditions due to their complex or cumbersome construction, or to other causes. Both forms of stops also give riseto trouble and inconvenience when it is desired to renew the wick: The primary objectof the present iniprovements is to provide ,a wick stop which will overcome these and other objectionsl' i I The improvements are illustrated in the accompanying drawing, in whichFigure 1 1s medial vertical section of a stove burn er' embodying the improvements, with the wick at its highest point; Figure 2 is a fragn' 'entary vertical section of the wick stop and adjacent parts with the wick'belowits highest point, and Figure 3 is a detail of the outer wick tube and stop. i H i "The inner wick tube A is a cylinder of sheet metal suitably supported and posi tioned, and adapted topermit the passage of air therethrough to the inner upper edge of the wick B in the annular space between the said tube A and the outer wick tube C, which is also properly supported and positioned. The wick may be raised and lowered by any sultable means, as, for instance,'the spur wheel D. Y 4
Supported on an open-work shelf E in the wick tube A is a deflector member consisting ot'the tubular part Fand the disk. G at its top, with edges overhanging the wick tubes and wick. The tubular portion F forms withthe inner wick tube A an annular space through which air passes upwardly to the upper, edge ofthe wick, and the disk servesto divert the air and the flame supported thereby laterally so as to produce al spreading flame.
Mounted on the exterior of, the outer j wick tube C and spaced therefrom by means of the flanges H is an outer deflector and shieldH', forming with said outer tube an annularspace for the'passa'ge of air, open at the bottom and top. The upper edges H of the said shield and deflector are turned inwardly so as to direct the air space substantially equal in area to the area of the wick space. The result of this construction is that when the wick is turned up: to the desired point, so as to give the maximum flame the wick comes in contact with the flange C and is prevented from rising further, while at the same time a suflicient area of wick is exposed to the heat of the parts and the combustion to give the desired vaporization for the support of combustion, and when the wick is turned down this exposed area is decreased thereby decreasing the vaporization of the liquid hydrocarbon in the wick and correspondingly lowering the flame. At the same time the air passing up through the inner wick tube mixes with the vapor issuing from the wick, causes the formation of CO and then CO and is diverted laterally as it rises,
, by the deflector disk G, to form a spreading annular flame. As the mixed air and vapor in a state of. combustion rises above the overhanging flange C it receives an additional supply of air from the annular space between the outer wick tube and the shield H, and in this manner substantially perfect combustion is produced. time the top of the wick is shielded, to a certain extent, by the flange G so that the vaporization is not excessive, and when the wick is turned down below the upper edge of the inner tube A the vaporization in the wick is not continued to a suflicient extent by the radiated heat of the parts thereabove to prevent the flame from being extinguished.
In the form of embodiment herein illustrated, theouter wick tube is extended above the inner tube and the stop is formed by an annular imperforate flange extending over the top ofthe wick. This construction has been found to give highly satisfactory results, but it must not be understood that the invention is limited to this construction,
since it is apparent that modifications of ported on the outer side of the wick and a suflicient exposure of wick surface provided in proportion to the air supply and in proper relation thereto, to give the desired results herein set forth.
At the same What I claim is:
1. In a burner the combination of an inner cylindrical wick tube, adapted to be surrounded by a wick, an outer wick tube concentric therewith and a font upon which the latter is mounted, said outer wick tube having an upper portion extending above the inner wick tube and turned inwardly over the space between the two tubes to form a wick stop, and an outwardly turned lower portion fitting over a portion of the font, whereby a removable connection between said tubeand font is formed, the said outer wick tube and its said parts be ing integral and forming one piece or part of the burner, and a surrounding shield and air deflector removably mounted exterior to said outer wick tube, having mem bers extending inwardly to contact with the exterior of said tube and downwardly to contact with the said lower portionthereof, and maintaining the same in laterally .and vertically spaced relation thereto. 7
2. In a burner the combination of an inner cylindrical wick tube, adapted to be surrounded by a wick, an outer wick tube concentric therewith and a font upon which the latter is mounted, said outer wick tube having an upper portion extending above the inner wick tube and turned inwardly over the space between thetwo tubes to form a wick stop, and an outwardly turned lo-werportion fitting over a portion of the font, whereby a removable connection be; tween said tube and ,fontis formed, the said outer wick tube and its said parts being'integral and forming one piece .or part of the burner, and a surrounding shield and .air deflector removably mounted exterior to said outer wick tube, having members extending inwardly to contact with the exterior of said tube and downwardly to con tact with the sa d lower portion thereof, and maintaining the samein laterally and vertically spaced relation thereto, said portions of the shield and deflector being frictionallyv engaged with said outer wick tube and removable therefrom. a
