4 This invention relates to gas ranges and more particularly to gas burners and supports therefor.
The principal object of the present invention a is the provision of a gas burner having an enlarged substantially flat top area for directly supporting and communicating a uniform and increased heat to the cooking vessel.
Another object is to provide a gas burner having a' relatively large flat top cap wherein means is provided for stabilizing and holding down the burner flame so that the heating capacity of the burner is increased and also permitting a low turn down of the flame.
Another object is the provision of a spill over cup adapted to carry and support the burner on the stove cooking topwhereby the vessel support- I ing grid of the cup and the flat top of the burner are in substantially the same plane thus congo stituting'a relatively flat vessel supporting surface.
A further object is to provide a gas burner having a. relatively largeflat top so that heat stored therein will continue to heat the cooking 55 vessel supported thereon after the gas has been turned off. 7
Still another object of the invention is to provide a construction of burner whereby the usual grid may be dispensed with and consequent elimination of all trouble and expense due to impingement of flame on such grid. I
A further object is to provide a gas burner wherein annular relatively flat flanged cap means is provided for directing the heat downwardly to prevent the ports from becoming clogged in the case of a spill over.
An additional object is the provision of a burner having a relatively flat cap portion for supporting a cooking vessel thereon thus overcoming the necessity of providing separate grids or supporting members which members obstruct the flame and reduce the efliciency of the burner.
Other objects and advantages will be apparent as the following specification is considered in' connection with the accompanying drawings, wherein:
Figure 1 is a plan view of the spill over supporting cup, spill over plate and burner casing in assembled position;
Figure 2 is a vertical cross section of the assembled device along the lines 2-2 of Figure 1;
Figure 3 is a vertical cross section of the assembled device along the lines 3-3 of Figure 1;
Figure 4 is a plan view of the burner casing with the spill-over plate removed; and
Figure 5 is a top plan view of the spill-over plate.
Referring more particularly to the drawings wherein similar reference characters designate like parts throughout the several views, numeral l designates a portion of the cooking top of a range, having an opening 2 therein for the reception of an annular metal concave cup or bowl 3. This bowl has integral utensil supporting grids or grid portions 4 formed on the upper peripheral rim 5, the latter seating in suitable depressions or recesses 6 in the edge of the stove top opening for supporting the cup in position within the opening. An annular tubular burner casing I, provided with a central opening 8, is cored out to form a fuel chamber 9 to which fuel is fed by fuel pipe l leading from a source of fuel supply, not shown. The central opening 8 is enlarged at its upper end, as at H, and a row of upwardly and inwardly inclined inner ports l2 are formed in the inner burner wall to discharge the gas into this enlarged opening or chamber .l l. A row ofouter ports or gas orifices l3 are also formed in the outer wall thereof. The usual ignition port It is formed in outer wall of the burner casing.-
A central opening or air passage l formed in a tubular annular base plate It, secured to the burner casing I by suitable bolts or the like l1, communicates with the opening 8 of the burner casing. Lugs I 8 on the casing 7 seat in recesses 20 on the edge of a central opening l9 in the cup 3 and thereby maintain the burner casing in position on the cup.
A spill-over plate 2 I, having a substantially flat, utensil supporting face 22, level with or in the same plane as the grids 5, and a central opening 22 of less diameterthan that of the opening 8, is secured to the relatively flat top face 23 of the burner casing by screws or the like 24. Flash tube channels 25, one or more of which may be employed, are formed in the top face 23 of the casing to conduct the flame from a set of lighted ports to a set of unllghted ports. For example, if the inner burner ports l2 should become extinguished or fail to light, they would be lighted by flame passing from the outer lighted burner ports l3 through one or more flash tube channels 25 to the inner ports. The spill-over plate 2| has 'a depending annular flange 28 which overhangs the burner and terminates a short distance above the outer row of burner ports l3 and thereby acts as a spill-over flange for the casing, to prevent liquids and the like from entering the outer ports, -As the lower edge of the annular flange is spaced from and terminates above the outer row of ports, the flame emanating therefrom will be directed thereagainst and caused to be uniformly distributed around the side face of the flange, which permits the ports to remain lit when the fuel supply is turned down verylow. This flange also reduces the velocity of gas flow and therefore increases the flame propagation. This annular flange 26 is also formed with channels 21 leading to theflash tube channels 25 to facilitate the lighting operation, previously described.
Two or more relatively shallow channels or grooves 28, formed in the flat utensil supporting face 22 of the spill over plate, serve as flues and thereby enable the products of combustion to circulate over the entire area of the supporting face when a cooking utensil is placed thereon.
As the construction just described permits of the cooking utensil being directly supported on the flat top face of the burner spill over plate, and on the grids 5 it will be understood that the heat from the burner is conducted directly 7 to the cooking vessel, it being unnecessary to provide separate supporting grids which would obstruct ahd cause the heat from the burner to be dissipated. In other words, the absence of supporting grids or ribs brings the cooking vessel closer to the burner outlet ports and thereby greatly increases the heating capacity and emciency of the burner. In addition to supporting the burner casing, the concave cup 3 acts as a spill over basin to catch the drippings from the cooking vessel or spill over plate, and the curved face 3' thereof also increases the efliciency of the burner by reflecting the heat from the burner upwardly and inwardly against the vessel.
The enlarged flat area of the burner spill over plate permits of a large quantity of heat being stored in the space between the plate and the top of the burner casing, which heat is communicated directly to the cooking vessel and permits of the latter being kept hot for a considerable length of time after the gas in the burner is turned off. Furthermore, the enlarged flat top face of the spill-over plate and the depending annular flange 28 thereon will become very hot from direct contact with the flame emanating from the burner outlet ports so that in the event of a spill over, the waste material will be evaporated before it reaches and clogs or blocks the ports.
While the spill over plate has been shown as being bolted to the burner casing, it is to be understood that the same may be merely supported thereon, or both the plate and easing may be cast as an integral unit; if so desired. In some cases it may also be desirable to support the burner casing on the burner tube rests or gas conducting pipes, rather than suspending and supporting the same on the spill over cup 3, in the manner shown herein.
It should also be noted from the foregoing that the cooking utensil is supported directly on the face 22'of the plate 2| and the top face of the integral grid members 5, formed on rim 4' of cup 3, thus eliminating the initial expense of conventional grids. Furthermore, the trouble incident to flame impingement on the conventional grid is obviated asthe integral grid portions 5 are so remote from the burner as to be entirely beyond the spread of the burner flame, and the burner seating recesses 20. being considerably below the burner ports l3 no flame impingement can occur at this point. The elimination of all obstruction to the flow of heat from the burners to the cooking utensil insures a substantially uni-- form distribution of heat which has proved impossible with the use of conventional grids.
The drawings and description have been directed to a preferred embodiment of the burner and supporting cup assembly but it is to be understood that various modifications and improvements may be made without departing from the scope and spirit of the appended claims.
Having thus described our invention, what we claim is:
1. In a gas burner, a hollow body portion having a fuel chamber and having ports communicating with said chamber on the inside and outside some distance below the upper end thereof, an annular substantially flat spill over plate secured on the upper end of the body portion and having small spaced channels between the bottom of the spill over plate and the top of the burner body and flash tube channels in the top of the casing communicating with said flrst mentioned channels and with said ports.
2. In a gas burner, a hollow body portion having a fuel chamber and having ports communicating with said chamber on the inside and outside some distance below the upper end thereof, an annular substantially flat spill-over plate secured on the upper end of the burner and extending beyond a vertical line with the inner and outer ports, an annular downwardly extending flange carried by the outer edge of the spill over plate and terminating at a point just above the outside ports and said spill-over plate having small spaced channels between the bottom thereof and the top of the burner and extending through said annular flange and flash tube channels formed in the top of the casing communicating with said first mentioned channels and with said inner and outer ports. I
3. In a gas stove having a cooking top provided with an opening, an annular concave supporting cup mounted in said opening, a hollow gas burner having a fuel chamber provided with inner and outer burner openings and mounted in the .lower end of the supporting cup and having passages between the same, an annular substantially flat top thereof and said plate, said plate having a central opening therein, and shallow grooves formed in said plate communicating with said central opening, an annular cup shaped member adapted to be removably mounted in a cooking top of a stove, and formed with aeentral opening through which said hollow body portionprojects.
