GAS RANGE A I) BURNER THEREroR Application filed October 4, 1926. Serial No. 139,400.

This invention relates to improvements in gas ranges and burners therefor, the particular features being pointed out hereinafter.

One of the features of the present invention is substantially closing that part of the range containing the open burners, sufficient space being provided in its sides and bottom for the passage of air for the burners, the burner top being substantially closed with the exception of the grids for supporting the cooking utensils. Another feature of the invention is making a particular kind of burner which is small as compared with the grids for supporting the cooking utensils and at the saute time so constructing the burner that the flame spreads under the utensil, the topabove the burners being substantially closed but at the same time provided with openings sufficient to accommodate the flame from the burners. A further feature of the present invention is making a burner much smaller in circum ference than the grid on which the utensil is placed, causing the utensil to form a protection to the burner below from overflow of what may be cooking.

Another feature of the present improvement is providing burners formed very much above, and so constructing the burner that the flame is caused to spread over a surface as great and possibly greater than the surface of the grid portion. 7

A further feature'of the present improvement is to provide a central .manifold to which the four burners are connected, and from which the separate manifolds of the burners extend in opposite parallel direclocated at the usual four corners o the burner top.

Another feature of the present invention is providing supports for the free ends of the burner manifolds, or the bottom of the burners themselves, whereby the said burners are supported in proper position and are readily removed and replaced.

Another feature of the present invention smaller in circumference than the open grids tions, whereby the said burners are pro rly is combinin with the burners as above stated and said supports, certain members carried by the manifolds of the burners or the lower ends of the burners themselves whereby the burners cannot be placed in their 'wrong positions, thus insuring at all times that the parts are properly assembled.

Further features of the present invention will appear from the following descripton.

Referring now to the accompanying drawings in which: I 50 Figure '1 is a perspective 'view of a. stove I which embodies the present invention.

Figure 2 is a. top plan view of the stove.

Figure3 is a horizontal section through I Figure 1 just below the top portion.

Figure 4 is a vertical sectional view on the line 4-4 of Figure 3.

Figure 5 is a vertical sectional view on the line 5-5 of Figure 2.

Figure 6 is a view of the burner and its support, the same being shown in disconnected relation.

Figure 7 is an enlarged view partly in vertical'section through one of the burners and its manifold.

' Referring now to the drawings, -1 represents the "oven of the range 'to one side of which is supported the open burner construction that will be now "explained.

This open burner construction in carrying out the present improvement, consists of a rectangular arran ement comprising a front 2, an end 3, a baci 4 and an oven ortion 5, all of which are vertically dispose In addition to the above is the top, which in this instance preferably is com rised of two top members 6, which top mem ers are also substantially closed with the exception of the grid portions 8, and relatively smaller openings '9 located at the edge of said grids. The particular construction of this top will be described hereinafter.

In carrying out the above described closed construction and the necessary cooperating parts, attention is called to a centrally arranged as manifold 10, that is connected with a uel supply 11 that asses through the rear wall 12 to a source of supply which tions are at all times insured, the construc- .folds 13 have their lower shutter ends 14 extending 'down and loosely fitting around nozzles 15' that extend from the gas manifold 10, while projecting vertically from the upper ends of these manifolds are the burners 16 the whole structure provides a Z- shaped member.

By referring to Figure 2, the relative size of the burners 16 compared with the grids 8, is clearly shown. From this it will be readily realized how the burners are substantially completely protected from overflowing cooking by the utensil itself which is always substantlally as large as the grid 8.

The supply of gas from the central manifold 10 to the respective burners is controlled by suitable handles 17 that are connected by a suitable rod 18 with the valve control 19. The stove is preferably provided with a pilot 20 which is controlled by a handle 21 extending through the front 2 which will send out flames for lighting the respective burners. The type of pilot is well understood and need not be further described or illustrated.

We have heretofore referred to the fact that the burner manifolds and burners are detachable from the central manifold 10, gr which will now be specifically explained. In

placing these burners in position, the memer 21 which extends from the lower end of the burner 16, or may extend from the manifold itself, is passed through an opening 22, made in asupport 23 that extends across betweenthe walls 3 and 5 with its ends connected thereto. This support 23 has in addition to the-opening 22, a lateral opening 24 which is adapted to receive the pro ection 25 located on the lower side of the member 21, and the member 21 has a horizontally extending projection 25, the urpose of which will be presently explained? In assembling the burners the member 21 and projection 24 are passed through the openmgs 22 and 24, after which the shutter part4 is placed on its nipple and the angle of the manifold 13 is regulated by the projection 25 substantially engaging its support 23. In detaching the burners from the stove, the shutter end thereof is lifted when the member 21 can be readily with-.

drawn from its support. In this manner burners and manifold are readily,assembled and detached and their proper relative position being such that the parts cannot be assembled in their wrong relative positions.

I When they'are assembled, two of the mani folds and the burners extend in one direc-' tion and the other two in another direction, while they all extend in parallel horizontal planes as' well as vertical planes. This insures that the burners will occupy the usual corner positions of the top 6.

At this point we will refer to the particular construction of the burner 16. This burner is covered per se 1n an application filed b the present inventor on August 30, 1926, erial No. 132,534, but a burner constructed as disclosedin the application has a special function in connection with the top 6 as will now be explained. Hereinbefore it has been stated that these burners are ver much smaller than the gird 8 which is one eature of this special burner in connection with this top, it having the advantage hereinbefore referred to. This burner has its outer wall provided with openings 26 that extend outwardl with openings 27 that extend upwardly an inwardly at an angle. By reason of this construction a burner much smaller than the gird produces a flame that completely covers the bottom of the utensil above, the flame spreading and also being concentrated on the bottom of the utensil and insures that its contents will be heated substantially alike throughout its entire bottom, while at the same time the openings 9 around the grids 8 provide passages for this enlarged flame so that the flame will cover the complete bottom of the utensil that is larger in diameter than the diameter of the My new top 8 is made preferably in two like parts being divided at its center 28 for convenience in the handling of the same.

The construction of this has been described in respect to the grids and the openings in it, and in addition particular attention is called to the ribs 29 which are elevated and arranged so that the utensils may be readily moved around on the top, and at the same time so that they will be above the top. For instance when the utensil is over the grid, then there is a space between it and the top for the passage of the flame from the burner,

whereas the utensil can be readily moved laterally on the top to any desired position. There is preferably provided one 'or more solid grid portions which may be used if desired, and these are particularly adaptedvfor small articles. When a small utensil is being heated, for instance a cup of any kind, this solid part 30 will protect the burner belowfrom the overflow from the utensil and at the same time it will provide a solid heating surface. As to the ridges on this top 8, attention is directed to the fact that the said ridges that connect with the grid portions are made angular in formation, while the other ridges 31 extend'radially to the grids.

The bottom. of the rectangular portion comprising the walls 2, 3, 4 and 5 is pro- Vided with a dirt slide 32 which-is capable of being removed for the purpose of'cleaning it. This dirt slide will naturally receive part of the overflowing material, that part remaining on .the top also being readily removed. This dirt slide 32 substantially closes the bottom of the structure, there being left, however, room around it so that air will flow to the burners, as well as flow through the openings 33 in the walls 3 and 4. These openings together with the portions, serve to substantially enclose the burners and the main manifold whereby they are all out of sight, thus producing a very popular structure.

While I have described-in detail the'present invention, I wish it understood that variations may be made in the construction shown and described without departing from the scope and spirit of the present invention, so long as the said variations will come within a fair interpretation of the appended claims.
