xINDLING BUPuNER INSTALLATION.

The invention relates to an installation for gas kindling burners in solid-fuel fire boxes.

An object of the invention is to provide an installation of the character described in which the kindling burner is disposed entirely out of the combustion portion of the fire-box space whereby it may at all times be relatively cool and cannot be damaged by the combustion of solid fuel in the fire box.

Another object of the invention is to provide the necessary secondary air for a kindling burner for a fire-box from without the fire box.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in .the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawings and description may be adopted within the scope of the invention as set forth in the claims.

Referring to said drawings,

Figure 1 is a fragmentary sectional View through a stove structure embodying the invention.

Figure 2 is a fragmentary side section taken through the fire box of the stove.

Figure 3 is an enlarged sectional View taken at the line 8-3 in Figure 2.

Figure 4 is an enlarged sectional view taken at the line 4- 1 in Figure 1.

In its present embodiment, the installation of our invention is incorporated with a combination stove 6 having a cooking top 7 beneath a portion of which is defined a top-gasburner chamber 8 and beneathanother portion of which is defined a fire box 9 for solid fuel. The chamber 8 and fire box 9 are separated by a common wall 11, and the chamber 8 is defined above a bottom wall 12, while the cooking top portion above the fire-box is provided with an opening 14 in which a plate '16 is arranged to be removably, mounted in a usual manneru v I I Preferably, the chamber 8 is divided generallyhorizontally by a member 17 to define a combustion compartment 18 above the member and immediately below thercooking top, and a fresh air supply compartment 19 constituting the remainder of thesp'ace of the chamber. Each top burner 21 is disposed generally in the compartment 19 and opposite an opening '22 in the member 17'whereby air in passingfr'o'm the compartment 19 will be directed overthe burner to provide the necessary secondary air supply therefor, conduit member 23 being shown mounted at each opening for guiding the air over the burner thereat. The member 17, it will now be noted, depends from the cooking top portion above the chamber 8 and is provided with an imperforate and substantiallyvertical side wall 24 at the edge thereof opposite the partition wall 11, the wall 24 being spaced somewhat from the wallll whereby the relatively cool fresh air compartment 19 extends the full height of the chamber adjacent the wall 11.

Upper and lower kindler burners 2 6 and 27 respectively are provided for the fire box. Preferably,- and as shown, theupper burner 26 is disposed to extend horizontally above the plane of the horizontal wall 12 and with the manifold portion 28 thereof in the compartment 19. Extending horizontally toward and into the fire box from the burner 26 through a slot 29 in the wall'll is a tapered ribportion 31 of the burner, which portion is preferably of uniform section throughout its length and extends horizontally substantially the full length of the fire box. The forward face 32 of the burner portion 29, it is noted, is formed to provide aseries of rectangular nozzles 83 having jet openings 3 1 connecting with the manifold passage 36, of the burner. The burner 26, it will be noted, is particularly intended to be used 0 both for igniting any solid fuel in the tire box and heating the overlying cooking top portion 16, and the jets of gas from the burner are directed generally horizontally for these purposes; whereby, when there is no solid fuel in the path of the jets, a horizontal sheet of fire may be provided beneath the cooking top.

The manifold portion of the lower burner 27 is also disposed without the fire-box space and at a level just above that of the fire-box grate 37 whereby gaseous fuel from the burner may be delivered directly into any solid fuelat the bottom of the fuel receiving space of the fire-box. This burner, it is noted, is formed generally as is the burner 26, and is here shown disposed generally inwardly of the latter burner with respect to the'fire-box, a lower portion 38 of the wall being appropriately offset and provided with .a slot 39 for the reception of the jet rib of the burner 27. I

As is usual, fire resistant linings are provided'for the sides of the fire-box, such linings including a lining member 41 for disposition posite the wall 11. The member 41, it will e noted, is'disposed generally inwardly of both of the burners 26 and 27 and extends substantially the full length of the fire-box and between the grate and cooking top. Toprovide for the projection of the flame jets from the burner26 through the member'41, the latter is provided with a series of generally rectangular openings 42 opposite the burner nozzles 33 andin spaced relation therefrom. Preferably, and as shown, an outwardly extending I flange 43 tapered in the manner of a nozzle is provided about the edge of each opening 42, whereby the openings provided in the liningmember 41' are protected somewhat, particularly from above, from the entry of ashes or other solid materials therethrough, these openings also providing, in effect, conduits about the bases of the flame jets from the burner nozzles. As here shown, the member 41 is secured to the wall ll'by bolts 44, spaced projections 45 and 46being provided on the member 41 for maintaining the proper spaced relation of the member and wall. As herewith particularly shown, the projection 45 is formed as a continuous rib overlying the slot 29 of the wall and extending the full length of the lining member whereby the space between the member and wall and above the burners is partitioned off.

It will now be noted that the relation of the burner nozzles 31 to the tapered openings 42 is such that as the gaseous fuel is discharged through the openings, air will be drawn from behind the lining member 41 and into the flame jets whereby it may serve as a secondary air supply for the jet. Such a supply is, of course, necessary for effect- .ing a complete combustion of the fuel from the nozzles 31, and the relation between the nozzles 31 and member 41 is preferably such that substantially all of the necessary air for the purpose is provided through the openings 42. In this manner, combustion of the discharged fuel is insured regardless of the contents of the combustion space of the fire box, and no smothering of the flames of the jets is possible as might occur when solid fuel is being simultaneously consumed in the fire-box.

With the present structure, air must of course be admitted to the space 47 defined between the member 41 and wall 11, and below the rib 45, and while the opening at the bottom of the member .41 might serve for the purpose, the draft created across the nozzles of the burner 27 would tend to interfere with proper combustion of fuel at such burner. Accordingly, the wall 11 is preferably provided with a longitudinally extending openv ing 48 adjacent the burner 26 whereby air for by bending out of the plane of the wall a rectangular port-ion 49 thereof, such portion being left attached to the wall along one longitudinal edge and constituting a louverin effect. In this manner, a sufficient secondary air supply is insured for the burner 26 and the effective passage provided at the opening 48 may be adjusted in a simple manner by adjusting the angular relation of the louver 49 to the wall 11.

Preferably, and as shown, the various 0pposed portions of the member 41 and wall 11 are substantially equally spaced throughout the entire height of the former whereby any solid material which may enter the space 47 cannoteasily wedge or become lodged in such space.
