This invention relates to stoves.

One of the principal objects of the invention is the provision of a stove having a removable interceptor piste positioned beneath the cooking surface oi the stove which is of simple construction, is readily removable, is effective as an interceptor, and for directing fuel lotv from the burners to provide for burner ignition from a pilot light.

Another object of the invention is the provision in a stove of a readily removable interceptor plate for the reflection of heat to the food containers on the cooking surface.

Another object of the invention is to provide an interceptor plate so positioned and in which the interceptor plate also carries passages forming parts of the stove lighter.

Other objects and advantages of the invention will he apparent from the following descriptions, the accompanying drawings and the appended claims.

In the drawings, which disclosea preferred embodiment-'oi the invention- Fig. 1 is a plan view' of a stove construction inv accordance with the present invention; certain of the parts being broken away for clearness of illustrations.

Fig. 2 is a sectional view taken on the line 2--2 oi Fig. 1.

Fig. 3 is a vertical sectional view taken on the line 3--3 of Fig. l. l Fig. 4 is a plan view of the ybottom side of the interceptor plate, and

Fig. 5 is a sectional view taken.- on the line -t of Fig. 4.

' The drawings, in which like characters of reference designate like parts throughout the several views thereof, illustrate a vcooking stove which comprises generallyl a stove supporting frame it upon which is mounted a cooking top frame member ii... The cooking top frame surrounds and forms an venclosure for aplurality of burners l2 and the food containing vessels rest upon the upper or cooking surface thereof. 45 Fuel is supplied to the various burners from 'a 'manifold it to which suitable valves l5 are attached; the valves having control handles i@ by which the flow of fuel to the burners. l2 may be regulated.y

In the'illustrated embodiment of the invention,

the cooking top frame llisformed of a single 1 piece of sheet metal, which is depressed at i8 adjacent the inner edge to form a seat for a closure 55 plate I9 which closes the entire cooking top si'. 3i, 193i, Seriai No. 560,328

frame opening and completes the cooking surface of the stove. The cooking top frame member continues downwardly and inwardly from the depression it to form a flange 2li which terminates in a down turned lip 2l.'

The ycover or closure plate i9 is shown as a singie integrally formed casting for the support oi cooking vessels and has openings 22, deiined by down turned annular flanges 23, which stand aligned with the burners i2 positioned therebeneath. Circular cover plates 2d are provided for the openings 22 and stand supported upon the flanges 23. The tops of the plates 2d arepreierably formed level with the surface of the closure plate l@ so that the entire stove .top presents a smooth unbroken 'surface over which cooking vessels may be readily moved. a

The soiid unbroken top provided by the cover it and plates iii serves to prevent free dissipation of heat from the burners l2. To restrain the heated air and products of combustion from the burners from passing down into the body of the stove a heat dee'cting or intercepting plate i@ -ispositioned within the opening denedby the cooking top frame lip 2l; this plate 26 being at substantially the level .of the upperl the burners l2.v Asshown, the plate 26 extends across substantially theentire opening as'delned by the lip 2l, and is cut away at the burners l2 as indicated at 2l. The plate openings 2l are preferably of smaller size than the openings in the cover plate interceptor plate. IIhe plate 25 as shown is formed as a single integrally formed casting, and is provided with upturned flanges 2li surrounding the several plate openings. As the openings 2l surfaces of f i9 which is positioned above theare of less size than the related closure plate openings, the 2t., which bind the plate openings 2l serve as a means for somewhat retaining on the any substance which may be spilled on the cover i9 and which then runs over the edge of a plate opening and down into the stove. Also, these upturned anges' Zmay, where they ,encircle the burners i2, serve as a guard to preventv cross currents from interfering with proper burner operation-this being particularly true with respect to products of combustion from the front burners. A normally burning pilot light til, which is conv nected to the'source ofv fuel supply, is provided for ignition of the burners l2. Means are associated with the deilector plate 2t to provide passages whereby unburnedy fuel issuing from a burner i2 may pass to the pilot flame for| flashback ignition of the burner. As shown, the fuel' portions of the 'upturned flanges' plate 26 tion 33 having an opening 34 provided inthe bottom wall, and outwardly extending trough shaped arms 35 which when assembled to the plate 26 terminate adjacent the burners I2 at the cutaway portion 21 of the deflector plate. The ignition member is attached to the plate 26 so that the open sides of the troughs are closed by contact with the plate to thus form fuel flow passages. The ignition member 32, as shown, is held to the underside of the plate 26 by provision of bolts 36 which extend through the plate and arms 35 andV position the member 32 so that the central opening 34 stands aligned with the pilot light 30 and the troughs 35 extend toward the burners I2. Also, the member 32 is attached to the plate 26 so that the cup shaped portion 33 and opening 34 stand vertically aligned with an embossed portion 3l on the interceptor Vplate in which an opening 38 is provided; the opening 38 serving as avent hole for the pilot flame.

The burners I2, deflector plate 26 and the pilot 30 are all carried on common supporting means shown in the form of spaced bars 40. These bars 40 extend from side to side of the stove and are attached to some part of the stove structure such as the flange 20 of the cooking top frame. As shown, the bars 40 have spaced openings 4I for the attachment of the various parts supported thereon. The burners I2 are provided with laterally extended lugs 42 having a fiat bottom face 43 from which spaced pins 44 project for entrance within openings 4I of a bar. 26 has downwardly extending lugs 46 which terminate in pins 4'Ireceivable in other of the bar openings 4I. The pilot 30 is carried in a plate 48 from which ears 49 project and overlie one of the bars 40. rThe ears 49 have openings to receive bolts 50 which attach to openings 4I of the supporting bar.`

'I'he pilot light supporting plate 48 may be formed with an upturned flange 52 which is concentrically related to the pilot jet 53. 'Ihe ilange 52 cooperates with the bottom wall of the ignition member central portion 33 so as to provide a secondary air inlet for the pilot burner` which is of controlled size. Primary air enters through an opening 54 in the pilot 30.

The provision of the single pair of cross bars which serve as supporting means for the various parts of the stove permits accurate alignment of these parts so that they are readily maintained in proper operating relationship. As the holes 4I are pre-formed, and the engaging pins and openings of the various parts all bear a definite Arelationship to each associated part, it becomes a very simple matter to assemble these stove parts accurately. The deiiector plate is further located by` provision of outwardly extending lugs 55 which project from the plate sides to engage the cooking top frame flange so that ,when placing the deilector plate in assembled position these lugs serve as guides for directing the movemen of the plate.

While the form of apparatus herein described constitutes a preferred embodiment of the invention, itis to be understood-that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which 'is dened in the appended claims.
