UNITED STATES CHARLES E. JOHNSON, PHILADELPHIA, PENNSYLVANIA. j

STOVE TOP.

Application led March 1, 1921. Serial No. 448.910.

To all whom t may concern.' j

Be it known that I, CHARLES E. JOHNSON, a subject of the King of Great Britain (having declared his intention of becoming a citizen of the United States), residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Stove Tops, of which the following is a specification.

One obj ect of my invention is to provide an improved top which can be used with particular advantage on gas stoves and ranges for the purpose of economically using the heat from the fuel consumed.

Another object` is to so construct my improved stove top that it will include heatconining and distributing portions, certain of which are selectively operative for causing heat from an operative burner adjacent one pot-hole to be directed under one or more pot-holes or to confine the heat to the space below the pot-hole of said operative burner.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a top plan view of a gas stove or range having my improved top thereon,

Figure 2 is a section taken on the line 2-2 of Figure 1,

Figure 3 is a section taken on the line 3 3 of Figure 1,

Figure 4 is an inverted plan view of my improved top showing parts in positions forming a heat-confining space communicating with all of the pot-holes,

Figure 5 is an inverted plan view showing certain of the selectively operative parts having been moved and illustrating certain of a number of possible arrangements of the parts to vary the How of heated air,

Figure 6 is a perspective view of one of a number of selectively movable portions made in the form of gates, and

Figure 7 is an enlarged sectional view taken on the line 7-7 of Figure 5.

Referring to the drawings, my improved top 8 includes a top plate 9 having pot-holes 10 positioned above the burners 11. In the p-resent instance, I have illustrated siX potholes, however, it will be understood that any number of holes may be provided according to the size and character of the range.

The plate 9.has a number of depending portions 12 which are preferably made integral with the plate 9; said portions being arcuate and arranged inthe .form of flanges partly' surrounding the pot-holes 10. These portions 12 are discontinued so as to provide outlets 11a 4betweenparts thereof; the are rangement being such as to provide comparatively short parts 12a of the portions 12 between the outlets 11a; said parts 12a also being secured rigidly to the plate 9 and may be an integral partthereof. Other portions j 13 are made arcuate and in the form of gates'which are hinged to the portions 12; certain of the gates being hinged to the parts 12a. The gates 13 are preferably made of the same height as the portions 12 and parts 12agsaid gates being cut away to form half -hinges as clearly shown in Figures 6 and 7.

which extend into holes 16 in the plate 95 and these projections can be engaged by a key of any suitable character (not illustrated) and the gates can be swung on their hinges into various positions. The arrange ment is such, as shown in Figure 4, that the gates 13, portions 12 and parts 12a form a channel above the burners; said channel communicating with all of the pot-holes 10. It is possible, however, by the movement of the gates to form communication from one pot-hole to another to the exclusion of the other pot-holes, as shown in .Figure 5, so that if one of the burners is being used, a portion `of the heat, which isordinarily wasted, will follow vthe channel prescribed by the portions 12 and gates fromone pothole to the other, or if desired` to confine the heat to one pot-hole, this can be done by moving the adjacent gates to form a complete circle with the adjacent portions j 12 and part 12a as clearly shown in Figure 5. Thus it is possible to prevent the waste of the heated air, escaping laterally from around a burner and cause the same to flow to any of the pot-holes merely by switching thev gates from one position to another.

While I have described myinvention as i l taking a particular form, it will be understood that the Various parts of my invention may be changed without departing from f the spirit thereofy-and l.hence I do not limit myself to the` precise construction-setforth,

but Consider that I am at libertymto make..

such changes andy altera-tions as fairly. vcome Within the scope of the Aappended claims.

Having thus described my inventiorn what I claim as newT and desire to secure by Letters Patent is l. A stove top comprising a top plate having holes g flangesI surroundingl theholes and provided with outlets, and a gateat one sideo'f each outlet adapted to close the-out-V let and7 when opened,v to a'ct as a-'side yWall of a passage from outlet to outlet.
