EDWIN HUMII-IREVILLE, OF LANCASTER, PENNSYLVANIA HEAT CONSERVER Application filed October 27, 1930. Serial No. 491,467.

This invention relates to heat conservers, and has for an object to provide a device for co-acting with the gas burner, of an ordinary gas range, or cooking stove, which shall in an improved manner, direct the flame from .in the formation of dead air pockets immediately under the utensil which are insulating in nature, and in fact, waste the heat rather than conserve it. I

The present invention, therefore, is directed to a sleeve which surrounds the burner, having air vents therein for the admission of secondary air, and formed to conduct the heat from the burner up to within a relatively short distance from the bottom of the utensil, thereby conserving a much greater portion of such heat than ordinarily results from gas combustion.

An object of the invention is, therefore, to provide a band which shall be adjustable,

I and which shall accommodate itself-to burners of difierent sizes, to surround and embrace the burner, and to extend upwardly to the grid to direct products of combustion and air heated thereby, in a more direct path toengagement with the bottom of the utensil. The invention is directed to other objects and possesses other features of novelty and advantage, some of which, together with the foregoing, will be hereinafter more fully 4 set forth.

In the drawing:

Figure 1 is a top plan view of a conventional gas burner, and accessories, with the heat conserver applied thereto, I

' Figure'2 is a fragmentary sectional view,

taken on line 2-2 of Figure 1,

Figure 3 is a detail view of the band, or sleeve, seen from the exterior, or convex side, and

Figure'& is a top plan view of the band showing in detail, the manner of adjusting to different size burners and securing thereto.

Like characters of reference indicate corresponding parts throughout the several views.

The heat conserver, which forms the subject matter of this application, is adapted to be associated with gas burner installations of various types, here represented by the burner proper A, the grid B, and stove top C. It is to be understood, however, that these features form no part of the present invention, but only the structure to which the invention is applied, and will vary with the as particular construction of different makers,

and the drawing is only illustrative of such devices.

The invention comprises a band 10, of flexible sheet metal, or the like, having slits 11, 7 formed therein, at spaced intervals throughout the major part of its length, and the sections of metal of alternate, or occasional strips, between the slits, stamped inwardly as indicated to form louvres 12.

In the drawing, these inwardly stamped strips have been shown as alternating with 1 the sections remaining in plane with the band,

but it is to be understood, that such proportion as may be chosen, may be so stamped in-, 8 wardly.

At one end, the band is provided with a neck 13, reduced in width, to correspond substantially with the length of the slits 11.

The band 1 0, constructed as stated, which forms the heat conserver of this invention,

is applied to the burner by simply curving it about the exterior ends of the burner sections, as shown at Figure 1, and the louvres 12, will be arranged to bear upon the tops of the arms of the burner, as shown to support the band in position. The band, having been curved about the burner, the reduced end 13 will be inserted through any one of the slits 11, which presents itself, and after being 9 drawn tight enough to provide the adequate support, the inwardly extending end is bent backwardly upon itself, as shown at 14:, thus forming a lock to retain the device in position. 1

It will be obvious, that while the interval between the burners and the grid arms does not vary greatly in diflerent types of burners, there will, nevertheless, be some variation, and it will be perfectly obvious that the louvres 12 may be bent sufficiently at the time of application to properly position the band, to engage snugly against the under side of the grid, as shown at Figure 2.

The products of combustion from the orifices of the burner, and the'air heated thereby, will be directed upwardly by this encirtion. :The louvres, about the circumference of this band, will serve by the introduction of air to prevent the flame from the burner en- 7 gaging against the band, and will also tend 1 bodyinga central inlet flue and-fluesbranchto direct the flame and products of combustion inwardly toward the center, and therefore, toward theflpoint of use. 7

Of course, the heat conserver, herein illus trated, may be modified in various ways with out departing from the invention herein set forth and hereinafter claimed.

The invention is hereby-claimed as follows r 1. The combination with a burner of a band having transverse slits forming louvres a therein, and means at its opposite ends for interconnection to form a hoop, said louvres being compressible for seating upon the burner-to hold thehoop ata height determined thereby. i r

to vary the heights'of certain of said louvres adapted to bear upon the extremities of the arms and maintain the band in encircling position. i

6. The combination with-a gas burner embodying a central inlet flue and fines branchin 'therefrom and spaced'apart, of aband ad ustable to circumference to encircle the extremities of the arms, and louvres formed in the band and compressible to vary the heights of certain of said louvres adapted to bear upon the extremities of the arms and maintain the band in encircling position at a height above the burner determined by the proportion of said louvres so compressed.

7 The combination with a gas burner embodying a'central inlet fine and lines branching therefrom and spaced apart, of a band adjustable to circumference to encircle the extremities of the arms, and inwardly struck louvres formed in the band and compressible to vary theheights of certain of'saidlouvres adapted to bear upon the extremities of the arms and maintain the band in encircling po- "sition at a height above theburner'determined by the proportion of said louvresso compressed.

In testimony whereof I have signed my name to this specification.
