HEAT-DISTRIBUTER FOR GAS-STOVES, I

Specification of Letters Patent. Patented NO 23 1915 I Application filed. February 14, 1913. Serial'No. 748,269.

' time to heat a column of air immediately above the position which the gas flame would assume, if not thus distributed.

Further purposes of myinvention will appear in the specification and claims hereto.

I have preferred to illustrate my invention by a form thereof which is practicable, efiicient and relatively inexpensive and which atthe same time well illustrates the principles of my invention.

Figure l .is a vertical section through my distributer and a gas stove burner. Fig. 2 is top plan view of thestructure in Fig. 1. Fig. 3 is broken perspective of my heat distributer. Fig. 4: is a broken vertical section of a gas burner and my distributer in reversed position.

In the illustration, the gas burner l is provided with a series of jets of flame 2 here shown as arranged radially in lines as at 3. In order to prevent the flame from coming in direct contact with the bottom of the pan or utensil, which may be objectionable with utensils having thin bottoms, I place a channeled spacer over each line of jets or of flame and form the upper edge of my attachment as a support for the utensil.

In the preferred position of the attachment shown, I provide a center 4. which may be closed, even if there are no jets at this point in the burner selected, and from which I project radially extending channeled arms 5 having the bottom 6 of each channel close to the jet, causing the flame to spread on each side and come up around the.

edges

7 and 8 of the channel at the same time that the air within the channel becomes heated by reason of the heating of the bottom and sides.

I inclose the space at the center and the annulus 9, surrounding and connecting the radial arms, except as these spaces are open to the channels of the arms, as at lOand 11. The

end walls

12 and 13 about the openings 14 preferably connect with the walls 6 and 7 and the annulus'9 is inclosed by a' circular Wall "15 forming a rim. The distributer is intended to rest upon any ribs 16 of the burner.

- While my heat distributer will ordinarily be sold as an article of manufacture, separately'from the stoves it is intended to cooperate with the form of stove with which it is to be used and is to be provided in shapes and sizes such that the channels will correspond to lines of jets of the burners used,

forming a combination, in each case with the burner for which it is specially adapted.

The structure may readily be stamped from sheet metal to leave the upper surfaces of the

walls

7, 8, 12, 13 and 15 within a single plane, not only for the even support of the pan or utensil, but to retain the hot air effectively within communicating spaces. The direct heat from the flame strikes the bottom of the channel in each case and is divided into two parts on opposite sides of the channel, giving distributed heating effect to each line of jets and giving indirect heating by the heated air within the channels. The central closed space and outer annulus, both closed except for their communication with the channels, are well and uniformly heated from the channels.

It will be seen that I obtain both direct and indirect heating of the pan along the line of the radial arms and that I obtain indirect heating of the pan both within and without the area generally heated by the lines of gas flame. My distributer may also be used in reversed position, as in Fig. 4, to space the pans from the burner and to increase the eifective thickness of metal between the flame and the content of the pan.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination, a gas burner providing a gas flame in well-defined lines of flow, a plurality of channels corresponding to the lines of gas flame, interrupted walls forming an inner compartment communicating with the channels, interrupted outer walls uniting adjoining channel walls and an outer wall surrounding the interrupted walls and defining between it and them an outer compartment communicating with the channels, the tops of the channels and walls lying subthe bottom of the channels.

2. A gas burner having radial gas jets, a plurality of radially disposed channels adapted to lie in line with and over said gas jets, and annulus connecting the radial channels, rim sections around'the inside of the annulus between the radial channels and connecting Withthe edges of the channels,

a rim about the outside of the annulus, a

center connecting the radial channels and rim pcrtions about the center connecting the 10 channel edges, the channel sides and the several rim parts being of substantially the same HELEN I. KAUTEFMAN, WM. STEELL JACKSON.
