ATTAoHMENT FOR sas-srovns.

To allvrhom it may concern:

it known that I, (irlonon Hnuznsuonn, j; abject of the Emperor of Germany, residing at Trenton, in the county of Mercer dncl State of New Jersey, have. invented new and useful Improvements in Attachments for Gas-Stoves, of which the-following is a specification.

This invention relates to improvements in attachments for gaseous fuel burning stoves and haspart-icular applieationto a. heat conserving device.

In carrying out-the present invention, ity

is my purpose to provide a heat'conserving device for gaseous fuel burning stoveswhereby the heat from the burner will, be con- *centrated around the burner and delivered to the utensils supported aboveztbe burner, and then delivered to a heat retaining element disposed below-a second utensiland adapted to heat such second utensil by the heat received from the burner.

is a top plan view of a heat conserving device constructed in accordance with the present invention. Fig. 2 is a longitudinal sec tional view therethrough showing the same applied to a stove. Fig. 3 is a bottom plan view of the device. Fig. 4 is a sectional view on the line 44: of Fig. 2. Fig. 5 is a similar view on the line 5'5 of Fig. 2.

Referring now to the drawings in detail, 1 designates a plate formed with an opening 2 adjacent to one end thereof and a relatively small opening 3 adjacent to the other end thereof. Depending from the bottom of the plate 1 and surrounding the openings 2 and 3 and extending longitudinallv of the plate is a flange 4 having the central portions thereof between the openings 2 and 3 disposed in close proximity to each other and eoiiperating with that portion of the plate between the openings to form a passage that connects the open- Specification of Letters Patent.

ings. The upper surface of the plate 1 con centrically of the openings 2 and 3 is rabbeted as at 5 to form seats. and secured to the lower edge of the flange 4 and preferably of a configuration corresponding to that of the flange is a plate (3 serving to close the'lower end of the space formed by the flange. In the present instance, the plate 6 embodiesa stationary section 7 and a movable section 8 and the movable section 8 is disposed below the opening 2 and has one end edge thereof hinged as at 9 to the endportion ofthetlange 4, and the remaining-end edge adapted to abut the adjacent end-of thestationary section 7 of the plate. A lug 10 is pivoted to the under surface of thestationary section 7 of the plate and is adapted to engage the adjacent portion of the movable section 8 to hold the latter in closed-position. The movable section 8 ofthe plate is formed with segmental slots 9', 9' placedend to end and arranged con-- centrically ofthe axis of the opening 2 and disposed within the slots and suitably secured therein are foraminous strips 10.

Disposed within the end of the flange 4 below the opening 3 and suitably secured therein is a heat retaining element 11 in the form of a soapstone or the like and preferably circular in formation andhaving the upper surface convexed as at 12 and the lower surface concaved as at 13. This soapstone is formed with vertical passages 14 to facilitate the circulation of air through the stone so that such air mav be heated when the stone is in a like condition. Suitably secured to the stationary section 7 of the bottom plate 6 below the heat retaining element 11 is an auxiliary burner 15.

In practice, the plate 1 is placed upon the stove and the end of the flange 4 surrounding the opening 2- incloses the main burner of the stove, as elearlyillustrated in Figs. 9. and .4. The auxiliary burner 15 is connected up with the supply pipe of the main burner by means of a. pipe 16 and located in the pipe 16 is a cut off cock 17 equipped .with an upwardly projecting handle 18 exopen position, while when it is desiredtode crease the amountof air fed to 'theburner the plate over the openings 2 and 3 and are supported by the seats 5, 5, thereby closing .the openings 2 and 3 to prevent the escapeof heat aroundthe utensils'or receptacles. The main burner below the opening 2 Is now lighted and the heat therefrom 1s concentrated around the bottom of the pan by the adjacent portion of the flange 4 and passes through ;the passage formed by the central portions of the flange and the corresponding portions of the plates 1- and 6 and heats the soapstone heating element 12. "As the'el'e Inent 12 is heated, the air circulating through the passages l-l impinges against Jacent to" the opening 3disformed-with an outlet aperture '21 designed toep'roxnote c'o'In-" bustion. \Vhen it is desired to feed air to the main burner below the opening 2, the.

movable section 8 ofthe plate 6 is swung to the plate is closed, and the burner supplied with a small quantity of air by means of the foraminous strips IO'in-the .openings-9 of:

is supplied with fuel andslightdand afterplate 22 whereby the heat fromthe mainburner-is 'deflected through the passage and againstthe heating 'element 12. The mar-- ginal edges'of the plate 1 are preferably downturned as at 23 and are designed to rest upon theadjacent portions of the stove to support the device in proper position.

While Ihave herein shown and described one 'ireferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation 1na v* he inade within the scope of the elaimwithout departing from the spirit of the invention. 55

I claim: A heat conserving device for gas ,sto
