\ Application filed February 3, 1910. Serial No. 541,673.

To all whom it may concern:

Beit known that I, CHARLES H. MILLER, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Combined Gas and Hard-Fuel Ranges, of which the followin is a specification.

y invention relates to improvements in combined gas and hard fuel ranges, and the invention consists in that portion of the range which relates particularly to the use ofgas with certain of the cooking holes, substantially as herein shown and described and In the accompanying drawings, Figure 1 ing my improvements, and Fig. 2 is a vertical sectional elevation of the upper portion of the range lengthwise thereof and with the parts shown in position as in Fig. 1. Fig. 3 is a cross section of the upper portion of the the drawingsshows enlarged views of sundry parts. Thus, Fig. 4 is an enlarged front view of one of the gas burner bowls, and Fig. 5 is a front to rear sectional elevation thereof. Fig. 6 is a si e elevation of the neck member for the bowl, and Fig. 7 shows the bowl and neck member united. Fig. 8 is a longitudinal sectional view of the burner.

The range thus shown is a double fuel range or one which is equipped with a fire pot for hard fuel, such as coal or wood, and gas burners for the four several holes of the range as shown.

The present invention has to do exclusively with the holes A and the burners and other parts connected therewith as shown herein, and leaves the entire top of the range open for draft as usual except as the bowls or receptacles C occupy small portions of said draft space and more or less obstruct the through passage from the fire obstruction is not really noticeable in the operation of the range because it is comparatively slight at the most and the products of combustion easily pass about the said bowls and operate to heat the same so as to make the frontholes Av available for cooking the same practically as if the said bow-ls were not seated therein. The said bowls C are shown as seated within the holes A beneath the top plate D of the range and provided in this instance with flanged edges which engage behind corresponding shoulders or otl'sets in the said plate and about the depressions therein to receive the lids of the store as usual, and otherwise such further support for the said bowls as may be needed is afforded by means of project-ions or feet 0 on their bottom which rest upon the bottom F of the flue or draft space in the top of the range. Presumably these howls are placcd in position when the range is assembled and the construction and arrangcment;tln-reof as shown, or the equi\'a lent thereof. serves to" hold the said bowls in position. in this instance I show a sliding damper 2 on the inside of the bowl adapted to cover draft holes in the wall thereof and which may he opened or closed according as one fuel 'or another is used. \Vhen gas is burned, especially natural gas, I prefer to have these dampers open to permit. such draft as a healthful condition would suggest. but when hard fuel is used and the. gas burners (l are idle said dampers are closed. When closed. the bowls are scaled so far as the products of coinbustion from the fire potare concerned and the practical effect and value of the chamber hereinbefore described is obtained with a very much simpler and better construction. The said bowl C has an opening 3 in its immediate front and a separate and attachable neck 4 is shown in this instance as engaged therewith by any suitable means, the-particular means in this instance being a lip or catch 5 upon the top and inner edge of the said neck adapted to engage against the edge of the bowl at that point and an offset lip 6- at the bottom with a screw (l rigidly uniting .the parts. Utherwise the said neck extends through a hole in the front wall of the range. and the burner G- has a stem or shank '7 rojecting out through said neck and relatively smaller than the neck so as to afford a draft of air through the neck to the burner. The usual valve with a valve stem 9 is shown and a mixer 10 for air and gas, and the said burner is otherwise removably seated in the bottom of the bowl C but ordinarily remains in position therein.

If hard fuel is used the bowl serves especially well for stewing foods thereon, and a pan or pot can be set over the bowl with no danger of burning while the contents will quickly rise to a boiling oint. Again, the bowl can be used with t e gas burner and theoutside heat at the same time or separately. When hard coal is burned, whichis slow in coming up, parties often resort adapted to. rest in the hollow feet c ot the .to the gas for the two front burners to get a meal alon more hastily.

'Burners have bottom lugs 8 whi,ch are bowl, thereby fixingv their position there-in.

What I claim is:

1; A combined hard fuel and gas 'r'ange' 'having one or more cooking holes in its top and front and a bowl seated within each of said holesprovided with supporting lugs at its bOlQtOIll and one of said lngs having a cavity open intothe said bowl, in combination with a gas burner having a bottom projection seated in said: cavity.

2. A combined'solid fuel and gas range having a fire pot and provided with a draft passage under its top and cooking holes in its top and front above said passage, a metallic bowl beneath each of said front holes and constructed with a front opening above its bottom and .a draft opening in the side thereof, a damper for said draft opening 'and a tubular extension for said front open- ,A kitchen -range having a draft pas sage and cooking holes in its vtopyin combination with a bowl in the-said draft passage in the top of the range engagedabout its edge within theedge' of one of said cooking holes, said bowl closed at its bottom and having an opening at its front, a tubular neck, projecting through the wall of the range and engaged over said opening, in

combination with a gas'burner removably.

seated in said bowl and provided with a tubular shank extending into said neck.

4:. A cooking range adapted to use both solid fuel and gas and having a draft passage and cooking holes in its top over the said draft passage, in comb nation with a bowl closed-at its bottom" and engaged about:

'ing holes and seated in said passage, said bowl having lugs on its bottom resting on the bottom of said passage and adapted to raise the body of the bowl above said bottom, thereby providing draft space beneath the bowl. p a a In testimony whereof 'I afiix my signature 'in'presence of two witnesses.
