STOVE.

Specification of Letters Patent.

Application filed October 11, 1909.

Patented Sept. 13, 1910.

Serial No. 522,110.

To all whom itmay concern.'

Be it known that l, Cani. H. MILLER, citizen of the l'uited States, residing at Cleveland. in the 4county of tfuyahoga and State of Ohio, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

This invention is an improvement on the stove or range shown and claimed in joint application, Ser. No. 508,277, in which is described a coiistructiou adapted to util ize gas for starting or kin ng a hard wood fire and in or by which the gas mayy be used to supplement or stimulate the volume of heat derived from the hard fuel itself if such fuel, for any reason, be insulticient.

To these ends, thc invention consists in thc construction and arrangement of parts substantially as shown and described and particularly pointed ont in the claims.

ln the accompanying drawings, Figure 'l shows a perspective view of a range or stove embodying my improvement and having the immediate front sectioned away to disclose the interior construction and relation of parts. Fig. 2 is a .plan view in section on line -w, Fig. 1, a portion of the oven and flue being broken away.

In the above mentioned application au auxiliary. or supplemental gas burner or'v burner tube B is shown in substantially the same position and relation as herein and adapted to cooperate with tire grate G and the hard fuel crib over the same for initial lighting of the tire or for sustaining heat as the conditions may require. The oven is also shown with similar draft lues F about the same to distribute the heatfrom the fire box to the oven as before. But thc entire construction is materially improved as compared with said former a plication in several particulars and especia ly in the manner of supplying air to said burner B and grate G. Formerly said burner was located in the angle between the ash pit and the bottom of the grate next to the end Wall of the range and except as it was protected from above by a shield plate was otherwise exposed in the ash pit and combustion Was supplied with such air as said pit contained.

And the air supply for said pit was received at the lower right hand corner of the pit. The results from this arrangement were good but not the best, as we have now discovered, because combustion of fuel, such as coke, in grate G and combustion of the gas was imperfect.

In the present arrangement the gas burner is housed in a chamber C and the escape of gas is from the side of the chamber, which is its only exposed part and which side is partially iuclosed and sheltered by top plate 35. The said plate extends across the top of said burner chamber and down at an inclination at the front thereof in such relation as to perfectly house the burner from droppings from the grate. Now, having burner B in this position and relation, air is supplied directly thereto from beneath the oven by a duct or channel D between the bottomiplate 31 and the bottom 32 of the range and the side wall 33 of the range and a secondary wall 34 next inward therefrom and extending up to the chamber for burner B, where said inner wall is provided with a series of draft perforations or holes 36 controlled by a slide damper 37. The said duct or channel l) has inlet openings 38 for outside air at its rear, and both the theory and the experience is that air entering at this point is heated en route to its outlet at holes 3G and delivered at a greatly increased temperature to the gas burner. Furthermore, better combustion takes place in the tire box above grate G for the reason that the superheated air when delivered as in this case, at the left vand bottoin of grate G must pass from left to right through the entire body of the fuel in the fire box, thus more uniformly distributing the air than in ny former construction wherein the incoming air supply' naturally was greater at the right hand side of the pit and fire-box than elsewhere because both intake and outlets for said pit and fire box were at the right.

As to all the other features of the range not particularly described herein it will be understood that they are the subject matter of other applications for patents or of patents already issued, and therefore are not claimed herein.

What I claim is:

i A kitchen range and the like provided with a grate for hard fuel and a recess horizontaily in the Wall thereof next beneath said grate and a shield plate over the said recess provided with a series of holes, and a gas burner located in said recess and' adapted to start the fire in the grate when lighted.

2. A kitchenrange having an oven, a fuel pot and a burner chamber next beneath said pot at one side an air duct leading to said beneath said burner', whereby sujiei'heaied chamber from beneath 4the oven and having air s'supplied to both Said burner and the discharge openings next beneath the inner fuel in said fire pot and uniform combustion side of said chamber and a gas burner in said is promoted. l 15 5 chamber.
