COOKING STOVE OR RANGE.

SPECIFICATION forming part of Letters Patent No. 477,216, dated June 21, 1892. Application filed July 1, 1891. Serial N0i398 l17| (No model.)

To all whom it may concern:

Be it known that I, FRIEDRICH MARQUART, a citizen of the United States, residing at Cleve land, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Cooking Stoves or Ranges; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to cooking stoves or ranges; and the object of the invention is twofold: first, to provide a cold-air chamber beneath the oven, so as to prevent the heat from striking through to the floor and warping or injuring the same, and, secondly, to furnish a draft of hot air to the fire. In respect to the first object it may be said that when a stove is kept clean in the space beneath the oven through which the heat ordinarily circulates when the stove is in use there is great danger of an excessive amount of heat being developed, which strikes through the lower plate and endangers the floor, if it does not, indeed, injure it from burning. Different means have been employed from time to time to prevent the heat from thus striking through to the floor; but all such means, as I understand them, differ from those employed in this invention. Again, it is well known that there is advantage in having the air that is fed to the fire in a heated condition, as this promotes combustion to just the extent that there are units of heat contained in the air that is fed to the flame. The two objects I have in view are therefore secured by my novel construction of stove, the fresh air entering beneath the oven serving to prevent the heat striking through to the floor and the heat thus taken up by the air being conveyed directly to the fire and adding its heat units thereto.

The invention therefore consists in the construction of a stove or range substantially as herein shown and described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 shows a front elevation of the upper part of the stove and a cross-section of the stove in its body part a slight distance from the front thereof. Fig. 2 is a perspective of my improved stove or range on a scale reduced from that shown in Fig. 1 and having a portion of the right side broken away to disclose the separating plates between the respective chambers at the bottom of the oven.

It will be observed that the range here shown is provided with a fire-pot A at the left-hand side thereof immediately beneath the first two holes or openings for vessels. From this point a flue or heat-passage B extends to the right across beneath the other four openings on top of the stove and thence down at the righthand side and under the oven, the heat-pas sage B beneath the oven occupying the entire width of the oven and having a top plate C, which forms the bottom of the oven, and a bottom plate D, which forms the bottom of the heated passage or channel, the heat finally escaping through the outlet E, which enters the rear flue F, whence the products of combustion pass off into the chimney. A damper G at the top of the stove is provided, as usual, for short-circuiting the draft into the flue F directly, if desired, said damper G having a handle 9 extending out within convenient reach.

Beneath the fire-pot on the floor-plate proper of the stove is the ash pan or receptacle H, and this receptacle is purposely made somewhat narrower than the ash-chamber, in which it is placed, so as to allow an air-space at its side. It will be observed that the floor or bottom plate I, on which said ash-pan rests, extends entirely across the width of the stove at a suitable distance below the plate D, so that an air-chamber is formed between said plates.

Now in order that the objects of the invention may be attained in the manner and for the purpose hereinbefore described Iprovide a suitable air-inlet K (shown here at the right side of the stove; but it may be at any suitable place, according to the build of the stove) and an air opening or inlet 7c for the air from said chamber into the ash pit or chamber, whence the air is free to travel up through said chamber to supply oxygen to tlre fire. The usual front damper L of course remains in the stove, and may be employed when for any reason it is desirable to keep the damper K closed, or both may be opened at the same time. It will be seen that by this construction the air passing in at K makes more than a complete circuit around the stove from that point to the outlet E and the air in the passage or chamber B beneath the oven is heated without in the least diminishing the heat imparted to the oven. This radiated-heat faciiitates combustion, as hereinbefore described, by adding its heat units to the air, and thus economizing fuel, with a better and quicker fire than can be otherwise obtained.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is i A cooking-range provided with an oven in its body portion, a fire-pot at one side of the oven, a heat-passage from said pot over the oven and around one side thereof and across beneath the bottom of the same, and a freshair passage beneath the said heat-passage 011 the bottom of the oven formed by two plates D and I, and openings for the admission of air to said air-passage, and openings to discharge the heated air into the space beneath the fireopot, whereby heated air is fed to the fire to supplycombusiion, substantiallyas described.

Witness my hand to the foregoing specification.

FRIEDRICH MARQUART.
