GILES F. FILLEY, OF ST. LOUIS, MISSOURI.

COOKING=STOVE @PECIFICATION forming part of Letters Patent No. 397,844, dated February 12, 1889,

Application filed May 19, 1884. Serial No. 132,104. (No model.)

To aZZ whom it may concern.-

Be it known that I, GILES 1 FILLE'Y, of St. Louis, Missouri, have made a new and use ful Improvement in Cooking-Stoves, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a view in perspective of a cooking-stove having the improvement, and Fig. :2 a vertical section of that portion of the stove with which the improvement is immediately connected.

The same letters of reference denote the.

same parts.

The present invention is in the line of improvement described in the letters Patent granted me J auuary ill, 19547.

In the construction referred to provision is made for the admission of the out-er air into the oven through the door or doors of the oven. In the present instance, and in place of admitting the air through the door of the oven, the air is admitted into the oven through an openin beneath the stove-hearth, substantially as shown in the drawings, where- A represents a cook in g-stove of the familiar form and modified only by the 'improvement; Ii, the stove-oven; C the oven-doors; D, the stove-hearth, and E the opening through which the outer air can enter the oven. The opening leads from without the stove through the wall a and into the oven B, and it is tilled with wire-gauze or nn-forated metal or any equivalent material, 1?. The air to a limited extent can. both enter and leave the oven through the opening E. I think it desirable, however, to provide the oven with an additional opening or openings elsewhere, and preferably by filling or providing one or both of the oven-doors U with wire-gauze, 1', substantially as shown in Fig. l. I do not, however, so far as providing another airopening to act in (pn'neetion with the opening E is coneornei'l, desire to be eontined to the openings in. the oven-doors. The gauze e, as in the original. construction, serves also as a guard against improper interference. That portion of the stove through which the opening E is made may be a door or other structure consistent with. the nature of the improvement arranged in that part of the stove; but it is better For the opening into the oven to be made as direct a one as is practicable.

It is desirable for the outer air to circulate freely through the oven. during the cooking, and to that end the opening E can be used to advantage in combination with other airopenings leading from and to the oven, and especially in combination with. the perforated oveirdoors.

A special advantage derived from taking the air into the oven through an opening beneath the hearth is, that the entering air is less likely to be heated in passing through that part of the stove than when it is taken in through the oven door or doors of the stove, and this advantage is increased when the air is discharged from the oven through the upper part of the opening beneath the hearth, for the hearth and parts usually therewith immediately connected or associated are calculated to interfere with the conduction or radiation of the heat from the fire-box of the stove, and such interference is increased by an outgoing air-current interposed between the tire-box and the incoming air current, whose temperature should be raised as little as possible above that prevailing without the stove.

'herever the term wire-gauze is herein used I desire to include in it perforated metal, or an y perforated ba rri ersuch as perforated tin, for example; and as having perforations of a desirable size I frequently employ that grade of perforated tin known to the trade as No. 1.

.By the term stove-hearth herein used I mean that portion of the stove which is below the fire-place grate, and which receives the ashes either direetl y or through the medium of an ash-pan resting in or upon the hearth.

I elaim .l. A cooking-stove having an ()[lOlllllg beneath the sl'o\'(.-.-hearth leading into the oven and tilled \YlTll gauze, e, as and for the pur poses deseril'led.

2. A cooking-stove having the gauze-tilled opening E l. eneath theheartih. and the gauzelilled oven door or doors, substantially described.
