UNITED STATES PATENT OFFICE.
DAVID STUART, OF PHILADELPHIA, PENNSYLVANIA.
COOKING-STOVE.
Specification of Letters Patent No To all whom 'it may concern.'
Be it known that I, DAVID STUART, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Gas-Consuming Cooking-Stoves, and that the following is a full, clear, and eXact description of the principle or character which distinguishes itfrom all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure l is a middlevertical section from front to back of the stove. Fig. 2 is a cross section in the line e a of Fig. 1. Fig. 3 is a bottom view showing the passages for heated air under the oven. Fig. 4L is an interior view of the grate front, and Fig. 5 is a front elevation of the grate front.
My invention is an improvement in gas consuming cooking stoves described and represented as follows:
For the purpose of heating the air on its passage to the distributer a. it enters aperture a and is passed into and through the middle of the rear vpart of the hollow cross piece or bridge on the top of the stove and thence down through the divider m as clearly shown in Figs. l and 2 and indicated by the black arrows. The distributer a is a narrow boX extending across the stove and is fur nished with numerous small apertures c along its front over the fire, one of which apertures is shown in Fig. l. From the middle of this box there rises an oval shaped neck or passage m which I call the divider (as it divides the draft at this point). Into this neck the air enters from a descending neck piece a which proceeds from the lower wall 8 of the hollow crosspiece, and fits over the upper part of the piece m. When the hollow crosspiece b is in place on the stove, its side ends c, c, open into side passages 25,451, dated September 13, 1859.
r, r, formed under the top plate m of the stove which communicate with openings u in the side plates of the stove, and as the air escapes from the numerous small jets of the distributer it is highly heated and causes a perfect combustion of the unconsumed gases arising from the fire.
I am aware that the top plates or cross pieces or bridges of cooking stoves have been made hollow for the purpose of preventing their cracking and warping and to such a device I lay no claim. I merely claim the use of the crosspiece as a vehicle for hot air to t-he distributer in the manner above set forth. This mode of supplying the hot air to the distributer enables me to use all the heating surface of the grate front for supplying hot air to the under side of the oven which is an improvement on the mode set forth in my application now pending in the U. S. Patent Oiiice according to which, one half the grate front is used to heat air to go to the distributer and one half to the under part of the oven.
Figs. l, 3, 4 and 5 show the arrangement for heating air and conveying it to the bottom of the oven. The air enters the grate front at a2, a2, and circulating among the division plates as clearly shown in Fig. 4L passes down through passages a3 on either side, thence into horizontal passages a, to the cross pipe or passage a5 which is perforated with numerous small holes from which the air impinges against the bottom of the oven.
Combining with the hollow cross piece l), the distributer a constructed and arranged as herein set forth.
DAVID STUART.
