TO IJL WHOM IT MAY CONGERN:

`Be itknown that I, F. GILMAN, of Minneapolis, Hennepin county,- Minnesota, have invented'an Improve-` ment in Stoves; 'and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same,` reference being had to the accompanying drawings, forming part of this specification. l

This invention relates to the manner in which the sides and end plates of the stove are formed, and the invention consists iii-constructing the sides and end, and also the top and bottom plates of the stove, in such a manner theta series of vertical Aair-tubes shall surround the stove, and also in the arrangement of the ash-pit and grate, in combination with a heating-stove, in the manner hereinafter described.

Figure l represents a longitudinal section of the stove through the liuc x :a: of fig. 3.'

Figure 2 is a horizontal section through the line y y of iig, I.

Figure 3 is a plan or top View. 4

Figure-4 shows `an edge View of one of the side plates.

Similar letters of referenceindieate corresponding parts.

The principal feature ofmy invention is in providing for the passage of 'currents of air through channels formed by the side and'. end plates of the stove in the manner hereinafter set forth, thus increasing the heating,

surface of thc stove to `a very great extent. For this purpose I construct the side plates and the back end plate `each of two separate pieces, either of' cast or sheet ironT In either'cuse each half of the vertical platos named is corrugated, so as to form a series of grooves or channels extending across their Width or height. When two of these plates are put together the grooves or channels so coincide, and their edges matclu'that tubes will he formed. It is not important that these tubes should be round. The sides may be so cast or made that square,

: 0r angular, or any other shaped holes may be used. The lower edges of ftlese side plates are fitted in the usual manner within a flange cast or formed on the bottom plate, and the'upper edges are fitted in like manner u'ithin a ilangc on the under side of the top plate. p Through the bottom and also through thev top plate of the stove there are holes to correspond with the tubes formed as-above by the sides and end plates, so that the currents of air pass from under the stove upward through the heated sides, and are discharged in a highly heated state above the stove. V r i Arepresents the top of the stovefand the sides, as thc stove appears when' complete. The stove is put together in theusual manner. The novelty consists in providing for currents of air to pass upward through the heated sides, as heretofore described, and in the arrangement of the ash-pitand grate. vC represents the ushpit, and D the gta-te. For the purpose of overcoming many of'the diliculties ncideutto the use ofthe common hcating-stovc, I attach a deep ash-pit to my st ove and place a grate above it, which grate is removable. E represents bars, upon which the gratel rcsts at each end of the tire-place. The Width of the grate and ash-pit is shown in the horizontal section, iig. 2.` It will be seen that this arrangement does not in any manner interfere with the formation ofthe sides and otherplates of the stove, as already described.

lI claim as new, and desire to secure by Letters Patent-4- 4 I. Constructing the side and end plates of a stove in two parts each, in sucha mannerI that when the 'parts are put together air-tubes or apertures shall beformed'hetween them, substantially as herein described.

2. The construction and arrangement of the perforated top and bottom plates, and channelled or corrugated side plates, as herein set forthY for the purpose specific-d. i

3. I also claim the sunken ash-pit and the grate, in combination withn heating-stove, constructed :unl arranged substantially as shown and described.

The above specification of my invention signed by inc this twenty-ninth day of August, 1866.

` F. GILMAN.
