IMPROVEMENT IN RESERVOIR COOKING-STOVES.

The Schedule referred to in these Letters Patent and making part of the same.

To-all whom it may concern:

Be it known that I, WILLIAM H. J orrsson. of the city of Troy, in the county of Rensselaer, and State of New York, have invented certain new and useful Improvements in (looking-Stoves having Water- Heating Reservoirs, of which the following is a full and exact description, reference being bad to the accompanying drawings, in which, on sheet A Figure 1 is a perspective view;

Figure 2, a horizontal section at the line 2 z, in figs. 3, 4, and 5;

Figure 3, a vertical section at the line y y, 2, 4, and 5 Figure. 4, a front elevation of a section at the line a: x, in figs. 2 and 3; and

Figure 5, a vertical section at, and elevation of some parts'in front of, the line w w, in figs. 2 and 3; all of a cooking-stove in which the distinguishing features of my invention are embodied.

011 sheet 13-- Eigure 6 is a perspective view, and

Figure 7, a plan and partial horizontal section justunder the top-plate, of another cooking-stove which embodies the distinguishing features of my invention; and r I Figure 8 is a plan and partial horizontal section just below thctop-plate, of another reservoir cooking-stove,

in which a portion of my invention is embodied.

Like parts are marked by the same letters in the different figures; and thearrows therein indicate the course of the hot gases of combustion through the stove.

Cooking-stoves have been commonly made with a fire-box, A, (see the aforesaid drawings,) at one end; an oven, B, in rear of the tire-box; a fire-flue, 0, leading from the fire-box along the top of the oven; and descending and ascending tines D E, along the upright rear side J, of the oven, and in communication with the top-flue O, and forward and return-fluesnuder the oven, essentially as shown in the drawings.

In some such cooking-stoves, a water-reservoir, G, has been arranged with its front side 71 directly against a rear upright-plate, t, fin-ming the rear casing of the descending and ascending fire-fines in rear of the oven, while the ends j j, and back sidek, of the reservoir were naked; so that the reservoir was heated merely by the front sidc'of the reservoir being against the back-plate of the stove; and consequently the water in the reservoir was not heated as quick, nor as hot, as is generally required. Cooking-stoves having the above-described arrangement of tire-box, oven, and fire-fines, have also been made with a watel reservoir, G, arranged so that the front side 71, of the reservoir itself formed a large portion of the rear side of the descending and ascending fire-fines inrear of the oven; so that all the hot gases a stove, the hot gases lost heat so rapidly,

of combustion had to pass down directly along or in contact with the front side of the water-reservoir, before passing under the oven. Consequently, in such by giving it out directly to the reservoir before passing under the oven,.that-it was impossible or very difficult to,

heat the'oven, sovas to bake good, when the reservoir was filled with cold or moderately warm water.

Cooking-stoves having the oven, fire-box, and fireflnes, arranged substantially as above described; have also been made with a water-reservoir arranged in rear of the fire-flues, back of the oven, and a flue-space or heating-chambers extended along the front side h, ends jj, and rear side k, of the reservoir all at once, and in communication with the rear fire-fines 'of the stove. But a heating-chamber along the rear side, or the front side of the reservoir, in addition to heating-chambers along the ends thereof, and the descending and ascending tire-fines in front, is unnecessary to properly heat the water in the reservoir, and renders the stove more expensive, and makes it necessary either to have the reservoir much narrower in the rearward direction, and, consequently, smaller than is generally demanded, or to have the upper portion of the stove extended too far rearward. 1

The principal object of my invention is to avoid the aforesaid defects in water-reservoir cooking-stoves, having descending and ascending fire-fines between the oven and the water-reservoir, in rear of the oven; and the distinguishing feature of one part of my 'invention in such cooking-stoves is, the arrangement of heating pockets, or chambers L L, along the two upright ends j j of the reservoir, with apertures, or was sages m on, leading directly into the rear or top tireflue, or fire-fines of the sto've, when the rear upright side It of the reservoir is naked so that, while the reservoir shall'be heated sufficiently by the hot gases of combustion in the descending and ascending flues 1) E and chambers, or pockets L L, I obviate all necessity for reducing t-he'size and width of the reservoir in a rearward direction, and avoid the expense of having a heating-flue, or chamber along the rear side of the reservoir. 4 v

As regards'this part of my invention, itis not necessary that the front side of the reservoir should be close against a vertical plate, or casing, in rear of the tiretlues, in front of the reservoir; nor that there should be any plate between the front side of the reservoir and the descending and ascending flues, in rear of the oven.

The distinguishing feature of another part of my invention in cooking-stoves having descendingand ascending fire-fines D E, along the rear side of the oven, and. in communication with a fire-flue, or fire-tines, over and under the oven 15, substantially as shown by the drawings, is, a water-reservoir, G, having its front side It arranged directly against a plate, or casing, "i, which forms the rear side of the descending and ascending fire-fines, in rear of the oven, in combination or connection with pockets, or chambers L L, extended along the ends j j of the water-reservoir, and having communication with the fire-fines of the stovebypassages m m, so that"while the front side of theh'eservvoir shall be moderately heated by'beingagainst the the reservoir will not abstract heat so rapidly from the hot gases of combustion, as the latter descend in the fine, or fines D or D D,.to passunder the oven, and therefore, will not lessen'the baking capability ofthe oven as much when the reservoir is full of cold or mod-. erately-warm water, as would be the case if the trout side h of the reservoir itself served'as'a portion of the rearv casing of the descending fire-flue, or fire-fines.

Asregards the last-aforesaid part of my invention, the rear side of the reservoir need not be naked.

The distinguishing feature of another part of my invention in cooking-stoves is, a water-reservoir, G, having one upright side, It, arranged directly against a plate, or casing, t, forming the back sidev of descending and ascending fire-fines D E, in rear of the oven, with pockets, or chambers LL, extended alorg the upright ends j j of the reservoir, and in communication, by

apertures, or passages m m, with the fire-flue, or firefiues in front of the reservoir, when the rear side It of the reservoir is naked; so that while the fi'ont side and ends of the reservoir are moderately,- but sufliciently heated without materially lessening the baking capability of the oven, all necessity and expense of having a heating-chamber, or fire-flue extended along the rear side of the reservoir, or between the front side of the reservoir and the casing i of "the fire-fines, is avoided, and the reservoir can be of the greatest practicable width and capacity in the rearward direction, with the least rearward extension of the upper part of the stove.

The distinguishing feature of another part of my invention in a cooking-stove having a water-reservoir, G, arranged in rear of descending and ascending fireflues-D E, back of the oven Bof the stove is, heatingpockets, or chambersL L, arranged along the upright ends j j of the reservoir, when such pockets, or chambers bag out or project laterally beyond the sides of the oven, and have communication with the fire-fines of the stove by passages m m, formed through or in laterally-projecting parts a n of the side-plates 0 0 of the stove, essentially as shown by figs. 1, 2, 4, 5, 6, and 7, and not through apertures in any back-plate i, of the stove, as shown in fig. 8.

By this improvement, the reservoir G can be extended entirelyacross and heated directly by the whole rear side ofv the descending and ascending fire-fines, in rear of the oven, as shown in figs. 2 and 7, andthe reservoir can, therefore, be considerably longer in a lateral direction, and, consequently, of greater capacity for holding and heating water, without being any deeper, nor any wider, in the rearward direction, than when the pockets, or chambers L L, do not project, or bag out lateraily beyond the sides of the oven, and have communication withthe fire-fines of the stove, by apertures in the back casing 45, as shown in fig. 8.

In carrying out my invention, I make the stove either with one descending flue, D, and one ascending fine, E, in rear of the oven, as shown in fig. 7 or with two descending flues, D, and one ascending one, E, as in figs. 2, 4, and ,8; and I have the reservoir either wholly below -the top plate 12 of the stove, as in fig. 6, or mainly below and partly above the top plate, as in figs. 1, 3, and 4.

In casea part of the reservoir shall be above the top plate, I sometimes have a part of the upper portion of the reservoir extend over and form the tops of the chambers L L, as indicated by red lines, at q q, in fi 5.

1 make the water-reservoir of any suitable known materials,-but generally prefer to have the reservoir and the plates of the stove all of cast-iron, and fastened together by lugs, flanges, and stove-bolts, in the usual manner, the reservoir being enamelled on its inner surface, or galvanized, or coated with zinc, or

an alloy of tin and zinc, or other suitable known covering, to keep the inner surface of the. reservoir from rusting.

R is the common damper.

Having thus fully described my invention, I would state that I do not claim a reservoir having a single plate at the-rear of the boiler, with pockets, or chambers at the ends, which, by'suitable contrivances, make a continuation of the usual circulation of three-fine cooking-stoves, but without first passing under the oven; but 1 What I do claim as my invention, and desire to secure by Letters Patent, isa A cooking-stove, having a water-reservoir, G, in rear of descending and ascending fire-fines D E, back of the oven, when the rear side It of the reservoir is naked,

and heating-chambers L L extend along the ends j j of the reservoir, and have communication with the fireflues of the stove by apertures m in, substantially as shown and described.

Also, in a cooking-stove, a water-reservoir, arranged with its front side It directly against the rear casing i, of descending and ascending fire-fines, along the upright rear side f of the oven, when heating-pockets, or chambers L L, having communication, by passages m an, with the fire-fines of the stove, extend along the ends of the reservoir, as lierein shown and described.

Also, in a cooking-stove, a water-reservoir, arranged with its front side against the rear casing t ofdescending and ascending fire-fines, along the rear side of the oven, when the back side k of the reservoir is naked,

and heatingpockets, or chambers L L, having communication with the fire-flue, or fire-fines of the stove, extend along the ends jj of' the reservoir, as herein set forth.

Also, in a cooking-stove, having a water-reservoir arranged back of descending and ascending fire-flues, along the rear side of the oven, the heating-pockets, or chambers L L, extending along the ends of the reservoir, and bagging'out or projecting laterally beyond the sides of the oven, and having communication with the fire-flues' of the stove, by passages through or in laterally-projecting parts a n of the side-plates 0 o of the'stove, substantially as hereindescribed and shown by figs. 1, 2, 4,6, and 7. 1

In testimony whereof, I hereunto subscribe my name, this 16th day of March, 1869.
