inrnovrnnur IN GOAL COOK-STOVE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY PEASE, of Brockport, in the county of Monroe, and State of New Yo'rk, have invented a certain new and useful Improvement in Coal Cook-Stoves; and Ido hereby declare that the following is'a full and'exac'tdescription thereof, referencebeing had to the accompanying drawings, making part of this specification. 1

Figure 1 is a central vertical section.

Figure 2, a transverse horizontal section. I

Figure 3,'a perspective view of the magazine removed from place.

Like letters of reference indicate corresponding parts in all the figures.

' An especial object of my invention is to combine with a coal' cook-stove a magazine or supply-chamber, which will render it a base-burner. A great ditliculty in adapting ordinary cook-stoves to this use is that owing to their peculiar form and construction, the said magazine or supply-chamber cannot be applied without obstructing the surface devoted to cooking. I

To remedy this difiiculty, I construct my stove in a'peculiar manner, so as .to locate the fire-pot in the centre of the oven, at the same time surrounding and shielding the oven in the particular manner hereafter described, to economize and preserve uniformity of heat; and I also provide a removable magazine fitting over the fire-pot, which may be attached and detached, at pleasure. I I

In the drawings, A indicates the outer case of the stove, which is preferably circular. In this is situated an oven, B, leaving affine-space or jacket, a, all around except through door 6. This flue-space communicates at top directly with escape-pip'e G, by passage 0, having damper d, and at the bottom it communicates wtih flue-space a, surrounding conical ash-pit D, and thence it escapesthrough passage f, and up supplementary pipe 0'. In this manner the downward-flue passage'is produced, the the whole outside of stove, from top tov bottom, is heated. i

. In the centre of the oven is placed the open-topped fire-pot E, having'grate 9 over the ash-pot as usual. Outside this 'fire-pot is placed a jacket, '3, closed at the top and botom, except through air-supply passage 7t, over the ash-pit door. The cold air constantly entering through passageh, fills surrounding space 2', and thence pass ing through perforations It 70, near the top of the fire-pot, and assists in consuming the gases. In the top of the stove,'over the open fire-pot, is made hole, Z, in which sits the baseof a removable magazine or chamber, H, which containsthe supply of coal, in a ma'nn'ersimilar to all base-burnin stoves.

The base of this magazine is provided with jacket m,leaving air-space, n, for allowing air to fiowidownward into the fire-pot, through holespja. This assists in burning the gases that would otherwise escape, and it also lessens the burning out of thebase of the magazine. I

By the construction of the stove asbcfore described, and the employment of the removable magazine, I render the stove a base-burner, and at the same time obviate those objectionsthat attend the use of ordinary square or rectangular cook-stoves, where it is attempted to apply the base-burning principle. By making the magazine removable, I am enabled to relieve the top of the stove entirely of impediments, and leave the whole flat surface to receive a boiler or any other .utensil that it may be desirable to apply. vWhen it is desired to use a reserve supply-of coal, the magazine may be applied in,a moments time;

The fire-pot being situated in the centre of the oven, dispenses the heat equally through all parts, and at the same time the oven is shielded from intensity of heat by the interposed layer of air surrounding the fire-pot in space 2'. By thus shielding the oven from the intensity of heat, byjc'old air inside, and surrounding it by the layer of hot air in flue a, on the outside, I produce a-very even and uniform temperature, which is most effective 'in cooking. Besides this, the same air that shields the oven from the fire-pot, cools the fire-pot to prevent its burning out, and passes into it to assist in consuming the gas.

This arrangement of' thefirtgpotand oven has particular connection with the removable magazine, for it enables the stove to be put in such form that said'magazine can be easily applied or. removed.

Inthe rear of the stove is secured in water-tank, I, as usual. V '-Wh1 1t1 claim as my invention, and desire to seeure by Letters Pat ent, is- The-combinntion and arrangement, with the oven B and central fire-pot E, of thehot-air fine a, surroundingthe oven; and the cold-air flue a, surrounding the fire-pot, the effect being to equalize the temperature of the even by shielding from over heat-nnd cold, as herein'set forth.

In witness whereof, I have hereunto signed my name in the presence of two subscribing Witnesses.

' HENRY PEASE.
