MAGAZINE-STOVE.

SPECFCATION forming part of Letters `Patent No. 252,232, dated January 10, 1&2. Application filed July 25,1881. (No model.)

To all whom it may concern:

Be it known that we, JOHN MAGEE and FRANK A. MAGEE, both of Chelsea, in the county of Suffolk and State of Massachusetts, citizens of the United States, have invented a certain new and useful Improvement in Magazine or Base-Burning Stoves, of which the, following is a full, clear, and exact description,

reference being had to the accompanying drawf 7 is a view, alsoin perspective, of a plate and removable door, which are adapted to be substituted for the doors and plate shown in Fig. 6 in converting a close stove into an open grate.

This invention embraces, first, means whereby a magazine or base-burning stove may be readily converted into an open-grate stove; second, improved mechanism for adjusting the size of the outlet of the magazine; third, means whereby the gas is prevented from escaping through the magazine into the room, and, fourth, the arrangement ot` side and front lights in relation to the grate.

In the drawings, A represents the ash-pit; a, the ashpitdoor; B, the grate; C, the fire-pot; D, the combustion-chamber; cl, the opening connecting the combustion-chamber with the diving-flue cl and with the direct flue d2. E is the magazine. Fis a removableplate-containingdoorsf. This plate is fastenedto the frame of the stove by screwsf, and whent is desired to change the stove from a close one to an open grate this plate F is removed and the pla-te or framef2, adapted to be fastened to the frame of the stove by the screws j", is substituted. This framefz has a large opening,f3, a remova ble blower, f4, and a hood, f5, (represented in Fig. 7,) and when used it gives the stove all the features of an open-grate stove.

The size of the outlet c of the magazine is varied bymeans of the front plate, c', which extending beyond or overlapping the side plates, c4, of the magazine, and by the latch 5, having the graduated notches e6, pivoted at el, and the catch e of the swinging plate c. lIt will be observed that by lifting the latch the plate c may be moved out'or in in relation to the sides c4 ofthe magazine and then locked, and that by so doing' the size ofthe outlet may be increased or diminished as desired. This adjustment permits ofthe use ofeoal of any size.

In order that gas may not escape through the openingci, by which the coal is supplied to the magazine, we have provided, in substance, a double door for closing it, or a door consistiugoftwo plates, the under of which is adapted to close the opening before the upper oney is entirely shut, and any gas that may escape from the magazine past the lower plate is taken from the chamber or recess between them through the escape-holes el into the passage or tlue e, connecting with the direct escape and diving flue.

The door Gr, to more minutely describe it, consists in the upper plate, g, which is pivoted at g', and which, when closed, bears upon the shoulders g2, and the lower plate, g3, which is' secured to the upper plate by bolts or rods g4, upon which it has a slight vertical movement. This lower plate closes upon the shoulders or ledges g5, and the play ofthe plate g3 upon the bolts or rods g4 is such that in closing the door the said plate comes in contact therewith before the plategshuts upon the shoulders orledgesg2.

The fire-pot C conforms to the general shape of the stove, preferably has rounded corners,

and a lining of iron-stone or lire-brick, which,

upon the sides and front, does not extend to the grate B, and the section of the tire-pot between the side and front lining and the grate Bcomprscs inclined grate-bars b. The back of the lire-pot is lined from the horizontal grate B to the point c. i

The stove is further provided with two doors, H, one above the other, on eachside, and in addition to the double door f upon the front and below at the double door H2. These doors preferably have set in their frames transparent mica plates. one set upon a line, in whole or in part, with the portion b of the fire-pot, and the 5o is hinged at c2, and is provided with wings e3,

other set surrounding upon the sides and front roo the combustion-chamber. By means of these doors access to all parts of the lire and lire-pot is easily obtained.

Unlike the ordinary base-burning stove, this stove is made so low that the magazine can very easily be supplied with coal, and when theopen-grate attachment is used the self-feeding magazine is also employed', and We believe that this is the rst instance where a portable open grate has been provided with a self-feeding magazine.

The swinging plate for varying the size of the outlet to the magazine may ot course be upon either side, or at the back ot' the magazine instead ol'at thefront, Without departing from the spirit ot' the invention.

vIt will be observed that the stove is rectangular in cross-section, and that the base portion projects at the front only; also, that th'e fire-pot is reetangularin cross section, and that the magazine is rectangular in cross-section; further, that the mica lights may be used upon the sides or front'ouly. This shape of lire-pot and combustion-chamber and frame of stove enables thefuel to he used to its best advantage, both for heatingand illuminating purposes.

Having thus fully described our inventiomwe claim and desire to secure by Letters Patentot' the United Statesl. A magazine or base-burning stove having the plate or section supporting the doors\ofthe combustion-chamber removable, whereby the stove is adapted to be converted from a close to an open grate, all substantially as described.

2. In a magazine or hase-burning stove, a removable door-supporting front plate, F, all substantially as and for the purposes described.

3. The combination ofthe plate e', forming a portion of one ofthe walls of the magazine, hinged at e2 to the magazine, substantially as shown and specified, and means for moving the same to and from the rernainingwalls ot' the ,magazine to diminish or increase the size ofits opening, all substantially as described.

4.. A magazine or base-burning stove haring interchangeable front plates or sections, each ot which contains the opening to the combustion-chamber, one of which is provided with doors, and the other is adapted to receive a blower, whereby the stove may be used as a close or open grate, all substantially as 4described.
