STOVE.

SPECIFICATION formingpart of Letters Patent No. 293,973, dated February 19, 1584.

Application filed May 25, 1883.

(No model.)

ters of reference indicate like parts of the in vention.

Figure l is a side elevation of my improvedstove.v Fig. 2 is alongitudinal section through the line x as, Fig. 3. Fig. 3 is a top plan view with the top plate or cover of the stove removed, and Fig. 4 is a front elevation through the line y y, Fig. 3.

A B G D are the walls of the stove. E is the top; F, the bottom.

G G are the grates, the inner rear ends, 9 g, of which are journaled in the bracket H, while the outer ends, it h, extend through the sides of the stove and terminate in square shanks M.

I I are locking pawls pivoted to the sides of the stove, and their free ends terminate in slots, which engage the shanks i i and hold the grates in position. Each pawl is provided with a slot, a, which is passed over a T-shaped stud, a, at about a right angle to the position of the pawl when it is holding the grate up, and this construction holds the pawl securely in place, while at the same time dispensing with the usual bolts and nuts or rivets. A wrench being placed on the shank z i and the pawl raised, the grate may readily be shaken, or it may be lowered so as to dump the coals into the pan J, and the grate G, being independent of the grate G, one may be operated as above without disturbing the other.

K is a removable partition, held in place in the center of the fire-space by the guides la la. The object of this partition is to divide the fire-space into two compartments, and when a large fire is required, as in winter, the parpendently of each other by reserving the opposite sides for their respective use.

6 e are a series of solid teeth cast upon the under side of the top E, in line with the rear fire-wall, L, and, while they allow a free draft from the grate, they prevent the coal from getting on the top M of the oven, and thus obstructing the draft or interfering with the operation of the dampers. Where the teeth have been otherwise attached to the stove-as, for example, to the fire-wall or the top of the oventhey necessarily involve a modification of the ordinary fire-back, which is expensive and unnecessary; but in this case, the teeth being cast integral with the top, no additional expense of this character is incurred. The top plate has also been provided with hollow teeth for supplying air to the fire-pot. The teeth, however, in my stove are solid, and are therefore easily cast with the top.

m is a rigid partition upon the top M, and forms a rear continuation of the partition K when the latter is in place.

N N are separate dampers, their inner bearings, n n, journaled in the rigid partition m, and their outer ends pass through the side of the stove and terminate in square heads if, by means of which the said dampers may be operated. When thestove is used in its double capacity, both fire-boxes are supplied with fuel and the dampers N and N are regulated accordingly; but should it be desired to use the stove only in itssingle capacity, then only one grate is supplied with fuel, and the slide K is elevated as seen in Fig. 4, whereby communication between the respective grates is cut off, and the damper N or N, .as the case may be, of the grate not used, is also closed.

0 is a conical-shaped reservoir, which is adjusted to one or both of the holes over the firespace, the plate being removed; and it may be filled with coal when it is desired to keep the fire up overnight or for a considerable length of time. This reservoir is provided with a cover, 0.

This case is confined to the novel features of the teeth. The fire-box forms the subject 1 by the fuel is prevented from getting into the matter of a separate application, Serial No. draft-passages, as set forth. IO
