The full nature of the invention, cthegstructure of :theiinvention, ;the method of its operation and 1 the objects which are attained thereby will be more clearly understood from the following specification and the accompanying drawing in which: Fig. 1 is a perspective view of one form of a solid fuel burning space heating stove for which my invention is designed, the same being shown prior tothe application of my invention thereto; Fig. 2 is a fragmentary view in front elevation of the lower portion of the stove shown in Fig. 1

dissemination of fly ash, according to my invention;

Fig. 3-is a fragmentary horizontal sectional view taken on line III-IE of Fig. 2;

Fig. 4 is 'a fragmentary enlarged sectional view taken on line IV,-IV of Fig. 2;

Fig. 5 is a fragmentary vertical sectional view of the lower portion of the stove showing details of construction; and,

Figs. 6 and '7 are reduced fragmentary front tion of my invention.

Referring to the drawing and more particularly to Fig. 1, there is shown a solid fuel burning, space heating stove H] of a magazine feed type having a staking opening [2 adapted "to be closed by a door l4. The body of the stove is surrounded by I 8 of the stove to form an annular air circulating space 20 which is open at the top and bottom. As 55 and 42.

It willibenoted in Fig. ilrthat z'thereiisia space :betweemthe :npper edge 501' :the man 532 rand upper edge of the rash (pit opening through \Mhichzashes sfiyioutiinto theeroom when the-:grates bare shaken t-by rmoving :sthe handle :28 from side itbasideror andzout. I i

In order to eliminate this condition, I close the space above the upper edge ofthe pan 32 with a fixed strip 36 provided with angularly disposed portions 38 which are suitably secured 'to the wall of theash pit, as at 39. The strip 36is provided with a slot 40 through which thehandle 28 extends and the ends of which limit the to and fro arcuate motion of the handle 28. The slot 40' is permanently closed by a movable strip 42,

which has an opening 4| through which the handle 28 extends. The strip 42 is longer than the opening 40 and is slidably mounted in brackets 44 or the like carried by the fixed strip 36, as shown in Figs. 3 and 4.

When the handle 28 is moved to the left, the strip 42 moves with the handle from the position shown in Fig. 2 to that shown in Fig. 6. Conversely, when the handle is moved to the right, the strip 42 moves from the position shown in Fig. 2 to that shown in Fig. 7. In these positions, as well as in the central position, the slot 40 is closed by the strip 42 so that no dust flies out into the room as the grate is shaken by to and fro arcuate movement of the handle. Likewise, when the handle 28 is moved in and out to dump the ashes through the opening 21, the handle slides through tight-fitting registering openings in the strips 36 The lower edge of the strip 36 overlaps and the upper and side edges of the strip 36 are constructed so as to make tight contact with corresponding surfaces of the ash pit wall and openings.

As will be seen from Fig. 5, the handle 28 projects outwardly beyond the vertical plane of the outer edges of the ash pit opening only when the circular grate 39 is moved outwardly to leave the dump opening 21 in the center of the grate ring 26, unobstructed, for dumping cinders and the like through the opening 21. However, it will 'be seen that if the circular grate 30 is moved inwardly (to the right of Fig. 5) until it closes the opening 21, the outer end of handle 28 will be within or to the right of the vertical plane-of the outer edges of the ash pit opening. The handle 28 is, therefore, in an out-of-the-way position and permits of the closing of the ash pit door 22 except when said handle is pulled out to dump the ashes.

, It will thus be seen that in order to provide a removable container 32, of the type set forth, in a stove of the type set forth, and in order to permit of shaking the grate bars, the container must necessarily be of smaller vertical dimension than the ash pit opening. Therefore, ashes will fly into the room whenever the grate bars are shaken. By my invention, a very simple and inexpensive arrangement is provided, by means of which the escape of ashes into the room is effectively stopped. It will also be seen that the entire invention is carried out by the use of two pieces of thin sheet metal, namely, the strip 36, having the slot 40 and the deflected members 38 which are suitably secured in the interior of the ash pit, and the inner strip .42, which is movable with, and through which the handle 28 extends.

By my invention, it is possible to use a stove of the type illustrated in the living quarters of a house without danger of fly ash dirtying the floor and. furniture every time the grates are shaken, I might add that the type of stove illustrated is especially adapted for use in a living room so that the stack 48 of the stove may be connected to the chimney of the fireplace, and it is therefore essential that means be provided against escape of fly ash into the room. It is to be noted that I have accomplished this result by a simple and inexpensive construction which requires a minimum use of metal since the strips 36 and 42 are made of scrap sheet metal which is left over from the manufacture of the stove, the body I 8 and circulating jacket 16 of which are made of sheet steel.

. What I claim is: 1

The combination with a stove of the character described which includes a, grate, a horizontallydisposed shaker bar carried by the underside of said grate, and an ash pit below said grate, there being an access opening in a wall of said stove ing, a first strip fixedly secured to a Wall of said stove and extending from the top edge of said 'opening to the top edge of said pan, completely to close said space, there being an elongated slot in said strip through which the outer end of said shaker bar extends and in which said shaker bar is freely movable in transverse and longitudinal directions, a second strip at least twice as long as said slot in said first strip disposed along the inner side of said stationary strip in registration with and closing said slot in all positions, said second strip having an opening therein closely fitting said bar and through which said shaker bar is longitudinally movable, means for slidably supporting said movable strip for transverse movement with said bar and a door mounted at a margin of said opening and coextensive in dimensions with the entire opening whereby in closed position said door encloses the front wall of the pan and the first strip.
