STOVE.

Application filed November 13, 1922.

To" all whom it may concern:

Be it known that LHANS FUNnn, a citizen of the German Republic, and a resident of Zittau, Saxony, Germany, have invented a new and useful Improved Stove, of which the following is aspecification.

This invention relates to a stove which permits of being taken to pieces and is intended especially for the heating of rooms and the like and the pieces of which may be composed also by an unskilled person which merely need be capable of placing them upon one another in a certain prescribed succession when also the necessary lines will be formed. The stove consists, thus, or is composed or built up, of. a plurali'ty of finished members, one or several of which may form such spaces or chambers as usual for warming things in them, and to each of these latter pieces or members belongs a plate which servesas rear wall for the respective space or chamber. The upper and lower end surfaces of the stove pieces or members are so shaped that the joints between them need not be tightened by means of loam or the like. Besides permitting of being taken to pieces, the stove allows also of bein'greduced or increased in height so as to diminish or increase the heating surface; it may also be transported from one room to another room and, i f desired, a water-basin may be provided in it.

My invention is" illustrated, by way of example, in the accompanying drawings, in which Figure 1 is a front View of a stove constructed and built up according to this invention. Figure 2 is a vertical section through this stove, the plane of section lying at right angles to the plane of View of Figure 1. Figure 3 is a horizontal section in line AB of Figure 1. Figure 4; is a horizontal section in line CD of Figure 2. Figure 5 is a portion of a horizontal section in line E F of Figure 2. Figure 6 is an illustration similarto Figure 1,. showing a larger stove having a water-basin in its top. Figure 7 is an illustration similar to Figure 2, showing a vertical section through the stove shown in Figure'h, the plane of section lying also in this case at right angles a plan of this stove after removal of the top member covering the water-basin. thefig- Serial No. 600,712.

basin, and Figure '9 is a horizontal section in line A-B of Figure 7. b I

Referring to Figures 15, the base or foot of the stove consistsof a circular plate 1 having a central elevated part 3 surrounded by an oblique surface 2 supporting the annular stove member 5 the lower and upper end surface or edge of which is bevelled corresponding to the oblique surface 2 of the base or foot 1. The annular stove member 5 is not completely closed, but a comparatively broad recess is provided in its front portion, which is closed by a vertical plate 10 extending upwards into similar recesses of the next two stove members 5 and 5 which are shaped like the lowest member 5 The plate or front wall 10 which is circularly curved corresponding to the curvature of the members 5 5 has three quadrangular apertures provided with doors 11, 12,. and 13. The door 11 belongs to the member 5 the door 12 to the member 5, and the door 13 to the member 5. Behind the door ll is an ash-box 4 which is shoved into a guide-recess of the central portion of the base 1. At the upper edge of each of the three members 5 5 and 5, are two oppositelyl'ocated oblong projections 6 which are connected with each other by a traverse 6 The projections and the traverse of the member 5 support a grate 7 which is located above the ash box 4. v

The door 12 of the stove-member 5" is a double door. In the rearof this member is a: fire-bridge S which is supported by, the traverse 6 of the member 5? and isso shaped that its rear or upper edge isin contact with the adjacent wall of the stovemember 5*. The projections- 6 and the traversc (i of the member 5 support a plate 9' forming a top closure for the s-paceem closed bythe stove member 5 i. e. the fire space.

The stove member 5 is traversed by a vertical wall 1% supported by the: traverse of the member 5' and extending upwardsto the like traverse of the member 5) The wall 1d formsthe front wall of the flue portion of the stove member 5' and has at its two vertical edges grooves 16 provided for.

tightening purposes.

, he upper sloping surface or edge of the stove member 5 and the lower oblique surface or edge of the stove member 5 have each a'groove into which is placed a hooplike iron ring 18 wrapped with asbestos or the like and serving as a packing, as well as for reenforcing purposes.

The space between the plate or flue wall 14 and the door 13 is covered with a plate 9. The thus closed space serves for warming purposes. The stove members 5 and 5 are turned for 180 and the recess (which, with the members 5 5", 5, is filled up by the plateglO) is filled up with appropriately shaped pieces 20 (Fig. 2), each of which has inner vertical ledges 21, (Fig. 5) bearing against the adjacent edges of the respective stove member and preventing the respective piece from falling out. The lateral surfaces of the pieces 20 and of the respective stove members have grooves 22 that may receive any suitable packing material, and also the upper and the lower surfaces or edges of the stove members 5 and 5 inclusive, the

pieces 20, have grooves 19 adapted to receive vented from cracking.

a packing material; the same provision is made as regards the joint between the stove member 5 and the top or hood 23, as shown in Figure 2. The hood has a branch 24 which serves for connection with the chimney pipe 25.

The oblong inner projections 6 and the traverses 6 of the stove members 5 and 5* support horizontal plates 9 and 9, and between these plates is a bridge 27 having feet 28 (Figure 1) supported by the'plate 9". The bridge 27 is a flue-forming member which lefthand and righthand contacts with {)he adjacent wall portions of the stove mem- 26 are vertical channels provided in the stove members 5 5 and 5, and 26 are somewhat smaller slots which connect said channels with the spaces enclosed by the respective stove members. Such channels and slots are provided also in the hood 23, as shown in Figure 2.

It is obvious that the hot gases issuing forth from the fire (between the door 12 and the fire-bridge 8), together with the radiated heat, heat the plate 9, the wall 14, and also the plate 9* so that the chamber formed, or the space enclosed, by said plates, etc., is effectively heated, as are also the things therein contained. The fire gases pass upwards in the directions indicated by the arrows in Figure 2. Their way is determined also by the plates ,9" and 9, as well as by the bridge 27, The gases get finally into the hood 23 and escape through the chimney pipe 25.

The object of the slots 26 and 26 is to facilitate the extension in horizontal plane of the inner .portions'of the respective stove members so that the outer portions are pre- That provision is important especially as regards the lower stove members (5, 5 5), whereas the higher members may have, but need not have the slots in question at any rate. Any

how, they are, generally, provided in my novel stove, but their object is then another one, viz, increasing the size of the inner surface so as to improve thetransmission of the heat to the outer surface.

The stove members 5 5 have solely to do with the heating of the room, etc., and there may be, of course, more such members than two, the other ones being constructed practically just like the member 5 and being turned for 180 with respect to each other.

It is obvious that the stove members may be put upon one another by any person, even if unskilled in the art of building up stoves for rooms, and it is just as easy to take the stove to pieces in order to clean the interior of the members composing it. Besides, as the members are of like configuration as regards their diameter and height, their manufacturing costs are low and but a few models are required. The members in one and the same stove may. beexchanged among themselves, for instance if a lower one has got damaged and an upper one can be put in place for it, and the stove may be reduced in height or increased in height, just as required under the circumstances being.

The tightening between the stove members at their joints, as well as the tightening at the sides of the plate 14, is similar to the socalled labyrinth tightening known, for instance in connection with steam-turbines where this manner of tightening has since long been effectively made use of. The grooves 19 remain, generally, free from soot and the like which covers in most cases solely the inner surface of the stove members, but if soot, etc., enters into said grooves and fills them up, the tightening is not diminished but improved.

Bevelling the annular end surfaces of the stove members affords a convenient means of securing them in their proper relative p0- sition when building up ,the stove and contributes in preventing the fire-gases-from escaping through the joints between the stove members, especially because of the zig-zag way through which the gases would have to pass.

If the stove members are circular, as is to r be the rule, they may be made very well fitting one upon the other by turning each upper member for a while upon the lower one so as to grind them together and obtain in this way a good tightening without special means. Another advantage of the circular shape of the stove members consists in the possibility of making the wall plate- 10 with its doors ll, 12, and 13, stand at any desired side which, then, is true, of course, also of the fire-space and of the warming chamber.

, basin.

The passage for the fire-gases, especially in the upper stove members, need not at any rate be zigzag shaped, but may be more or less screw-thread shaped which may be effected, for instance, by turning each tollowing stove member with its bridge or bridges (such as 27/28, or its equivalent) for a certain angle. 1

Referring now to the other form of construction illustrated in Figures 6-9, the lowest stove member 29 is pot-shaped and the uppermost (39) contains and supports a water-basin 11,.the rim or flange of which bears upon a ring 4:4: attached to the upper end surface of the member 39. A discharge pipe provided with a cock 42 or the like is screwed into the bottom of the basin and may be unscrewed from it if the basin is to be removed, for instance for the purpose of cleaning. 43 are handles aifixed to the flange of the basin. The chimney pipe ex" tends upwards from that stove member 39, and the top member or hood 45 has a door 46 through which access may be had to the This latter has a cover or lid 41 consisting of two parts, of which that adjacent to the door 16 is hinged to the other one. The hood 45 consists of sheetmetal in this instance, and it, together with the cover or lid 41*, forms a kind of warming chamber for things.

Reverting to the lowermost stove member 29, this has an inner flange 31 carrying the grate 32, and at its bottom is an ash-door 30. There is, thus, in this case no such plate or front wall as in Figs. 1 and 2. The next stove member (33) forms the firespace and has a fire-door 34;. The upper portion of this member is traversed by a bar 6, similar to the traverses 6 of Fig. 2, and between this bar or traverse and the door 13 is a sheet-metal bottom 7, whereas opposite to this door is a flue-forming wall 14, similar to the wall 14 of Fig. 2. The stove member 5 which is that containing the wall 1-1 and having the door 13 has a top-plate 35 made integral with this member. Above this latter is a low intermediate member 36 having also a traverse like 6 which subdivides the top of this member into a large aperture 37 and a small one that forms the first part of the next portion of the flue. The aperture 37 is covered with, and closed by, an iron plate 7 above which is a horizontal partition wall 35 made integral with the next stove member 5 and holding, together with the traverse of the member 36, a flue wall 14. The stove member 5 forms a warming chamber quite similar to that of the member 5, and the object of making the intermediate member 36 lower than the other ones is to have the second warming chamber lie nearer to the fire. The second warming chamber is, in the case shown,

' turned for 180 with respect to the first, but

1 both may lie on the same side of the stove it the intermediate member is made a little higher and a direction-changing bridge like 27 of Figures 1 and 2 is placed into it.

The bottom of the basin may be inclined in the direction to the front of the stove. Furthermore, the basin need not be circular, but may be oblong, one of its small sides being then directed towards the front of the stove. of course, a cover or lid, and the space or chamber above it may form a third heating chamber similar to that shown in Figure 7. Such a chamber, that is to say, the top chamber, need not at any rate be formed by a hood, but a stove member for instance like 5 Fig. 2) may be used instead of it.

47, Figs. 7 and 9, are vertical grooves having the same object as the grooves and slot- s 26 and 26 of Figs. 4: and 5, viz. preventing the arising of rents or the like in the ease of a rather strong heating of the stove. In horizontal direction the grooves 17 extend not quite to halt the thickness of the wall of the stove members, as shown in Figure 9.

The stove members may be manufactured of any suitable substance, but preferably a ceramic one, such as clay, is employed, but also cement may be made use of. If iron is employed, the inner surface is furnished with a layer or lining of loam or an equivalent material, or the stove members are made double-walled, the space being filled up with sand, kieselguhr, or the like, if desired.

I claim:

1. A stove for rooms and the like, comprising member's, forming each an entire layer, having a horizontal wall and being adapted to be placed one upon the other or others and of which at least three have a lateral recess affording access to the ashspace, the fire-space, and at least one warming space, in combination with a water basin arranged. in the top stove-member; a covering plate for said basin, said plate forming the bottom of a warming space located above the basin in an upper stove member, as set forth.
