Be it known that I, FRANK P. HoLLowAY, a. citizen of the United States, and resident of Knoxville, Tennessee, have invented new and useful Improvements in Stoves, which invent-ion is fully set forth in the following specification.

This invention relates to improvements in stoves. While designed especially with reference to coal and coke burning heating stoves, the improvements constituting the invention are applicable to stoves, heaters, or furnaces, generally. v

Amongst the principal objects attained are the provision of a structure which lends itself to ease and simplicity of repairs in that all 0f the main parts within the casing or drum may be taken out and replaced through a door of the stove without the use of any tools whatsoever; provision of a combined lire-bowl and grate support, preferably of substantially annular outline and formed of a plurality, preferably two, of interchangeable sections interlocking with each other when assembled in place and formed from the same pattern; the provision of a lire-bowl in the form of a plurality of interchangeable sections, all of one pattern, and adapted when assembled to rest at their lower edges on the aforesaid support; the provision of simple means for `supporting the combined re-bowl and grate support whereby said support may be readily put' in' place or removed, as desired; the pro-vision of parts such as the aforesaid, and particularly the fire-bowl sections, so formed and supported when assembled as to-admit of expansion in service without binding or wedging such as to` interfere with ready removal of parts in making repairs, thereby avoiding the necessity of breaking such parts in order to effect removal thereof as is commonly the case with structures now ordinarily used; and the provision of a structure which by interchangeability of parts such as aforesaid minimizes the number of different parts required to be carried by dealers and also correspondingly reduces the liability of mistakes in filling repair orders and assembling the parts in making repairs. The aforesaid and still-.other objects hereinafter stated or apparent from the description and drawings are realized by what I at Fig. l is a perspective view of a heating stove of well known 'type 1in conjunction with which my invention( is illustrated-as f more particularly shown in other views of the drawings Fig. 2 is a vertlcal sectional'view through a portion of one side of the stove of Fig. 1; Fig. 3 is a top view of the combined firebowl and grate support;

Fig. 4 is a horizontal sectional view showing 'the overlapping of edges of two sections of the fire-bowl;

Fig. 5 is a perspective view of assembled parts of the stove omitting the top, the enclosing drum or casing, and'three of the` live Aroun'd its edge base 10.is formed with'lan.

upstanding annular flange 13 and on the inside of said flange with a horizontal offset or shoulder 14 between which and the floor 11 there is anzupright wall 15. 16 are supporting posts of which there are three all of like construction spaced 90 apart around the b-ase 10. At its lower end each post is offset to forma notch or recess 17 closely fitting over the shoulder formed bythe wall-s 14 and 15 with the extreme lower end sur-V face of the post bearing against the upper surface of the bottom or floor 11 of the base. Opposite each post 16 there is an upstanding lug 18 on the base rising above the flange 13 with its inner face flush with the inner face of said flange. The lower edge of the sheet met-al drum or casing 19 fits closely inside of the flange 13 and lugs 18 on the v edges by suitable screw bolts as shown in Fig. 1, and at its lower edge fitting the base 10 and secured thereto by a' screw bolt 26, F ig.v5. The upper or fuel door of the stove is hinged to a suitable door frame 27 positioned over an opening through the wall of the drum or casing 19 and secured thereto by screw-bolts as best shown in Fig. 1.

A combined fire-bowl and grate support is shown as constituted by two similarly formed interchangeable approximately semi-circular sections 30, 30, each having at one endthereof a projecting tongue 31 with a lug 32 thereon, and at its other end a tongue receiving socket 33 with a cross bar 34 across the open end thereof. When the two sections 30, 30 are assembled and interlocked to constitute the complete annular support, the tongue 31 at one end of each section is engaged in the socket 33 at the other end of each section, with the bottom surface of each tongue bearing downward against the bottom wall of the socket and the top surface of each tongue engaging upward against the underside of the cross bar 34, and with .the lug 32 on each tongue engaging behind the cross bar 34 'of its socket, as clearly shown in Fig. 3. In this position of the parts the engagement of the tongues and sockets will afford the saine strength in resisting downward pressure as if the two sections were made in one piece, while a lifting of the two sections at their points of interlockingwill disengage the lugs 32 from behind the cross bars 34 and permit the two sections to be readily drawn apart and disconnected for removal separately from the interior of the druin. Around the inner semi-circular edge of each support section 30 there is an upstanding flange 35, and around the outer edge thereof a succession of spaced equidistant upstanding lugs 36 and 37, with the end surfaces of the cross bars 34,34 constituting in effect similar lugs. The lugs 37 are larger and longer than the lugs 36, each extending outward over and serving to reinforce a peripherally projecting lug 38 of which there are two on each section 30 and so positioned that when the two sections 30, 30 are interlocked there will be four lugs 38 spaced 90CJ apart. Each lug 38 is notched to t over the lug 21 at the upper end of the post 16 and to rest on the horizontal surfaces or ledges 22 at opposite sides of lug 21. One of the four notched lugs 38 will engage over a lug 39 cast on the inner surface of the ash door frame 25, and at opposite sides of said lug will rest upon horizontal surfaces also `formed on said ash door frame, the shape of lug 39 and its adjacent supporting surfaces being similar to that at the upper end of the posts. The upper ends of the three posts 16 and the lug 39 on the ash door frame being equally spaced at 90O from each other and similarly formed, any one thereof may be engaged by any one of the four similarly formed notched lugs 38 of the combined fire-bowl and grate support, the manner of engagement resisting downward pressure or weight but readily permitting disconnection and removal of the two sections by upward or lifting movement. On each support section 3() there are also two depending inwardly projecting grate supporting lugs or arms 40, 40 so positioned that when the two sections 30, 30 are assembled, as shown in Fig. 3, these lugs 40 will be positioned 90o apart. rlhe grate 41, which as illustrated is of a type ordinarily used in hot blast stoves, rests upon and is removably supported by the four lugs 40, as shown in Fig. 5.

The upwardly flaring cylindrical firebowl is shown as made up of five similarly formed interchangeable sections 42, each section being vertically slotted to provide for ventilation and also having along one upright edge thereof what may be termed an expansion fiange 43 adapted to form an overlapping joint with the adjacent edge of the adjoining section and being also of sufficient width to take up any possible eX- pansion of the fire-bowl sections during their life. A lug 44 is cast on the outer surface of each fire-bowl section 42 near the top and near the edge thereof which is overlapped by the flange of the adjacent section. As shown in full lines, Fig. 4, said lug is thus so positioned as to properly space the sections when new and at the same time so formed that when expansion takes place as the result of service, the flange 43 of the adjoining section will ride over said lug, as shown in dotted lines Fig. 4, without causing disarrangement of the lire-bowl sections. The outwardly curved upper edges of the fire-bowl sections 42 rest against the inner surface of the metal drum or casing 19. At its lower end each section 42 is formed around its inner edge with a notch 45 which engages over the flange 35 of the combined lire-bowl and grate support, saidlower edge of the firebowl sections also fitting freely between the outer upright surface of the flange 35 and the inner upright edges of the upstanding lugs 36 and 37 and across bars 34, wherellO by each fire-bowl section'is confined in place at its lower edge by engaging what is in effectV a channel or groove, with the flange 35 also serving as an inside guard protecting the. entire support, of which it is a part, from any intense heat. As will be apparent, special positioning of the fire-bowl sections along the support therefor is unnecessarywas no matter where the lower edge of a section is positioned valong the flange '35, aplurality of lugs 36, 37 will be opposed to the outer surface thereof to hold the lower end of the section in placei `The fire-bowl sections 42 are of such size and shapey that they maybe readily introduced through the fuel door and properly positioned' in engagement with the combined fire-bowl and grate support and with relation to each other by manipulation thereof by reaching through said door. In the event of necessary repairs or replacements said sections may be readily loosened and remo-ved through the fuel door, the grate 41 removed through the same door, the two sections 30, 30 of the combined support relatively lifted so as to disengage their interlocking tongues and sockets and permit removal of said sections separately through the same door, and all of this, as well as reassemblage of said parts, can be accomplished with facility Without the use of tools or fastening means such as bolts, screws, etc. A lug 46 on the inner face of each 'lire-bowl section near the top thereof may be gripped in handling and positioning said section.
