` lippumion inea April 9, i903. l serial No. 151.702. (Notieren To ,cr/ZZ whom it may concern.-

Beit known that I, FLETCHER D. SWANEY, a citizen' of the United States, residing atK'ansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Furnace or Stove Fire-Pots, of which the following is a speciication.

My invention relates to fire-pots for hot-air ro furnaces and heating-stoves of that class in which air is supplied tothe fuel through the wall of the {ire-pot for the purpose of effecting a more thorough and complete combustion and thereby economy in the useA of fuel, x5 and has for its objects to produce a structure of theA character named which can be quickly and easily repaired without the assistance of skilled labor and which is of simple, strong, durable, and comparatively cheap construczo tion.

To these ends the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings; in which- Figure l is a central vertical section of the body of a stove or fire-pot shell of a furnace i equipped with a lire-pot embodying my in- Avention, said nre-pot being also shown in sec- -tion on the line I I of Fig. Fig..2 is ahorizontal section taken on the line II II of Fig. 1. Fig. 3 is a horizontal section' on the line III III of Fig. 1 with the grate removed. Fig;

35 4 is a vertical section taken on 'the dotted line IV of Fig. 2, but with the sectional wall of the lire-pot omitted.l

In the said drawings, 1 designates whatA .4 designates a circular casting riveted or otherwise secured in ahorizontal position to the shell 1 and provided in its upper side ver- 5o tically'below groove 3 with an annular groove 5 and with a series of equidistant holes6, opening up communication between groove 5 and the ash-pit chamber below. The base of the groove is also provided between said holes with substantially parallel ribs 7, eX- tending approximately radially of the casting, and depending from the inner margin of the latter at diametrically opposite points are la pair of apertured angle-lugs 8, for a purpose which hereinafter appears. 6o

The wall of the re-pot' is composed of a plurality of sections', having their lower ends ir1`.groove 5 contiguous to its inner wall and provided at their upper ends with laterally-projecting lugs 10 for the purpose of 65, spacing the upper ends of the sections equidistantly, these spaces by preference growing gradually Wider toward their lower ends and constituting slots 11, which admit air to the M shell and having its lower end between ribs 8o 7, which latter thus coperate with lugs 10 forthefpurpose of holding the sections in their proper relative positions.l The lower ends of said ribs are recessed, as at 13, to fit over the outer wall of groove 5, and their upper ends are recessed, as at 14, a sufficient distance to enable one grasping a section to raise it in slot 3 until its lower end is above the plane of the inner wall of groove 5, and therefore in such position that said end may 9o be swung inwardly and the section readily withdrawn from the furnace.

15 designates theri'ng portion of the grate, the same resting upon casting 4 and having y a slotted or skeleton portion 16 projecting 95 downward and inward of the castingand provided to the rear of the centerof the furnace with two or more inwardly-projecting lugs 17.

` 18 designates a cross-bar havingdownroo wardly-disposed hook ends 19 engaging the apertured angle-lugs 8 and with a central upwardly-projecting pivot 20, upon which is loosely mounted the rear section 2l of the rotary portion of the grate, said section being also supported upon lugs 17, hereinbefore mentioned.

At opposite sides of its axis grate-section 21 is provided with openings 22, bridged by cylindrical portions 23, forming hinge-rods for the downwardly-disposed hooks 24 at the rear sid'e of the front section 25 of the rotary portion of the grate, said section being formed centrally with the arm 26, underlying grate portion 16 and projecting radially forward and almost through the tube 27, opening up communication with the ash-pit, said tube being cast by preference with the doorcasing 28, to which the outer shell 29 of the air-chamber of the furnace is attached in the usual or any preferred manner.

To support the front half or hinged section of the grate in a horizontal position, I employ a rod 30, extending across tube 27 and pivoted loosely at one end, as at 31, so as to swing in a horizontal plane, but with some vertical play. The free end of said supporting-bar rests in the angle-socket 32, cast with tube 27 by preference and having its inner arm adapted to limit inward movement of said pivoted supporting-bar and its outer arm sloping upwardly and outwardly to compel said bar as swung outwardly to rise, and thereby slightly elevate that portion of the fuel superimposed i, with reference to the hinge-section of the grate, this elevation resulting obviously in the partial disintegration or loosening of the mass, to the end that when bar 30 is swung from under arm 26 and the latter, with said hinged section, drops to the position shown in dotted lines, Fig. 4, the clinkers or ashes at the bottom of said mass may fall or be easily drawn out by means of a poker through the opening into the ash-pit. In this manipulation of rod 30 it is necessary to open door 33. The latter is provided with a vertically-opening slot-covering door 34, and by opening this door the poker can be inserted vand hooked over the free end of rod 30 for the purpose of swinging the same forward to permit the grate to drop. Through said slot the operator also inserts a gas-pipe (not shown) orits equivalent to lit over or otherwise engage the end of arm 2G for the purpose of shaking the grate in the usual manner, bar 30 of course forming the support for the grate during such action.

For the purpose of removing or replacing one or more of the fire-pot wall-sections, as hereiubefore explained, it is first necessary to drop the front half of the grate part way, and then disengaging its hooks 24 from hingerods 23 remove it from the furnace. The rear half of the rotary portion of the grate is then removed in an obvious manner and bar 18, too, if necessary. The operator can now reach in-if necessary, crawl in-and remove one or more of the wall'sections 9 and substitute others, or in lieu of removing the grate, as explained, the operator can reach in through the fuel-door opening (not shown) and substitute a good for a defective Wall-section.

The ring portion l5 of the grate may be formed in asingle piece, but is preferably composed oE two sections abutting together at their ends,the weight and character of the ring serving to maintain these parts in proper relation to each otherand the remainder of the tirepot, the ring being made in halves to render it more convenient to be secured in or removed from position and, furthermore, in case of injury to enable the owner to duplicate the defective part at a comparatively small expense. When all of the partsl are properly assembled and the fuel is burning on the grate, it will be apparent that the air has access to the fuel not only up through the grate, but also through openings 6 to the air-chambers between the fire-pot wall and shell and thence through the upright slots or air-spaces l1 into the body of the fuel, the penetration of the air into the fuel at these various points resulting in a more perfect combustion and consequent economy of operation.

From the above description it will be apparent that I have produced a fire-pot of the character mentioned which is of such simple construction and organization that the owner of the furnace can make the necessary repairs about as easily and quickly as an eX- pert, and it is to be understood that while I have illustrated and described the preferred embodiment of the invention it is susceptible of modiiication in minor particulars without departing from the essential spirit and scope or sacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A fire-pot, comprisinga shell, an annular casting secured therein and provided with holes at intervals, an annulus surmounting the shell, and fire-pot wall-sections 'resting upon the annular casting and having an upand-down sliding engagement with the annulus.

3. A fire-pot comprising a shell, an annular casting secured therein, and provided with holes and a pair of upwardly-projecting ribs between each pair of holes, an annulus surmounting the shell, and rire-pot wall-sections resting upon the annular casting and detach- ICO ably-engaging the annul-us, and provided with outwardly-projecting ribs iitting between said casting-ribs.
