HEATING-STOVE.

Specification of Letters Patent.

Patented J an. 30, 1912.

Application filed September 30, 1911. Serial No. 652,107.

To all whom it may concern Be it known that I, ELI J ACKSON PARKER, a citizen of the United States, residing at Iron City, in the county of Lawrence and State of Tennessee, have invented certain new and useful Improvements in Heating Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to stoves, and more especially to those intended for heating purposes; and the object of the same is to improve the construction of a stove of this character in such a way that air admit-ted from a point close to or below the floor of the apartment in which the stove is situated supports the combustion and also furnishes the air which the fire heats, being divided by and within the stove structure so that the products of combustion are passed up the chimney and the heated fresh air is delivered into the apartment. This and other objects are accomplished by the construction hereinafter more fully clescribed and claimed, and shown in the drawings wherein Figure 1 is a front elevation; Fig. 2 a vertical section on the line 22 of Fig. 1; Fig. 3 a similar section at right angles to that shown in Fig. 2, being taken on the line 33 of Fig. 2; Fig. 4 is a plan view with the top swung aside so as to disclose the damper for controlling the outlet of heated fresh air; Figs. 5 to 8 inclusive are sections through Fig. 2 on the lines 55, (56, 77 and S-S respectively; Fig. 9 is an enlarged inside elevation of the connection between the two parts or members of the wall of the ash pit; Fig. 10 is a section on the line 1010 of Fig. 9; Fig. 11 is a plan view of the top plate of the ash pit; Fig. 12 is a bottom plan view thereof; Fig. 13 is a perspective detail of one of the sections or members of said ash pit; Fig. 14. is a plan view of the top plate for the base.

Broadly spreaking this improved stove is made up of the following instrumentalities, to wit: a base B having an inlet I, an ash pit A superimposed upon the base and carrying the grate G, the fire pot P above the ash pit and a chamber C above the fire pot, these three members being surrounded by a shell S, a dome D surmounting the shell and supporting the top T of the stove in rear a means of communication between the annular space around the fire pot and the space within the top; and it is the specific construction of this fine and the parts associated therewith which constitutes the gist of the present invention. These various members will now be described separately and with as much detail as necessary to bring out the present invention.

The base B consists of a shallow pan 1 supported above the floor line by legs 2 and having through its center a hole 3 surrounded by a depending flange 4t and in rear of said hole a cross partition 5 pierced with openings 6 as best seen in Fig. 8.

7 is a damper moving over suitable guides 8 and having openings 9 adapted to be brought into register with those in the partition so as to admit more or less air to the space behind the same for combustion purposes as will be described below, but the adjustment of this damper has no effect on the amount of air admitted to the space forward of the partition which is the air that is to be heated and finally passed into the room as also described below.

The inlet I is by preference a short piece of tubing 11 secured to and depending from the flange 4 to a point near the floor line as seen in Fig. 1 so as to admit the coldest air in the room, but in some cases I may continue this piping through the floor as seen at 12 in Fig. 2 and admit cold air from a point outside the apartment in which the stove is situated. Therefore I do not wish to be limited in this respect. The shell S is by preference secured to and rest-s upon a flange 14. surrounding the base B, and rises thence past said base, the ash pit and grate, and the fire pot, inclosing all said members as best seen in Figs. 2 and 3; and the former view illustrates how this shell at its front may be provided with doors 15 and 16 for feeding coal and removing ashes respectively.

The ash pit A is made up of a plate (see Fig. lat) which forms the top of the base B; the door 16, two members (see Fig. 13), a special connection as shown in Figs. 9 and 10 between the ends of said members which meet at the rear, and a ring-shaped top plate as shown in Figs. 11 and 12. Assuming that the body of this stove is cylindrical as usual, the bottom plate 20 is of circular outline as seen by the dotted lines in Fig. l-il, its periphery being notched or scalloped as at 21 to produce two side openings and as at- 22 to produce two rear openings between all of which are ears while the front edge of the plate is left intact in a lip 2i over which the ash pan 25 can he slipped when the door 16 is open as will be seen from Fig. 2. Cast upon and rising from this plate is an annular flange it dis posed some little distance inside the scallops and having direrging extensions .2? at its trout ends. and just outside the same are lugs 28 cast upon the several ears and the ends of the lip 24. Mounted upon this plate 20 are two complementary and substantially similar sections or members which, with the door 16, constitute the inner wall of the ash pit A, it being umlerstood of course that the shell S constitutes the outer wall'thermit; and one of said members is illustrated in perspective in Fig. 13. The same comprises a curved body 30 whose lower edge adapted to rest upon half of the rearinost ear 2 3 and to extend across one of the side ears and rest upon that outside the extension 27 of the base plate, and to stand between the flange 26 and the lugs 28, and the front. end of said. body has an outwardly deflected wing 81 provided ata proper point with a groove 32 for receiving the fastening device 34:, shown in Fig. 7 as the nut of a bolt by means of which the door frame 160 secured to this member. Said body 30 carries a bracket 33 on which is mounted the grate G in such manner that it may be shaken or dumped (but I will. not describe the same in detail as it forms no part ot' the present inrention). Toward its rear end the body 30 is pierced with openings 3 for admitting air to the lire and on its outer side it is provided with an upright web 35 cast thereon at such point that it will rest upon the side ear 23 of the base plate as best seen in Fig. 7 when the parts are assembled. The other member forming the wall of the ash pit A is of like construction as far as has been described. The rear ends of these members meet at the center of the bacl; of the stove and are cut off on. an upright line 36 provided at intervals with semi-circular notches o7, and opposite the latter one of said members carries a pair of spaced lin- 38 adaptedv to pass outside the rear end of the other member in. a manner best illustrated in Fig. 10; while a short distance baclr from the n'ieeting edge 36 the members are by preference provided with lugs 39 and 370 for a purpose to appear.

The connecting device for the members above described consists of an upright strip L0 adapted to overlie the crack formed between their meeting ends 36 and to fit between the lugs 39 and 370 as best seen in Figs. 9 and 10, and by preference this strip carries a third bracket 33 for supporting the rear of the grate. l inally bolts ll are passed through holes in said strip, through the registering notches 37 in the two members. and between the pairs of iingigers 2:18 on one of said members, and their nuts t), are applied from the outside as best seen in Fig. it). if preferred the lugs 370 on one men1- her may be so disposed as to enter notches 4-3 in the strip at) as seen in Fig. 9 so as to :reliably connect all. parts and hold the strip from vertical movement, and the heads of the bolts ll will then bear on the inner ends of these lugs 870 as shown. The top plate of ti e ash pit A is a ring best seen in Figs. ll and 12. The body 50 of this ring is flat on top except that it is surrounded by a raised peripheral flange 51 extending all the way around, and adapted to lit closely within the shell S as seen in Fig. 2; and just inside this flange said body is pierced at its sides with openings 52 at points which, when the parts are assembled. will cause them, to stand outside the members l and forward of their webs 353 but in rear of their wings 31. On its lower side (see Fig. 12) this ring is provided around its inner edge with a flange 53 extending around the back and both sides thereof but terminating at its front ends in diverging extensions 57 adapted to stand above those numbered 27 on the bottom plate 20 so that these extensions brace the wings ill of the members 30; and just outside said ilangie 53, are lugs 58 between which and the liange the upper edges of the members 30 are received.

The fire pot P has a tubular body (it) which preferably tapers slightly downward so as to lit closely through the hole in the ring 50, above which it may have exterior lugs (31 resting thereon, and its lower edge is by preference scalloped shown at ('32 while its upper edge has a radially projecting annular flange (33 which its closely within the shell S. The peculiar structural feature of this fire pot is that. while its body as a, whole follows a path somewhat remote from the shell S so as to leave an annular space between them, at the rear side it formed or cast with an obliquely disposed flue section (Bel. whose lower and rear side communicates through an inlet opening 65 with said annular space while its upper end (36 rises slightly above said flange 63, all as best seen in Fig. 2.

The combustion chamber C of the stove is that portion thereof nextabove t-he tire pot. P, and may be formed as desired as it constitutes no part of the present invention. The flue l? is here shown as heavy piece of piping 68 having a bell mouth 67 its lower end communicating with the upper end (56 of the flue section G L within the chamber C, the whole being obliquely disposed and extending upward throughout the chamber and dome toward the center of these members but leaving a clear space between it and the shell S. The dome D has the general configuration of a dome, and just above its lower end it has a surrounding flange 71 which rests upon the upper end of the shell S, its body converging on all sides and'thence upward to a flat top plate 72 having a preferably oval hole 73 at the rear surrounded by a flange 74 over which fits the outlet pipe 0 leading to the chimney, and having a hinged door 75 closing a hole a at the front of said plate as best seen in Fig. l. This door may be used in place of that numbered 15, or the latter could be used without the former, or in some cases both might be employed. This detail forms no part of the present invention. At about its center said top plate 72 is pierced with an opening 7 6 which is controlled by a damper 77 here shown as sliding in a recess 78 and having a laterally projecting handle, see Fig. 4. Around said hole 76 the to a plate is cast with a depending annular tango 79 which forms a bell mouth for receiving the upper end of said piping 68 constituting the flue F. The top T may be of any suitable and by preference ornamental construction, but will have its body 80 provided with a number of perforations 81 so that the heated air therein may escape, and this body should be loosely connected as at 82 with the top plate '72 of the dome. D so that the entire top can be turned aside as seen in Fig. 4: when it is desired to gain access to the door 75 or the damper 77. It is obvious that coal can be fed to the stove through this door, or through the other door 15 if used. The various parts of this stove are of the desired sizes, shapes, proportions and materials, and such changes in details may be made as do not depart from the principle of my invention.

In use, the fire is built upon the grate and the live coals will stand within the fire pot P, fresh air being supplied through the inlet 1. To increase the draft the damper 7 is opened more or less thus feeding more or less fresh air through the partition 5 in the pan 1 of the base B, to the rear under the base plate 20, upward through its rearmost scallops 22, behind the two members 30 in rear of their upright webs 35, and forward through their openings 3 1 beneath the grate G; and it will be seen that the adjustment of this damper 7 is the only means provided for controlling the burning of the fuel. lVhether said damper is open or closed, some, and in fact much, of the fresh air admitted through the inlet I forward of the partition 5 beneath the base plate 20 will pass upward through its front scallops 21, outside of the body members 30 between their wings 31 and webs 35 where this air is heated by its proximity to the ash pit A, thence upward through the openings 52 in the ring 50 and into the annular space around the fire pot P where this air is again and more highly heated by the heat in said fire pot, whence it passes through the inlet opening 65 into the lower end of the flue F and is directed upward and obliquely forward by said flue (across the direction in which the products of combustion are passing up the chimney) where this air is finally heated, and at last it is delivered out the opening 76 (controlled by the damper 77) whence it issues through the perforations 81 in the top T and finds its way into the apartment being heated.

Thus it will be seen that I have produced a stove wherein the cold fresh air admitted and finally delivered into the apartment being heated, is warmed three times; first around the ash pit, next around the fire pot, and finally within the flue which extends upward through the chamber and dome of the stove and may therefore be of considerable length. The outlet of the hot air is controlled by the uppermost damper only, the closing of which simply shuts off escape into the room while retaining that already heated so that at any subsequent time it may be let out into the room and the latter warmed. Meanwhile such portion of the air of the inlet as desired is admitted through the lower damper 7 and diverted from its channel upward into the room, backward behind the ash pit, up a flue of its own and in under the grate, and this air supplies the fire and when burned mingles with the products of combustion and flows upward around the flue F and out the chimney without having come into contact with the air that is to be heated and supplied to the apartment; and thus the burning of the fire is controlled by a single damper at the bottom of the stove. The latter is by preference built up in parts as has been described, and these may be removed for repair or replacement, their specific construction having no bearing on the present invention save as has been described and will be claimed. The lower door 16, which is without a damper, although one could be placed therein if desired, will be opened when it is desired to shake or dump the grate or to remove the ash pan; and as the passage for fresh air is entirely out of communication with the interior of the ash pit, no dust can get into it and the heated air is delivered into the apartment in a pure condition, having been sterilized by the high temperature to which it is subjected on its way from the inlet into the room.
