HUGH L. GADDIS, F MACOMB, ILLINOIS, ASSIGNOR TO AMERICAN STEEL PRODUCTS CO., OF MACOMB, ILLINOISQA CORPORATION 0F ILLINOIS.

SLOW-BURNING STOVE.

Application filed may 1o,

To all whom t may concern.:

Be lit known that I, HUGH L. GADDIS, citizen of the United States, residing at Macomb, in the county of McDonough and 5 State of Illinois, have invented certain new and useful Improvements in a Slow-Burning Stove; and I do hereby 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 it apper- Vtains to make and use. the same.

My invention relates to,stoves or heaters and in its general objects aims to provide a stove construction which will increase the lateral radiation of heat by compelling the products of combustion to pass close to the lateral wall portions of the stove before they can reach the flue, which will retard the. flue draft so as to effect slow combustion of a fuel which otherwise would burn rapidly, and which will afford ready means for catching and removing the flue drip encountered when certain kinds of fuel are burnt at a relatively slow rate. Furthermore, my invention provides a stove or heater construction in which a single and simple member will readily afford all of the above named objects, in which the said member can readily be removed from the stove and replaced therein, in which the regular fuel door of the stove will afford access to the said member, and inl which the said member will also be disposed in an advantageous osition with respect to the check draft used or controlling the operation of the stove. In employing coal burning heaters for such purposes as the warming of the space under the hover or-hood of a broeder, the/ intense heat produced by burning ordinary coal after the manner generally customary with stoves employed in households would produce a highly excessive temperature, hence it is necessary to restrict the draft of such a stove so as to cause the fuel to be consumed at a much lower rate. It is also highly desirable that the heat should be radiated to a large extent laterally of the stove rather than upwards, for which reason it is important that the hot gases should pass close to the lateral walls of the stove instead of moving practically vertically towards a 'Hue outlet in the top of the stove.

My present invention affords a simple and.

effective construction for this purpose by 1924. :serian No. 712,230.

providing a baflle constructed for ,compelling the hot gases to pass close to opposed walls'of the stove before they can reach the flue, and by restricting the openings between the combustion chamber of the stove and the flue so as to retard the normal draft of the stove to a suitable extent.

-Moreover, when common fuels, such as cheap grades of soft coal, are consumed at the relatively low rate resultin from such a restriction of the stove draft, many of the constituents of the fuel are not entirely consumed. Instead, they are merely distilled off and rise past the batile in the form of unburnt vapors. When these vapors strike the relatively cool flue pipe, they are condensed on the interior of the latter and the resulting condensed distillate trickles down and deposits itself in the form of a ltarry and sticky mass on any ledge below the flue pipe, such as would be formed by such a baille. If the resultingaccumulation is not occasionally removed, the continued depositing of the same will gradually clog the openings adjacent to the baille, thereb seriously interfering with the normal dra t and the proper operationy of the stove. To guard against such occurrences, my invention provides a stove construction in which the drip catching baffle is removably supported within. the stove, and provides a stove with a door through which ythe bame can be readily withdrawn for removing the said accumulated flue drip. Furthermore, my invention desirably provides a stove construction in which the fuel door will afford the needed access to such a fuel-drip Catching member.

I n a still further aspect, my invention provides a vstove construction which will l permit such a removable flue-drip Catching baflle to be employed advantageously in connection with the automatically operating check draft arrangement disclosed in my copending application #712,229, filed May 10,01924 on a broeder stove, and provides a simple stove construction for this purpose in which the said combination baffle and flue-drip catching member affords part of a flue chamber and is disposed so that the check draft air will pass over the top of the baffle and over the drip whip/h may have accumulated on the latter. otiil further Yand also more detailed objects will appear from the following specification and from the accompanying drawings, in which Fig. 1 is a central, vertical and longitudinal sectionl through a heating stove embodying my invention.

Fig. 2 is a' horizontal section taken through Fig. 1 along the line 2-2 and looking upwards.

Fig. 3 is an enlarged perspective view of the combined battle and flue-drip catching member.

Fig. 4 is a fragmentary section of the uppervportion of another embodiment of my invention, namely one constructed without a check draft duct and having a hinged door in the top' of the stove for affording access to the combined bafiie and flue-drip catching member.

Fig. 5 is a section similar to Fig. 3, but showing an embodiment in which the effective riser wall of the battle is carried by the door.

Fig. 6 is a similar section through another embodiment, namely one in which the door is in the front wall of the stove.

Referring first to` the preferred embodiment of Fig. 1, this shows a stove having its main portions composed of three superposed sections, namely a base 1 having a top Q which adords the bottom of the irebox, a firebox `section 3 having rocking grates 4 supported bybit, and a combustion chamber Section5. 'llh'isfcombustion chamber section -iS provided adjacent to its top with an inwardly projecting ledge 6 extending at least along two opposlte sides of this stove and adording a support for the detachable member of the stove.. Supported by the top of the said combustion chamber section of the stove is a top lportion 7, here shown as arched upwards to provide a suicient height above the ledge 6 for affording a flue chamber between the bottom of the said detachable member and the flue collar 8 which carries the usual sheet metal flue pipe. This top portion of the stove has a relatively large opening which can be employed for feeding tuel to thestove and which normally is closed by'a removable doore9.

Supported by the said ledges 6 is `the removable member of my stove, which in the embodiments of Figs. 1 to 3 comprises two portions, namelyv a riser wall 12 extending along the front of the due collar substantially from one side wall. of the stove to the other as shown in Fig. 2, and a bottom 13 which is recessed adjacent to each side wall ofthe stove so'as to afford passages 10 operatively connecting the combustion chamber of the stove with the Hue. For this purpose, l am herev showing the said remov- .embodiment particularly whereby this member may be grasped for removing it through the fuel feed opening in the top of the stove after the door 9 has been detached.

lln employing such a stove lfor purposes where a control of the temperature is highly important, lt desirably provide a by-pass duct 15 leading from the ashpit of the stove to the space between the bottom of the flue collar and the top of the plate 13 which forms the bottom of the bame and also provide a rocking damper 1 6 in the said duct', whereby the flow of air through this duct can be controlled automatically after the manner disclosed in my said copending application.

With the heatingstove thus constructed, it will be obvious from the drawings thatthe gaseous products of combustion cannot move in straight lines towards the flue, but can only reach the latter after passing through the said connecting passages 10 adjacent to the opposite lateral edges of the baffle bottom 13. Consequently, these products of combustion areY compelled to pass close to the two side walls of the stove, thereby increasing the lateral radiation of heat. llt will also be evident that any drip from the flue due to the condensing of unburnt distillate on the relatively cool rlue portions Cwill dow down upon the bottom 13 of the bale, so that the resulting accumulation can readily be removed at suitable intervals by simply withdrawing this batte member from the stove through the door opening and scraping oil" the accumulated deposit., However, since the battle bottom 13 is effectively heated during the normal operation of the stove, the drip caught on the latter is also maintained at a fairly high temperature, so that some of this may be entirely consumed by air passing over the battle both through the said passages 10 and through the by-pass duct 15.

By placing the ledge 6 substantially at the top of the casting which houses the combustion chamber 11A of the stove, ll simplify the casting operation, and since the said .ledge will also tend to deflectupwardly movmg gases towards the interior of' the stove,

this ledge also cooperates in compelling the said gases to flow along paths which will increase the lateral radiating effect the stove.

l-lowever, while l have heretofore described my invention in a highly desir ble suited for use in connection with brooders, l do not wie 'to be 'limited to this use of the same, as my vention obviously could 'be employed also to good advantage in stoves employed. for other purposes. Neither do l'wish to be limited to the use of my invention in cennection with a stove having'a check draft duct leading to the space above the or to other details of the construction and arrangement above described. Obviously, these might all be varied in many ways without departing either from the spirit of my invention or rom the appended claims.

For example, Fig. 4 shows my invention as applied to a stove having a hinged door in its top and having the removable member supported on relatively short ledges. Fig. 5 also shows an inclined door 18 at the top of the stove, but shows this as bodily detachable and as carrying a downwardly extending riser wall 19 which cooperates with a simple horizontal baffle plate 20 in affording the same general effect as that obtained by making the bafflebottom 13 and the riser wall 12 integral with each other after the manner of Figs. 1 to 4 inclusive. That is to say, the flue chamber 21 between lthe flue collar 8 and the baffle bottom 2() (which y flue chamber effectively forms the lower part of the flue considered as a whole) in this instance has its front and rear walls formed lrespectively by the depending portion 19 of the door and by the rear wall 22 of the stove, leaving -only the horizontal baffle 20 to deflect and throttle the products of combustion and to catch the flue drip. So also, the door and the opening for the same need not be in the top of the stove,`

but such a door 23 might be in the front wa-ll, as shown for example in Fig. 6.
