STOVE.

Application filed Gctober 3, 1921.

To all whom t may concern.'

Be it known that l, ELnnn'r S. FPooL, a citizen ol the `United States, residing at Hattiesburg, in the county of Forrest and State of Mississippi, have invented new and useful improvements in Stoves, ot which the following is a speciiication.

The present invention has reference to knock-down or collapsible bodies in which the parts constituting the same may be set up in an easy manner to produce a strong and eiiicient structure, and wherein said parts may be easily separated and readily handled to arrange one on the other to produce a small compact package for shipment or for storage.

The improvement is particularly directed to heating apparat-us, such as stoves or builtout heaters for open grates or tire places, and in carrying outl the invention it is my purpose to produce such devices in which the parts thereof can be associated in an easier and more expeditious n'iauner without the employment ot bolts, rivets or analogous securing means.

lt is also my purpose to produce a knochdown structure in which every element constituting the same is provided upon its confronting and abutting surfaces with integral means designed tor inter-engagement in a manner which will hold all ot the parts together in a strong and efficient manner without in any ways detracting from the appearance ot the structure.

It is a still ii'urther object to produce a heating apparatus in which a collapsible or knock-down body rests and .is secured on a. collapsible or knock-down base, one in which the draft damper is ot a particular construction and associated with the stove in a novel manner, one in which the tire 'door .is normallyllocked by means on the front or side oi the stove which cooperates with the door, one in which the hinged connection between the tire door and the stove is such as to sustain'tlie said door in horizontal position when opened, one in which the ash door comprises a removable element and has associated therewith the damper tor controlling the air currents beneath the Serial No. 504,856.

grate, one in which the grat-e comprises removable sections which are arranged in the body ot' the stove in a novel manner which will permit ot the removal thereof when desired, and also one which shall embody various novel features ot construction and arrangement ot parts such as will hereinafter be more fully set Jforth.

a rIhe drawings, which accompany and form part of this application, illustrate a satisfactory embodiment of the improvement reduced to practice, but the nature ot the invention is such as to render the same susceptible to various changes and modifications such as will fall within the scope of what is claimed, and therefore the drawings and description are to be considered in connection with only one embodiment ot the improvement.

It is, or course, to be understood that the improvement is to be constructed in various sizes, shapes, etc., and that any desired material, suited tor the purpose, may be employed.

ln the construction illustrated in Figures 1 to 8, in particular, the base oi the heater comprises tour sections, which are in the nature of plates. The trent plate, indicated oy the numeral 1 has its ends hanged in the same direction, as indicated by the numeral 2, and the inner face ot the said plate, from the bottom thereof, and in a line with the lianges, but spaced therefrom, is integrally formed with lugs el, the upper ends ot' the lugs being reduced or cut away upon their inner aces to provide tongues d. rihe side plates 5 are provided at their upper Jfront corners with lugs 6 which are cut away at the bottoni to i'orm tongues 7. Similar lugs 8 having tongues 9 are provided on the side plates at their upper rear corners. r1`he outer edges of the lugs just mentioned are lush with the outer edges ot the corners of the side plates. rlhe back plate 12 is similar in construction to the front plate being provided with inwardly directed flanges 13 at each end, and having lugs 11 termed with tongues 10 near each end at the bottom of the plate.

To assemble the base the lower part ot the side plates 5 are placed inside ot the ilanges 2 and 13 0n the front and rear plates respectively, and the plates 5 are then slid downwardly in the space between the tlanges and the lugs of the front and rear plates. The tongues 7 on the lugs 6 will interengage with the tongues on the lugs d, and the tongues 9 on lugs 8 will interengage with the tongues 10 on the lugs 11. lt is thus apparent that the parts will be held together, and maintained in position, and that the only movement allowed by such arrangement is the upward movement of the side plates. rlhe side plates 5, at the center thereof have their upper edges notched, as at 141. rlhe bottom plate of the stove proper is oi a materially greater length and width than the supporting base therefor, the under face o'l the bottom plate 15 is straight or smooth throughout, and simply rests on the upper edge of the base, the rear edge ot the plate 15 being disposed in a line with the back of the base. rEhe bottom plate 15, upon its upper face is provided with slot 16 that is designed to align with the notches 111 in the sides 5 of the base, and inward of the slot there are integrally formed on the plate 15 ribs 17, the said ribs having thei ends engaging the ends ot the transverse rib 18 as shown in Figure 3 of the drawings and said ribs 18 are formed adjacent to the rear edge of the bottom plate 15. The ribs 17 terminate approximately in a line with the iront of the base, being disposed to the rear otl said iront a distance approxi mately equalling the thickness oi the front plate oi' the said base, and approximately in a line with the outer edges oi' the said ribs 17 the plate 153 has other ribs 19, the said ribs 19 being ot a materially greater thickness than the ribs 17, while on the outer edge the plate between the ribs 19 there is a tansverse rib 20 preferably ol a thickness substantiall;v equalling` that of the ribs 17 and 18.

'llhe back plate or the stove is indicated by the numeral 21 and has its lower edge re ting on the bottom plate and in contacting engagement with the transverse rib 18. rifhe haelt plate is provided with spaced lugs 3 that have their lower ends notched from 'lie inner ii'ace oit the plate to provide ongues 24. The lugs 23 are spaced from `Lh'e flanges 22 a distance equalling the thiclo ness ot the side plate 25 ot the stove body.

rllhe baclf` plate 21, on its upper edge is termed with an inwardly directed flange 26.

rlhe side plates 25 have their lower edges approximately centrally formed with extending hoolr-lilre tongues or members 27, the sam-e being preferably integrally formed on the outer faces oi 'the side plates and are designed to be passed through the slots 1G in the bottom plate 15 and to yenter the notches 14.-. en the sides orI the supporting base. Thus, it is necessary to cant the side plates when arranging the same on the bottoni or base plate 15, and when the said side plates ae brought to vertical position the inner and lower edges thereoi will be in contacting' engagement with the longitudinal ribs 17 on the said bottom plate 15.

etere proceeding further it should have been stated that the side plates should be positioned upon the base before the back plate is applied thereto, the said side plates having their rear ends provided with inwardly directed lugs 2S that have their upper ends, on their inner faces reduced to t'orin tongues 2), and these tongues are designed 'to be lengaged by the tongues 24: on the lugs oit the back plate wnen the same is moved in a downward vertical direction toward the base or bottom plate 15. In this manner, the back and side plates are effectively secured on the base. rlhe front ends of the side plates, when arranged on the base are in a line with the front ends oi' the longitudinal ribs 17 et the base or bottom plate 15. The side plates 25 have their iront ends, on their inner races provided with lugs 20 disposed appr( iinately opposite the lugs 23, the said lugs 30 having their inner and upper iaces reduced or cutaway to provide the same with tongues o1. The 'side plates 25, upon their upper edges Cil are approximately centrally formed with inwardly directed flanges 32.

The front of the stove comprises a numberlof sections, the upper and outermost section being in the nature of a frame, and this section is indicated by the numeral 'llhe member 33 is open at its center from its bottom to a point adjacent to its upper edge approximately equalling the width of the sides 34 of the said frame or member 33. The sides, upon their inner faces are formed with vertically disposed flanges,

and inward of the flanges with parallel spaced lugs 35 which are reduced from their inner faces at their lower ends to provide tongues 36, and these tongues 36 are designed to coengage with the tongues 31 of the side plates 25, when the outer edges of the said side plates are received between the lugs 35 and the flanges 34. 1t will thus be seen that the frame member 33 is moved downwardly over the outer edges of the side plates, and when the tongues 31 and 36 are in interengagement, as just described, and the back is secured to the sides, the main body of the stove is set up in an easy but strong and eflicient manner. lWhen the front member or frame 33 is positioned, the outer face thereof is in contacting engagement with the inner ends of the outer and widened ribs 19 on the base or bottom plate 15 which more effectively sustains the body in its set up condition. it will, of course, be obvious that it is not necessary to elevate the baclr or the front frame 33 above the top edges of the 'sides in arranging the baclr and front on the sides, it being merely necessary to arrange the lugs on the said front and back between the lugs on the sides and then move the said front and back downwardly into engagement with the tongues on the lugs of the sides and to permit of the lower edges of the front and bach resting on the base. lft is to be also understood that the interior of the stove is suitably reinforced to prevent the buckling thereof from heat, and preferably the members constituting the body each comprise two thicknesses between which there is a body of non-heat conducting material, 'such as sheets of asbestos, but if desired, the inner faces of the body men'ibersmay be formed of single thicknesses and asbestos facings be secured thereon.

being of a width equalling that of the said walls 37 and being of a thickness approximately equalling that of the depression. 'f he lugs have their upper faces out at a downward and inward angle, providing the same with what l will 'term hoolrs and which are indicated by the numeral 39, and the lower walls of the said lu gs, from their outer faces are also inclined inwardly, as at Ll0. The vertical end walls provided by the depression are in a line with the inner walls of the flanges il), and the opening provided by the member 33 is closed, at the upper portion thereof, by a substantially rectangular frame 111, which also, of course, constitutes an element of the front. rirlhe outer face of the frame 4l, upon the vertical ends thereof are provided with outwardly entend ng flanges L12, a similar flange i3 being proded upon the upper odge thereof, while a je or enlargemei'it is arranged upon the lower edge on the outer face of the frame between the side flanges rEhe side flanges it) on their outer edges are provided with notches, the upper and lower walls of which being arranged at the same inclinations, the upper inclined portions forming what l will term hooks. lhe hooks are indicated by the numeral 45, and the notches by the numeral de. The frame is of a size to be snugly received in the opening of the member and to contact with the walls 3" that surround the opening. 'lhe notches 3G are designed to be arranged over the lugs 3S in the vertiwalls 3i', and the hoolrs of the frame il are designed to coengagc with the hool's on the lugs 33 of the member 33. The lower inclined walls of the lugs on which the hooks -15 are formed, and which are indin cated by tl e numeral el?, rest upon the in clined surfaces l1 of the lugs 38, and in this manner the frame l1 is effectively secured upon the front member rlhe lower flange on the frame l1 has its lower edge disposed a slight but suitable distance below the lower edge of the frame proper which is also true with 1espect to the lower ends of the side flanges on the said i and designed to rest against the said edges and ends of the flanges is the upper ezlo'e of the inner inclined portion i8 of the .n ibined air draft and ash door 49. The :er portion of the combined draft and ash door is flat and received on the base or bottom plate 15 and has its outer edge in contactingengagement with the flange 2O and its ends in contacting` engagement with the flanges 19. rlhe inclined portion s3 has side flanges which are also in Contact with the side flanges 19 when the lower edges of e sides or flanges 50 rest on the bottom ate 15. The inclined base e9 of the combined ash door and air regulator or draft is provided centrally with a T-shaped slot, the longer launch 5l of which being arranged longittnlinally and the shorter and entral branch 5f., being a ranged vertically on the door, and the said inclined portion a8, to the sides of the slot has spaced openings 53 therethrough. rlhe chamber comprises a plate pro-vided with spaced openings and with a central substantially hooked or angle handle lhe outer and widened portion of the handle is ol." a size to be passed through the T-shaped slot at the central portion thereof, which is provided with the branch The plate and hook-shaped handle is then permitted to gravitate so that the reduced portion oi. the handle rests upon the lower wall provided by the longitudinal branch ot the A'ishaped slot, the widened or angle end of the handle being in contacting engagement with the outer surface olf the incld portion a8 olI the ash door. By movin;y the handle longitudinally through the slot, the openings in the damper plate may lie brought to register with the opening in the portion i8 ot the ash door and the dit ft entering the stove through the ash door may he regulated by adjusting the damper plate, as will be readily understood.

The lire door is indicated by the numeral 57 and is in the nat-ure oi a substantially rectangular plate of a size to close the central opening in the traine 4l. riChe lire door 57 has its sides and upper edge provided with outwardly extending tlanges 58 and 59 res spectively, the flanges 58 being notched from their outer edges, as at G0, and the oppose-d walls provided by the notches being inclined in the same direction, as 6l and G2 respectively. rlhe upper inclined wall provides what l will term a tongue, and the traine in a line with the vertical walls provided by the central openingr therein is termed with lugs 63 whose uppi and lower ends are cut at the same inclination, the ripper ends providing what l' will term hooks (Sei. rlhe lugs 63 are designed to be passed through the notches (it), and the door 57 is then permitted to gravitate slightly in a downward direction on the frame to bring the hools 6l thereof into coengageinent with the hooks Ga provided upon the lugs rllhe lire door is held in the trame by providing the said door, upon its inner corners with depending ngers G3 that have their lower ends flanged outwardly, as at 66. rllhe door is canted when the lian-.ged lingers are received in the iframe, and when the door is in open position, the same will be sustained horizontally by the outer face oi the door resting upon the lower lange oit the iframe and by the offset ends GG oit' the fingers G5 being in contacting` engagement with the inner face ot' the trame.

The front member 33 or the stove is provided, upon its inner tace with upwardly projected hooks 67, the said hooks designed to be received in slots 68 adjacent to the intenses The sides a, opposite the l'ront grate member have their iiner faces formed with longitudinal iian- TO, and on these iianges rest the main or basket grate 7l.

The top plate ot the stove is indicated by the numeral 752, and is of a considerably greater width and length than the body oi the stove. The top plate is provided with the usual flanged openings for the reception of the dish-like lids, and is also provided with a smoke pipe outlet 73. The stove pipe 73 may be integrally formed with the top, if desired, and when so formed is arranged at an angle so that other pipe sections may be attached the eto in a convenient manner and properly directed to the liuc opening in e chimney. The ev4 tlet is provided, on one e, 'des with an opening, and on its other with a notch. mhrough the opening is to be passed one end oi' the stem or the damper valve 7G, while the other end et' the stem, which has the handle thereon is received in the notch. ln this manner,

e damper can be easily and quickly applied to the pipe section. The top plate T2, upon its inner face and adjacent to its rear end is formed with a laterally extending [lange (7, and the said flange, upon its outer face and determined intervals is formed with outwardly projecting tongues 7S. rlhe under ot the top is likewise formed, adjacent to its ends, with longitudinal lugs T9 that have one otl 'their ends reduced to provide tongues 80. The top is arranged on the body so that the lugs thereotI are disposed between the t'langes 32 and the front of the body. T e top plate is then moved over the body so that the tongues 8O will engage beneath the iianges 32 and the tongues T8 beneath the flange 2G. rlhe flange 7T, on the top plate, when the lugs are so engaged, will be in contacting engagement with the inner edge of the lange 26, and the sides of the lugs 78 will be in contacting engagement with the inner faces of the side plates ln the manner, as above set toi-th, it will be seen that the various elements constituting a stove, constructed in accordance with this invention, coengage in a manner which will hold the body, when set up, in a strong and eiiicient manner, while at the same time such means may be readily brought out of co engagement; when it is desired to separate ends of the trent grate member 69.

the elements or parts of the improvement.

When so disassociated each of the several parts of the stove may be easily handled and all ot the parts may be arranged one over the other to produce a small compact package for storage or shipment.

In the construction illustrated in Figure 9, and the remaining ligures of the drawings, the in'iprovement is ot a means to close an open grate or lire place 8l. The rear or back of the improvement comprises a substantially rectangular frame 82 of a size to fully cover the grate opening. The frame, upon the lower and closed portion thereof has on its outer face, adjacent to its ends spaced vertical flanges 83 respectively, an upper horizontal flange 8st and a lower horizontal flange 85, the last mentioned flange being disposed between the inner vertical flanges. lThe face 86, instead of constituting four members or plates, as previously described, comprises only three, the outer plate being secured to the side plates in a manner similar to that already described, and the side plates having on their inner and upper ends lugs provided with depending tongues 87 that are designed to engage with similar tongues 88 formed on the inner vertical flanges, the outer vertical flanges being in contacting engagement with the outer faces of the side members of the base. The bottom or base plate has its under face provided with longitudinal or transverse lugs or flanges 89 to receive therebetween the upper edges of the base plate, the inner end of the base or bottom 90 resting upon the referred to horizontal flange on the frame 82. The frame 84 is provided with vertically disposed outer and inner spaced flanges 91 and 92 respectively and at its upper end above the said flanges 91 and 92 with an outwardly projecting flange or enlargment 93. The base 90 is also provided with an inner pair of longitudinal ribs 94 and 95 respectively. The inner ribs 94 and 95 are, in this instance, formed with outwardly extending flanges 90 provided with spaced notches 97. rlhe side plates 98 of the body, at their lower edges are provided with inwardly entending ribs 99 provided with spaced notches 100, and the notches are designed to receive therethrough the tongues provided by the notches 97 in the flanges 96 of the ribs 95, and thereafter to be moved toward the rear frame to bring the notches out of alignment, and the outer faces of the side plates into` contacting engagement with the outer ribs 94, and the inner edge-s of the said plates between the vertical inner and outer flanges 92 on the back frame 82. The front is of a similar construction to that previously described, so that a detailed description thereof is not considered necessary, and also the top 101 is substantially similar to the top plate 72 and coengages with the front and sides in a manner similar to that previously described, the inner edge of the top, in the pre-sent instance, underlying the outwardly projecting flange or enlargement on the top of the frame 82. In a like manner, the removable front and basket portion of the grate are supported. The flue damper, in the present instance, regulates t-he passage between the grate, frame and flue against which the device is positioned, and one of the side plates is provided with an opening 101, the second side plate with ak notch 102 disposed directly opposite the opening, the notch being closed by the top plate 103. rfhrough the opening passes one end of the stem 101iL for the damper 105. Through the notch there is passed the opposite end of the stem, and the said last mentioned end is provided with a` handle portion 106. rllhe damper is in the nature of a flat plate, of a sufficient width to accomplish its purpose, and when the back plate is to be wholly opened to the fine, the handle is moved outwardly to bring one end of the damper against the side plate provided with the notch, the damper then being swung to a substantially horizontal position and moved longitudinally in an opposite direction to permit the end thereof resting on a lug 107 provided upon the inner face of the opposite side plate of the body. Varying forms and designs of interengaging means between the plates or elements constituting the improvement are illustrated in detail in Figures 12 to 15, but as the same coengage in a manner similar to that previously described, and as the manner of such coengagement will be perfectly apparent to those skilled in the art to which this invention relates, a detailed description thereof is not considered necessary.

The stove pipe sections, including the elbows, employed in connection with the stove proper each has one of its ends flanged inwardly and notched, as at 108, and the confronting end of the cooperating section is formed with projecting angle lugs 109 designed to be received in the notches 108, and the sections are given a twist on each other so that the shoulders provided by the lugs will contact with the inner faces of the notched flanges.

It is thought that the foregoing description, when taken in connection with the drawings will amply set forth the construction and advantages of the improvement without further detailed description.

Having described the invention, I claim:-

A knock down stove of the character described comprising a plurality of vertical plates interlocked in a manner to provide a rectangular shaped base, a horizontal bottom plate supported by the base and being provided with slots arranged adjacent its side edges, said bottom plate having its front and side edges extending beyond the front and side plates forming the base, a flange rising from the outer edge of theI front extension of the bottom plate, flanges formed on the bottom plate and having their ends engaging in a manner to provide a rectangular frame, side, front and rear walls rising from the bottom plate and engaging the frame thereon, means secured to the respective Walls for interlocking them in operative position, hook like thumbs clepencling from the side Walls and adapted to be receiveL in the slots of the bottom plate, a fuel door for the front Wall of the stove and a combined ash door and air draft plate having angle bent portions formed thereon for engaging the flange on the front extension 'of the bottom plate and a portion of the front Wall respectively and a top supported upon and secured to the Walls as and for the purpose specified.

In testimony whereof I affix my signature.

ELBERT S. PPOOL.
