Borgstrom, Los Angeles, Calif. .vApplication'september 27,-1937, Serial No. 165,815 6 Claims.- (Cl. 126-125) This invention relates to a reversible or rotat able ?replace structure which is capable of being installed'in a position wherein it ?lls an opening through oneor more partitions in order that 5 the ?replace may be rotationally adjusted to pre sent its open side to any one of a plurality of rooms which are separated from each other by thejpartition or partitions in which the ?replace is installed. , ' ' ’ I 10 ' An'object of the invention is to utilize heat in a ?replace structure by‘constructing the ?re place‘in such a manner that while one room is being heated by radiation of heatfrom-an open fireplace, another room would be heated by the 15 conduction of'heat through a closure wall pro vided ior'one side ‘of the ?replace.’ Another object of the invention is to provide a ?replace structure ‘which while heating one room by means of‘an open ?replace and heating 20 another room through a ?replace wall thus safe guards children who may be occupying the lat ter room from direct contact with the ?re within the ?replace. Among other objects of the invention is to 25 provide a superior mounting means for a rotat able ?replace structure; to provide superior means for conserving the heat produced in the ?replace; and to improve upon various details of ?replace construction as will hereinafter ap 30 pear. ' Referring to the accompanying drawing which illustrates what is at present deemed to be a pre ferred embodiment of the invention, Fig. 1 is a front view of a ?replace structure 3 as the same appears within a room which is heated by conduction of heat through the ?re place wall. Fig. 2‘ is a vertical mid-section taken on line 2—2 of Fig. 1. 40 Fig. 3 is a transverse section on line 3—3 of Fig. 2. Referring in detail to the drawing, the ?re place is shown installed within a building struc ture having a floor Hi and a partition I I, said par 45 tition being furnished with an opening l2 adja cent to the ?oor. Above said opening I! there is built into the wall a conically shaped hood 13 which communicates at its upper end with a wall ?ue I4. In the lower portion of the partition opening !2 is built a circular stationary base 15 of any suitable ?reproof material. The rotatable ?re place construction is mounted upon said base and includes a circular base plate l6 which is preferably supported upon said base by means of antifriction balls or rollers I’! which travel upon an annular track member l'lt. Upon said base plate is mounted in a ?xed relation thereto ‘an angular ?replace wall structure 20 external to which is a somewhat more than semi-circular plate-or wall l8, said wall l8 extending up to a point substantially on the level with the lower edge of ‘the conical hood 13. By preference and as shown the angular wall structure 20 is made to simulate a brick wall ?replace interior, while the convexed wall portion I8 is suitably orna mented. ' ‘The rotary portion of the ?replace structure is completed by a frustro-conical shell 22 the lower edge of which vforms an upper continua tion of said curved wall 2!, said frustro-conical 1partlcornmunicating at its upper end with a ?ue tube 23 which communicates with the ?ue I4, the outer wall portions and vthe top cross wall lila. Vent openings I8a are provided to allow heated air to pass through the wall l8 into the room behind the open side of the ?replace. As shown in Fig. 2 the stationary hood [3 does not taper upwardly as rapidly as the rotat able conical member 22 and is also of a some : O 25 what greater diameter at its lower end than the latter member. Also the inner angle of the ?re place wall portion 20 is spaced a considerable distance from the central portion of the convexed wall l8. By this arrangement a hot air chamber 0 is provided between the walls I8 and IQ of the rotatable ?replace construction, this chamber having a lower base portion 24 and an upper portion 25. In order to add to the amount of heat conducted from the inner wall portion of the ?replace the shell 22 is provided in its lower portion and at the back side of the ?replace with an alcove 26 produced by forming a two part angular depression in the wall at this point. A restricted angular throat results between the two parts of said depression, thus producing more efficient heat radiation at this point. The stationary hood I3 is furnished with an open grill work [3a thus affording tapered open ings |3b in said hood through which the hot air 45 radiates from the conical part of the ?replace freely into the rooms. A variety of means may be used to rotate the ?replace structure manually or otherwise through a semi-circumference for the purpose of revers ing the position thereof so that the open side of the ?replace may be transferred from one room to the room on the opposite side of the par tition H. In Fig. 2 of the drawing is shown the ?ue spout 23 having a wheel pulley 30 attached 2 i2,122,635 externally thereto which is rotatediby a beit 3| passing over a pulley 32 ?'xed to The shaft 33 of a motor 34. If desiredi'a crank 35 may be added for manual rotation of the structure. At each side of the rotatable ?replace structure 'a sealing member 33 may be provided, said mem ber cooperating with the moving ?anges 311 which croiwd up close to the wall to make a good closure when the ?replace is turned into registeriwith 10 either of the rooms between which the partition extends. I claim: , hood having an opening fthrough its top portion and said partition having a ?ue vertically above said opening thriiugh said hood; and a ?replace turnable? in a horizontal plane and occupying said opening in said partition, said ?replace h-av- ' ing an open lower side portion and a'lconical “top portion furnished with anrouter wall and with an inner wall in an internally spaced rela tion to said outer wall, thus providing a heat radiating chamber, said. inner wall being fur 10 nished with a ?ne spout which projects upwardly into the aforementioned ?ue in the partition in a 1. In combination, a building structure includ turnable relation thereto, and means to turn said ing rooms separated by an upstanding partition ?replace to present its open side toward the de 15 with an opening through it and a conical hood sired side of said partition, the ?rst recited hood 15 over said opening, said partition having a ?ue having openings through it to admit heat into leading upwardly from the space occupied by the rooms. ' ‘ said hood, and a ?replace in said opening, said 4. The subject matter of claim 3 and, said ?replace having a conical top portion which com ‘?ue’ spout of said ?repiace having a wheel por 20 municates with said ?ue, said ?replace also hav tion which forms a portion of said means for ing a ?replace opening and being turnably ad turning the ?replace. justable to direct said opening towards a selected a 5. A ?replace structure positioned between ad room of aforesaid rooms. jacent rooms and including a conical top portion 2. In combination, a building structure includ above a combustion space, said conical top por 25 ing rooms separated by an upstanding partition tion having an outer heat radiating wall and a 2,5 with an opening through it and a hood over said wall spaced inwardly therefrom, said inner wall opening, said partition having a ?ue ieading upwardly from the space occupied by said hood, and a ?replace in said opening, said fireplace having a top, portion which communicates with said ?ue, said top‘ portion being positioned to di rect heat against the inner surface of said hood, and said hood having an open grill work to allow 135 conducting the products of combustion upward ly from, said combustion space, said inner ‘wall having exteriorly formed in it an alcove which augments the amount‘ of heat radiated by said 3.9 inner wall into the space between the outer and inner wall of said conical top‘ portion of‘ said ‘ ?replace. the heat- to pass freely therethrough. 3. In combination, a building structure in 6. The subject matter of claim 5, and, said alcove consisting'of two opposed angular wall 35 eluding rooms separated by an upstanding parti tion having an opening through it, a hood in said opening extending downwardly rom the part of said partition which is above said opening, said depressions having an angular throatbetween them through which the products of combustion ascend.
