COMBINED CHIMNEY, FURNACE, AND VENTILATOB.

Application filed-February 12, 1925. Serial No. 8,763.

To all whom/it may concern: pit and another branch 14 extending into Be it known that I, ,EDWARD DUDLEY the air heating space 6, said branches hav- Liiwis, a citizen of Ythe United States, reing appropriate valves or dampers 13 and siding at Elmira, in the county of Chemung 14', respectively. Any desired means, such and vState of New York, have invented ceras the blower 15 ,may be used to direct air tain new and useful Improvements in a through the piping, and tlie travel of this Combined Chimney, Furnace, and Ventiair is of course controlled by the valves or lator: and I do declare the following to be dampers 13 and 14.

a full, clear, and exact description of the The inner and outer walls 4 and 5 are invention, suoli as will enable others skilled preferably ofV the same height, and their upiii the art to which it appertains to make per ends support a horizontal plate 16 havand use the same. ing a lange 17 at its edge which surrounds Itis well known that a great deal of heat the wall 5 and may assist in holding a jacket is exhausted and wasted through the ordi- 1 8 around said wall if such jacket is denai-y chimneys and stacks from furnaces and sired. The plate 16 is provided with an other forms of heateis. It is the primaryminnci' relatively small upstanding collar 19 object of my invention however to provide which communicates with the interior of a new and improved Construction whereby thel inner wall 4, and said plate is also prothere will be practically no waste heat, the i'ided with an outer relative yrlarge upstandliot gases discharged from the burning fuel, 111g 6911er 20, suitable heat escape openings being utilized substantially throughout their 21 being fOrmcd through the plate, between travel, t0' heat air, Such air being in turn the inner and outer collars. An outer comused to heat the building in which the im- Paratlfely large pipe 22 is engaged at its moved Structure is Sed lower end with the collar 2() and extends YA further object is to provide for use of nPWaIflly from the Plate 16 through Open the heating system as a cooling and ventilngs 23 1n tlle numerous flQOlS 0f the build' lating system in warm weather. lngf and an Inner Smalle?l Pipe 2 4 lS engaged lVth the foregoing in view, the invention Wltll the Cpllfil' 19, Saul lIlIleI P1P@ being C0- resides in the novel subject matter hereineXtrensive 1 n length with the outer pipe 22. after described and claimed, the description The lWO P11395 nr? held ln Slmcd relatlon by being supplemented by the accompanying Stay-bolts 25 positioned at desired intervals drawing, in which a vertical sectional view and the SPaCB 26 between Said plipes constic makes use shown, installed within 'a building. Olf all heat imparted '[0 thc pipe 24, by the In the drawing above briefly described, discharge of smoke and 'hot gases therethe numeral 1 designates a furnace in the tllI'Ollgll- FOI COIlClllC'lIlg the 110i? all* IOm basement of a building having aplurality of the Space 26, t0 the Several IOOIIIS 0f the oois 2, and the numerals 3 designate parbuilding, appl''pllate Piping 27 may be and 9 designates a door for such pit. At' 10, a moisture panlias been shown, having 22 and 24,- 1s a-cap plate 29 having de endtitions on said oors dividing the building employed, Sdlfl Piping having COIIIOlValVeS int@ rooms, 4 or dampers 28. In addition to controlling The furnace 1 comprises an inner conthe discharge of hot air, these valves or tinuous wall 4 and an outer continuous wall Clampels may bQ'USed t0 SlIIillaIly COIltIOl 5, an air heating space 6 being provided becool air when the furnace is out of operatween the two walls. Within the wall 4, a tionin warm weather and the blower 15 is grate 7 has ybeen shown for burning solid utilized to direct a blast of air into the space fuel, and a fuel door is indicated at 8, it 6, between the inner and outer Walls4 and 5 heilig understood however that gas or oil ofthe furnace. -'I`hus, with a single system, could be consumed instead of solid'fuel, if heating may be eleoted to a high state of desired. In the construction shown, an ash perfection'in cold weather, and cooling and pit is of course 'provided under thegrate, Ventilating may be eiected in Warm Weather. Resting upon the upper ends of the pipes the usual functions, and 11 refers to a door ing ilangesv or collars 30 and 31 whic enor giving access tovsaid pan. gage said' pipes 22 and 2A, respectively, the

I prefer to employ air-supply piping 12 collar 31 being preferably rather long to having a breach l@ extending iet@ @head1 proud@ a, S119 101111.22 efenvly @klug-Care of expansion and contraction of the inner pipe 24, in which connection, it may be stated that the drawing illustratessaid pipe when expanded to the maximum, whereas cooling and contraction of said pipe will of course cause it to lower somewhat from the plate 29. In order that the stay-bolts will not. interfere with unhampered expansion and contraction of the pipe 24 in a vertical direction. these bolts are preferably passed only through the outer pipe 22 andI have their inner ends slidably engaged with said pipe 2l.

The cap plate 29 supports a suitable chimney 32 which extends through the roof of the building and may well be formed of brick, although this is not essential, as any desired materials may be used. The pipe 24 is placed in rather restricted communication with the chimney by a discharge neck 33 .at the center of the plate 29, said neck extending upwardly into the chimney so that Athere is no possibility of the latter shifting laterally with respect to the remainder of the system.

By providing the novel construction shown and described, or a substantial equiv-` alent thereof, a system is provided which will utilize heat heretofore going to waste up the chimney or stack, and consequently great economy in fuel is effected, as well as obtaining moreheating eiciency. Moreover, the invention is readily convertible for use as cooling and Ventilating means in hot weather. Thus` with a single system two needs are elfectively overcome. y

As excellent results may be obtained from the general construction disclosed, it may well be followed. However,- within the scope of the invention as claimed, modifications may of coursey be madee I claim:

1-. A heating system comprising a furnace having spaced inner and outer walls and an air inlet into the space between said walls, means within the inner wall permitting heating thereof to in turn heat the air between the two walls, an outer pipe rising from the outer wall and adapted for passage through an opening or openings in the Hoor or floors of the building in which the system is used, an inner pipe' within said outer pipe in spaced relation. with the latter and rising rigidly from the aforesaid inner wall to form an exhaust gas escape therefrom, a cap plate resting on at least the outermost of said pipes and connected with both of said pipes,

and a chimney rising from and supported by said cap plate, said outer pipe having air escape openings.

2. A structure as specified in claim l; said chimney being formed as a separate part from said cap plate and the latter being provided with an upstanding discharge neck received in said chimney to hold the latter in proper relation with the plate.

3. A heating system comprising spaced inner and outer walls and an air inlet for the space between them, means within the inner wall permitting heating thereof to in turn heat the air between the two walls, a horizontal plate resting on the upper ends of said walls and having heat discharge openings betweenthem, collars rising from said plate adjacent said inner and outer walls, spaced inner and outer vertical pipes engaged with said inner and outer collars respectively and adapted for passage through an opening or openings in the floor or floors of a building, acap plate resting on the outermost of said pipes and having a restricted central opening, depending collars engaging the inner and outer pipes respectively, the center of said cap plate having an upstanding discharge neck surrounding said restricted opening, and a chimney supported by said cap plate, said neck fitting within said chimney, the outermost of said `pipes having hot air discharge openings.

4. A heating system comprising spaced inner and outer walls and an air inlet for the space between them, means within the inner wall permit-ting heating thereof toin turn heat the air between the two walls, a horizontal plate resting on'the upper ends of said walls and having heat discharge openings'between them, a downwardly extending flange on the outer edge of said plate and surrounding said outer wall, collarsrising from said plate adjacent said inner and outer walls, spaced inner and outer vertical pipes engaged with said inner and outer collars respectively and adapted for passage through an opening or openings in the floor or floors of a building, a cap plate resting on the outermost of said pipes and having a restricted central opening, depending collars on said plate engaging the inner and outer pipes respectively, the collar engaging said inner pipe being elongated and forming a slip joint connection with said inner pipe to permit the expansion and contraction of said pipe, an upstanding neck surrounding the restricted central opening in said cap plate, a chimney supported by said cap plate, said neck fitting within said chimney, stay bolts passed through said outer pipe and having their inner ends slidably engaged with said inner pipe whereby the latter is centered, but permited to expand and contract, and valved air conducting pipes connected with the space between` said outer and inner pipes.
