Application filed January 3, 1928. Serial No. 244,191.
vided with means for supplying the radiator with air lto be heated, either fromI the door of the room or from an outside source.
A furtherfobject is to provide a heating apparatus of the above naturey having a casing located below the floor ofthe room, said casing including an upper angular frame having wall and floor grilles forpermitting the passage of air therethrough.
A. further object is to provide an improved form of damper mechanism, adapted to be manipulated from the floor of the room, for l shutting off the floor grille and opening communication with lan outside source of cold fresh air. y l
A further object is to provide a'device of this nature which will be simple in construetion, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance, and very eflieient and durable in use.
With these and other objects in view there .has been illustrated .on the accompanying drawings one form in which `the invention may be convenient-ly embodied in practice.
Fig. 1 represents a frontview of the radiator.
Fig. 2 is aside view of the same shown partly in section.
Fig. 3 is a sectional View on a somewhat smaller scale of the heating apparatus showing the arrangement of the radiator within the casing below the floor of a room.
Fig. 4 is a perspective View of the angular grille member. i' y Y Referring now to the drawingsl in which like reference numerals denote corresponding parts throughout the several views, the radiator unit comprises a pair of upper and low-er elongated rectangular headers 10 and 11 connected by a plurality of vertical tubes 12, seven in number in this instance. The
tubes 12are arranged in two parallel rows ink staggered'rela-tion and have their extremities threaded for engaging 1n threaded apertures in the headers 10 and 11. The tubes 12 are held in place by means ofnuts 13 which are screwed up against said headers. The tubes are provided with a plurality of parallel iny clined ns 14, soldered or otherwise secured thereto, said fnsbeing adapted to provide a i high rate of heat transfer from the radiator unit to the airv passing through it.
In order to'supply heat to the radiator, A
provision is made of afstealn or hot water inlet pipe 16 connected tothe top header 10, and the spent heating fluid is adapted to be conducted away through an outlet pipe 15 connected to the bottom header 11. Provision is also made of a standard radiatorair valve 17 located in the to'p header 10, for allowing air toescape, but preventing loss of steam or hot water.
kThe radiator unit'just described is located in al recess 18 formed within a wall 18al of the building just below the floor of the'room, and said radiator unit is adapted to be supported on a shelf 19 extending rearwardly from a vertical casing section 19a which is in alinement with the inner surface of said wall 18a.
In order to form a passageway 20 for conducting cold air from kthe door of the room, provision is made of a forward vertical casing section 21 which is arranged parallel to the vertical casing section 19a, whereby air will be drawn down through the floor of thel room andv caused to pass under the shelf 19fand be delivered through a damper opening 22 to a point below and behind the radiator unit. n
`The air inlet passage20, the radiator recess 18, and the stack 22a are closed by an angular member 22?) consisting of an integral floor grille 23, having openings 23a for permitting cold air to be drawn down through the floor, and a wall grille 24 having open- `permitting cold air to be drawn from out of doors, through a passage 26 connecting with the radiator recess 18. In order to permit the air inlet from the floor grille 23 to be closed, and the outside air inlet through the passage 26 to be opened, provision is made of a damper 27 hinged in the wall 18a at a pointadj acent said passage26. The damper 27 .is adapted to be manipulated v'by means of a damper-control rod 28 which extends up through the floor grille member 23, said damper-control rod -being connected at its lower end to-onearm of a bell-crank lever 29 fulcrumed at 30 to the supporting shelf 19. The other arm of the bell-crank lever 29 is connected by a link 31 to a rod 32 connected to said damper 27 the motion of the damper 27 being further guided by a rod 33 pivoted -in the bottom corner ofthe inlet passage 20 and connected to the joint .between ithe .link 31 `and .the rod 32. The-damper-control rod v28 is preferably vmounted Airi'ctionally in the floorjgrille23 so that :the damper 27 may be maintained in either-of itseXtreme positions .or -,in any intermedia-te position, according as fto whether it isdesired to deliver to the radiator coldair -rom thefbottom of the Aroom being heated, voutside air, 'or a mixtureof both. Y
For the purpose of-shutting off .the flow of warm air lfrom the .radiator through the stack 22a and into .the room, a handle-operated damper 34..-V is providedfsaid damper 34 being controlled vby a rhandle 35, extending through Y a slot 36 inthe wallgrillemember 241.
. In Voperation, .assuming that the damper `rod 28 ihas -been pushed -vvay1 down as .far as it will go so vthatthe Vdamper `27 is closed, cold air from the floor of the room will passdown through fthe -iioor .grille openings 23a, the .passage'20,-up through .the ldamper opening 22, into the radiator .recess 18, through the radiator :fins 14, up through the 'stach 22a, and out through the wall grille 2f1-intothe room again. When it isvdesired to deliver freshoutside airto the radiator, the operator will pull the damper rod 28 up as` far as it willV go, thus causing the damper .27 .to close `the .opening 2 2 .and open .the 'passage .26. When the damper rod 28 ris adjusted in any intermediate position, the air supplied `to vthe vtion on :the wall -of the room .as was thecase yradiator will be a mixture of 4room air and -outside a1r,-.the relative proportions of each depending on the position of'the damper`27. AThedirection ofthe air .flowl is shownby the arrows in Fig. 3.
It'will be understood that whilethe radiator unit ishereinfdisclosed as located `within arecessof a walllfthecasingof said radiator may be .locatedadjacent or away 'fromsaid wall within the spirit'and scope of said invention. l
One advantage :ofthe .present invention is that the radiator occupies nospace whatever with former so-called concealed radiators.
While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this formis shownfor the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but ymay be modified and embodied in various 'and vdamper-controlling means extending up .through the yHoor into an accessible position.
y2. In an apparatus for heating a room, Ya
.radiatorlocated below the floor of said room withina recess in the wall ofthe building, a
. damper for interchangeably supplying said .chamber located at the junction of the wall and .floor below `the lever of the floor, means for supporting a `radiator within said. chamber, said chamber having al passage below said' floor for-conducting cold airA from said room to said radiator, land an angular memberclosing the .top of said chamber and hav- -ing Igrille openings for allowing the passage ofcold air down from the room to said radiator, and of hot air from said radiator into said room.
'4. In an apparatus for .heatinga room, a chamber located at the junction of the wall and floor below Vthe level of the floor, means `for supporting a radiator within said chamber, said chamber having a passage below said floor for conducting cold air from lsaid room to said radiator, andan angular member .closing the top of 'said chamber, said angular member having a `horizontal y grille provided with openin s to Vpermit the passage ofcold air from t e room to said radiator.
5. In an apparatus for heating a room, a chamberlocated at the junction of the wall and floor of said room `below the level of .the floor, means for supporting aA radiator within said chamber, said chamber having' a passage below said oor for conducting cold top of said chamber and having grille openings for allowing the passage of cold air down from the room to said radiator, and of hot air from said radiator into said room.
In testimony whereof, We have aXed our signatures to this specification.
