This invention relates to air-circulating and heating systems for buildings, and more particularly to an improved form of fin-typc extended surface radiator adapted to be locat-ed within the wall of a room.
One object of this invention is to provide a radiator stack having-a lower grille opening for drawing cold air from the bottom of the room and an upper grille opening for delivering heated air to the top thereof.
A further object is to provide a housing at the bottom of the stack for covering the front of the radiator, said housing having a lower grille opening located at an elevated position above the floor of the room for per mitting a broad stream of air to be drawn into the radiator stack.
A further object is to provide a housing at the lower part of the stack containing the lower grille opening, said grille being so positioned as to prevent air from entering the stack except through the fins of the radiator.
A further object is to provide an apparatus of the above nature which will be simple, a ter in construction, inexpensive to manufacture}.
easy to install and manipulate, compact, ornamental in appearance, and very efficient and durable in use.
, With these and other objects in View there has been illustrated on the accompanying drawings one form in which theinvention may be conveniently embodied in practice.
Fig. 1 represents a front view of the radiatoras it appears. when installed within a wall of a room. i i
Fig. 2 is a side sectional view of the same. Fig. 3 is a top view of the radiator unit. Fig. 4 is a front view of the same, the bottom header being shown partly in section. Fig. 5 is an end view of the radiator unit. Fig. 6 is a fragmentary sectional view showing one of the compression qouplings'for connecting the ends of the radiator tubes with a header. r
Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the radiator unit comprises a pair of upper and lower rectangular headers 10 and 11 of square cross-section connected together by two rows 1928. Serial No. 278,417.
of staggeredv tubes 12 and 13 res ectivel The tubes 12 and 13 are surrounded hy a pliizahpy of iiertigaflly-spaced horizontallv-exenc inginc me 'ns 13a referab I to said tubes 12 and 13. p 1y soldered In order to form a leak-proof detachable connectlon between the tubes and the'headers, t he ends 14 of the tubes are-adapted to ht Within annular seats 15 formed near the lower ends of socket openings 16 leading to thet ntegior 1710f tlhe headers, one such connec 1011 em 0 ear shown in F'". of the tube gids 14. is In 6 Each locked in its seat 15 by a compression coupling member 18 which is exteriorly threaded-and has a hexagonal wrench-engaging section 19 on one end and a tapered annular rim 20 on its other end. The coupling members 18 are adapted to be screwed into correspondingly threaded sections 21 of larger diameter than the tube seats 15, said threaded sections being oined to said seats by inclined convex shoulders 21a.
By means of this construction, when the coupling members 18 are screwed into the header socket openings 16, the annular rims 20 of said coupling members will enga e the inclined shoulders 21a and will be fore d inwardly against the exterior surface of the tubes, thereby forming a tight leakproof connection therewith. It i will be understood, however, that the tubes may be easily detached from the headers merely by rotating the coupling members 18 at the opposite ends of said tubes in the reverse direction from that just described. The headers 10 and 11 may then be separated relative to each other, whereupon the entire bank of tubes and fins may be removed for cleanin or other purposes. b In order to permit the headers to be read- 1ly cleaned, provision is madeof detachable countersunk closure site ends thereof.
The steam, hot water, orother heating medium is permitted to enter the radiator through an mlet pipe 25 located behind the tubes 12 and 13, said pipe 25 being conneeted by an elbow 26 to the upper header 10, whereby the heating medium will be plugs 23 in the oppo-' adapted to be securely caused to pass downwardly through the! tubes 12 and 13 and will leave the radiator unit at the bottom through an outlet pipe 27 connected to the lower header 11.
Provision is also made of a standard form" of radiator air valve 28 connected to the top of the lower header 11 for allowing air to escape but preventing loss of the heating medium from the radiator.
The radiator unit just described is. adapted to be located within a radiatorstack 29 positioned within the wall of a room, said stack extending upwardly from the floor 30 of said room and terminating in a top wall 31. The radiator stack 29 is preferably arranged within the framin studding, or chase in one of the walls 0 a room so that the front of the stack may be subsequently covered with lath or plaster to conceal said stack. a
A pivoted damper 32 is suspended from said top wall 31 and has an operating handle 33 whereby it may be swung about its pivot to re ate the flow of heated air to the room t rough an upper front opening 34 of the stack 29 and an upper ornamental grille member 35.
In order to support the radiator unit in position within the lower part of the stack 29, provision is made of a pair of bracket members 36 riveted or otherwise secured to the sides, of said stack. The lower front part of the stack 29 is left open at 37 for permitting the radiator unit to extend out somewhat into the room, and said radiator unit is adapted to be concealed by a housing 38 resting on the floor 30 and having its upper end curved inwardly at 39' to fit snugly against the portion 40 of the wall in front I of the stack 29, Intermediate its upper and lower ends the housing 38 has a forwardly extending rectangular lower grille section 41 which has an opening adjacent to and co-- inciding with the front vertical heating area of the bank of radiator fins, whereby all'of the air drawn from the bottom of the room without abrupt turns. Dead air spaces will thus be avoided, and due to the chimney draft effect of the high stack and the fact that the inclined fins are alinement with the natural course of the air circulation, the resistance to the 'flow will be minimized and the circulation of air in the room and the radiator system will be quite rapid, thereby producing uniformity of temperature throughout the room.
One advantage" of the present invention is that the heating unit occupies but little space within the room and owing to the attractive arrangement of the grilles adds considerably to the ornamental appearance thereof.
\ A further advantage of the present vertical construction of the radiator unit is that it utilizes only a small width of wall space in proportion to its heating capacity.
A still further advantage ofthe present invention is that thelower radiator housing is easily removable making the radiator unit quite accessible for cleaning or repairs.
While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit.- Inyshort, the invention includes all the modifications and embodiments coming within the scope ofthe following claim.
Having thus fully described the invention, what is claimed as new, and for which it is desired to secure Letters Patent, is:
'In an apparatus for heating and circulating the air in a room, a wall stack having upper and lower openings leading into said room, a grille covering said lower opening and having an ofi'set portion projecting forwardly into the room, a radiator located in said lower opening and havin fins extending into the offset portion 0 said grille, whereby the. air entering the stack through said lower opening will be efliciently heated as it passes over said radiator and its fins.
In testimony whereof, we have afiixed our signatures to this specification.
