(01; sic-516s) My inventionrelatestc immer/@merits in r diffusers for use in connection. with 11911 air 1.1. fr ing systems for circulating hot air forwheatlhg purposes or for circulating conditioned air in warm weather. v, l k, This air diffuser, while intended r.for general use in new installations, is especially ,welladapfted for use in remodeling to `take y,the placenof the conventional wallregister for ducts that are concealed entirely within the walls or to take the place of registers for dlt'sfpartly within the walls and partly inthe floor structure, or for use in prefabricated Abuildings where themwalls are too thin for duct` installations Vand hence the ducts must extend through the -floor structure.
The object of my air diffuser is to direct `air Yfrom a duct, leading froma hotair heating system, either forced or gravitytype, in all directions, so thatthis air. commin'gles withthe air in the room without vstrikingthe occupant or occupants inthe room, and `it valsodirects the air :away kfrom the respective walland the draperies :and other objects thereon. Y v
To the above end, generally stated, the invenftion consists ofthe Ynovel 'construction and arrangement of parts hereinafterfdescribed and dened in the claims.
In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings:
Fig. 1 is a front elevational view of the improved air diifuser;
Fig. 2 is a -sectional view taken on the line 2-2 of Fig. 6;
Fig. 3 is a top plan view of the invention and a fragmentary sectional View of the wall structure to which the air diluser is attached;

Fig. 5 is a fragmentary detail view in section taken on the line 5-5 of Fig. 1 and showing a closure for the respective air outlet;
Fig. 5a is a fragmentary detail view in section taken on the line lia- 5a of Fig. 6, on an enlarged scale, with the parts segregated;
Fig. 6 is a right side elevational View of the improved air diffuser;
Fig. 7 is a sectional View taken on the line I-'I of Fig. 3;
Fig. 8 is a fragmentary view of the adapter plate removed from the air diiuser; and
Fig. 9 is a fragmentary sectional view showing :a different arrangement of the air duct.
The numeral I0 indicates a stamped sheet metal housing having an` open back and bottom. This housing I!) isarectangular structure having in each of its side members a multiplicity of horizontal directional fins II cut and pressed therefrom. Thesens II extend into the housing It] and leave1 long horizontal rectangular air outlet passageways I2 therebetween. By reference to Fig. 2, it will be noted that the fins II are downwardly vinclined and direct air through the Ypassageways I2 downwardly toward vthe floor.
, CCI-operating with each series of hns II is a vplurality of upright directional blades I3 that are laterally spaced apart. These blades I3 extend .transversely of the fins II and are secured .tlreretqpt Atheirjoutertedges by welding. Said -blades i3 are transversely inclined to the planes of the side members of the housing Ill, and direct the air `in the passageway I2 outwardly into the room and away from Athe wall to which the air diffuser Ais attached.
In the 'top member of the housing I0 is `'a ypluralityof directional fins I4, similar to the fins H. These firis 'It are cut and pressed from the 'top vmember of the housing lil and leave rectangular air passageway's I5 therebetween. Said-mis rxt'endirito lthe housing It and are ."a'rrarig'il Vin tw'o rv`seri'esfariizl the fins I4 of these two series are reversely "inclined in diverging relation, see Fig. 2.
Co-operating with the fins I4 is a plurality of horizontal directional blades I6 that extend transversely of the fins I4. These blades I6, at the upper edges thereof, are secured to the ns I4 by welding. Said blades I6 extend transversely oblique to the fins I4 and are outwardly inclined to direct air in the passageways I5 outwardly into the room and toward opposite sides thereof.
An adapter plate II affords a back member and a bottom member for the housing II) cut out on the job, as indicated at I8, to receive an air outlet duct leading from a hot air heating furnace, not shown, as will presently appear. The housing II] and the back member of the adapter plate I1 are connected by folding the housing I0 at the inner side and top edge portions thereof to form a channel I9 and the corresponding edge portions of said back member are turned outwardly to aiord a flange 2l) that extends into said channel. The flange 20 is secured in the channel I9 by screws 2|, see Fig. 5a.
For the purpose of showing the air diffuser in working position, there is shown in the drawings a fragment of a wall structure comprising studs 3 22 and inner and outer walls 23 and a floor st1uc-A ture, indicated by the numeral 24.
An air duct 25 extends in part upwardly within the wall structure and part thereof extendsy through an aperture 25 in the floor structure 24..
The discharge end portion of the duct 25 ex tends through the aperture I8 in the adapter plate I'I and is folded outwardly over the adjacent edge portions of the adapter plate II, as` indicated at 21, t0 form a tight joint therewith..
rIhe inclination of the directional blades I3 and I6 may be varied, at will, by bending said blades at their attachment with the ns II and. I4. These adjustments of the blades I3 and I5, will, of course, be made at the time the air diffuser is installed, to efficiently distribute the air in the room in which the air diffuser is installed.
The adapter plate I? is attached to the wall against which it is placed by screws 28.' Said adapter plate I'I, at the edge portions of its bottom member, rests on an inturned flange 29 on the bottom of the housing I0.
The volume of air passing through the air diiuser may be controlled by a damper in the duct or dampers in the air diiuser, but for the purpose of this case it is not necessary to show the same.
On the inner side of each side member of the housing I0 is a rectangular frame 30 surrounding the respective air passageways I2. In case it is desirable to close the air passageways I2 in either side of the housing I() for any reason, for instance, if one side of the housing I0 is close to a wall, I provide a closure 3l for the frame 30. This closure 3 I as shown, is a plate having a capping ange 32 that its over either one of the frames 38. The frame 30 and capping flange 32 are indented at 33 to frictionally hold the closure 3l on the frame 3D, see Fig. 5.
In referring to the structure shown in Fig. 9, it will be noted that the duct 3A is on the outside of the face structure 23 and the adapter plate I'I completely closes the back of the housing I0.
The drawings illustrate a commercial form of the invention, but it will be understood that the same is capable of certain modifications, arrangement and combination of parts within the scope of the invention herein described and claimed.
What I claim is:
1. An air duct provided with an air diffuser including a main housing having side members, secondary housings on the inner faces of the .side members, said side members and secondary housings having air passageways leading from the interior of the main housing, horizontal directional ns in the passageways in the side members, and directional blades in the secondary housings extending transversely of the fins, the inner longitudinal edge portions of the directional blades being free and extending into the main housing, said blades being bendable to place the same entirely within the secondary housings, and cover plates for the air passageways in the secondary housings when the directional blades are entirely therein.
2. The combination with a wall and iioor hav- :lng a single aperture, an air duct back of the fwall and under the floor and extending into said aperture, said air duct having `an opening corresponding to the aperture and an endless flange overlapping the wall and oor at the aperture, of an adapter forming an extension of the flange, a housing attached to the adapter, and having side and top members, said duct being in communication with the housing, air passageways in said top and side members, and directional ns in said air passageways.
