ADJUSTABLE AIR DIFFUSER.
Application filed Kay 9, 1927. Serial No. 190,000.
This invention relates to air.difi'us'ersand has for one of its objects the provision of an air difiuser'capable of being secured in the wall of a room for directing the flow of air from a duct or flue into the room. 0
Another object is the provision of a diffuser having a plurality of blades capable of being adjusted to different positlons whereby the flow of air 'into the room may be controlled and directed to suit the convenience of the occupants of the room.
Still another object is to provide sufiicient space between the plates so as to allow for 'the'insertion of a persons hands w1th1n the casing for adjusting the plates.
With these and other objects in view, the invention resides in the novel features of "construction and combination and arrangement of parts as more fully hereinafter set 2 forth.
In the drawings: 1
. Figure '1 is a front elevationof my improved air difluser;
Figure 2 is a section taken on lines 22 of Figural; A I i .Figure 31s a section taken on line 3-3 of Figure 1; I a Figure fl is a detail view of the blade securing means; Figure 5 is another detail of the blade 'securin means showing the blade in several dotted line positions; I I
Figure ,6 is a detail of the seam joining the upper wall with one of the side walls. y In the accompanying drawings wherein like characters of reference indicate like parts, the numeral .1 designatesan adjustable air diffuser provided with an open casing 2, preferably of rectangular formation having the top and bottom walls 3- and);
'and side walls 5and 6 respectively. 1 h
As shown, the casing 1 is provided with a rear portion 7 and a front portion-B, the
As will be noted the side walls 5 and 6 lower walls 3 and 4 extend substantially,
adjustment may be effected.
the same distance on. the front side of the border as at the rear.
Positioned within the casing between the top and bottom walls 3 and 4 are a plurality .of spaced blades 10. As shown each blade v is secured at its front,end to a rod 11 pivotally mounted between the top and bottom walls at the front edges thereof, while to the rear end portion of each blade is pivotally secured a wire rod 12. The end portions of each rod 12 are extended horizontally to form upper and lower loop portions 13 designed to cooperate with screws 14 to form adjusting means for the blade. As shown the screws are secured to the upper and lower rear walls of the casing, each set being in substantial vertical alignment and adapted to project within the adjacent loop 13. Any suitable means such as the washers 15 and wing nuts 16 may be provided for clamping the blades in different positions of adj ustment.
Preferably my diflfuser is provided with an odd number of blades, the arrangement being such that there is a centrally located substantially. flat blade and an even number of curved blades on each side of the'central blade. As shown each set of curved blades are curved outwardly toward each side of the casing so that in the position shown in Figure 2 the arrangement is such that there will been even distribution of air issuing from the-diffuser. I- Iowever, if desired the central blade maybe adjusted to either of its dotted line positions and each of the other blades may also be moved about its pivot to difi'erent positions of adjustment so that an unlimited number of positions of As will be 'noted each casing wall is composed of a single sheet of metal joined at its ends to the adjacent end portions of each of the other walls. While any suitable locking means may be employed, 1 preferably form each end portion of the top and bottom walls with a vertically extending flange 17. Each end portion of the side walls is provided with a closed return bent portion 18 and an open return bent portion 19 extending therefrom and receiving one of the 105 vertical flanges 17 of the top and bottom walls. As shown each portion 19 securely retains the flange 17 in place and to provide a further securing means the portion 19 is prolaterally extending flanges projecting from the walls of the casing and joined at their ends to each adjacent end flange portion.
In the case of the side walls, the flanges 21 extend laterally from the extreme front end portions thereof and are provided withinwardly extending closed return bent portions 22 to strengthen the flanges and at the same time form smooth rounded edges. In order to provide the same finish and strengthening features, the top and bottom walls are provided with closed return bent portions intermediate their ends forming integral flanges 23 which also have the double thickness of metal and the rounded edge portions similar to the side flanges 21. Thus there is provided a strong simply constructed and finished border presenting a neat and pleasing appearance to the eye.
a In the installation of the diffuser the portion in the rear of the border 9 is secured in the wall opening 8 with the portion in frontof the border projecting from the wall 9. With this arrangement the adjustlng means for the blades are at the extreme rear of the casing. However, the blades are spaced 2. suflicient distance apart so as to allow for the insertion of a persons hands within the casing for manipulating the blade adjusting means. It will therefore be readily apparent that after each pair of nuts have been loosened, the blade lIl question may be placed between the hands and moved about its pivot to the desired position of adjustment.
lVhile it is believed that from the foregoing description the nature and advantage .of my invention will be readily understood,
I desire to have it understood, that I do not limit myself to the specific construction shown and described and that such changes mav be resorted to when desired as fall within the scopeof the claims.
What I claim as my invention: 1. In an air diffuser, the combination with a casing adapted to be supported in a wall opening, of a plurality of vertically disv posed blades uneven in number, pivotally mounted in said casing, the centrally disposed blade being entirely straight in formation and the blades on each side of the center blade being curved in the direction of the side of the casing nearest thereto, and means for retaining each blade in different positions of adjustment independently of the other blade.
2. In an air diffuser, the combination with a casing, of a blade carried thereby having one end portion pivotally mounted in said casing, a rod pivotally mounted inthe other end of the blade, loop portions pro ecting from the ends of the rod and means carried by said casing engaging'said loop portions for retaining said blade in different positions of adjustment.
3. In an air diffuser, the combination with an open casing, of a blade carried thereby having one end portion pivotally mounted between the top and bottom walls of the casing, a rod pivotall mounted in the other end of the blade, aligned loop portions projecting laterally. from the ends of the rod and formed integral therewith, and screw and nut members carried by the top and bottom casing walls and adapted to engage aid loop portions and clamp the blade in different positions of adjustment.
4. In an air diffuser, the combination with a casing, of a blade carried thereby having one end portion pivotally mounted in said casing, a rod pivotally mounted in the other end of the blade and having its end portions projecting laterally in close proximity to the top and bottom walls of the casing, and means carried by said casing walls and engaging the end portions of said rod for retaining said blade in different positions of adjustment.
5. In an air diffuser, thecombination with a casing adapted to be set into a wall and constituting an air duct, vertically spaced rods projecting laterally'from a wall of said casing, blades pivotally connected at one end thereof to said rods and extending across said wall, clamping means on said wall in substantially horizontal alignment with said rods, and elongated loops pivotally connected to said blades at the other ends thereof and held by said clamping means upon said wall, said loops being movable'in the arc of a circle about said clamping means by positioning said blades in various positions relative to said wall.
6. In an air diffuser, the combination with a casing constituting an air duct, of blades for controlling the flow of air through said casing, rods projecting laterally from a wall of said casing and constituting pivot means for said blades at one end thereof, clamping means including adjustable members on said wall, and elongated loops pivotally connected to said blades, receiving portions of said clamping members, and adaptedto be held by the latter in various positions of adjustment relative to said Wall, said loops being independently adjustable relative to each other and to said casing and clamping means when the latter is loosened for positioning said blades in various positions relat1ve to said wall, and thereby constituting manipulating means for said blades.
In testimony whereof I afiix my signature.
ROBERT M. HINRICH.
