. air and induce a maximum amount of secondary air with means to change the directional flow o the primaryair.
Another object of my invention is an air distributor which will take a small stream of primary air at either high temperature for heating or low temperature for cooling, and combine this stream of air with a maximum amount of secondary air for the purpose of moderating the temperature of the primary air and thereby avoid draft.
Another object of my invention is to combine the maximum induction of secondary air with means to change the 'flow of the combined stream to avoidwdrafts'.`
The `'foregoing and m'any other specific features of my invention are set forth in the following specification, where I describe what I consider the preferred embodiments of my invention. These are illustrated in the accompanying drawings where- Fig'ure 1 is an isometric view of the U-shaped member.
Figure 2 is a sectional view of Figure 3 taken on the lines 2-2 of Figure 3.
Figure 3 is a plan view of the diffuser.
Figure 4 is a sectional view taken on the lines 4-4 of Figure 5.
Figure 5 is a plan view of a diffuser.
Figure 6 is a sectional view of Figure 'I taken on the lines 6-6 of Figure 7.
Figure '7 is a plan view of a circular difiuser.
Figure 8 is a sectional view of Figure 9 taken on the lines 8-8 of Figure 9.
Figure 9 is a plan view of a cone-shape diffuser.
Figure 10 is a modification of Figure 9 showing the u-shaped members tilted for spiral discharge.
Referring to Figure 1, a U-shaped member Ill is shown comprising a closed portion II, fianges |2 and |3 extending laterally from the closed portion, with open ends |4 and l5 and a longitudinal opening |6 with lug attachment l'l. The longitudinal edges of the fianges l2 and |3 are designated by the numeral 21.
Figure -3 shows the U-shaped members in a grille effect with a frame IB which may be of any shape, having an opening 22 for the passage of air against the closed portions and past the lateral flanges [2 and |3 of the U-shaped members. w
Referring to Figure 2 which shows a sectional view of Fgure 3 taken on the lines 2-2 of Figure 3, the lugs I'l are attached to the side of the frame |8 which is attached to the duct 19 through which a stream-of primary air is forced by the fan 2| against the closed portions of the U-shaped members IO.
Figures 4 and 5 show a modification of my invention in which the U-shaped members Ill are attached to, the frame |8 and pivotally mounted on a pin 20 which is attached to the frame 18 so that the U-shaped members may be tilted from the normal, so that the air passing through is thereby diverted.
The induction of a large amount of secondary air is of great value in air conditioning when it is desirable to have the primary air at either relatively high or low temperatures to be then modified by the secondary air in the room which tends to avoid drafts and give good distribution.
Referring to Figure 6, there is shown a duct casing 29 with a fan 28 located in the duct, and outlet 30, in which outlet, are placed the U-shaped members IO spaced from each other as shown in Figure 7. It will be noted that the ends |4 and |5 of the U-shaped members are open to the atmosphere exterior of the duct.
Figure '7 shows a fiat circular diifuser in which the U-shaped members Ill are attached to the inner web 24 and the outer web 25. The difiuser is attached to a circular duct work shown in Figure 6 wherein the primary air enters through the opening 43, is forced through the duct work by the fan 28 and against a cone 36 and out the circular passage 30 so as to produce a stream of primary air in the form of a doughnut, and the passage of primary air past the U-shaped members lll will cause a flow of secondary air through the open ends |4 and 15 which are positioned outside of the stream of primary air.
Fgures 9 and 10 show a modification of my invention in which the U-shaped members l are attached to the inner lweb 24 and the outer web 25 to form a cone-shaped diffuser which is attached to the outlet of the duct work shown in Figure 8 in which the air entering at 31 is forced through the duct and past the diffuser by the fan 38 to the openings 39. The air is forced against the cone 40 so as to change the direction of the air into a circular stream. The open ends 14 and IB are positioned outside of the stream of the primary air.
The cone 40 may be adjusted towards the fan by means of the stem 4| which is a screw thread extending through the nut 42. In Figure 10, the members Ill are tilted from the normal so as to change the directional fioW of the primary air into a spiral. The direction of the fioW of the air in all cases is indi-cated by arrows. It W111 be noted that, in both Fgures 9 and 10, that the U-shaped members IB extend radially past webs 2-'3 and 25 so that their end openings M and are respectively open for the passage of secondary air either from outside Web 25 or under web- 24'.
I claim:
1. An air distributor comprising a duct having generally the shape of a frustum of a cone, a substantially circular baflie substantiall'y coaxial With said duct and spaced from the end thereof, said circular baffle and said duct defining a frusto conical opening therebetween, a plurality of longitudinal U-shaped members each having a Web portion with fianges extending laterally therefrom to provide a longitudinal opening and open ends, said U-shaped members being connected to said duct andV said ci-rcular baffie and lyin'g in radia'l planes across' said conicali'opening with their ends extending beyond the opening, za substantially conicaI baifle coaXi'aI with said duct and adjustably mounted on' said circular bafii'e.
2. An air ditributor comprising a duct havsubstantially conical baflle adjustably mounted on said substantially circular baffle.
3. An air distributor comprising a duct having a substantially circular open end, a bafiie member having generally the shape of a cone and positioned substantially at the center of said open end to form an annular opening With said duct, a plurality of longtudnal U-shaped members eachl having a'web porti'on andilaterally extending flange portions providing a longitudinal opening and open ends, means connecting said U-shaped members to said duct and to said baifie member with said U-shaped members positioned in substantially radial planes across said ann-ular opening With the ends of said U-shaped members extending beyond said annular opening, and' meansto force a stream of air through said annular opening and over said U-shaped. members'V Whereby air is drawn in through said open ends of said U-si'iaped members and out through the'l longit'udina'l'. openings' off saidi 'U- sh'aped members;
