JEHM K K 'f/IZ/N ATTORNEYS Patented June 29, 1937 PATENT OFFICE AIR DEFLECTING GRILLE John Karmazin, Huntington, Ind., assignor to General Motors Corporation, Dayton, Ohio, a
corporation of Delaware Application May 31, 1935, Serial No. 24,280
' Claims.
This invention relates to refrigerating apparatus and more particularly to a grille construction for use with an air delivery opening for conditioned air. It is customary in the air conditioning art and in other arts where air is circulated to and from an enclosure to provide grille means at the openings through which air passes from and to the enclosure for the purpose of defiecting the air stream, as well as to act as a guard for the opening and to lend a finished appearance to the structure.
It is an object of the present invention to provide a grille which will act to deflect air into a stream which is divergent in two directions.
It is a further object to provide a grille having two sets of fins arranged perpendicularly to one another, one of said sets being provided with spacing means to form a self-supporting grille structure and to form a support for the other set of fins.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing wherein a preferred form of the invention is clearly shown.
In the drawing:
Fig. 1 is a top view of a grille embodying one form of the present invention;
Fig. 2 is an end view of the grille illustrated in Fig. 1;
Fig. 3 is a fragmentary top view of a fin of the grille illustrated in Fig. 1;
Fig. 4 is a cross section on line 4-4 of Fig. 3;
Fig. 5 is a view corresponding to Fig. l illustrating a modified form of the invention;
Fig. 6 is a view corresponding to Fig. 2 showing the form of the invention illustrated in Fig. 5; and
Fig. 7 is a front view of a complete grille.
In the form of the invention illustrated in Figs. 1 to 4, there is provided a first set of fins I0 each of which is given a transverse curvature to deflect the air downwardly in Fig. 2, and is provided with a plurality of tapered tubular. projections I! to form a spacing means for the fins. This set of fins may be formed in the manner similar to that described in the copending application of Karmazin filed concurrently herewith and entitled Grille construction, Serial No.
24,279, filed May 31, 1935. Each of the fins is provided with a plurality of kerfs l 4 within which are mounted a second set of fins l6. The fins l6 are formed in the manner to deflect the air into a stream which is divergent toward either side of the opening within which the grille is mounted.
as may be seen from Fig. 1. The fins l6 are secured within the kerfs l4 preferably by a fused metallic bond which may be formed at the same time that the fins Ill and spacers I2 are bonded together although other means may be 5 utilized to secure the fins I8 to the fins ID. A boundary frame I8 is provided around the periphery of the grille structure for ease in mounting the same in a suitable opening.
In operation, air passing through the grille in 10 the direction from right to left in Fig. 2, is first deflected in a divergent direction from side to side by the fins l6 and before leaving the grille is deflected downwardly at an angle of about 45 by the fins ID. This construction is particularly 15 adapted for use in openings situated in a vertical wall above the level of the occupants of an enclosure to be air conditioned. In such an application, the grille described distributes the air in a fan-like stream from side to side of the 20 opening and projects this fan-like divergent stream downwardly toward the level of occupancy. Obviously, other fin arrangements may be utilized to provide for deflection toward any side of the grilled opening and with or without 25 tending to create a divergent stream.
In the form of the invention illustrated in Figs.
5 and 6, the fins 20 are similar in construction to the fins I0, except that the upper group of fins are formed fiat to direct the air straight through 3 the grille, the intermediate group are given a slight transverse curvature, and the lower group are given a more accented transverse curvature to provide for a divergent stream in the vertical plane, which diverges downwardly but not up- 35 wardly. The fins 22 are secured to fins 20 in a similar manner to the fins IS in Fig. 1, except that they are mounted upon the front face of the fins :20.
In operation of this form of the invention, the 40 air is first deflected into a downwardly diverging stream by the fins 2|] and thereafter is deflected toward either side of the grille opening by the fins 22.
While the form of embodiment of the present 45 invention as herein disclosed constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
What is claimed is as follows: 50
1. An air deflecting grille comprising in combination a unitary self-supporting set of parallel fins provided with spacing means therebetween, elongated kerfs on said fins, and a second set of fins transverse to said first set of fins inserted 55 3. An air deflecting grille comprising in combination a unitary self-supporting set 01' parallel fins provided with integral spacing means therebetween, and a second set of fins interlocked with and fused to said first named fins.
4. An article or manufacture comprising a plurality of parallel fins, spacing means integral with said fins, and a plurality of fins arranged a p rpendicularly to said first named fins and fused thereto.
5. An article oi manufacture comprisinga plurality of parallel fins, telescoping spacing means integral with said fins, and a plurality of fins arranged perpendicularly to said first named fins and fused thereto.
