Patented Aug. 14, 1945 UNITED STATES PATENT OFFICE DISCHARGE OUTLET ,Ered- Albert Cull, Beaumont, Tex. Application March 18 1944, Serial No. 527,020 7 Claims. (Cl. 98-40) This invention relates to discharge outlets useful in connection with air distributing trunks of forced ventilation systems and the like, and has reference more particularly to outlets capable of adjustment relative to the trunks for directional discharge of the air.
In connection with discharge outlets of the kind referred to I aim to insure against looseness in the swivel connections with a view toward preventing rattling or vibration, and at the same time precluding air leakage.
Further aims of my invention are to facilitate flow of the air from the trunks into and through the discharge outlets, and to make possible regulatable diffusion of the discharge, as may be desired or required.
How the foregoing desiderata may be realized in practice will appear from the following description of the attached drawings, wherein Fig. 1 is a perspective view of an air conducting trunk of a forced ventilation system with a swiveled discharge outlet conveniently embodying my invention.
Fig. 2 is a view like Fig. 1 showing the outlet adjusted to a different position.
Fig, 3 is an inverted plan view of the organization shown in Fig. 1.
Fig. 4 is a side elevation of the organization. Fig. 5 shows the organization in end elevation: and
Fig. 6 is a longitudinal sectional view of the organization with the discharge outlet adjusted in the direction of the trunk.
As herein exemplified, the trunk I 0, which may be of sheet metal, is of oblong. cross sectional configuration, and has a circular egress orifice I l in' its bottom wall l2 toward which air forced under pressure through the trunk is directed by a plurality of spaced curved transversely-arranged bafiles l3.
The discharge outlet with which my invention is more especially concerned is comprehensively designated in the drawings by the numeral l4. As best shown in Figs. 5 and 6, the outlet is fashioned to the general form of an elbow with 2. laterally-open enlarged flaring portion or head I5 of quadrangular cross section, and with a somewhat narrower cylindric intake or neck portion l6 whereof the internal diameter corresponds to the diameter of the orifice H in the wall [2 of the trunk Ill. At the top, the neck portion I6 is formed with a laterally-projecting circumferenorifice I l of the trunk 10, I have provided a swivel joint structure including a bearing annulus IQ of rigid material on which the flange ll of th neck I6 is rotatively supported. As shown, the annulus I9 is circumferentially apertured for passage of the shanks of headed retaining screws 20 which serve as the securing means, said shanks threadedly engaging into the trunk wall'and to nuts 2| soldered 0r welded to the latter as conventionally indicated at 22. Interposed between the rigid annulus l9 and the trunk wall [2 is a compressible gasket means 23 which may be a washer of rubber or the like and of a size to extend around the periphery of the flange I! of the outlet [4. As shown, the gasket or washer 23 is apertured like the annulus 19 for passage of the shanks of the securing screws 20. As a consequence of this construction, it will be seen that by drawing upon the screws 20, the gasket 23 can be compressed to define with the annulus 19 a swivel bearing groove in which the flange ll of the outlet I4 is snugly retained with avoidance of any looseness such as would be likely to result in rattling or vibration under the action of the air flow through the outlet. In addition, the gasket 23 provides a seal to prevent air leakage around the joint, which by adjustment of the screws can be re-tightened in the event of wear.
Disposed within the open end of the head l5 of the outlet I4 is a register which is generally designated by the numeral 25 and which may be of any approved commercially available type with transversely-arranged pivoted shutter vanes 26, regulatable by means of a lever indicated at 30. The face plate 21 of the register 25 is marginally secured by means of screw bolts 28 to an inward- 1y extending perimetric flange 29 at the open end of the head I5. The curved crosswise bafiles 3| within the head I5 serve to direct the air, deflected downward from the trunk III by the baffles l3, laterally for discharge through th open end of said head as indicated by the arrows in Fig. 6v By turning the outlet I4 about its swivel connection with the trunk ID to d-ifierent positions as suggested in Figs. 1 and 2, the discharge can obviously be directionally controlled as desired, with attendant control of diffusion by regulating the louvers 26 of the register 25.
Having thus described my invention, I claim: 1. A. discharge device for air conducting trunks of forced ventilation systems and the like, having an elbow casing with a circumferential flange at its inlet end; and a swivel joint structure for connecting the casing to a wall of the trunk over an egress orifice in said wall, said joint structure including a retaining annulus surrounding the inlet end of the casing :behind the flange to form a bearing for said flange, a resilient annular gasket interposed between the bearing annulus and the trunk Wall beyond the peripheral edge of the flange, and regulatable securing means for drawing the bearing annulus toward the trunk wall to compress the gasket so as to preclude looseness in the joint and at the same time render it air tight.
2. The invention according to claim 1, wherein the trunk is provided with bafile means for directing the air through the orifice, and wherein the head of the outlet is provided with transversely arranged bafiles to direct the air through the discharge end of the casing.
3. The invention according to claim 1, wherein V the casing is provided at its discharge end with adjustable flow-regulating louver means.
4. The invention according to claim 1, wherein the trunk is provided with bafile means for directing the air through the orifice; wherein the head of the outlet is provided with transversely arranged baflle means for directing the air through the discharge end of the casing; and wherein said casing is provided at its discharge end with adjustable louver means with transversely extending vanes for controlling air flow from the device.
5. A discharge device for air conducting trunks of forced ventilation systems and the like, having a casing with an elbow portion of square cross sectional configuration and a cylindrical inlet neck portion with a circumferential flange; and a swivel joint structure for connecting the device to a wall of the trunk over an outlet orifice in said wall, said joint structure including a retaining annulus surrounding said neck portion behind the flange to form a bearing for said flange, a resilient annular gasket interposed between the bearing annulus and the trunk wall beyond the peripheral edge of said flange, and regulatable securing means fordrawing the bearin annulus toward the trunk wall so as to compress the gasket to preclude looseness in the joint and at the same time render it air tight.
6. The invention according to claim 5, including bafile means within the trunk for directing the air toward the orifice; and transverse bafiles for directing the air through the discharge end of the elbow.
7. The invention according to claim 5, including baflle means within the trunk for directing the
