DIRECTING DEVICE FOR USE IN VENTILATING OR OTHER AIR SUPPLY SYSTEMS England Application January 24, 1934, Serial No. 708,100 In Great Britain January 25, 1933 3 Claims.
This invention has-reference to air directing devices for use in ventilating or other air supply systems and to such devices of the kind by means of which the air can be directed in any desired direction within a portion of a sphere.
One known air directing device of the kind referred to comprises a bearing ring mounted with capability of rotation about its axis and a nozzle mounted in said bearing ring with capability of angular adjustment about an axis at right angles to the axis of the ring.
The main object of the present invention is to provide an improved construction or arrangement of air directing device of the kind referred to. Further objects of the invention are to provide means for diffusing the air issuing from the device and means for enabling the delivery from the device of ordinary atmosphere, heated or cooled air or mixtures thereof.
An air directing device in accordance with the invention comprises a member of hollow cylindrical or frustro-conical form or of domed shape or more or less hemispherical form 'with a hole to constitute an outlet, said member being divided along a plane inclined to its axis to form a base part which is mounted in a suitable support with capability of rotation about its axis and a nozzle part which is mounted on the base part with capability of rotation in, or about an axis normal to the plane of said division. The nozzle part may be provided with a valve or baffie which can be retracted into the part to allow the air to issue from the outlet in a straight path, or be moved into the outlet to practically close same-and cut off the air, or be projected from the outlet so that the issuing air impinges against it and is diffused. The support in which the base part is mounted may itself be mounted at the mouth of a ventilating duct, which communicates with supply ducts one for the supply of ordinary air and the other for the supply of heated or cooled air, or one for the supply of heated air and the other for the supply of cooled air, and a valve may be provided by the adjustment of which air from either supply duct or a mixture of air from the two supply ducts may be delivered by the device.
My combined angular adjustment of the two parts of the device, the air issuing from the nozzle part may be directed in any direction throughout a portion of a sphere depending upon the angle of the plane of division to the axis of the device. If such angle be 45 the direction may be any angle within a complete hemisphere, while if the angle be less than 45 the range of direction will be proportionately less than a hemisphere.
The valve or baflle may be provided with a spindle or stem slidably or otherwise adjustably mounted in a boss in a spider carried by the 5 nozzle part, the spindle or stem being adapted to co-act with a yieldable holding device to hold the valve or baffle in desired positions. Alternatively, the spindle or stem and the boss may be screw threaded and the valve or baffle be adjusted by rotating the spindle or stem.
In the accompanying drawings Fig. 1 is a front view or elevation of one embodiment of the invention, Fig. 2 is a section at right angles to Fig. l and Fig. 3 is a similar view to Fig. 2 showing the nozzle part rotated through an angle of 180 from the position in which it is shown in Figs. 1 and 2. Fig. 4 is a front View or elevation of another embodiment of the invention, Fig. 5 is a section at right angles to Fig. 4 and Fig. 6 is a section on the line VL-VI in Fig. 5.
On the drawings and in the following description like numerals of reference indicate like parts.
Referring first to Figs. 1, 2 and 3 of the drawings, l is a ventilating duct at the delivery end of which is mounted a hollow dome-like memher which is divided along a plane oblique to its axis and to the axis of the duct 1 to form a base part 8 and a nozzle part 9. The base part 8 is formed with a flange I0 which is rotatably engaged in a corresponding recess formed in a base ring H. The flange I0 is retained in engagement with the recess in the base ring II by means of a retaining ring l2, secured to the ring II by rivets l3. The base ring II and the retaining ring l2 are secured to the flange M of the duct 1 by screws I5.
The nozzle part 9 is mounted in the base part 8 so as to rotate about an axis normal to the plane of division between the two parts. Conveniently, the nozzle part 9 is formed with a spigot l6 which fits the opening in the part 8 and has secured to it by screws I1 a retaining ring l8 which engages behind a lip l9 around the opening in the part B. The nozzle part 9 is also formed with a hole to constitute an outlet 20.
It will be manifest that by appropriate angular adjustment of the base part 8 in the base ring I l, and of the nozzle part 9 relatively to the base part 8, the outlet 20 can be adjusted to direct the 60 inssuing air in any desired direction throughout a portion of a sphere depending upon the obliquity of the plane of division between the parts 8 and 9. In Fig. 2 the outlet 20 is shown in axial alignment with the base part 8 while in Fig. 3 it is shown directed downwards to the maximum angle. By rotating the base part 8 through from the position shown in Fig. 3 the outlet 20 will be directed upward to the maximum angle. By intermediate adjustments of the parts 8 and 9 the outlet 20 will be directed in intermediate directions and at intermediate angles. Fingerpieces 8 and 9 are provided on the parts 8 and 9,
respectively, for effecting their angular adjustments.
The nozzle part 9 has formed or provided inside it a bracket 2| in which is slidably mounted a spindle 22 at the outer end of which is mounted a valve or bafile 23 adapted to fit the outlet 20, and at the inner end of which is provided a stop 24. The valve or baflie 23 is provided with a fingerpiece 25 by means of which it and the spindle 22 can be drawn outward or pushed inwards. When the valve or bafile 23 is in its middle position as shown in Figs. 2 and 3 it closes the outlet 20 and no air or practically no air issues from the device. When the valve or baflle is drawn outwards, as shown in dot-and-dash lines in Fig. 2, the air issuing from the outlet 20 of the nozzle part 9 impinges against the valve or battle and is thereby spread or diffused. When the valve or bafile is pushed inwards, as also shown in dot-and-dash lines in Fig. 2, the air issues from the outlet 20 in a straight path.
For retaining the valve or bafile 23 in desired adjusted positions there is mounted in a recess formed in the bracket 2| a spring-pressed ball 26 adapted to co-act with a groove 21 in the spindle 22 to prevent rotation thereof, and to yieldingly snap into recesses 28, 29, 30 to retain the spindle and the valve or baffle 23 in the desired position.
In the embodiment of the invention illustrated in Figs. 4, 5 and 6 the duct 1 communicates with a chamber 3| into which open two ducts 32 and 33. One of these ducts may serve for the supply of ordinary atmospheric air from outside and the other may serve for the supply of either heated or cooled air, or one duct may serve for the supply of heated air and the other for the supply of cooled air. The ducts 32 and 33 are controlled by means of a valve 34 mounted on a spindle 35 which extends through the base ring II and is provided with a finger-piece 36 by means of which it has to be manipulated to completely close one of the ducts and open the other or to partly open both ducts as shown in Fig. 6, and so allow air from only one of the ducts or a mixture of air from the two ducts to be delivered by the device.
What we claim as our invention and desire to secure by Letters Patent is:
1. An air-directing device for use in conjunction with an air duct, comprising a frame adapted to be mounted coaxially with the air duct, a hollow base rotatably mounted in the frame for rotation about the axis thereof, a nozzle rotatably mounted in the base for rotation about an axis oblique to the axis of rotation of the base, and a valve slidably mounted along the axis of rotation of the nozzle.
