AIR INTRODUCING DEV-ICE Filed Oct. 20, 1941 Patented Jan. 9, 1945 r 2 st ma e. was 20, 1941, Serial- Na 4 15.830
and john Evert fIn Sweden December 2, 1940 ingtoeffe'ct a proper distributiontoflttie airin L N the room and toavo-id-draught. f I v I, I V One object of thejinvention is to provide a an airiintroducing device simpleconstruction of e which can be easilymountedin-the opening of 1 an airconduit.
Q :nother object e theair introducing device; so as to enable various direction of the flow ofair within Widelimitsfby simple means. i
. A fu'rt er object of O l-1 invention ovide 9 a valve device in combination'with air s L and directing means.
With the foregoing and other objects view,
as' will appear as the description proceeds, our
invention residesin the combination and arrangement of parts and details of constructions described herein and particularly pointed out in the appended claims, it being understood that changes in the particular embodiment of our invention may be made within the scope of what is claimed without departing fromthe spirit of the invention. We intend no limitations other than those of the claims when fairly interpreted in the light of the full disclosure and the state of they art.
In the drawing: t Fig. 1 is a front elevation of the air introducing device according to one embodiment;
Fig. 2 is a central section on line A--A in Fig. 1, Fig. 3 is a rear elevation of the device according to a second embodiment,
Fig. 4is a central axial section. of the device illustrated in Fig. 3, and
Fig. 5 is a front elevation of the same device. In the drawing l designates an adjustable body provided with a central bore which forms the air discharge opening orpassa-ge of the device. At the outer periphery thereof said body is formed with spherical guide surfaces, and the body is supported on said surfaces, by means to be de-.
scribed hereinbelow, in such a manner that the longitudinal axis of the air passage may be set in any direction within a certain maximum angle.
of our invention is. to construct with the ai-r already preset in the room will be .fAlthough we prefer obtained thereby. M
helical vanesasimilar distrlbutiori effect may be obtained by; forming the.
vanestas planeplates set at an angle to the long'itudinalaxis of the discharge opening. Our;in-.
vention. is not limited to helical or planeoblique' vanes in apassage-having constant diameter but,
alternatively. may beof any spiral or combined spiral and helicalform ina passage the widthbf whichincreases in the directionof flow.
To enable the adjustment of the sphericalibody witha view to discharge the air invarious diree+ tiqns the body l is suspended between a fram d adapted to be attached to an air; conduit in any suitable manner and anouteryan nular flange 4f byyielding means such as three blade spring 5 which are attached and secured by screws 6 and engage .the sphericalsurface of thebod y "Ifhe annular flange ,4", has an inner diameter which,
' is smaller than the diameter of the spherical surface, and the springs 5 pressthe spherical body struction resides in the fact that the attaching towardsthe outer flange 4' So as to provide for tightening engagement between the spherical surface and the edge 4" of the opening of the outer flange 4'. i A particular advantage of the illustrated conframe 4 is the only element of the device which need be mounted in the building in question during the work, i. e. when the walls, the ceiling, etc.
are being made, whereas the more fragile parts of the device may be mounted afterwards and thus areexposed to injury during the constructionof the building. After the remainder ofthe building hasbeen completed, the valve body and the outerflange may be mounted. The three blade springs are applied simultaneously andare V In the air passage the body I carries a number spiral motion the velocityof which decreases in proportion to the distance from the opening of i the device. A rapid rmxture of the admitted air clamped between the flange and the frame for example'by screws 6.. The spring pressureactuating the spherical body causes thisbody to be maintained in place in itsadjusted position and simultaneously the springs allow adjustment of the body so as to enable introduction of the air in any direction within certain limits.
The deflecting vanes may have their ends securedto transverse wireswhich may cross each other such asthe wires 1 illustrated, and said wiresmay be clamped removablyin the opening ofthe body I. In this or other manner the guide vanes may be kept together to form a unit which may be easily removed in case of desiring a concentrated airflow ,towardsa certain place such as a work bench, a table or the like during particularly warm summer days. The invention of the passage in the body I may have provided therein helical notches for the ends of the wires so as to enable adjustment of the pitch or rise of the vanes by screwing the wires in or out at the outlet. mouth of the passage or vice versa so as to decrease or increase the distance between the vanes. The distribution of the admitted air' may be controlled by this means, and it is to be noted that in such arrangement the ends of the vanes may be pivoted on the wires.
In the embodiment illustrated in Figs. 3, 4 and 5, the device comprises valv means for control of the quantity of air admitted. Said valve means consist of two disks III, II which together are able to cover the area of the passage and have,
for example, a semicircular periphery and arespectively, secured to the body. One end of the spring thread engages one disk, and the other end thereof engages the other disk as shown in Fig. 3, and the spring may thus apply a shutting force to the disks if desired.
Y The disks II), II may be set in the desired position on the pin by a. hook I 8 or any other suitable operating means. On setting the disk or disks to the position corresponding to the air admission desired the disk maintains the position to which it has been set, due to the friction afforded by the friction washer.
As shown in Fig. 4 the vanes 2 extend only a part of the length of the air passage in the latr 2,366,778 also includes an embodiment in which the ends ter embodiment leaving the other part thereof free to the disks I 0, I I which may be set in a position substantially in the longitudinal axial plane of the passage (Fig. 4). In th fully open position the valve means offers very little resistance to the air flowing through the device.
What we claim is:
1. An air introducing device comprising an air directing body having an air passage therein and a spherical peripheral surface, air deflecting vanes in said passage for rotation of the air flowing therethrough, an annular flange surrounding the body and having smaller inner diameter than the outer diameter of said spherical surface, and
springs carried by said flange and engaging the spherical surface of the body to allow adjustment thereof and to force the body towards the flange to effect tightening engagement between the spherical surface and the flange.
2. An air introducing device comprising in combination with a frame for attachment to the mouth of an air conduit, an adjustable body mounted in said frame and having a-bore forming an air passage therein, springs attached to the frame and holding said body removably in said frame by engaging the periphery thereof frictionally so as to allow adjustment of the body to direct the air in various directions.
3. An air introducing device comprising a body having an air passagetherein, air deflecting vanes wholly within one'part of said passage for, rotation of the air flowing therethrough, valve means wholly'within another part of the passage for the control Of the air quantity admitted, a supporting structure and yieldable frictionmeans carried by said structure to holdthe body adjustablytherein so as to allow air to be discharged in various directions.
