  • Upper portions, 43 and 44 of the side walls22 and 24 respectively, are adapted to receive an :air turning vane assembly 40 which will be seen to extend upwardly into the duct 16 and as so located serves to turn the Ventilating air from its path ⁇ along the duct generally downwardly between the walls 22 and 24 of the device 10.
  • This assembly 40 will not be described in detail since it does not comprise an essential part of the present invention.
  • the air deiiecting flanges, 50 and S2 extend laterally inwardly from said lower side wall portions, 46 and 48 respectively.
  • the herein described device can be used with an exposed air supply duct of the type normally employed when the false or hung ceiling construction is not used. In such event, the anges, 56 and 58 might engage the periphery of the duct itself.
  • An elongated member 60 is supported in laterally spaced relation to the left hand side wall 22 and a lower portion 62 thereof defines a first air discharge slot 63 in conjunction with the air deiiecting flange 50.
  • a second air discharge slot 65 is dened adjacent said first slot and is symmetrically arranged with respect to said rst slot in 'the FIG. l embodiment.
  • the means defining said second slot comprises the lower portion 62 of said member 60 which is spaced from the lower portion 52 of said right hand side wall 24.
  • the elongated member 60 is releasably retained in a slot 64 provided therefor in each stay 28.
  • a spring clip 66 retained in each slot 64 serves to retain the member 60 therein and to urge the same against one side of the slot, in which position the rner'nber 60 is centered with respect to the side walls, 22 Iand 24.
  • the lower portion 62 Yof member 60 provides symmetrically arranged passageways which are directed angularly toward one ⁇ another for a purpose to be discussed hereinbelow.
  • the lower portion 62 of the elongated member 60 is symmetrical about a vertical plane passing through its center and defines outwardly and upwardly extending leg portions 68, 68 which define one side of the said passageways as aforesaid.
  • Each of these leg portions 68 defines a socket 70 in the upper end thereof for pivotally supporting an elongated v-ane 72.
  • Each vane 7?. is pivotally supported in its associated socket 70 for movement between open and closed positions whereby the iiow of air out of each of said slots and through said passageways can be independently varied with predictable effect upon the pattern and volume of air discharged from the device.
  • both slots can be opened, with one slot being opened more or less than the other depending upon whether the pattern of discharged air is to be deflected angularly downwardly between the vertical and horizontal toward the left or the right.
  • the air discharged from the slots can be directed vertically ldownwardly by simply positioning the vanes 72, 72 in a symmetrical fashion with each slot having a similar size opening and a similar shaped passageway.
  • the right hand component of velocity imparted to the air emanating from the left h-and slot will cancel the left hand component of velocity imparted to the air emanating from the right hand slot with the net result that only the vertical component of velocity will survive and the resulting air pattern will be one in which the air moves generally downwardly into the space to be ventilated.
  • various degrees of opening or closing of these vanes will also produce corresponding increases or decreases in the volume of air passing through the device so that these vanes not only permit the direction of the discharged air to be controlled but also the quantity thereof.

  • a series of stays 82 are spaced at intervals along the device 76 in the same manner as the stays 28, 28 described above.
  • the stays 82, 82 are of approximately twice the width of the stays 28,l 28 and define three slots 84, 84 one of which is centered therein for a purpose to be discussed.
  • the other two slots 84, 84' are similar to the slot 64 in stay 28 and support two vane supporting members 60, 60 which are identical to those described hereinabove with reference to FIG. 1.
  • Two pairs of vanes 72, 72 are pivotally supported in the lower portions 62, 62 of the members 60, 60 and these are manually movable from below the device 76 by a suitable tool (not shown) which is engageable with the barblike protrusion 74 provided therefor on each of said vanes 72, 72.
