Definitions

  • This invention relates to air distributing devices for effecting diffused delivery of air from air supply ducts into rooms and other enclosures for heating, cooling, Ventilating or other purposes, and has particular reference to improvements in air distributing devices of the known general type comprising a plurality of successively smaller, open-ended, hollow, forwardly flaring mem bers which are disposed successively inwardly of and in spaced apart relationship to one another, whereby air delivered forwardly through the device is divided into a plurality of separate streams and is deflected more or less laterally from the device by said members so that the air is delivered into the room or other enclosure in diffused form over a substantial portion of the area thereof.
  • the flaring members may be of either frustro-conical form or of frustropyramidal form.
  • said members heretofore have been of frustro-pyramidal form they usually have had more or less sharply peaked ridges at their corners where the ends of their flat, inclined sides meet, and these ridges have had the effect of dividing the air which is delivered toward the corners of the devices and of deflecting it toward the adjacent sides of the devices.
  • the primary object of the present invention is to provide a device of the character referred to the flaring members of which are of square or other desired polygonal shape at their front ends and at least the rear, air deflecting faces of which develop gradually from square or other polygonal shape at their front ends to circular or substantially circular shape at their rear ends, whereby there are avoided any air deflecting ridges in said members and there is obtained practically as much flow of air from the corners of the devices as from the sides thereof so that the devices advantageously deliver practically equal 2 volumes of air in all directions laterally therefrom.
  • the shapes of the flaring members of the present device are generated by a straight line one end of which moves along the circumference of a circle and the other end of which moves along the perimeter of a rectangle, or other polygon, under conditions where the circle and the rectangle or other polygon are spaced apart and are axially alined with each other and are disposed at right angles to their common axis.
  • said members, or at least their rear, air deflecting surfaces gradually develop, as aforesaid, from square or other polygonal shape at their front ends to circular shape at their rear ends with the advantages stated.
  • Another special and important object of the invention is to provide a device of the character referred to wherein the aring members are of polygonal shape at their front ends, develop gradually to circular or substantially circular shape toward their rear ends, and have their rear end portions of frustro-conical or substantially frustro-conical form to initiate lateral deflection of the supplied air in all directions laterally from the device.
  • Fig. l is a rear elevation of an air distributing device constructed in accordance with the invention.
  • Fig. 2 isa .section on the line 2-2 of Fig. 1.
  • Fig. 3 is a front elevation of the device.
  • Fig. 4 is a section on the line 4--4 of Fig. 1.
  • the present air distributing device is of a known general type comprising a plurality of successively smaller open-ended, hollow members Il) which flare toward the'front end F of the device, taper toward the rear end R of ⁇ the device and which are disposed successivelyinwardly of and in spaced apart relationship to each other to provide a plurality of successively smaller, forwardly flaring air passageways Il therebetween.
  • a neck I2 extends rearwardly from the smaller or rear end of the larger or outermost .member I to adapt the device for connection with an air supply duct, and when air is supplied through said neck it is divided by the members le into a plurality of separate streams which flow forwardly through the passageways ll and are deflected laterally from the device by said ilaring members. The air thereby is delivered from the device in diffused form throughout a substantial area forwardly and laterally relative to the device.
  • the members I0 of which there may be as many as desired, may have equal or unequal amounts of flare, as desired, and their smaller or rear ends may be successively smaller so that they are disposed successively inwardly of one another, as shown, whereby air is delivered through each of the passageways Il.
  • the rear end of any of the members IB may, in accordance with known practice and as disclosed for example in Kurth Patent No.
  • each of the members l0 of the present device is of square or other desired polygonal shape at its front terminus Illa, has its front, straight edges ltlb disposed in a common plane extending preferably at right angles or in any event, transversely relative to the longitudinal axis a of the device, and is of circular or substantially circular shape at its rear terminus IUC.
  • each of said members l0, or at least its rear, air deflecting face Id is formed so that it develops gradually from square or other desired polygonal shape at the front terminus IGa of the member to circular or substantially circular shape toward the rear terminus of the member.
  • the rear portions i3 .of the present flaring members I0 are of :nostro-conical .or sab- Stantiallv nostro-conical form to initiate flow of the Supplied air in substantially equal amounts in all directions laterally through the passageways ll. If desired, however, any or all of said members l0 may be devoid of a frustro-conical or substantially frustro-conical rear portion.
  • any of the present flaring members has a frustro-conical or substantially fru'stro-conical rear portion
  • such portion preferably has the same amount of nare as the front portion of the member in a plane which includes the longitudinal axis a of the device and which extends midway between the ends of any two adjacent corners at the front end of the member.
  • the iront and rear portions o f the ilaring members may have any desired different amounts of flare.
  • any device constructed in accordance with the invention may include only. two members, the outermost of which may be of any suitable form and the innermost of which may be Aformed as described or the innermost of which may be of any suitable form to deflect air against the front face ille of the outermost member and the said front face of the latter member may be of the form described to deilect the air substantially uniformly in all directions forwardly and laterally outward from the device.
  • the present flaring member or members IG may be formed from sheet material or may be cast from any desired material and that, in either case, it is essential only that the air deilecting face or faces of said member or members, as the case may be, shall be formed as hereinbefore described.
  • the front ends of the members l0 may be disposed either in a common plane or in different planes, as desired, also, that the rear ends of said members l0 may likewise be disposed either in a common plane or in different planes, as desired.
  • the members l0 may be connected together in spaced apart relationship to each other by means of struts in accordance with known practice or in any other suitable manner.
  • all except the larger or outermost of said members are connected together as a unitary assemblage by arms I4 which have hook-like outer ends l5 engageable in and disengageable from suitable keepers I6 carried by the larger or outermost member l0 by slight rotation of said unitary assemblage relative to said larger or outermost member i 0.
  • the unitary assemblage of the member l0 may readily be removed from and mounted in the larger or outermost member to facilitate installation of the device in accordance with the general teaching of Kurth Patent No, 2,229,747 of January 28, 1941.
  • An air distributing device including a member having a rea-r face iiaring forwardly relative to the longitudinal axis of the device to effect lateral deilection of air delivered forwardly thereagainst, and means for directing air forwardly against the rear face of said member, the front edge of said member being of polygonal shape, the rear face of said member developing continuously and progressively from polygonal shape at its front end to substantially circular shape toward its rear end.
