"iThis invention relate generally to air outlet devices for=ventilating systems, 'andhas particular reference to improvements means for mounting in thenecks of 'such devices" adjustable air deflecting units for use predetermining the pattern of the air deliveredfrom such devices. Generally speaking, the object of the invention isto provide simple, practical means to facilitate mounting ofan air deflecting unit in the neck of any air outletdevice and to'enable ready and easy removal of the unit from theneck whenever desired for cle aning, adjustment or any other purpose. y I

An adlustableair defle'ctingunit' of the t pe with whichtheipresent invention is concerned 'co mprises'a band or'ring and a plurality of vanes extending across the same and p'ivotedthereto for adjustments to desired air deflecting angles relative to the band or ring and relative to each other. In this connectiona more specific object of the invention is to provide in the neck of an air outlet device, mounting means for an adjust- .able air deflecting unit'of the type mentioned, which mounting means is in the form of-spring arms with which the ringorband ofthe air de- 7 fleeting unit may readily and easily be engaged to operatively mount said unit in said neck and from which said band or, ring-may readily and easilybe disengaged to permit removal of the air deflecting unit whenever desired. A well known type of air" outlet livering air from an air supply duct into a room or other enclosure for heating, cooling, ventilatingorother purposes compris s a plurality of sucessively smaller, open-ended, hollow, flaring members which are spaced apart successively inwardly of one'another and the larger or outermost'of which-is provided at its smaller or rear end'with a neckfor connection with an air supply du'ct;- "Thus, air supplied to-the device through the neck thereof is divided by the flaring members into a plurality of separate'streams which are deflected more or less laterally outward from the device, by said membersand the ,air thereby is delivered from the device in diffused form. In an air outlet device of this type it is known to connect together as a unitary assembla e all except the outermost ofthe flaring members and to provide means to mount 'saidunitary assemblage in the lar er or outermost flaring member for ready removal therefrom to afford ready access to the neck of the larger or outermost flaring member and thus facilitate connection of said neck with an air supply duct, as well as to fa l tate proper mounting of the-outlet device device for deas a whole.

aforementioned spring arms upon said unitary assemblage of flaring members so that when the latter is removed from the larger or outermost ,flaringmernber an air deflecting unit may readily and easily be engaged with said spring arms for subsequent operative positioning in the neck of the device by the mere act-of mounting said unitary assemblage in theiarger or outermost flaring member, and so that "in the event an air deflector is already engaged with saidarms when said unitary assemblage is removed, said air deflecting unit is removed with saidunitary assemblage and thereby is readily accessible for cleaning, adjustment, or any other purpose. Further in this connection, another object of the invention is to mount the said spring arms upon the struts or bars which usually are employed to connect together the flaring members of the unitary assemblage and to rem ovably mount said assemblage in the larger or outermost flaring member, whereby the said spring arms are firmly and securely mounted upon said unitary assemblage.

With the foregoing and other objects in View, as will become more fully apparent as the nature of the invention is better understood, the same consists in the provision of means for the purpose embodying the novel features of construction, combination and arrangement of parts as are illustrated by way of example in theaccompanyin drawings and as will be hereinafter more fully described and claimed.

'In the accompanying drawings, wherein like characters of reference denote corresponding partsint he different views:

' Fig.1 is a rear elevation of an air outlet de- .vice having 'operatively mounted in the neck thereof anair deflecting unit in accordance with the invention.

illustrating alternative constructions.

Refe r g to thie d wings in det il si e s, g ne al y. an a r Out d ic of a kn type with whichthe present invention is concerned and B designates,'generally, an air defleet n un t o a known typ f r use i n tion with an ,airoutlet device such-as the device A to predetermine the pattern of the air delivered therefrpm;

In this connection another object of the invention is to provide'for mounting of the v duct, and when air is supplied to the device through said neck it is divided by the members I0 into a plurality of separate streams which flow through the passageways II and are de- I,

flected more or less laterally outward from the device by said members ID depending upon the flare of the latter. The air thereby is delivered from the device in diffused form throughout a Y substantial area forwardly and laterally relative to the device. a v

The air deflector unit B comprises a ring or band I3 of a size and shape to be accommodated more or less freely within'the neck I2 of the outlet device A, an a plurality ofvanes I4 extending in suitably spaced apart,'preferablyfparallel relationship to each other, from side to side of said band and pivoted at their ends to said band, as indicated at I5, or rotative' adjustments to different angularpositions relative to each other. The air deflector unit B is designated to be mounted in-the neck I2 of the air outlet device A, in a plane at right angles to said neck, to position the vanes I4 s o that by proper pivotal ad- ,justments of the same they maybe caused to deflect supplied air through desired portions of the passageways and'thus predetermine the pattern of the air delivered from the device A.

In an air outlet device A of the type illustrated it is known to connect together as a unitary assemblage all except theoutermost of the flaring members I0 and to provide means to removably mount said unitary assemblage in the larger or outermost flaring member I0 to aflord ready access to the neck I2 for the purpose of facilitating connection of said neck with an air supply duct and proper mountingof the device A. In this connection and as illustrated by way of example in the drawings, all except the outermost of the flaring members ID are connected together as a unitary assemblage by a plurality of bars I 6 which extend across the smaller or rear ends of said members I0 and are welded or otherwise suitably fastened to said members: The outer 'end portions of said bars I6 extend beyond'the larger or outermost flaring member of the unitary assemblage and are bent to extend forwardly at angles corresponding to the flare of the larger or outermost flaring member ID of the device A so as to engage flatly against the front face of said larger or outermost flaring member to determine proper positioning of the unitaryassemblage of flaring members forwardly and rearwardly relative to said outermost flaring member Ill, More over, the terminal portions of the bars I 6 are bent to extend at substantially right angles to said bars in the planes of the outer end portions of said bars to provide said bars with hook-like extremities I1 for cooperation with suitable sockets I8 with which the larger or outermost flaring member ID of the device A is equipped to removably mount said unitary assemblage of flaring members in said larger or outermost flaring member II). The sockets I8 may be provided by U-shaped members I9 riveted, welded or otherwise suitably fastened against the front face of the larger or outermost flaring member ID of the device A, as illustrated in Figs. 1, 2, 3 and 5 of the drawings, or they may be provided by forwardly depressing portions 20 of the larger or outermost flaring member II] of the device A as illustrated in Fig. 4 of the drawings. In any event, it isapparent that the hook-like extremities .II and the sockets I8 provide means whereby the unitary assemblage of flaring members I0 may readily and easily be mounted in the larger or outermost flaring member ID of the device A and may equally as readily be disconnected from said larger or outermost flaring member of the device A for removal therefrom, simply by a small amount of rotation of said, unitary assemblage of flaring members relative, to the larger or outermost flaring member ID of the device A. The means for removably mounting the air deflecting unit B in the neck I 2 consists of a plurality of spring armsY2I which may, if desired, be permanently mounted said neck, but which, preferably, are carried by the unitary assemblage of flaringmembers whereby they are operatively positionedin therieckflIZ by mounting of the unitary assemblage of flaring members in. the larger or outermost flaring member of the device A and are removed from'said neck when said unitary assemblage of flaring .members is removed from the larger or outermost flaring member of the device A., I. a. j

If desired, the arms 2I.maybe welded, riveted or otherwise suitably fastened to one or more of the flaring members I0 of the unitary assemblage of said members; to the outermost of said members for example. Preferably, however, said arms are fastened to the bars I6, as thereby they are more firmly and securely supported than would be the case ifthey. were fastened directly to one or.more of the flaringemembers I 0. In any event, said arms extend rear'wardly from the unitary assemblage of flaringmembers whereby they are disposed in the neck. I2 and extend longitudinally thereof when theunitary assemblage of flaring members is operativelyfmounted in the larger or outermost flaring member ID of the device A. Moreover, said arms are positioned relative to the unitary assemblage of flaringmembers so that they are disposed more or less closely adjacent to the neck I2when 'saidunitaryassemblage of flaring members is operatively mounted in the larger or outermost flaring member of the device'A. In other words, the relationship of the arms 2| relative to each other is such that they are engageable with thering or band I3 of the air deflecting unitB at spaced points around said band to supportlthe latter'and, hence, said air deflecting unit B as an entiretyin its operative position in the neck I2 when the unitary assem blage of flaring members mounted in the larger or outermost flaring memberofthe device A.

To adapt the arms 2 I to hold the air deflecting unit against longitudinal movement relative to said arms, said i arms' are provided with ofi-set portions-22 wherein the ring or band I3 is accommodated and which afford'shoulders23 for engagement with opposite edges of saidrring or band. In this connection and as will be understood, the ring or band I3 may be disposed either outwardly or inwardly relative to the arms 2 I, and the portions 22 of said arms may be offset either inwardly or outwardly to accommodate said rin or band, dependingupon whether the latter is disposed outwardly or inwardly of said .arms. In any event, the arms 2I are flexible to enable ready and easy engagement and disengagement of the guide; the ring or band -;lfi onto said arm l3 with the aisle. and the (tre end rin or and 'edito portions; izlof' said armspreferably are ine'lf Fig. '14 illustrates thatfif' desires, the appeal! instead of the'bars fli, mayhave hook-like'porother'hand, Fig. illustrates that, if desired',.the

arms 2| may bepermanently fastened in and to the neck I2, in which connection it will be apparent that said arms may be either entirely separate from each other or may be carried by a ring or band as shown. 'As will also be apparent, the arms M may have their free end portions disposed either rearwardly, as shown, or forwardly if desired.

Whether the arms 2! are mounted permanently in the neck l2 or upon theunitary assemblage ofv flaring members, it is apparent that the air defleeting unit B is readily engageable with and disengageable from said arms when said unitary assemblage of flaring members is removed from the larger or outermost flaring member of the device A, whereby operative mounting of said air deflecting unit in the neck I 2 is greatly facilitated.

Spring fingers 26 fastened against the rear face of the larger or outermost flaring member In of the device A and having projections 21 to pass through holes in said larger or outermost flaring member into holes or depressions in the terminal portions of the bars IE or the arms 2|, as the case may be, are employed as a practical means of frictionally holding the unitary assemblage of flaring members against rotation in a direction to disconnect said assemblage from the larger or outermost flaring member of the device A.

From the foregoing description considered in connection with the accompanying drawings, it

is believed that the construction, operation and advantages of the means constituting the present invention will be clearly understood. It is desired to point out, however, that while only certain specific embodiments of the invention have been illustrated and described, the same is readily capable of specifically difierent embodimentsv within its spirit and scope as defined in the ap pended claims.
