Averill, Waterloo, Iowa, assignor to Titus Manufacturing Corporation, a corporation of Iowa Application October 30, 1956, Serial No. 619,306
' I 3 Claims. (CI. 98-40) This invention, in general, relates to diffuser mounting members for air distribution systems and to ceiling construction embodying the diffusers.
The mounting of diffusers of air distribution systems substantially flush with the ceiling has, in general, been a tirne-consuming,laborious project. This invention is concerned with devices and methods to facilitate the mounting of ceiling diffusers for air distribution systems. The ceilingdiffusers are mounted without cutting, trimming or patching of plaster. The old problem of centering the ceiling hole in alignment with the takeoff duct of the air distribution unit is eliminated. Further, the possibility of sagging of the diffuser away from the ceiling is eliminated.
' Itis, accordingly, an object of this invention to provide devices for mounting air diffusers in ceilings whereby the foregoing disadvantages are obviated.
It is a further object of this invention to provide means whereby the construction of ceilings having diffusers for air distribution systems is simplified.
A still further object is to provide improvements in methods for constructing ceilings having diffusers for air distribution systems. H In accordance with the invention, the diffusers are secured on the ceiling by means of a diffuser mounting member which is secured to the rigid ceiling construction members such as lathing channels, wooden ceiling beams, etc. The diffuser mounting member is connected at its rear portion with the air duct collar, or air takeoff member. The diffuser mounting member comprises, in addition to a rear neck portion for connection with the duct collar, a forwardly flaring portion preferably of a configuration and size similar to the rearmost air channeling member of the diffuser to be secured thereto. After the diffuser mounting member has been connected to the duct collar and secured to the rigid ceiling construction members, the lathing is. mounted on the ceiling after which the plaster is applied to the ceiling substantially flush with the outer rim of the diffuser mounting'member. The rim of the diffuser mounting member may have a lip extending rearwardly around the circumference. This lip is provided for lapping the plaster to provide secure grounding for the plaster and prevent chipping or cracking of the plaster around the diffuser assembly. After the plaster is applied the outer member of the. diffuser assembly is nested inside the diffuser mounting member and is securedto the member by screws or the like. I
The invention will be further understood in the light of. the following description in conjunction with the drawings, wherein: T
Fig. l is a perspective view of an embodiment of the ceiling construction of this invention;
' Fig.2 is a cross-sectional view of the ceiling construction taken along the plane 22 of Fig. 1, plus, in exploded relationship, a diametric cross-section of an air difiusing device;
Fig. 3 is a perspective viewof another embodiment of 14, mounted in telescopic relationship with the duct collar 12, comprises a neck portion 16 at the rearward end thereof, a forwardly flaring portion 18 and a peripheral portion 20 at the forward end thereof. The peripheral portion 20 terminates in a lip 22 extending rearwardly around the periphery of'the forward portion of the flaring walls. Diametrically opposed apertures 24 are located in the flaring portion 18 of the mounting member. The mounting member is rigidly secured to the ceiling construction members by metal screws 26 extending through the apertures 24. The ceiling construction illustrated comprises structural members 28 having cross members 30 mounted thereon by wires 32 or the like. The screws 26 extend into the cross members 30 to se cure in rigid fashion the diffuser mounting member 14 to the rigid ceiling structural members 28 and'30. Lathing 36 is mounted by suitable means along the ceiling surface. Plaster 38 is applied to the lathing members up to the lip 22 and laps the lip 22 to securely ground the plasteraround the mounting member.
The configuration of the flaring walls 18 of the mounting member 14 preferably is similar to the flaring walls 42 of theoutermost hollow member 40 of a diffuser to be mounted therein. By this construction the outermost member 40 can be nested in contact with the mounting member 14 whereby it is axially aligned with the duct collar 12. If the diffuser member comprises an outer member detachable from the inner deflection members as illustrated in the drawings, the outer member 40 may be secured in the mounting member 14 by means of metal screws extending through slotted aperture 46 into the mounting member. The slotted aperture 46 is provided to facilitate a snug fit. The terminal endof the finishing marginal portion 44 preferably is at least laterally coextensive with the peripheral portion of the mounting member. After the outer member 40 has been mounted in the mounting member 14 with the outer edge thereof in contact with the plaster 38, the inner series of deflection members 48, 50, which are rigidly or adjustably secured together by any suitable means, are connected to the outer mounting member 40 to provide the final assembled diffuser, a series of progressively smaller, hollow, flaring air deflection members spaced apart to define air channels therebetween. The means for mounting inner deflection members 48, 50 in the outer member 40 does not comprise a part of the instant invention and hence is not illustrated in the drawings. This means may be any construction enabling the mounting of the inner deflection members on the outermost member after the latter is assembled on the ceiling, such as the construction illustrated in U.S. Patent No. 2,229,747, issued January 28, 1941 or U.S. Patent No. 2,603,141, issued July 15, 1952.

In the embodimentillustrated the rigid ceilinglathing channels '28 are mountedib'e'lowgthe u duct 10. Cross bars 130 are secured by wires 32 to the V p for mounting said air diffuser member on ceiling con-f str'uction including an air distribution system which com-- prises: an open-ended, hollow member having a neck lathing channels and the ceiling mounting member-14 with the neck portion 16 in teles'cojpic relationship to the duct collar 12 is attached to the cr'ossmembers by screws 26. This structure provides a rigid mounting fp'fthe mounting member 140m the rigidstructural members'of the ceiling construction.

The ditfuser'member. isfthen .mounted in the mounting member -by the procedure heretofore described;
- In the embodiment of Fig. 3, the'diffuser mounting. member has a neck portion 60 and a forwardly 'flaring portion 62. Near the peripheryof the ditfusermountingl member theforwardly flaring portion .62 is's'haped'to' provide a .flat peripheralsurface '64 lying in a plane substantially perpendicular torthe axis .of the diffuser mount ing member. The walls of the diffuser mounting member extend forwardly at 66 and terminate in a flat marginal portion 68. The flat portion 64 is provided with diametrically opposed apertures 70 fora purpose .later described. In the embodimentshown in Fig.4 the .struc-' ture is essentially the same as that in Fig.- 3 and like. numerals have been used to designate like parts. The
embodiment of Fig. 4 differs from that of Fig. 3-in that it has a peripheral lip 72 similar to andfor the same purpose as the lip 22 of the embodiment shown. in Figs;

By this arrangement, the screw hole in. the member 73 is perpendicular to the lower-section thereof. Thereafter the ceiling is finished with the conventional lathing 36 and plaster 38. Theplaster 38 extends over the edge,
of the flat marginal portion 68 as shown in Fig.5. In the embodiment of Fig; 4 the plaster would be securely grounded over lip 72 in'a manner similar to t hat shown,
in Fig. 2. The diffuser then is mounted inthe diifuser mounting member in the manner previously described:
