Referring to the drawings, and more particularly to Figs. 1-4 thereof, the lighting fixture 10 formed according to the present invention is adapted for mounting in a wall or ceiling recess and comprises a housing 12 having lamp socket supporting means 14 secured therein. The housing i may be formed of any suitable material and in the preferred embodiment is formed of sheet metal and comprises a pair of laterally spaced side walls in and 18, and a pair of laterally spaced end walls and 22, said walls being preferably in integral relation. The housing 12 is further provided with a rear wall 24 which extends between the walls 16 and 18 and the walls 20 and 22 and is preferably in integral relation therewith. Thus the housing 12 is of quadrilateral formation although it is to be understood that said housing may have any desired configuration and may be formed in any desired manner. Thus the peripherally extending walls 16 and 18, 2t and 22 define the outer periphery cf said housing and the latter is adapted to be positioned in any suitable complementary dimensioned recess in a manner which will be described in' detail herein after. Each of the walls 16, 18, 20 and 22 is provided with an outwardly projecting longitudinally extending flange 26, the latter being adapted for the securement of the frame structure 28 to said housing. The housing frame structure 28, in the illustrated embodiment, is formed of wood and comprises four structurally identical frame sections 30 which may be secured together in any desired manner and which are secured to the peripherally extending flanges 26 through the intermediation of any suitable fastener elements, for example screws 32. Each of the sections 3% is a longitudinally etxending member having inclined ends which are secured to adjacent complementary inclined ends of adjacent sections 30, as

clearly shown in Figs. 1 and 2. The frame structure 28 is thus forwardly positioned relative to the housing 12, extending peripherally of said housing, and it will be noted that said frame structure overhangs the peripherally extending walls 16, 18, 20 and 22 asubstantial amount, as best shown in Figs. 3 and 4. The lamp socket supporting means 14 is conventional in all respects and is mounted in the housing 12 in a conventionalmanner. More particularly, the. socket supporting means 34 comprises a supporting shaft 34 which is mounted to the rear wall 24 of said housing, centrally thereof, by means of the spaced fastener elements-36. A suitable reflecting plate 38 is mounted in any desired manner to the rear wall 24 of housing 12 interiorly thereof and the fastener elements 36 which are threaded complementary to the shaft 34 are in abutting relation with the rear wall 24 and the refiector plate 38. The lamp socket supporting means 14 further comprises a bracket was,

larger than the housing 12 and is of a configuration complementary thereto, said housing being adap" supported by the ceiling C through the ie 'on of the housing securing means which will now be described in detail. Each of the laterally spaced side walls 16 and 18 are provided with a pair of laterally spaced slots 48 which extend axially inwardly of the housing lit to the rear wall 24 of said housing. The slots 43 at the rear wall 24 have a continuous portion 59 which extends laterally inwardly of said rear wall as best shown in Fig. 2, for a purpose which will be apparent from the description which follows. Each of the slots 43, having the continuous portion 5% extending laterally inwardly of the housing 12, are identically formed and comp nion pairs of such slots are adapted for association a companion angle bracket 52, the latter comprisin a mounting flange 54 and a projecting leg portion 56. noun lg flange 54 of each of the angle brackets 52 is provide with a pair of apertures 58 which are longitudinally spaced corresponding to the spacing of slots 48 on its associated side wall. Each of the angle brackets 52 is adapted for securement to its associated side wall by means of any suitable fastener elements which in the instant embodiment are screws 66. Thus each of the screws '60 extends through a companion slot 455 in the side walls and is received and extends through a companion aperture 58 for mounting the angle brackets 52 to the housing 12. It is to be noted that the screwheads of screws 60 are disposed so as to be accessible from within the housing 12, said disposition of the screwhcads being adapted for a purpose which will subsequently described. Thus the side walls 16 and 1.8 are each slotted position which is shown in solid lines in Fig. 3 to a retracted position which is shown in said figure in broken lines, said brackets in said secured position being secured to its companion side wall by means of the fastener elements 60. In the secured position of the angle brackets 52, the projecting leg portions 56 of said brackets project laterally outwardly of their companion side walls so as to be in surface-to-surface relation with marginal edge portions 62 of the ceiling C defined by the recess in said ceiling. Each of the angle brackets slidably movable to the retracted position indicated in broken lines in Fig. 3 by releasing or unscrewing screw 6d a sufficient amount whereby to permit the bracket to be slidably movable rearwardly and laterally of the housing 12 to said broken line position. By unscrewing screws 60 a sufficient amount the brackets 52 may be slidably moved rearwardly of the housing 12 and thereafter may be moved laterally inwardly of said housing whereby it will be apparent that the brackets 52 may be slidably moved to a retracted position in which the projecting leg portions 56 of said brackets lie inwardly of the plane of -saidhousiug along the continuous slot portions 50 whereby to provide for the retraction of each of the angle brackets 52 to a position lying within the projected area of the housing In practice, the ceiling recess 46 is dimensioned complementary to the housing 12 so as to provide a small amount of clearance 64, and to permit the insertion of the housing 12 in said recess the angle brackets 52 are slidably moved to the retracted position shown in broken lines in Fig. 3. As best shown in Figs. 2-5 there is disposed upwardly of ceiling C in the region of recess 6 pair of laterally spaced longitudinally extending joists or members 66 and the side walls 20 and 22 of the housing 12 are adapted to be positioned between such joists or members. Thus in the installation of Figs. 2-5 the members 66 are spaced apart a sufficient d st nce to permit the insertion therebetween of the housm 3 and, more particularly the side walls 20 and 22 thereof, and for securing said housing in the recess 46 the housing is moved axially inwardly of said recess so that the frame structure 28 is in abutting relation with the outer faces 71'} of the marginal edge portions 62 defined by the recess $6. With the frame structure 28 so positioned the angle brackets 52 are slidably moved to the secured position shown in solid lines in Fig. 3, said slideahle movement being possible by moving the fastener elements or screws 66 which are accessible from within the housing 32. Thus each of the angle brackets 52 is slidaby moved laterally outwardly along the slot portions 59 and is thereafter moved axially outwardly of said until the projecting leg portions 56 of said 5 are in abutting relation with the inner faces 72 of the marginal edge portions 62 of the ceiling recess. With the angle brackets 52 so positioned the screws 60 are tightened so as to firmly secure the angle brackets 52 to a companion side wall of housing 12. It is to be understood that when the fixture 12 is mounted in a ceiling recess the brackets 52 will be gravitationally urged into abutting relation with the marginal edge portions 62 of the ceiling recess when said brackets are in the secured position. The securing of the angle brackets 52. in the secured position as aforedescribed completes the mechanical installation of fixture 10 in the ceiling recess 46.

The side walls 20 and 22 of housing 12 are each further provided with a pair of elongated slots 74 which are adapted for the reception of fastener elements for mounting the fixture it} in a modified manner. With reference to Fig. 9, there is shown a modified form of fixture installation in which the slots 74 are utilized, said slots being adapted for the reception of screws 76 for the securement of the housing 12 to the support members 78. The members 78, only one of which is illustrated, may be structurally similar to the joists or members 66 and in this modified form of installation the housing 12 is positioned in the recess 46 and is maintained in such position by means of the screws 76 which are received in the members 73, it being noted that each of said screws is screwed into an aperture in member 78 from within the housing Thus in the modified form of installation illustrated in Fig. 9, the angle brackets 52 are not utilized at all and do not interfere with this installation in any manner, said installation being effected by means of the screws 76 which extend through the side wall slots 74 and are received in apertures 80 of support members 78.

With reference to figs. l0 and 11, there is shown a further modified form of fixture installation wherein the laterally spaced joists or members 82 are spaced apart a distance substantially greater than the distance corresponding to the length of the side walls 16 and 18. In this form of installation a pair of support members 84 are secured to the joists 32 in abutting relation with ceiling C and, more particularly, there is provided a pair of longitudinally extending support members 54 which are secured to the joists 82 in any desired manner and extend thercbetwcen, said members 84 being in abutting relation with the marginal edge portion 62 of ceiling C defined by the recess 46", which is formed similar to recesses 46 and 46 aforedescribed. The members 84 are adapted to cooperate with the angle brackets 52 for the support of the fixture it) in the ceiling recess 46", wherefore it will be apparent that said members 84 constitute supporting structure in said recess for the support of lighting fixture Ill. In this form of installation the angle brackets 52 cooperate with members 8,4 in the same manner as aforedescribed wherefore it will be apparent that such form of installation is identical with the installation illustrated in Figs. 1-4 except that the angle brackets 52 are in cooperative association with the members 84 instead of marginal edge portions of the ceiling proper as in the aforedescribed installation. Accordingly the installation of Figs. 10 and 11 for fixture 10 is performed in a substantially identical manner as aforedescribed with reference to Figs. 1-4 except that the brackets 52 are moved from a retracted position to a secured position in which the leg portions 56 of said brackets are in abutting relation with adjacent inner face portions of the members 84. Thus where the joists 82 are laterally spaced apart in a non-complementary fashion relative to the housing 12 it is merely necessary to affix said joists or members supporting structure, such as members 84, with the latter constituting the supporting structure adapted for cooperative association with the brackets 52 which are utilized for mounting the fixture in its associated wall or ceiling recess.

Secured to the rear wall 24 of housing 12 is a suitable channel member 86 which defines a passage 88 adapted for the reception therethrough of suitable conductors for electrically connecting the sockets 42 to a current source. The passage 85 of the channel member 86 communicates with the interior 91 of junction box 93, the latter being secured in any conventional manner to the side wall 18. It will be understood that suitable electrical conductors will extend from the sockets 42 to a source of current, said conductors extending through passage 88 into the interior 91 of the junction box 93. It will be understood that the junction box 93 may be positioned otherwise than as shown herein and that such junction box structure and the electrical connections between the socket 42 and a source of current is conventional in all respects.

Pursuant to another feature of the present invention, the lighting fixture 10 is provided with a plurality of reflectors 99 which are removably secured in housing 12 with either face thereof in light reflecting position. More particularly, each of the reflectors 90 is adapted for reversible mounting in the fixture l and comprises a flexible plate 92 having its opposite faces 94 and. 96 formed with different light absorbing or reflecting characteristics. Thus the opposite faces 9 and 96 of plate 92 may be differently colored or may be coated differently whereby they may have different light absorbing or reflecting characteristics. Each of the plates 92 is formed of a flexible and resilient sheet metal material and is adapted to be concavely flexed as shown in Figs. 3 and 4 for the mounting thereof in lighting fixture 16. One side of plate 92 is provided with a cutaway portion 98 and the opposite side of said plate is notched as indicated at 1%, said notch and said cutaway portion being adapted for purposes whichwill be apparent fromthe description which follows: in the illustrated embodiment the lighting fixture It) is provided with four such reflectors 9b which are adapted to be mounted in the housinglZ in a position to reflect light from the bulbs 44-. The reflectors 94), when secured in housing 12, form a continuous reflecting surface and if desired an opposite pair of said reflectors may be of greater longitudinal extent than the other opposite pair of reflectors whereby to provide for said continuous or uninterrupted reflecting surface. It will be apparent that during the mounting of the housing 12 in its associated recess the reflectors 90 will be detached from the housing wherefore to provide for accessibility to the fasteners 60. After the installation of housing 12 in its Fig. 4 or the modified form illustrated in Fig. 12.

'tion whereas the lens ill-l;

associated recess is completed, the reflectors will be mounted in position in housing 12 in a manner which will now be described. Each of the frame sections 30 of the frame structure 28 is provided with a longitudinally extending groove 102, said grooves being positioned adjacent to the plane of the walls which define the peripheral surface portion of the housing 12. The rear wall 24 of housing 12 is provided with tapped apertures 104 which areadapted for the reception of screws we, said screws being adapted to register with the notches of reflectors 9%) for securing said reflectors in position in the housing. in practice, the edge 168 of each of the reflectors 90 will be positioned in the longitudinally extending slot 102 of a companion frame section 30 and will be concavely flexed until notch 19% registers with a companion aperture 164 of wall 24 and when such registry occurs screws we will be secured in said tapped apertures to complete the securement of the reflector 9! in the housing. Each of the reflectors 90 is secured in the housing 12 in a similar manner wherefore it will be apparent that a tapped aperture 104 will be provided for each of said reflectors, said apertures being positioned so as to provide for the concave flexure of the reflectors, as illustrated in Figs. 3 and 4. Reflectors 9b in their relaxed condition are of flat planar form and are adapted to be flexed in opposite directions whereby to provide for the reversibility of said reflectors. Thus the reflectors 95) may be readily reversed by detaching said reflectors from their associated mounting means and reversing such reflectors, it being noted that such reflectors are secured in housing 12. in the same manner regardless of which of their faces are positioned in housing 12 in position to reflect light outwardly of fixture 10. As previously noted each of the reversible reflectors 96 may have its f ces formed with different light reflecting or absorbing characteristics whereby it will be apparent that a practically unlimited variety of different light reflecting combinations may be achieved. Thus the reflectors 9a) are adapted to be mounted in the housing 12 with either face 94 and 96 thereof in light reflecting position whereby fixture ill is adapted to selectively reflect light corresponding to the face of said reflector which is disposed in the housing in light reflecting position.

Fixture 10 is provided with lens structure lltl which is adapted for support relative to the housing 12 so as to define the substantially unimpeded light passage 112 between the periphery of said lens structure and the housing. The lens structure 116 comprises any suitable lens 114 which is framed and supported by the frame structure 116. The frame structure 116, which in the illustrated embodiment is formed of sheet metal, is peripherally continuous and is provided with a peripherally continuous flange 118 which is adapted to support the lens 114 at its marginal edges 115. The lens 114 is secured relative to its associated frame 136 by means of the angle brackets 124, each of said angle brackets having a. projecting leg portion 12s which is adapted to be bent over adjacent marginal edge portions of the lens 114 for securing the latter in position. The lens structure is conventional in all respects and may take any desired form, for example the form illustrated in The lens 114 as best shown in. Fig. 4 is of flat planar formaillustrated in Pig. l2 is of generally dished shape. ,Fuiithermore lens 11 is of the prismatic type and from the above it is to be understood that the lenses 3114 may be formed of any suitable material and may diffuse light in any desired manner, for example said lens may have any degreeof transparency, or may be translucent or opaque. The lens structure 110 is adapted for support relative to housing 12. in the aforedescribed manner through the intermedi ation of the lens supporting brackets 124 as shown in Fig. 7, it being noted that one of such brackets is adapted to be associated with each of the walls 16, 13,

20 and 22 of said housing for supporting the lens structure. Each of the brackets 124 comprises a flat metallic plate 126 having a bent-over portion 128 whichis suitably apertured as indicated at 130 for the reception of fasteners for mounting the brackets to the housing 12. Each of the brackets 124 is adapted to be secured to an associated housing wall by means of screws 132 and said brackets are provided with a supporting finger 134 which is adapted to engage with adiacent portions of flange 118 of frame 116. The edge 136 of each of the brackets 124 is formed complementary tothe tr: 1: structure 23 of the housing whereby to provide for a very neat and attractive installation for brackets 524. As noted above, each of the reflectors 90 is provided with a cutaway portion 93, said cutaway portion being adapted to provide the requisite degree of clearance for brackets 124 when the latter are secured to said housing. Thus the supporting fingers 134 of each of the brackets 124 extend laterally inwardly of the housing and marginal edge portions of the lens structure 110 are adapted to rest on the finger portions 134 and will be gravitationally urged into engaging relation with said fingers when said lens structure is supported by the brackets 324. Thus each of the brackets 124 is secured to the housing 12 in a position for supporting the lens structure 116 whereby an unimpeded light passage 212 is defined between the frame structure 28 and the light transmitting means, here constituted by the lens structure 11b. Thus the light transmitting means 110 is dimensioned so that its outer marginal edges define an area substantially smaller than the area defined by the inner marginal edges of the frame structure 28 whereby the brackets 12-1 support said light transmitting means relative to the housing 12 to provide for the unimpeded light passage 112.

As aforenoted the frame structure 28 is formed of wood in the illustrated embodiment, although it is to be understood that said frame structure may be formed of. any desired material and may be ornamented in any desired manner, for example the outer faces 29 of said frame structure may be provided with peripherally cxtending grooves 3-1 whereby to give to the fixture an aesthetically desirable appearance. With reference to Fi 4. the frame sections 3% have facing strips 143 positioned thereon, each of said facing strips being adapted for detachable sccurement to its companion frame sec tion 3t Thus each of: the facing strips 140 is formed complementary to a companion frame section 38 means are provided to provide for the detachable securemcnt of said strips to its companion frame section. Each of the cing strips 14% is provided with a longitudinally extending flange portion 142 which is adapted to mate with a complemer ary portion of its companion frame section, said flanges 142 having a longitudinally extendiug bent-in portion 1'44 which is adapted to snap engage with adjacent portions of its companion frame section. Thus the flange portions 142 having bent-in portions 1 are adapted to snap engage with the frame structure 23 to provide for the detachable securement of said facing "trips to said frame structure. When the facing strips ire attached to the frame sections 30 the latter will completely concealed from view whereby the appearance of the fixture may be selectively altered by detaching the facing strips from the frame structure. formed complementary to a companion frame .section 30 and will completely conceal the latter when attached thereto. in the preferred embodiment said facing strips are formed of sheet metal presenting an aesthetically desirable appearance, it being noted that said facing strips may be formed of any suitable material and may have their outer faces ornamented in any desired manner. From the above it will be apparent that the outer face portions of the facing strips 340 and the outer face portions of the frame sections 30 are of dissimilar ap- I US in practice, each of the facing strips 140 will be or I) peanance whereby the appearance of the fixture may be selectively. altered by detaching the facing strips from their companion frame sections in Fig. 9 the frame section 30 is shown without a companion facing strip positioned thereon whereas in Fig. 4 such frame section is shown having 21 facing strip 144) attached thereto.

In practice the housing 12 of the lighting fixture 10 :aforedescribed may be readily inserted in its complementary ceiling recess by tilting said housing a sufiicicnt amount to permit the insertion of junction box 93 through said recess.

While we have shown and described the preferred embodiment of my invention, it will be understood that various changes may be made in the present invention nithout departing from the underlying idea or principles of the invention within the scope of the appended claims.
