In the embodiment of Pigures 4, 4a, 4b, and 5, the : reces-~ed light fixture 30 includes a modified receptacle 31, the : lateral wall of which has a smaller inward cylindrical portion 32and a larger outward cylindrical portion 33. The smaller and larger wall portions 32 and 33 cooperatively define an annular shoulder 34. An annular flange or rim 15 and a bottom 14 are provided as described in relation to the previous embodiment.
The porc~lain base ~ocket 16 and light bulb 17 are shown in dash lines.
A pair of clamping elements 35 are joined. to the re~eptacle 31 on diametrically-opposite sides thereof. It must `~ be appreciated that there may be provided more than two clamping ~;~ element3 35 and may be spaced at any convenient position around the receptacle. A hol~ is provided through the shoulder 34 at each of ~he selected positions for the clamping elements 35.
~ ~ach clomping element i~clude3 an iDward support portion 36 and a :~: clamping outward portion 37. An adjustment screw or bolt 38 ~ inwardly e~tends through each hole corrresponding to a clamping ;~ element 35 and e~tends through the support portion 36 of the latter to join the same to the receptacle. The holes for the bolts or screws 38 are oversize to allow relative pivoting of : each clamping element 35, as best seen in Figure 4b, for its passage through the aperture 19 upon insertion of the light fixture through that aperture.
It must be noted that this combination allows clamping to surroundinq coDseruction elementY or ~anels of di ff erent ~ `

thickne~e~. For instance, in Figure 4, the adjustment screw 38 i~ tightened until the clamping arm portion 37 holds against a relatively thinner panel 39 compared to Figure 4a where a relatively thicker panel 20 of dry wall and the decorative ring 25 must be accommodated.
Figures 6, 6a, 7, and 7a illustrate a third embodiment of a recessed light fixture 50 according to the present invention in which a still different receptacle 51 is used. The ~ide wall of this receptacle include.~ a smaller inward cylindrical portion 52 and a larger outward cylindrical portion 53 cooperatively forming an annular shoulder 54. The receptacle 51 is also provided with a bottom 14 and an annular flange or rim 15, as aforedescribed in relation with the receptacle 12.
A pair of clamping elements 55, in the ~orm of right angle brackets, are joined to the receptacle 51 on diametrically-opposite sides thereof. The clamping element 55 inclu~es a ~upport portion 56 and a clamping arm portion 57. The support portion 56 i~ formed with an elongated aperture 58 extending longitudinally thereof. The larger outward cylindrical portion 53 of the receptacle 51 is provided with an elongated aperture 59 longitudinally extending in the axial direction of the receptacle. Each clamping element 55 has its support port.ion 56 inwardly projecting through the corresponding aperture 59 and has it~ clamping arm or portion 57 outwardly projecting along the cylindrical wall portion 53. An adjustment screw 60 e~tends inwardl~ through the clongated aperture 58 of r corre~pDnding g 0~98~
clamping element 55 and is threaded through the shoulder 54 to adjustably join the clamping element to the receptacle. A spring 61, held in a recess 62, is engaged around each adjustment screw and abut~ against the corresponding clamping element 55 to outwardly bias the latter.
Figure 6 illu~trates how the c}amping element may be inwardly retracted and held to allow easy insertion of the light fixture into the aperture 19. The full inward retraction of the , : , ~- clamping element by it~ corresponding adjustment screw 60 produce ,-~
10 a clearance Y, as shown in Figure 6, between the outward end of , ', ;~ the clamping arm 57 and the inward face of the panel 20. This , allows to accommodate panels of different thicknesses. The '''' clamping elements S5 are clamped in place after outward ' ~
displacement thereof in the direction of the arrows 63 and 64 ,~ , , where they are retained under the bias of the springs 61.
Predetermined adju~tment~ are thus provided in the in-an-out direction and in the lateral direction, as indicated by the distances Y and X, respectivley. ~ ' -, ~` Figures 8, 8a, 9, and 10 illustrate a fourth embodiment 20 of a recessed light fixture 70 according to the present invention ,and including a receptacle 12, as aforedescribed in relation with ~,~ Figures 2 and 3. A pair of brackets 71 are fixedly attached against the external surface of the side wall 13 in diametrically-opposite position~ relative to it. A clamping element 72 i~ adjustably joined to each bracket 71 by an adjustment screw 73. Each clamping element 72 includes a support . ',, . ',:
' ';I
: 2~9~33~
portion formed with an elongated aperture 74 extending longitudinally of th~ clamping element. Each screw 73 extends through the elongated aperture 74 and is screwed in the corresponding bracket 71 to allow clamping adjustment of each clampi~g element 72 toward and away relative to the f}ange 15 to clamping the panel 15. I~ addition to the circular aperture 19 cut in the panel 20, there are provided a pair of cutouts 75, of appropriate 3ize and positions, to allow spaces for the passage of the brackets 71 and clamping element~ 72 upon insertion of the light fixture into the circular aperture. Each clamping element 72 includes a curved and flexible clamping arm or portion 76.
Before insertion of the light fixture 70, its clamping elements 72 must first be adjusted toward or away relative to the annular flange 15 in relation to the thicknesQ of the panel 15. This is done by slacking the scre~s 73 to slide the clamping eleme~t to the desired position, as allo~ed by the adjustment slot 74. The clamping element3 72 are tightened in position, such that its curved re3ilient portion 76 will deflect and exerts a clamping pressure against the panel 20 upon rotation of the light fixture 70, as shown by the arrows in Figure 8a, after full insertion of the same into its desired recessed position.
Figures 11 to 14 i}lustrate a fifth embodiment of a recessed light fixture 80, according to the present invention, and includes a receptacle 12, again as described herein above in relation with figures 2 - 3. The light fixture 80 is clamped in recessed po3ition in the aperture 19 of the ceiling panel 20, s , .

thanks to ~pring-loaded foot members, generally designated by 82.
Two ~uch opposite foo$ members 82 are shown, but more than two feet 82 could also be mounted to the receptacle 12 provided they are equidistant. Each foot member 82 includes a pair of ears 84, 86, integral to wall 13 and projecting outwardly therefrom in spaced register with each other, at a position intermediate rim 15 and base 14 of the receptacle 12. A bolt 88 is engageable through ears 84, 86 to be locked by nut 90.thereabout. A tapered rigid block or finger 92 having a transverse through-bore 94 at 0 it5 large end engages between ears 84 - 86 at its large end, wherein bolt 88 extends through bore 94 and ears B4 - 86 to permit pivotal motion of the finger 92 about the axis of bolt 94, that is, sub~tantially tangentially to the registering section of the wall 13. A notch 96 is made longitudinally of the large end lS of finger 92, and a sturdy coil spring 98 is engaged within that notch around the bolt 94. Coil spring 98 has two opposite, straight end -~ections 98a, 98b with .~ection 98a engaging a small tran~verse through bore 100 made in one leg 92a of the two legs formed by the finger 92 about notch 96.
Spring leg 98b will be made to abut against the receptacle wall 13 in a direction opposite rim 15. Spring 98 is biased to pivot finger 92 toward~ rim lS. Finger 92 preferably has a curved end 102 and must be longer than the distance bet~een rim 15 and bolt 94.
The two finger.~ 92 are manually pivoted away from rim 15 against wall 13 to the dotted line position of figure 11 in L98~
order that they clear ceiling aperture 19 to enable upward insertion of receptacle 12 through aperture 19 until finger ends 102 have moved past ceiling tile 20. Then fingers 92 will gradually pivot downwardly against the edge of aperture 19 during further insertion. When receptacle 12 is fully inserted, fingers 92 abut against the top face of ceiling 20 and are biased by springs 98 to move receptacle rim lS against the lower face of decorative ring 25. To remove the fixture 80, it is simply pulled downwardly so as to cause upward pivoting of fingers 92 10 and their clearing of aperture 19. -The curved free end 102 of each finger 92 is to form a convex surface for sliding on tile 20 during receptacle insertion.
It will be noted that all the embodiments of the invention enable clamping of the fi~ture to panel~ of different thicknesses.
The receptacle and the clamping elements are made of heat re3isting material. Preferably the material is moldable.

A tapered rigid block or finger 92 having a transverse through-bore 94 at 0 it5 large end engages between ears 84 - 86 at its large end, wherein bolt 88 extends through bore 94 and ears B4 - 86 to permit pivotal motion of the finger 92 about the axis of bolt 94, that is, sub~tantially tangentially to the registering section of the wall 13. A notch 96 is made longitudinally of the large end lS of finger 92, and a sturdy coil spring 98 is engaged within that notch around the bolt 94. Coil spring 98 has two opposite, straight end -~ections 98a, 98b with .~ection 98a engaging a small tran~verse through bore 100 made in one leg 92a of the two legs formed by the finger 92 about notch 96.
Spring leg 98b will be made to abut against the receptacle wall 13 in a direction opposite rim 15. Spring 98 is biased to pivot finger 92 toward~ rim lS. Finger 92 preferably has a curved end 102 and must be longer than the distance bet~een rim 15 and bolt 94.
The two finger.~ 92 are manually pivoted away from rim 15 against wall 13 to the dotted line position of figure 11 in L98~
order that they clear ceiling aperture 19 to enable upward insertion of receptacle 12 through aperture 19 until finger ends 102 have moved past ceiling tile 20. Then fingers 92 will gradually pivot downwardly against the edge of aperture 19 during further insertion. When receptacle 12 is fully inserted, fingers 92 abut against the top face of ceiling 20 and are biased by springs 98 to move receptacle rim lS against the lower face of decorative ring 25. To remove the fixture 80, it is simply pulled downwardly so as to cause upward pivoting of fingers 92 10 and their clearing of aperture 19. -The curved free end 102 of each finger 92 is to form a convex surface for sliding on tile 20 during receptacle insertion.
It will be noted that all the embodiments of the invention enable clamping of the fi~ture to panel~ of different thicknesses.
The receptacle and the clamping elements are made of heat re3isting material. Preferably the material is moldable.
