The invention relates to an electric light intuire, and particularly that type of'lixture wherein a shade is used-Which may be ro-' fated vto cans-slight from the electriclamp to be reflected in any direction Whichmay be desired.

The electric light fixture is particularly adapted for use in anyy instance Where it is desired to shade the lainp and cause` the rays of lightgto ybe reflected ina` certain direction While being enabled" to rotate the shade to Vcausethe light= rays tobereflected in any other direction. Y

- vThe principal objectoffthe invention is to provideV a construction whichl is especially useiulin hospitalswhen a subdued f light is desired, 'and' not a fullflood of lig-ht from the'lanip. ln orderto rnake the ligygl'itfin-V conspicuous and-not disturb'the patient', or others, if the fixture is in the room,- or disturbany one if the fixture is-in ythe corridor, it is preferably placed about eighteeninches rfi-oni the-floor With-the shader in .position to causo the lightl raysto be reflected down-f wardly. In case any one' should*'desireA to use the light available. from the shaded lamp, as for instance, to examine instructions, a thermometer, etc., thek shade may bey rotated a half'turn andthe lightfvvill'thenbe lreflected' upwardly, or it maybe rotated. any aniount to cause the rays of light to be reflected Wherel desired,` n

The invention Will-be explained rand, ino-re clearly understood v whenl read. in conjunc tion with the accompanying"drawings which illustrate embodiments. of Whichzithe invention is susceptible, it being` obvious that changes an'dniodifi'cations in various details ofthe device rnay. beV made Without departing fro-inthe spirit` ofthe invention as eXf pressed in the appended claims-forming .a part hereof.

The structurey of the invention asshown in Figures 1, 2' and 3, comprises the relatively stationary'` supportingivall face plate 10,"the electric lanipand lampsocket re. ceptacle 11, and the'rotatable'annular aperf tured inner platev 12, to which' is secured the larnp shade or Ycowl 13;

rl`he supporting Wall yplate 10 may be square, asshown in Figure 1,-1nay `be circular, conforming -to the outline of the inner plate andshade, or, It may be rectangular,

andzrnay enibody1variousfeatures, such asv switches, sockets, connecting mechanism, and the like.A The lain-p socket receptacle 11*- is formed tof receive the supporting Wallplate 10, theV electric lamp socket, 14', the lamp socket collar v15,v andthe electric lainp or bulb 16.. Thea-socket, collar, andflanip may be ofrany construction adapted-.to be used Withthe fixture, and Will notbe further dcscribed.l Conductors 17l and v`18- for supplying? current to Athe`larnp, are shown extending .from the larnp: socket14. Y

The shade 13, Whichis preferably opaque, is permanentlyv and'securely fastened to the rotatable, annularv apertured inner plate 12. The shade is preferably riveted to the inner plate', since-the' shade 13 andfthe plate 12 always rotate-together. The shade 13`is shown rwith its lov'v'er portion 19 extending beyond the longitudinal central lineof the larnip 16 to `thereby,furnish more shader than would be the case if the lower edge of the shade 13 was in line with the longitudinal central line ofthe lamp16.- Although the sha'dell'has vbeen shown with theportion `19'extending.beyond-and below the horizoncentral line ofthe-lamp orV bulb 16. In seine.

instances it may be zulvantagcims, from a manufacturing standpoint', to forni an annular piece of metal into a cupped or dishedin portion and a suitable peripheral flange, and` then cut or saw the metal through its center and thereby produce two shades from the single piece of metal. ln this form of shade it is obvious that there will not be an extended portion, such as the extended portion 19, referred to. The rivets 2O extend through the flange 21 of the shade 13, and the outer portion of half of the apertured rotating' inner plate 12.

The lamp socket receptacle 11 is formed as shown, and is provided with the annular extension or guidinglip 22, which is formed to provide an annular shoulder 23. rllhe annular lamp socket receptacle 11, with the annular extension or guiding lip 22. and the shoulder 23, are permanently and fixedly secured to the face plate 10 by means of the bolts and nuts 24 and 25. As will be seen by reference tothe drawings, an annular groove 26 is formed by the assembly of the annular lamp socket receptacle 11 with the extension or guiding lip 22, the shoulder 23. and the supporting plate'10. The apertured plate 12, to which the shade is secured, rtates in the groove 26. Between the apertured plate 12 and the supporting` or wall face plate is interposed an annular apertured shim 27. The shim 27-may be se cured to the plate 1() in any desired manner, as by the flat headed rivets 23. One or more of these shims 27 may be interposed between the two plates 10 and 12, so that a proper fit may be obtained to enable the shade 13 to be rotated in its groove in a desirable manner. It is essential that there shall be a friction fit between the .movable and the relatively stationary members, so that the shade 13 may .remain in the position in which it is placed upon rotation until it is desired to move it to some other position. lt will be understood that it is the primary purpose of the invention to have the parts 'constructed in such a manner that the shade tion until it is moved therefrom. as, for instance, by grasping the shade 13 and rotating it to a changed position. It will thus be seen that the shade 13 may be rotated at will to cause the rays of light from the lamp 16 to be reflected downwardly or upwardly, or to either side,

1n connection with the finish of the supporting wall plate 10 there is difficulty in rotating` the shade 13 and the plate 12 if the wall plate 10 is finished with enamel, and it would be ditlicult, from a commercial standpoint, to enamel the plate 10 to the exact outer peripheral line of the plate 12. rThe whole of the outer surface of the plate 10 may be enameled, and the shim 27 can then be placed on the enameled plate 10, thus affording a proper surface against which the plate 12 may contact and rotate.

ln assembling the fixture the shadeI 13 is secured to the rotating apertured plate 12, as hereinbefore described. The lamp and socket receptacle 11 and the rotating` apertured plate 12 are then placed in position, as shown. The apertured face plate 10 is then brought into place against the receptacle 11, and is secured thereto by the bolts and nuts 24 and 25, or in any other suitable manner. The lamp socket, with its collar and the lamp or bulb, may be screwed into position in the aperture of the lamp and socket receptacle 11.

The light fixture as a single unit may now be mounted in any suitable' location on the wall, or as shown in the drawings, it may be mounted in a suitable receptacle or terminal box'29, which has been set in the wall.` The light fixture is fastened and secured to the` terminal box 29 by means of screws 30 and 31, which are countersunk in the plate 10, and extend through the inwardly extending` walls or sides of the ter minal box 29. As shown, the shim 27 has been perforated for the admission of the screws y30 and 31, and the aperturedistationary plate 10 has also been provided with holes for the admission of the screws 30 and 31. In order to place the screw 30 in posithe screw 30. The screw 30 may then bey put into place, and when this has been accomplished, the shade 13, and the apertured plate 12 may be rotated a half turn until the screw hole 32 registers with the screw hole in the bottom part of the supporting` wall plate 10 for the admission of the screw 31. The fixture is now ready for use, and the shade may be rotated in the manner set forth.

rlhe modified formof electric light lixture shown in Figures 4 and 5 comprises the relatively stationary combined supporting' wall face plate and electric lamp and lamp socket receptacle 33, the lamp shade or cowl 34C, with its flange 35. and the annular retaining' ring` 3G. rl`he plate and lamp socket receptacle 33 is formed to receive the electric lamp socket 37, the lamp socket collar 38, and the electric lamp or bulb 39, which latter are of usual construction.

The annular retair-,ingv ring' 36 is permanent' ly and securely fastened by means of rivets, or in any other suitable manner, to the combined face plate and lamp receptacle 33. rlhe electric lin-ht xture may be mounted in a suitable receptacle or terminal box 40,

set in the wall; 'Thefixture is'secured in the terminal box` 40 vby means offscrews41 and 42, which are countersunk in the coinbined face plate and; socket receptacle 33, and extendthrough the inwardly projecting walls or sides of the terminal` box 40. The

i shade 34 of Figure 4fisshown .withits` lower portion 43 extending beyond the longitudinal centralline of the lamp 39 to thereby furnish more shade, as described in connectionk with the shade of Figures 1,'2vand 3. As will be clearly seen from an inspection of'Figures 4 and 5., the lamp shade may be rotated to any position desired. Theshade is held 1oetween the 'face plate andl socket -receptacle 33 and the retaining ring 36 by having the shade 'flange 35 held in the groove formed by the'ringandplate It willbe noted that the retaining ring is formed in such a manner as to provide a slot or groove within which the flange of the shade may travel. friction fitbetween the movablev andthe relatively stationary members so that the shade 34 may remain in the positionin which it is placed upon rotation until it is desired to move it to some other position, as dcscribedin connect-ion with the operation of the lixtureshown in Figures l, 2 and 3,

In order to secure the fixture in the terrninal box 40, substantially-the saine procedure must be followed with-reference to the screws 41and 42, as was done with the screws 30 and 3l of the structure of Figures l, 2 and 3. In order to place the screw 4l in position the shade34, with its integral flange 35, must be rotated sufliciently to expose the screw hole in the upper inwardly extending lip of the terminal box 40. The screw 41 may then be placed in position, and when `this has been accomplished, the shade 34 may be returned to its normal'position, whereupon the screw 42 may be placed in position in the lower inwardly extending lip of the terminal box 40. It is necessary, of course, that the screw holes for the admission of the screw 4l in t-he combined face plate and socket receptacle 33, and the upper lip of the tcrminal box, be below the lower line of the retaining ring 36.

A further modification Vof the electric light fixture is shown in Figures 6 and 7. rIhre structure as shown in these figures comprises the relatively stationary supporting wall face plato 44, the electric lampand lamp socket receptacle 45, andthe rotatable annular apertured inner plate 53, to which is secured the lamp shade or .cowl 47. The supporting` wall face plate 44 is bent inwardly a sufficient distance to enable the lamp socket receptacle 45 vto be suitably secured to it. -The receptacle 45, which is cup-shaped, and adapted to fit Within It is essential that there shall be athe inwardly extending portion 1 of thel face` plate, has ears or lugs48 and49, punched therefrom. 'The supporting wall faceplate 44 and the. lamp` socket,y receptacle 45 are both apertured to receive the electric lamp, sockety50, the lampsocket collar 5l,and the electric lanipaor bulb 52.

The shade 47 is' permanently andsecurely of aA groove. for supporting the yrotatable annular apcrturcd-plate 53 .and permitting the plate 53 and the shade, 47 to `rotate about the electric lamp. I v

The plurality of bolts serve a purpose similarto the shoulder 23, shoWninIFigures 2fand3.v v l In assembling this form of xture the shade 47' is. secured to the rotatable apertured plate 53.k Thelamp socketfreceptacle 45 is then passed intothe aperture of the plate53'!with the annular; flange against the inner portion of the plate The bolts and nuts 56, 57, 53 and 59 arejthen placed in position. The wall plate 44 is next attached tothe ears 48 and 49 of the lamp socket receptacle 45 by means of the plurality of screws and 6l. The lamp socket, collar and lamp may be screwed into position in the apertures of the lamp socket Vreceptacle and the face plate. As thus" assembled the fixture may be mounted in the terminal box 62 set in the wall. The fixture is fastened to the terminal box 62 by means of screws 63 and 64 countersunk in the plate 44, and extend through the inwardly extending walls of the terminal `box 62. In order to placethe screw 63 in position the shadev 47, together with the apertured plate 53, is rotated a half turn until the screw hole 65 in the plate 53 registers with the screw hole in the upper part of the support-ing wall plate 44 for the admission of the screw 63. After the screw 63 has been put in place the shade and attached plate may be rotated a Vhalf turn until the screw hole 65 registers with the screw hole in the bottom part of the supporting Wall plate 44 for the admission of the screw 64. The fixture is now assembled ready for use and the shade may be rotated as desired.

In FiguresY 4, 5, 6 and 7 n.0 shims are shown, but it will be understood that shims of suitable form and dimension may be Cil employed between the rotatable and stationary members.
