iBe it. knjown that I, GUsrAv HAnrnR, citizen 'of .the United States, residingat Chi- `Illinois, have invented certain new andusefulImprovements in Electric-Light Fix# tures,.fof which lthe -following .is aspecification. v f

:'Thisinventionrelate's to electric fixtures,

. and more particularly to Ithe .mountingvand manipulation-of the shades and. globes and .the adjustment of the electric lampl support :with respect to the other parts. The principal Lobject of the invention is a provision of' an improved construction, combination .and arrangement by means of whichthe adjustment may be carried out.

In the accompanying drawings, "Figure -1 isaview partly in section and `partly broken away illustrating la construction which embodies the lprincipalv features of my invention; Fig. V2 is a sectional detail of the globe locking mechanism; Fig. 3 i's a side'elevation ofthe part shown in Fig. 2; Fig. 4 isa plan view of the socket-adjusting mechanisml.; Fig. 5 y'is a side velevationof-the socketadjusting mechanism; Fig.- 6 is a sectional .view taken on the kline A-A of Fig. 1; Fig. 7 is Va .plan view of `a modified form of socket-,adjusting mechanism; Fig. 8 is a side elevation `of the same; Fig. 9 is a view :o'f the end of the socket-adjusting mechanism; Fig. -10 is ,a sectional view vof a modified form of globe locking mechanism; Fig. 1 1 is a detail of the lock proper shown by Fig. 10; and Figs. 12 and 13 are plan and elevation ,views respectively of thescreen protector clamping ring. Y Y .v

In order to .provide .an electric lamp fixturecertain provisions must be made` for accommodating both the old form of electric lampswith carbon filaments land also fthe newer nitrogen lamps, as well as for the different sizes of lamps of `either kind. It is a welllknown fact that lamps must be raised or `lowered with respect -to their shades, globes `and reflectors in' .order to produce 'the best lighting effects, and in-order to produce various lighting effects.

.In v*the npresent' exemplifcation of Emy invention a housing or holder 5 is supported in any suitable manner, as for eXample,'by being threaded on the extremity of a pipe or conduit 6, and is preferably constructed of sheet or cast metal with a projecting flange 7 lat 'the top which partiallyzcovers lsocket downward.

Qn-wthe; inside lthisvhousing or holderis formed with., parallel ridges 9V spaced apart to4 form `a guide-wayv forythe .slotted ex- Yy tremities. -10 of a socket holder 11. )This l i threaded through ,a nut O13 whichsubstan-y tially fills the -guidefway and prevents the nut from' 'turning :so that the lsocket .holder may lbe readily heldin any adjusted. posi-v tion in 'which it is placed; ,Y i,

, VThis socket holder 111s designed'and intended "to fsupport -zsockets ofl various sizes.

` In .thezsocket 14, shown by Figs. 1,4 and.5,

are recesses ,15 at the top'the'reof for the reception of a nut 16. '.Terminals 17 andlS are also provided at the; top of the socket for lconnection with theordinary Velectric conductors. The socket holder 11 is formed j with ran upwardly extendingV yoke 19 vof sufficient width .tol allow. the socket, 14 to slidefreely therein the sides of the socket being .formed with grooves 14a for the yoke so that it may be adjusted atcvarious heights with respect to the yoke.y Theupright sides l of 'thejyoke are formed with slots20 (see Fig5) with an enlargement 21' at .the bottom anda screw 22 iSv-inserted through the slot and through a suitable 'hole in thebody of thogsocket14 into the nut lateach side of .the socket. y.rllhese'screws 22 may beadyjusted to hold a socket at any desired height with respect tothe yoke, and the 'enlarged opening' 21 at thel bottom of the yoke enables .one-toremove the socket fromtheI yoke without 'removing the screws22 vfrom the socket, .by `simply loosening them and sliding the If it is l desired to secureasmaller'sockety ,j to thesocket-holder 11y a pair .of socket 7 clamping 'members 23,'as shown `in Figs. '7 and 8, may be employed. These members 23have bent extremities 24 which'engage over thesides of the yoke portion v19 .and are held together by means of fastening devices 25. A socket 26 is inserted between them and by adjustingA the fastening devices 25 this socket maybe adjusted and held zin any position with -respect'to the yoke, kthe members 23 being slidable with respect 'tothe yoke and the socket 26 itself being slidable with respect to the `members 23.

.Atthe bottom of the holder 5 is a shade or .reflector ,27 which is l,preferably secured This shade preferably has anV upwardly eX- tending portion 33 which extends within the holder' at the bottom, and the object of the hinge above described is to prevent the I shade from hitting van lelectric lamp 34, in-

serted in the socket when the shade is rvtated about its hinge 'for any purpose. A globe 35 is usually inserted within the shade and in vthe'present invention it is held in place by means of one or more i'ixedsupports 36 projecting from the inside of the n shade and by means of a locking member 37 preferably pivoted at the same place as the latch 32 of the shade latching device and extends through a suitable aperture 38 of the shade (see Fig. This member 37 will remain in place as longas the upward projecting portion e3 of the shade is within the holder 5. As soon as this side of the shade is rotated downwardly so that the locking member 37 is freefro'm contact with the end of the holder 5 this member 37 may be rotated outwardly about its pivot through the aperture 38 soA that the globe 35 may be removed from the shade as desired. The lower end of the globe 35 is preferably provided with an aperture 39 through which air may enter, and through which dirt and the like will fall, the air escaping through the apertures 8 so that the circulation of air may be providedaround the lamp.'

Tt is obvious that when lamps of'large size, as shown in Fig. 1, are used, there is danger of the shade and globe striking the lamp unless some means is provided to avoid it. This is the reason for employing the hinge structure shown. Upon referring to Fig. `1 it will be seen that it the shade and globe are swung downwardly upon the hinge taking the dotted line 40 that edge of the shade` and globe opposite the hinge will strike the lamp; but after the upward eX- tension 33 ofthe shade is freed from the bottom of the holder 5 the link 30 of the hinge permits the shade and globe to swing laterally so that the opposite edge takes the path indicated Aby the dotted line 41, whereupon the continued downward movement of the shade and globe about the hinge will describe the curved line thereby clearing the lamp 34 without removing or interfering with it in any way. A protectl ing'screen 43, preferablj7 of reticulated material, may be secured to the periphery of the shade 27 by means of a clamping ring 44. This clamping ring is preferably channel-shape in construction embracing the edves or beads both of the shade and of the screen with an adjustable locking device, as shown more clearly in Figs. 12 and 13, for holding it in place. This catch comprises abent member 45 secured to one end of the ring 44 with perforations 46 inits opposite sides. 'A pin 47 is inserted through the alined p'erforations and through eyes 48 of a latch member 49. This latch` member 49 cooperates with a fixed catch 50 on the other extremity of the ring from which'also projects a tongue 51 adaptedto be inserted in the member 45 beneath thelatch 49. The

seif'eral perforations 4G kprovide the adjustment necessary fork clamping the rings in position. n f

-. It is also contemplated that the globe (Fig.

5) may be connected directly to the shade y or to the holder by means of a separate fasteningldevice, as shown by Figs. l() and 11.

In this case the holder 5 has secured to it one orv more Xed brackets 52 or adjustable screws 53 and is formed-on one side with a f perforation 54 through theholder with lugs 55 at the side thereof on the outside. A lever 56 is pivoted in the lugs 55 and has an arm 57 adapted to be engaged by a catch 58 pivotally mounted on ascrew 59. In order to insert orr remove the globe 35 the catch 58 is rotated as shown in dotted outline in Fig. 11, thearm v57 is depressed whereuponfthe globe 35 may bev inserted or removed, and if inserted the lever rotated to s To prevent unauthorized removal of the clamping ring 44 and the droppingiof the shade 27, seals 60 are provided, such forexample as a wire loop with its ends leaded together. A wire is inserted through the catch 50 after the. latch Vmemberis pressed over it to lock thev ring 44, and another wire is inserted through catch 3l in a similar manner, it being necessary to break the wire or seal to open the ring or shade.

At the bottom of the globe 35 is a screen G1 larger than the aperture 39, simply laid therein and held by its own weight.- This screen is `to prevent the entrance of bugs and insects which gather' about a light oi' this kind, clogging and dirtying the globe unless some means is provided to exclude them.
