@Fill EDMUND 0. SCHW'EITZER, fCHICAGO, ILLINOS LIGHTENG Application filed .April 4,

My .invention relates to lig-lutins,` fixtures and'inore particularly to electric lighting fixtures oit' the wall or side brochet type.

ln natures ot this sort there .is usually a side or wall bracket for attachment to the wallor other vertical support and the conductors usually lead directly to the lamp socket or connection at lthe tir-Imre. lit is often desirable to connect an la* pliance circuit or other electrical device o the single a ilXture. lWh-ere the outlet leadsdirechy .to the ture the only possible place of connection ot anotherdevice Vthereto is at theibture itself. Multiple connecting frneinberz h as those comprising a plug having plurality of sockets or other outlets or take-oil connections are unsuited for this purpose, particularly where the artistic or esthetic effect is predominant. i

A shade is usually desirable and in such fixtures the shade is frequently not large enough to accommodate the type ot inultiple connecting nieniber which is inserted into the outlet at the fixture and projects into the shade. Even it the shade is large. enough, attachment of the connecting inember sdiilicult and when attached -the artistic etlectot the liXture is impaired. The lanip or lightis not positionedproperly in the shade, but is usually positioned oli" to one side and the appliance circuit concluetors entend up into the inside 0i the shade. The connecting members which provide an additional taire-od' connection outside the shade are unsightly and require arrangement of the shadev out of its desired position. f y The aim of my present invention is to provide a simple ineipensive fixture of this sort with an additional built-in outlet or taire-.oil connection.

ln the preferred form oi the invention I` provide a bracket for mounting' upon a wall "or other vertical support. A 'socket supported above theV mounting bracket byl a hollow stern or rod forms a mounting for the fixture shade. This socket `has a downwardly opening portion igor support-` ing a `lai/np vertically in the shade :and `an aligned upwardly opening portion for the attachment ot an appliance or other electrical circuit. The conductors which lead to the socket and take-oit connection at the fixture entend. from the wall through and \coinpanying` mounts .the lainp, supports the shade Vand is supported in upright with the accompanying` drawings erfreuen.

are inaslred by the mounting bracket ,and extend .up through the hollow socket supporting stein to the larnp and take-.oliq yterminals at the socket. The additional talreolif provision which is a huilt-in part of the iii/stare permits convenient connection of an appliance or other additional circuit to the fixture Without iinpairinp; the artistic or esthetic leilect ot the iiviture and irrespective `oli the sise of shade employed and without requiring changing the positioning of `the shade. The lanip is at all times po sitioned vertically in ,the center o' the shade .and arrangement offto one side of theshade is not 4rerpiired whenever another circuit is connected to the fixture. ance circuit connectedl thereof lead oil font the fixture. the shade where connection and disconnection is diilicult.

lWhile in the particular fixture which I `shall describe in connection with the ac* drawings the socket which the conductors Wholly without the shade iVhen an afpplii rllhey do not extend up into vio provides the additional talreeoli" connection, i

position above the mounting bracket, itjis to be understood that the invention is noty limited tothe particular arrangement shown. The socket may be supported below the mounting bracket to give a drop instead ot upright ellect and the shade may be supported either in upright position as shown or in inverted position above or below the mounting bracket to give an indirect or semifindirect eiiect.

In order to apprise those skilled in the art .ofthe manner of constructing and using niy invent-ion I shall now describe an enihodiment` oi the invention in connection in which;

`lliplrure 1 is a front elevational viewyoif a. fixture embodying the invention,

Figure 2 is a side elevation of the saine partially in vertical section.

Figure 3 is a fragmentary elevational viewshowing the mounting of the shade upon the double` socket supported at the upper end of the hollow stein carried by the mounting` bracket; and

Figure 4; is an enlarged vertical axial section through the doublesocket, inthe embodiment ot the invention slected for illustrationg 5 the mounting bracket. This bracket comprises hollow supporting arm 7.

Base 6 which is pret'erably madeot sheet desired con` metal drawn or pressed into the figuration` although it may be made solld or otherwise(formed, is attached to the Wall 8 or other vertical support as by means .of screws 9 and masks the outlet through which conductors 14: entend troni the wall. Arm 7 is secured to base 6 by a. machine screw 10 having threaded engagement with a lug proiecting obliquely trom the inside of said arni T into engagement with base 6. Base G and arm 7 may be ot any desired configuration and ornainented or trimmed as desired. The hollow arm 7, which is preferably cast, receives and masks conductors 14 which enter base t trom Wall 8 and extend up through hollow arm T as shown in dotted lines.

A hollow tubular stein 16 is secured to or terminates at its lower end in a head 17 having an opening 18 diametrically therethrough to permit leading conductors 14; into said head 1T and up through stein 1S. Head 17 has a downwardly extending stud 19 l which ustud projects through and is soldered ment with part 32.v

or otherwise secured in an opening in the outer end off arm "l". Stem 16 is bowed out around lamp or light Q0 to permit vertical disposition of lamp 2O in the center of'shade as shown and extends up to'and 1s mechanically attached as by soldermg at 21 to the outer shell 22 of a fitting having aligned sockets 23 and E24: at its opposite ends.

Shade 25 is mounted in a capor mounting bell by means ot'thuinb screwsf?. The upper end ot cap or bell 2G is reduced to snugly embrace shell 22 and said upper reduced end is provided with a bayonet slot 28.

A pin SO projecting troni shell 22 is adapted to engage` in` slot 28 upon arrangement ot cap 2G down over the upper end of shell 22 to secure the cap and shade 25 carried thereby in place. l

Lower socket 24 opens downwardly to receive and support lamp 20 in vertical position there beneath and upper socket 23 which opens upwardly is employed ior the attachnient of an appliance circuit as by means ot a two part plug 231-532, part 32 having threaded engagement with socket 23 and part 31 having prong and socket engage- An ornamental cap 3G is provided for attachment to plug portion 32 when appliance circuit 35 is disconnected. Cap 36 carries a tassel 38 for giving an ornamental appearance and improving the esthetic etlect et' the liXture when the apalso seems to give a better finger hold tor operating the plug 32 as a switch to turn the lamp 20 oli or on at the lamp, when the appliance circuit is not connected. In Figures 1 and 2 cap 36 is shown in place with con- This cap nesting plug 31 of appliance circuit 35 disconnected. ln Figure 3 the appliance circuit is shown connected.

The double socket` contained in shell E22 has a common central Contact ll() (Figure fl-v). Contact ll() is mounted in an axial opening 1n a transverse partition of insulation Ill. The upper projecting end ci contact l0 is headed at l2 and a coiled spring 43 is interposed betueen head t2 and a metallic ring llll on the upper surface ot partition 41 around the arial opening therethrough. The lower end ot' Contact stud Ll0 is headed at d5. Head 45 cooperates with a shoulder 46 in the opening through partition el to limit the upward movement ot stud 40 under the action ot springl 43. @hell 22 is lined with a layer ot insulation i8 and aligned sockets 23 and 2li at the opposite ends ot shell 22 comprise threaded conducting shells mounted within the sleeve or layer ot insulation 4S at the opposite ends thereof. l

Shell 22 is provided with an opening 50 at the upper end ot stein 16 and conductors 14-14 are led into thev double socket inembcr through said opening. One conductor 1ct is electrically connected with central contact #l0 as by soldering it to ring 44 between which and head 4Q spring 113 is interposed.` The other conductor l-l is electrically connected to the threaded shells 23 and 24, as by leading it in and soldering it to one of said shells,l 23-24 and extending said conductor through partition 41 and connecting it to the other shell, as by soldering. It will be noted that central contact 40 is mounted to have engagement with the central contact `of a plug inserted in upper circuit member 23 and is normally held in such position by spring t3 so that the central contact of a lamp or `plug inserted in lower socket 24 cannot make contact with said common central contact ll0 until the latter is pushed downwardly by the plug inserted innpper socket 23. `When the `plug is inserted in upper socket E23 it moves the common central Contact 40 downwardly to bring lamp 20 intol circuit. Consequently, the plug 32 1n the upper socket E23 may serve as a switch fort switching lamp 20 into and out of circui From the foregoing .it will now be apparent that I have provided a simple inexpensive wall fixture having an additional lll) ill!) lll) `tacts, the

a drop fixture with the advantageous lighting eii'ect accompanying the same. The bayonet slot and pin connection between bell 26 and shell 22 provides a highly advantageous mounting for shade 25.

As already pointed out it is to be understood that the double socket may be suspended below mounting bracket 5 instead of supporting in upright position above said bracket as by extending supporting stem 16 downwardly instead ot' upwardly from arm 7 to give a drop instead of upright effect. The terms up and down are used herein not in a limiting but in an explanatory sense. Shade 25 may be supported either in upright position as shown or in inverted position above or below the mounting bracket. l

I wish to call `attention to the novel function of the plug 32 in this connection. It is obvious that instead of having anEdison socket in the shell 22 and then inserting a separable plug having push or prong conpush or prong contacts might be directly mounted in the upper end of the shell. However, there is an advantage in the presentconstruction. rst, in that standard parts are used, and second, the use of the plug 32 in conjunction with the movable axial Contact 40 permits the lamp 20 to be switched ott or on at thelamp, Whether the implement circuit 35 is connected or not. The plug 32 in connection with Contact 40 becomes a switch with an axially extending rotary handle or linger piece lying above the upper end of sleeve 22 and at all times` tition to limit the movement of the stud therethrough` a head at the opposite end of said stud, and acoiled spring interposed between said head and a metallic ring mount-` ed on the adgacent surface of the partition, electrical connection to the contact being had through said ring.

In witness whereof, I hereunto subscribe my name this 3l day of March, 1923. i
