NATHAN L. URELES, 0F' NEW YQRK, Y.

LIGHTING- FIXTURE My present invention relates to lighting fixtures and is more especially concerned with a fixture of the type, the canopy, panel or base of which embodies a casing or shell for a switch or a lamp socket within the construction thereof.

It is among the objects of the invention to` provide a lighting fixture of the above type, the canopy or panel of which may be securely installed against the ceiling, wall or ioor, the casing of the-switch or socket being securely located therebehind, with the operating element of the switch, if any, conveniently accessible, without the'need for disfigurthe canopy or panel or rendering the same asymmetrical; which obviates the need for different hickeys or for special adaptors to suit various depths of outlet boxes or panels, and is yet positioned with the utmost facility, dispensing even with the need for preliminarily adjusting the parts to'suit the dimensions of the outlet box, canopy-or panel.

In aipreferred embodiment I provide a hickey which serves to mount the switch or socket aswell as the panel or canopy and is itself mounted on the stud, cross-bar or other ,part of the outlet box. The hickey has its parts displaceable toward each other for 'adaptation tothe depth of the outlet box and canopy or panel, said parts being automatically locked to restrain extension of the hickey, so that the panel or canopy is securely heid in position by the hiekey. Preferably y a part of the switch case construction mount- Aed on the hickey extends through the panel or canopy and is encircled bya nut, ring o-r other device for securing the canopy or panel in position.

In the .accompanying drawings in which are Vshown one Aor more 'of various possible embodiments of the several features of the invention, i y V Fig. l is a view in longitudinal cross section showing a` ceiling fixture or canopy.

Fig. 2 is a dropped perspective View showing the constituent'parts of the hickey.

3 is a perspective view of a preferred form of hickey therefor in collapsed position.

F ig. 4 is a view in longitudinal cross section showing a walll bracket application.

Application filed December 2, 1927. Seria1-No. 237,190.

Fig. 5 is a dropped perspective view illustrating the hickey or bracket of the embodiment of Fig. 4iand, I y

F ig. 6 is a fragmentary View similar to Fig.

4 illust-rating anotherv application to a wall 55 bracket. y l

Referring now to Figs. l, 2 and 3 of the drawings I have shown a ceiling bracket fixture comprising any outlet box l2 having the. usual stud 1l and a conventional canopy l5 60 on which may be mounted ashade holder l5. To support the usual lamp socket S` and to carry the canopy I provide a hickey whichV in this case is of collapsible construction for ready adaptation to thevarious depths of 65 canopy and4 outlet box.

The hickey, in this case, illustratively comprises three interiitting sections, A, B and C. The innermost of these sections A, which I, y call the stud seetionfhas illustratively an in 70 turned threaded socket l() for attachment on the stud l1 of the outlet box l2. The outer or canopy section C preferably includes the integral split ring 13, encircling the shank of f the lamp socket S preferably immediately be- 7'5 low the shoulder 9 thereof, and clamped thereinto by a clamp screw 8 through lugs 7 integral with ring 13. Other means for rigidly combining section C and the socket may be employed. f

y The sections A, B and C of the compound hickey are preferably'in telescoped relation and are shown embodied as yokes, the stud section A having a pair of upstanding lateral yoke arms 18 and 19 encircled by the prefer- 85 ably rectangular open base frame 20 of the intermediate' section rIzzi which has upstanding yoke arms 21 and 22 flanged over at 23 to form guides or tracks for the sliding move-v ment thereof relative to the respective arms 9o ed position, the length of the hickey is nearly three times the length of an individual yoke.

I may employ a pawl and ratchet connection between successive yoke sections of the hickey. Illustratively, the head section has a pawl, preferablyv a. spring arm 27, riveted welded or soldered'in place at its base. The pawl coacts with ratchet teeth 29 in the corresponding arm 22 of the intermediate yoke piece B. In a preferred construction, the ratchet teeth 29 are struck out of the metal of the yoke arm, entirely between the sides thereof. Illustratively, the ratchet presents a herring bone shaped aperture presenting integral teeth 29 extending inward from opposite sides of any otherwise rectangular aperture 30. The teeth 29 present square edges 31 above (in Fig. 1) and oblique edges 32 below, V"so that the pawl will overrun the ratchet when the yokel pieces are pressed together and the square edges 31 ofthe ratchet teeth 29 willresist and prevent extension or separation of the yoke pieces, since the squared end of thejpawl tooth cannot be pulled therepast. VOther, equivalent ratchet constructions may be used. I

I provide a second spring pawl 35 on the right arm of the intermedia-te section B, coacting with a ratchet construction 36 on the corresponding arm of the stud section A, and identical with the ratchet of the intermediate y section B.

The opposite arm 19 of the stud yoke is preferably longitudinally bifurcated to afford a channel 37 through which extends pawl tooth 27 to engage the ratchet 31, even when the stud yoke is telescoped inward into the intermediate yoke, as in Fig. 3. As shown, the arms 19 and 22 of the stud and inter- -mediate yokes respectively, extend between the yoke arm 25 and its pawl arm 27. Preferably, each ofthe pawl arms has rigidly affixed near the tooth end thereof a push button 38 on the outer end of a pin 39 aflixed thereto andprotruding from the corresponding yoke arm. Yoke piece A has inturned teeth 40 at the extremity of the ratchet 36 thereof, against which the tooth of the pawl 35 abuts in extreme extended position." Yoke ratchet 30 has similar teeth 41, similarly arresting the tooth of .pawl arm 27. Yoke piece B has a tooth 43 at the end of its flange tracks 23,y

'andarm 24 of the outer yoke piece has a similar tooth 44. The'teeth v43 and 44 extend` at'right angles to each other and thus edectively limit the separation of yoke pieces sary, to maintain the push buttons 38 de-I pressed for disengaging the corresponding pawl with the ratchet, while drawing the yoke elements apart.

' With the various types of canopies, panels or bases of lighting fixtures now in vogue, the three-section compound hickey affords the range of length required toaccommodate any installationk from the shallowest canopy on the shallowest outlet box to the deepest canopy on the deepest outlet box. Obviously, however, the concept of my inventionmay be carried forward, if necessary, to provide a compound hickey of four or more relatively telescopedsections. On vthe other hand, if desired, the hickey may be made in but two sections, a stud and a head section, directly connected by a pawl and ratchet or equivalent connection, which construction would accommodate a practical range of installations, in fact, would be suitable in all but the more extreme cases.

n To install my fitting, the compound hickey (in which the lamp socket shell S has been previously positioned by tightening split collar- 13 thereabout) is threaded at its stud section 10 upon the outlet box stud 11. The electric conductors passed through bushing 51, are connected to theterminals within the lamp socket S in the usual manner. rlhe hickey being preferably in fully extended position, canopy 15 is applied thereover with the end of the lamp socket S projecting therethrough. Thereupon a nut, threadedl vis securely pressed against the ceiling or other wall. VThe canopy cannot now b-e pulled out by manual tension, since the pawl and ratchet connections are securely locked to prevent extension of the compound'hickey.

By my invention, it will thus be seen that the application of the canopy is accomplished with vthe utmost facility. No hickeys of special size need be kept in stock, nor need the universal'hickey be adjusted or specially set by distinct preliminary operations, or adjustments or by the use of adaptors, nor'are successive approximations by trial and error necessary, nor groping to locate concealed screwV holes. The complete installation of negarse the fixture is accomplished in buta fewseconds.V The installed-construction presents no protruding screws or holes that tend to ydisligure the canopy. The application moreover, does not interfere in any way orrender it more diflicult to wire the fixture;V i. The socket may be `of the pull chain or of; the keyless or switchless type.

Disassembly is accomplished with the same facility as installation. ,For thispurpose, the screw Vcollar 52 is merely` unscrewed, whereupon the canopy can be removed andv the compound hickey with its lamp socket switch S can be unscrewed from the studll. lith the hickey thus removed the lamp socket lswitchcan be removed and replaced. The

hickey can be re-extended by pulling, vWhile depressing linger piece 38.` The hickey can then be re-applied to the same'or to other fixtures in the manner above described. i l

In the embodiment of Fig. 4 is shown a wall bracket application. I haveillustrative- 4lyi shown a collapsible hickey of but twosections, though three sections, as'shown inthe ceiling. lixture are preferred. The hickey shown comprises a stud section A threaded upon'the stud 11a of the outlet box, and' a conary canopyswitch 60 may be employed, illustratively the conventional circular switch shown, the 'threaded' shank 61 of Awhich is merely screwed through an opening 62 in the end of the outer section C of the'hickey.. Illustratively each section of the hickey j is shown of angle shape withfbut one arm, instead of a pair of arms Vas inthe embodiment of Fig. l, although a pair of such arms may 'be employed if desired. TheQp'awl land ratchet connection between thetwo sectionsofthe hickey may be similar to `thatofany! twoof the sections in the embodiment ofFig l'and need not therefore be fully c lescribed.v (Corresponding parts bear Athe 4same reference numerals with exponenta. f 'l f From the foregoing it will `be understood that for installing the Wall bracket, the hickey with the switch 60 vthreaded thereinto,`is extended to itsutmost and mounted at itsstud section A upon the stud 11a. Thereupon the panel 15a is passed at itsjcentral aperture .over the shank 6l of the switchand pushedl to- Ward the wall. VThe pushing thrustgagainst the end of the compound hickey will lcause the latter automatically to collapse, 'the ratchet'laoverriding the piawl27a`i1ntil the edge of the panel-has reached the Awall. Thereupon nut 63Vis simply threaded upon the switch shank thus clamping'the panel in position. Upon screwing switch button 64: on the switch 'spindl'e the assemblyis completed. j v

It will be seen that Vwhile the compound hickey readily collapsesfas set'forthypulllbr tension upon the nut 63 will be ineffective' to cause the hickey'lto reezdendl since therpawl `requirements of practical use.
