LIGiiTING-IXTUEE Specification of Letters Patent.

Pateimai oct. 2s, 1919.

Application led January 17, 19,18. Serial No. 212,261.

To all whom t may concern:

Be it known that I, CHARLES ERNEST JONES, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lighting-Fi tures, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to lighting fixtures and more particularly to wall brackets for incandescent electric lights and has for its object to provide improved means for attaching the bracket to the wall which is invisible, as well as simpler, cheaper and more secure than the fastening devices hitherto employed.

To this end the invention contemplates a construction in which the base of the bracket and the wall are provided with cooperating hook and ring devices hidden by the base when in engagement and adapted to be brought into and out of operative connection with each other by sliding the base over the wall.

Further features of the invention will be described in connection with the construction shown in the` accompanying drawings, in Which;-

Figure 1 is a side elevation partly in section, of a bracket embodying the features of improvement provided by the invention;

Fig.- 2 is a sectional view taken on the line 2 2 of Fig. 1; l

. 'Fig'. 3 is a perspective view showing one of the connecting elements; and

Fig. 4. is ,a perspective view of an ornamental candle tube which may be employed with the improved fixture.

The bracket generally designated as 10 is detachably connected to the wall 11 by means of a wedge device adapted to press the edges of the base 12 of the bracket against the wall. In the form of construe tion illustrated this wedge device comprises .coperating ring and hook elements 13, 17,

either one of which, as 13, may be con-V nected` to the wall while theother element,

as 17, is connected to the base of the bracket. When the ring 13K is attached to the Wall, as shown, this may be accomplished in various ways, as by screwing it onto the threaded end of a pipe 14: extending from an outlet box 2 1 of well-known type and securing it in adjusted position thereon by means of a set Screw 30. To permit of the attachment of the ring element 13 to the wall, when no outlet boX, as 21, is provided, this element is preferably formed with an extended base 16 having apertures 15 for the accommodation of attaching screws (not shown).

The hook 17 is attached to the inner face of the base 12 preferably with its end eX- tending downwardly. The end portion of the hook is formed substantially straight but slightly inclined downward toward the wall so that the inner face of the hook in coperation with the inner face of the ring 13 acts as a wedge to press the base 12 against the wall. While the base 12, as shown, engages the wall only at its margin, its bulging form serves to impart sufficient strength against crushing to permit the employment of a substantial amount of fo-rce in .applying the hook 17 to the ring'13 without de orming the said base.

Either the hook 17 or the ring 13 or both of these parts may advantageously be made of malleable metal to permit of these parts bei-ng bent in accordance with variations in the distance between the inner face of the base 12 and the surface of the wall in different brackets with which the device may be employed, By making the ring 13 normally of greater width than depth, measured from the wall outwardly, a slight deformation of the ring will secure a greater amount of adjustment in the depth of the ring than would be the case if the ring were originally circular.

In using the particular construction illustrated, the bracket is attached to the wall by sliding it down the surface of the latter to bring the hook into firm engagement with the ring 18. As this sliding movement ltends to mar the surface of the wall a piece of paper (not shown) may, to advantage, be placed between the wall and the bracket before bringing the hook into engagement with the ring. After the bracket is in position the projecting portions of the paper may then be torn ofll around the edge ofthe base 12.

The bracket is then firmly but detachably mounted on the w'all without any means of connection being visible. Previously it has been customary to attach the brackets by Screws or bolts passed through the base 12 and these not only tend to distort the base but also mar the ornamental appearance of the bracket.-

llhe base 12 may conveniently be formed by pressing sheet metal into the desired concave, ornamental form. 1n any case the base 12 should be recessed not only to accommodate the ring 13 and the hook 17 but also the spliced ends of the wires (not shown) leading from the outlet box on the one side to the lamp bracket on the other side. For attachment to the arm, as 19, of the bracket 10, the base 12, is centrally apertured for the reception of a threaded nipple 1'8 provided at the inner end of the said bracket arm. By screwing the hook 17 onto the nipple 18 the base may be held firmly in position' against a flange 20 formed on the arm 19 adjacent the nipple. rlheouter part of the bracket may be of any suitable construction. 1n the form illustrated the bracket is provided,` at its upper end'with an upstanding lamp socket 23 of common type.

, Between the lamp socket 23 and the arm 19 is arranged a candle cup 24. If desired the candle cup 24 may be employed to support a candle tube 26 which .is sleeved over and conceals the lamp socket 23 and preferably also projects a suficient distance beyond the lamp socket 23 to extend to the lamp bulb 22. By forming the candle tube 26 from a composition material having a White outer surface a very desirable ornamental eect is obtained.

The provision of a laterally projecting switch handle on the lamp socket 23 is permitted by slotting the candle tube 26 `from its lower end, at one side, as at 27 (Fig.

The use of a more expensive .wall switch is thereby avoided while still permitting of the use of a candle tube.

I claim as my invention:

1. 1n a lighting fixture, in combination, a bulging sheet metal base, a lamp bracket projecting through said base, a malleable hook secured to said bracket, said hook projecting upwardly and backwardly then downwardly from the bracket, a ring adapted to be attached to a wall, said ring being of greater dimension in a plane parallel with the wall than in a plane perpendicular with the wall and being formed of malleable materia-l, whereby both said ring and said hook or either of them may be deformed to vary their span so as to hold the base firmly to the wall.

2. A lighting fixture supporting eye comprising a base having a threaded aperture, a perforated ear -pro]ecting at one side of the aperture, a hook receiving portion spaced from said base and malleable connecting portions supporting said hook receiving portion in adjustably spaced relation with said base, the adjustment being obtained by deformation of said connecting portions.

3. In a lighting fixture, a base adapted portion whereby the spacing of said hook engaging portion may be obtained by deiormationof the connecting' portlons.
