sclsims. (or. 240-148) The invention relates to improvements in lighting fixtures and is more particularly concerned with the construction and m harp on a. lamp fixture.

Lamps such as table lamps having a single light bulb mounted vertically on the upper end of a standard usually are provided with a harp which embraces the light bulb so as to support a lamp shade arranged thereove Conventional harp construction is such that the costof manufacture frequently is excessive and further it often is extremely difiicult, if not frequently impossible, to equip such a lighting fixture with an easily replaceable but firmly held disk arranged to difl'use and defiect light rays upwardly through the shade. It is, therefore, invention to provide a lamp fixture with novellv constructed means adapted to facilitate ready mounting of such a disk;

Another object of the invention is to provide a lamp fixture with a harp not expensive to manufacture but assemble and highly eilicient in Another object is to provide which may be easily vention will be apparent from the following description and claims and are illustrated in the accompanying drawing which illustrates a preferred embodiment and the principles thereof and which is considered to be the best mode contemplated for applying that principle. embodiments of the invention embocbing the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the spirit of the present invention and the purview of the appended claims.

In the drawings:

Fig. 2 is a longitudinal sectional view of the lighting fixture taken substantiallyon line 2-1 of Fig. 1 and showing the lamp socket in elevation.

Fig. 3 is a perspective sleeve for the harp. a

The invention is particularly adapted to be embodied in the construction of lighting fixtures such as. for example, table and dresser lamps. wherein a lamp socket Ii is carried on the upper end of a vertical standard dying features of the pres- L-slot so as to prevent view of the mounting u. 'm socket u u ut within an ornamental cover which in the present instance includes a substantially cylindrical side a bottom wall it firmly secured to the side wall and formed with an internal flange II to be fitted snugly about a bushing I! nor. mally employed to retain such a cover in place around the lamp socket. The cylindrical side wall ll of said cover has an opening I8 through which the usual switch-knob it of the socket ii may upper marginal edge is formed with an external annular fiange 2| having its marginal periphery rolled upwardly and inwardly to provide a beaded finish as at 22. I The diameter of the cylindrical side wall It of the cover is substantiallylarger than thediameter of the lamp socket so as to provide a relatively wide annular space 23 therebetween. The space 23 is adapted to receive therein constitutes the mounting base for a harp 25. As

shown, the harp 25 is fashioned from a length of rod suitably bent substantially U-shaped to include a horizontally disposed medial portion 28 and a pair of downwardly extending leg portions 21. The leg portions 21 are adapted to extend into the sleeve It and be secured firmly thereto as by The harp construction including the harp It and'sleeve 24 is mounted upon the lightin: fixture by initially telescoping the sleeve 24 endwise into the open upper end of the lamp socket cover. said sleeve having a cut out portion all adapting it to be positioned with its lower edge substantially in abutment with the bottom is of the cover without interfering with the operation ofthe switch-knob is. A fitting 29 preferably is carried on the medial portion 26 01 the harp II so as to provide a mounting for a lamp shade.

The sleeve is provided with an L-slot having its longitudinal leg'portion 30 opening onto the bottom edge of said sleeve. The slot is adapted to receive an inwardly extending radial-pin It, secured firmly in the cylindrical sidewall it of cover. After the sleeve has been mo lowermost position within the cover,-.said sleeve is rotated suiliciently to carry thepin 3i into the circumferentially disposed portion 32 of the without reverse rotation The sleeve 24 has'an external annular flange 33 on the end thereof extending outwardly of the cover and thisfiange carries an annulus 34 on its bottom face of a diameter substantially greater than the diameter of the sleeve. The annulus is adapted to have its free lower thereof.

'r" oar-ice a sleeve. which "ed endwise into .its 1 withdrawal of the sleeve edge brought ii on the cover when the arts are assembled so as to thereby maintain a predetermined annular space or channel is between the flange a and the rolled peripheral margin 22 on the flange II. a

The channel 35 receives the inner marginal edge of a reflector disk at which may be mounted upon the fixture to deflect light rays upwardly through the lamp shade when the latter is in place on the harp 25. In mounting the disk it is slipped over the harp sleeve 2 prior to its endwlse insertion into the lamp socket cover.

It should be evident at this time that applicant has provided a very convenient form of construction adapting the lighting fixture for ready assembly and disassembly whereby the harp and its mounting sleeve 24 may be easily and quickly disengaged and removed from the cover surroun the lamp socket, and further; that in the event of breakage of the reflector disk It a new disk may be easily and quickly inserted and firmly locked in place thereon.

Applicant has, of course. illustrated and described a construction particularly adapted to the present disclosure of his invention and it u should be apparent that the construct on illustrated can embody a wide variety of modifications without departing from the spirit of the invention or scope of the appended claims.

I claim:

1. A harp construction comprising. in combination, a U -shaped frame, a sleeve within which the leg portions of said frame are secured, said frame being mounted in such manner that the greater portion thereof extends outwardly beyond an end of said sleeve, an external annular flange on the end of the sleeve from which the frame extends, and an annular ring on said flange surrounding and spaced from the wall of said sleeve.

2. A harp construction comprising, in combina- '4 tion, a U-shaped frame. a sleeve within which the leg portions of said frame are secured, said frame being mounted in such manner that the greater portion thereof extends outwardly beyond an end of said sleeve. an external annular flang on the end of the sleeve from which the frame extends, and an annular ring on said flange surroundingand spaced from the wall of said sleeve. said sleeve having complemental securing means 10 in its cylindrical wall.

8. A harp construction comprising. in combination, a U-shaped frame, a sleeve within which the leg portions of said frame are secured, said frame being mounted in such manner that the greater 1| portion thereof extends outwardly beyond an end of said sleeve, an external annular nangeon the \end of the sleeve from which the frame extends, and an annular ring on said flange surrounding and spaced from the wall of said sleeve, said sleeve having complemental securing means in its cylindrical wall, said sleeve having a bayonet slot in its wall to cooperate with means to secure the sleeve in place.
