8 Claims. (Cl. 2441-81) l This invention relates to improvements in electric lamps, torches and the like ornamental illuminating devices.

An object is to provide a fixture of the above type, having a plurality of incandescent lamp bulbs, with easily accessible means for separately controlling each of the bulbs.

An additional object is to provide a lighting iixture with which both direct and reflected 1C*y illumination effects can be produced; and to this end it comprises a reflector of special design and means through which diffused light can be radiated or transmitted in the amount desired.

In its preferred form the invention comprises a oor lamp by which a large portion of the.

illumination is thrown upward towards the ceiling and another portion is distributed horizontally;

with an enveloping shade to moderate the horizontal beams and diminish their intensity if necessary.

It is another object of the invention to provide a lamp of very artistic appearance, but simple in construction, and capable of being easily made and assembled.

Further object is to provide a lighting appliance all of the parts of which contribute to the general decorative effect, while at the same time sustaining all the mechanical relations necessary to constitute a complete structural unit.

The nature and advantages are completely set forth in the description that follows and the novel features are pointed out broadly and specifically in the appended claims. This disclosure, however, is illustrative only and I do not wish to be limited to the construction illustrated herein; but reserve the right to make changes in the shape, size, design and arrangement of the various parts to the full extent consistent with the scope of the invention and the underlyingprinciple thereof.

In the accompanying drawing, in which is shown one of the various possible embodiments ofthe invention:-

Fig. l is a vertical section through a lamp according to this invention.

Figs. 2 and 3 are side views of bracing members used in the construction of said lamp; and

Fig. 4 is a sectional view of a detail.

On the drawing the same numerals identify the same parts throughout.

The numeral l indicates a suitable support which may have the form of a tubular standard or column, adjacent the upper end of which is mounted a bowl shaped head 2. Upon this head and affixed thereto is a dish-shaped lamp-carrier 3 to the bottom 4 of which are attached a suitable CIT number of fixtures in the form of lamp sockets 5 for the incandescent electric lamps 6; The bottom 4 of the carrier 3 is convex, and the sockets 5 are' of the well known construction with internal threads to enable the threaded necks of the lamps 6 to be attached by screwing them into these sockets. Y

The sides 7 of the carrier 3 make a well dened angle with the bottom 4 presenting an outside edge 8 which engages and rests upon an annular shoulder inside of the head 2; this shoulder being indicated at 9 andbeing surrounded bv the upturned rim 10. The bulbs of the lamps '6- may be transparent or translucent and may have any color desired. They are surrounded bya translucent bell or globe 11 which is open at both ends, the lower end being seated upon an annular shoulder 12 in the carrier 3 above the bottom 4 thereof. The bell 11 expands or flares considerably in an rupward direction; and at the top it is lined with a metallic reflector element 13, which likewise flares according to the configuration of globe 11. At its upper and larger end the bell is formed to provide an annular bead 14 within which rests the rim 15 of the reflector. With this construction, part of the'light of the lamps passes through the sides of globe 11 and is radiated directly; while another portion of thelight from the lamps 6 strikes the reflector 13 and is reflected upward and to some extentoutward. Owing to the fact that the bell 1l is iiared or expands toward its end remote from the carrier 3, the sockets 5 of the lamp 6 haveoplenty of room and the axes of the sockets and the lamps 'can be divergent according to the convexity of the bottom 4. f The sockets 5 can be aflixed tothe bottom 4 of the carrier 3 inany suitable manner and I have shown diagrammatically fastening means at 5 16. The sockets will of course incorporate suitable 'switching means which may be operated by pull chains `17 one depending from each socket said chains passing through the respective openings 17 in the carrier 3. Hence, the supply of 100 electric current to each of the lamps 6 can be controlled and any one or more of'the lamps can be illuminated or extinguished independently of the rest.

The top of the column 1 is surmounted by a 105 cap 18 upon which rest bracing members to engage and steady thelamp structure just described. The'bracing members in question are illustrated in Figs. 2 and 3, and each comprises a pair of upright arms to the upperends of which the head 2 is ailixed. Though the bracing members are two in number, more can be utilized if preferred; and if two are present they Yare disposed so that the planes of the arms thereof are at right angles. One of the bracing members,

'for example that shown in Fig. 3, comprises a perforated base 19 from which arise the bracing arms 20 which have concave surfaces 21 at their upper ends to fit against the outside'ofhead 2; and are secured by screws 22. The other bracing member, as shown in Fig. 2, comprises a similar perforated disk 23 on the top of which is a boss 24; land from the disk 23 rises as before the bracing arms 25 having upper concave ends 26. sition the disk 19 rests upon the cap 18 and disk 23 rests upon the first disk 19. The screws 22 of course have suitable threaded openings in the tops of the bracing arms 20 and 25. 'Ihe bracing members, and particularly the arms thereof, can have any desired ornamental shape; and the construction just described can easily. be made by casting each bracing member, comprising the two arms rigid at their lower. ends with a disk, in one piece. When the lamp is made up the head 2` and parts associated therewith are thus braced at four equidistant points.

The column 1, as above stated, is hollow and the cap 18'islikewise centrally bored out, one end being vthreaded ifdesired to engage the column 1 and the other end threaded to receive and hold a tubular extension 27 which passes through the perforations' of the disks 19 and 23. This extension also passes through the knob 28, which rests upon the boss 24; and the extension also projects through the bottom of the carrier 2. It is surrounded by a spacing sleeve r29 which abuts the knob 28 at one end; and its opposite end engages a similar element 30; the lengthV of this spacing sleeve being such that the element 30 affords a rest for the head 2. Within the head 2, the eX- tension 27 receives a washer 31 and has screw threaded engagement with a hickey `32. The

bottom 4 of the carrier 3 is perforated in line- 18 to the interior of the carrier 3 the electric' conductorsA can be disposed in the support 1 and passed up through the extension 27 so'that they can be connected at their upper` ends in the manner required to supply energy to all of the lamps 6.v n

n A suitable shade isshown at 34 to surround the globe 11. It has internal lingers 35 to rest upon the upper edge of globe 11 and these fingers may be connected by ring 36.

The illuminating device is thus strongly easy to assemble and pleasing to the eye. Part of the light is thrown upward bythe reflector 13 and partis radiated, softened and diffused Yby the globe 11. The light passing through the globe can be further moderated by the shade 34.

It will. thus be seen that there is herein described apparatus in which the several features of this invention are embodied, and which apparatus in its action` attains the various objects of the invention and'is well suited to meet .the requirements of practicaluse.

When the two bracing members are in pomade,`

As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense. .Y
