ELECTRIC-LAMP-SUPPOETING' STRUCTURE.

Application filed. January21, 1922 Serial No. 530,824

To all whom. it may concern:

Be it known that 1, MAX Hnnsuovrrz, a citizen of the United States, residing at Chicago, in the county of Cook and 'State 5 of Illinois, have invented anew and useful Improvement .in Electric-Lamp-Supporting Structures, of which the following is a specification.

My invention relates more particularly,

19 though not exclusively, to electric-socketsupporting structuresof the type which are supported from a. base, as is common with table or'floor lamps. One of my objects is to provide for the supporting of the electricbulb-receiving sockets in a manner to permit the sockets to be adjusted into different positions relative to the part which supports them, preferably to cause the bulbs provide a new and improved form'of combined housing for the electric wires and support for the socket or sockets, and preferably also for switch mechanism controlling the supplying of current to the bulbs, which shall be strong and durable and may be used ina variety of locations and used with either of its wire-receiving tubular portions uppermost; to provide a plural socket construction of the type above 'referred to which will permit of the wiring connecting the socketinteriors, and the switch where such is provided for enclosure in the. casing, being wired before assembly with the housing structure; and other objects as will be manifest from the following description.

Refeiu'ng to the accompanying drawings:

Figure 17 is a viewin sec tional elevation ofthe housing; and Figure 18,a section taken at the line 18 oniFigflfl3 and viewed in thedirection 01"? the arrow. Referring moreparticularly to thestructure illustrated in Figs. 1 to 12 inclusive,

wherein my invention is embo diedin .an- I electricsocket-supporting structure of the type involving a base (not'shown) at which the structure is adapted tobe supported, as forjexampleon a'table or a floor, with a standard rising therefrom and supporting adjacent its upper end, :the upright, or standard, portion, which is shown as formed of a tube,is represented at 19, this tube not only serving as a'support; but also serving,

to enclose the electricecurrent conducting wires which lead to the bulb-receiving,

sockets hereinafter referred to.- The upper end of the tubular upright'19 is secured to a housing member represented generally at 20, as by screwing the member 19 into the hollow depending'boss portion 21 of the housing 20. This boss member 21 is provided as a partof ,a ring-shaped member 22 which isl formed, preferably integrally, wit-h I an upwardly-extending, boss 23 preferably in vertical alignment with the boss 21. The housing portioii'20 also comprises

cap plates

24 and 25 of general dish shape as shown,

preferably. of semi-spherical form, which are adapted to be assembled with the ringshaped member 22 at the opposite ends of the openingtherethrough, in a manner here inafterdescribed, to complete the housing and cause "the latter to beof substantially spherical-form as shown, thetcap-

plates

24 and 25 being each provided with diametrically-opposed outwardly-extending" lugs 26,

at their open sides. The ring member 22 is preferably provided at opposite faces with annular flanges 27 with qwhiclr the cap plates 24and 25 telescope when thelatter are applied tothe member- 22 .v The ring member 22 is also provided with diainetrica'lly-opposed

bosses

28 and 29 which prefershoulders 31 and 32at the ends of these grooves. The

bosses

28 and 29 are hollow, as represented more particularly in Fig. 8, the passages therethrough and represented at 33 Opening into the interiorof the ring member 22,.and the outer surfaces of these bosses Y at'onefface o'f the ring member 22 from the adjacent flange 27 to the grooves 30, containing recesses 34 which extend lengthwise of these bosses throughout the length of the "latter and open into the interior of the member 22. The bosses'28 and 29 atpoints diametrically opposed to the recesses 33, are

cutaway from their outer extremities to the inside of the ring member 22, asrepresented at 'lVhcn the

cap sections

24 and 25 are applied and 11, the

recesses

34 and 35 receive the lugs 26 of the caps which, become positioned on the" ring member 22as disclosed in the drawings, more particularly. Figs. 4 and 11.

- The bulb-receiviiig sockets of the structure are represented at 136, these sockets being formed with hollow shells 37 provided with laterallyrextending hollow portions 38 open ing into the interiors of theshells 37 and to position at opposite sides of. the ring vmember 22 as shown in Figs. 4

containing bo res 39 of circular shape in cross section' adapting ,these sockets to be telescoped at their portions 38, with the a V bosses 28 and '29 as shown in Fig. 11, these I Y i socket portions when assembled with 1 the ring member 22 overlapping the lugs 26 oi the caps 24 and. 25 and holding the latter in I place on the ring member 22. The'p'ortions 38 are equipped with set-screws 41 which extend at their innerends, as represented of the one in Fig. 12, into the c rcumferential grooves 30 in the

bosses

28 and 29, thereby holding these socket members 36 against accidental disengagement from the housing.

member of which the. ring 22 is e: part,

while permitting of the independentrota tion ofthe socketnnembers on this housing except as limitedby the stops 3l and 32 which are provided primarily "to prevent undue twisting of the electric-current-com ducting wires extending, into the sockets,

The socket members 37; contain socket interiors (not shown), in accordancewith common practice, these socket interiors be ing of any suitable construct onand afford-K ing contacts for the lampand, jas shown, be- 7 7 ing formed with ai'i outer screw-threaded vcontactv42 and a centercontact 43. The" wires (not shown) leadingintothe housing 20, for conducting current to the sockets, are connected with a terminal block represented at44 which may be of any suitable construction adapting of the connection of the lead wires thereto as represented at 45 and 46, the various wires represented at 47 48,-

49 and 50 and extending through the bosses 38 and electrically connected with thecontacts of th'e socket interiors referred 'to,'be-

ing connected at the block 44 with the ter-"

ll'llIlZllS

45 and 46 in a manner to' supply cur-- rent to both of these socket interiors, as will be readily understood by those skilled in the art, the terminal block 44 being formed with an outer shell 51 containing wax, represented at 52, for holding the

wires

47, 48, 49 and 50 rigidly in place, and also being provided with a cover section at one r end, as represented at 53, the terminal block a .44 being shown as of the type involving,

switch mechanism operated through .the medium of the the flow of current to the socket interiors 1 referred to.

In the particular arrangement shown the sockets may be wired to the terminal switch mechanism 44 before the assembly thereof.

with the housing structure 20, and .these' parts then assembled by introducing the terminal switch mechanism 44 into the ring shaped member 22, the wires leading tothe- 'socket'interiors being positioned in the bores 33 through the open sides 34 thereof, wherei are applied" upon the cap plates .24and 25 to the ring member 22 to the osition stated above and theportions 38 o the shells 37 pull-chain 54 for controlling telescoped with the

bosses

28 and 29 to a position in which the portions 38 overlap the lugs 26, whereupon the set-screws T1 are turned to extend at their inner ends into the grooves in the

bosses

28 and 29, the lead wires extending upwardly through the pipe 19 and boss 21 of the housing 20 being attached to the terminals and 46 before the cap plates 24- and 25 are positioned as stated. The deviceas shown also provides "or the securing to the upright portion the structure, of a lamp shade, the being se curable at different elevations. fected in the particular structure shown by the provision of a threaded rod which screws into the upper boss 23 and carries two

discs

55 and 57 threaded thereon, the upper end of the rod 55 being shown as provided with anornaniental section 58. By

virtue of the adaptability or" the rod 55 to adjustment up and down on the housing 20 and the adaptability oi the

discs

56 and 57 to independent adjustment on the rod 55, the structure is adapted to support shades at different elevations relative to, the housing 20-and in a manner to present an ornamental appearance.

By providing the

hollow bos es

21 and 28 the structure'may be assembled with the supporting structure, shown in the drawings as an upright, either in the position shown, or in inverted position, or wires may he led in through both of the

bosses

21 and 23 as desired.

While the structure is shown as involving its support from a stand, it will he readily understoot that it may be embodied in a chandelier, in which case the upper boss would connect with the part depending from the ceiling and supporting the fixture and the shade-holding means, ii used, would be connected with he lower boss 21.

The structure shown in Figs. 13 to 18, inclusive, involves a modification of the structure shown in the preceding figures whereby more than two of these socket members 36 may ,e rotatably supported on the central housing member. In the construc} tion now being described'this housing member, represented generally at 59,, is formed of a lower hollow section 60 and an upper hollow section 61, the lower section 60 containing a boss 62 opening into the interior of the housing and correspondinnwith the boss 21 or the preceding figures and the upper section 61 being provided with a boss 62 openi, Y into the interior of the housing and corresponding with the boss 23. The lower housing section 60 is provided with outwardly-extending bosses 6% which extend substantially horizontally, and are shown as radiating from the center of the housing, in the particular construction shown four of these bosses being provided and forming journaling supports for four lamp-receiving This is er? scopes with the wall of-the section'GO at the open end of the latter, is provided with radially-extending lugs 71 'whlch, when the section 61 is assembled with'the section 60,

extends into the slots in the section 60; The portions 66 of the socket member 65 upon being applied to telescoping position as shown in Figs. 13, 14 and 18, overlap the lugs 71, the'reby holding the

sections

60 and 61 together to form the :housing structure, the side wall of the section 61 ,at the open end of this section, being recessed as represented at 72 to straddle the bosses 64. The SOClIGt portions 65 are provided with setscrews, represented at 7 3, extending at'their inner ends into the =g1oove67 and functioning as explained of the set-screwsl of the preceding figures.

In this construction the same shade-securing means are provided as explained of the construction in the preceding figures, the some numerals being applied to similar parts which are carried by the upper housing section 61 instead of, the substantially verti-' cally disposed ring member 22 of the preceding figures.

It will be noted that the construction'of Figures 13 to 18 inclusive permits, when the housing section 61 is removed, the assembly with the section 60 of the terminal switch block corresponding'with the block 141 of the preceding figures, and the wiresleading therefrom into the socket interiors l-:: :ated in the socket. portions 65, into the section 60, in assembled condition, inasmuchv the bosses 6% contain the slots 70, the pull-chain for actuating the switch referred to being represented at'75 and operating in a chain-guide 1 6 in accordance with com mon practice. i Y

It will benoted that in both of the constructions described, the socket portions are rotatably mounted on the central housingmember and may be rotatably adjusted thereon to cause these sockets and the bulbs positioned therein, to extend into different angular positions, as desired. I

Furtherinore it will be noted that a structure embodyingfmy invention may be con structedvery economically, is simple of con struction and presents iighly ornamental appearance.

.The set-screws 41 and 7 3 and 74 as pro videdlm'ay'also serve the purpose, by screwing themto engage at their, inner ends with the bosses 28, '29 and 70, of holding the sockets in any position to'which they are .adjusted on these bosses.
