To all whom it may concern: I Y .Be it known that 1, MAX HERSKOVITZ, citizen of the United States, residing at Chicago, in the county of Cookand State of sitionsrelative to the part'wliich supports them,preferably to cause bulbs carried thereby to extend downwardly or in either direction in a substantially horizontal plane.

Other objects are to provide a'novel, simple and inexpensive construction by which the supporting of the sockets, as stated, may be accomplished; to provide a new and improved form of combined housing for the electric wires and support for the socket, or sockets, which shall be strong, durable and ornamental and may be used in a variety, of

locations and used with -either of its wirereceiving tubular portions uppermost and other objects as wil-l be manifest from the following description.

Referring to the accompanying drawings Figure 1 is a view in elevation of the upper end of-a socket-supporting structure pro vided1with a plurality of bulb-receiving sockets and embodying my invention, showing the sockets in a position "in which the bulbs supported therein, and shown by. dotted lines, assume a depend ng,po u

'FigurelO is a- View like Fig. 1 of amodification ofthe structure shown-in the preceding figures. Fig. 11 isan enlarged view in sectional elevation of the structure shown in Fig. 10, one of the bulb-receiving I sockets being omitted and Fig. 12 is a plan v ew of the lower housing-section of the -.Referring to. the construction shown in F igs. 1 to 9 nclusive', myinvention isshown as embodied inan electricsocket-supportingstructure of the type involving a base-(not shown) at which the structure is adapted to be supported, as for example, on'a table ora floor, with a standardrising therefrom and supporting"adjacentj'its upper end the upright or standard portion which is shown as made .of a'tube, as represented at 8, tl'iistube not only serving as a support but also serving 2 to enclose the electric-current-conducb' in'g wires which lead to the bulb-receiving sockets hereinafter referred to. The upper endof the tubular upright 8 is secured to a housing member-represented generally at 9,

as by screwing the member 8 into tho holl'ow depending boss-portion 10 of thehousing 9. The boss member 10 is provided as a part of a ring-shaped'member 11 which is'formed,

preferably. integrally with an upwardly-ex tending b0ss12, preferably in verticalaligm ment with theboss 1 0. Tlhe-housing portion 9 also comprises cap-plates 13 of gener'alr dish'shape, as shown, preferably of=semi-- spherical. form, which are adapted to be as sembled with the ring-shaped member 11 at the opposite ends of the, opening there through, in a manner hereinafter described, to complete the housing and cause the latter to be of substantially spherical form as provided at opposite faces with annular res cesses 14-for receiving the marginal edges of the sections .13 in the assembly of the lat-" ter with the ringmember 11, as shown in Figxqo. -The ring member 11 contains diametrically opposed radially extending openings :15 which are preferably horizontally disposedk l .5

Thecap sections 13 are each providedwith a recess portion 16 forming a bottom wall 17 extending substantially parallel with the The ring member. 11 is preferably axes of the openings 1 5,.these portions 16 being preferably provided by deflecting the metalof these cap sections, the recess 16in one cap section extending ad acent to the part in {which one -of the openings is ..lo.

cated and the recess 16 in the other cap section extending at the oppos te side of the structure, all as shown in Fig. 5. The cap sections 13 are removablyl ield in place'on prising, hollow shells 21 eachfprovided with the member 11, in the position above stated;

by screws 18 which extend through "openings in the portions 17 ofthe OELPSBCQIOIIS .13 and screw into threaded openings 19 m the meme ber 11. i I

The bulb-receiving'sockets of the structurearerepresented at 20, these sockets coma;hollo'w g0ose1-neck portion 22 openinginto theshells 21through the ends of the latter. The. other ends of the goose-necks extendat an angle, preferably a right angle, to the longitudinalaxis of the shells 21 andare providedwith shoulders 23, shown as of annular, form, jand set back from-the extremities of these .endyportions, these-shoulders being shown as formed .by expanding :the' metalfforming these goose-necksat said por tions. The portions of the goose-necks-just refe-rreclto,1a11d which extend into the openings 15, and are rotatable therein, contain peripheral grooves 24-shown as extending throughout a portion only of the circumfer ences of the gooseenecks and affording shoulders 25 and 26 at'oppositeends thereof, the various parts being: so. arranged that the screws '18 when screwed to, a position in whichthe cap sections 18 are held in place on the-ringmember '11 will extend at their inner ends into the respective grooves 2 1,

- thereby holding the socket members against accidental disengagement-from the member 11, while permittingctr-the. independent ro-v tation of thesocket members on this member, exceptas limited by the stops 25 and 26 which are provided primarily to prevent unduetwisting of the electric-current-conducting wires leading into the socketinembers.

The provision of the grooves 24,:of the a length shown, adapts the socket members to be swung'from .a substantially vertical position to substantially horizontal positionand vice versa.

Thegooseneck portions 22 areeach prefenablyjformed of two sections of similar shape and size and each of seini circular shape incross-sectionwhich extend in edgeto -edge abutting relation, theseiv sections being united along their'abutting: edges, if desired,;by solderlng them. It is preferred thatatzthe ends thereof at which theyextend through the end-walls of the socketshells 21 the metal bespun to'interlock with the inner, surface of the shellsas shown .at 22 in -Fig. 9, .thegoose-necks above the shells 21 beingaprovided-with shoulders 23. The

contact .27 anda center contact 28.

socket-portions 21 preferably connect with the goose-necks between the ends'ot the latter to render :the structure rigid, as repre--' sented at 21 this connection, as. shown, b.e-'

ing, formed by stamping a'tub'u lar extension 21 from'the metal of the socket 21 to fit atv its endagainstthe adjacent sideof the I goose-neck, and filling the extension 21 with solder as represented, at 21 which also serves to solder atthis point the joint between the goose-neck sections. I

y constructing the. gooseen-ecks {as ,"stated, they. may bemade economically and: of relativelysmall diameter and" fastened securely I in place.

.The socket members contain socketinteriors (not shown) 'in' accordance with' common practice, these socket-interiorsbe ing of any suitable construction. andiafi ord ingcontacts for the lamp, and, .as shown, being formed with an outerscrew-threaded The wiresleading into thehousing; 9 throughsthe pipe 8fare represented at '29 and 30, these wires extending into the interior of. themernber 11 ,wh'erethey ,are connected with the wires 31, 32, 38 and 34 which are-threaded through the goose-necks 32 and connect with the terminals of the socket-interiors.

The provision of the member 9:as.a hollow structureand formedof sections isdeprovision of: athreaded'ro'd 35which-screws into the upper boss 12 andcarriestwo disks the rod being shown as provided" with anornamental section 38. By virtue ofthe adaptabilityof the rod 35.to its adjustment up and down on the housing 9 and 1 the adaptability of the disks 36 and 37 'to independent adjustment on the .rod '3'5,the structure ls adapted to support shades at different elevations relative tothe :housing member and in a manner to present an ornamental appearance. 1

By providing the hollow bosses 1O= and121 the structure infaybe assembled with the supportingstructure, shown in the drawings as an upright, either in'the position shown. or in inverted position, or wires may be led in through :bothof the bosses 10-and 12 as desired. While the structure is shown as involving its supportfroma stand, it will'ben'ea'dily understood that it may be embodied in a chandelier,1n which case the upper'boss 12 would connect with the part depending from 36 and37 threaded'thereon, the upper'end of the ceiling and supporting the'fixture, and the shade-holdingmeans, if used, would be connected with the lower boss 10.

In the construction shown in Figs. 10, 11 and 12 the body of the structure, instead of being made as described of the construction of the preceding figures, is formed of a lower cup-shaped member 100 having adepending boss 101 corresponding with, the boss and an upper inverted cup-shaped section 102 which with the section 100 completes the body-member. The section 100 contains a series otradially-disposed openings 103 in its side wall, near its upper edge, for receiving the inner ends of thebulb receiving sockets 20. The section 102 is peripherally flanged, as represented at 104 and is apertured to receive screws 105 whichscrews into and through, openings 106 in the section 102 and into the grooves 24 in the goosenecks 22 and serving the same purpose as the screws 18 of preceding figures. By this arrangement, it will be noted, any desired number of socket-members maybe provided in the housing. WVhile only two of such members are provided the number may be increased, if desired, by providing as many of the openings 103, as desired, to correspond with the number of the members 20 to be provided. The bushing 107- provided in the opening 108 in the top of the section 102,-receives .the stem 1,09 corre- SpOlKl'lllg to the stem 35. Y

It Will be noted from the foregoing that a structure embodying my invention may be economically mianuiactured, is simple'of construction, and the parts thereof maybe readily assembled.

Vhile I have illustrated and described a particular construction embodying my invcntion, I do 110t' \V1Sl1 to be understood as intending to limit it thereto, as the same n'iay be variously modified and altered without departing from the spirit of my in volition.
