it -knoiwli that I,' LAURri'z. ANDER- .sEN,.a citizen of the United States, residing at Waterbury, in t-hecounty of New Haven; and Stat -ofsCOhneoticut, have invented a certain new and useful Improvement in. Shade-Holders fol-'1 Electric Fixtures or Electroliers, of which the following-is a specification.v I

-'My-1nvent-ion relates to electric light fiir? 'tures' or electroliers, and particularly to an improyed holder for shades or pendant spheres or-divided spheres, with the'object- 'of simplifying existing structures, reducing thercost, dispensingwit-h. small auxiliary parts, such as screws',- and particularly with thenece'ssity for-dismantling the socket in order to attach thereto the shade holder and Sh d-- v 'Incarrying. out my invention, I employ two essentialfparts, the one to be passed up t'hrough the shade oi-"sphere, and over the lamp and-.sockeh; and the other, after first;

. being passed ..upoverv the lamp and socket,

*of the parts,

to then be passed down; over the first named part and be engaged therewith to hold the shade or sphere bet-ween the lower portions the shade or sphere; and said parts in turn suspended from the socket and. devices to which the socket is connected.-

T'hese two parts are. axially movable, one

over .or outside the other, and they are adapted to be removably connected in a substantial manner, all of which "is more particularly described 1.111 the drawing, Figure 1 is a vertical central section, r'epresentingthe device ofmy improvement, theshade and, the lamp socket .being shown in dotted lines, Fig. 2 is a plan of the inner pa-rt shown in Fig. 1. Fig. 3 is a vertical section-representin the inner parts only. Fig. e is a detache elevation from within, showing the connected. relation of the main and-auxiliary parts of the innermember on the section line indicated inFig. v

a 'rep esents a tubular supporting body of sheet metal having an out-ward flanged lower edge at and preferablyhavingperforations2. a re" eSentsthescrew-threaded portion of the odyja. The upper portion. ofthis tubular supporting body a has connectedthereto the dome sections, 2) 6 These are centrally divisible and apertured a, at the upper edge of the sleeve is adapted hereinafter and arevconnected in a hinged relation to the upper part of the supporting body a,

that is to say,- at opposite sldes' of the-body parts at, there are elongated narrow openings 45, and the lower edges of the, portions 66 are provided with engaging projections fi, 7 and 8, in two sets. These project through the slots t 5 and while two of the projections 6 and 8 are turned down, the intervening -projection 7 istu-rned up, so

that not-withstandingthis simple and ready means of connection, it is quite impossible Patented May 14, 19 12,

screw-threaded to separate the dome sect-ions bi from the A tubulansupporting body a. hose dome sections 2) b are each provided witha shoulder 3, and they may be opened out, as shown in Fig. 3, or closed, as shown in Figs. 1 and 2, and when closed, as shown in Figs. 1 and 2, the central aperture therein is large enough to receive the base of the lamp socket and to fit over the same for support. The

outer member or tubular locking sleeve is 7 provided with aparallel sided part a, .a short threaded part 0 an inturned top flange 9-, preferably with perforations'lO, with a flarlng part 0 0 This outer part or tubular locking ment outside of the inner part and in axial line therewith. A

In the position shown in Fig. 1, the shade d is shown in dotted lines, but Ido not limit my invention to the use of a shade,

because the holder is adapted toreceive a pendant sphere or pendant divided spheres,

as such devices are well known in the art.

In' the position Fig. 1, the inner and outer 1parts are in that relation in which the flange 9 as come into engagementwith the shoulder 3, and. the outer part has been moved over the inner part as far as possible, and the parts a and 0 have come into that relation in which the edge of the. shade or sphere is -engaged, for themain reason that the flange 9 has come down to contact with the shoulder 3' and can move no farther. In connecting thes'epart-s to a socket and lamp already in position, the outer and inner parts are separated and the outer part, including the tions 5 t" are then overturned both into the for a longitudinal move- 80 and with a skirt flange of the rim of the shade, "so the inner and position shownby1the overturned member" in Fig. 3. The lamp and socket are then assed. through the inner part so that theamp comes intofthe shade and also so that the dome sections b" b may be swung over into the. position shown in Figs. 1 and 2,

in which their edges come together and the. open portions .surroundthe base of the socket, as shown in Fig. 1, and the domed inner portion and. the shade are ready to be connected and suspended; The outer portion then is passed down over the inner por- "tion and the screw threaded part 0 brought into engagement with the screw-threaded portion a? and the outer part rotating, not only to connect the parts, but to cause the lower end or skirt flange a of the same to 'pass-downover the rim of'the shade as far as possible. In thus connecting the parts, the inner edge of the inturned flange 9 comes into contact with t-he outer edge of the dome sections b b and atonce holds them together, preventing accidental separation, and thereafter, in connecting the parts together,

and in proportion to the thickness and form outer parts are brought nearer to one an-- other, or farther apart. If they come nearer together, the flange 9 comes down-upon the shoulder .3, as shownin Fig. 1. If they are kep t,fa-rther apart, the flange 9 still bears against and around the dome sections 12 b and keeps the same together.- The recess established at the lower end of these axially.

' neck of the shade or pendant sphere and is.

moving. parts, or in other words, between" thelowerpart of the body a and its flange a. and the flaring partc and skirt flange a" of the outer'part, provides for the rim or ample to receive and accommodate said part,

' substantially regardless of its reasonable configurat on or area.-

The device ofmy invention is generally adapted to receivet-he rim or neck of any shade orsphere made, and to support'the same from the. axially movingparts, and" primarily from the socketand its support.

- These parts are exceedingly simple in con.-

' to a shade or pendant sphere.

struction, are readily connected and disconnected, require noscrews or small parts for their movement or control, or for connection I claim as my invention:

1. A holder for shades, globes, or reflectors for electric fixtures, comprising a tubular supporting body having attached movable dome sections, and a surrounding and' locking sleeve adapted for axial. movement and engagement ivithsaid tubular' body and to be passed over parts of the fixtures without dismantling the same 2. A holder for shades, globes, or reflectors for electric fixtures, comprising a tubular supporting'body, movable dome sections connected theretofne'ar its upper end and adapted. to permit the lamp and socket to be passed through the'tubular body,.said body and dome section s" forming a cov er for the socket, and a surrounding locking sleeve adapted 'for axial movement and engagement with the tubular supporting body.

3-. A holder for shades for electric fixtures, comprising a tubular supporting body having' a v flanged lower edge, and dome sections connected thereto in' a hinged relation, a

:locking sleeve of tubular sheet metal, adapt ed to surround the tubular supporting body same in a hinged relation to the upper end of thejtubular supporting body, an outerlo'cking sleeve part adapted foraxial movemerit in relation to the body, the-same having' a short screw-threaded portion to be engaged with the tubular body as rotated about-the same, and having a flange at the lower end between which and the flange of the supporting-body the shade or sphere is to be en aged 'at'jits rim .or neck.

5. A ho der ,for 'for electric fixtures, comprising a; tubular-supporting body having a flange at thelo wer end and a screwthreaded portion, similar dome sections and ine'ans for connecting thejsame in a hinged- -relation to'the upper end of the tubular supportingbody, an outer locking sleeve. part adapted for axial movement in relation t o'thebody, the'-samehaving a short screw-thread- .ed portion to be engaged with the tubular body as rotated about the same, and having" a flange atthe lower end between which and the. flange of the supporting body the shade or sphere is to'be engaged at its rim or neck, and the outer locking sleeve part having an int-urned flange atits upper end 7 adapted to surround -the dome sections of the inner member-or supporting body and maintain the dome sections together in a fixed relation substantially independent of an appreciable longitudinal movement of the outer part inits relation to the inner part.
