This invention'relates to electric lighting devices and portable decorativelighting sets such as Christmas tree lighting outfits.
Among the objects of the "invention is its provision of a device of the character described which shall comprise few and simple parts, form a highly artistic lighting unit, comparatively cheap to manufacture and withal ruggedin construction and practical and efficient'to a high degree. Other objects of this invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists in the, features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction herein after described, and of which the scope of application will be indicated in the following claims.
In the accompanying drawing, in which is shown one of the various possibleillustrative embodiments of this invention. Fig. 1 is a perspective view of at Christmas tree trimmed with an electric lighting outfit and a decorative unit embodying the invention. Fig. 2 is a front elevational view of th improved Christmas tree lighting unit, partly in section to expose the interior construction. I
Fig. 8 is a frontelevational view of the improved Christmas tree lighting unitshown in mounted position, and Fig. 4 is afragmental view inside elevationof the mounting means portion of the device shown in Fig. 2.
Referring in detail tothe drawing 10 denotes an electric lighting device embodying the invention, in the form of a lamp socket unit adapted to be attached to aportable decorative lighting set such as Christmas tree lighting outfits.
Although, as hereshown, the invention may be incorporated in Christmas tree lighting sets or the like portable circuits, the -device 10 forms a unit which may be detachably connected with such sets or circuits.
In Fig. 1, the Christmas tree 11 is shown trimmed with a portable lighting outfit 12,
which extends through the 7 one or more of the screw receptacle outlets,
12 of said outfit beingfconnected with one or. more units 10,by means of adetachable plugf1-3 extending from' the latter; Said plugmaybe of any wellu nderstood con branches thereon" structionand hasconnectedthereto the usual flexible conductor wire's 14; The latter serve as a circuit *extension'between, said plug 13 andf'a decorative fixture member 15 here shown of-"suclr'structure asto simulate a candlewhen fitted with an electric bulb '16, as shown in Figs.- 1 and 3.
The member-15 may comprise an elongated cylindrical shell' or other form ofItubing shell has an integral' conic al closure 15 at the other'end formed with a-nipple 15" j alignedwith' the axis of the cylindrical shell member 15,- saidnipple-extending outwardly e5. 'havingan openencl 15 andiisipreferablyj made, of relatively thin sheetmet'al Said from said closure and f-forming' a passage wherethrough the conductor wires '14 pass from the plug 13 into'said member; The
ends of said conductor wires 14 opposite-said;
. plug, withi'n saidmember 15'connect thecentreand shell terminal contacts 17 andl'? respectively, of'ia screw receptacle outlet 17. 1 Said outlet 17" is mounted concentrically withinithermember"15at the said open end 15 and is-adaptedto receive the bulb 16 j aseis shown in:Fig.-2.
The receptacle outlet 1 7extends within bushing 18madeof any incombustible or firerresistance electrical insulating material such l as a pheno-condensate product, fibre,
orthe like'materials. A fillertubing 19 made of; paper, card-board orylother cheap matefrom-the :walls of the memberlfi. V
collapsing. apartupon rough handling of the frialkeepsthe bushing 18 and outlet17spaced i l WYhen-the member 15. is madeof very thin 7 i sheet naterial, the tubing 19 preferably only partially-fillsthe interior thereof toserve as a lGlIlfOICGIDQHt to preventsaid member from. e
unit .10... The bushing 18need be madeonly f suflicient-ly longtoshieldthetubing 19 from. possible exposure to arcing, if the wiring ex.-
tending through saidtubing becomes defectiVe..
A bead 20 is mounted for sliding movement on the conductor wires 14 between the member and the plug 13.
The practical use of the invention will now be clear.
After the partsare assembled as shown in Fig. 2, the plug 13 may be attached to any suit able outlet receptacle such as socket 12 of a Christmas tree lighting outfit 12. A branch of the tree or other support 21 is inserted between the conductor wires 14: adjacent the closure 15 and the bead is then slid up to clamp the support 21, as is clearly shown in Fig. 4. The unit 10. provided with a bulb 16' may thus bemounted with the member 15 in an upright position to simulate a candle while the flexible conductor Wires 14: permit vconnecting the plug 13 to an outlet receptacle positioned in any angular relation with respect to fitted intovthe open end of said member tosaid member 15. Thus as shown in Fig. 1, for example, while the plug 13 extends horizontally the candle simulating unit 10 may by reason of the flexible connections intermediate the member15 on the plug be adjusted in ordi nary vertical position and maintained in such position by the clamping action of the bead 20, thus giving the desired realistic effect.- The outer surface of the member 15 is preferably finished with a pleasing ornamental decoration which greatly adds to the artistic ap pearance of the unit 10.
It will thus be seen that there is provided a device in which the several objects of this in-' vention are achieved, and which is well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matterherein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
1. A decorative lighting device of the character described simulating a candle comprising a tubular member having an open end, an"
integral closure for the other end of said memher having a central opening therein, an insulating bushing, a filler piece surrounding said hvsnset bushing, said bushing and piece being snugly form a reinforcement for the latter, a recept-acle outlet adapted to receive an'electric bulb carried by said bushing, and flexible conductor wires connected to said outlet, said wires extending through said bushing member and the closure opening as and for the purpose described and specified. v
2. A lighting device of, the character described simulating a candle comprising a .tubular shell member having an open end, a conical' closure for the otherend of said member having an opening extending axially with re.-
spect to the latter, an electrically insulating
