IMITATIVE CANDLE FITTING.
:lhis invention relates to a decorative form of electric light fitting made to lnntate the appearance of a candle and particularly concerns improvements in the design and mechanical construction of so-called candle fittings when they are of the removable type requiring no wiring to install, such as form the subject of'my two co-pending applications, Serial No. 534-,996, filed February 8, 1922, and Serial No. 543,880,- filed March 15, 1922. 1
Among the objects of the invention are to increase the degree to which such an attachment shall resemble the more expensive and specially designed candle fixtures by concealing more completely the original appearance of the ordinary socket fixture to which my attachment is applied.
The improvements constituting my present invention are also usable to good advantage in the manufacture of 'so-ca-lled socket eXtensions which are commonly provided with a male threaded plug atone end for mounting in anordinaryelectric lamp socket, and with a female threaded receptacle at the other end to receive an ordinary electric lamp bulb, and in any' tubular device employing metallic threaded screw shells or like members atone or both of its ends.
A particular provision of the present improvements is a novel means for mounting an inner body structure inside of a'tube made of paper or correspondingly soft material, in a'secure and simple manner and by a very simple and cheap operation,
whether or not such tube and structure are designed for use as electrical fittings.
The invention is more definitely set forth in the following description, which with the accompanying sheet of drawings, gives specifications of a preferred embodiment which is subject, however, to many departures and modi'fications within the scope of the appended claims.
In the drawings, Fig. 1 is a vertical central section taken lengthwise through the two main parts of my improved candle fitting, the socket to which they are applied and which they largely conceal, when :1 plied, being indicated by dot-dash lines.
Fig. 2 is a perspective view of the body structure that is mounted inside the paper pressed outwardly candle tube, a section'o-f connecting tubular wall being broken away.
Fig. 3 shows an assembling tool as it engages with the structure of Fig. 2 and with the paper tube to fasten the former securely withm the latter. I
Fig.- 1 is. a transverse section'taken 0n. the
plane 55 in Fig. 1 looking down, the
in the position they occupy beforebeing into the paper tube by the tool shown in Fig. 3.
Fig. '5 is a view-similar to Fig. 4 after the prongs are set into-the-wal ls of the paper tube.
Throughout. the different views of the drawings each part is designated by 'a likesymbol.
' The parts of my improved fitting comprisethe outer paper tube 10, the'female screw shell 11,.to which thespider 12 is fastened by eyelets 13,the male screw shell 14 to which is fastened a similar spider 15 by eyelets 16,a metal tube 17 which spaces the spider 12' from the spider 15 against the pull of the long, center screw 18 whose head clampsthe center contact washer 19 and insulating block 20a gainst the male screw shell 14 and whose threaded end by-means of the nut 21 clamps the center contact tongue 22 and insulating washer 23 against the female screw shell 11. r In the original forms of tions 25 are flattened as hereinafter described. It will be seen in- Figs.'2 and '3 that the two spiders are asssembled in ro-' tativel'y staggered prong-ed portion of one falls axially op posite the space between the pron'ged portions on the other. This permits atube-like tool 26 composed of two similar parts havspider, 12 and 15, 'as shown in Figs; 3 and 4, the prongs 2% are radially retracted by 'tran'sradialgrooves The spiders 12and'15 may relation so that the 1 ing inter-engaging castellated ends 27 to encompass the screw shells and fit loosely inside the paper casing and apply longitudinal pressure simultaneously on the chain nelled portions 2570f both spider 12 and spider 15 whereby these channelled portions are flattened and the prongs 24 forced out wardly into, but preferably not through, the Walls of the tube 10. The two parts of the tool 26 then separate and are removable from the assembled structure leaving the spiders securely fastened against rotative or lengthwise -movement within the tube. There is thus provided, by a simple and quick operation, a structure having the necessary annular space. between male screw shell 14 and candle tube 10 to enable the metal husk 30 of proper diameter at its small end to slip easily onto the larger diameter portion of the lamp socket and come to rest onthe edge of the socket cap. This husk has a slot 31 to accommodate the shank of a switch key or the bell mouth guide for a pull chain and also gives a little spring to the husk which enables it to accommodate very slight variations in the diameter of V difierentsockets it may be required to fit.
Y The contour, or decorative design, of husk 30 is obviously amatter of choice, the point with which this invention is concerned being that it, together with the tube 10, covers up a larger part of theold socket than has heretofore been accomplished by removable attachments for a like purpose and thereby more completely disguises the appearance of the ordinary lamp socket and more completely transforms it in appearance to resemble a candle fixture.
The ruggedness and economy of manufacturing resulting from the new features of construction herein described will be apparent and the following claims will be taken to include all equivalent constructions which come within the spirit of the invention.
1. A device for securing an electriclamp receptacle shell to the wall of a surrounding tubularsupport, embodying in combination, a mounting plate fixedly secured in transaxial relation to one end of said shell and extending outside the circumference of said shell to provide a mounting flange, the said mounting flange being channeled to provide for radial extension when flattened, thereby to effect mounting engagement of said plate with the wall of saidtubular support and without changing the shape of said plate in portions other than said flange.
2.
