2 Claims. (Cl. 1S--58) The invention relates to wax candles and their manufacture.

An object of the present invention is to provide a method of manufacturing long, stately tapers having the desirable appearances of long hand-dipped tapers but at much lower labor and material costs.

Another object of the present invention is to provide a candle which will better hold and maintain its stately, erect shape during burning and will have less tendency to slump, bend or droop than the hand-dipped tapers presently available.

A further object of the present invention is the provision of a device that will aid in the herein described process of producing, relatively, low-cost candles having a variety of shapes including relatively complex spirally fluted forms.

Still another object of the present invention is to provide a candle construction of the character hereafter described which makes optimum use of waxes having different qualities and characteristics, particularly in the core and shell portion of the candle.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is understood, however, that variations in the showing made by said drawing and description may be adopted within the scope of the invention as set forth in'the claims.

Referring to said drawings:

Figure 15 is a cross-sectional view of the candle taken substantially on the plane of line =15--15 of Figure 14.

The candle of the present invention and as illustrated in the accompanying drawing, see Figures 7 and 8, consists, briefly, of an elongated tubular wax shell member 21, an elongated wax core member 22 mounted within the shell member 21, a Wick 23 carried by and extend: ing longitudinally through the core member 22, and from one end 24 of the shell member for lighting of one end 26 of the wick, and circumferentially spaced radially extending portions 27 on one of the members 2122 engaging and rigidly supporting the other member in spaced relation. Preferably the shell member 21 is formed with longitudinal taper toward its normally upper end 24, and the radially extending portions 27 are formed with a similar taper so as to provide a snug fit at at least spaced points over the length of the two telescopically arranged sections.

In the preferred form of the invention as illustrated in Figures 6 and 8, the Wax core member 22 is formed with a plurality of circumferentially spaced longitudinally extending ribs which provide the radially extending portions 27 aforementioned, and these are tapered toward the normally upper end 28 of the core member to conform to the taper of and to engage and support the internal wall 29 of the shell member 21. As will be observed from Figures 5 and 6, the wick 23 is carried generally axially through the core member and from the upper end 28 for extension of the wick end 26 through an opening 31 provided in the upper end 24 of the shell member.

In the modified form of the invention as illustrated in Figures 9-15, the tubular shell member 21a is formed with an undulating wall which provides the internal radially extending portions 27a for engagement and supporting of the internally contained core member 22a in generally spaced and concentric relation. If desired and as here shown, the aforementioned undulation of the shell may be in the form of a spirally fluted shell wall in which the valleys of the flutes extend inwardly to en gage the core member 22a. By using a plurality of flutes the valley of one flute may be positioned in transversely opposed relation to the valley of a diametrically opposed flute, as best seen in Figures 11, 14 and 15. In the form illustrated, four such spiralflutes are set in parallel relation and at ninety degree intervals around the periphery of the shell member.

In the form of the invention as illustrated in'Figures 9-15, the core member 22a may be of plain, generally cylindrical form, preferably tapered slightly towards its normally outer end 28a in conformity with a small taper provided over the length of the shell member towards its normally outer end 24a. As in the first described embodiment, the wick 23a is carried axially through the core member 22a and has an end 26a extending from the core end 28a for extension through an opening 31a provided in the normally upper end 24a of the shell.

As a further feature of the present invention, the shell member 21 may be conveniently and rapidly formed on an elongated core or form member 32 adapted for dipping into wax 33 as depicted in Figure l of the drawing, for forming of the wax shell 21 on the periphery of form member 32, the particular feature of thepresent invention being characterized in the forming of member 32 of distendable elastic material such as rubber, either natural or synthetic or some suitable composition ,of .the ,two, functioning automatically to reduce in'thickness and ,to shrink away from ,the .shell when pulled .at Lone vend .34 from the normally lower end 36 of the shell so as to place therformlmember .in tension.

'Pre'ferahly,.the;pin,37 'is formedof metal and maybe molded as,aniintegral partroflthelformlmember32.
