It will be understood, therefore, and that in actual practice such a device will that the word cylindrical, as used herein, does not accommodate many times this number for econnecessarily mean a true cylinder but refers to a omy in manufacture. After the containers with 50 construction having functions and structure like the core rods I4 are in place, as shown in Fig. 3,

a cylinder. molten candle wax is poured into the container The casing is preferably of clear glass although to a. point approximately as indicated by the obviously a synthetic organic plastic could be numeral I1 on Fig. 5. 'Ihe wax is then allowed used successfully. The fuel body maybeordinary to cool and in cooling will shrink forming a 55 cavity as shown by the line I8 in Fig. 5. A moldV member I 9 is then inserted in the top of the casing 2, as shown in Fig. 6. This mold member comprises a circular body 20 having a central orifice 2| through which the second pouring of Wax may be made. The inner surface of the body 20 has a conical cavity 22 which, as specically shown, comprises a series of cylindrical or conical sections decreasing in diameter. The upper surface of the mold member has a cavity 23 providing a sprue about the orifice 2|. A circumferential flange 24 abo-ut the body 20 is such that when the body portion sits inside the top of the casing 2 the circumferential flange 24 extends outwardly beyond the edge of the casing and provides means for handling-the mold member. V

'I'he line I1 is so fixed that the bottom edge of the body 20 will contact the surface of the wax when the mold member is inserted. 'Ihe cavity to'be filled is bounded on its upper side by the wall of the conical cavity 22.

A `secon-d pouring of molten wax is made through the orice 2| so that the wax projects upwardly and fills the inner cavity 22 of the mold member as well as the orifice 2| and preferably, to allow for the shrinkage, the top cavity or sprue 23 in the mold member. After the second pouring has been allowed to harden the wax is scraped out of the cavity 23 by an instrument such as a putty knife, and the mold member I9 is lifted from the casing. Because of the uncertainties in the manufacture of glass containers the diameter of the body portion 20 must be made slightly smaller than the usual inner diameter of the castings, to provide for ready insertion and removal, and to provide for tolerances in glass manufacture.

While but two pourings have been illustrated and described, ordinarily depending upon the size and proportions of the casing, an intermediate pouring is required or is desirable before the mold member is inserted. This is illustrated and described specifically in connection with Figs. 7, 8 and 9.

It will be understood that during the first and second pouring of wax the core rod |4 will be in place, as shown in Fig. 3. The clips I3 are so arranged that after the wax has been hardened subsequent to the first pouring the core rod may be removed from the clip I3 and the core member I9 will be placed in position by passing the rod through the orifice 2|.

After the wax has hardened subsequent to the second pouring the core rod I4 is withdrawn. A hook 25 is formed in the upper end of the rod I4 to facilitate its manipulation. The wick 3, which is of stiff material, is inserted into the candle through the hole made by the removal of the core rod I4 and the candle thus is completed.

It has been pointed out that the wax is not lled to the very top of the casing, but to a line I1, as heretofore mentioned and as shown in Fig. 5. It is recommended that this be be tween three-fourths to one inch from the top. In extreme hot weather the wax body will expand and unless this space is left the wax will expand over the top of the casing wall.

The cone or mound Ill at the top of the wax body has been described in detail. The purpose of this cone is to prevent a Well forming in the fuel body, leaving above the wick upwardly extending walls, which by suddenly melting or caving may extinguish the flame. With the mound or cone Ill a reduced fuel body is provided when the candle is lighted and until it is uniformly heated. After the burning has progressed to a considerable extent the entire top of the fuel body will become liquid so that the formation of a well and the accidental extinguishing of the ame is prevented.

The arrangement of the cap 4 with a central flue and a substantially uniform opening about the top of the casing is such as to provide a ickerless and sootless flame and one which is uniform throughout the burning. The outside air to support combustion will enter through the space 9 between the annulus 5 and the top of the casing and flow downwardly in the form of a cylinder toward the flame, while the gases of combustion and the heated air will flow upwardly at the center and outwardly through the ue or central orifice 6 in the cap.

Figs. 7, 8 and 9 illustrate an embodiment of the invention in a container having a restricted mouth. These gures also illustrate an intermediate pouring between the initial pouring and the final one. In this case the container 2 has a restricted mouth 30. Molten wax is poured into the container to a line I1 and upon cooling a cavity I8 will be left. 'I'he line must be substantially below the mouth of the container in order to allow expansion of the fuel body in hot weather. After the initial mass of wax has been cooled, wax is again poured into the container to the line I1 and shrinkage will leave a cavity indicated by the numeral 3|, Fig. 8. A mold piece 32 is then inserted in the neck of the container until the bottom contacts the top of the body of wax.

The mold piece 32 is similar to the mold piece I9 except that it is more elongated in form. It has a central orifice 2|, a bottom cavity 22 and a top cavity or sprue 23.

It has been found that a candle in combination with the cap, as herein described, provides a long burning device with a flame of constant luminosity which will not be accidentally extinguished under any ordinary conditions. A ickerless and sootless flame is produced with a minimum or practically no re hazard. 'I'he method and mold piece provide efficiently for the manufacture of the device.

Various changes may be made in the details of construction, Within the scope of the appended claims, without departing from the scope of this invention, while parts of the invention may be used to advantage without the whole.

I claim:

1. The method of making a candle having a permanent casing comprising, owing molten material into the casing about a central core, allowing said material to harden against the walls of the casing, placing a mold piece within the top of the casing and around the core, and flowing molten material against the top of the hardened material through a central cavity in the mold piece and about the central core to illl such cavity and form a mound on the mate- `mi body.

2. The method of making a candle having a permanent casing comprising, flowing molten material into the casing, allowing said material to harden against the Walls of the casing, placing a mold piece within the top of the casing, and flowing molten material through a central cavity in the mold piecev into a space between the top of the hardened material and the underside of v the mold piece and lling said cavity to mound.

form a 3. The method of making a candle having a permanent casing comprising, owing molten material into the' casing, allowing said material to harden against the walls of the casing, leaving through shrinkage a central cavity, iiowing additional molten material into said cavity, allowing said second owing to harden, placing a mold piece within the top of the casing, and flowing molten material against the top of the hardened material through a central cavity in the mold piece to fill said cavity and form a mound on the material body.
