CANDLE-MOLD.

Specification of Letters Patent No. 26,429, dated December 13, 1859.

To all whom it may concern:

Be it known that I, ΙΓλτλόε Halvorson, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented 5 a new and useful Improvement in CandleMolds; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of 10 this specification, in which—

Figure 1, is a central longitudinal section of the whole mold containing a candle. Fig. 2, is an external view of the inner tube of the mold. Fig. 3, is a transverse section of 15 the same. Fig. 4, exhibits the outer tube of the mold in section and the inner one entire. Fig. 5, is a top view of the complete mold.

Similar letters of reference indicate cor20 responding parts in the several figures.

The object of my invention is to facilitate the removal of the candles from the mold and prevent the inconvenience which frequently results from their “ sticking ” in the 25 molds heretofore commonly employed, and to this end the nature of my invention consists in constructing the mold of two tubes one fitted within the other and with a “ tip ” of elastic or yielding material the outer tube 30 being rigid and as much larger than the candle as to adinit within it the inner one, whose interior is of the desired size of the exterior of the candle, and which is made with a longitudinal slit and to possess such 35 elasticity that when not confined within the outer one to such a degree as to keep the edges of its slit close together it will expand and release the candle which has been molded in it, and the tip being fitted into the 40 inner tube.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, is the outer rigid tube made of any 45 suitable metal or material with its interior of the taper that is desirable for the candle and open at both ends. B. is the inner or slit elastic tube of corresponding taper to fit the outer tube A. This inner tube may 50 be made of any sufficiently elastic metal, in any suitable manner so that when the two edges of its slit a, which are parallel w-ith each other, meet, its interior shall be of the required size of the candle, and it is pol55 ished internally. Into the smaller end of this tube is fitted the tip C, which may be of cork or any other slightly elastic or yielding material that will not fail to permit the closing of the slit «·, of the tube B, having a hole through it for the wick D, to pass 60 through and having a cavity in its inner end of the required form for the tip of the candle.

The manufacture of candles in this mold is as follows: The tube A, being placed up- 65 right with its larger end upward, the tube B, is placed in it and pushed in so far as to cause the closing up of its slit. The wick is then passed through the tip C, and knotted at one end to prevent its being 70 drawn through, and it has a pin or piece of wire δ, secured to the other end to lie across the upper end of the mold, or is otherwise provided with means of sustaining it in the center of the mold; and the tip C, is afterward 75 placed in the tube B, and pushed down as far as is necessary leaving the pin δ, resting on the top of the said tube, after which the material is poured into the mold and allowed to remain therein until it has con- ⁸⁰gealed or become hard, when the pin δ, is removed and an upward pressure is applied, by any contrivance that will not touch the candle, to the lower end of the tube B, till the said tube becomes elevated so high in ⁸⁵the outer tube A, as to be permitted by the latter to expand by its own elasticity, to a sufficient degree to leave the candle loose within it. The candle may then be pulled or pushed out of the mold with the tip C, re- ⁹⁰maining attached, without having its exterior marred in the slightest degree, and on the knot in the wick being cut the tip C, may be easily detached from it. A fresh wick is then inserted in the tip and on the ⁹⁵latter being replaced in the tube B, and the said tube being pressed into A, till its slit is closed the mold is ready to receive the material for another candle.

I prefer in the manufacture of candles ¹⁰⁰for the sake of making them very solid to subject them to pressure after the material has become congealed but before it becomes too hard, and this pressure may be effected by the aid of the tube B, by inserting the ¹said tube before the pouring, only so far into the tube A, that the slit will not be quite closed, and then as soon as the material is congealed, applying to the larger end of the tube B, sufficient pressure to force it in

26,429 far enough to close its slit, by which means the material will be pressed from all sides toward the wick.
