PROVISIONAL SPECIFICATION.
Manufacture of Variegated Candles, and Apparatus therefor.
I, JULES DAVID, of 1 ts Rue des Bourbonnais, Lyon-Vaise (Rhône) France,
Chemical Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the manufacture of candles presenting fluted ribs of
various colours. For this purpose I provide moulds, star shaped in section. In
the first mould, which has its rays truncated and terminating in flat faces, I cast a
candle of any desired colour. I transfer this candle to another mould the rays of
which extend farther from the centre terminating in angles slightly rounded, and,
having warmed this mould, I pour into it molten stearine of some different colour
so as to fill the triangular spaces of the rays. On rapidly cooling the mould, the
candle is removed presenting ribs of colour different from the body of the candle.
Obviously there may be a greater number of moulds to produce fluted ribs
presenting a greater number of colours.
The fluted ribs may be helical, the moulds being suitably formed to produce these.
I group several moulds of each form in casings which can be rapidly supplied
with hot or cold water.

Manufacture-of Variegated Candles, and Apparatus, therefor.
I, JULES. DAVID, of .1 Rue des Bourbonnais Lyon-Vaise (Rhône) France,
Chemical Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
My invention relates to the manufacture of candles in two or more parts having
different colours, that, are united together by the casting.
For obtaining this result I employ two moulds if two colours are to be obtained,
three moulds for three colours, and so on.
By way of example I will describe the manufacture of candles in two colours.
I will assume the case of a mould for candles with seven ribs. or flutings such as
shewn at Fig. 1 of the accompanying drawing.
It will be seen that if the extreme points A. BCDEFG be cut off at the
circle indicated by a dotted line, a new form of mould will be obtained as at
Fig. 2. By means of steel mandrils I construct candle moulds having the section
at Fig. 2, whereby I can cast ribbed candles having the same section. On then
introducing such candles into moulds having the configuration at Fig. 1 it will be
P

page_text: seen that spaces will be left in the mould corresponding to the points A B C
DEF G.
The moulds Fig. 1 with the said candles made from the mould Fig. 2 placed in
them, are then heated to 50° C. in copper casings containing water at that
temperature; I then fill in the spaces A B C &c. with coloured stearine heated to
80° C., and, immediately afterwards I cool the moulds by rapidly introducing
cold water in the cases surrounding the moulds. The material in the said
parts A B C &c. will at once solidify and will form one piece with the candle of
the mould Fig. 2.
Thus the points A B C &c. being of a candle material of a different colour from
the body of the candle, a candle with multicoloured ribs or flutings is obtained,
having a very handsome appearance.
If, in place of two moulds employ three moulds constructed and operating in
a similar manner, candles will be obtained having three different colours, as at
Fig. 3, and in like manner candles with four or more different colours can be
obtained.
It will be obvious that the two moulds Figs. 1 and 2 may be constituted by
having only a single mould as Fig. 1 and filling the points A B C &c. with
removeable rods for producing the candle of the form Fig. 2, and then removing
the rods so as to leave the spaces A B C &c. to be filled in.
The ribs or flutings may either be straight or they may be helical or otherwise
formed.
Fig. 4 shews a candle of circular section with stripes of a different colour from
the body, produced by first casting a ribbed candle in a corresponding mould, and
then, after placing the candle in a circular mould, running into the spaces between
the ribs material of a different colour.
:
Fig. 5 shews a form of ribbed candle in two colours, similar to Fig. 1, but in
which the ends of the ribs are grooved for receiving the material of different
colour.
Fig. 6 shews a candle of the same nature as at Fig. 1, but in which the ribs or
flutings are supposed to run helically round the candle, instead of being straight.
The apparatus which I employ by preference for manufacturing the above
described multicoloured candles consists of 10 cases containing each 20 candle
moulds; 5 cases have moulds of the configuration shewn at Fig. 2, and 5 cases have
moulds like that at Fig. 1. The cases are arranged to receive hot water or cold
water at will by means of cocks on the hot and cold water supply.
The candles having been cast and cooled in the moulds Fig. 2, they are removed
from the moulds by any suitable means, and are conveyed to the moulds Fig. 1.
The casings of these moulds are then heated and differently coloured stearine
at 80° C. is run into the spaces A B C &c. after which the moulds are rapidly
cooled. After about 15 minutes the candles can be removed from the moulds, the
different coloured points of the ribs having become united into one with the body
of the candle.

"
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1
1. The manufacture of multi-coloured candles by first casting the body of the
candle in a mould and then introducing such candle into one or more other moulds
so formed as to leave spaces between such mould and the body of the candle, which
spaces are then filled in with material of a different colour, substantially as
described.
2. As new manufactures, multi-coloured candles produced by the process referred
to in the first claim.
3. For the production of candles according to the process referred to in the first
claim, the arrangement of moulds in such manner as first to enable a candle body

page_text: to be produced in which portions of the complete candle are wanting and secondly
to enable such missing portions to be supplied to the candle in material of one or
more different colours, substantially as described.
