Improvements in or relating to Moulds.
We, WILLIAM HARPER DAY, Candle Machine Manufacturer and Pewterer, and
WILLIAM MURCH, Engineer, both of Novelty. Works, Hounslow, Middlesex, do
hereby declare the nature of this invention to be as follows:-
.
This invention consists of improveinents, in or relating to moulds, the object.
being to strengthen moulds so as to prevent their bursting without unduly
increasing their thickness and also to ensure the required amount of con-
ductivity of heat.
For purposes of illustration I will describe a convenient way in which I
carry out my invention as applied to moulds for candles, but it must be under-
stood that I do not confine myself to this particular description of the way in
which I carry out the object of my invention as there are a number of modifica-
tions which may be made without departing from the principle thereof.
With regard to the mould for candles, I find it convenient to employ a
strengthening body such as wire of any suitable material. I find that copper
wire is well applicable for this purpose owing to its good conductivity of heat.
This copper wire may be wound around the body of the mould in the form of
a coil attached or connected thereto in any convenient manner, or it may be
incorporated with the material forming the body of the mould in the process
of manufacture. I describe the employment of wire as a strengthening body
in order to show that the incorporation with, or attachment or connection to the
body of the mould of a strengthening body is, the essential feature of my
invention and I do not confine myself to any particular arrangement or material
or means for carrying out the object of my invention. For instance, it might
be convenient to employ, instead of copper wire, a form of gauze frame or
strengthening ribs or intersecting pieces which might be incorporated with,
attached or connected to the body of the substance forming the mould; as the
essential feature, as has been before pointed out, is the construction of a mould
of sufficient strength combined with the required conductivity without abnormally
increasing the thickness of the mould, and this end is attained by the combination
with the body of the mould of the strengthening adjunct. The mould may be
connected or attached in the required position through the medium of any
suitable form of nozzle or connection and the material of which this nozzle or
connection is composed may be such as to suit the circumstances in which the
mould is employed.

page_text: We, WILLIAM HARPER DAY, Candle Machine Manufacturer and Pewterer, and
WILLIAM MURCH, Engineer, both of Novelty Works, Hounslow, Middlesex, 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 follow-
ing statement:-
This invention consists of improvements in or relating to moulds, the object
being to strengthen moulds so as to prevent their bursting without unduly
increasing their thickness and also to ensure the required amount of conductivity
of heat.
For purposes of illustration we will describe a convenient way in which we
carry out our invention as applied to moulds for candles, but it must be under-
stood that we do not confine ourselves to this particular description of the way
in which we carry out the object of our invention as there are a number of
modifications which may be made without departing from the principle thereof.
With regard to the mould for candles, we find it convenient to employ a
strengthening body such as wire of any suitable material. We find that copper
wire is well applicable for this purpose owing to its good conductivity of
heat. This copper wire may be wound around the body of the mould in the
form of a coil attached or connected thereto in any convenient manner, or it
may be incorporated with the material forming the body of the mould in the
process of manufacture. We describe the employment of wire as a strengthening
body in order to show that the incorporation with or attachment or connection.
to the body of the mould of a strengthening body is the essential feature of
our invention and we do not confine ourselves to any particular arrangement or
material or means for carrying out the object of our invention. For instance,
it might be convenient to employ instead of copper wire, a form of gauze frame
or strengthening ribs or intersecting pieces which might be incorporated with,
attached or connected to the body of the substance forming the mould, as the
essential feature as has been before pointed out is the construction of a mould
of sufficient strength combined with the required conductivity without abnormally
increasing the thickness of the mould, and this end is attained by the com-
bination with the body of the mould of the strengthening adjunct. The mould
may be connected or attached in the required position through the medium of
any suitable form of nozzle or connection and the material of which this nozzle
or connection is composed may be such as to suit the circumstances in which
the mould is employed.
For purposes of illustration, we will now refer to the annexed drawings.
Figure 1 is a section of a mould constructed according to our invention..
is the inner casing or tube which is surrounded by the wire b, and this wire
may be embedded or carried in any suitable material c. The number of layers
of the coil of wire will depend upon the strength required for the purpose of
preventing bursting of the mould.
We find that copper wire is applicable for this purpose owing to its good cou-
ductivity of heat. This copper wire may be wound around the body of the mould
in the form of a coil attached or connected thereto in any convenient manner,
or it may be incorporated with the material forming the body of the mould in
the process of manufacture.
We describe the employment of wire as a strengthening body in order to
show that the incorporation with or attachment or connection of the body of the

page_text: mould of a strengthening body is the essential feature of our invention, and
we do not confine ourselves to any particular engagement of material or means
for carrying out the object of our invention.
It will be readily seen that we might for instance employ instead of copper
wire, a form of wire gauze or strengthening ribs or intersecting pieces which
might be incorporated with attached or connected to the body of the substance
forming the mould, as the essential feature of the invention as has been before
pointed out is the construction of a mould of sufficient strength having the
required heat conductivity without abnormally increasing the thickness of the
mould, and this object is attained by the combination with the body of the mould
of the strengthening adjunct.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. In moulds of the class herein described, the combined construction and
arrangement of the various parts, substantially as described and illustrated herein
and for the purpose set forth.
2. In moulds of the class, herein described strengthening the mould and
increasing its heat conductivity through the employment of a strengthening
adjunct which may be embedded in the substance of the mould or carried,
attached or fixed to the exterior thereof; substantially as described and illustrated.
herein and for. the purpose set forth.
3. In moulds of the class herein described, the employment of a layer or layers
of copper wire or other suitable material wound around the substance forming
the mould or embedded or carried therein substantially as and for the purpose
set forth and described and illustrated herein.
