Improvements in Candle Moulds
We, WILLIAM HARPER DAY, Candle Machine Manufacturer and Pewterer, and
WILLIAM MURCH, Engineer, both of the Novelty Works, Hounslow, in the
County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in candle moulds employed
in candle making machines with a view to strengthen the same without inter-
fering with their free conductivity of heat.
For this purpose we construct the candle mould of any usual or suitable
material but instead of obtaining strength in such mould by thickness of sub-
stance we make it comparatively thin and strengthen it by means of a thin
tube or sheath of steel or other strong metal closely fitting the exterior of the
mould and which may extend the full length of the latter or only partly along
the length thereof in which latter case the unsheathed part of the mould is
preferably somewhat thicker than the other part.

Improvements in Candle Moulds.
We, WILLIAM HARPER DAY, Candle Machine Manufacturer and Pewterer, and
WILLIAM MURCH, Engineer, both of the Novelty Works, Hounslow, in the
County of 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 following statement:
―
The invention has for its object improvements in candle moulds employed
in candle making machines with a view to strengthen the same without inter-
fering with their free conductivity of heat.
For this purpose we construct the candle mould of any usual or suitable
material but instead of obtaining strength in such mould by thickness of sub-
stance we make it comparatively thin and strengthen it by means of a thin
tube or sheath of steel or other strong metal closely fitting the exterior of the
mould and which may extend the full length of the latter or only partly along
the length thereof in which latter case the unsheathed part of the mould is
preferably somewhat thicker than the other part.
And in order that our invention may be more clearly understood and readily

page_text: carried into effect we will aided by the accompanying drawings more fully
describe the same.
In the accompanying drawings Fig. 1 is a longitudinal section of a candle
mould having a portion of its length strengthened according to our invention
with a tube or sheath flush externally with the other portion or body of the
mould. Fig. 2 is a longitudinal section of a candle mould similarly strengthened
to Fig. 1 but having the tube or sheath projecting beyond the exterior of the
general body of the mould. Fig. 3 is a longitudinal section and Fig. 4 is an
exterior view of a candle mould having a strengthening tube or sheath extending
its entire length.
The body a of the candle mould is constructed of any usual or suitable material
such for instance as pewter or tin-pipe" alloy which is cast in suitable moulds
as is well understood but according to our invention instead of obtaining strength
in such mould by thickness of substance we make it comparatively thin and
strengthen it by means of a thin tube or sheath of steel or other strong metal
closely fitting the exterior of the mould and which may extend the full length
of the latter as shown at Figures 3 and 4 or only partly along the length thereof
as shown at Figures 1 and 2 in which latter case such strengthening tube may
as shown at Fig. 1 be flush with the exterior of the part a which latter is cast
with its unsheathed part somewhat thicker than the part covered by the tube
or sheath b.
In the example shown at Fig. 2 the mould is cast of the same thickness from
end to end and the tube or sheath projects beyond the surface of the general
body of the mould.
In the example shown at Figures 3 and 4 the tube or sheath b extends from
end to end of the mould.
In constructing moulds as above described we first cast the body a of the
mould without the collar a¹, the tube or sheath b is forced on to the cylindrical
part or body a, the collar a¹ is then placed in position and the whole is then
soldered firmly together, the part marked 6 representing a mass. of solder.
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. An improved candle mould constructed as herein set forth.
2. A candle mould strengthened by an external tube or sheath of steel or
other strong metal extending. partly or. entirely. along the same substantially as
herein set forth.
3. A candle mould made of comparatively thin material and strengthened by
an external tube or sheath of steel or other strong metal extending partially or
entirely along the same, substantially as herein set forth.
