Year: 1866

page_text: LETTERS PATENT to James Foster, of Bury, in the County of Lancaster,
Ironfounder, and John Hollinrake, of the same Place, for the Invention
of "IMPROVEMENTS IN MOULDING PIPES, PILLARS, ROLLERS, OR OTHER ARTICLES
OF A SIMILAR CHARACTER."
Sealed the 11th September 1866, and dated the 9th April 1866
PROVISIONAL SPECIFICATION left by the said James Foster and John
Hollinrake at the Office of the Commissioners of Patents, with their
Petition, on the 9th April 1866.
We, JAMES FOSTER, of Bury, in the County of Lancaster, Ironfounder,
and JOHN HOLLINRAKE, of the same Place, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MOULDING PIPES, PILLARS, ROLLERS, OR
OTHER ARTICLES OF A SIMILAR CHARACTER," to be as follows:-
Our Invention has for its object the moulding of pipes, pillars, rollers, or
other articles of a similar character, with greater rapidity and with less skilled
labour than in common use.
The
To accomplish this we place the pattern of the article to be moulded
between two plates, or in an aperture made in a plate to receive the same in
such a way that the centre or part where the joint of the mould is to be made
shall be in the same plane as the upper surface of the plate or nearly so.
moulding box is now placed over the pattern and on the plate, the said box
having pins fixed on or near two of its opposite corners and holes for receiving
similar pins in the other two opposite corners. The said plate has holes in

page_text: it to receive the pins on the box. The box is now filled with sand which is
punned well round the pattern, which "pattern is supported on a bearer or
bearers, and has two or more indentations or projections so situate that when
the said pattern is turned partially round it smooths the mould and at the
same time is withdrawn therefrom and one-half of the mould is complete, the
box being removed and placed in a position to receive the other half. The
pattern is now brought to its original position and another moulding box placed
over it similar to the last named and the said operation repeated, and the other
half of the mould is now placed on the first half and the mould is complete.
Where cores are required they are placed in the mould before the second half
is placed on the first. One or more patterus may be used in one box when
required. The motion of the pattern when being turned partially round in
the mould is either eccentric or cam like, owing to the shape of that part
which lies on the bearings. We also use a bearing or bearings containing a
pulley or pulleys with flat or curved sides not concentric with the pivot on
which they move, which will, when the pattern is turned partially round,
cause it to smooth and leave the mould.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Foster and John Hollinrake in the Great Seal Patent
Office on the 8th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
FOSTER, of Bury, in the County of Lancaster, Ironfounder, and JOHN HOLLIN-
RAKE, of the same Place, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said James Foster and John Hollinrake, Her special licence that we, the
said James Foster and John Flolliurake, our executors, administrators, and
assigns, or such others as we, the said James Foster and John Hollinrake,
our executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MOULDING
PIPES, PILLARS, ROLLERS, OR OTHER ARTICLES OF A SIMILAR CHARACTER," upon the

page_text: condition (amongst others) that we, the said James Foster and John Hollinrake,
our executors or administrators, by an instrument in writing under our, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said James Foster and John Hollinrake,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Drawings (that is
to say):-
Our Invention has for its object the moulding of pipes, pillars, rollers, or
other articles of a similar character with greater rapidity and with less skilled
labour than in common use.
To accomplish this we place the pattern a of the article to be moulded
between two plates or in an aperture made in a plate b to receive the same,
as shown in the Drawing, Fig. 1 and 2, which represents a plate with four
pipe patterns fitted into the apertures of the said plate 6 in such a way that
the centres or part where the joint of the mould is to be made shall be in the
same plane as the upper surface of the plate b, or nearly so, as shown in the
Figs., Fig. 2 being a cross section of the middle of Fig. 1. The moulding
box is now placed over the patterns and on the plate b, the said box having
pins fixed on or near two of its opposite corners and holes for receiving
similar pins in the other two opposite corners. The said plate 6 has holes
c, d, e, f, in it to receive the pins on the moulding box. The box is now
filled with sand which is punned well round the patterns, which patterns are
supported on a bearer or bearers which are of various kinds. In Fig. 8 the
pattern a is shown in section, also a portion of the plate b. In this arrange-
ment the two rollers 9, 9₁, support the pattern, and are shown in position for
moulding, and have two or more indentations h, h,, or projections so situate
that when the said pattern a is turned partially round, say, through the angle
A, B, C, it smooths the mould, because the surfaces acting on the rollers 9,9₁,
are concentric with the surface of the pattern, but when the pattern is turned
through a greater angle A, B, D, the pattern is withdrawn from the mould
because the indentations h, h₁, are now on the rollers 9, 91, and the centre of
the pattern a is below the face of the plate b. One half of the mould is now
complete, the box being removed and placed in a position to receive the other
half. The patterus a are now brought to their original position and another

page_text: moulding box placed over them similar to the last named, and the said
operation repeated, and the other half of the mould is now placed on the first
half and the mould is complete. Where cores are required they are placed
in the mould before the second half is placed on the first. One or more
patterns may be used in one box when required. The motion of the pattern
when being turned partially round in the mould is either eccentric or cam
like, owing to the shape of that part which lies on the bearings. Fig. 4 shows
a fixed bearing i, the pattern having only one indentation to allow it to fall
and leave the mould; Fig. 5 shows the pattern a lying on an eccentric k,
which, after the pattern has been turned partially round is moved so as to
allow it to leave the mould. We also use a bearing or bearings containing
a pulley or pulleyes with flat or curved sides not concentric with the pivot on
which they move, as shown in Fig. 6, which will, when the pattern is turned
partially round, cause it to smooth and leave the mould. It is found pre-
ferable to support each pattern in two places near the ends, so that a steady
motion both in smoothing the mould and in leaving it may be obtained.
When the pipes have flanges on the ends the pattern is made with a flange at
each end, a little above half a circle, and the pattern is turned half round, the
flange will then have left the mould, or nearly so, and will easily drop clear of
the mould as before stated.
Having described the nature of our Invention, and the manner in which
the same is to be performed, we wish it to be understood that what we claim
is the apparatus herein described, and the combination of parts for the
purposes herein set forth.
In witness whereof, we, the said James Foster and John Hollinrake,
have hereunto set our hands and seals, this Sixth day of October, in
of our Lord One thousand eight hundred and sixty-six.
