PROVISIONAL SPECIFICATION left by the said John Nield and Thomas
Arthur Nield at the Office of the Commissioners of Patents, with their
Petition, on the 17th June 1862.
We, JOHN NIELD, Ironfounder, and THOMAS ARTHUR NIELD, Engineer,
both of Dukinfield, in the County of Chester, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN. MOULDING OR MANUFACTURING PIPES,
COLUMNS, OR OTHER SIMILAR ARTICLES OF CAST IRON OR OTHER METALS," to be as
follows:-
In: moulding or casting socket, or faucet, or flange pipes, either with
or without snugs and sockets, either at the top or bottom; we place the pattern
or patterns half way through a frame which. stands in a vertical position and
is fitted with pins: to guide the..moulding box to its proper place against the
frame. The pattern or patterns may. be fixed on. hinges passed into slides or
any other convenient method, so as to allow them to be removed from the sand,
and are held in their places. by pins or other suitable contrivance, whilst the

page_text: moulding boxes are being rammed up, the said boxes being perforated to allow
the escape of gas or steam, and are made cylindrical, but in halves longi-
tudinally, with flanges, both outside, inside, and at the ends. The flanges
outside are for the purpose of fastening the halves together, either by clams,
wedges, pins, cotters, bolts, or other suitable means. The flange on one end
is to fasten the plate or seating and the box together, after the core is intro-
duced; and the flanges inside the box are to prevent the sand falling out.
The mould for the flange pipes has a plate covered with loam or sand to
cover the top flange, the gates being in the said plate; and the gates for casting
socket or faucet pipes are on the top end of the pattern, the bottom flange
being moulded in a recess in the seating plate, which recess is perforated for
the escape of gas or steam.
gas or steam. The moulding frame, boxes, and seating plate
are all faced to fit true to each other, and the seating for socket pipes has a
ledge in the inside; the core barrel is also faced at the end, so as to fit the
ledge in the hole of the seating. This system of moulding is peculiarly
applicable to dry sand, but may be also used for green sand. The said frame
may be constructed in separate parts, to allow pipes of various diameters to be
moulded on the same frame; and the boxes and frames may be made so as to
mould any required number of pipes at the same time. It is evident that this
system of moulding is also applicable to casting shafts, columns, cylinders, and
similar articles, either solid or hollow, and round, square, or other required
form.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Nield and Thomas Arthur Nield in the Great Seal
Patent Office on the 17th December 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
NIELD, Ironfounder, and THOMAS ARTHUR NIELD, Engineer, both of Dukin-
field, in the County of Chester, send greeting.

Patent, bearing date. the Seventeenth day of June, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Nield and Thomas Arthur Nield, Her special licence that we, the
said John Nield and Thomas Arthur Nield, our executors, administrators, and
assigns, or such others as we, the said John Nield and Thomas Arthur. Nield,
our executors, administrators, and assigns, should at any time agree with, and

page_text: 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 OR
MANUFACTURING PIPES, COLUMNS, OR OTHER SIMILAR ARTICLES OF CAST IRON OR
OTHER METALS," upon the condition (amongst others) that we, the said John
Nield and Thomas Arthur Nield, our executors or administrators, by an instru-
ment 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 John Nield and Thomas Arthur Nield,
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 (that is to say):-
This Invention relates to the moulding or manufacturing of faucet pipes
with a faucet either at the top or bottom, with or without snugs, and flange
pipes with or without margins or brackets, and also cylinders, rollers, columns,
or shafts, solid or hollow, either round, square, or of any other form.
The patterns are placed half way through a frame constructed for the purpose,
which frame stands in a vertical position, and is fitted with pins to guide the
moulding box to its place; the pattern or patterns are held by hinges, or
adjusted to their places by pulleys and slides, or other contrivance, so as to
be drawn out by hand or machinery, the said patterns being held in their
places by pins fixed for that purpose during the process of ramming. The
frame may be so constructed as to admit of pipes or articles of different
diameters being moulded, and one or more articles at the same time. The
boxes are made to hold one or more pipes or other articles, and are
cylindrical or of any other required form, but they are made in halves
longitudinally and are perforated to allow the escape, of gases and steam, and
have flanges at the top, bottom, and sides. In the inside of the boxes are
flanges or ledges to keep the sand from falling out. The flanges on the sides.
are to fasten the half boxes together, and the flanges at the bottom are to fit
on the seating plate, which plate, can be made to answer for different sizes,
either of socket or flange; pipes. The bottom flanges are moulded in the
recesses of the plate, which recesses are perforated, hoops being made to fit the
seating for different sizes of pipes. The parts of the frame, boxes, and seating,
which come in contact, are faced to fit true to each other. The
: The core barrel

page_text: has a hoop at each end to enable the cores to be made true, the hoop at the
bottom being tapered to fit the seating. This system may be applied to
either dry sand or green sand moulding.
This Invention will be clearly understood by referring to the figures and letters
on the accompanying Sheet of Drawings, in which Fig. 1 is a back view, Fig. 2
an end view, and Fig. 3 a plan of our improved frame, arranged for holding three
patterns; Fig. 4 a front view, with part in section, of our moulding box and
core barrel; Fig. 5 a transverse section, and Fig. 6 a plan of the same; Fig. 7
a sectional plan of the moulding box shewing the inside flanges, and Fig. 8 a
vertical elevation of our improvements connected with the core barrel; Fig. 9
a detached view of a flange pattern, with core print on; and Fig. 10 is a plan
of a moulding box for small pipes or other articles.
In the aforesaid. Figures, a are the patterns held by bolts or other means to
the cross bars b, c, the top one having pivots at its ends for carrying guide
pulleys d; the bottoms of the patterns have rollers e, to enable them to move
easily. The frame in which the patterns are placed is composed of two end
standards f, bolted at the bottom to the bed plate g, and at the top to the cross
'frame h. Between the two end standards there are a number of other
moveable standards i, held in their required positions according to the diameter
or size of the patterns, by the bolts k,l. The two end standards f are provided
at their backs with two brackets m, on which work the pulleys d, for guiding
the patterns to their places in the frame. The patterns project half way from
the front of the frame, against which is fixed the moulding box n, held at the
bottom by the pins o, and at the flanges by the bolts g, or other suitable
means.
Each compartment of the moulding box has flanges or ledges in the inside,
as at r, to prevent the sand from falling out, and also has perforations s to
allow the escape of gases and steam. There are two moulding boxes, alike
in every particular, and when one half of the mould has been formed the box
is removed, and another box adjusted to the frame, for procuring the other
half of the mould. The flanges p on the sides of the boxes are also for
fastening the halves together either by clams and wedges, pins, cotters, bolts,
or other suitable means, and the flanget at the bottom is to fit on the seating
u, and both flanges are held in their proper places by the pins v. The
seating plate is adjusted to answer for different sizes of socket or flange pipes,
the bottom flanges being moulded in recesses w in the plate, which recesses
are perforated, as at x. The holes y for holding the core barrels are conical,
to insure correctness of fitting, and the end of the core barrel is mounted with
a hoop to fit the hole, but for smaller core barrels an additional hoop is placed

page_text: in the hole y. At the joints of the boxes and flanges there are recesses for
holding sand, and thereby preventing the ends of the pipes from coming in
contact with the metal seating plate.
The standards of the frame, Figs. 1, 2, and 3, may be made of one piece or
casting, when intended for only one sort or diameter of pipes, or other articles.
In Fig. 9, representing the flange, the pattern c¹ is the core print for
moulding the flanges in the recesses of the seating plate u, in Figs. 4 and 7.
In Fig. 10, representing a plan of a moulding box for small pipes or other
articles, the box is shewn at a¹; it is formed in one compartment, but
has at the bottom inside flanges or feet 61, for preventing the sand from
falling out.
Having now described the nature of our said Invention, and the manner in
which the same is to be performed, we desire it to be understood that we
claim, for moulding or manufacturing one or more pipes, columns, or other
similar articles of cast iron or other metals, the employment of the upright
frame, boxes, seating plate, and the hoops on the end of the core barrel, as
herein-before described, and illustrated in the accompanying Sheet of
Drawings.
In witness whereof, we, the said John Nield and Thomas Arthur Nield,
have hereunto set our hands and seals, this Sixteenth day of December,
in the year of our Lord One thousand eight hundred and sixty-two.
Signed, sealed, and delivered by
the within-named John Nield
and Thomas Arthur Nield, in
the presence of
